Description

Technical Field

[0001] This application belongs to the field of gas-liquid separation technology, specifically, it relates to a gas-liquid separator and integrated components. Background Technology

[0002] A gas-liquid separator is a device that separates gas and liquid two-phase media. It is widely used in thermal management systems. In automotive thermal management integrated systems, gas-liquid separators are generally installed between the evaporator outlet and the compressor intake. The gas-liquid separator in the relevant technology includes a shell and a partition. The shell has a first chamber and a second chamber located on both sides of the partition. The first chamber and the second chamber are connected by a channel located on the partition. The channel has an inlet end. The gas and liquid two-phase fluid can enter the first chamber from the inlet of the gas-liquid separator and enter the second chamber through the inlet end of the channel. The partition includes a turbulence section located at the inlet end. However, only a portion of the gas and liquid two-phase fluid in the first chamber can be separated by the action of the partition and the turbulence section. That is, the fluid flow rate acting on the partition and the turbulence section is relatively small. Summary of the Invention

[0003] The applicant has discovered through extensive research that the fluid flow rate acting on the turbulence section is related to the fluid velocity, and that the fluid velocity at the outlet of the first channel is greater than the fluid velocity at the inlet of the first channel. This application provides a gas-liquid separator designed to increase the fluid flow rate acting on the turbulence section.

[0004] To achieve the above objectives, this application provides a gas-liquid separator, including a housing and a first baffle. The first baffle is located in the housing cavity, which includes a first cavity and a second cavity. The housing has an inlet, and the second cavity is located on the side of the first cavity away from the inlet. The first baffle has a first channel that connects the first cavity and the second cavity.

[0005] The first channel has an outlet end located at one end of the first channel near the second cavity, and the first baffle includes a turbulence portion, at least a portion of which is located on the side of the first baffle having the outlet end.

[0006] The gas-liquid separator provided in this application includes a housing and a first baffle. The first baffle is located in the housing cavity, which includes a first cavity and a second cavity. The first baffle has a first channel connecting the first cavity and the second cavity. Fluid in the gas-liquid separator can enter the second cavity from the first cavity through the first channel. The first channel has an outlet end. The first baffle includes a turbulence portion, at least part of which is located on the side of the first baffle with the outlet end. The fluid velocity flowing out of the first cavity through the outlet end of the first channel is increased, making it easier for the fluid from the outlet end of the first channel to be sprayed into the turbulence portion located at the outlet end in a jet-like flow state. Therefore, the fluid flow rate acting on the turbulence portion can be increased. Attached Figure Description

[0024] A gas-liquid separator according to this application includes a housing C0 and a first baffle C1. The first baffle C1 is connected to the housing C0 and is located in the cavity C00 of the housing C0. The cavity C00 includes a first cavity C01 and a second cavity C02. The housing C0 has an inlet C08. The second cavity C02 is located on the side of the first cavity C01 away from the inlet C08. The first baffle C1 has a first channel C10 that connects the first cavity C01 and the second cavity C02.

[0025] The first channel C10 has an outlet end C10a, which is located at one end of the first channel C10 near the second cavity C02. The first baffle C1 includes a turbulence portion C13, at least a portion of which is located on the side of the first baffle C1 with the outlet end C10a.

[0026] The gas-liquid separator provided in this application includes a housing C0 and a first baffle C1. The first baffle C1 is located in the cavity C00 of the housing C0. The cavity C00 includes a first cavity C01 and a second cavity C02. The first baffle C1 has a first channel C10 connecting the first cavity C01 and the second cavity C02. Fluid in the gas-liquid separator can enter the second cavity C02 from the first cavity C01 through the first channel C10. The first channel C10 has an outlet end C10a. The first baffle C1 includes a turbulence portion C13. At least part of the turbulence portion C13 is located on the side of the first baffle C1 with the outlet end C10a. The flow velocity of the fluid flowing out of the first cavity C01 through the outlet end C10a of the first channel C10 increases. The fluid from the outlet end C10a of the first channel C10 is more easily sprayed into the turbulence portion C13 located at the outlet end C10a in a jet-like flow state. Therefore, the gas-liquid separator of this application can increase the fluid flow rate acting on the turbulence portion C13.

