[0044] like Figures 1 to 6 As shown, Figure 2 The direction A in the middle represents the axial direction of the incoming flow pipe 302. The first aspect of the utility model proposes a diversion assembly 1000, including a distributor 100, an inlet pipe 301 and an incoming flow pipe 302. The distributor 100 has an inlet hole 111 and multiple diversion holes 201. The multiple diversion holes 201 are connected to the inlet hole 111. The inlet pipe 301 includes an inlet pipe 301. One end of the inlet pipe 301 is connected to the inlet hole 111. Along the axial direction of the incoming flow pipe 302, the first end of the incoming flow pipe 302 is in a closed state. The second end of the incoming flow pipe 302 is used for fluid inflow. The side wall of the incoming flow pipe 302 is provided with a first connecting hole 3021. The first connecting hole 3021 passes through the side wall of the incoming flow pipe 302 and is spaced from the first end. The first connecting hole 3021 is connected to the end of the inlet pipe 301 away from the distributor 100.

[0045] It is understood that the distributor 100 is a structure having an expansion cavity 103 formed therein. The distributor 100 also has an inflow hole 111 and a plurality of diversion holes 201. The inlet pipe 301 is connected to the expansion cavity 103 through the inflow hole 111. The diversion hole 201 is used to connect to the first connecting pipe 200. One end of the inlet pipe 301 is connected to the inflow hole 111. The two can be connected by snapping or welding. For example, the inlet pipe 301 is inserted into or sheathed at the opening of the inflow hole 111. The other end of the inlet pipe 301 is used to connect to the inflow pipe 302 to introduce the refrigerant. The inflow pipe 302 is set at an angle to the inlet pipe 301, and can be set vertically. The inflow pipe 302 is a blind pipe structure, that is, one end of the inflow pipe 302 is closed, and the other end of the inflow pipe 302 is used to introduce the refrigerant. A first connecting hole 3021 is provided on the side wall of the incoming flow tube 302. The first connecting hole 3021 penetrates the side wall of the incoming flow tube 302, allowing the end of the inlet tube 301 facing away from the distributor 100 to communicate with the incoming flow tube 302 through the first connecting hole 3021. Specifically, a flange or a connector can be provided at the first connecting hole 3021 to securely connect the end of the inlet tube 301 to the incoming flow tube 302, thereby improving connection reliability. A certain distance is provided between the first connecting hole 3021 and the first end of the incoming flow tube 302, so that after the refrigerant hits the end, a vortex is formed within the incoming flow tube 302, allowing the vapor and liquid phases of the refrigerant to be fully mixed at this point, thereby achieving uniform distribution of the vapor and liquid phases of the refrigerant.

[0046] The diversion component 1000 proposed in the first aspect of the present invention connects the end of the inlet pipe 301 with the side wall of the incoming flow pipe 302, and closes one end of the incoming flow pipe 302. The connection position between the inlet pipe 301 and the incoming flow pipe 302 is spaced from the end of the sealed edge of the incoming flow pipe 302, so that the refrigerant enters the incoming flow pipe 302 first. Due to the sealed edge of the end of the incoming flow pipe 302, the refrigerant will form a vortex in the incoming flow pipe 302 after hitting the end, so that the gas and liquid phases of the refrigerant are fully mixed here, thereby achieving uniform distribution of the gas and liquid phases of the refrigerant.

[0047] In some embodiments of the present invention, the axial direction of the incoming flow pipe 302 is perpendicular to the axial direction of the inlet pipe 301 .

[0048] It can be understood that the incoming flow tube 302 can be connected vertically to the inlet tube 301, for example, the incoming flow tube 302 is set horizontally, and the inlet tube 301 is set vertically and located above the inlet tube 301, so that after the refrigerant enters the incoming flow tube 302, it can collide with the closed end of the incoming flow tube 302 to form a return flow, so that the gas-liquid two-phase refrigerant in the incoming flow tube 302 is fully mixed, and then flows into the expansion cavity 103 through the inlet tube 301, so as to improve the mixing uniformity of the refrigerant before diversion, thereby improving the performance of the diversion component 1000.

[0049] In some embodiments of the present invention, along the axial direction of the inlet pipe 302, the distance between the first communication hole 3021 and the first end is a first distance ( Figure 2 d in the middle), the first distance is related to the inner diameter of the incoming flow pipe 302 ( Figure 2 The ratio of (shown in b) ranges from 1 to 3.

