Embedded booster mid-chip vacuum heat pipe heat collector element decompression air drying protector

Abstract

An embedded pressure reduction idle sunning protector for a heat collecting element with middle boosting sheets and a vacuum heat pipe comprises sunning protection heat transfer channels and is placed in a temperature vacuum heat-insulation layer of the heat collecting element. The heat transfer channels comprise radiating patches, heat absorbing parts, heat-sensitive permanent magnet steel driving devices and the middle sheets; and each sunning protection heat transfer channel has two stable states including a starting heat-conduction state and a closing heat-insulation state, and the middle sheets are synchronously or asynchronously in heat transfer connection with the heat absorbing parts and the radiating patches in the starting heat-conduction states or the closing heat-insulation states. The embedded pressure reduction idle sunning protector is characterized in that the radiating patches are provided with heat transfer interfaces arranged among the inner surface of a circular sealed end of a covering glass pipe and the middle sheets, the heat-sensitive permanent magnet steel driving devices comprise heat-sensitive permanent magnet steel and soft iron driving pairs and bimetal sheet boosting components; and the bimetal sheet boosting components deform to assist in pushing the permanent magnet steel and soft iron driving pairs to be actuated in a cooling procedure when heat-sensitive permanent magnet steel in a demagnetized state is switched into a magnetized state. The embedded pressure reduction idle sunning protector has the advantages that the low-power heat transfer channels can guarantee that the pressure of steam in the heat pipe is not higher than twice the atmospheric pressure during idle sunning, and the embedded pressure reduction idle sunning protector is high in reliability.

Description

technical field [0001] The invention relates to a decompression and air-drying protector for a heat-collecting element of a heat-collecting element of a vacuum heat pipe embedded in an embedded booster. Background technique [0002] The vacuum heat collecting tube is provided with a vacuum heat insulation layer between its cover glass tube and the inner glass tube, which can manufacture a vacuum solar water heater that can also provide domestic hot water in winter. The solar water heater made of heat pipe vacuum heat collecting tube has the advantages of high energy efficiency ratio without water in the tube, conforms to the sanitary drinking water standard, and can work as usual if a single tube is damaged. therefore. The solar vacuum heat pipe water heater without water in the pipe will likely occupy more and more market share. [0003] The use of an integrated glass heat pipe has the advantages of being melted and sealed with the cover glass tube, the surface of the gla...

Problems solved by technology

Since this patent is not specifically aimed at the heat-collecting elements of gravity heat pipes, it is not very targeted; the bimetal sheet thermal energy conversion drive used in it is originally not consistent with the product, and has the ability to return to its original shape after repeated heat deformation It will be reduced again, and the operating point setting, control variable input, comparison, energy conversion and energy supply and execution functions related to the control system undertaken by it are far from being able to work normally and effectively due to the impact on the accuracy of the possible 20-year design of the heat collecting element. life
