Description

Technical Field

[0001] The utility model relates to the technical field of HVAC equipment, in particular to a distributor, a diversion component and HVAC equipment. Background Art

[0002] In HVAC systems and related fluid distribution equipment, the role of diverters is crucial and directly affects the uniform distribution of fluids. However, diverters in the prior art mostly adopt a conventional conical structure design. Although it can achieve basic diversion functions, its flow uniformity is difficult to be effectively guaranteed. Especially during the processing, in order to achieve the ideal diversion effect, very high processing precision is required, and even secondary processing is required to achieve the flatness of the diverter cone surface. Due to the difficulty of processing and poor consistency, the existing diverter cone structure often leads to uneven fluid distribution, affecting the overall performance of the equipment. This problem not only affects the operating efficiency of the HVAC system, but may also cause the fluid pressure in certain areas of the HVAC system to be too high or too low, further affecting the stability of the HVAC system. Utility Model Content

[0003] The purpose of the present invention is to at least solve the problem of uneven flow distribution of the diverter, which is achieved through the following technical solutions:

[0004] The first aspect of the present invention provides a dispenser, comprising:

[0005] a shell, wherein the shell is provided with an inlet hole and an expansion cavity;

[0006] a plate body, the plate body being disposed on the shell and enclosing the expansion cavity, the plate body being provided with at least three diversion holes at intervals;

[0007] A diverter cone is arranged inside the expansion cavity and connected to the plate body. The top end of the diverter cone is arranged opposite to the inflow hole. The diverter cone is provided with at least three guide surfaces interconnected along its circumference. At least three guide surfaces are arranged in a one-to-one correspondence with at least three diverter holes. The guide surfaces are used to guide the fluid from the inflow hole to the diverter hole.

[0008] According to the distributor of the present invention, an inflow hole on the housing guides the fluid into the expansion chamber, allowing the fluid to fully expand and decelerate in the expansion chamber. A diverter cone is positioned within the expansion chamber, and the inflow hole is positioned relative to the top of the diverter cone, effectively directing the fluid directly to the center of the diverter cone. This arrangement ensures that upon entering the expansion chamber, the fluid first contacts the top of the diverter cone, allowing the fluid to be evenly distributed across the different guide surfaces of the diverter cone. This not only reduces fluid turbulence within the expansion chamber but also ensures consistency in the flow rate and flow rate of the fluid entering each guide surface. The at least three guide surfaces on the diverter cone are interconnected along its circumference and are arranged one-to-one with the diverter holes. This design ensures that each guide surface specifically guides the fluid into its corresponding diverter hole. Because the guide surfaces are continuously connected, they effectively guide the fluid downward from the top of the diverter cone, avoiding collisions and turbulence within the cavity and ensuring uniform distribution of the fluid. After entering through the inflow hole, the fluid directly contacts the top of the diverter cone and is then smoothly distributed along the guide surfaces to each diverter hole. Due to the corresponding relationship between the guide surface and the diversion hole, the fluid flow received by each diversion hole is relatively consistent, further improving the diversion uniformity of the system.

[0009] In addition, the dispenser according to the present invention may also have the following additional technical features:

[0010] In some embodiments of the present invention, along the direction from the top end of the diverter cone to the bottom end of the diverter cone, the guide surface includes a first guide section and a second guide section connected in sequence, and the taper of the first guide section is smaller than the taper of the second guide section.

[0011] In some embodiments of the present invention, the guide surface further includes a transition section, which is provided at the connection between the second guide section and the plate body, and the transition section has a rounded corner.

[0012] In some embodiments of the present invention, the second guide section is a concave surface.

[0013] In some embodiments of the present invention, the diverter cone further includes a guide rib, which is arranged between two adjacent guide surfaces, one end of the guide rib is connected to the top of the diverter cone, and the other end of the guide rib is connected to the bottom of the diverter cone.

[0014] In some embodiments of the present invention, at least three diverter holes are arranged at equal intervals along the circumferential direction of the diverter cone.

