ABSTRACT:
The edge seal mechanism of the present invention may be used in connection with clamshell or other formed sheet metal heat exchanger apparatus of the kind utilized for directing hot flue gases into a defined combustion chamber and into various forms of flue passes for radiation from such heat exchanger such combustion chamber. The improved edge seal structure for a clamshell heat exchanger of the present invention includes a first plate flange portion, around which a second flange plate portion is wrapped to define a channel for disposition of the first plate flange portion therebetween. The seal between the first and second flange portion is further formed and stabilized by means of a lateral bend in the first and second flange portions, with such lateral bend being in the direction of and toward the terminal portion of the second plate flange in order to secure maintenance of the seal between the first and second plate flange portions.
