Flat plate solar heat collector

A collector for radiant heat energy is disclosed, containing a radiation-absorbing heat-conducting panel in thermal contact with a series of "riser" tubes, through which a working fluid flows, thereby carrying away the radiant heat incident on the panel and absorbed by the fluid. A pair of larger diameter "header" pipes are connected to opposite ends of the riser tubes, providing access for the working fluid to and from the risers, and conducting the fluid to the pump driving the fluid motion and to the thermal "load" or object desired to be heated. Each riser tube intersects and passes through the interior of each header pipe, and the short end of the riser tube emerging from the opposite side of the header pipe is sealed by means of a cap which may be removed to facilitate cleaning of the riser tubes. Fluid passes between the risers and headers through a series of "metering holes" which are drilled through the walls of the riser tubes and located in the interior of the header pipes. These metering holes are sufficiently small to ensure that the fluid flows uniformly through all risers in any panel position, thereby minimizing temperature gradients in the panel and providing maximum thermal efficiency. In an alternative version, the panel is built up around an obstacle by cutting out sections of the risers which would otherwise intersect the obstacle and connecting the truncated ends of the risers to a common pipe which circumscribes the obstacle. |

DETAILED DESCRIPTION The present invention is a solar heat collector which fulfills the objects and overcomes the limitations recited above.
Briefly, this collector consists of a radiant heat-absorbing panel, normally metal, which is traversed by and in thermal contact with a series of riser tubes through which a heat-carrying fluid flows, causing the panel to function as a heat exchanger, and a pair of header pipes connected to opposite ends of the riser tubes to provide for ingress and egress of this heat-carrying working fluid.
The header pipes transport the fluid to the thermal load or heat-absorbing object, and to the pump which drives the fluid, thence back to the riser tubes to complete the circuit.
The risers preferably consist of a large number of parallel, evenly spaced tubes, distributed extensively over the surface of the panel.
A novel feature of this invention resides in the manner in which the riser tubes are connected to the header pipes.
The risers intersect each header at right angles, or some other angle appropriate to the specific panel shape, and each riser, being smaller in diameter than the header pipe, passes entirely through the center of the header pipe and emerges into a short stub on the opposite side.
This stub is terminated by a cap which is easily removable to facilitate cleaning of the interior of the riser tubes.
"Metering holes" are located in the walls of the portions of the riser tubes lying inside the header pipes, and the fluid passes between the risers and headers through these holes.
The holes are small enough in diameter to constrict the flow sufficiently to ensure that the risers are entirely filled with fluid in any panel position, and that the flow is always uniform through all the risers.
A modified version of this invention is a solar heat collector wherein the panel described above includes one or more holes or indentations to enable the collector to fit around obstacles.
In this version, sections of the pattern of parallel riser tubes must be removed where these tubes encounter the boundary of a hole or indentation and would otherwise intersect an obstacle
