Introduction to heat pipe radiator

      The emergence of heat pipe has a history of decades. Heat pipe radiator is a technology that uses the property of absorbing / emitting heat in the process of phase change to cool. This technology was first introduced into notebook computers by IBM.

     The working principle of heat pipe is actually relatively simple. The heat pipe is divided into evaporation heating end and condensation end. When the heating end begins to heat, the liquid around the pipe wall will instantly vaporize and produce steam. At this time, the pressure of this part will increase, and the steam flow flows to the condensing end under the traction of pressure. After the steam flow reaches the condensing end, it is cooled and condensed into liquid, which also releases a lot of heat. Finally, it returns to the evaporation heating end with the help of capillary force and gravity to complete a cycle.

      For most people, the understanding of heat pipe radiator starts from computer CPU. In fact, heat pipe radiator is also widely used in industrial electronics. Many high-power devices of industrial electronics will use heat pipe radiator, such as IGBT module (IGBT heat pipe radiator).

      The heat transfer efficiency of the heat pipe is related to the structure, process and diameter. The diameter of the heat pipe has an obvious impact on the heat transfer. The larger the diameter, the better the effect. However, it is not just a large diameter that can produce a good product, which involves the combination, arrangement, combination mode and cost of the heat pipe.

   When designing heat pipe radiator solution for customers, Sinda thermal will start from all aspects of customers' requirements, develop and design according to the actual situation, and finally make high-performance heat pipe radiator.
