[0019] Specifically, in this embodiment, both the cold plate cover 2 and the cold plate main body 1 are made of aluminum alloy with good thermal conductivity. The cold plate main body 1 and the cold plate cover 2 are connected together by welding. The cold plate cover 2 is in a serpentine shape and is a thin plate part; a cooling flow channel 11 (cooling medium flows inside, including fuel, water liquid, etc.) is provided in the middle of the cold plate main body 1, and its shape is also serpentine. The serpentine turning points are all rounded corners to reduce the flow resistance of the liquid oil or water in the cavity. A plurality of ribs 12 are provided in the cooling flow channel 11 of the cold plate main body 1. The mixing of the liquid between the sub-flow channels formed by the cooling flow channel 11 being divided by the ribs 12 balances the temperature of the liquid at each position, making the liquid temperature uniform.
