Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A heat exchanger base for electrical apparatus comprising, a frame having contiguous front, back and end walls; a plate secured to the upper edge of said frame forming a top wall for supporting electrical apparatus; a bottom plate secured to the lower edge of said frame; radiator means including a shelf mounted within said frame between and extending substantially parallel to the top and bottom plates and a plurality of like heat-radiating fins supported on said shelf and extending between said front and backwalls, the bottom surface of said top plate engaging the top edges of said fins; and air inlet and outlet means provided in said base communicating with respective opposite front and back portions of said radiator means for causing heat generated by the apparatus to be conducted through the top wall and dissipated through said radiator means.
Claim 2
Dependent Claim
140 words
A heat exchanger base for electrical apparatus comprising, a frame having contiguous front, back and end walls; a plate secured to the upper edge of said frame forming a top wall for supporting electrical apparatus; a bottom plate secured to the lower edge of said frame; radiator means including a shelf mounted within said frame between and extending substantially parallel to the top and bottom plates and a plurality of like heat-radiating fins supported on said shelf and extending between said front and backwalls, the bottom surface of said top plate engaging the top edges of said fins; and air inlet and outlet means provided in said base communicating with respective opposite front and back portions of said radiator means for causing heat generated by the apparatus to be conducted through the top wall and dissipated through said radiator means.
Claim 3
Dependent Claim
33 words
A heat exchanger base according to claim 1, wherein a honeycomb structure is mounted within the frame between the end walls and top and bottom walls to enhance the rigidity of the base.
