ABSTRACT:
A plate type evaporator core can be brazed in one step, even with long refrigerant feed pipes in place, and without the need for separate support fixtures or clips. This is done by stamping selected ones of the stamped plates that make up the core with integral feed pipe support flanges, located so as to coincide spatially with the desired final locations of the attachment end point of the feed pipes. The end points are supported on the flanges in the braze oven, and maintained in their proper locations regardless of any heat sagging of the rest of the feed pipe along its length.
