Background

Heat dissipation is a critical issue in power electronics design. For a 48V BSG inverter, a heat sink is generally used for power devices (mosfets) to ensure heat dissipation efficiency, and the heat dissipation solution is also generally air cooling.

The heat dissipation plate has heat dissipation characteristics, the heat dissipation characteristics are generally composed of heat dissipation ribs, the shape of each heat dissipation rib is mainly rectangular or square, and the direction of a cooling pipe of each heat dissipation rib is inconsistent with the rotation direction of the fan due to the arrangement mode of the heat dissipation ribs. Therefore, the amount of heat carried away is not uniform due to the local nature of the heat sink. That is, some locations may be characterized by more heat, some locations may be characterized by less heat, and even some locations may not be characterized by any heat when the fan is operating.

In actual use, if the wafer is not properly positioned on the MOSFET to dissipate heat, it may cause the cooling system to malfunction. Thus, for a 48V BSG inverter system, the problems and consequences would be very severe if the mosfets did not dissipate heat well.
