Glass heat pipe with solid-liquid working medium package and manufacturing method thereof

Abstract

A glass heat tube with a solid-liquid working medium bag comprises a cover glass tube, an inner tube and the solid-liquid working medium bag, wherein the heat collecting end of the inner tube is sleeved in the cover glass tube, the condensation end of the inner tube extends out of the cover glass tube, a vacuum interlayer is arranged between the inner tube and the cover glass tube, a clamp is arranged between the heat collecting end of the cover glass tube and the inner tube to support the inner tube, and the solid-liquid working medium bag is arranged in the inner tube and is formed by a liquid working medium and a solid cavity wrapping the liquid working medium. A manufacture method of the glass heat tube comprises the following steps of (a) confirming the volume proportion of the solid-liquid working medium bag occupying the glass heat tube volume according to the volume of the glass heat tube cavity, a glass material and stress grade; (b) designing the small solid cavity, filling the liquid working medium into the solid cavity and sealing the solid cavity in a fusing mode to form the solid-liquid working medium bag; (c) adding the solid-liquid working medium bag into the inner tube cavity through an exhaust port of the condensation end and vacuumizing the inner tube of the glass heat tube, and sealing the exhaust port of the condensation end in the fusing mode in a vacuum state.

Description

technical field [0001] The invention relates to a glass heat pipe and a manufacturing method thereof, in particular to a glass heat pipe with a solid-liquid working medium bag and a manufacturing method thereof. Background technique [0002] The performance of double-layer coaxial all-glass vacuum solar collector tubes has approached the theoretical limit. As a new product, the technology of all-glass heat pipe vacuum solar collector tubes has gradually matured and has been introduced to the market. But there are two main problems that limit the development of the all-glass heat pipe vacuum solar heat collector: 1. The control method of the heat pipe liquid working medium generally adopts the direct infusion method, and the infusion efficiency and quality are low, which is easy to cause damage to the infusion equipment and requires equipment maintenance. The frequency is high; 2. Direct infusion makes the infusion accuracy difficult to grasp, which affects the performance an...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a glass heat pipe with a solid-liquid working medium bag and a manufacturing method thereof to solve the technical problems existing in the background art: the control mode of the liquid working medium of the all-glass heat pipe type vacuum solar collector tube generally adopts the direct perfusion method, and the perfusion The efficiency and quality are low, which is easy to cause damage to the perfusion equipment, and the frequency of equipment maintenance is high; direct perfusion makes perfusion accuracy difficult to grasp, which affects the performance and reliability of the all-glass heat pipe vacuum solar collector
