Abstract
A heat exchanger includes first and second plates between which a fluid flow passage is defined, through-holes defining inlet and outlet ports, and through fittings having first and second segments. Each segment includes a tube portion extending through one of the holes and a flange portion located inside the fluid flow passage. The flange portion of each segment has opposed first and second surfaces, the first surface joined to the inner surface of one of the plates in a fluid-tight manner. The second surfaces of both segments face each other, and at least second surface has one or more channels providing fluid flow from the hollow interior to the fluid flow passage. The second surfaces of the segments are in contact or closely apart from one another, the flange portions of the first and second segments providing support for the first and second plates in the area surrounding the ports.
