Description
Technical Field
[0001] This utility model relates to the field of refrigerant distribution technology, and more specifically, to a distributor with a novel structure. Background Technology
[0002] In air conditioners, the distributor, used for refrigerant distribution, is a key refrigeration component. Its main function is to thoroughly mix the gas-liquid two-phase refrigerant and then evenly distribute it to the various channels of the heat exchanger. The structure of the distributor determines its performance, namely its refrigerant distribution capacity, which in turn directly affects the overall energy efficiency of the unit.
[0003] like Figure 7 and Figure 8 As shown, existing dispensers are mainly divided into two types: 1. Umbrella-shaped brass dispenser ( Figure 7 Its structure is made of brass integral casting and then machined. However, the distributor adopts an integral structure, which limits the processing method. Its internal shape is monolithic and cannot be adjusted according to actual needs. The refrigerant distribution efficiency is relatively low. During the whole machine development process, engineers need to repeatedly adjust the length of the capillary tube based on test data. The integral casting process has high requirements. If the casting temperature, pouring time and cooling method are not well controlled, defects such as sand holes, cracks and air holes are easy to occur, resulting in refrigerant leakage; 2. Barrel-type copper distributor ( Figure 8 This distributor relies solely on the end blockage for refrigerant mixing, resulting in suboptimal mixing and noise generation.
[0004] In summary, while existing distributors can achieve the diversion effect in practical applications, their simple internal shape and complex casting process prevent them from being flexibly adjusted according to actual needs, resulting in unsatisfactory mixing effects and a tendency to generate noise.
[0005] Therefore, a new type of distributor with a completely new structure is urgently needed to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a dispenser with a novel structure to solve the problems mentioned in the background art.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] A novel dispenser includes a housing, which is hollow. The housing is integrally formed from an outlet section and an inlet section located at the bottom of the outlet section and gradually tapering inward along its axial direction. The dispenser also includes:
[0009] An end cap is coaxially fixed to the outlet section of the housing, and multiple sets of connection holes are arrayed on the end face of the end cap along its axial direction.
[0010] The distributor is fixedly connected to the inner wall of the end cap and is used for mixing and guiding the gas-liquid refrigerant.
[0011] The first connecting pipe is connected to the inlet section of the housing, and the inlet section of the housing is also provided with a connecting structure for increasing the flow rate of the vapor-liquid refrigerant.
[0012] As a preferred technical solution of this application, the diverter includes a first conical surface connected to the inner top wall of the end cap and gradually tapering downwards and inwards into a frustum shape, and a second conical surface connected to the bottom end of the first conical surface and extending inwards into a cone shape.
[0013] As a preferred technical solution of this application, the end cap and the shell are sealed by welding.
[0014] As a preferred technical solution of this application, the connection structure is specifically a gasket, which is disposed at the junction of the first connecting pipe and the inlet section of the shell.
[0015] As a preferred technical solution of this application, the connection structure is specifically a flanged hole disposed in the inlet section of the housing with its opening direction corresponding to the second conical surface.
[0016] As a preferred technical solution of this application, a diversion pipe is detachably connected to the inner wall of the connection hole.
[0017] As a preferred technical solution of this application, a filter screen is also provided on the inner wall of the first connecting pipe.
[0018] As a preferred technical solution of this application, a second connecting pipe is fixedly connected to the end of the first connecting pipe away from the shell, and a pipe joint is provided at the output end of the second connecting pipe.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] In the scheme of this application:
[0021] 1. Through modular design, the whole can be processed by stamping, which simplifies the processing method, reduces production costs, improves processing flexibility, and effectively improves production efficiency and reliability;
[0022] 2. With the independent configuration of the flow divider, the flow divider is no longer limited by traditional processing methods. Its shape and size can be flexibly adjusted and optimized according to the actual fluid distribution needs. Whether it is a complex pipeline layout or a specific flow distribution requirement, it can be met through customized flow divider design, which greatly improves the adaptability and flexibility of the system.
[0023] 3. By cleverly integrating the filter's function through the set filter screen, the number of components is reduced. More importantly, it avoids the need to add additional filters during system design and installation. This not only saves on the cost of purchasing and installing filters, but also reduces potential leak points and failure points, thereby lowering the overall cost of the air conditioner.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Example
[0035] like Figure 1-2As shown, this embodiment proposes a novel distributor with a housing 1, which is a hollow structure.

[0037] The distributor 3 is fixedly connected to the inner wall of the end cap 2 and is used for mixing and guiding the gas-liquid refrigerant.
[0038] The first connecting pipe 4 is connected to the inlet section of the housing 1, and the inlet section of the housing 1 is also provided with a connecting structure for increasing the flow rate of the vapor-liquid refrigerant.
[0039] With the independent configuration of the flow divider 3, the flow divider 3 is no longer limited by traditional processing methods. Its shape and size can be flexibly adjusted and optimized according to actual fluid distribution needs. Whether it is a complex pipeline layout or a specific flow distribution requirement, it can be met through the customized flow divider 3 design, which greatly improves the adaptability and flexibility of the system.