[0015] In some embodiments of the present invention, between a corresponding set of the guide surfaces and the diverter holes, the midpoint of the bottom edge of the guide surface and the top of the diverter cone form a straight line, and the straight line and the axis of the diverter cone form a plane, and the axis of the diverter hole is on the plane.

[0016] In some embodiments of the present invention, the diverter cone is coaxially arranged with the inflow hole.

[0017] In some embodiments of the present invention, the plate body includes a first plate body, at least three diverter holes are opened on the first plate body, and the diverter cone and the first plate body are an integrated structure.

[0018] In some embodiments of the present invention, the plate body further includes a second plate body connected to the first plate body, the second plate body is provided with at least three insertion holes, and the diversion holes are connected to the insertion holes in a one-to-one correspondence.

[0019] A second aspect of the present invention provides a flow diversion assembly, comprising:

[0020] the aforementioned dispenser;

[0021] a main flow pipe, the main flow pipe being connected to the inflow hole;

[0022] A shunt pipe, wherein the shunt pipe is connected to the shunt hole.

[0023] In some embodiments of the present invention, the diverter tube is inserted into the insertion hole of the second plate body of the plate body and communicates with the diverter hole.

[0024] A third aspect of the present invention provides a HVAC device, which includes the above-mentioned diversion component. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] like Figures 1 to 10 As shown, according to an embodiment of the present invention, a distributor 100 is proposed, comprising a shell 10, a plate body 20 and a diverter cone 30, wherein the shell 10 is provided with an inflow hole 111, the plate body 20 closes the shell 10 to form an expansion cavity 103, and at least three diverter holes 201 are spaced apart on the plate body 20, the diverter cone 30 is arranged inside the expansion cavity 103 and connected to the plate body 20, the top of the diverter cone 30 is arranged opposite to the inflow hole 111, and the diverter cone 30 is provided with at least three guide surfaces 311 interconnected along its circumference, and the at least three guide surfaces 311 are arranged one-to-one with the at least three diverter holes 201, and the guide surface 311 is used to guide the fluid from the inflow hole 111 to the diverter hole 201.

[0054] According to the distributor 100 of the present invention, the inflow hole 111 on the shell 10 guides the fluid into the expansion chamber 103, where the fluid can be fully expanded and decelerated. The diverter cone 30 is arranged in the expansion chamber 103. The position of the inflow hole 111 is relative to the top of the diverter cone 30, which can effectively guide the fluid to directly act on the central area of ​​the diverter cone 30. This arrangement ensures that the fluid first contacts the top of the diverter cone 30 after entering the expansion chamber 103, so that the fluid can be evenly dispersed to the different guide surfaces 311 on the surface of the diverter cone 30. This not only reduces the turbulence of the fluid in the expansion chamber 103, but also ensures the consistency of the flow rate and flow rate of the fluid entering each guide surface 311. At least three guide surfaces 311 on the diverter cone 30 are interconnected along its circumference and are arranged one-to-one with the diverter holes 201. This design ensures that each guide surface 311 specifically guides the fluid into the corresponding diverter hole 201. Because the guide surfaces 311 are continuously connected, they effectively guide the fluid downward from the top of the diverter cone 30, preventing collisions and turbulence within the cavity and ensuring uniform fluid distribution. After entering through the inlet 111, the fluid directly contacts the top of the diverter cone 30 before being smoothly dispersed along the guide surfaces 311 to each diverter hole 201. Due to the corresponding relationship between the guide surfaces 311 and the diverter holes 201, each diverter hole 201 receives a relatively consistent fluid flow rate, further improving the uniformity of the system's flow distribution.

