Description

Technical Field

[0001] This application relates to the field of compressor equipment technology, and in particular to a multi-pipe socket type liquid receiver for air conditioning compressors. Background Technology

[0002] The air conditioner compressor is the core component of the air conditioning refrigeration system. Its core function is to transfer heat by compressing and circulating the refrigerant, thereby achieving the purpose of cooling or heating. The compressor achieves heat "transportation" through mechanical compression, and its performance directly determines the air conditioner's cooling / heating effect and energy consumption level. Furthermore, the air conditioner compressor's receiver-refrigerant tank is an important component of the refrigeration system, mainly used for storing high-pressure refrigerant liquid, separating gas and liquid, filtering impurities, and also serving as a pressure buffer and noise reduction mechanism. Because the air conditioner compressor primarily functions by compressing and circulating the refrigerant, the stability and airtightness of the connection structure of the connecting pipes located at its inlet and outlet are extremely important.

[0003] However, due to defects in welding technology, the existing welding structure for the connecting pipes on the air conditioner compressor, while achieving a stable weld and meeting airtightness requirements, not only requires more materials but also has a shorter lifespan and necessitates frequent maintenance. This structure not only wastes materials but also increases maintenance costs during the later use of the air conditioner. Utility Model Content

[0004] In order to address the defects of the pipe welding structure when connecting air conditioning compressors to other structures in the prior art, and to improve the stability of the welding structure while saving materials, this application provides a multi-pipe socket type air conditioning compressor liquid storage tank.

[0005] The technical solution for a multi-pipe socket-type air conditioning compressor liquid receiver provided in this application is as follows:

[0006] A multi-pipe socket-type air conditioning compressor liquid storage tank includes a tank body for compressing and transporting refrigerant. The tank body has an inlet and an outlet that are both connected to the interior. A sleeve is integrally connected to both the inlet and the outlet. An internal tube is inserted into the tank body through the sleeve. A stepped groove is formed on the inner wall of the sleeve. One end of the internal tube is adapted to the size of the stepped groove. A connecting tube is inserted near the end of the internal tube near the sleeve. A sleeve fitting is fitted on the outside of the connecting tube. The end of the sleeve fitting and the end of the internal tube are located on the same plane. A limiting structure is provided on the internal tube to prevent the internal tube from rotating arbitrarily within the tank body.

[0007] Optionally, the limiting structure includes several strip grooves respectively spaced circumferentially on the tank at the inlet and outlet positions, and several strip buckles respectively spaced circumferentially on the outer side of the end of the internal tube near the inlet or outlet. One end of each of the strip grooves is connected to the port of the inlet or outlet of the tank. Each of the strip buckles corresponds to one of the strip grooves and is slidably engaged in the strip groove.

[0008] Optionally, the wall thickness of the strip buckle is equal to the wall thickness of the inner tube, and a sliding groove is formed on the back side of each of the strip buckles in the inner tube. A plurality of sliding buckles are integrally connected to the end of the connecting tube along the circumferential direction. The plurality of sliding buckles correspond one-to-one with the sliding grooves and are slidably engaged in the plurality of sliding grooves respectively.

[0009] Optionally, the sleeve and the outer wall of the sleeve overlap and are fixedly connected.

[0010] Optionally, the end of the built-in tube is on the same plane as the end of the sleeve at the inlet or outlet position.

[0011] Optionally, the inner side of the built-in tube is provided with an annular groove that is connected to the other end of several sliding grooves away from the connecting tube. When the sleeve is fixedly connected to the sleeve, several of the sliding buckles are located in the annular groove.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. This application provides a liquid storage tank for a socket-type air conditioning compressor. The connection structure of the liquid storage tank pipeline is improved by the multi-pipeline socket connection structure, which also saves more material compared with the traditional pipeline connection structure.

[0014] 2. The connection structure of this application is simple and can realize the operation of completely filling the weld seam in the sleeve-type pipeline with solder, thereby improving the overall quality of the pipeline after welding. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a multi-pipeline socketed air conditioning compressor liquid storage tank.

[0022] Reference Figure 1 A multi-pipeline socketed air conditioning compressor liquid receiver tank includes a tank body 1, with an inlet 11 and an outlet 12 communicating with the interior of the tank body 1. The tank body 1 is equipped with a compression mechanism and a transport mechanism, which can compress the refrigerant and transport it to the high-pressure zone inside the air conditioner for heat absorption. Specifically, the tank body 1 has sleeves 13 integrally connected at both the inlet 11 and outlet 12 positions to facilitate connection to connecting pipes 3 for interconnection with other equipment.

