Novel leakage-proof vacuum tube solar heat collector

Abstract

The invention relates to a novel leakage-proof vacuum tube solar heat collector. The novel leakage-proof vacuum tube solar heat collector comprises a heat preservation device, a heat collection device and a fixing device. The heat collection device is integrally fixed through the fixing device and transmits heat into the heat preservation device to be stored and to supply the heat to the outside. The heat preservation device sequentially comprises a united collection box, a heat preservation box and a heat preservation box shell from the inside to the outside. The heat collection device comprises all-glass vacuum tubes, superconducting heat tubes and a reflector. One end of each superconducting heat tube is placed in the corresponding all-glass vacuum tube, and the other end of each superconducting heat tube is inserted into the corresponding inserting groove of the united collection box. The all-glass vacuum tubes are placed in installing holes of a frame body of the fixing device. According to the novel leakage-proof vacuum tube solar heat collector, the phenomena of water flowing, water leaking and scale forming inside the all-glass vacuum tubes are avoided, and the heat efficiency of the solar heat collector is stable; moreover, the superconducting heat tubes have the frost resisting performance and the anti-overheating performance, and thus the problems of high temperature under the no-load condition and freezing frost cracks in high-cold areas due to a solar heat collector manufactured through the prior art can be thoroughly solved; in addition, the novel leakage-proof vacuum tube solar heat collector is high in pressure-bearing capacity and stable in operation.

Description

technical field [0001] The invention relates to a novel leak-proof vacuum tube solar heat collector, which belongs to the field of solar water heating equipment. Background technique [0002] The glass vacuum tube solar collector has a history of more than 20 years, and the technology is relatively backward. The main disadvantages are that it is easily broken and the heat absorption efficiency is poor. Poor frost resistance, water leakage, explosive tubes, and a rupture of a vacuum tube will cause the entire row of solar vacuum tubes to be unusable, so the maintenance cost is also high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a novel leak-proof vacuum tube solar heat collector that does not leak water in the tube. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a novel leak-proof vacuum tube solar heat collector, which in...