[0027] According to a specific embodiment of this application, please refer to Figures 1 to 11 The gas-liquid separator includes a housing C0 and a first baffle C1, which are connected. The housing C0 has a cavity C00, and the first baffle C1 is located in the cavity C00.

[0028] The shell C0 has an inlet C08, through which fluid can enter the shell cavity C00.

[0029] The cavity C00 includes a first cavity C01 and a second cavity C02. The second cavity C02 is located on the side of the first cavity C01 away from the inlet C08. The first cavity C01 and the second cavity C02 are located on both sides of the first baffle C1, and the first baffle C1 isolates the first cavity C01 and the second cavity C02. Fluid can enter the first cavity C01 from the inlet C08.

[0030] In this embodiment, the first baffle C1 has a first channel C10, which connects the first cavity C01 and the second cavity C02. Fluid can enter the first cavity C01 from the inlet C08, and fluid located in the first cavity C01 can enter the second cavity C02 from the first channel C10.

[0031] The housing C0 and the first baffle C1 are assembled or are a single piece.

[0032] Optionally, the assembly connection of the housing C0 and the first baffle C1 includes, but is not limited to, one or more of the following: screw connection, bolt connection, adhesive bonding, and snap-fit ​​connection.

[0033] This embodiment describes the connection between the housing C0 and the first baffle C1 via a snap-fit ​​method. Figure 1 and Figure 2 As shown, the housing C0 is designed with a slot, and part of the first baffle C1 or the connecting part of the first baffle C1 is located in the slot.

[0034] In this embodiment, the first channel C10 has an outlet end C10a, which is located at the end of the first channel C10 near the second cavity C02, or at the end of the first channel C10 away from the first cavity C01; the first channel C10 also has an inlet end C10b, which is located at the end of the first channel C10 away from the second cavity C02, or at the end of the first channel C10 near the first cavity C01. Fluid in the first cavity C01 can enter the first channel C10 from the inlet end C10b, and fluid can flow out of the first channel C10 from the outlet end C10a and enter the second cavity C02, as shown below. Figure 7 As shown.

[0035] The applicant discovered through extensive research that the fluid flow rate acting on the turbulence section C13 is related to the fluid velocity, and the fluid velocity at the outlet end C10a of the first channel C10 is greater than the fluid velocity at the inlet end C10b. Therefore, by adjusting the position of the turbulence section C13 to a position with a high fluid velocity, the fluid flow rate acting on the turbulence section C13 can be increased.

[0036] The first baffle C1 includes a flow-dispersing section C13. While gas-liquid separators in the prior art incorporate a flow-dispersing section C13, this section is located at the inlet end C10b of the first channel C10. In this embodiment, at least a portion of the flow-dispersing section C13 is located on the side of the first baffle C1 with the outlet end C10a. The fluid velocity flowing out of the first cavity C01 through the outlet end C10a of the first channel C10 increases. Based on this finding, the fluid from the outlet end C10a of the first channel C10 is more easily jetted into the flow-dispersing section C13 located at the outlet end C10a. Therefore, the gas-liquid separator of this embodiment can increase the fluid flow rate acting on the flow-dispersing section C13.

[0037] Since this embodiment can act on the fluid flow rate of the turbulence section C13, the turbulence section C13 can perform gas-liquid separation on a larger flow rate of fluid. The gas-liquid separation effect of the turbulence section C13 in this embodiment is better, and ultimately, the gas-liquid separation effect of the entire gas-liquid separator can be improved.

[0038] In this embodiment, the turbulence section C13 includes a first turbulence section C131, which is located on the side of the first baffle C1 with an outlet end C10a. The fluid velocity at the outlet end C10a is higher than that at the inlet end C10b. The first turbulence section C131 located at the outlet end C10a can make it easier for the fluid from the outlet end C10a of the first channel C10 to be ejected in a jet-like flow state. Therefore, the fluid flow rate acting on the first turbulence section C131 is larger, and the gas-liquid separation effect of the first turbulence section C131 is better.