[0023] Reference Figure 2 and Figure 4 An internal tube 2, with one end extending into the tank body 1, is inserted through the sleeve 13. A stepped groove 131 is formed within the sleeve 13, and the end of the internal tube 2 is sized to fit the stepped groove 131 for axial positioning. A connecting pipe 3 is fitted to one end of the internal tube 2 near the sleeve 13, and a sleeve pipe 4 is fitted to the other end of the connecting pipe 3. The end of the sleeve pipe 4 near the tank body 1 is on the same plane as the end of the sleeve 13.

[0024] Preferably, the outer wall of the sleeve 4 is coaxial with and coincides with the outer wall of the sleeve 13, so that the outer surface of the connection position between the tank 1 and the connecting pipe 3 is flat, smooth and tight, which is not only more aesthetically pleasing, but also prevents the two from being easily separated in case of accidental contact.

[0025] It should be noted that the connection structure between the built-in tube 2, the connecting tube 3 and the sleeve tube 4 in this application is fixed by welding, and the gaps between each part are filled with solder.

[0026] Preferably, in this application, the inlet 11 and outlet 12 on the tank body 1 are both located on the axis of the tank body 1, which makes the processing, assembly and welding of the liquid storage tank more convenient.

[0027] Reference Figure 2 and Figure 3Furthermore, a limiting structure 5 is provided on the built-in tube 2 to prevent the built-in tube 2 from rotating arbitrarily within the tank body 1 during welding, which would result in a weak weld. The limiting structure 5 specifically includes several strip-shaped grooves 51 evenly spaced along the circumference at the inlet 11 and outlet 12 positions on the tank body 1, and several strip-shaped buckles 52 respectively connected along the circumference at intervals to one end of the built-in tube 2 near the sleeve 13. One end of each of the strip-shaped grooves 51 is connected to the port at the inlet 11 or outlet 12 position on the tank body 1, and each of the strip-shaped buckles 52 corresponds to one of the strip-shaped grooves 51 and is slidably engaged within the strip-shaped grooves 51.

[0028] When processing the liquid storage tank, the inner tube 2 is first inserted into the sleeve 13, then the connecting tube 3 is inserted into the inner tube 2, and finally the sleeve pipe 4 is installed and welded on the outer sleeve of the connecting tube 3, so that the end of the sleeve pipe 4 is completely connected to the end of the sleeve 13, forming a multi-pipeline sleeve welded structure.

[0029] Furthermore, the wall thickness of the strip buckle 52 is equal to the wall thickness of the inner tube 2, meaning that the strip buckle 52 is integrally formed during the manufacturing of the inner tube 2, rather than being cut out. This structure makes the inner tube 2 more stable and prevents structural damage during connection.

[0030] With the above structure, the inner side of the inner tube 2 has corresponding grooves 21 formed on the back side of the strip buckles 52. The end of the connecting tube 3 near the tank body 1 is integrally connected with several sliding buckles 31, which slide and engage in the grooves 21 to limit the rotation of the connecting tube 3. This makes the welding between the connecting tube 3 and the inner tube 2, as well as between the connecting tube 3 and the sleeve tube 4, more convenient.

[0031] Reference Figure 3 Preferably, the end face of the inner tube 2 near the sleeve 4 is also located on the same plane as the sleeve 4. This structure not only allows for a larger contact area between the end face of the sleeve 4 and the welding surface during welding to improve the stability of the welded structure, but also allows for axial restraint of the inner tube 2 using the sleeve 4 and the solder.

[0032] Reference Figure 3 and Figure 4 Furthermore, an annular groove 22 is provided on the inner side of the built-in tube 2, and the annular groove 22 is connected to the other end of the sliding groove 21 away from the connecting tube 3. When the sleeve tube 4 is welded to the end of the sleeve 13, several sliding buckles 31 enter the sliding groove 21. At this time, the solder can fully fill the sliding groove 21 and the annular groove 22, making the welding position a solid structure, further improving the airtightness and structural stability of the welding position.

[0033] The implementation principle of a multi-pipeline socketed air conditioning compressor liquid receiver tank in this application embodiment is as follows:

[0034] This application realizes a multi-pipeline sleeved welding structure between the tank body 1 and the connecting pipe 3 by using the built-in pipe 2, connecting pipe 3 and sleeve pipe 4 on the sleeve 13 at the inlet 11 and outlet 12 positions of the tank body 1. This not only improves the airtightness and welding stability of the pipeline welding position, but also saves materials.

[0035] Furthermore, by setting a mutual limiting structure 5 between the connecting pipe 3, the built-in pipe 2, and the sleeve pipe 4, this application effectively reduces the difficulty of welding operations, making the operation more convenient and effectively improving the economic practicality of the welding structure of this application.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
