Heat pipe heatsink applications in IGBT module

    IGBT is not only a very important high-power device, but also the core device of energy conversion and transmission. In the field of power electronic devices, its importance is equivalent to "CPU". At the same time, IGBT is also a national strategic emerging industry, which is widely used in rail transit, smart grid, aerospace, electric vehicles and new energy equipment.

    The IGBT module of power electronic equipment has the characteristics of high power, high heat flux and compact structure. The ordinary air cooling heatsink can only be used for small heat flux. When using liquid cooling for heat dissipation, the conductivity of water should be considered. The deionization system with purification function should be used for ion exchange, which will increase fault nodes, liquid cooling is not conducive to improving safety, and there are problems of regular maintenance.

      The heat pipe heatsink can evenly transfer the heat of the substrate to the heat dissipation fins, which can effectively solve the heat dissipation problem of high heat flux. It has high efficiency, compact structure and no moving parts, and can truly realize maintenance free. Therefore, IGBT heat pipe heatsink has been widely recognized by users in the industry.
