Water Blocks / Liquid Cold Plates | Thermoelectric Cooling | Peltier Coolers

You must have JavaScript enabled in your browser to utilize the functionality of this website.
Water blocks, also known as Liquid Cold Plates, are the most efficient method of heat removal. They are often 4-5 times more efficient compared to a standard air cooled heat sink and fan. The principle is simple: you provide a source of cool liquid (typically water, or ethylene glycol/water, or Fluorinert) to the inlet of the water block. The liquid travels back and forth through the various chambers of the water block thereby absorbing the heat from the TECs or power electronics. The warmer liquid then exits the water block. The source of the liquid can be;
- Chiller Liquid — A pre-chilled Liquid (typically alcohol, water/glycol, oil, or a dielectric fluid such as Fluorinert) from a recirculating chiller passes through the water block and then is returned to the chiller for re-cooling. This is a closed loop system.
- Radiator closed loop — a liquid enters the water block at close to ambient air temperatures. The exiting warm liquid then goes to a fan cooled radiator of sufficient size to cool the liquid back down to ambient air temperature.
The liquid is then sent back through the water block, This is a closed loop system. - Building (tap) water — This water is usually cooler than the ambient air temperature. The warmer exiting water can be sent to a drain or re-used in a number of ways.
- Well water, lake, or stream water — This water usually requires pre-filtering but can be substantially colder than ambient air temperature, especially during winter months. Exiting water can either be returned to the source or re-used. This is an especially useful method for Off Grid locations.
Liquid cold plates are usually made from either Aluminum or Copper due to their high thermal conductivity. Aluminum liquid blocks are a good all purpose material choice and will suit most needs. Copper liquid cold plates have a thermal advantage in a greater ability to move heat. In addition, it is best to NOT mix metals in a liquid cooling loop as this may cause galvanic corrosion. If you already have brass and/or copper fittings then use a copper cold plate.
If you have aluminum, stainless steel, and nickel fittings, then use an aluminum liquid cold block. All of our aluminum liquid cold plates are anodized for corrosion protection. Our copper cold blocks are supplied uncoated (raw) but can be plated if needed. Please call or email for further information. FAQ on Water Blocks / Liquid Cooling Blocks.
Liquid cooling plates ( Water Blocks ) are used as a cooling solution for TECs, TEGs, IGBTs, MOSFETS, thyristors, SiC, data centers, EV/HEV, alternate energy, battery systems, power electronics and anything that needs a compact highly efficient means of heat removal.
Liquid cold plates can also be used in a reverse purpose. By cooling the block or plate with Peltier devices (or a compressor based refrigeration system), any liquid that is passed through the plate becomes chilled. This is the basis behind making a chiller system. Many customers have used this method of regulating the temperature of a desired liquid or gas before it is subjected to analysis.
By using thermoelectric devices, the temperature of the fluid can be either heated or cooled to a specific temperature.
Water Blocks are also called; Liquid Cold Plate, Water Cooled Plate, Liquid Chassis, Liquid Cooling Plate, Water Cooling Block, Cold Plates, Liquid Cooled Baseplate, and many others and are all the same basic device that uses a liquid to keep it cool.

Chillers, water coolers
For the normal operation of an induction HDTV heater, it is necessary to effectively cool its power elements with distilled or softened and filtered water. Cooling can be organized in various ways.
The simplest cooling device consists of a circulation pump pumping distilled water from a plastic or stainless steel tank. This method is applicable only in the case of occasional use of an induction heater. If you add a copper heatsink with a fan to this device, it will work much more efficiently.
However, most induction heaters start to overheat when the coolant temperature is above 30ºC. And the air-cooled radiator system does not allow to reduce the temperature of the cooling water below the air temperature in the room plus 15º C. This means that during intensive work it will be very difficult to use such a cooling system in the summer. Please note that one of the main reasons for the failure of induction heaters is desoldering due to overheating of the water-cooled high-frequency transformer.
And overheating of modern units of power electronics MOSFET transistors and transistor IGBT modules greatly reduces their service life.
