Abstract

The invention relates to a solution for breakage of an all-glass vacuum through type solar heat absorbing tube due to difference in temperature. The solution is as follows: one or more sections of U-V-shaped screw thread glass tubes are additionally arranged on inside and outside smooth glass tubes to defuse temperature expansion stress of the inside and the outside smooth glass tubes and balance raising and reducing amount of difference in temperature of the inside and the outside glass tubes to avoid breakage. Compared with the prior art, the all-glass vacuum through type solar heat absorbing tube has the advantages that: 1, the problem of breakage of the all-glass vacuum through type solar heat absorbing tube is solved to fulfill the heat insulating effect which is the same as that the glass liner solar heat absorbing tube; 2, the difficult problem that the glass liner solar heat absorbing tubes can not be connected in series is solved, and the all-glass vacuum through type solar heat absorbing tubes can be connected in series randomly; 3, high heat at any required temperature can be obtained due to the serial connection of the all-glass vacuum through type solar heat absorbing tubes, and heat source is provided for high temperature carriers; and 4, the all-glass vacuum through type solar heat absorbing tube is a through tube and can be sleeved with high pressure metal inner tube to make special tube for inner focusing solar power stations.

Description

Technical field: [0001] The invention relates to a manufacturing process of a broken-proof all-glass vacuum through-type solar heat absorbing pipe. Background technique: [0002] At present, among the vacuum solar heat absorbing tubes, the bottle-type solar heat absorbing tube has been applied and developed, which solves the heat source of low-temperature hot water bathing, reduces the greenhouse effect, and saves energy. The solar heat absorbing tube is the only solution to the heat source, but the inner tube of the all-glass vacuum through-type solar heat absorbing tube does not have the same expansion space as the inner tube of the bottle-type solar vacuum heat-absorbing tube, and the full-glass vacuum through-type solar heat absorbing tube due to the temperature difference effect The breakage rate is 100%, and the idea of ​​the through-type solar heat absorbing tube cannot be assisted in its implementation. It has become a fantasy. How to solve the broken problem of the ...
