The above-mentioned tube assembly 100 is applied to a temperature control apparatus as an example, that is, the tube assembly 100 is used for delivering a refrigerant gas, and the above-mentioned tube assembly 100 will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the tube assembly 100 includes a first tube 110 and a second tube 120, the first tube 110 includes a first tube 111 and a second tube 112, the first tube 111 and the second tube 112 are connected to each other, one end of the second tube 120 passes through the first tube 111 and the second tube 112 to be in interference fit, a first receiving gap 130 is formed between an inner wall of the first tube 111 and an outer wall of the second tube 120, in other words, an inner diameter of the first tube 111 is larger than an outer diameter of one end of the second tube 120 close to the first tube 110, so that the first tube 111 and the second tube 120 are in clearance fit, an inner diameter of the second tube 112 is slightly smaller than one end of the second tube 120 close to the first tube 110, so that the second tube 112 and the second tube 120 are in fit, and the first receiving gap 130 is used for receiving solder.
By forming the first receiving gap 130 between the inner wall of the first pipe section 111 and the outer wall of the second pipe body 120, when the first pipe body 110 and the second pipe body 120 are welded, the solder is first placed in the first receiving gap 130, and then the solder is heated and melted, the melted solder is adhered to the inner wall of the first pipe section 111 and the outer wall of the second pipe body 120, and the first pipe body 110 and the second pipe body 120 can be connected together after the solder is cooled and solidified. It can be seen that, by using the pipe assembly 100, the solder can be effectively prevented from entering the inside of the compressor 200 during the production process of the temperature control device, so that the operational reliability of the temperature control device can be effectively improved.
The inner port of the first receiving gap 130 refers to a port of the first receiving gap 130 located at a connection between the first pipe section 111 and the second pipe section 112.
It is understood that the first tube 110 may be made of copper material or steel material, and the second tube 120 may be made of copper material or steel material, and optionally, the bonding force between the steel material and the solder is lower than that of the copper material, and in order to improve the welding strength between the first tube 110 and the second tube 120, the first tube 110 and the second tube 120 are made of copper material.

In the process of exhausting or sucking the gas of the compressor 200, the copper pipe body 150 has low strength, so the pipe assembly 100 is easy to vibrate under the action of the airflow pulsation, and the steel pipe body 140 and the copper pipe body 150 are welded, so that the overall strength of the pipe assembly 100 can be effectively improved, and the vibration of the pipe assembly 100 generated in the process of exhausting or sucking the gas of the compressor 200 can be effectively reduced. On this basis, as mentioned earlier, the cohesion between steel and the solder is lower, leads to the welding strength of copper pipe body 150 and steel pipe body 140 to be lower, and this embodiment is through locating copper ring 160 cover earlier on steel pipe body 140 and weld as an organic wholely with steel pipe body 140 for copper ring 160 combines each other with steel pipe body 140 and forms the compound body of copper steel, welds copper pipe body 150 and copper ring 160 mutually again, thereby realizes the welding between copper product and the copper product, can effectively improve the welding strength between copper pipe body 150 and the above-mentioned compound body of copper steel like this.

The copper ring 160 is sleeved with the end of the steel pipe body 140 far away from the first pipe body 110 and is welded with the copper ring 160 into a whole, so that the copper ring 160 and the steel pipe body 140 are combined to form a copper-steel composite pipe body, and then the copper pipe body 150 and the copper ring 160 are welded together, so that welding between copper materials is realized, and the welding strength between the copper pipe body 150 and the copper-steel composite pipe body can be effectively improved.
In the above embodiment, please refer to fig. 4, an end edge of the copper ring 160 close to the first tube 110 is bent inward to form the positioning portion 161, in other words, a port of the copper ring 160 close to the first tube 110 is a contracted port, that is, an inner diameter of the port of the copper ring 160 close to the first tube 110 is gradually decreased toward a direction away from the copper tube 150, and the positioning portion 161 abuts against the copper tube 150.
Through inserting copper body 150 in copper ring 160 and leaning on with location portion 161 counterbalance, on the one hand, can realize carrying out axial positioning to copper body 150 to can effectively improve the axiality between copper body 150 and the compound body of above-mentioned copper steel, on the other hand, location portion 161 plays certain leading-in effect, is convenient for insert copper ring 160 in the steel body 140, thereby can effectively improve the production efficiency of pipe assembly 100.
In the above two embodiments, the welding manner between the copper ring 160 and the steel pipe body 140 includes, but is not limited to, a furnace brazing process, a high frequency brazing process, a flame brazing process, and a vacuum brazing process. Optionally, the copper ring 160 and the steel pipe body 140 are welded together by a furnace brazing process, and during the furnace brazing process, the copper ring 160 and the steel pipe body 140 can be heated simultaneously, so that the copper ring 160 and the steel pipe body 140 can be more stably combined together, and the overall strength of the pipe assembly 100 can be further improved.
In the above two embodiments, the steel tube 140 and the first tube 110 are sleeved and welded together.

(refer to the connection structure of the first tube 110 and the second tube 120 shown in FIG. 1 or FIG. 3.)
In the process, the steel pipe body 140 and the second pipe section 112 are in interference fit, so that the inner port of the second accommodating gap can be sealed, the solder cannot enter the steel pipe body 140, the solder can be effectively prevented from entering the compressor 200 in the production process of the temperature control equipment, and the working reliability of the temperature control equipment can be effectively improved.

In another specific example, the steel tube 140 includes a fourth tube (not shown) and a fifth tube (not shown), the first tube 110 passes through the fourth tube and is in interference fit with the fifth tube, a third receiving gap (not shown) is formed between an inner wall of the fourth tube and an outer wall of the first tube 110, in other words, an inner diameter of the fourth tube is larger than an outer diameter of an end of the first tube 110 close to the steel tube 140, so that the fourth tube is in clearance fit with the first tube 110, and an inner diameter of the fifth tube is slightly smaller than an end of the first tube 110 close to the steel tube 140, so that the fifth tube is in interference fit with the first tube 110, and the third receiving gap is used for receiving solder. (refer to the connection structure of the first tube 110 and the second tube 120 shown in FIG. 1 or FIG. 3.)