[0040] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the distributor 3 further includes a first conical surface 31 connected to the inner top wall of the end cover 2 and gradually tapering downwards and inwards into a frustum shape, and a second conical surface 32 connected to the bottom end of the first conical surface 31 and extending inwards into a cone shape. The first conical surface 31 on the distributor 3 serves to guide the flow, and the second conical surface 32 serves to mix the vapor and liquid refrigerant. The distributor 3 is set separately, and the shape and size of the distributor 3 can be flexibly adjusted as needed, without being constrained by the processing method.
[0041] like Figure 2 and Figure 4 As shown, in a preferred embodiment, based on the above method, the connection structure is further specifically a gasket 5. The gasket 5 is disposed at the junction of the first connecting pipe 4 and the inlet section of the housing 1. After the vapor-liquid refrigerant enters through the first connecting pipe 4 and passes through the gasket 5, it is accelerated and blown onto the distributor 3 for mixing and then guided by the distributor 3 to the connecting hole 6 for discharge. Example
[0042] like Figure 1-2 As shown, this embodiment proposes a novel distributor with a housing 1, which is a hollow structure. The housing 1 is integrally formed from an outlet section and an inlet section located at the bottom of the outlet section and gradually tapering inward along its axial direction. It also includes:
[0043] End cap 2 is coaxially fixedly connected to the outlet section of housing 1, and multiple sets of connection holes 6 are arrayed along its axial direction on the end face of end cap 2.
[0044] The distributor 3 is fixedly connected to the inner wall of the end cap 2 and is used for mixing and guiding the gas-liquid refrigerant.
[0045] The first connecting pipe 4 is connected to the inlet section of the housing 1, and the inlet section of the housing 1 is also provided with a connecting structure for increasing the flow rate of the vapor-liquid refrigerant.
[0046] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the end cap 2 and the housing 1 are further sealed by welding. The end cap 2 is sleeved on the outer wall of the expansion section of the housing 1 and fixedly sealed to the housing 1 by welding, or the end cap 2 is sleeved on the inner wall of the expansion section of the housing 1 and fixedly sealed to the housing 1 by welding. The choice can be flexible. Example
[0047] like Figure 1-2 As shown, this embodiment proposes a novel distributor with a housing 1, which is a hollow structure. The housing 1 is integrally formed from an outlet section and an inlet section located at the bottom of the outlet section and gradually tapering inward along its axial direction. It also includes:
[0048] End cap 2 is coaxially fixedly connected to the outlet section of housing 1, and multiple sets of connection holes 6 are arrayed along its axial direction on the end face of end cap 2.
[0049] The distributor 3 is fixedly connected to the inner wall of the end cap 2 and is used for mixing and guiding the gas-liquid refrigerant.
[0050] The first connecting pipe 4 is connected to the inlet section of the housing 1, and the inlet section of the housing 1 is also provided with a connecting structure for increasing the flow rate of the vapor-liquid refrigerant.
[0051] like Figure 5 As shown, in a preferred embodiment, based on the above method, the diverter 3 further includes a first conical surface 31 connected to the inner top wall of the end cap 2 and gradually tapering downward and inward into a frustum shape, and a second conical surface 32 connected to the bottom end of the first conical surface 31 and extending inward therein into a conical shape.
[0052] like Figure 2 As shown, in a preferred embodiment, based on the above method, the connection structure is further provided as a flanged hole 11 set in the inlet section of the housing 1 with the opening direction corresponding to the second conical surface 32. After the gas-liquid refrigerant enters through the first connecting pipe 4, it passes through the flanged hole 11, accelerates the mixing on the distributor 3, and is guided by the distributor 3 to the connecting hole 6 for discharge. Example
[0053] like Figure 1 As shown, in a preferred embodiment, based on Example 1, a diversion pipe 61 is detachably connected to the inner wall of the connection hole 6.
[0054] like Figure 1-6 As shown, in a preferred embodiment, based on the above method, a filter screen 7 is further provided on the inner wall of the first connecting pipe 4. The function of the filter screen 7 is to prevent impurities in the system from clogging the diversion pipe 61. The first connecting pipe 4 can be inserted into the housing 1, or the housing 1 can be inserted into the first connecting pipe 4. The material of the first connecting pipe 4 can be stainless steel or copper pipe. By setting the filter screen 7, the function of the filter is cleverly integrated, reducing the number of components. More importantly, it avoids the need to add an extra filter during the system design and installation process. In this way, not only is the cost of purchasing and installing filters saved, but also potential leakage points and failure points are reduced, thereby reducing the overall cost of the air conditioner.
[0055] The end of the first connecting pipe 4 away from the housing 1 is also fixedly connected to a second connecting pipe 8. The output end of the second connecting pipe 8 is provided with a pipe connector 81. The second connecting pipe 8 is a stainless steel pipe, and the pipe connector 81 can be made of stainless steel, brass, or copper.
[0056] Specifically, when using this new type of distributor: after connecting the first connecting pipe 4 and the branch pipe 61 to the external pipes respectively, after the gas-liquid refrigerant is introduced, it passes through the filter screen 7 and then through the gasket 5, and is accelerated towards the second conical surface 32 on the distributor 3 to mix the gas-liquid refrigerant. The mixed refrigerant is then guided through the distributor 3 to the connecting hole 6 for discharge. The function of the filter screen 7 is to prevent impurities in the system from clogging the branch pipe 61, thus avoiding the need to add a separate filter in the system design and reducing the cost of the air conditioner.

Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
