CN-122002759-A - Power transmission module

Abstract

The invention designs a power transmission module. The power transmission module comprises a first bus bar and a second bus bar arranged opposite to the first bus bar. The heat dissipation structure is arranged between the two bus bars or outside the bus bars so as to dissipate heat of the bus bars. In an embodiment, the heat dissipation structure is disposed between the two bus bars, so that a single heat dissipation structure can be used to dissipate heat from the two bus bars at the same time, thereby reducing the cost of the heat dissipation structure. In addition, the insulating member may be disposed between the two bus bars and/or between the bus bars and the heat dissipation structure to achieve electrical insulation.
