Problems solved by technology

[0004] The invention aims to solve the problem of antifreeze crack failure of inorganic superconducting heat pipes
[0005] The method of the present invention which is different from the existing known technology is: add a special metal spring piece at the evaporation end of the heat pipe, use the gap between the metal spring piece and the tube wall to generate capillary action, absorb a certain amount of working medium liquid, and turn the working medium The mass liquid level is controlled in a cone-like body, which solves the problem of antifreeze crack failure of heat pipes

Embodiment Construction

[0010] exist figure 1 Among them, the gap block (2) is welded on the metal sheet (1), and then rolled into a multi-layer metal spring sheet (5) according to the pipe diameter of the heat pipe.

[0011] Such as figure 2 As shown, a special metal spring piece (5) is added in the heat pipe, and the gap between the metal spring pieces and between the spring piece and the heat pipe wall (4) is used to generate capillary action and absorb a certain amount of working fluid (3) , to precisely control the liquid level of the working fluid in the cone-like body, then vacuumize, seal and weld to complete the production of antifreeze inorganic superconducting heat pipes.

[0012] Force analysis of antifreeze inorganic superconducting heat pipe working fluid during crystallization in winter:

[0013] When the working medium immersed in the metal spring sheet crystallizes and expands in winter, since there is enough space in the middle of the metal spring sheet, it will not cause extrusi...

Abstract

An antifreeze inorganic superconductivity heat pipe is to solve the issue that a heat pipe used in a solar water heater cracks in the severe cold. A special metal spring lamination is mounted on the evaporation end of a heat pipe. Due to the space formed between the metal spring lamination and the pipe wall, a certain amount of working liquid is sucked up by capillarity, and the working liquid is limited within roughly cone-shaped space to solve the issue of pipe cracking in the severe cold.

Description

Technical field: [0001] The invention relates to the antifreeze problem of an inorganic superconducting heat pipe suitable for use in northern cold regions. Background technique: [0002] In today's tense global energy situation and climate warming, which seriously threaten economic development and people's life and health, all countries are seeking new energy alternative strategies in order to achieve sustainable development and gain an advantage in future development. Solar energy has become the focus of attention due to its obvious advantages such as cleanness, continuous flow, energy saving, and economic security. With the continuous strengthening of people's awareness of environmental protection, more and more consumers tend to choose solar water heaters, especially solar water heaters with auxiliary electric heating function mainly in the south. , can be used all year round. [0003] However, the use of water heaters in the north is not satisfactory. Due to the cold,...