An alternative way to cool distilled water is to use process water with plate heat exchangers. This method allows you to achieve better cooling in the summer. However, it is extremely wasteful in terms of industrial water consumption, due to the small temperature difference and, as a result, weak heat transfer between distilled and industrial water.
We suggest you use industrial chillers (water coolers) as the most economical and automated devices for maintaining the set temperature of distilled water in the cooling system of the induction heater.
In principle, industrial chillers work according to the following principle: the compressor sucks refrigerant vapor from the evaporator and compresses them. The compressed vapors enter the chiller condenser, where they are cooled and condensed. From the condenser, the refrigerant in the liquid state enters the receiver, and from it through the liquid line to the thermostatic expansion valve (TRV).
Passing through the expansion valve, the liquid refrigerant is throttled, turning into a vapor-liquid mixture with a low temperature, and enters the evaporator, where it boils due to the heat supplied to it from the cooled liquid. The regulation of the refrigerant supply to the evaporator is carried out using an expansion valve. The refrigerant vapor generated during the boiling process in the evaporator is returned to the compressor. The chiller is usually equipped with a chilled water pump. The figure does not show the pump.
Due to the fact that heat transfer occurs at a significantly greater temperature difference than in previous devices, heat transfer occurs much more efficiently. This statement applies to both air-cooled and water-cooled chillers. For the latter, a significantly lower consumption of technical water is required.
Of course, air-cooled chillers are more versatile, require no process water, are more economical and are always ready to go. However, they heat the air in the room and for this reason they are located at some distance from the equipment.
Powerful air-cooled chillers have remote outdoor condensers. Water-cooled chillers do not heat the air in the room, but they are less economical due to the consumption of process water.
Of great importance is the selection of the optimal power of the chiller. The chiller does not continuously cool the distilled water. It turns on only when the temperature of the water in the tank rises above the set threshold. If the chiller capacity is low, it will cool constantly and will quickly run out of its resource. If it is large, the chiller will turn on less than normal, however, it will also cost much more.
The use of chillers for cooling induction forging heaters or induction melting furnaces, as well as other heaters built into in-line production lines, can significantly increase the productivity of the line as a whole by eliminating downtime due to overheating of induction heaters.

- How to tell a process water chiller from a chiller?
There are many manufacturers in the chiller market. Water coolers are also called chillers, but it is important to make a clear distinction between a process water chiller and chillers for industrial or non-industrial refrigeration.
Many people think that all chillers for the industrial manufacturing sector are the same, but there is a risk of making a huge mistake that could affect the final choice for manufacturing.
Chiller market
When we talk about refrigeration and climate control systems, we mean systems that can control both temperature and humidity levels in a space. They are commonly used in cold rooms, electrical cabinets or other places where the temperature of the cooling water does not need to be precise and constant.
On the other hand, process water chillers are water-cooled systems, which can be divided into air-cooled and water-cooled, according to the liquid used to cool the condenser. The most common cooling power range for installed systems is from 2 to 750 kW.
Process water chillers for industry provide a high and constant degree of accuracy in outlet water temperature (in all atmospheric conditions) and ensure fluid purity that prevents downstream equipment damage. In fact, process chillers are used to cool industrial equipment that requires the coolant to be free of dirt at an accurate and constant temperature. For example, in all hydraulic circuits of machines, if the oil temperature exceeds a certain limit, the machine shuts down with subsequent loss of performance.
Therefore, accurate and constant cooling is a necessary and important condition for speeding up and improving production processes. When there is a need for accuracy and water temperatures below ambient temperature, precision process coolers offer the only solution. A precision refrigeration chiller is a machine designed to cool water using a refrigeration circuit.
This is a closed circuit which must ensure:
- No waste coolant.
- No control over outputs.
- Water quality control.
- Modularity: expandable.
- Total flexibility.
- You can set the water temperature.
- Independence from environmental conditions.

home and industrial, types, specifications and reviews
The water cooler is also called a chiller and is a refrigerating machine for lowering the temperature of the heat transfer fluid.
Chillers can be divided according to the type of refrigeration cycle into two classes: vapor compression and absorption. Each of them will be described in more detail later in the article.
