Home > ProductsHeat Exchange Solution

Well dissipating the heat from the hot side, and releasing cold from the cool surface of modules will maximize the thermoelectric cooling performance. That is why the heat exchanger is a very important part in thermoelectric applications. Currently, We provide our clients the following solutions at very competitive price:

1. Bonded Fin Heat Sink.

We offers total flexibility in the design and manufacturing of Bonded Fin Heat Sinks. Each of our products can be built to the specific needs of our customer. Aluminum bonded can dissipate two to three times more heat than conventional extruded heat sinks.

 
  • Lapped on request
  • Tailored production for client specific needs

 

2. Heat Pipe Solution.

Heat pipe is a kind of super thermal conductive device, which consists of a sealed container with a working fluid and wick. It has several hundred and even a thousand time thermal conductivity that silver or copper has. A heat pipe' is passive device, resulting in high reliability and long working time.

In the heat pipes, the heat is absorbed by working fluid in the evaporator section, generating vapor. The vapor will travel with very fast speed to the condenser section where slightly lower temperatures will causes the vapor to condense, releasing its latent heat. The condensed fluid is then flowed back to the evaporator by the capillary forces developed in the wick structure. This continuous cycle transfers large quantities of heat from one end to the other section with very little temperature difference.

A heat pipe's operation is passive being driven only by the heat that is transferred. This passive operation results in high reliability and long life.

Heat Pipe Working Diagram

Heat pipe features:
  • High thermal conductivity, transferring large quantity of heat within small temperature difference
  • Not moving parts and without external force in operation, hence, silent and reliable.
  • Light in weight, compact in construction and being variety of shapes and sizes
  • Quick thermal response
  • Ability to operate in extreme environments
  • Allows heat sink to be located away from heat source

 

This is a low working temperature range heat pipe that is designed for a 40mmx40mm size thermoelectric module's heat dissipating. It can dissipate up to150watts heat generated from the hot surface of thermoelectric module. It can be much better even than bonded fin heat sink on heat dissipating.

 

A good application example of heat pipe solution is shown in a 48 litre thermoelectric minibar in which the heat pipe is applied for both hot and cold heat exchangers. With the heat pipe, there is not any fans needed in the minibar. It has not any moving or vibration parts, hence, reliable and completely not any noise.
