Description

Technical Field

[0001] This application relates to the field of gas-liquid separator technology, and more specifically to a horizontally externally connected gas-liquid separator. Background Technology

[0002] In automotive thermal management systems, the gas-liquid separator is a crucial component, located between the evaporator and the compressor. The working principle of the gas-liquid separator is as follows: when the refrigerant mixture enters the separator, its expansion velocity decreases, causing the liquid mixture to flow into the bottom of the separator, while the gaseous portion exits through the outlet and is delivered to the external compressor. It's important to note that the liquid mixture includes both refrigerant and liquid refrigerant. During the gas discharge process, the refrigerant is drawn back into the compressor, achieving refrigerant oil recycling and preventing compressor damage caused by insufficient lubrication.

[0003] Patent document (CN218296320U) discloses a gas-liquid separator for an automotive air conditioning heat pump system, including an upper cover and a body. The upper cover has an air inlet and an air outlet. It should be noted that the gas-liquid separator is normally arranged vertically. Since the air inlet and the air outlet are located at the top of the gas-liquid separator of the automotive air conditioning heat pump system, existing external pipes are mostly arranged vertically to connect to the air inlet and the air outlet. That is, the arrangement of the external pipes is parallel to the central axis of the body. This external connection method is defined as vertical external connection. The installation scenario adapted to vertical external connection requires a higher height. In some vehicle models with height restrictions, the external pipes are arranged horizontally. At this time, a gas-liquid separator with a horizontally arranged interface is needed.

[0031] Schematic diagram of an externally connected gas-liquid separator, reference Figures 1 to 6According to a preferred embodiment of the present invention, a horizontally connected gas-liquid separator includes a horizontally connected connector 10, a housing 20, and a cylindrical assembly 30.

[0032] Specifically, such as Figures 1 to 4 The horizontal external connector 10 includes a first inlet protrusion 101, a first outlet protrusion 102, a second inlet protrusion 103, a second outlet protrusion 104, an inflow channel 105, an outflow channel 106, and a plurality of first connecting holes 107. The first inlet protrusion 101 and the second outlet protrusion 104 are located at one end of the horizontal external connector 10, and the first outlet protrusion 102 and the second inlet protrusion 103 are located at the other end of the horizontal external connector 10. The two ends of the inflow channel 105 are respectively connected to the first inlet protrusion 101 and the first outlet protrusion 102, and the two ends of the outflow channel 106 are respectively connected to the first inlet protrusion 101 and the first outlet protrusion 102. The second inlet protrusion 103 and the second outlet protrusion 104 are connected. The first connecting hole 107 is located at one end of the horizontal external connector 10 with the first outlet protrusion 102. The first inlet protrusion 101 and the second outlet protrusion 104 are both arranged horizontally. The inflow channel 105 and the outflow channel 106 each include a vertical section, a longitudinal section and a transverse section. The two ends of the longitudinal section are connected to the vertical section and the transverse section respectively. The longitudinal section is also arranged perpendicular to the vertical section and the transverse section. The vertical section is close to the first outlet protrusion 102 and the transverse section is close to the first inlet protrusion 101.

[0033] It should be noted that the external gas-liquid mixture of refrigerant flows in from the first inlet protrusion 101, flows out from the first outlet protrusion 102 along the inflow channel 105, and flows into the outer casing 20. Subsequently, the gaseous portion of the external gas-liquid mixture of refrigerant passes through the cylindrical assembly 30, flows into the second inlet protrusion 103, and flows out from the second outlet protrusion 104 along the outflow channel 106. The liquid portion of the external gas-liquid mixture of refrigerant includes refrigeration oil and liquid refrigerant. Because the refrigeration oil has a higher density than the liquid refrigerant, it falls to the bottom of the outer casing 20 more quickly and accumulates for recovery. At the same time, because the viscosity of the liquid refrigerant will be lower than that of the refrigeration oil due to partial solidification at the operating temperature of the gas-liquid separator, when the separated gas flows through the cylindrical assembly 30, a pressure difference is easily generated in the corresponding area, and the low-pressure gas will be released. High-viscosity, high-flow-rate refrigerant oil is extracted and discharged along with the gas through the second inlet protrusion 103, the outlet channel 106, and the second outlet protrusion 104, and sent to an external compressor. Furthermore, the first connecting hole 107 provides a connection between the horizontal external connector 10 and the housing 20. Additionally, by providing the horizontal external connector 10 and arranging the first inlet protrusion 101 and the second outlet protrusion 104 horizontally, it can be connected to horizontally arranged external pipelines compared to existing technologies. Moreover, in vehicles with vertical external connections, the bolts connecting the first connecting hole 107 to the housing 20 can be loosened directly, and the horizontal external connector 10 can be removed, leaving the housing 20 and the cylinder assembly 30 intact, thus enabling installation with higher adaptability and greater flexibility.

