Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] In this application, the term "exemplary" is used to mean "serving as an example, illustration, or illustration." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The term "and / or" includes any and all combinations of one or more of the associated listed items.

[0024] This application provides a shunt 100, such as... Figures 1-3 As shown, the flow divider 100 includes an inlet channel 110, a jet channel 120, and a flow divider 130. The jet channel 120 gradually narrows in the direction of fluid flow (i.e., the orifice diameter of the jet channel 120 gradually decreases along the direction of fluid flow). The wide end of the jet channel 120 is connected to the inlet channel 110, and the narrow end of the jet channel 120 is connected to the flow divider 130.

[0025] The flow divider 100 provided in this application embodiment sets the jet channel 120 to be narrower in the fluid direction. The wide end of the jet channel 120 is connected to the inlet channel 110, and the narrow end of the jet channel 120 is connected to the flow divider channel 130. When the refrigerant fluid entering from the inlet channel 110 flows through the jet channel 120, the jet channel 120, which is narrower in the fluid direction, increases the flow rate of the refrigerant fluid and intensifies the mixing of the gas and liquid phases, thereby making the gas and liquid phases uniformly mixed.

[0026] Optionally, the length L of the jet channel 120 is 5mm to 10mm. Specifically, the "length of the jet channel 120" refers to the vertical distance between the wide end face and the narrow end face of the jet channel 120. For example, the length L of the jet channel 120 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm or any range between two values, and can be set according to actual needs.

[0027] Optionally, the cone angle of the jet channel 120 is 10° to 32°. For example, the cone angle of the jet channel 120 can be 10°, 12°, 15°, 17°, 20°, 22°, 25°, 27°, 30°, 32° or any range between two values, and can be set according to actual needs.

[0028] In some embodiments of this application, such as Figure 2 As shown, the distributor 100 also includes a transition channel 140, which gradually widens in the fluid flow direction. The narrow end of the transition channel 140 connects to the wide end of the jet channel 120, and the wide end of the transition channel 140 connects to the distribution channel 130. By providing a transition channel 140 that gradually widens in the fluid flow direction between the jet channel 120 and the distribution channel 130, the flow rate of the refrigerant fluid can be slowed down. At the same time, the refrigerant fluid expands along the transition channel 140 to the distribution channel 130 for distribution, which facilitates uniform distribution.

[0029] It is understandable that the refrigerant fluid will change its flow velocity after flowing out of the jet channel 120. If the refrigerant fluid is immediately diverted at this time, it is easy to cause the refrigerant fluid to become unstable. In order to keep the refrigerant fluid in a stable flow state, after the refrigerant fluid flows out of the jet channel 120, it first passes through the transition channel 140 to transition. After the refrigerant fluid flows in a stable state in the transition channel 140, it then enters the diversion channel 130 for diversion. That is, the transition channel 140 realizes the guidance of the refrigerant fluid and can keep the refrigerant fluid in a stable flow state.

[0030] In some embodiments of this application, such as Figure 1 As shown, the diversion channel 130 includes an expansion section 131 and a straight section 132. The expansion section 131 gradually widens in the fluid flow direction, while the orifice diameter of the straight section 132 remains consistent in the fluid flow direction. The narrow end of the expansion section 131 connects to the jet channel 120, and the wide end of the expansion section 131 connects to the straight section 132. By setting the expansion section 131, which gradually widens in the fluid flow direction, the flow rate of the refrigerant fluid can be slowed down. At the same time, the refrigerant fluid expands along the expansion section 131, facilitating uniform diversion. By setting the straight section 132, whose orifice diameter remains consistent in the fluid flow direction, the mixing of the refrigerant fluid can be intensified, improving the diversion effect.

[0031] like Figures 1-3 As shown, the distributor 100 also includes a plurality of outflow channels 160, each of which is connected to the end of the distributor channel 130 away from the jet channel 120. Optionally, the plurality of outflow channels 160 are evenly arranged along the circumference of the distributor 100. For example, as... Figure 2 As shown, the distributor 100 includes three outflow channels 160, which are evenly arranged along the circumference of the distributor 100, and each of the three outflow channels 160 is connected to the end of the distributor channel 130 away from the jet channel 120.

[0032] Optionally, a diversion cone 170 is provided within the diversion channel 130, with the smaller diameter end of the diversion cone 170 facing the jet channel 120. Specifically, a certain distance is maintained between the diversion cone 170 and the inner wall of the diversion channel 130, thereby forming a diversion gap between the diversion cone 170 and the inner wall of the diversion channel 130. This diversion gap is connected to multiple outlet channels 160. After the refrigerant fluid enters the diversion channel 130, it is diverted by the diversion cone 170 and enters the diversion gap between the diversion cone 170 and the inner wall of the diversion channel 130, and then enters each outlet channel 160 through the diversion gap. By providing the diversion cone 170 in the diversion channel 130, the refrigerant fluid is guided, and the refrigerant fluid is evenly introduced into each outlet channel 160.

[0033] Optionally, the cone angle of the diversion cone 170 is 65° to 75°. For example, the cone angle of the diversion cone 170 can be 65°, 66°, 67°, 68°, 69°, 70°, 71°, 72°, 73°, 74°, 75° or any range between two values, which can be set according to actual needs.

[0034] Optionally, to ensure uniform flow distribution, the flow-dividing cone 170 has a symmetrical structure, with its central axis coinciding with the central axis of the flow-dividing channel 130. The axially flowing refrigerant fluid is uniformly mixed and distributed, and then evenly distributed to each outflow pipe through the symmetrical structure, thus being sent to each heat exchange branch.

[0035] Optionally, the central axes of the inlet channel 110, the jet channel 120, and the branch channel 130 are aligned, which facilitates the adjustment and movement of the refrigerant fluid inside and avoids the phenomenon of turning during the flow from upstream to downstream, because turning will cause a large change in the flow velocity of the refrigerant fluid at various points, and the fluid direction will be difficult to control.

[0036] In some embodiments of this application, the inlet channel 110, the jet channel 120, and the diversion channel 130 are integrally formed structures to reduce processing difficulty and improve production efficiency.

[0037] Optionally, the distributor 100 may be made of copper. Optionally, the distributor 100 may be a one-piece molded structure to reduce processing difficulty and improve production efficiency.

[0038] For example, the shunt 100 can be a one-piece molded copper shunt. Using a one-piece copper shunt can effectively avoid the welding quality risks of brass shunts. The one-piece molding process has high production efficiency and directly reduces welding costs. In addition, the weight of a single copper shunt is lighter than that of a brass shunt.

[0039] This application also provides an air conditioner, which includes a splitter 100. The specific structure of the splitter 100 is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0040] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
