主体である。Conventional technology and its problems Traditionally, solar heat collectors are made by attaching plates, fins, etc. to collect solar heat on the outside of a pipe through which the heat collecting medium, gas or liquid (hereinafter referred to as fluid), passes. The main structure is that heat is transferred from the inside of the pipe to the heat collecting medium fluid.

るという欠点がある。Such heat collectors are designed to reduce radiation loss, in which solar heat that is once absorbed through heat conduction parts such as plates or fins is re-dissipated into the atmosphere through radiation, and to increase the length of the pipe to increase the area for heat transfer to the fluid due to the small inner diameter of the pipe. This has the disadvantage of increasing the friction loss between the fluid and the inner wall of the pipe.

より上記欠点を解消したものである。Problems to be Solved by the Invention The present invention solves the above-mentioned various problems by implanting a large number of needles in a substrate, and disposing a light transmitting plate on the needle protruding surface side of the needle-like member made to protrude from the surface of the substrate by adhesion or bonding. By making the fluid of the heat collecting medium flow between the substrate surface and the light transmitting plate, and by aligning the solar heat collecting part and the part where the heat collecting medium flows to reduce the heat conduction part, the heat is absorbed once. This reduces the re-dissipation of solar heat due to radiation, increases the heat transfer area to the heat collecting medium between the needle surface and the substrate surface, and
The above-mentioned drawbacks have been solved by making the 100μ6 version of the car.