[0034] Specifically, such as Figure 2 and Figure 5 As shown, the outer casing 20 includes a cylindrical body 201 and a top cover 202. The cylindrical body 201 has a cavity 2011. The top cover 202 is connected to the cylindrical body 201 and closes the opening of the cavity 2011. The top cover 202 has a first insertion hole 2021, a second insertion hole 2022, and a plurality of second connecting holes 2023. The first insertion hole 2021 and the second insertion hole 2022 penetrate the top cover 202 in the height direction. The first outlet protrusion 102 extends into the first insertion hole 2021, and the second inlet protrusion 103 extends into the second insertion hole 2022. The first connecting hole 107 and the second connecting hole 2023 correspond one-to-one and are connected to each other by bolts.

[0035] In addition, such as Figure 2As shown, the cylindrical assembly 30 includes an inner cylinder 301 and an outer cylinder 302. The outer cylinder 302 is sleeved on the outside of the inner cylinder 301, and a first gap channel 3021 is formed between the inner wall of the outer cylinder 302 and the outer wall of the inner cylinder 301. The top of the outer cylinder 302 communicates with the second insertion hole 2022. A second gap channel 3022 is formed between the bottom of the inner cylinder 301 and the bottom wall of the outer cylinder 302. A third gap channel 3023 is formed between the top of the outer cylinder 302 and the upper cover 202.

[0036] It should be noted that after the gaseous portion of the external gas-liquid mixed refrigerant flows into the concave cavity 2011, it flows into the first gap channel 3021 from the third gap channel 3023, and after flowing through the second gap channel 3022, it flows from bottom to top along the inner hole channel of the inner cylinder 301 to the second inlet protrusion 103, and is discharged outward to the external compressor along the outflow channel 106 and the second outlet protrusion 104; while the refrigeration oil and liquid refrigerant fall into the bottom of the concave cavity 2011, wherein the refrigeration oil will be drawn into the second gap channel 3022 under the action of pressure difference when the above-mentioned separated gas passes through the second gap channel 3022, and the refrigeration oil and separated gas move upward in the form of "oil mist" and are sent to the external compressor.

[0037] Furthermore, since the amount of gas discharged per unit time is greatly affected by the radial dimensional accuracy of the inner cylinder 301 and the outer cylinder 302, in order to improve the yield rate, such as Figure 2 and Figure 6 As shown, the inner cylinder 301 has several fine-tuning holes 3011 at one end near the upper cover 202, and the horizontally connected gas-liquid separator also includes several plugs 3012, which are removable and inserted into the fine-tuning holes 3011.

[0038] It should be noted that the plug 3012 includes fully enclosed (i.e., no through-hole) models and models with different through-hole sizes. When the horizontally connected gas-liquid separator is inspected by the testing device, if its gas output per unit time is lower than the rated gas output, the plug 3012 can be completely pulled out or the radial size of the through-hole on the plug 3012 can be enlarged so that the separated gas can flow directly into the inner cylinder 301 along the fine-tuning hole 3011 and be discharged, shortening the gas flow path and increasing the gas flow rate into the inner cylinder 301 in the same time. Similarly, when the gas output per unit time of the horizontally connected gas-liquid separator is lower than the rated gas output, the plug 3012 with a smaller through-hole size or the fully enclosed plug 3012 can be selected to achieve fine-tuning of the gas flow rate into the inner cylinder 301 in the same time. Compared with the prior art, this helps to improve the yield rate.

