Working medium high-position boosting pressure-reduction heat collection component for protecting all-glass vacuum heat pipe from stagnation

Abstract

A working medium high-position boosting pressure-reduction heat collection component for protecting an all-glass vacuum heat pipe from stagnation comprises a heat collection component and a boosting stagnation protector, and is characterized in that a heat transfer straight cylinder is connected with the hot end of a heat pipe at a low heat resistance by adopting a one-dimensional sliding pair; the outer end part of the heat transfer straight cylinder coincides with an inner surface of a tail end of a shield glass tube; a boosting heating power driving device comprises a bimetallic strip boosting part, temperature-sensitive permanent magnet steel and soft iron; the temperature-sensitive permanent magnet steel is connected with the heat pipe in low heat resistance; the soft iron is in transmission connection with the heat transfer straight cylinder; the bimetallic strip boosting part boosts the absorption and combination of a driving pair of the temperature-sensitive permanent magnet steel and the soft iron when the temperature-sensitive permanent magnet steel transforms from a magnetic loss state to a magnetic state; and the heat pipe comprises a sparse core mesh. According to the invention, the low power stagnation protector is adopted to ensure that the water vapor pressure inside the heat pipe is never larger than two times of barometric pressure; the sparse core mesh is arranged inside the heat pipe to shorten the starting time of the heat pipe to over 10 minutes from over 140 minutes, so that the time of heat collection can be increased by 1 hour everyday in winter; and the bimetallic strip boosting part gives full play to the advantage of large attractive force of the temperature-sensitive permanent magnet steel and the advantage of long pushing force distance of a bimetallic strip.

Description

technical field [0001] The invention relates to an all-glass vacuum heat pipe heat collecting element that is boosted by a working medium at a high position to boost decompression and 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 hea...

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
