Kleine, C A; Middleton, V L

A heat exchanger having a desired system of tubular passageways for a heat exchange medium defining opposed headers connected by connecting portions of said passageways extending therebetween. Said passageways have entry and exit portions extending from said headers to provide ingress and egress openings for said heat exchange medium, wherein said tubular passageways comprise a plurality of island-like distentions connected by a plurality of tubular channels passing therebetween. Said tubular channels are positioned with their longitudinal axes at an angle to both the longitudinal and transverse dimensions of said panel. Said distentions and tubular channels serve to enhance resistance to bending under mechanical stress and reduce the incidence of failure at fluid temperature near or at their freezing point.
