Abstract
A solar heat exchanger in which the manifolds are connected together using a threadless connection arrangement in which the end of one manifold tube carries at least two annular seals and the internal bore of the end of the adjacent manifold tube is cammed and when locked, the connection of the two manifolds is resistant to loosening when exposed to repeated thermal expansion and contraction cycles.
Claims11
A solar heating assembly for collecting solar radiation and using it to heat water, said assembly comprising an array of parallel tubes whose first ends are affixed to an inlet manifold assembly and whose second ends are affixed to an outlet manifold assembly, each said manifold assembly comprising tubular manifolds connected together end to end using a threadless connection arrangement in which:
- a male end of one said manifold is joined with a female end of an adjoining said manifold,
- tapered lugs on said male end are engaged with complementary tapered lugs on said female end, and
- tapered recesses on a locking ring accommodate all said tapered lugs and apply sealing pressure to said connection.