[0055] In some embodiments, along the direction from the top of the diverter cone 30 to the bottom of the diverter cone 30, the guide surface 311 includes a first guide section 3111 and a second guide section 3112 connected in sequence, the first guide section 3111 has a first angle between its slant height and the axis of the diverter cone 30, and the second guide section 3112 has a second angle between its slant height and the axis of the diverter cone 30, and the first angle is greater than the second angle. The first guide section 3111 is located near the top of the diverter cone 30 and has a steeper inclination, with a larger first angle between its slant height and the axis of the diverter cone 30. The second guide section 3112 is located in an area near the bottom of the diverter cone 30 and has a gentler inclination, with a smaller second angle between its slant height and the axis of the diverter cone 30. The first guide section 3111 is designed to handle high-speed fluids and larger droplets entering the expansion chamber 103. When the fluid passes through the first guide section 3111, larger droplets collide with the first guide section 3111, causing the droplets to break and disperse into smaller droplets. This effectively improves the uniformity of liquid dispersion and reduces turbulence and fluctuations in the expansion chamber 103. The second guide section 3112 further guides the dispersed droplets at a smaller angle, allowing them to enter the diversion holes 201 at a more stable speed and direction, ensuring uniformity of the fluid entering each diversion hole 201.

[0056] Specifically, along the direction from the top to the bottom of the diverter cone 30, the projected length of the oblique height of the first guide section 3111 on the axis of the diverter cone 30 is a first length, and the projected length of the oblique height of the second guide section 3112 on the axis of the diverter cone 30 is a second length. The ratio of the first length to the second length is between 1:5 and 1:7. The shorter projected length and larger angle of the first guide section 3111 facilitate rapid liquid dispersion. By limiting the length of the first guide section 3111, the collision and dispersion of droplets can be completed in a short period of time, allowing the fluid to achieve good dispersion in the initial stage. The longer second guide section 3112 further stabilizes the fluid after collision. The longer projected length of the second guide section 3112 ensures that the liquid has sufficient time and distance to flow stably after dispersion, reducing turbulence and flow fluctuations, thereby improving the uniformity of fluid distribution. By controlling the ratio of the first length to the second length between 1:5 and 1:7, a balance is ensured between liquid dispersion efficiency and flow stability. The shorter first section focuses on the dispersion of liquid droplets, while the longer second section ensures the smooth flow of the fluid, allowing the liquid to be further evenly introduced into each diversion hole 201.

[0057] Specifically, the first angle can range from 30° to 45°, and the second angle can range from 10° to 25°. A larger first angle of the first guide section 3111, set between 30° and 45°, ensures that the incoming fluid (especially droplets) undergoes a violent collision and dispersion upon contact with the guide surface 311. This is because a larger angle increases the contact angle between the liquid and the guide surface 311, generating a stronger impact force, thereby causing larger droplets to quickly break into smaller droplets and promoting uniform distribution of the liquid in the initial stage. When a fluid enters, it typically has a high velocity and kinetic energy. A larger first angle (between 30° and 45°) can effectively convert the high kinetic energy of the fluid into a dispersing force, causing the liquid to quickly collide with the guide surface 311. This maximizes the utilization of the fluid's kinetic energy while it is still in a high kinetic energy state, quickly completing the initial dispersion process. If the first angle is too small, the fluid will not be effectively dispersed, but will flow slowly along the guide surface 311, which will cause the fluid to remain in the cavity for an excessively long time, increasing the risk of turbulence formation. The angle of 30° to 45° can quickly disperse the fluid, reduce the turbulence inside the expansion cavity 103, and ensure the uniform flow of the fluid. The function of the second guide section 3112 is to smoothly guide the dispersed droplets to the diverter hole 201. If the second angle is large, the flow speed of the fluid may be too fast, resulting in unnecessary collisions or turbulence when entering the diverter hole 201. Therefore, a smaller angle of 10° to 25° can slow down the speed of the fluid, provide sufficient guiding paths, and enable the fluid to enter the diverter hole 201 in a more stable state, thereby reducing secondary dispersion or turbulence. A smaller angle (10° to 25°) can reduce the impact force between the fluid and the guide surface 311, avoiding secondary collisions or rebounds of the fluid during the diversion process. If the angle is too large, the fluid enters the diverter hole 201 at a faster speed, which easily leads to uneven distribution of the fluid to each diverter hole 201, while a smaller angle can gradually slow down the liquid, ensuring that the fluid flows stably and is evenly distributed. After the fluid passes through the first guide section 3111, its flow rate has decreased somewhat. At this point, the second guide section 3112 is required to further smoothly guide the fluid. A range of 10° to 25° ensures smooth liquid flow while also providing a sufficient path length to maintain a good flow state upon entering the diversion hole 201, ensuring uniformity.