[0039] The first turbulence section C131 is located in the second cavity C02.

[0040] The first baffle C1 includes a first plate portion C14, which is connected to a first flow-deflecting portion C131. The first plate portion C14 and the first flow-deflecting portion C131 extend along the length direction X of the housing C0, as shown below. Figure 2 As shown.

[0041] The first plate C14 and the first spoiler C131 are assembled or are integrated as a single unit.

[0042] Optionally, the assembly connection between the first plate portion C14 and the first spoiler portion C131 includes, but is not limited to, one or more of the following: screw connection, bolt connection, adhesive bonding, and snap-fit ​​connection.

[0043] This embodiment takes the first plate part C14 and the first turbulence part C131 as an integral part as an example. The first plate part C14 and the first turbulence part C131 in this embodiment can be integrally extruded and the processing technology is simple and convenient.

[0044] The first channel C10 is located at the first plate section C14, such as Figure 2 and Figure 5As shown.

[0045] In this embodiment, the turbulence section C13 includes a second turbulence section C132, which is located on the side of the first baffle C1 with the inlet end C10b, and is connected to the first plate section C14.

[0046] The second turbulence section C132 is located in the first cavity C01.

[0047] The gas-liquid two-phase fluid located in the first chamber C01 can act on the second turbulence section C132 to achieve initial gas-liquid separation. Then, it enters the second chamber C02 through the first channel C10 and achieves secondary gas-liquid separation under the action of the first turbulence section C131. The combination of the first turbulence section C131 and the second turbulence section C132 can increase the area of ​​the fluid acting on the turbulence section C13, thereby improving the gas-liquid separation effect of the turbulence section C13 and thus improving the overall gas-liquid separation effect of the gas-liquid separator.

[0048] The first plate C14 and the second spoiler C132 are assembled or are integrated as a single unit.

[0049] Optionally, the assembly connection between the first plate portion C14 and the second spoiler portion C132 includes, but is not limited to, one or more of the following: screw connection, bolt connection, adhesive bonding, and snap-fit ​​connection.

[0050] This embodiment takes the first plate part C14 and the second turbulence part C132 as an integral part as an example. The first plate part C14 and the second turbulence part C132 in this embodiment can be integrally extruded and the processing technology is simple and convenient.

[0051] In this embodiment, the first plate portion C14 includes a first ear portion C15, which protrudes from the side of the first cavity C01 pointing towards the second cavity C02, as shown below. Figure 5 As shown.

[0052] The fluid can act on the first ear portion C15, the second turbulence portion C132, and the first turbulence portion C131 in sequence. In other words, the fluid can hit the surfaces of the first ear portion C15, the second turbulence portion C132, and the first turbulence portion C131 in sequence. That is, the fluid can come into contact with the surfaces of the first ear portion C15, the second turbulence portion C132, and the first turbulence portion C131 in sequence. The first ear portion C15, the second turbulence portion C132, and the first turbulence portion C131 all have the effect of separating the gaseous and liquid states of the fluid. That is, the first ear portion C15, the second turbulence portion C132, and the first turbulence portion C131 all have a gas-liquid separation function.

[0053] The fluid entering the first chamber C01 from the inlet C08 can hit the wall of the first ear C15 to achieve gas-liquid separation. The separated gaseous fluid can flow along the wall contour of the first ear C15 to the second turbulence section C132. The first ear C15 is conducive to the formation of fluid vortices along its wall contour, so as to improve the gas-liquid separation effect of the fluid in the first ear C15.

[0054] Furthermore, the first ear portion C15 includes a first ear wall C151 and a second ear wall C152, which are arranged along the thickness direction of the first baffle C1. The first ear wall C151 is closer to the inlet C08 than the second ear wall C152. Figure 9 As shown;

[0055] The first flow-disrupting section C131 includes a first flow-disrupting wall C1311 and a second flow-disrupting wall C1312. The first flow-disrupting wall C1311 is closer to the outlet end C10a than the second flow-disrupting wall C1312. Figure 9 As shown;

[0056] The plane perpendicular to the length direction of the shell C0 is defined as the second reference plane. The projection of the first ear wall C151 onto the second reference plane is the first arc, and the projection of the first spoiler wall C1311 onto the second reference plane is the second arc. The arc length of the first arc is greater than the arc length of the second arc.