In order to make the right choice, you must determine the parameters of the system and the features of the external and internal operating conditions. Only then will the chiller work correctly and perform its functions properly.
Overview of absorption chillers
Hot water is used as the main source of energy for cooling in these machines, so the temperature can reach 130°. As an alternative solution, superheated steam is used, which is supplied at a pressure of up to 1 bar. When receiving water at the outlet, significant savings can be achieved by using low-temperature or secondary energy resources. These include waste incinerators, low-pressure steam from power plants, and thermal power plants.
A significant advantage of absorption chillers is the almost complete absence of moving parts, which is why the unit is highly reliable, because there are no spare parts that would become unusable.
But the main disadvantage is the worst weight and size parameters and high cost. This is true when compared with vapor compression devices, which sometimes leads consumers to make a choice not in their favor.
Vapor Compression Chiller Specifications
The water chiller can be a vapor compression chiller. A large class of such machines is based on this refrigeration cycle, as it is extremely popular. The main structural elements are: compressor, condenser, evaporator and flow regulator. The vaporized refrigerant is taken in by the compressor, which is designed to increase the pressure. In the condenser, the refrigerant cools and becomes condensed, becoming liquid. The condenser can be air or water, which will depend on the design of the system. At the outlet, the refrigerant has a liquid state at high pressure. The dimensions of the condenser are selected in such a way that the gas condenses inside. Therefore, the leaving water temperature is lower than the dew point.
The refrigerant in the liquid phase is injected into the flow controller, where the mixture pressure is reduced and a certain volume of liquid evaporates.
A mixture of liquid and vapor enters the evaporator. The first boils, takes heat from the medium, passes into a vapor state. The dimensions of the evaporator must be selected in such a way that the liquid evaporates inside. For this reason, the temperature of the vapor subsequently turns out to be higher than the boiling point. Thus, the refrigerant is overheated. Even the smallest droplets evaporate, and no liquid enters the compressor. During the operation of the machine, the refrigerant circulates in a closed circuit, while its state changes from liquid to vapor.
Air cooled chiller features
Water chillers, sometimes very expensive, can be air cooled. Such devices can be installed indoors, and air intake and exhaust is carried out through air ducts. Centrifugal units with high static pressure are used to move the air. The main advantage of this equipment is the possibility of organizing year-round use in cooling mode at any outside air temperature.
But there are also disadvantages, they are the need for large areas to accommodate the unit, among other things, you will additionally need to spend money on the ventilation network.
Reviews of the HUBER flow cooler SERIES DC
On sale you can find a flow water cooler of the above brand. It belongs to one of the varieties of liquid cooling thermostats. According to users, this equipment is specially designed for operation in undemanding and simple systems with circulating liquid. The unit is excellent for cooling tap water. The chiller can serve to reduce the lower threshold of the temperature range. You will be able to accurately control the process temperature when using this cooler in water bath conditions that are equipped with circulation adapters.
The entire system does not need to be replaced, only the addition of a flow cooler will be necessary to obtain a bath thermostat and cooling and heating functions. Such a water cooler has compact dimensions, which are limited to 190x250x360 mm. The temperature range can vary from 30 to 50°.
Characteristics of the network water sample chiller
The TekhnoInzhPromStroy network water cooler is designed to lower the temperature of the network water during sampling at heating points.
The cooled medium can reach 150°, while the cooled medium can reach 40° or less. The cooling medium is water from the cold water supply system. Height, diameter and side fittings are 380x76x160 mm. The equipment has a compact size and low weight, which is equal to 3.3 kg when empty. After filling with water, the weight increases to 4.5 kg. This network water sample cooler must be operated according to the instructions that the coolant valve must be opened before the coolant is supplied to the housing.
The next step is to shut off the water supply and close the cooling water tap. The medium supply valve opens after opening the cooling water tap. This must be done immediately until its temperature reaches the required level. As a rule, the temperature of the medium is approximately 40°, this can be easily achieved by using tap water as a cooling medium. The water sampling cooler should be operated with periodic checks of the operation of taps and valves, it is recommended that the technician clean them of dirt.