[0058] It is understandable that if Figure 5 and Figure 6As shown, the guide surface 311 also includes a transition section 3113, which is arranged at the connection between the second guide section 3112 and the plate body 20, and the transition section 3113 is a rounded chamfer. In this embodiment, along the direction from the top of the diverter cone 30 to the ground, the guide surface 311 is composed of a first guide section 3111, a second guide section 3112 and a transition section 3113 in sequence, and the transition section 3113 is arranged at the connection between the second guide section 3112 and the plate body 20. It is a rounded chamfer structure that can smoothly guide the fluid through the bottom of the diverter cone 30 and enter the diverter hole 201. The rounded chamfer design of the transition section 3113 ensures a smooth transition of the fluid during the diversion process and avoids the rebound phenomenon caused by the fluid colliding with the bottom end of the diverter cone 30 at high speed. Droplet rebound can cause local fluid aggregation or excessive flow, thereby affecting the uniform distribution of the diverter hole 201. The rounded chamfer can effectively disperse the impact force of the liquid, ensure that the liquid flows evenly into the diversion hole 201, and reduce the uneven diversion caused by rebound. The smooth transition function of the transition section 3113 can effectively reduce the turbulence of the fluid. When the fluid passes through the second guide section 3112, its speed will decrease. The transition section 3113 can further slow down the speed change of the fluid, avoiding the generation of irregular eddies or turbulence when the fluid approaches the diversion hole 201. This design helps to maintain the smooth flow of the fluid and reduce energy loss, thereby improving the diversion efficiency. At the same time, the rounded chamfer design of the transition section 3113 not only improves the smooth transition of the fluid, but also enhances the overall flow stability of the system. After passing through the transition section 3113, the liquid can enter the diversion hole 201 more naturally, avoiding flow blockage or impact caused by abrupt angle changes. This smooth flow path ensures that the fluid flow received by each diversion hole 201 is consistent, ultimately improving the working performance of the distributor 100.

[0059] It is understandable that if Figure 7 and Figure 8As shown, the second guide section 3112 is a concave surface. The concave surface design of the second guide section 3112 can better capture the fluid flow through its curved geometric shape. After the fluid is initially dispersed through the first guide section 3111, it will be gradually guided to the diversion hole 201 when entering the concave surface. The curvature of the concave surface can make the fluid flow more smoothly on the surface, reduce the fluid rebound or turbulence caused by surface mutations, and significantly improve the fluid diversion uniformity. Compared with the straight guide surface 311, the concave surface can provide a smoother path for the fluid, guiding the fluid to gradually slow down and flow smoothly to the diversion hole 201. When the fluid flows along the concave surface, the speed change is relatively gentle, and there will be no sudden acceleration or deceleration, thereby reducing turbulence and energy loss. This effect is particularly suitable for application scenarios that require high-precision diversion. At the same time, the design of the concave surface optimizes the flow path of the fluid and provides more precise fluid control than the straight guide section. The concave surface can guide the liquid through its curved structure, ensuring that the fluid gradually enters the diversion hole 201, avoiding uneven distribution during the diversion process, and improving the diversion efficiency of the distributor 100.