[0039] In addition, to prevent the blockage 3012 from falling into the inner channel of the inner cylinder 301, such as Figure 6 As shown, the fine-tuning hole 3011 is a conical hole, and the end of the conical hole away from the central axis of the inner cylinder 301 is the end with a larger diameter. The plug 3012 is generally truncated cone-shaped.

[0040] Furthermore, such as Figure 2 As shown, the horizontally connected gas-liquid separator also includes a baffle 40, which is located at one end of the third gap channel 3023 near the upper cover 202. The top wall of the baffle 40 has a fourth gap channel 401 between it and the first insertion hole 2021, and the side wall of the baffle 40 has a fifth gap channel 402 between it and the side wall of the cavity 2011.

[0041] It should be noted that by setting the baffle 40, the external gas-liquid mixture of refrigerant is effectively prevented from falling directly into the first gap channel 3021. That is, when the gas part enters the cavity 2011, it flows along the fourth gap channel 401 to the fifth gap channel 402, and then along the first gap channel 3021, the second gap channel 3022, and the inner hole channel of the inner cylinder 301 from bottom to top to the second inlet protrusion 103; while the liquid part will slide down along the baffle 40 to the side wall or the area near the side wall of the cavity 2011, and finally accumulate at the bottom of the cavity 2011.

[0042] Furthermore, to facilitate the absorption of moisture from the liquid portion, such as Figure 2 As shown, the horizontally connected gas-liquid separator also includes a water-absorbing element 3024, which is fixedly installed in the middle section of the outer cylinder 302. The water-absorbing element 3024 is further implemented as a molecular sieve.

[0043] Furthermore, to provide conditions for extracting the refrigeration oil, such as... Figure 2 As shown, the horizontally connected gas-liquid separator also includes a filter assembly 50, which is located at the bottom of the outer cylinder 302. The filter assembly 50 includes a frame 501 and a filter screen 502. The frame 501 includes a bottom surface 5011, a plurality of vertical columns 5012 arranged in a circular array, and a bottom cylinder 5013. The vertical columns 5012 are arranged vertically, and both ends of the vertical columns 5012 are fixedly connected to the bottom surface 5011 and the bottom cylinder 5013, respectively. The fixed connection method includes, but is not limited to, injection molding. The bottom cylinder 5013 closes the bottom cavity of the outer cylinder 302. A filter screen 502 is provided between each pair of adjacent vertical columns 5012. The bottom cylinder 5013 has an oil passage hole 5014.

[0044] It should be noted that by setting the filter screen 502, large particulate impurities in the refrigeration oil can be filtered out. By setting the bottom cylinder 5013, the bottom of the outer cylinder 302 is sealed. That is, at this time, the area between the bottom of the inner cylinder 301 and the bottom cylinder 5013 is the second gap channel 3022. When the separated gas flows through the second gap channel 3022, the refrigeration oil passes through the oil passage hole 5014 under pressure difference and is drawn into the second gap channel 3022 and mixes with the separated gas to form an "oil mist".

[0045] Furthermore, to achieve the fixation of the outer shell 20 to the external vehicle body, such as... Figure 1 and Figure 2 As shown, the side wall of the outer casing 20 has a mounting base 203, and the mounting base 203 has a mounting hole 2031, through which a bolt is screwed into the mounting hole 2031 to connect with the outer vehicle body threadedly.

[0046] Furthermore, to secure the other end of the horizontal external connector 10, such as... Figure 4 As shown, the horizontal external connector 10 has a third connection hole 108 at the end opposite to the first connection hole 107, and the third connection hole 108 is provided to facilitate bolt connection with the external vehicle body.

[0047] Furthermore, to improve sealing, such as Figure 4 As shown, the sidewalls of the first inlet protrusion 101, the first outlet protrusion 102, the second inlet protrusion 103, and the second outlet protrusion 104 each have a plurality of annular grooves 1011, and a sealing ring is fitted inside each of the annular grooves 1011.

[0048] In summary, the horizontally connected gas-liquid separator described in the embodiments of this application is explained, which provides advantages such as a horizontally arranged interface for the horizontally connected gas-liquid separator.

[0049] It is worth mentioning that, in the embodiments of this application, the horizontally connected gas-liquid separator has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the horizontally connected gas-liquid separator provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0050] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The function and structural principle of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from these principles.
