Boost decompression air drying protection all-glass vacuum heat pipe solar heat collection device

Abstract

A boosted pressure-reduced air-drying protecting full-glass vacuum heat-pipe solar collector device consists of a high-grade working medium boosted pressure-reduced air-drying protecting full-glass vacuum heat-pipe collector element, a heat-insulating water tank and a tail box, wherein the high-grade working medium boosted pressure-reduced air-drying protecting full-glass vacuum heat-pipe collector element is provided with a boosted air-drying protector inside a heat collection element vacuum heat-insulating layer; the boosted air-drying protector is formed through transmission connection of a boosted thermal driving component with a heat-transferring straight barrel; the boosted pressure-reduced air-drying protecting full-glass vacuum heat-pipe solar collector device is characterized in that the heat-transferring straight barrel is in low thermal resistance connection with the bottom end of a hot end of a heat pipe by using a one-dimensional moving pair structure; a boosted thermal driving component comprises a bimetal boosting component, heat-sensitive permanent magnetic steel and soft iron; the bimetal boosting component helps to drive the heat-sensitive permanent magnetic steel and the soft iron driving pair to attract each other when the heat-sensitive permanent magnetic steel is changed from a magnetic loss state to a magnetic state; and the heat pipe comprises a sparse core network. Through a small-power air-drying protector, the pressure inside the heat pipe can be ensured to not exceed 2 atmospheric pressures; and through the sparse core network, the startup time of the heat pipe is shortened from more than 140 minutes to more than 10 minutes, so that in winter, the heat collecting time every day is 1 hour longer.

Description

technical field [0001] The invention relates to an all-glass vacuum heat pipe solar heat collection device for boosting 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 can be directly made into an ...

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