[0050] It can be understood that the ratio of the distance between the first connecting hole 3021 and the first end to the inner diameter of the incoming flow tube 302 is set in the range of 1 to 3, so that the distance between the first connecting hole 3021 and the first end is moderate, so as to generate a swirling flow through the end of the incoming flow tube 302 to fully mix the refrigerant, and the distance between the first connecting hole 3021 and the first end is not too far, thereby reducing the flow efficiency.

[0051] In some embodiments of the present invention, the inner diameter of the inlet pipe 302 (shown as d in the figure) is equal to the inner diameter of the inlet pipe 301 ( Figure 2 The ratio of (shown in c) ranges from 1.2 to 2.5.

[0052] It is understandable that the ratio of the inner diameter of the incoming flow pipe 302 to the inner diameter of the inlet pipe 301 is set in the range of 1.2 to 2.5, so that the difference in flow area between the incoming flow pipe 302 and the inlet pipe 301 is not too large or too small, thereby making the flow efficiency between the incoming flow pipe 302 and the inlet pipe 301 higher.

[0053] In some embodiments of the present invention, the diversion assembly 1000 also includes a connecting seat 303, which is installed on the side wall of the incoming flow pipe 302. The connecting seat 303 has a second connecting hole 3031, which passes through the connecting seat 303. The second connecting hole 3031 is connected to the first connecting hole 3021, and one axial end of the inlet pipe 301 is inserted into the second connecting hole 3031.

[0054] It is understandable that the connection seat 303 can be a rotating body structure, such as a cylindrical or truncated cone with a second connecting hole running through it. One axial end of the connection seat 303 can be adapted to the side wall shape of the incoming flow pipe 302, and is designed to have an arc-shaped end face, and is connected to the incoming flow pipe 302 by welding. A second connecting hole running through it is provided in the connection seat 303, one end of the second connecting hole is connected to the first connecting hole, and the other end is used to plug in the inlet pipe 301. The end of the inlet pipe 301 can be set in the second connecting hole by an interference fit, or the side wall of the inlet pipe 301 can be connected to the connection seat 303 by welding, so as to realize a fixed connection between the inlet pipe 301 and the connection group, thereby improving the connection reliability between the inlet pipe 301 and the incoming flow pipe 302.

[0055] In some embodiments of the present invention, the incoming flow pipe 302 has a flange structure arranged at the first connecting hole 3021, the flange structure extends along the circumference of the first connecting hole 3021, and is arranged on the outside of the incoming flow pipe 302, and part of the side wall of the inlet pipe 301 is connected to the flange structure.

[0056] It is understood that a portion of the wall of the incoming flow tube 302 can be bent to form a flange structure. The flange structure can be arranged in a circular pattern along the circumference of the first communicating hole 3021, or multiple flange structures can be intermittently provided along the circumference. Portions of the sidewall of the inlet tube 301 can be connected to the flange structure by welding, thereby expanding the connection area between the inlet tube 301 and the incoming flow tube 302 and thereby improving the reliability of the connection between the inlet tube 301 and the incoming flow tube 302.

[0057] In some embodiments of the present invention, the incoming flow pipe 302 includes a tube body 3022 and an end cover 3023. The end cover 3023 is arranged at one end of the tube body 3022 and seals the end of the tube body 3022. The other end of the tube body 3022 is used for fluid inflow, and a first connecting hole 3021 is provided on the side wall of the tube body 3022.

[0058] It can be understood that the tube body 3022 can be a straight tube with both ends open, and the end cover 3023 is sealed at one end of the tube body 3022. Specifically, the end cover 3023 can be sleeved on one end of the tube body 3022, or embedded in one end of the tube body 3022, and can also be set at one end of the tube body 3022 by means of a spinning seal, so that the incoming flow pipe 302 forms a blind pipe structure to generate a vortex flow in the incoming flow pipe 302, thereby improving the mixing uniformity of the gas-liquid two-phase refrigerant.

[0059] In some embodiments of the present invention, a distributor 100 includes a housing 10 and a plate 20. The housing 10 defines an expansion chamber 103 within the housing 10. The expansion chamber 103 is open. An inlet port 111 is provided on the housing 10 and communicates with the expansion chamber 103. An inlet pipe 301 is connected to the housing 10 at one end facing away from the inlet pipe 302. The plate 20 is provided at the open end, and a diversion port 201 is provided on the plate 20 and communicates with the expansion chamber 103.