[0060] In some embodiments, the diverter cone 30 further includes a guide rib 312, which is positioned along the intersecting edge of two adjacent diverter surfaces 311. One end of the guide rib 312 connects to the top of the diverter cone 30, and the other end connects to the bottom of the diverter cone 30. By positioning the guide rib 312 at the intersection of adjacent diverter surfaces 311, the fluid can be more orderly distributed to the various diverter holes 201 under the guidance of the diverter surfaces 311. The provision of the guide rib 312 further standardizes the fluid flow path. As the fluid flows through the diverter surfaces 311, it flows along the boundaries of the guide rib 312, preventing irregular or lateral flow between the diverter surfaces 311. This precise guidance allows the fluid to enter the corresponding diverter hole 201 in a more orderly manner, improving the accuracy and uniformity of the diversion. Furthermore, in addition to guiding the fluid, the guide rib 312 also strengthens the structure of the diverter cone 30 itself. The guide ribs 312 are arranged along the intersecting edges of adjacent guide surfaces 311, which not only makes the overall structure of the diverter cone 30 more stable, but also can effectively withstand the force of fluid impact, thereby extending the service life of the diverter cone 30, especially in an environment with high fluid pressure.

[0061] In some embodiments, at least three diverter holes 201 are spaced at equal intervals along the circumference of the diverter cone 30. By arranging the diverter holes 201 at equal intervals, the fluid can be evenly distributed along the circumference of the diverter cone 30. Because the spacing between each diverter hole 201 is equal, there is no deviation or imbalance when the fluid enters the diverter hole 201 from each guide surface 311, ensuring uniform fluid distribution. This helps avoid localized flow rates that are excessive or insufficient. Furthermore, the equally spaced diverter holes 201 promote balanced fluid distribution within the expansion chamber 103. When the fluid passes through the guide surface 311, each diverter hole 201 receives the same amount of fluid, further improving the balance of the system. This design not only improves fluid distribution accuracy but also reduces the occurrence of uneven flow within the expansion chamber 103. If the spacing between the diverter holes 201 is uneven, excessive flow from some diverter holes 201 may occur, increasing local pressure and affecting the stability of the distributor 100. The equal spacing setting can effectively avoid this problem and ensure that the fluid flow rate and pressure received by each diversion hole 201 are similar, thereby reducing local pressure fluctuations and improving the overall stability of the system.

[0062] like Figure 4 As shown, in some embodiments, between a corresponding set of guide surfaces 311 and the diversion hole 201, the bottom edge of the guide surface 311 has a midpoint (such as Figure 4 As shown in M ​​in FIG), the midpoint of the bottom edge of the guide surface 311 and the top of the diverter cone 30 form a straight line, and the straight line and the axis of the diverter cone 30 form a plane (as shown in FIG. Figure 4 and Figure 5 (as shown in the N plane in the figure), the axis of the diverter hole 201 lies on this plane. This means that during the flow of the fluid on the guide surface 311, its flow path extends to the axis of the diverter hole 201. This design ensures that the fluid can smoothly enter the diverter hole 201 along the centerline of the guide surface 311 during the diversion process, avoiding sudden turns or turbulence in the fluid path, thereby improving the uniformity of the diversion.

[0063] It is understandable that when the second guide section 3112 is a concave surface, the concave point of the concave surface is located on the above-mentioned conical section, and the concave surface has an axis of symmetry, which is also located on the conical section. The axis of symmetry of the concave surface is located on the truncated cone surface, ensuring that the fluid is naturally guided along the symmetrical path of the concave surface during the flow process. Since the axis of symmetry is located on the truncated cone surface, the fluid can be evenly distributed on both sides of the concave surface, avoiding the asymmetry of the flow. This design helps to reduce the deviation of the fluid before entering the diversion hole 201, and ensures that the fluid is evenly distributed to each diversion hole 201. The axis of symmetry provides a stable geometric reference, and the fluid flows symmetrically on the concave surface, and the flow rate and pressure distribution are more uniform. The incidence of turbulence and disturbance is greatly reduced, especially when the fluid passes through the concave surface, because the motion trajectory of the fluid is stable due to its symmetry, reducing turbulence and energy loss. This stable flow path can improve the smoothness of the entire diversion process.

