[0034] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.

[0035] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below. Figures 1-6 The gas-liquid separator 100 according to the embodiments of the present application is described below, which can be applied to a vehicle.

[0036] In combination with Figures 1-6 As shown in the drawings, the gas-liquid separator 100 according to the embodiments of the present application can mainly include: a housing 10, a first partition 20 and a second partition 30.

[0037] The first partition 20 is arranged in the housing 10, the first partition 20 is at least partially arc-shaped, both ends of the first partition 20 are connected with the housing 10 and divide the internal space of the housing 10 into a first space 110 and a second space 120, the first space 110 and the second space 120 are in communication, and the second space 120 is adapted to be in communication with the inlet of the compressor.

[0038] And, the second partition plate 30 is connected between the shell 10 and the first partition plate 20, the second partition plate 30 divides the first space 110 into a first cavity 111 and a second cavity 112, the first cavity 111 and the second cavity 112 are communicated, a plurality of baffles 40 are arranged on the side surface of the second partition plate 30 facing the first cavity 111, the plurality of baffles 40 are arranged at intervals and form flow channels 1111, the flow channels 1111 are adapted to be communicated with the outlet of the evaporator and the outlet of the compressor.

[0039] Specifically, the first partition plate 20 divides the internal space of the shell 10 in the radial direction into a first space 110 and a second space 120, the first space 110 and the second space 120 are communicated, and the second partition plate 30 further divides the first space 110 into a first cavity 111 and a second cavity 112, the first cavity 111 and the second cavity 112 are also communicated.

[0040] By arranging a plurality of baffles 40 on the side surface of the second partition plate 30 facing the first cavity 111, the plurality of baffles 40 are arranged at intervals and form flow channels 1111 together with the shell 10, the first partition plate 20 and the second partition plate 30, the flow channels 1111 are adapted to be communicated with the outlet of the evaporator and the outlet of the compressor. In this way, the refrigerant from the evaporator and the compressor can enter the gas-liquid separator 100 and flow in the flow channels 1111. The baffles 40 in the flow channels 1111 can change the flow direction of the refrigerant multiple times and increase the length of the flow path of the refrigerant.

[0041] On the one hand, this can increase the flow resistance of the refrigerant and reduce the flow rate of the refrigerant, thereby avoiding the rapid flow sound of the refrigerant and improving the NVH performance of the vehicle.

[0042] On the other hand, when the refrigerant flows through the baffles 40, the gaseous refrigerant is more likely to change direction and continue to advance along the flow channels 1111 by bypassing the baffles 40 due to its lower density. The liquid refrigerant, due to its higher density and greater inertia, will directly hit the baffles 40 and be captured, and further flow down the surface of the baffles 40 under the action of gravity and collect, thereby achieving gas-liquid separation.

[0043] And it can be understood that, since the first cavity 111 and the second cavity 112 are communicated, the collected liquid refrigerant can further flow to the second cavity 112, and the second cavity 112 can store the refrigerant and adjust the circulation amount of the refrigerant under different working conditions.

[0044] In addition, since the first space 110 and the second space 120 are communicated, the separated gaseous refrigerant can further flow through the second space 120 to be communicated with the inlet of the compressor, thereby providing the compressor with pure gaseous refrigerant and avoiding the "liquid strike" phenomenon caused by the direct entry of liquid refrigerant into the compressor, ensuring the normal operation of the compressor.

[0045] Optionally, the housing 10 can be provided with a first inlet 11 and a second inlet 12, the first inlet 11 and the second inlet 12 are circumferentially spaced and communicated with the flow channel 1111, the first inlet 11 is adapted to be communicated with the outlet of the evaporator, and the second inlet 12 is adapted to be communicated with the outlet of the compressor. The housing 10 can also be provided with a first outlet 13 and a second outlet 14, the first outlet 13 is located at the upper end of the housing 10 and is adapted to be communicated with the inlet of the compressor, and the second outlet 14 is located at the lower end of the housing 10 and is adapted to be communicated with the second inlet 12.

[0046] In this way, through the arrangement of the first inlet 11, the second inlet 12, the first outlet 13 and the second outlet 14, the connection of the gas-liquid separator 100 and other components can be facilitated, and the operation of the staff can be facilitated.

[0047] And it can be understood that the high-temperature and high-pressure gaseous refrigerant flowing out of the compressor can be returned to the gas-liquid separator 100 through the second inlet 12, and the rapid flow of the refrigerant at the second inlet 12 can form a pressure difference, so that the liquid refrigerant in the second cavity 112 is sucked into the inside of the second inlet 12 through the second outlet 14, realizing jet flow guiding, so that more liquid refrigerant reenters the flow channel 1111 and evaporates and separates gaseous refrigerant, realizing the hot gas bypass function of the vehicle air conditioning system, and improving the stability and reliability of the vehicle air conditioning system. And in this way, without additionally setting a pump structure, the structure of the gas-liquid separator 100 and even the vehicle can be made more simple.

