Abstract

The invention provides a power semiconductor cooling module for an electric vehicle. The power semiconductor cooling module for an electric vehicle, according to one exemplary embodiment of the present invention, is electrically connected to a motor and comprises: a box-shaped housing unit having an inner space; a power element unit disposed in the inner space and electrically connected to a motor via at least one busbar; a heat dissipation unit disposed in the inner space so as to make contact with the power element unit in order to cool heat generated from the power element unit; and a heat backflow prevention member disposed so as to surround at least a portion of the total length of the busbar, and disposed so as to make contact with the heat dissipation unit.

Description

technical field [0001] The invention relates to a power semiconductor cooling module for an electric vehicle. Background technique [0002] The types of eco-friendly vehicles include hybrid electric vehicles (HEV), electric vehicles (EV), and plug-in hybrid electric vehicles (PHEV) that combine the advantages of both. [0003] This eco-friendly car is powered by an alternating current (AC) three-phase voltage to drive the motor. Accordingly, eco-friendly cars require inverters to convert the DC voltage provided by the high-voltage battery into AC (alternating current) three-phase voltage for driving the motor, in order to power the car's components such as headlights, wipers, pumps, and control boards. The components provide a voltage of 12V and require a low-voltage DC-DC converter (Low DC-DCConverter) to convert the high-voltage battery into a 12V low-voltage battery. These inverters and LDCs are collectively referred to as power conversion devices. [0004] The power c...
