Solar energy collector system having balanced heat-exchange fluid flow

摘要

A coupling used between headers of adjacent collectors 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. The coupling is formed with an internal baffle 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.