[0048] And a filter 70 can be arranged at the second outlet 14, the filter 70 can filter impurities in the refrigerant, avoid impurities flowing in the air conditioning system to block the expansion valve, etc., so as to improve the reliability of the air conditioning system of the gas-liquid separator 100 and even the vehicle.

[0049] Therefore, by arranging the first partition plate 20 and the second partition plate 30 in the housing 10, and arranging a plurality of baffles 40 on the side surface of the second partition plate 30 facing the first cavity 111, the plurality of baffles 40 are arranged at intervals and form the flow channel 1111, and the flow channel 1111 is adapted to be communicated with the outlet of the evaporator and the outlet of the compressor. In this way, not only can the rapid flow sound of the refrigerant be avoided, the NVH performance of the vehicle can be improved, but also gas-liquid separation can be realized, and the separation efficiency can be improved.

[0050] In some embodiments of the present application, in combination with Figure 2 and Figure 5As shown, the plurality of baffles 40 can include a plurality of first baffles 41 and a plurality of second baffles 42, one end of the first baffles 41 is connected with the shell 10, the other end of the first baffles 41 extends away from the shell 10 and is spaced apart from the first partition 20, one end of the second baffles 42 is connected with the first partition 20, the other end of the second baffles 42 extends away from the second partition 30 and is spaced apart from the shell 10. That is, the plurality of baffles 40 can be divided into two categories, which are the first baffles 41 and the second baffles 42, the first baffles 41 are a plurality of, and the second baffles 42 are a plurality of.

[0051] Further, the first baffles 41 and the second baffles 42 are sequentially and circumferentially spaced apart, the projections of the first baffles 41 and the second baffles 42 in the radial direction are connected or at least partially coincide, so that the arrangement of the plurality of baffles 40 can be optimized, and the plurality of first baffles 41 and the plurality of second baffles 42 can define the flow channel 1111 arranged in a bent manner.

[0052] In this way, the refrigerant will collide with the first baffles 41 and the second baffles 42 in sequence during the flow process, and under the blocking of the first baffles 41 and the second baffles 42, the flow direction is constantly changed, so that the refrigerant can be prevented from directly flowing through the radial gap between adjacent first baffles 41 and second baffles 42, thereby effectively avoiding the rapid flow sound of the refrigerant, and effectively improving the separation efficiency.

[0053] In combination Figure 2 As shown, the end of the first baffles 41 away from the shell 10 is at least partially arranged in a bent manner toward the direction opposite to the first direction, and the end of the second baffles 42 away from the first partition 20 is at least partially arranged in a bent manner toward the direction opposite to the first direction, wherein the first direction is the flow direction of the refrigerant in the flow channel 1111.

[0054] Specifically, the first direction is defined as the flow direction of the refrigerant in the flow channel 1111.

[0055] By arranging the end of the first baffles 41 away from the shell 10 in a bent manner at least partially toward the direction opposite to the first direction, the end of the first baffles 41 away from the shell 10 can block the refrigerant during the flow process, so as to avoid the refrigerant directly flowing out from the end of the first baffles 41, thereby ensuring that the refrigerant can continue to be fully impacted by the first baffles 41, and improving the separation efficiency.

[0056] By setting the second baffle 42 to be at least partially bent away from one end of the shell 10 towards a direction opposite to the first direction, the second baffle 42 can block the refrigerant away from the end of the shell 10 during the refrigerant flow, avoiding the refrigerant from flowing out directly from the end of the second baffle 42, so that the refrigerant can continue to impact the second baffle 42 sufficiently, improving the separation efficiency.

[0057] In the above, the structure design and arrangement of the baffle 40 can be optimized to improve the separation efficiency. In one specific embodiment of the present application, the baffle 40 is provided as seven, which can further optimize the number of baffle 40 and improve the separation efficiency.

[0058] In other embodiments of the present application, the baffle 40 is provided to extend in the radial direction and is connected to the shell 10 and the first partition 20 at both ends, and a plurality of first flow equalizing holes are provided on the baffle 40, and the plurality of first flow equalizing holes are provided at intervals. In this way, the flow channel 1111 is formed between the plurality of first flow equalizing holes provided on the plurality of baffle 40 at intervals. During the flow of the refrigerant, the refrigerant impacts the baffle 40, and the larger liquid refrigerant is intercepted on one hand because it cannot pass through the first flow equalizing hole, and on the other hand it is adhered to the baffle 40 due to the inertial effect and merged with other droplets to form larger droplets, while the smaller gaseous refrigerant can pass through smoothly, so that the effect of gas-liquid separation can be achieved, and the separation efficiency can be ensured.