[0064] In some embodiments, the diverter cone 30 is coaxially arranged with the inlet hole 111. This coaxial arrangement ensures that after the fluid enters the expansion chamber 103 from the inlet hole 111, it flows directly along the central axis of the diverter cone 30, thereby improving the accuracy and stability of fluid guidance. After entering the diverter cone 30, the fluid is gradually dispersed along the guide surface 311 to each diverter hole 201, avoiding deviation and turbulence during fluid entry, thereby improving the stability and uniformity of fluid distribution.

[0065] In some embodiments, the diverter cone 30 is a regular pyramid structure, that is, the bottom end of the diverter cone 30 is a regular polygon, and the top end is located on the vertical center line of the bottom end of the regular polygon. This structure makes the various guide surfaces 311 of the diverter cone 30 symmetrically distributed, and the diversion path is more consistent and uniform. The symmetrical structure of the regular pyramid ensures the uniform distribution of the guide surfaces 311, so that after the fluid enters the diverter cone 30, it can flow along each guide surface 311 in the same manner and path. This uniform distribution method reduces the unevenness that occurs during the fluid diversion process, ensures that the amount of fluid received by each diversion hole 201 is more consistent, and improves the uniformity of the diversion. At the same time, the various guide surfaces 311 in the regular pyramid structure are evenly stressed, reducing the local impact on the structure during the fluid flow process. Through the evenly distributed guide surfaces 311, the regular pyramid can withstand the pressure of the fluid without structural imbalance, thereby enhancing the stability and durability of the system, especially in high-pressure fluid applications.

[0066] In some embodiments, the plate body 20 includes a first plate body 21 and a second plate body 22 connected to each other, at least three diverter holes 201 are provided on the first plate body 21, and at least three insertion holes 202 are provided on the second plate body 22, at least three diverter holes 201 are connected to at least three insertion holes 202 in a one-to-one correspondence, and the diverter cone 30 and the first plate body 21 are an integral structure. The diverter cone 30 and the first plate body 21 are both made of stainless steel, and the diverter cone 30 and the first plate body 21 are extruded from stainless steel, integrating the two parts in one production step, avoiding the complex process of separate processing and then assembly. This not only simplifies the production process and reduces possible errors in each link, but also significantly improves production efficiency. For the manufacturing process, integral extrusion molding helps to reduce manufacturing costs and shorten the production cycle. Through integral extrusion molding, the matching accuracy between the diverter cone 30 and the first plate body 21 is significantly improved, avoiding dimensional deviations caused by multi-step processing and assembly. The integrated manufacturing process ensures product consistency in geometry, size, and surface finish, thereby improving the processing quality of the entire system. This consistency ensures the precise matching of the diverter cone 30 and the diverter hole 201, so that the fluid flow received by each diverter hole 201 is balanced. At the same time, the integral molding of the diverter cone 30 and the diverter hole 201 plate eliminates the seams and irregular edges between the parts, thereby providing a smooth path for fluid flow. The smooth flow path reduces turbulence and turbulence, allowing the fluid to pass evenly through each diverter hole 201, improving the overall uniformity of the distributor 100. The fluid distribution is more uniform, which can effectively prevent local flow from being too large or too small.

[0067] In order to more clearly illustrate the technical solution, the present utility model provides three specific embodiments.

[0068] Example 1

[0069] like Figures 3 to 6 As shown, the distributor 100 of the first embodiment includes a shell 10, a plate body 20 and a diverter cone 30. An inflow hole 111 is provided at the bottom of the shell 10, and the plate body 20 closes the top of the shell 10 to form an expansion cavity 103. The opening of the shell 10 is circular, and the plate body 20 is composed of a circular first plate body 21 and a second plate body 22, wherein the first plate body 21 is located below the second plate body 22 (i.e., close to the inflow hole 111). The diverter cone 30 is located in the expansion cavity 103, has a regular octagonal pyramid structure, and is integrally formed with the first plate body 21. The intersection of the vertical line between the top and bottom ends of the diverter cone 30 coincides with the center of the circle of the first plate body 21.

