Combined structure of non-welded solar collector tube body

Abstract

The invention discloses a non-welding combined structure of a solar thermal collector tube body. The structure comprises a collecting tube, a tube bank and a penetrating-connecting sleeve, wherein the collecting tube comprises a tube wall and a containing space and is provided with a screw hole and a through hole, the screw hole does not penetrate through the tube wall, the through hole is located in the screw hole and communicated with the containing space, the penetrating-connecting sleeve comprises a tube column provided with a perforated hole, and the outer edge of the tube column is provided with a plurality of threads capable of being screwed in the screw hole; one end of the tube bank is provided with a ring piece abutting against the outer side of the through hole, the tube bank penetrates through the tube column, and the front end of the tube column abuts against the ring piece, wherein the tube bank is combined to the lateral side of the collecting tube due to the fact that the tube column is combined with the screw hole in a screwed mode, and the ring piece is extruded by the tube column to abut against the exterior of the through hole. Thus, the collecting tube and the tube bank are combined in the non-welding mode, and the assembling method is simplified.

Description

technical field [0001] The invention relates to a solar heat collector, in particular to a combination structure of a non-welded solar heat collector tube body. Background technique [0002] At present, in the application of solar radiant heat energy, solar collectors are relatively commercialized and economical products. The current structure design of solar collectors is as follows: figure 1 Shown; solar collector 1a includes a set of headers 10a and a plurality of row pipes 20a, these row pipes 20a are connected to the side of the set of headers 10a, and absorb solar radiation heat. When using the solar heat collector 1a, cold water flows in from one end of the header pipe 10a on one side, then flows through the row pipes 20a, and the water exchanges heat with the row pipes 20a, and then flows from the side header pipe 10a. The other end flows out, so as to collect the hot water after absorbing heat energy and make use of it. [0003] The header 10a of the aforemention...

Problems solved by technology

[0003] The header 10a of the aforementioned solar heat collector 1a is usually made of copper tubes, and its combination with 20a mostly adopts the traditional welding method. This welding combination method is not only complicated and time-consuming, it is not conducive to mass production, and there is also the possibility of leakage at the welding place It is quite cumbersome when heavy work is required, and subsequent maintenance is inconvenient, so it needs to be improved