[0059] In combination with Figs. 1-3, Figure 2 and Figure 5 As shown, the second partition 30 is further provided with a plurality of separation holes 32, the plurality of separation holes 32 are located in the flow channel 1111, and a part of the plurality of separation holes 32 are located at the lower end of the baffle 40 and extend along the extension direction of the baffle 40, and another part of the plurality of separation holes 32 are located at the lower end of the shell 10 and extend along the extension direction of the shell 10.

[0060] Specifically, the liquid droplets impacting on the baffle 40 form a layer of liquid film on the surface of the baffle 40, and as more liquid droplets continuously impact and adhere to this place, these liquid films gradually increase. At the same time, under the action of gravity, this layer of liquid film will flow downward along the surface of the baffle 40, and finally gather into larger droplets or liquid flow. The liquid droplets impacting on the shell 10 are the same.

[0061] By arranging the plurality of separation holes 32 on the second partition plate 30, and the plurality of separation holes 32 are all located in the flow channel 1111, and a part of the plurality of separation holes 32 is located at the lower end of the baffle plate 40 and is arranged along the extension direction of the baffle plate 40, and another part of the plurality of separation holes 32 is located at the lower end of the shell 10 and is arranged along the extension direction of the shell 10, so that the liquid refrigerant remaining on the surface of the baffle plate 40 can flow to the second cavity 112 through the separation hole 32, and the liquid refrigerant remaining on the surface of the shell 10 can flow to the second cavity 112 through the separation hole 32, thereby avoiding a large amount of liquid refrigerant accumulated in the flow channel 1111, avoiding that the liquid refrigerant separated out is taken away by the high-speed airflow again, and thereby realizing the separation and collection of the liquid refrigerant, and ensuring the separation efficiency.

[0062] Further, as shown in Figs. 1 and 2, the second partition plate 30 is arranged on the second cavity 112, and the second partition plate 30 is arranged in the flow channel 1111. Figure 5 and Figure 6 Further, as shown in Figs. 1 and 2, the second partition plate 30 is arranged on the second cavity 112, and the second partition plate 30 is arranged in the flow channel 1111.

[0063] It should be noted that the plurality of baffle plates 40 can correspond to the plurality of separation holes 32 one by one, and the plurality of baffle plates 40 can also correspond to a part of the plurality of separation holes 32, which can be selected according to actual application, and is not limited specifically herein.

[0064] As shown in Figs. 1 and 2, the first partition plate 20 is arranged in the flow channel 1111, and the first partition plate 20 is arranged in the flow channel 1111. Figures 1-3 As shown in Figs. 1 and 2, the first partition plate 20 is arranged in the flow channel 1111, and the first partition plate 20 is arranged in the flow channel 1111.

[0065] Specifically, the shell 10, the first partition plate 20 and the second partition plate 30 jointly define the through hole 31, and the first cavity 111 and the second cavity 112 are communicated through the through hole 31, and the separated refrigerant can flow to the through hole 31.

[0066] By setting the flow-through hole 22 and the plurality of second flow equalization holes 21 on the side of the first partition plate 20 facing the through hole 31, the refrigerant flowing to the second partition plate 30 can have a part with a lighter density flow into the second space 120 through the plurality of flow equalization holes, and a part with a heavier density flow down through the through hole 31 and then selectively flow into the second space 120 through the plurality of second flow equalization holes 21 or the flow-through hole 22, so that the separated refrigerant can be sent into the compressor.

[0067] When the refrigerant flows through the plurality of second flow equalization holes 21, the plurality of second flow equalization holes 21 can not only perform a second gas-liquid separation on the refrigerant, but also improve the uniformity and stability of the gas flow. By spacing the flow-through hole 22 below the plurality of second flow equalization holes 21 and making the flow-through hole 22 rectangular, the flow-through hole 22 can have a larger flow-through area to accommodate the flow of liquid refrigerant between the second space 120 and the second cavity 112.

[0068] In combination Figures 1-6 As shown, the second space 120 is further provided with a pipe member 60 extending in the up-down direction, and the lower end of the pipe member 60 is connected with an oil return member 63. The pipe member 60 can include a first pipe 61 and a second pipe 62 connected in the radial direction, the lower ends of the first pipe 61 and the second pipe 62 are communicated and at least partially spaced apart from the oil return member 63, the upper end of the first pipe 61 is adapted to be connected with the inlet of the compressor, and the upper end of the second pipe 62 is spaced apart from the housing 10 and communicated with the second space 120.

