Abstract

A vacuum heat tube conductive thermal insulator is a sealed tube chamber, filled with phase-shift medium, or filled with weight material. The sealed tube chamber filled with weight material is heavier than the water in same volume. The diameter of sealed tube chamber is smaller than the inner diameter of vacuum heat collecting tube chamber. The specific weight of weight material is higher than water. The sealed tube chamber is filled with water. Or the weight material contains some water. The invention is mounted at the bottom of glass vacuum heat collecting tube chamber, relative to the elastic metal support clamper. In sunlight, the energy adsorbed by the adsorption film is conducted to the invention to heat the medium. In night, the invention utilizes the reduced temperature and one-way conductivity of heat tube to condense the steam in the element to obtain vacuum.

Description

Technical field [0001] The invention relates to a vacuum heat-collecting tube heat conduction warmer, which belongs to the field of solar energy applications. Background technique [0002] At present, the free ends of the known solar vacuum heat collecting elements are all equipped with an elastic metal support card. This metal support card becomes the main way for the solar heat collecting element to dissipate heat at night, especially in the cold winter night, which greatly affects the solar energy collecting effect. The thermal insulation properties of the thermal elements reduce the thermal insulation performance of the solar water heater and greatly reduce the thermal efficiency. Invention content: [0003] In order to solve the problem of heat dissipation of the elastic metal support card of the solar vacuum heat collecting element, a heat conduction insulator for the vacuum heat collecting tube was invented to realize one-way heat conduction and heat preservation of...
