Severe environment enclosure with thermal heat sink and EMI protection

A chassis construction incorporating a plurality of circuit cards and a power supply comprising:

• a top cover, bottom cover, a pair of side plates and a pair of end plates secured together to form an airtight seal along all abutting edges;
• a backplane fixed to one of said top and bottom covers, said backplane mounting a plurality of connectors for electrical connection with mating connectors along a first edge of each of said plurality of circuit cards;
• mounting grooves for receiving second, third and fourth edges of each of said plurality of circuit cards;
• and
• an internal partition separating said plurality of circuit cards from said power supply;
• wherein at least said pair of said plates are provided with a plurality of exterior cooling fins;
• and
• wherein said internal partition is rigidly fastened to said power supply and said pair of side plates to thereby provide a heat sink for said power supply.

A severe environment enclosure comprising:

• a first area supporting a plurality of computer components;
• a second area separated from said first area by an internal partition, said internal partition at least partially supporting a power supply;
• first means including said internal partition for rigidly mounting said plurality of computer components in three orthogonal directions within said first area;
• and
• integral heat transfer means including said internal partition for carrying heat form said power supply out of said enclosure.

A severe environment enclosure for computer components and an associated power supply, said enclosure comprising top and bottom covers, a pair of side plates and a pair of end plates;

• an interior partition extending between said pair of side plates to form a component support area and a power supply support area;
• a plurality of computer components mounted within said component support area and a power supply mounted within said power supply area;
• said partition partially supporting both said computer components and said power supply;
• and a backplane extending between said pair of end plates in said component support area and said power supply support area, said backplane rigidly fastened to at least one of said end plates, both of said pair of side plates, said bottom cover and said interior partition.
