New description: [New technical field] This creation is about the tube row structure of heat exchangers, especially the heat exchange tube row structure formed by the combination of ^ and straight tubes. [Prior Art] According to the copper metal, which has high ductility and high heat transfer efficiency, the conventional heat exchange tube row 10 is automatically processed by a copper tube to form a j as shown in the figure: a plurality of bent portions U and Several straight pipe sections 12 are connected to form a body-formed structure. However, the price of copper pipes is more expensive than that of other metal pipes. Therefore, the above problems are improved. (4) The industry has developed non-rust or other gold. The pipe body is made into a bent pipe portion and a straight pipe portion, and then the argon-welded welding is added to the heat exchange pipe row structure of the Thai, or the stainless steel 2 metal material pipe body is bent into a body-shaped bending body by mechanically adding 1 Tube structure. ~, However, the 'argon welding process usually relies on manual welding quality and high labor costs; in addition, the above integration = control ^ H after the need to carry out galvanizing treatment by s body surface (four) into an antioxidant layer and improve heat transfer The internal pain of the tube body should be handled ^ 〃 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 抽 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管 管The body (4) is also finely swelled, and the cracking explosion is asked 4, and the inside of the pipe body cannot be expected to provide anti- _ effect due to the two confesions. When the pipe body used for heat collection or heat exchange is used, it can effectively transmit 3 M418276 heat, and the pipe wall is usually very thin. Therefore, the above-mentioned welded or integrally formed elbow heat exchange tube row structure, the tube thereof The structural strength of the body bend is low, and it is not easy to remove the scale inside the pipe; and when the composite pipe is combined with a relatively small number of straight pipes to form a pipe row structure, the thickness of the pipe wall is limited, and it is difficult to perform thread forming on the pipe body surface. Processing, it is not easy to make the elbow and the straight pipe directly screw-lock combination; for further improvement, although the joint structure is set between the pipe body and the pipe body, the assembly and fixing method is a simple pressing structure. Not only is the sealing effect poor, but the structural stability of the joint is low, especially the cost of the special joint is extremely high, and overall it does not meet the industry's requirement for cost reduction. Therefore, the conventional heat exchange tube row structure has problems in the manufacturing process or in actual use, and has room for improvement. [New content] In view of the above-mentioned usage problems, the creators of this case considered it necessary to design a heat exchange tube row structure which is easy to process and assemble while having high structural strength and heat transfer effect. The reason is that, in order to achieve the above purpose, the main purpose of the present invention is to provide a combination structure of heat exchange tubes, which is composed of a combination of a plurality of curved tubes and a plurality of straight tubes, and the combined structure is The straight pipe is joined and a stagnation ring is disposed at the joint, wherein: the two ends of the elbow are respectively expanded into a joint, and each of the joints is provided with a shoulder at the junction of the elbow body, and The opening end edge is radially extended toward the center of the elbow to be a retaining edge; M.418276 The outer diameter of the straight pipe body is smaller than the inner diameter of the elbow pipe body, and a flange is disposed at the end thereof. In the joint, the outer diameter of the flange is greater than the inner diameter of the elbow body and the inner diameter of the joint, and the straight tube is limited by the flange between the shoulder and the rim and is not separated from the bend. In the state, the joint of the two pipe bodies has the effect of being surely combined and structurally stable. Another object of the present invention is that the sling ring is sleeved on the surface of the straight pipe body, and the elastic pipe is placed in the joint port to be the rim, the shoulder portion and The flange is limited between the joint opening and the surface of the straight pipe, so as to seal the gap between the joints of the two pipes to prevent the fluid from leaking out of the pipe, and at the same time, the two pipes are more closely combined, thereby increasing the stability of the overall joint structure and strength. A further object of the present invention is that since the sling ring is disposed on either side of the straight pipe flange, the effect of the limit engagement with the bent pipe joint and the retaining edge is achieved, and the straight pipe is additionally A pressing member is disposed between the stagnation ring and the rim, and the pressing member is pressed against the straight pipe body for pressing the rim; thereby, the heat exchange tube provided by the creation is arranged The combined structure has the advantages of less combination limitation, high assembly convenience, and the use of a special joint to achieve a compact combination of components, and has the advantage of reducing the overall production cost.