[0057] In this embodiment, the arc length of the first arc obtained by orthographic projection of the first ear wall C151 is longer than the arc length of the second arc obtained by orthographic projection of the first turbulence wall C1311. In other words, the curvature of the first ear C15 is larger than the curvature of the first turbulence section C131. Under the guidance and turbulence effect of the first ear wall C151, a vortex is formed in the first turbulence section C131, which makes the fluid entering the first cavity C01 from the inlet C08 tend to gather towards the first ear C15, thereby promoting more fluid to flow towards the first baffle C1, increasing the flow rate of fluid to the first baffle C1, and thus improving the gas-liquid separation effect of the first ear C15, the second turbulence section C132, and the first turbulence section C131.

[0058] In this embodiment, the first channel C10 penetrates the side of the first baffle C1 along its thickness direction. The first baffle C1 includes a first wall C11 and a second wall C12 disposed along its thickness direction. Compared to the first wall C11, the second wall C12 is further away from the inlet C08. Figure 5 As shown;

[0059] The first channel C10 has the following characteristics: Figure 6 The first port C101 shown is the outlet of the first channel C10, and fluid can flow out of the first channel C10 from the first port C101.

[0060] The first opening C101 is located on the second wall C12. The plane where the second wall C12 is located is defined as the first reference plane. The first turbulence part C131 is projected onto the first reference plane. The projection surface of the first turbulence part C131 on the first reference plane is S1, and the projection surface of the first opening C101 on the first reference plane is S2. S1 and S2 at least partially overlap.

[0061] In this embodiment, S1 and S2 at least partially overlap. In other words, along the thickness direction of the first baffle C1, the first turbulence part C131 at least partially blocks part of the first opening C101. This design allows more fluid flowing out of the first opening C101 to hit the surface of the first turbulence part C131, thereby improving the gas-liquid separation effect of the gas-liquid separator.

[0062] In this embodiment, the gas-liquid separator includes a second baffle C2 located in the cavity C00 of the housing C0. The cavity C00 includes a third cavity C03 located on the side of the second cavity C02 away from the first cavity C01. The second baffle C2 has a second channel C20 connecting the second cavity C02 and the third cavity C03. Figure 5 and Figure 7 As shown; the fluid in the second chamber CO2 can enter the third chamber CO3 through the second channel C20.

[0063] The second baffle C2 includes a rectifier C23, and at least part of the rectifier C23 has a third cavity C03; the rectifier C23 can guide and turbulent the fluid.

[0064] Furthermore, the rectifier C23 includes a first rectifier C231, which is located in the third cavity C03. The first rectifier C231 can guide and turbulent at least a portion of the fluid entering the third cavity C03 from the second channel C20, so as to further improve the gas-liquid separation effect.

[0065] Similarly, the second channel C20 penetrates the side of the second baffle C2 along its thickness direction. The second baffle C2 includes a third wall C21 and a fourth wall C22 arranged along its thickness direction. Compared to the fourth wall C22, the third wall C21 is closer to the inlet C08. Figure 5 As shown;

[0066] like Figure 9 As shown, the second channel C20 has a second port C201, which is the outlet of the second channel C20, and fluid can flow out of the second channel C20 from the second port C201.

[0067] Combination Figure 5 and Figure 9It can be seen that the second port C201 is located on the fourth wall C22. The plane where the fourth wall C22 is located is defined as the third reference plane. The first rectifier C231 is projected onto the third reference plane. The projection plane of the first rectifier C231 on the third reference plane is S3, and the projection plane of the second port C201 on the third reference plane is S4. S3 and S4 at least partially overlap.

[0068] In this embodiment, S3 and S4 at least partially overlap. In other words, along the thickness direction of the second baffle C2, the first rectifier C231 at least partially blocks part of the second port C201. This design allows more fluid flowing out of the second port C201 to hit the surface of the first rectifier C231, thereby improving the gas-liquid separation effect of the gas-liquid separator.

