Embedded pressure reduction idle sunning protector for heat collecting element with heat fins and vacuum heat pipe

Abstract

An embedded pressure reduction idle sunning protector for a heat collecting element with heat fins and a vacuum heat pipe comprises a plurality of controllable heat transfer channels. The controllable heat transfer channels are arranged in a vacuum heat-insulation layer and comprise heat-sensitive permanent magnet steel, the soft iron heat fins and connecting clamp springs. The embedded pressure reduction idle sunning protector is characterized in that fixed edges of the soft iron heat fins are connected with tail ends of inner glass pipes or the bottom of a heat end of the heat pipe in a low heat resistance manner, and movable edges of the soft iron heat fins can move among inner side surfaces of covering glass pipes and outer surfaces of the inner glass pipes; the heat-sensitive permanent magnet steel is arranged below the movable edges of the soft iron heat fins and is covered by the soft iron heat fins; when the heat-sensitive permanent magnet steel is magnetized, the soft iron heat fins are attracted by the heat-sensitive permanent magnet steel and are bent downwardly, and the movable edges of the soft iron heat fins cannot be in heat transfer connection with the covering glass pipes; and when the heat-sensitive permanent magnet steel is demagnetized, the soft iron heat fins are curled up under the action of elastic force of the soft iron heat fins, and the movable edges of the soft iron heat fins are in heat transfer connection with the covering glass pipes. The embedded pressure reduction idle sunning protector has the advantages that the low-power sunning protector can guarantee that the pressure of steam inside the heat pipe is not higher than twice the atmospheric pressure all along, and normal operation of the heat collecting element is completely unaffected.

Description

technical field [0001] The invention relates to a decompression air-drying protector for heat-collecting elements of embedded heat-fin vacuum heat pipes. 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 absorpt...

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