[0060] It can be understood that the shell 10 can be a rotating body structure, such as a truncated cone or a hemispherical shape, with both ends of the shell 10 open, and a hemispherical expansion cavity 103 is defined inside. The plate 20 is adapted to the opening at one end of the shell 10 and is sealed on the opening. The plate 20 includes a first plate 21. The first plate 21 can be covered on the opening or embedded in the opening. A plurality of diverter holes 201 can be provided on the first plate 21 to connect the first connecting pipe 200. The diverter holes 201 can be circular or other regular polygons. The sizes of the diverter holes 201 can vary. The first plate 21 can have a certain thickness so that the first connecting pipe 200 is The tube 200 can be plugged into the diverter hole 201 to achieve connection, or the plate body 20 further includes a second plate body 21. A second plate body 22 is provided parallel to the first plate body 21 on the side facing away from the expansion chamber 103. The second plate body 22 is formed with multiple insertion holes 202 coaxially arranged with the diverter hole 201. The insertion holes 202 have a larger diameter than the diverter hole 201, so that the side wall of the first connecting tube 200 is connected to the hole wall of the insertion hole 202, and the end of the first connecting tube 200 abuts the bottom wall of the insertion hole 202, thereby securing the first connecting tube 200 at multiple angles and positions. The other end of the housing 10 is opened for connecting to the inlet tube 301. The inlet tube 301 can be plugged into the other end opening of the probe to achieve an interference fit, or it can be directly welded to the housing 10.

[0061] In some embodiments of the present invention, the diverter assembly 1000 also includes a diverter cone 30, the small diameter end of the diverter cone 30 is arranged in the expansion cavity 103, and the small diameter end of the diverter cone 30 is arranged toward the inflow hole 111, and multiple diverter holes 201 are arranged at intervals along the circumferential direction of the diverter cone 30.

[0062] It is understood that in order to improve the uniformity of the diversion, a diverter cone 30 can be set in the expansion chamber 103. The diverter cone 30 can be a cone or a pyramid. The large diameter end of the diverter cone 30 can be inserted into the mounting hole on the first plate 21, or the large diameter end of the diverter cone 30 can be welded or snap-connected to the side of the first plate 21 facing the expansion chamber 103. The diverter cone 30 can be a stamped structure. The large diameter end of the diverter cone 30 can have a flange, so that after the diverter cone 30 is inserted into the mounting hole, the flange can overlap the step structure of the first plate 21 away from the expansion chamber 103, and then the flange is connected to the first plate 21 by welding, so that the connection between the diverter cone 30 and the first plate 21 is more reliable. In addition, the outer periphery of the flange can also be connected to the wall of the mounting hole to improve the connection reliability. The profile of the diverter cone 30 can be arc-shaped, similar to the design of a submarine head, so that the flow resistance is smaller.

[0063] The second aspect of the present invention proposes a HVAC equipment 1, including the diversion assembly 1000 proposed in the first aspect of the present invention, the diversion assembly includes a distributor 100 and a second connecting pipe 300 arranged at the inlet end of the distributor 100, the second connecting pipe 200 includes an incoming flow pipe 302 and an inlet pipe 301 connected to the side wall of the incoming flow pipe 302.

[0064] It is understandable that if Figure 6 As shown, the HVAC equipment 1 provided in the second aspect of the present invention can be an air conditioner. The HVAC equipment 1 includes the aforementioned diversion assembly 1000, a first heat exchanger 2000, a second heat exchanger 3000, a compressor 4000, a refrigeration throttle valve 5000, and a four-way valve 6000. After the refrigerant is diverted from the diversion assembly 1000, it flows to the first heat exchanger 2000. The first heat exchanger 2000 absorbs heat from the refrigerant, which then absorbs heat from the environment and evaporates. The evaporated refrigerant flows to the compressor 4000 for pressurization, and the pressurized refrigerant is then delivered to the four-way valve 6000. The four-way valve 6000 is used to adjust the flow direction of the refrigerant to switch the air conditioner between cooling and heating modes. The diversion component 1000 can be used for diverting the refrigerant of the air conditioner outdoor unit before it enters the multiple heat exchange tubes of the first heat exchanger 2000. A structure for mixing the refrigerant is set at the inlet end of the diversion component 1000. The end of the inlet pipe 301 of the diversion component 1000 is connected to the side wall of the incoming flow pipe 302, and one end of the incoming flow pipe 302 is closed. The connection position between the inlet pipe 301 and the incoming flow pipe 302 is spaced from the end of the sealed edge of the incoming flow pipe 302, so that the refrigerant enters the incoming flow pipe 302 first. Due to the sealed end of the incoming flow pipe 302, the refrigerant will form a vortex in the incoming flow pipe 302 after hitting the end, so that the gas-liquid two-phase refrigerant is fully mixed here, thereby realizing uniform distribution of the gas-liquid two-phase refrigerant.

[0065] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