[0069] Optionally, the thickness direction of the second baffle C2 is consistent with the thickness direction of the first baffle C1, and the third reference plane is parallel to or coincides with the first reference plane.

[0070] In this embodiment, the second baffle C2 includes a second plate portion C24, which is connected to the first rectifier portion C231. The second plate portion C24 and the first rectifier portion C231 extend along the length direction X of the housing C0, as shown below. Figure 2 As shown.

[0071] The second plate C24 is assembled and connected to the first rectifier C231 or is a single unit.

[0072] Optionally, the assembly connection between the second plate C24 and the first rectifier C231 includes, but is not limited to, one or more of the following: screw connection, bolt connection, adhesive bonding, and snap-fit ​​connection.

[0073] This embodiment takes the second plate C24 and the first rectifier C231 as an integral part as an example. The second plate C24 and the first rectifier C231 in this embodiment can be integrally extruded and the processing technology is simple and convenient.

[0074] The second channel C20 is located at the second plate section C24, such as Figure 5 and Figure 6 As shown;

[0075] In this embodiment, the rectifier C23 includes a second rectifier C232, which is located at the end of the second channel C20 away from the second port C201, that is, the second rectifier C232 is located at the entrance end of the second channel C20, and the second rectifier C232 is connected to the second plate C24.

[0076] The second rectifier section C232 is located in the second cavity C02.

[0077] The gas-liquid two-phase fluid located in the first chamber C01 can act on the second turbulence section C132 to achieve initial gas-liquid separation. Then, it enters the second chamber C02 through the first channel C10 and achieves secondary gas-liquid separation under the action of the first turbulence section C131. Next, the fluid that has completed the secondary gas-liquid separation can act on the second rectifier section C232 to achieve a third gas-liquid separation. Then, it enters the third chamber C03 through the second channel C20 and completes a fourth gas-liquid separation under the action of the first rectifier section C231. The combination of the first rectifier section C231 and the second rectifier section C232 can increase the area of ​​the fluid acting on the rectifier section C23, thereby improving the gas-liquid separation effect of the turbulence section C23 and thus improving the overall gas-liquid separation effect of the gas-liquid separator.

[0078] In summary, the combination of the first turbulence section C131 and the second turbulence section C132 in this embodiment, combined with the combined effect of the first rectifier section C231 and the second rectifier section C232, allows the fluid to undergo two gas-liquid separation processes in the second cavity CO2, resulting in a better gas-liquid separation effect.

[0079] Optionally, the second plate C24 and the second rectifier C232 can be assembled and connected together or be a single unit.

[0080] Optionally, the assembly connection between the second plate C24 and the second rectifier C232 includes, but is not limited to, one or more of the following: screw connection, bolt connection, adhesive bonding, and snap-fit ​​connection.

[0081] This embodiment takes the second plate C24 and the second rectifier C232 as an integral part as an example. The second plate C24 and the second rectifier C232 in this embodiment can be integrally extruded and the processing technology is simple and convenient.

[0082] The second plate portion C24 includes a second ear portion C25, which is connected to the second plate portion C24. The second ear portion C25 protrudes from the side pointing from the second cavity C02 towards the third cavity C03, as shown below. Figure 5 and Figure 10 As shown;

[0083] The rectifier C23 includes a second rectifier C232, which is located in the second cavity C02 and extends from the second baffle C2 toward the side closer to the first baffle C01.

[0084] The fluid entering the second cavity C02 from the first channel C10 can hit the wall of the second ear C25 to achieve gas-liquid separation. The separated gaseous fluid can flow along the wall contour of the second ear C25 to the second rectifier C232. The second ear C25 is conducive to the formation of fluid vortices along its wall contour, so as to improve the gas-liquid separation effect of the fluid in the second ear C25.

[0085] The fluid entering the second cavity C02 from the first channel C10 can act on the second ear C25, the second rectifier C232, and the first rectifier C231 in sequence. In other words, the fluid can hit the surfaces of the second ear C25, the second rectifier C232, and the first rectifier C231 in sequence. That is, the fluid can come into contact with the surfaces of the second ear C25, the second rectifier C232, and the first rectifier C231 in sequence. The second ear C25, the second rectifier C232, and the first rectifier C231 all have the effect of separating the gaseous and liquid states of the fluid. That is, the second ear C25, the second rectifier C232, and the first rectifier C231 all have a gas-liquid separation function.

