Anti-frozen-heaving heat pipe using elastic material

Abstract

The invention relates to an anti-frozen-heaving heat pipe using an elastic material, which is capable of withstanding multiple times of freezing and thawing cycle without fracture. A structure of the heat pipe comprises: an elastic rod is placed in a liquid bath in an evaporation section of the heat pipe, wherein the material of the elastic rod has elastic property; the density of the material of the elastic rod is higher than that of water; and the contraction deformation of the elastic rod is more than or equal to the swell capacity of the water when the elastic rod performs solid-liquid phase change in the water. The heat pipe overcomes the defects that in the past, when the frozen heaving happens, a core heat transfer component of a heat pipe solar water heater, namely the heat pipe may have the phenomenon of pipe cracking to cause that the heat pipe has no effect and the whole solar water heater is damaged and cannot work normally. The heat pipe arranges the elastic rod on the evaporation section of the heat pipe from the angles of the structure the material mechanics; and the elasticity of the material of the elastic rod is used to absorb the swell capacity generated in the process of curing liquid in the liquid bath to protect the pipe wall of the heat pipe from being damaged and realize preventing the frozen heaving of the heat pipe. The heat pipe has the advantages of simple structure, quite good effect and high practical value.

Description

technical field [0001] The invention relates to a heat pipe or a thermosiphon, in particular to an anti-freeze expansion heat pipe using elastic material which can withstand multiple freeze-thaw cycles without rupture. technical background [0002] The technology of domestic solar water heating devices has been greatly developed, from all-glass vacuum tube solar water heaters to solar heat pipe water heating devices. The defect of the all-glass vacuum tube solar water heater is that the reliability of the system is relatively low. For example, if a glass tube of the collector is broken, the whole water heater will not work normally. The heat pipe hot water system basically solves the above problems and realizes continuous operation with high reliability. Even if a certain heat collecting pipe fails, it will not affect the operation of the whole water heater. [0003] Before the present invention, when there is no sunshine continuously in winter, especially when solar water ...

AI Technical Summary

Problems solved by technology

When frost heaving occurs, the heat pipe, the core heat transfer component of the heat pipe solar water heating device, may crack the pipe, resulting in failure of the heat pipe, causing the entire solar water heating device to be damaged and unable to work normally
