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

Embodiment Construction

[0031] figure 1 with figure 2 An example of the present invention is given.

[0032] figure 1 with figure 2 Among them, in the vacuum insulation layer between the tail end of the glass tube 2 and the tail end of the inner glass tube 3 of an all-glass vacuum heat collection tube, four middle vacuum heat pipes are uniformly distributed along the circumferential direction of the annular vacuum heat insulation layer for heat collection. Components are decompressed and air-dried to protect the heat transfer channels. Form a vacuum heat collecting element with a middle sheet decompression air drying protector. The air protection heat transfer channel is composed of a heat dissipation patch 4 , a heat sink 5 , a thermal drive device 6 , and a middle sheet 7 connected to the thermal drive device 6 . The shape of the outer surface of the cooling patch 4 is consistent with the shape of the inner surface of the round end of the cover glass tube 2 and contains an inward flanging ...

Abstract

A vacuum heat collection element with a middle piece pressure-reducing air drying protector is formed by arranging a middle piece pressure-reducing air drying protector in a vacuum thermal insulating layer between the tail end of a shade glass tube of a full-glass vacuum heat collection pipe and the tail end of an inner glass tube, wherein the middle piece pressure-reducing air drying protector comprises more than one air drying protection heat transmission channel; the air drying protective heat transmission channel comprises a heat dissipation paster, a heat sink, a heat power driving component with an interface in heat transmission connection with the inner glass tube, and a middle piece rotationally connected with or produced integrally with the heat power driving component; the air drying protection heat transmission channel has two stable states, namely an open heat conduction state in which the middle piece is in heat transmission connection with the heat sink and the heat dissipation paster simultaneously, and a close heat insulation state in which the middle piece is not in heat transmission connection with the heat dissipation paster and the heat sink simultaneously. The vacuum heat collection element is characterized in that the heat dissipation paster comprises a low thermal resistance connection interface connected with the shade glass tube round end inner surface, and a heat transmission interface connected with the middle piece. The element ensures that the pressure of a 70-watt heat collection element does not surpass 2 barometric pressures by using 10-watt heat dissipation power, and is high in reliability.

Description

technical field [0001] The invention relates to a vacuum heat collecting element with a middle sheet decompression air drying protector. 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 glass heat pipe can be directly made into an absorption film, less h...