[0086] Furthermore, the second ear portion C25 includes a third ear wall C251 and a fourth ear wall C252, which are arranged along the thickness direction of the second baffle C2. The third ear wall C251 is closer to the inlet C08 than the fourth ear wall C252. Figure 5 and Figure 10 As shown;

[0087] The first rectifier section C231 includes a first rectifier wall C2311 and a second rectifier wall C2312. The first rectifier wall C2311 is closer to the second inlet C201 than the second rectifier wall C2312. Figure 10 As shown;

[0088] The plane perpendicular to the length direction of the shell C0 is defined as the second reference plane. The projection of the third ear wall C251 onto the second reference plane is the third arc. The projection of the first rectifying wall C2311 onto the second reference plane is the fourth arc. The arc length of the third arc is greater than the arc length of the fourth arc.

[0089] In this embodiment, the arc length of the third arc obtained by orthographic projection of the third ear wall C251 is longer than the arc length of the fourth arc obtained by orthographic projection of the first rectifying wall C2311. In other words, the curvature of the second ear C25 is larger than the curvature of the first rectifying part C231. Under the guidance and turbulence effect of the third ear wall C251, a vortex is formed in the first rectifying part C231, which makes the fluid entering the second cavity C02 from the first channel C10 tend to gather towards the second ear C25, thereby improving the gas-liquid separation effect of the second ear C25, the second rectifying part C232 and the first rectifying part C231.

[0090] like Figure 7 As shown, the Y direction is defined as the width direction of the shell C0. If the fluid in the first chamber C01 can flow from Y+ to Y-, then the fluid in the second chamber C02 can move from Y- to Y+. That is, the fluid in the gas-liquid separator can move along the Y- direction. Figure 7 The flow path shown is long, resulting in good gas-liquid separation during the flow process.

[0091] In this embodiment, the gas-liquid separator includes a shelf C3, which has a through hole C30 that penetrates the end faces of both ends of the shelf C3 along its thickness direction. Figure 5 and Figure 6 As shown;

[0092] The shell cavity C00 includes a fourth cavity C04, a through hole C30 connecting the first cavity C01 and the fourth cavity C04, a through hole C30 connecting the second cavity C02 and the fourth cavity C04, and a through hole C30 connecting the third cavity C03 and the fourth cavity C04.

[0093] The first cavity C01 and the fourth cavity C04 are arranged along the X direction, the second cavity C02 and the fourth cavity C04 are arranged along the X direction, and the third cavity C03 and the fourth cavity C04 are arranged along the X direction.

[0094] The liquid phase fluid that has completed gas-liquid separation in the first chamber C01 can flow into the fourth chamber C04 through the through hole C30. The liquid phase fluid that has completed gas-liquid separation in the second chamber C02 can flow into the fourth chamber C04 through the through hole C30. The liquid phase fluid that has completed gas-liquid separation in the third chamber C03 can flow into the fourth chamber C04 through the through hole C30.

[0095] The through hole C30 includes a first through hole C301 and a second through hole C302. At least a portion of the first through hole C301 is located between the first ear portion C15 and the second turbulence portion C132, and at least a portion of the second through hole C302 is located between the first turbulence portion C131 and the first plate portion C14. Figure 9 As shown, the first through hole C301 and the second through hole C302 extend discontinuously. In other words, the first through hole C301 and the second through hole C302 are two independent holes, which makes the layer plate C3 have high strength and long service life in the part with the first through hole C301 and the second through hole C302.

[0096] Optionally, the through hole C30 includes a third through hole C303 and a fourth through hole C304, with at least a portion of the third through hole C303 located between the second ear portion C25 and the second rectifier portion C232, and at least a portion of the fourth through hole C304 located between the first rectifier portion C231 and the second plate portion C24, as shown. Figure 10 As shown, the third through hole C303 and the fourth through hole C304 extend discontinuously. In other words, the third through hole C303 and the fourth through hole C304 are two independent holes, which makes the layer C3 have high strength and long service life in the part with the third through hole C303 and the fourth through hole C304.