[0070] Eight diverter holes 201 are evenly spaced on the first plate 21, and eight insertion holes 202 are also evenly spaced on the second plate 22. The diverter holes 201 correspond to the insertion holes 202 one by one and are coaxially connected. Each diverter hole 201 corresponds to a side surface (i.e., a guide surface 311) of a regular octagonal pyramid. Between each corresponding guide surface 311 and diverter hole 201, the inclined height of the guide surface 311 forms a truncated cone surface with the axis of the diverter cone 30, and the center of the diverter hole 201 is located on the extension surface of this truncated cone surface. In addition, the diverter cone 30 is coaxially arranged with the inflow hole 111.

[0071] Along the direction from the top to the bottom of the diverter cone 30, the guide surface 311 includes, in sequence, a first guide section 3111, a second guide section 3112, and a transition section 3113. The first guide section 3111 is near the top, and the transition section 3113 is near the bottom. The first guide section 3111 forms a first angle with the axis of the diverter cone 30, while the second guide section 3112 forms a second angle with the axis of the diverter cone 30, with the first angle being greater than the second angle. The transition section 3113 has a rounded chamfer design to smoothly connect the guide surface 311 with the diverter hole 201.

[0072] In the first embodiment, the first guide section 3111 and the second guide section 3112 are both linear guide sections.

[0073] Example 2

[0074] like Figure 7 and Figure 8 As shown, based on the first embodiment, the second guide section 3112 in the second embodiment is a curved surface.

[0075] Example 3

[0076] like Figure 9 and Figure 10 As shown, based on the second embodiment, a guide rib 312 is provided on the intersecting edges of adjacent guide surfaces 311 , one end of the guide rib 312 is connected to the top of the diverter cone 30 , and the other end of the guide rib 312 is connected to the bottom of the diverter cone 30 .

[0077] like Figures 11 to 13As shown, this embodiment also provides a flow diversion assembly 1000, which includes the above-mentioned distributor 100, a main flow pipe 300, and a diversion pipe 200. The main flow pipe includes an inlet pipe 301 and an inlet flow pipe 302 connected to each other. The main flow pipe 300 is connected to the inlet hole 111 through the inlet pipe 301. Specifically, the housing 10 is provided with a first inserting portion 11, which is used to accommodate the inlet pipe 301. The diversion pipe 200 is connected to the diversion hole 201 and is inserted into the inserting hole 202 of the second plate body 22. The flow diversion assembly 1000 is based on the distributor 100 as the core part, and achieves uniform distribution of the fluid through its diversion cone 30, the first plate body 21, and the diversion hole 201. The main pipe 300 is connected to the inflow hole 111 of the distributor 100 and is responsible for introducing the fluid from the main system into the expansion chamber 103, while the branch pipe 200 is connected to the branch hole 201 and is used to further transport the fluid from the branch hole 201 to various downstream pipelines or terminal devices.

[0078] like Figure 14 As shown, this embodiment also provides a HVAC device 1, which includes the above-mentioned diversion component 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 first heat exchanger 2000 receives the refrigerant from the diversion component 1000, the first heat exchanger 2000 performs a heat absorption process, causing the refrigerant to evaporate and absorb heat from the environment. The low-pressure gaseous refrigerant received by the compressor 4000 from the first heat exchanger 2000 is pressurized by the compressor 4000 and converted into high-pressure gaseous refrigerant, which is then transported to the four-way valve 6000 through a pipeline. The four-way valve is used to adjust the flow direction of the refrigerant and switch between cooling and heating modes. In cooling mode, the refrigerant passes through the second heat exchanger 3000, the cooling throttle valve 5000, the flow diverter assembly 1000, and the first heat exchanger 2000 before returning to the compressor. In heating mode, the refrigerant returns from the first heat exchanger 2000 to the compressor 4000. The design of the entire HVAC system 1 achieves higher fluid control precision through the flow diverter assembly 1000, enhancing system stability. The precise coordination and flow control of each component ensures stable operation under different operating conditions, reducing failures and maintenance requirements.
