Claim 0:
1. A heat exchanger assembly, comprising:
an enclosure forming an open interior space receiving heat generating components, the enclosure comprising:
sidewalls surrounding the open interior space;
a cover portion positioned on a first end of the sidewalls; and
a bottom portion positioned on a second end of the sidewalls opposite the first end, the bottom portion comprising:
a bottom wall extending between the sidewalls,
a base tray defining a plurality of fluid channels in a fluid space extending outward from the bottom wall, the plurality of fluid channels extending between an inlet manifold area and an outlet manifold area for the flow of a heat exchange fluid,
engaging members forming a perimeter around the fluid space within the base tray,
a top plate positioned over the base tray to seal the fluid space from the open interior space, the top plate forming part of the bottom wall, the top plate having a first side defining a primary heat transfer area and a second side facing the base tray such that the plurality of fluid channels are defined between a bottom surface of the base tray and the second side of the top plate, openings in the top plate positioned and shaped to receive the engaging members of the base tray,
a plurality of ribs within fluid channels on each of an inlet side of the heat exchanger and an outlet side of the heat exchanger, and the ribs formed on a bottom surface of the base tray and extending from the bottom surface of the base tray toward the second side of the top plate, and
first sealing members positioned along the perimeter formed by the engaging members, second sealing members positioned on a top surface of one or more of the plurality of ribs and in contact with the second side of the top plate, and the first sealing members and second sealing members compressed by folding of the engaging members over the top plate to form a fluid-tight seal between the base tray and top plate,
wherein the top plate is comprised of a first thermally conductive material and the base tray is comprised of a second, non-thermally conductive material; and
the heat generating components positioned within the enclosure and on the bottom wall including the top plate.
