Boosting pressure-reducing air-drying protecting eccentric heat pipe vacuum heat collecting element

Abstract

Disclosed is a boosting pressure-reducing air-drying protecting eccentric heat pipe vacuum heat collecting element which is formed by a bent eccentric heat pipe vacuum heat collecting element and a boosting air-drying protector. The boosting air-drying protector comprises a boosting heating power driving device and a straight heat conducting barrel. The boosting pressure-reducing air-drying protecting eccentric heat pipe vacuum heat collecting element is characterized in that the straight heat conducting barrel is connected with the bottom of heat ends of heat pipes directly or by utilizing one-dimensional mobile accessory structural low heat resistance via heat sink, the shape of the outer end portion of the straight heat conducting pipe is matched with the inner surfaces of covering glass pipe tail ends, when bimetal boosting portions of the boosting heat power driving device is changed from nonmagnetic to magnetic in thermosensitive permanent magnet steel, deformation is generated to push the thermosensitive permanent magnet steel soft iron driving pairs to be actuated, and the heat pipes comprise working medium absorbing stoppers which are used for lifting up the working medium so as to accelerate starting of the heat pipes. With a small-power air-drying protector, pressure of the heat pipes can be guaranteed to be less than 2Pa, and in winter, the starting time of the heat pipes can be shortened from 140 minutes to 20 minutes, and heat collecting time is prolonged by 1 hour for every day.

Description

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