Embedded level vacuum thermal pipe heat collection element pressure reduction stagnation protector

Abstract

An embedded level vacuum thermal pipe heat collection element pressure reduction stagnation protector is formed by controllable heat transfer channels arranged at the tail end of a vacuum heat collection element in a vacuum heat insulation layer, and each controllable heat transfer channel is formed by thermal sensitive permanent magnet steel, soft iron hot fins, transmission levels and connecting clamping springs. The embedded level vacuum heat pipe heat collection element pressure reduction stagnation protector is characterized in that the fixed sides of the soft iron hot fins are in low thermal resistance connection with the bottoms of the hot ends of hot pipes; the transmission levels are located above the thermal sensitive permanent magnetic steel and the free ends of the transmission levels are inserted below the movable sides of the soft iron hot fins; when the thermal sensitive permanent magnetic steel is magnetic, the transmission levels are attracted by the thermal sensitive permanent magnetic steel to lower and enable the movable sides of the soft iron hot fins to bend downwards and be in heat insulated connection with cover glass tubes; and when the thermal sensitive permanent magnetic steel is not magnetic, under the action of the own elastic force, the transmission levels are lifted to raise the movable sides of the soft iron hot fins to be in heating transfer connection with the cover glass tube, so as to achieve stagnation protection. According to the invention, only the low-power stagnation protector can ensure that pressure of the interiors of the hot pipes is not greater than double atmospheric pressure always, and cannot affect heat collection.

Description

technical field [0001] The invention relates to an embedded lever vacuum heat pipe heat collecting element 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, ...

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
