Description

Technical Field

[0001] This utility model relates to the field of air conditioning pipe technology, and in particular to a manifold and distribution pipe. Background Technology

[0002] In air conditioning systems, multiple pipes are typically used for distribution or collection. For example, at the inlet of a heat exchanger, multiple branch pipes need to be installed on the distributor so that the refrigerant can flow into the heat exchanger through the branch pipes. At the outlet of the heat exchanger, multiple branch pipes also need to be installed on the collector so that the refrigerant can be collected from the multiple branch pipes to the main pipe.

[0003] However, before entering the distributor, the refrigerant is usually in a state of mixed gas and liquid flow. Most current distributors only serve to distribute the refrigerant from the main pipe to multiple branch pipes, making it difficult to ensure that the gas and liquid refrigerant can be evenly mixed and distributed to each branch pipe. This results in an unsatisfactory refrigerant distribution effect, which can easily affect the subsequent use of the refrigerant.

[0004] Furthermore, in the existing air conditioning system piping, filters and silencers need to be welded to the adjacent pipes of the distributor or collector in order to filter out impurities in the refrigerant and reduce the noise generated by the refrigerant circulating in the pipes. However, the installation of filters and silencers increases the processing cost of the product and increases the production burden of the enterprise. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a current collection and distribution pipe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A flow distribution pipe includes a pipe body with sealing plates installed at both ends. A gasket is fixedly installed inside the pipe body, which divides the interior of the pipe body into a flow distribution cavity and a flow collection cavity. A branch pipe hole corresponding to the position of the flow distribution cavity and a main pipe hole corresponding to the position of the flow collection cavity are opened on the side wall of the pipe body. A plurality of through holes connecting the flow distribution cavity and the flow collection cavity are opened on the gasket.

[0008] Preferably, the volume of the diversion cavity is larger than the volume of the collection cavity.

[0009] Preferably, the outer periphery of the tube is provided with an inwardly recessed fixing part, which is pressed and fixed to the outer periphery of the gasket.

[0010] Preferably, the outer periphery of the gasket is provided with an annular groove that matches the fixing part, and the fixing part is engaged inwardly on the annular groove.

[0011] Preferably, a filter screen is provided inside the collection cavity, and the filter screen is fixed to the gasket.

[0012] Preferably, the outer periphery of the tube is provided with an inwardly recessed fixing part two, which presses against and fixes the filter screen inward.

[0013] Preferably, the filter screen is provided with a retaining ring that abuts against the side wall of the gasket, and the fixing part engages with the retaining ring inward.

[0014] Preferably, the tube body, gasket, and filter screen are made of copper.

[0015] Preferably, the tube body, gasket, and filter screen are made of stainless steel.

[0016] The beneficial effects of this utility model are:

[0017] 1. By installing gaskets inside the pipe and opening multiple through holes on the gaskets to connect the distribution chamber and the collection chamber, the flow of refrigerant is distributed through the through holes. That is, the refrigerant flowing into the pipe from the main pipe is distributed through the through holes and then mixed in the distribution chamber, so that the refrigerant can be more fully mixed and then transported out through the branch pipe holes, thereby improving the effect of refrigerant mixing and distribution and ensuring the subsequent performance of the refrigerant.

[0018] 2. By designing the volume of the distribution cavity to be larger than that of the collection cavity, the multiple streams of refrigerant jetted into the distribution cavity can be mixed more evenly, thus providing more space for refrigerant mixing and ensuring the uniformity of refrigerant mixing.

[0019] 3. By opening multiple through holes on the gasket for refrigerant flow, the noise of the flowing refrigerant is reduced when it flows through the through holes, thus reducing the noise of the refrigerant circulating in the pipe.

[0020] 4. A filter screen is installed inside the pipe to filter impurities in the refrigerant circulating inside the pipe. By rationally integrating the filter screen and gasket into the pipe, the overall production and processing cost of the product can be reduced.

[0021] 5. By placing the filter screen on one side of the refrigerant collection chamber, the filter screen can buffer the refrigerant flow when it flows into the chamber, thus preventing multiple rapidly flowing refrigerant streams from converging and causing flow turbulence, thereby ensuring the stability and efficiency of refrigerant collection.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] like Figures 1-4 As shown, a flow distribution pipe includes a pipe body 1, with sealing plates 11 installed at both ends of the pipe body 1. Two sealing plates 11 are welded and fixed to both ends of the pipe body 1 to seal both ends of the pipe body 1. A gasket 2 is fixedly provided inside the pipe body 1. The outer periphery of the gasket 2 is attached to the inner wall of the pipe body 1. The gasket 2 divides the inside of the pipe body 1 into a flow distribution cavity 12 and a flow collection cavity 13.

