Abstract
A solar collector particularly for receiving concentrated solar energy from a large parabolic reflector and which forms the evaporator of a heat pipe type heat transfer mechanism. The solar collector is formed from a pair of spherical shell portions which are joined at their perimeters such that they are nearly tangent at their joint. This configuration provides low mechanical stresses on the welded joint, making the structure resistant to creep failure. The inside surfaces of the solar collector are preferably covered with wire screens for the transport of liquid heat pipe working fluid. Various finenesses of mesh can be used. Preferably, a coarse mesh is in intimate contact with the inside surfaces of the collector to act as a transport medium with a finer mesh covering it. These mesh layers can be applied to surfaces of sheet metal blanks through sintering or other processes which are thereafter deformed to the desired shell configurations.
