Claim 1
Independent Claim
133 words
In a cooling assembly including a heat generating electric part having leads, a heat conductive block mounting said heat generating electric part, and a heat pipe attached to said heat conductive block for radiating the heat from said heat generating electric part to the air through said heat conductive block, the improvement in which said heatconductive block comprises a thickened portion attached to said heat pipe, and a thinned portion formed contiguously to said thickened portion, said heat generating electric part is mounted on said heat-conductive block so that at least one part of said heat generating electric part extends on the outer surface of said thinned portion, and a connector is secured to the inner surface of said thinned portion and is connected to said leads of the heat generating electric part.