[0030] The side wall of the pipe body 1 is provided with branch pipe holes 14 corresponding to the position of the diversion cavity 12 and main pipe holes 15 corresponding to the position of the collection cavity 13. There are multiple branch pipe holes 14, and branch pipes are welded to each branch pipe hole 14. Main pipes are welded to the main pipe holes 15. The refrigerant flows through the main pipe, pipe body 1 and branch pipes for diversion or through the branch pipes, pipe body 1 and main pipes for collection.

[0031] The gasket 2 has multiple through holes 21 that connect the diversion chamber 12 and the collection chamber 13. The flow of refrigerant is diverted through the through holes 21. That is, the refrigerant flowing into the pipe body 1 from the main pipe and the main pipe hole 15 is diverted through the through holes 21 and then mixed in the diversion chamber 12, so that the refrigerant can be more fully mixed. The refrigerant is then transported out through the branch pipe hole 14 and the branch pipe, thereby improving the effect of refrigerant mixing and diversion and ensuring the subsequent performance of the refrigerant.

[0032] The volume of the diversion cavity 12 is larger than that of the collection cavity 13, which allows the multiple streams of refrigerant jetted into the diversion cavity 12 to mix more evenly, thus providing more space for refrigerant mixing and ensuring the uniformity of refrigerant mixing.

[0033] Furthermore, by creating multiple through holes 21 on the gasket 2 for refrigerant flow, the refrigerant can be silenced when it flows through the through holes 21, thereby reducing the noise of the refrigerant circulating in the pipeline.

[0034] A filter screen 3 is provided inside the collection cavity 13. The filter screen 3 is positioned facing the main pipe hole 15 and is fixed to the gasket 2.

[0035] Furthermore, the outer periphery of the tube body 1 is provided with an inwardly recessed fixing part 16, which is distributed in a ring around the outer periphery of the tube body 1. The outer periphery of the gasket 2 is provided with an annular groove 22 that is adapted to the fixing part 16. The fixing part 16 is engaged inwardly with the annular groove 22, that is, the fixing part 16 is pressed and fixed on the outer periphery of the gasket 2 to fix the gasket 2 inside the tube body 1. The fixing part 16 is engaged in the annular groove 22 to improve the sealing between the outer periphery of the gasket 2 and the inner wall of the tube body 1, so as to prevent the refrigerant from flowing from the gap between the gasket 2 and the tube body 1.

[0036] The outer periphery of the tube body 1 is provided with an inwardly recessed fixing part 2 17, which is distributed in a ring around the outer periphery of the tube body 1. The filter screen 3 is provided with a retaining ring 31 that abuts against the side wall of the gasket 2. The fixing part 2 17 engages with the retaining ring 31 inward, that is, the fixing part 2 17 presses against and fixes the filter screen 3 inward.

[0037] In this embodiment, the fixing method of fixing part 16 and fixing part 2 17 can be snap-fit ​​fixing, pressure ring fixing or dot fixing. The fixing part 16 and fixing part 2 17 fix the gasket 2 and the filter screen 3 respectively by inward deformation. For ease of understanding, this embodiment uses pressure ring fixing as an example.

[0038] By placing the filter screen 3 inside the pipe body 1, impurities in the refrigerant circulating inside the pipe body 1 are filtered out. Furthermore, by rationally integrating the filter screen 3 and the gasket 2 into the pipe body 1, the overall production and processing costs of the product are reduced, thereby increasing the company's profits.

[0039] Furthermore, by placing the filter 3 on one side of the collection cavity 13, when the refrigerant flows into the collection cavity 13, the filter 3 can buffer the flowing refrigerant to a certain extent, so as to avoid multiple rapidly flowing refrigerants from flowing together and causing flow velocity disturbance, thereby ensuring the stability and efficiency of refrigerant flow.

[0040] The tube body 1, gasket 2, and filter screen 3 can be made of copper, and in order to further reduce the cost of the product, the tube body 1, gasket 2, and filter screen 3 can be made of stainless steel.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
