Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, in particular to a distributor for a refrigeration system. Background Art

[0002] Distributors are widely used in air conditioner pipelines to divert refrigerant in the pipelines. They have an inlet and at least two outlets. The refrigerant flows into the refrigerant distributor from the inlet for full mixing and then flows out from at least two outlets, thereby achieving diversion of the refrigerant after uniform mixing. In the related art, when distributing multiple flow paths, it is usually necessary to use a distributor to distribute the flow paths. In order to avoid system blockage affecting the uniformity of distribution, a filter is usually welded at the upstream end of the distributor. However, adding a filter at the upstream end of the distributor will increase processing time and processing costs. In addition, the welding process is also prone to problems such as welding blockage, welding slag, and welding nodules.

[0003] The existing Chinese utility model patent with application number 202221565978.9 discloses a distributor, a refrigeration cycle system and a refrigeration device. The distributor includes a shell, a flow cavity is formed inside, and the opposite ends of the shell are respectively formed with a fluid inlet and a fluid outlet connected to the flow cavity; a filter is installed in the flow cavity, and the filter is flat and located between the fluid inlet and the fluid outlet. The distributor can simplify the manufacturing process of the distributor and reduce the processing time and processing cost of the distributor by arranging the filter inside the shell. By arranging the filter in the flow cavity inside the shell, impurities can also be collected, the noise caused by the pulse and impact of the refrigerant is reduced, and the blockage of the pipeline is avoided. However, the filter in the existing distributor is directly installed inside the distributor shell, so there is still the problem of inconvenient assembly, which not only increases the production cost of the distributor, but also needs to be disassembled and replaced as a whole after the distributor filter is blocked, and it is impossible to replace and clean only the filter on the distributor, which is not conducive to reducing the maintenance difficulty of the refrigeration system.

[0031] Embodiment 1

[0032] Figure 1 This is a schematic diagram of the structure of a distributor for a refrigeration system according to the first embodiment of the utility model. Figure 1 and Figure 2A distributor for a refrigeration system comprises a shell 1, one end of the shell 1 is provided with an inlet, the other end is provided with an outlet 3, at least two outlets 3 are provided, a connecting assembly is provided at a position corresponding to one end of the inlet on the shell 1; the connecting assembly comprises a connecting piece 2 and a filter basket 5, one end of the connecting piece 2 is provided with an assembly groove 4 matched with the shell 1, and the other end is provided with an installation groove for installing a pipeline, and the installation groove is communicated with the assembly groove 4; the open end of the filter basket 5 is provided with a curling portion 7 matched with the installation groove, and the other end extends into the shell through the shell inlet, and there is a matching gap between the shell 1 and the connecting piece 2 that matches the curling portion 7, and the end of the filter basket 5 extending into the shell is provided with a plurality of filter holes 6 for connecting the assembly groove and the shell.

[0033] For example, the connector 2 and the housing 1 can be plugged and fixed, thereby reducing the difficulty of installing and removing the connector. By adopting a split structure, the assembly difficulty of the dispenser is reduced, which is beneficial to the subsequent maintenance and use of the dispenser.

[0034] In actual use, before installing the connecting piece 2, the operator can first install the filter basket 5 on the connecting piece 2 or the shell 1, and then connect the connecting piece 2 with the shell 1. After the connecting piece 2 is connected to the shell 1, the curled portion 7 is elastically deformed by force, so that the curved surface on the curled portion 7 can stably fit the connecting piece and the shell surface. At this time, the curled portion 7 on the filter basket 5 can also play a certain sealing role in the connection between the connecting piece and the shell, which is beneficial to improve the stability and sealing of the connection between the connecting piece and the shell.

[0035] The structural diagram of a distributor for a refrigeration system described in this embodiment adopts a split structure and utilizes a connector to cooperate with the shell to achieve installation and fixation of the filter basket, thereby reducing the difficulty of assembling the distributor.

[0036] Embodiment 2

[0037] Figure 3 This is a schematic diagram of the structure of a distributor for a refrigeration system according to the second embodiment of the present utility model. Figure 3 This embodiment is optimized based on the previous embodiment, and the specific optimization is as follows:

[0038] A recessed portion 10 cooperating with the filter basket 5 is provided at a position corresponding to the filter basket 5 on the housing 1, and a bent portion 11 cooperating with the recessed portion 10 is provided at a position corresponding to the assembly groove on the connector 2. By providing the recessed portion 10 at a position corresponding to the filter basket 5 on the housing, the recessed portion 10 can support the side of the filter basket, thereby limiting the filter basket, preventing the filter basket from shaking or deforming when the dispenser is used, and ensuring that the filter basket 5 can continue to play a stable filtering role. In addition, by providing the bent portion 11 cooperating with the recessed portion 10 on the connector, and utilizing the bent portion 11 to cooperate with the recessed portion 10, the stability of the connection between the connector 2 and the housing 1 can be further improved, preventing the connector from being separated from the housing when the dispenser is installed or used.

