First Claim
Patent Images
1. A dissipation case for a power supplier of direct current comprising:
- an upper cover,a base cover which is made of cast aluminum alloy with an open surface closed by said upper cover to form an inner space,a printed circuit board which comprises a plurality of power transistors, a transformer and related wirings and is located in said inner space to convert alternating current into direct current along with a voltage drop;
whereina plurality of heat sinks integral to said base cover are in communication with said power transistors and a receiving chamber with thermal silicon rubber therein is provided on said base cover to receive said transformer.
