Heat exchanger media frame

Claim 1

A corner frame construction for a heat exchanger of the type in which a plurality of substantially rectangular media layers are disposed within a framework having top and bottom plates joined by four corner members so that the edges of the media layers are exposed and define two substantially normal air flow paths, said corner construction comprising: an elongated L-shaped member having one end connected to the top plate and the other end connected to the bottom plate, said L-shaped member having a first leg extending substantially parallel to a first edge of the media layers and a second leg perpendicular to said first leg and extending substantially parallel to a second edge of the media layers, a first flange member connected to and extending the length of said first leg, said first flange extending inwardly toward said first media layer edge, a second flange member connected to and extending the length of said second leg, said second flange extending inwardly toward said second media edge, and a layer of flowable sealant disposed along the length of said L-shaped member and in contact with both of said first and second legs, both of said first and second media edges and both of said first and second flange members.
