Abstract
A cabinet (1) for stowage of electronic printed circuit boards (2,3,4) for example, is adapted for permanent installation in a vehicle structure by allowing the boards to be readily removable. The cabinet can thus be readily cooled by both air and fluid jackets (10,13, and 13,12) which are permanently connected to different sources of cooling flow.
Claims10
A cabinet for electronic apparatus mounted on a plurality of board members having spaced edge regions adapted for thermal conduction, said cabinet being suitable for permanent mounting in a structure, and comprising:
- parallel spaced side walls and parallel spaced end walls forming an open mouthed cabinet;
- guide means extending transversely across the inner sides of said spaced side walls for slidably receiving and locating the edge regions of the board members when the latter are inserted through the open mouth of said cabinet, said guide means effecting a good thermal path between said side walls and the board members;
- intermediate wall means providing a first fluid cavity between it and said side walls, said intermediate wall means having inlet and outlet means for allowing a first fluid to flow through said first cavity for cooling purposes;
- and
- outer wall means providing a second fluid cavity between it and said intermediate wall means, said outer wall means having an inlet and outlet means for allowing a second fluid to flow through said second cavity for cooling purposes.
