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

Embodiment Construction

[0038] figure 1 , figure 2 and image 3 An example of the present invention is given.

[0039] Figures 1 to 3 Among them, in the vacuum heat insulation layer between the end of the glass tube 2 and the end of the heat pipe 1 of the all-glass vacuum heat pipe heat collecting tube cover, an embedded straight vacuum heat pipe heat collecting element decompression and air drying protector is set to form a heat reducing Compressed air protects the all-glass vacuum heat pipe heat collecting element. The air drying protector is composed of a heat dissipation patch 4, a heat sink 5, a heat-sensitive permanent magnetic steel driving device 6 and a heat transfer cylinder 7. The shape of the outer surface of the cooling patch 4 matches the shape of the inner surface of the tail end of the cover glass tube 2 . The heat dissipation patch 4 has a thickness of 0.22 mm and a width of 40 mm. The heat dissipation patch 4 is pressed and pasted on the inner wall of the cover glass tube 2...

Abstract

A working medium high-position gathering pressure-reduction heat collection component for protecting an all-glass vacuum heat pipe from stagnation comprises an all-glass vacuum heat pipe heat collection component and a stagnation protector, wherein the stagnation protector is formed through the transmission connection of a heating power driving device and a heat transfer straight cylinder, and is characterized in that the heat transfer straight cylinder is connected with the hot end of a heat pipe directly or through a heat sink by adopting a one-dimensional sliding pair at a low heat resistance; the shape of the outer end part of the heat transfer straight cylinder coincides with that of an inner surface of a tail end of a shield glass tube; the inner of the hot end of the heat pipe comprises a sparse core mesh formed by a plurality of slim capillary liquid absorbing cores 2-10 mm in width; the sparse core mesh is pressed and pasted on the inner wall of the hot end of the heat pipe by the adoption of an elastic clamp spring; and the area of the sparse core mesh is less than 5 % of that of the inner wall of the hot end of the heat pipe . 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 the barometric pressure; and 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 of the original bare tube, so that the time of heat collection can be increased by 1 hour everyday in winter.

Description

technical field [0001] The invention relates to an all-glass vacuum heat pipe heat collecting element for high-level accumulation of working fluid and decompression air drying protection. 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 ca...
