Characteristics of Huimao Thermoelectric 

Cooling Module  

    The cooling materials of Thermoelectric Cooling Module produced by Hui Mao Company are connected to the copper conductor tab by two shielding layers. Thus they can effectively avoid the diffusion of copper and other harmful elements, which enable Thermoelectric Cooling Modules to have longer use life. In addition, every cooling module is strictly tested and selected by the advanced instruments to guarantee its high quality. The life of Thermoelectric Cooling Module of Hui Mao Company can reach 300 thousand hours and more, and can stand the shock of the frequent change of current direction.

Operation under high temperature

    The Thermoelectric Cooling Module of Hui Mao Company adopts a series of new soldering materials, which are very different from the low melting point soldering materials used by other domestic factories. The highest temperature of these soldering materials can stand the temperature as high as 125℃, 150℃and 200 ℃. In addition, Hui Mao Company is striving to improve the Thermoelectric Cooling Module's performance and enlarge its apply range.

Perfect Moisture Protection

    Every Thermoelectric Cooling Module has been subject to moisture protection treatment, which is made in vacuum and with silicone coating. Thus it can effectively prevent water and moisture from entering the inside of Thermoelectric Cooling Module.

Various specifications

    Hui Mao Company has the tooling and equipment for producing various specifications of Thermoelectric Cooling Module, and has mature and advanced production technologies. We can produce various specifications of Thermoelectric Cooling Module with 7, 17,127 and 161 electric couples, with the area of electric element from 1x1, 1.4x 1.4, 2x2 to 4x4 square millimeters, and with the current ranging from 2A to 24A. In addition, Hui Mao Company can also produce other specifications of cooling module according to the special requirement of customers. Hui Mao Company is committed to develop the high power modules, in order to promote the application of thermoelectric cooling modules to wider fields. Hui Mao Company is now able to produce the modules with the power density that is two times higher than that of common modules, we have successfully developed and manufactured the double-stage high-power cooling modules with the temperature difference of more than 90℃, with the cooling power of tens of watts. And the modules with low internal resistance (0.03Ω min) it has developed are suitable for thermoelectric generation.
