Description

technical field [0001] The invention relates to an angle-adjustable superconducting flat solar heat collector, which belongs to the field of flat solar heat collectors. Background technique [0002] At present, in the solar heat collector industry, superconducting heat pipes are widely used, and the heat pipe vacuum tube solar heat collector is a typical example. A superconducting heat pipe is a high-performance heat transfer element that relies on the flow and phase change of the working medium (superconducting liquid) inside the heat pipe to transfer heat. As a high-efficiency heat transfer element, superconducting heat pipes have thousands or even tens of thousands of times the heat transfer capacity of copper rods of the same diameter. The use of superconducting heat pipes as heat transfer elements has improved many of the shortcomings of vacuum tube collectors, such as pressure-bearing operation, higher heat collection efficiency, avoiding fouling in vacuum tubes, and ...

Problems solved by technology

However, the improved vacuum tube collector still has many structural shortcomings: 1. The ability to resist external impact is poor, and the vacuum tube is easily damaged; 2. Although the use of superconducting heat tubes makes the heat collection efficiency per unit heat absorber area higher than that of ordinary flat plates Heat collector, but due to its relatively large volume, the heat collection efficiency per unit installation area is not as good as that of a flat plate heat collector; 3. It cannot be used as a building material and a perfect combination of building integration

These disadvantages are precisely the advantages of flat-panel solar collectors, but ordinary flat-panel collectors also have the following disadvantages: 1. The heat collection rate is slow and the heat transfer efficiency is not high; 2. The heat loss during heat conduction is large; 3. .The angle of the heat-absorbing plate core cannot be adjusted, and the installation is greatly restricted. The angle must be fixed by the installation bracket
