[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] The three-way pipe fitting 100 for air conditioner to be protected by the present application is applied to an air conditioner (not shown) to evenly divide the refrigerant flowing in the air conditioner from one path into two paths.

[0042] like Figure 1 , Figure 2 As shown, the three-way pipe fitting 100 for air conditioning provided in one embodiment of the present application includes a three-way main pipe 11, an inlet pipe 20 and two outlet pipes 30. The three-way main pipe 11 is set as an integrated pipe body structure. The inlet pipe 20 and the two outlet pipes 30 are assembled to the three-way main pipe 11 in a plug-in manner and are respectively connected to the three-way main pipe 11, and the inlet pipe 20 and the two outlet pipes 30 are respectively welded to the three-way main pipe 11; wherein, the medium introduced into the three-way main pipe 11 by the inlet pipe 20 can be discharged outward through the two outlet pipes 30. That is to say, the inlet pipe 20 and the two outlet pipes 30 in the three-way pipe fitting 100 for air conditioning of the present application can be first assembled to the three-way main pipe 11 of the integrated pipe body structure in a plug-in manner, and then the inlet pipe 20 and the two outlet pipes 30 are respectively welded to the three-way main pipe 11. Here, the inlet pipe 20, the two outlet pipes 30 and the three-way main pipe 11 can be welded by furnace brazing or autogenous welding.

[0043] As can be seen from the above, when the three-way pipe fitting 100 for air conditioner of the present application is produced and prepared, the three-way main pipe 11, the inlet pipe 20 and the two outlet pipes 30 can be prepared separately first, and then the inlet pipe 20 and the two outlet pipes 30 plugged into the three-way main pipe 11 are connected by welding, so that the three-way pipe fitting 100 for air conditioner avoids the development and use of molds in the overall production process, which can play a role in reducing production costs. It should be noted that when the three-way pipe fitting 100 for air conditioner of the present application is a non-standard small batch part, the three-way pipe fitting 100 for air conditioner with the above structure can greatly reduce production costs.

[0044] like Figures 1 to 3 As shown, in one embodiment, three flanged portions 110 are formed on the three-way main pipe 11, one of which is arranged corresponding to the inlet pipe 20, and the remaining two flanged portions 110 correspond to the two outlet pipes 30 one by one; and the inlet pipe 20 and the two outlet pipes 30 can be plugged and matched with the corresponding flanged portions 110. That is to say, in the three-way pipe fitting 100 for air conditioners of this embodiment, the inlet pipe 20 and the two outlet pipes 30 are specifically assembled to the flanged portion 110 of the three-way main pipe 11, so that it is convenient to assemble the inlet pipe 20 and the outlet pipe 30 to the three-way main pipe 11, and to increase the contact area when the inlet pipe 20 and the outlet pipe 30 are respectively welded to the three-way main pipe 11, which has the effect of improving the connection stability when the inlet pipe 20 and the outlet pipe 30 are respectively welded to the three-way main pipe 11. Here, the flanged portion 110 on the three-way main pipe 11 can be specifically processed on the three-way main pipe 11 using the existing flanged process.

[0045] It should be noted that the inlet pipe 20 and the two outlet pipes 30 are not limited to being plugged into and matched with the corresponding flanged portions 110 on the three-way main pipe 11. For those skilled in the art, three through holes (not shown) for inserting the inlet pipe 20 and the two outlet pipes 30 respectively can also be formed on the three-way main pipe 11 by laser drilling, and then the hole walls of the through holes can be welded to the corresponding inlet pipe 20 or the corresponding outlet pipe 30, which will not be elaborated here.

[0046] like Figure 1 , Figure 2 As shown, in one embodiment, the three-way main pipe 11 is provided with a stainless steel pipe, so that the three-way main pipe 11 can be prepared by cutting off the existing stainless steel pipe, and the three-way main pipe 11 can be made of local materials, which facilitates the preparation of the three-way main pipe 11.

[0047] like Figure 1 , Figure 2 As shown, in one embodiment, a cover 12 is respectively assembled at both ends of the three-way main pipe 11 by welding; wherein the cover 12 is at least partially inserted into the interior of the three-way main pipe 11. This not only facilitates the assembly of the cover 12 on the three-way main pipe 11, but also increases the contact area when the cover 12 and the three-way main pipe 11 are welded, and improves the connection strength when the cover 12 and the three-way main pipe 11 are welded. Here, the cover 12 is set as a stamping part, and a baffle 121 is formed on the cover 12. The baffle 121 is arranged on the outside of the three-way main pipe 11 and abuts against the three-way main pipe 11 to limit the insertion depth of the cover 12 in the three-way main pipe 11 and to limit the assembly between the cover 12 and the three-way main pipe 11, which can further facilitate the assembly of the cover 12 on the three-way main pipe 11. It should be noted that the above-mentioned two covers 12 and the three-way main pipe 11 can also be welded by furnace brazing or autogenous welding.

