ABSTRACT:
The sides of a heat exchanger unit are joined with perimeter flanges which are folded one over the other and then crimped tightly in such fashion as to cause adjacent portions of the perimeter to extend at different angles in different planes resulting in a scissor action therebetween effective to securely clamp the heat exchanger sides together and form a leak-proof chamber.
