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 consists of more than one idle sunning protection heat transfer channels and is arranged in a vacuum heat-insulating layer at the tail end of a vacuum heat pipe heat collecting element. Each idle sunning protection heat transfer channel consists of a heat radiating paster, a heat sink, a heating power drive device provided with an interface in heat-transfer connection with a heat pipe or an inner glass pipe, and a middle piece in transmission connection with the heating power drive device or integrally manufactured with the heating power drive device. The embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector has two types of stable states, namely an opening heat-conducting state when the middle piece is in heat-transfer connection with the heat sink and the heat radiating paster at the same time, and a closed heat-insulating state when the middle piece is not in heat-transfer connection with the heat sink and the heat radiating paster at the same time. The embedded type straight-barrel vacuum heat pipe heat collecting element pressure-reducing idle sunning protector is characterized in that the heat radiating paster includes an interface connected with the inner surface of the bottom end position of a cover glass pipe round sealing end and an interface performing heat transfer with the middle piece. Water vapor pressure inside a 70-watt heat collecting element heat pipe can be ensured not to exceed two atmospheric pressures through one idle sunning protector with10-watt heat radiating power, and the reliability is high.

Description

technical field [0001] The invention relates to a decompression air-drying protector for a heat-collecting element of an embedded mid-chip vacuum heat pipe. 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 abso...

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
