Pressure reducing air sunning protecting all-glass vacuum heat pipe heat collection component

Abstract

The invention discloses a pressure reducing air sunning protecting all-glass vacuum heat pipe heat collection component, which is composed of a heat collection component and an air sunning protector placed in a vacuum insulation layer at the tail end of the heat collection component, wherein the air sunning protector is composed of a thermal force driving device connected with the heat end of the heat pipe in a heat transmission manner, and a heat transmission straight drum connected with the thermal force driving device in a transmission manner or manufactured together with the thermal force driving device into an integrality; the air sunning protector is provided with two steady states, namely an open heat conduction state and a closed insulation state, and the air sunning protector is in the open heat conduction state when the heat transmission straight drum protrudes out of the tail end of a cover glass pipe connected in a heat transmission manner, and the air sunning protector is in the closed insulation state is formed when the heat transmission straight drum retracts to the tail end of the cover glass pipe connected in a heat transmission manner; the thermal force driving device comprises a thermosensitive permanent magnet steel driving device, a bimetallic strip driving device, a memory alloy driving device and a diaphragm capsule driving device. pressure reducing air sunning protecting all-glass vacuum heat pipe heat collection component is characterized in that the heat transmission straight drum is directly connected with the bottom end of the heat end of the heat pipe directly or connected with the bottom end through a heat sink in low thermal resistance by adopting a one-dimensional sliding pair structure; and the shape of the outer end part coincides with that of the inner surface of the tail end of the cover glass pipe. The pressure reducing air sunning protecting all-glass vacuum heat pipe heat collection component ensure that the pressure inside the heat pipe is always at most twice as big as the atmospheric pressure by adopting a small power air sunning protector; and the normal work of the heat collection is not affected.

Description

technical field [0001] The invention relates to an all-glass vacuum heat pipe heat collecting element protected by decompression air drying. 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, les...

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
