Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
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; wherein a 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.
Claim 2
Dependent Claim
110 words
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; wherein a 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.
Claim 3
Dependent Claim
24 words
A dissipation case for a power supplier of direct current according to claim 1 wherein said upper cover is made of cast aluminum alloy.
Claim 4
Dependent Claim
162 words
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; wherein a plurality of longitudinal guide walls integral to said base cover form a plurality of air passages with an end part communicating with a recess area for a fan and the other end part communicating with outside air through a plurality of ventilation openings located at an end wall of said base cover so that a plurality of heat sinks are formed and are in communication with said transistors; and a receiving chamber with thermal silicon rubber therein is provided on said base cover to receive said transformer.
