SOLAR ENERGY COLLECTOR SYSTEM

摘要

A coupling 45 used between headers of adjacent collectors 17 in an array of solar collectors of the liquid heat- exchange type to balance the flow of heat exchange fluid through the absorber of each collector is formed with an internal baffle 52 in which an orifice of predetermined area is defined dependent on its position in the array. The coupling may also be used to vent entrapped air from the headers and to drain liquid from them.
