The top of the heat dissipation wall is formed with a plurality of heat dissipation holes. However, the technical scheme of the invention still cannot overcome the problem of slow temperature rise due to the existence of internal heat conduction oil, and the heat conduction oil generates huge internal pressure on the radiating fins, so that the requirements on the sealing welding process of the radiating fins are more severe, and the arrangement positions of the radiating holes cannot enhance convection among radiating parts, thereby influencing uniform temperature rise.
