U-type tubular solar heat collector

A U-shaped pipe type solar energy collector relates to a dual-layer vacuum tube type solar energy collector, belonging to the solar energy utilization technical field, which comprises an inner and an outer glass blind tube which form a vacuum chamber therebetween, wherein the outer surface of the inner glass blind tube is provided with a solar energy absorbing membrane, a U-shaped metal heat conduction pipe is axially arranged in the inner glass blind tube and is connected with a plurality of heat transfer fins. The U-shaped pipe type solar energy collector is characterized in that each heat transfer fin is transversely penetrated outside the U-shaped metal heat conduction pipe. The utility model adopts the U-shaped metal heat conduction pipe to obtain high bearing water pressure and strong corrosion resistance, and connects a plurality of heat transfer fins which are transversely penetrated to the U-shaped metal heat conduction pipe to obtain high heat efficiency, low cost, simple production and simple installment. The U-shaped pipe type solar energy collector can be mounted at any angle, to fit buildings effectively.