[0097] In this application, the gas-liquid separator includes a partition C4, at least a portion of which is connected to the housing C0, and at least a portion of which is connected to the shelf C3, as shown below. Figure 1 As shown;

[0098] The partition C4 and the housing C0 are assembled or are integral parts. Optionally, the assembly connection between the partition C4 and the housing C0 includes, but is not limited to, one or more of the following: screw connection, bolt connection, adhesive bonding, and snap-fit ​​connection.

[0099] This embodiment takes the partition C4 and the shelf C3 as an integral part as an example. The partition C4 and the shelf C3 in this embodiment can be integrally extruded and the processing technology is simple and convenient.

[0100] Similarly, the partition C4 and the shelf C3 are assembled or are integrated as a single unit.

[0101] Cavity C00 includes a fifth cavity C05, a sixth cavity C06, and a seventh cavity C07. The fifth cavity C05 is located on the side of the sixth cavity C06 furthest from the seventh cavity C07. Please refer to [reference needed]. Figure 3 , Figure 4 and Figure 5 As shown.

[0102] The partition C4 has a first groove C41, which connects the fifth cavity C05 and the fourth cavity C04, as follows: Figure 4 and Figure 8 As shown.

[0103] The partition C4 has a second groove C42, which connects the fifth cavity C05 and the third cavity C03, as shown below. Figure 3 and Figure 4 As shown.

The first end cap C51 and the second end cap C52 are arranged along the thickness direction of the layer plate C3. In other words, the first end cap C51 and the second end cap C52 are arranged along the thickness direction of the layer plate C3. Figure 2 As shown in the X-axis orientation, the second end cap C52 is closer to the fourth cavity C04 than the first end cap C51;

[0107] The first groove C41 is located on the side of partition C4 near the second end cap C52, the second groove C42 is located on the side of partition C4 near the first end cap C51, the third groove C43 is located on the side of partition C4 near the first end cap C51, and the fourth groove C44 is located on the side of partition C4 near the second end cap C52, as shown below. Figure 3 and Figure 4 As shown.

[0108] The gas-liquid separator in this embodiment has an outlet C09, through which the fluid inside the gas-liquid separator can flow out of the gas-liquid separator. The outlet C09 penetrates the end faces of both ends of the housing C0 along the thickness direction of the housing C0.

[0109] The outlet C09 and the inlet C08 are located at the same end of the shell C0.

[0110] The gas-liquid two-phase fluid entering the gas-liquid separator from C08 first enters the first chamber C01, where gas-liquid separation is completed. The liquid phase fluid that has completed gas-liquid separation in the first chamber C01 can enter the fourth chamber C04 through the first through-hole C301. The gas phase fluid that has completed gas-liquid separation in the first chamber C01 can enter the second chamber C02 through the first channel C10, where gas-liquid separation is completed. The liquid phase fluid that has completed gas-liquid separation in the second chamber C02 can enter the fourth chamber C04 through the second through-hole C302 and the third through-hole C303. The gaseous fluid that has completed gas-liquid separation in the second chamber C02 can enter the third chamber C03 through the second channel C20, and complete gas-liquid separation in the third chamber C03. The liquid fluid that has completed gas-liquid separation in the third chamber C03 can enter the fourth chamber C04 through the fourth through hole C304. The gaseous fluid that has completed gas-liquid separation in the third chamber C03 can enter the fifth chamber C05 through the second groove C42, enter the sixth chamber C06 through the third groove C43, enter the seventh chamber C07 through the fourth groove C44, and flow out of the gas-liquid separator from the outlet C09.

[0111] Of course, the liquid fluid located in the fourth chamber C04 can enter the fifth chamber C05 from the first tank C41.

[0112] Of course, when there is a gap between the liquid surface of the fourth chamber C04 and the first tank C41, the gaseous fluid can also enter the fifth chamber C05 from the first tank C41.