[0039] Exemplarily, the connector 2 and the housing 1 are both cylindrical structural members, and the two are coaxially arranged. Correspondingly, the filter basket 5 is also a cylindrical structural member, and the filter basket is coaxially arranged with the connector. Among them, the recessed portion 10, the curved portion 11 and the curled portion 7 are all annular structures, and are coaxially arranged with the connector. By adopting a cylindrical connector, a housing, and a filter basket, and arranging the three coaxially, it is beneficial to improve the stability of the connection of each component and ensure the sealing of the connection between the connector and the housing.

[0040] In actual application, the operator can first install the filter basket and the connector on the shell, and then use extrusion equipment or other existing equipment to extrude corresponding curved portions and recessed portions on the connector and the shell, thereby achieving quick assembly of the connector and the shell, which is also conducive to further improving the stability and sealing of the connection between the connector and the shell.

[0041] Figure 4 This is a schematic diagram of the structure of a filter basket in a distributor for a refrigeration system according to the second embodiment of the present invention. Figure 4 The end of the filter basket 5 extending into the housing is provided with a conical surface 14 that matches the recessed portion, and the large diameter end of the conical surface 14 is arranged toward the open end of the filter basket 5. By arranging the conical surface 14 on the filter basket 5 and arranging the large diameter end of the conical surface 14 toward the open end of the filter basket, when the connector and the housing are extruded by an extrusion device, the recessed portion on the housing can match the inclined surface of the conical surface, thereby applying a force toward the connector to the filter basket 5, ensuring that the curled portion on the filter basket can better fit the inner wall of the assembly groove, and achieving sealing of the connection between the connector and the housing.

[0042] Optionally, a conical portion 12 is provided at one end of the filter basket 5 extending into the housing, the tip of the conical portion 12 is arranged toward the open end of the filter basket, and the outlet of the housing is evenly arranged around the conical portion 12. Exemplarily, the filter holes 6 can be round holes or strip holes, and those skilled in the art can select filter holes 6 of appropriate shapes and apertures according to actual needs to filter impurities in the refrigerant, which will not be described in detail here.

[0043] In actual application, two, four or more outlets on the shell can be evenly arranged corresponding to the four sides of the conical portion 12. By arranging the outlets on the shell corresponding to the four sides of the conical portion 12, the conical portion 12 can play a good diversion and guiding role for the refrigerant, guiding the refrigerant to flow quickly to the outlets on the shell, which is beneficial to improving the distribution effect of this distributor.

[0044] Figure 5 This is a schematic diagram of the structure of a connector in a distributor for a refrigeration system according to the second embodiment of the present utility model. Figure 5 , a protrusion 13 that matches the inner side of the filter basket is provided at a position corresponding to the assembly groove 4 on the connector 2. Exemplarily, the protrusion 13 is an annular structure, and the protrusion 13 is coaxially arranged with the connector 2. By providing the protrusion 13 that matches the inner side of the filter basket on the connector 2, the protrusion 13 can play a good limiting role on the filter basket, avoid excessive deformation of the filter basket, and ensure that the curled portion on the filter basket can continuously and stably fit with the connector and the housing to achieve a sealing effect.

[0045] Optionally, a through hole 9 for connecting the assembly groove 4 and the installation groove 8 is provided in the connector 2, and the aperture of the through hole 9 is smaller than the inner diameter of the assembly groove 4 and the installation groove 8. By providing the through hole 9 in the connector, the external pipeline can be connected with the distributor, and by providing the through hole 9 with an aperture smaller than the inner diameter of the assembly groove and the installation groove, it can be avoided that the pipeline or the filter basket is inserted into the through hole 9 due to the operator's misoperation, causing the distributor to be blocked, thereby reducing the difficulty of assembling the distributor.

[0046] In this embodiment, a recessed portion is provided on the housing at a position corresponding to the filter basket, and a curved portion is provided on the connector to cooperate with the recessed portion. The cooperation between the recessed portion and the curved portion can not only improve the stability of the connection between the connector and the housing, but also prevent the connector and the housing from being separated when the dispenser is installed or used. In addition, the recessed portion can cooperate with the conical surface portion on the filter basket to achieve positioning and limiting of the filter basket, thereby ensuring the stability of the filter basket, and further improving the stability and sealing of the connection between the connector and the housing.
