Straight way type solar collector tube

Abstract

A straight way type solar collector tube, principally composed by assembly of inner metal tubes and connection of outer glass tubes, the assembly of inner metal tubes is welded or spliced together by hollow metal tubes and bowl component, tube connection component located in two ends of the hollow metal tube; two ends of the metal tubes assembly is provided with metal elastic components that is sticked with the outer glass tube jacketed outside of the hollow metal tube; surface of the metal elastic component is wavilness caused by metal stretching or molding, and its back surface is S-shape, its inner hole is welded or sticked onto the metal tube connection component of the inner metal tube assembly; two ends of the outer glass tube is inserted into external port of the metal elastic component and sticked by adhesive to implement permanent connection with the outer glass tube. The invention is provided with features of high heat utilization, accumulating no rabbish, difficult furring, strong compression ability, generating high-heat hot water or vapour.

Description

technical field [0001] The invention relates to a straight-through solar heat collecting tube, in particular to a solar vacuum heat collecting tube bonded and connected by metal and glass, and belongs to the technical field of solar energy utilization. technical background [0002] In order to achieve cleanliness, environmental protection, and reduce energy consumption, the use of solar heat collection to obtain hot water has achieved gratifying results. However, the existing solar heat collection tubes can only be made into blind tubes with an opening at one end because the inner and outer tubes are made of glass. Tubes, they cannot withstand higher air pressure, nor can they be connected in series, so they can only use solar heat collection to obtain hot water. In order to use solar energy for large-area heating to centralize hot water supply or generate steam for domestic heating, boiler replacement, refrigeration and power generation, the first condition to solve these p...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method to solve the problem of expansion and contraction of glass and metal due to their different expansion coefficients by changing the structure of the heat collecting tube, thereby realizing simple process, easy manufacture and high reliability. , and greatly improves the heat utilization rate, and can withstand high water pressure, and can be applied to straight-through solar collector tubes that require medium and high temperatures
