Abstract
Equipment having a source of substantial heat is provided with a ventilated housing and an electronic assembly which can be mounted between ventilating air inlet and outlet opening means in the housing. The electronic assembly includes a plurality of parallel spaced-apart plates of which at least one of each adjacent pair of plates has electronic circuitry mounted thereon, the size and configuration of the inlet and outlet opening means and the spacing between the adjacent pairs of plates being sufficient for the flow of adequate ventilating air for the cooling of electronic circuitry mounted on the plates. The electronic assembly may be assembled into an integral unit by means of unique support elements prior to being mounted in the ventilated housing.

In an apparatus having a source of substantial heat, electronic apparatus and a ventilated housing therefor comprising:
- a first housing wall portion having inlet opening means therein through which ventilating air may be admitted,
- a second housing wall portion having outlet opening means therein through which ventilating air may be discharged,
- an electronic assembly comprising a plurality of parallel spaced-apart plates of which at least one of each adjacent pair of plates has electronic circuitry mounted thereon, said electronic assembly comprising:
- a first plate,
- a second plate spaced from and substantially parallel to said first plate,
- a third plate spaced from and substantially parallel to said second plate on the side of said second plate opposite said first plate,
- a plurality of first support elements interposed between said first and second plates in abutment therewith to establish the spacing between said first and second plates,
- a plurality of second support elements interposed between said second and third plates in abutment therewith to establish the spacing between said second and third plates, each of said second support elements being aligned with a respective one of said first support elements,
- and a plurality of securing means each associated with and extending through at least a portion of a respective pair of said first and second support elements to interconnect said first, second and third plates into an integrated assembly,
- and mounting means for mounting said electronic assembly intermediate said inlet opening means and said outlet opening means such that electronic circuitry mounted on said plates may be cooled by air flowing between said parallel plates from said inlet opening means to said outlet opening means,
- the size and configuration of said inlet and outlet opening means and the spacing between adjacent plates being sufficient for the flow of adequate ventilating air for the cooling of electronic circuitry mounted on said plates.

In an apparatus having a source of substantial heat, electronic apparatus and a ventilated housing therefor comprising:
- a first housing wall portion having inlet opening means therein through which ventilating air may be admitted,
- a second housing wall portion having outlet opening means therein through which ventilating air may be discharged,
- an electronic assembly comprising a plurality of parallel spaced-apart plates of which at least one of each adjacent pair of plates has electronic circuitry mounted thereon and securing means interconnecting said plurality of plates into an integrated assembly,
- and mounting means for mounting said electronic assembly intermediate said inlet opening means and said outlet opening means such that electronic circuitry mounted on said plates may be cooled by air flowing between said parallel plates from said inlet opening means to said outlet opening means, said mounting means comprising securing means for fastening a first one only of said plates to a selected one of said first and second housing wall portions, the other of said wall portions having guide means cooperating with said first plate only for locating said electronic assembly in a fixed position relative thereto,
- the size and configuration of said inlet and outlet opening means and the spacing between adjacent plates being sufficient for the flow of adequate ventilating air for the cooling of electronic circuitry mounted on said plates.
