[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] like Figures 1 to 3 As shown, a thin-walled tube connecting pipe structure for a heat exchanger includes: a main body 2 integrally formed by a thin-walled tube, the main body 2 has a circulation channel 21, the main body 2 has a first limiting section 22 and a second limiting section 23, the first limiting section 22 is connected to the second limiting section 23 through a transition portion 24, and the transition portion 24 gradually narrows from the first limiting section 22 toward the second limiting section 23; the second limiting section 23 has a pier ring structure 231 facing outward and wrapping around the main body 2.
[0025] In the present application, the second limiting section 23 of the pipe structure is directly inserted into the inlet and outlet holes of the heat exchanger, and the pier ring structure 231 can be against the shell of the heat exchanger, thereby limiting the insertion depth of the second limiting section 23. Subsequently, the copper pipe is directly inserted into the first limiting section 22. Due to the setting of the transition part 24, the copper pipe will be limited after being inserted into the transition part 24 and cannot be inserted further.
[0026] The main body 2 is directly formed in one piece with a thin-walled tube, which has higher processing efficiency and lower cost. The enterprise adopts this one-piece forming method, which greatly improves the production speed and reduces the production cost.
[0027] Specifically, the end of the upper limit section away from the lower limit section is provided with an outwardly facing flange 221. After the copper tube is inserted into the first limit section 22, a receiving groove can be formed between the copper tube and the flange 221, and solder can be conveniently filled between the copper tube and the inner wall of the circulation channel 21.
[0028] Specifically, the cross section of the first limiting section 22 is circular.
[0029] Specifically, the cross section of the second limiting section 23 is circular.
[0030] Specifically, the free end of the pier ring structure 231 facing the second limiting section 23 has a limiting plane 21321. When the pier ring structure 231 abuts against the heat exchanger, the limiting plane 21321 completely abuts against the outer surface of the heat exchanger, and a welding seal is subsequently achieved. The pier ring structure 231 is arranged around the second limiting section 23.
[0031] Specifically, the pier ring structure 231 has a first limiting portion 2311 and a second limiting portion 2312 , the first limiting portion 2311 and the second limiting portion 2312 abut against each other, and the limiting plane 21321 is located on the second limiting portion 2312 .
[0032] This design can ensure that there is no liquid-intake chamber inside the pier ring structure 231, thereby avoiding noise generated when the liquid flows.
[0033] Specifically, there is a distance a between the pier ring structure 231 and the free end of the second limiting section 23 .
[0034] The size of the interval a can determine the insertion depth of the second limiting section 23 .
[0035] Specifically, the outer diameter of the pier ring structure 231 is greater than the outer diameter of the second limiting section 23 .
[0036] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative position relationship and movement status of the components in a certain specific posture, as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.
[0037] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. At the same time, the meaning of "and / or" appearing in the full text is that it includes three schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0038] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0039] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
