Embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector

Abstract

An embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector comprises a heating power drive device and a heat transfer straight barrel and is arranged in a vacuum heat-insulating layer at the tail end of a vacuum heat pipe heat collecting element. The idle sunning protector has two types of stable states, namely an opening heat-conducting state when the heat transfer straight barrel extends out of the tail end of a heat transfer connecting cover glass pipe, and a closed heat-insulating state when the heat transfer straight barrel retracts from the tail end of the heat transfer connecting cover glass pipe. The heating power drive device comprises a thermo-sensitive permanent magnet steel drive device, a double-metal-piece drive device, a memory alloy drive device and a capsule drive device. The embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector is characterized in that the heat transfer straight barrel is connected with the bottom end position of the heat end of an inner glass pipe or a heat pipe through a one-dimensional sliding pair resistor and can move horizontally. The outer end portion of the heat transfer straight barrel is matched with the inner surface of the tail end of the cover glass pipe in shape. The water vapor pressure inside the heat pipe can be ensured not to exceed two atmospheric pressures through one small-power idle sunning protector, and the reliability is high.

Description

Technical field [0001] The invention relates to an embedded straight-tube vacuum heat pipe heat-collecting element decompression air-sun protector. Background technique [0002] The vacuum heat collection tube is provided with a vacuum heat insulation layer between the cover glass tube and the inner glass tube, and can be used to manufacture vacuum solar water heaters that can provide domestic hot water in winter. Solar water heaters made of heat pipe vacuum collector tubes have the advantages of high energy efficiency ratio without water in the tube, compliance with sanitary drinking water standards, and single tube damage. therefore. Solar vacuum heat pipe water heaters without water inside the tube will likely occupy more and more market shares. [0003] The use of an integrated glass heat pipe has the advantages of being able to be fused with the cover glass pipe, the surface of the glass heat pipe can be directly made of an absorption film, there are few heat transfer links,...

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