[0069] Specifically, the refrigerant further contains lubricating oil, which is compatible with the liquid refrigerant and can be used to lubricate the moving parts in the compressor. The lubricating oil will also be separated from the gaseous refrigerant under the action of the baffle 40.

[0070] By setting the pipe member 60 and the oil return member 63, the liquid refrigerant and the lubricating oil can enter the lower ends of the first pipe 61 and the second pipe 62 through the oil return holes 631 of the oil return member 63. After entering the second space 120, the gaseous refrigerant can flow upward through the upper end of the second pipe 62 into the second pipe 62, then flow downward along the second pipe 62 to the lower end of the second pipe 62, and then flow to the lower end of the first pipe 61, and then flow from the lower end of the first pipe 61 to the upper end of the first pipe 61, and then be communicated with the inlet of the compressor, thereby realizing the communication with the inlet of the compressor.

[0071] When the gaseous refrigerant flows at the lower end of the second pipe 62 and the lower end of the first pipe 61, it can carry away a part of the lubricating oil into the compressor, thereby ensuring the lubrication of the moving parts in the compressor, reducing friction and wear, and prolonging the service life of the equipment.

[0072] In combinationFigure 3 and Figure 4 As shown in FIG. 6, the second partition plate 30 is provided with a plurality of third partition plates 50 on the side surface facing the second cavity 112. The third partition plates 50 extend in the up-down direction and are connected to the lower side of the shell 10. The two ends of the third partition plates 50 in the radial direction are connected to the first partition plate 20 and the circumferential inner wall of the shell 10, respectively. The plurality of third partition plates 50 are arranged radially and separate the second cavity 112 into a plurality of containing cavities 1121. The plurality of containing cavities 1121 are arranged in communication with each other.

[0073] Specifically, when the high-temperature gaseous refrigerant flows into the second space 120, the liquid refrigerant in the second space 120 and the second cavity 112 will both boil due to the communication between the second cavity 112 and the second space 120. By arranging the plurality of third partition plates 50, the third partition plates 50 separate the second cavity 112 into a plurality of containing cavities 1121, and the plurality of containing cavities 1121 are arranged in communication with each other. In this way, under the premise of ensuring the liquid level balance, the liquid refrigerant in the second cavity 112 can be prevented from boiling together, ensuring the stability of the liquid refrigerant and improving the working efficiency of the gas-liquid separator 100.

[0074] In addition, the arrangement of the plurality of third partition plates 50 can also strengthen the structure of the shell 10 and improve the structural reliability of the shell 10 and even the gas-liquid separator 100.

[0075] Optionally, at least one balance hole 51 can be arranged at the position of the third partition plate 50 adjacent to the shell 10. The liquid refrigerant can flow between the adjacent two containing cavities 1121 through the balance hole 51. In addition, at least one balance hole 51 can also be arranged at the position of the lower end of the first partition plate 20 adjacent to the shell 10. In this way, the containing cavities 1121 and the second space 120 can also be communicated. In this way, the balance of the liquid level of the liquid refrigerant can be achieved.

[0076] In combination with Figures 1-3 As shown in FIG. 6, the outer periphery of the shell 10 is further provided with a bracket 15, which can be used for connection with the vehicle body. A suspension bushing 16 is arranged on the bracket 15, and the suspension bushing 16 includes a damping pad 161 and a cylinder sleeve 162. The damping pad 161 is located between the cylinder sleeve 162 and the bracket 15. By making the fastener pass through the cylinder sleeve 162 and fasten with the vehicle body, the connection between the gas-liquid separator 100 and the vehicle body can be achieved.

[0077] When the compressor vibration is transmitted to the gas-liquid separator 100, the vibration can be first decomposed and absorbed by the damping pad 161, and the residual part is attenuated by the cylinder sleeve 162 and then transmitted to the vehicle body structure. And it can be understood that when the vibration of the road surface is transmitted to the gas-liquid separator 100 through the vehicle body, the vibration attenuation transmission path is reversed. In this way, by providing the suspension bushing 16, the damping performance of the gas-liquid separator 100 and even the vehicle can be improved. Among them, the damping pad 161 can be provided with a hollow hole, so as to further improve the damping effect.

[0078] The vehicle of the utility model can mainly include: the above-mentioned gas-liquid separator 100. Specifically, by applying the gas-liquid separator 100 to the vehicle, the working performance of the vehicle can be improved, the NVH performance of the vehicle can be improved, and the product competitiveness of the vehicle can be improved, and the use experience of the user can be improved on the premise of ensuring the temperature regulation of the passenger compartment of the vehicle and ensuring the comfort of the passenger.
