Heat pipe of glass shell

Abstract

A heat pipe with a glass shell is composed of a glass shell, a heat-conducting working fluid, and the like. Its glass shell heat pipe is fully sealed by a glass tube head at one end, and then connected to a full glass tube cavity that is exhausted and filled with a heat-conducting working fluid tailpipe after being closed by a glass tube head at the other end. The heat-conducting working medium tailpipe is evacuated, filled with heat-conducting working medium, and then the glass is welded and sealed to form an all-glass circular tubular container. The heat-conducting working medium filled in the heat pipe of the glass shell has the characteristics of large vaporization enthalpy, good thermal conductivity and stable physical and chemical properties. The heat-conducting working medium is either water, an aqueous solution, or a liquid organic substance; the filling amount of the heat-conducting working medium in the heat pipe of the glass shell: the heat-conducting working medium corresponding to the saturated heat-conducting working medium vapor volume of the glass-shell heat pipe under the maximum rated working temperature and pressure steam quality. The heat-conducting working medium steam above the maximum rated working temperature and pressure is superheated steam, and the relationship between its corresponding temperature and pressure follows Charles' law in gas experiments.

Description

Technical field [0001] The invention relates to a heat pipe with a glass shell, which belongs to the field of heat exchange elements. Background technique [0002] At present, the known heat pipes are metal heat pipes, and for the recovery of low-temperature waste heat, metal heat pipes are still commonly used. However, with the economic development of our country, metal resources are increasingly scarce and the cost of use is increasing. However, metal heat pipes have many defects such as corrosion, fouling, poor heat transfer efficiency, and high cost. It is more limited in the heat exchange of highly corrosive chemical media, waste heat recovery of sea water, sewage, flue gas and other corrosive and polluted media. Contents of the invention [0003] In order to solve the common problems of conventional metal heat pipes such as corrosion, scaling, poor heat transfer efficiency, and high cost, a heat pipe with a glass shell was invented. While satisfying heat exchange,...
