Boosting decompression empty-drying protecting wing plate heat pipe vacuum heat collecting element

Abstract

A boosting decompression empty-drying protecting wing plate heat pipe vacuum heat collecting element is composed of a wing plate heat pipe vacuum heat collecting element and a boosting empty-drying protector. The boosting empty-drying protector is formed by connecting a boosting heating power driving device with a heat transfer straight drum in a driving mode. The boosting decompression empty-drying protecting wing plate heat pipe vacuum heat collecting element is characterized in that the heat transfer straight drum is connected with the bottom end of a hot end of the heat pipe in a low-thermal-resistance mode through a one-dimensional moving pair structure. The shape of an outer end of the heat transfer straight drum is matched with that of an inner surface of the tail end of a cover glass tube. A boosting heating power driving device comprises a double-metal-plate boosting component, thermosensitive permanent magnet steel and soft iron. The soft iron is connected with the heat transfer straight drum in a driving mode. The double-metal-plate boosting component helps to boost a thermosensitive permanent magnet steel soft iron driving pair to be attracted when the thermosensitive permanent magnet steel is changed from being non-magnetic to magnetic. The advantages of the thermosensitive permanent magnet steel soft iron driving pair of being large in attraction force, good in uniformity and long in double-metal-plate thrust operation distance are fully developed. By adopting a small-power empty-drying protector, water steam pressure inside the heat pipe can not exceed 2 atmospheric pressures throughout.

Description

technical field [0001] The invention relates to a vacuum heat collecting element for boosting decompression air drying and protecting fin plate 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 abso...

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
