Embedded boosting straight cylinder vacuum heat collection pipe element pressure reduction stagnation protector

Abstract

An embedded boosting straight cylinder vacuum heat collection pipe element pressure reduction stagnation protector is formed by a boosting thermal driver and a heat transfer straight cylinder, and is characterized in that a heat radiation patch is provided with an interface in low resistance connection with the inner surface of round sealed end of a cover glass tube; the heat transfer straight cylinder can longitudinally move in the direction of the axial line of a heat collection element; the boosting thermal driver comprises a double-metal sheet boosting part, a block of thermal sensitive permanent magnetic steel and a block of soft iron; the soft iron is in transmission connection with the heat transfer straight cylinder; and the double-metal sheet boosting part deforms to help a boosting thermal sensitive permanent magnetic steel soft iron driver pair suck during the state of the thermal sensitive permanent magnetic steel is converted from demagnetized into magnetic. The problem that the soft iron is too far from the thermal permanent magnetic steel 8 to normally work, which is caused by thermal expansion and precision errors, is solved, as a result, the thermal permanent steel driver can more quickly and reliably operate. According to the invention, only the low-power stagnation protector can ensure that pressure of steam in the hot pipes is not greater than double atmospheric pressure always, and is high in reliability.

Description

technical field [0001] The invention relates to a decompression air-drying protector for a heat-collecting element of an embedded boosting straight tube 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 mad...

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
