Description

technical field [0001] The invention relates to a superconducting flat solar heat collector, which belongs to the field of flat solar heat collectors. Background technique [0002] At present, all-glass vacuum tubes or heat pipe vacuum tube solar water heaters have been widely used in the market, and there is also a small market share of flat-panel solar water heaters. However, under the current situation, because the flat-plate solar collector has many advantages that the vacuum tube cannot match, the application prospect of the flat-plate collector is very broad. Of course, the heat pipe vacuum tube collector also has its advantages, that is, the application of superconducting heat pipes, which can conduct heat efficiently, thereby improving the heat collection efficiency. 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.
