Abstract
A method of and apparatus for fabricating a solar collector panel including providing a thermal conductive, heat absorbing plate having a plurality of grooves therein, feeding discrete lengths of solder strips having transverse curvatures into said grooves, respectively, placing a tube assembly having a plurality of conduits into said grooves of said plate in superimposed relation on said solder strips, holding said loose assembly together, and heating the loose assembly to melt the solder and effect a thermal conductive bond between said tube assembly and said plate.
Claims7
Apparatus for producing a solar collector panel comprising:
- a conveyor for supporting a thin metallic, heat conductive sheet in a substantially horizontal plane, said sheet having a plurality of grooves formed therein in a predetermined pattern for receiving a tube assembly formed of conduits arranged in the same predetermined pattern, means for sequentially feeding strips of solder in one direction into said grooves of said sheet before placement of said conduits of said tube assembly therein, means for moving said feeding means transversely of said one direction, said sheet, said strips of solder and said tube assembly forming a loosely assembled unit, means advancing said conveyor for moving said loosely assembled unit in a horizontal path to a heating station, means for clamping said unit together at said heating station, and means for heating said unit to melt said solder strips and bond said tube assembly to said sheet.
