Abstract
A panel having multiple tubular passages extending therethrough and fitted on each end with a fluid tight hollow header. Apertures through one side of the headers place the tubular passages in communication with the interior of the headers. Fluid pumped into one header flows through the tubular passages to the other header, exchanging heat with the environment surrounding the panel as it passes therethrough. The panels are formed to provide a flow restrictive feature at the ends of the through fluid passages so that substantial flow will exist in all passages in all panels in an array of panels. One method for obtaining a fluid tight bond between the headers and the panel involves a forming process utilizing a heated die applied to the panel ends, and a subsequent panel and header material melting process followed by imposing pressure contact between the formed panel ends and the headers to thereby effect a permanent bond or weld.
