Tubular solar collector system
First Claim

1. A solar collector comprising:
- a manifold having an inlet and an outlet for the introduction of and removal from said manifold of a fluid, said manifold having a plurality of heat exchange members therein adapted to be in heat exchange relationship with a fluid introduced into said manifold;
a plurality of tubular solar collector members extending downwardly from and operably and detachably connected to said manifold heat exchange members such that a first fluid contained within said tubular solar collector member is circulated by thermosyphoning action in heat exchange relationship with said heat exchange member of the manifold to which said tubular member is connected when said tubular collector members are exposed to incident solar radiation whereby heat is transferred from said first fluid to said heat exchange members and to a second fluid introduced into said manifold and wherein said heat exchange members define a wall portion of said manifold thereby preventing the ingress of ambient atmosphere into said manifold when a tubular collector is detached.

Abstract
A tubular solar collector system is provided in which a heat absorbing fluid is contained within tubular solar collectors completely separate and independent from a fluid circulated through the manifold to which the tubular collectors are operably attached. The collectors extend downwardly from the generally horizontal manifold so that when the fluid within the tubular collector is heated by incident solar radiation it is circulated to a heat exchanger in the manifold by thermosyphoning action.

4. A solar energy collector apparatus comprising:
- a manifold having an inlet and outlet for the introduction of and removal from said manifold of a fluid;
a plurality of elongated, light-transparent, cylindrical first detachable tubes extending downwardly from said manifold, said tubes having a first end and a second end, and each of said cylindrical tubes being jacketed by a light transparent cylindrical second tube defining a space therebetween and having the pressure in said space at a reduced pressure, the first end of said first tube extending for a length greater than said jacket;
a third tube for fluid circulation located centrally within said first tube and spaced therefrom, said third tube being open at both ends;
said manifold having a plurality of heat exchange members adapted to receive said first end of said first tube in operable communication therewith, said heat exchange members adapted to be in heat exchange relationship with a fluid introduced into said manifold and defining a wall thereby preventing ingress of ambient atmosphere into said manifold when a first end of a first tube is detached from said heat exchange member;
a first fluid within said first tube whereby said first fluid will circulate through said first tube by thermosyphoning action upon being heated by incident solar radiation and will exchange said heat with said heat exchanger in said manifold whereby a second fluid introduced into said manifold is heated. - View Dependent Claims (5, 6)
