Transverse internal thread heat pipe of solar water heater

Abstract

The invention relates to a solar water heater, in particular to a transverse internal thread heat pipe of a solar water heater, which is composed of an evaporation section, a heat insulation section and a condensation section, wherein the heat insulation section is positioned between the evaporation section and the condensation section, the inner wall of a heat pipe case is provided with screw threads, a straight line channel and a silk screen, and working medium is arranged in the heat pipe case. Because of adopting the internal structure of the pipe case, the invention reduces resistance of liquid backflow when the heat pipe works, strengthens long-distance heat exchange effect of the heat pipe at small angle or transverse state, improves the heat transfer efficiency of the heat pipe, overcomes the defects of low power and installation singleness when the existing heat pipe transfers heat at small angle or transverse state in long distance and satisfies the requirements of high-power transmission.

Description

technical field [0001] The invention relates to a solar heat pipe, in particular to a horizontal internal thread heat pipe for a solar water heater. Background technique [0002] At present, the solar heat pipes used in the market are mainly thermosiphons, also called gravity heat pipes. There is no liquid-absorbing core in the thermosiphon tube, and the return of the working fluid from the condensation section to the evaporation section depends on the gravity of the working fluid itself. Therefore, the work of the thermosiphon tube has a certain directionality, and the evaporation section must be placed below the condensation section. The working fluid can return to the evaporation section by its own gravity. This also determines the installation method of the heat pipe, limits the use of the heat pipe, and limits the use. The horizontal heat pipes that have appeared on the market now overcome the installation limitations of thermosiphons, but due to their increased liqui...

This also determines the installation method of the heat pipe, which limits the use of the heat pipe and limits the use.

The horizontal heat pipes that have appeared on the market now overcome the installation limitations of thermosiphons, but due to their increased liquid filling volume or single, simple capillary structure, the heat pipe working medium has a large resistance to reflux or cannot return in time, making the heat pipe Can't conduct heat continuously or work efficiency is low, can't demand
