[0015] Specific implementation method

[0016] The following describes the present invention in detail with reference to the accompanying drawings: the present invention is mainly composed of an inner metal tube assembly and an outer glass tube; the inner metal tube assembly is composed of a hollow core inner metal tube 1, a bowl-shaped piece 2, and a pipe connection piece. 3 is integrated by welding, and then a metal elastic piece 7 is welded or bonded to the outer circle of the pipe connection piece 3. On the metal elastic piece 7 there is an exhaust pipe 8 for air extraction; the metal elastic piece 7 is a metal pull It is stretched or molded into a wavy surface, its rear end is formed into an S shape, and its inner hole is welded or glued to the metal pipe connector 3 of the inner metal pipe assembly.

[0017] The outer surface of the hollow inner metal tube 1 is attached with a heat-absorbing film layer 4 formed by a composite material including more than one metal element. T...

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...
