HEAT-EXCHANGING METAL PANEL

摘要

A heat exchange panel having a desired system of internal tubular passageways is described, wherein the internal passageways include opposed headers connected by connecting portions of said passageways extending therebetween. The headers define an angle of at least 91.degree. with respect to the direction of flow of heat exchange medium in the heat exchange panel. The headers are designed to provide uniform fluid distribution and to enable efficient drainage of fluid from the unit, including any entrapped gases.