[0048] In one embodiment, the outer diameter of the inlet pipe 20 is smaller than the outer diameter of the three-way main pipe 11; and the outer diameter of the outlet pipe 30 is smaller than the outer diameter of the three-way main pipe 11, so that the three-way main pipe 11 has enough space to be plugged and matched with the inlet pipe 20 and the outlet pipe 30, so that the assembly between the inlet pipe 20 and the outlet pipe 30 and the three-way main pipe 11 can be facilitated.

[0049] In one embodiment, the minimum distance between the center line of the outlet pipe 30 and the upper end of the three-way main pipe 11 is greater than the outer diameter of the outlet pipe 30; and the minimum distance between the center line of the inlet pipe 20 and the upper end of the three-way main pipe 11 is greater than the outer diameter of the inlet pipe 20. In this way, it is convenient to process and form a structure for inserting the inlet pipe 20 and the outlet pipe 30 on the three-way main pipe 11, thereby facilitating the processing of the three-way pipe fitting 100 for air conditioners. Here, it is convenient to process and form the flange portion 110 on the three-way main pipe 11 of the three-way main pipe 11, and prevent the deformation of the part of the three-way main pipe 11 where the cover 12 is assembled.

[0050] In addition, it should be noted that the center lines of the two outlet pipes 30 are symmetrically arranged relative to the center line of the inlet pipe 20, and the minimum distance between the two outlet pipes 30 is greater than the inner diameter of the inlet pipe 20; and the inner diameters of the two outlet pipes 30 are equal to each other. In this way, the medium is introduced into the three-way main pipe 11 through the inlet pipe 20, and is distributed to the two outlet pipes 30 after passing through the buffer of the internal chamber of the three-way main pipe 11. The two outlet pipes 30 have the same inner diameter, so the flow rate of the medium discharged from the two outlet pipes 30 is the same. In this way, the effect of evenly distributing the flow rate is achieved.

[0051] like Figure 1 , Figure 2 As shown, in one embodiment, the inlet pipe 20 and the two outlet pipes 30 are both configured as stainless steel pipes, so that the inlet pipe 20 and the two outlet pipes 30 can be prepared by cutting off the existing stainless steel pipes, and the inlet pipe 20 and the two outlet pipes 30 can be made of local materials, which facilitates the preparation of the inlet pipe 20 and the outlet pipe 30.

[0052] In this embodiment, the inlet pipe 20 and the two outlet pipes 30 are respectively connected with copper sleeves 40 by welding, and the inlet pipe 20 and the two outlet pipes 30 can be welded with components (not shown) in the air conditioner through the corresponding copper sleeves 40, so that the three-way pipe fitting 100 for air conditioners can be used in the air conditioner for welding with components in the air conditioner. Here, the inlet pipe 20, the two outlet pipes 30 and the copper sleeves 40 can be welded by furnace brazing or high-frequency welding.

[0053] In this embodiment, the inlet pipe 20 and / or the outlet pipe 30 are plugged with the copper sleeve 40. Preferably, the inlet pipe 20 and the outlet pipe 30 are plugged with the copper sleeve 40 respectively, and the copper sleeve 40 is assembled on the corresponding inlet pipe 20 and the corresponding outlet pipe 30, so that the subsequent welding between the copper sleeve 40 and the corresponding inlet pipe 20 and the corresponding outlet pipe 30 can be facilitated. Here, the copper sleeve 40 can be firstly sleeved on the corresponding inlet pipe 20 and the corresponding outlet pipe 30, and then the part of the copper sleeve 40 located on the inlet pipe 20 or the outlet pipe 30 is shrinked by a tool to achieve the assembly limit between the copper sleeve 40 and the corresponding inlet pipe 20 or the corresponding outlet pipe 30. Of course, for those skilled in the art, the copper sleeve 40 can also be partially inserted into the corresponding inlet pipe 20 or the corresponding outlet pipe 30, and the copper sleeve 40 can be plugged with the corresponding inlet pipe 20 and the corresponding outlet pipe 30, which will not be elaborated here.

[0054] In summary, the welding between the three-way main pipe 11 and the two sealing covers 12 in the three-way pipe fitting 100 for air conditioning of the present application, the welding between the inlet pipe 20 and the two outlet pipes 30 and the three-way main pipe 11 respectively, and the welding between the copper sleeve 40 and the corresponding inlet pipe 20 and the two outlet pipes 30 can be carried out simultaneously in a brazing furnace. In this way, the overall production and preparation of the three-way pipe fitting 100 for air conditioning can be further facilitated, which has the effect of reducing production costs and reducing costs.
