Claim 10:
11. A heat exchanger assembly, comprising:
an enclosure defining an open interior space, the enclosure comprising:
a bottom portion, comprising:
a bottom wall,
a base tray comprising a cooling medium flow path area extending outward from the bottom wall, the base tray comprising a plurality of fluid channels formed by a plurality of ribs extending from a base wall of the base tray, the plurality of fluid channels extending between an inlet manifold area and an outlet manifold area for the flow of a heat exchange fluid through the heat exchanger, a base tray peripheral flange area extending from and surrounding the cooling medium flow path area, the base wall of the base tray forming the bottommost wall of the heat exchanger and the base wall supporting the heat exchanger, a base tray sidewall extending between the base wall and a bottom wall, and
a top plate positioned on and supported by the base tray peripheral flange area and the ribs, the top plate sealing the cooling medium flow path area 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 for receiving one or more heat-generating components and a second side, opposite to the first side, for effecting a sealing relationship between the top plate and base tray peripheral flange area;

a sidewall with an end connected to the bottom wall, the sidewall extending away from the bottom wall and surrounding the bottom wall;
a cover portion positioned on an end of the sidewall distal from the bottom wall and in sealing relationship with the sidewall, the length of the sidewall forming the open interior space between the cover portion and the top plate, the cover portion having a sealing surface disposed in face-to-face sealing relationship with a peripheral flange of the sidewall;
the one or more heat generating components positioned within the enclosure and, positioned on and supported by the bottom wall including the top plate;
a first and a second fluid passage extending through the sidewall, extending through the bottom wall, and carrying fluid between an exterior of the heat exchanger and the cooling medium flow path area, the first and second fluid passages passing through the open interior space of the enclosure; and
engaging members form a perimeter around the cooling medium flow path area within the base tray, the engaging members passing through openings in the top plate, and folding of the engaging members over the top plate compresses sealing members positioned between the base tray and the top plate to form a fluid-tight seal between the base tray and the top plate.