[0113] The partition C4 located between the fifth chamber C05 and the sixth chamber C06 serves to isolate the liquid phase fluid.

[0114] In this embodiment, the gas-liquid separator includes a vertical plate C6, which is located between the shelf C3 and the second end cap C52. The vertical plate C6 has a third channel C60, which connects the third chamber C03 and the fourth chamber C04. Figure 4 and Figure 8 As shown.

[0115] The third channel C60 is located at the end of the vertical plate C6 near the shelf C3.

[0116] The gaseous fluid located in the third chamber C03 can enter the fourth chamber C04 through the third channel C60, and enter the fifth chamber C05 through the first groove C41.

[0117] The vertical plate C6 has a flow guide hole C61, such as Figure 3 , Figure 4 and Figure 8 As shown, the guide hole C61 penetrates the end faces of both ends of the vertical plate C6 along the thickness direction. The guide hole C61 has the function of guiding the liquid fluid located in the fourth cavity C04. In addition, the vertical plate C6 has the function of separating the liquid fluid. The vertical plate C6 is also used to position and support the layer plate C3.

[0118] The gas-liquid separator of this application can also be designed with a drying device, which can be placed in the third chamber CO3. In other words, the third chamber CO3 can store the drying device, which is located on the side of the vertical plate C6 away from the fourth chamber CO4. The drying device has a water absorption effect.

[0119] In this embodiment, the gas-liquid separator includes a liquid return device C7. The outlet C09 and inlet C08 are located at one end of the housing C0, and the liquid return device C7 is located at the other end of the housing C0. In other words, the outlet C09 and inlet C08 are located at the end of the housing C0 near the first end cover C51, and the liquid return device C7 is located at the end of the housing C0 near the second end cover C52. Figure 2 and Figure 8 As shown.

[0120] The return liquid device C7 connects the fourth chamber C04 and the seventh chamber C07. The housing C0 has a first return liquid channel C71, which connects the return liquid device C7 and the seventh chamber C07. The first return liquid channel C71 is located on the side of the housing C0 near the second end cap C52.

[0121] The housing C0 has a second return channel C72, which connects the return device C7 and the fourth chamber C04. The second return channel C72 is located on the side of the housing C0 near the second end cap C52.

[0122] The liquid fluid located in the fourth chamber C04 can enter the return device C7 through the second return channel C72, and enter the seventh chamber C07 through the first return channel C71.

[0123] When the gas-liquid separator of this embodiment is used in conjunction with the compression mechanism, the outlet C09 of the gas-liquid separator is usually connected to the intake port of the compression mechanism. When the gas-liquid separator is used in conjunction with the compression mechanism, the aforementioned return liquid device C7 can be used for oil return. That is, part of the liquid phase fluid entering the seventh chamber C07 through the first return liquid channel C71 can flow with the gas phase fluid in the seventh chamber C07. In other words, the gas phase fluid in the seventh chamber C07 can carry away part of the liquid phase fluid entering the seventh chamber C07. Since the liquid phase fluid is usually mixed with oil, it is possible to achieve the effect of the gas phase fluid carrying part of the oil back to the intake port of the compression mechanism.

[0124] Optionally, in this embodiment, please refer to Figure 4 As shown, along the thickness direction of the plate C3, the maximum distance between the fourth groove C44 and the second end cap C52 is defined as L1, and the maximum distance between the first return channel C71 and the second end cap C52 is defined as L2, where L1 > L2.

[0125] By designing L1 > L2, the probability of liquid fluid affecting gaseous fluid flow through the fourth groove C44 can be reduced, and the probability of gaseous fluid entering the seventh chamber C07 through the fourth groove C44 can be increased.

[0126] This application also provides an integrated component, which includes a gas-liquid separator C and a flow channel 1. The flow channel 1 has a flow channel, and the gas-liquid separator C includes an inlet C08ˊ and an exhaust port C09ˊ. At least one of the inlet C08ˊ and the exhaust port C09ˊ is in communication with the flow channel.

[0127] The inlet C08ˊ here is equivalent to the inlet C08 mentioned above, and similarly, the exhaust port C09ˊ here is equivalent to the inlet C09 mentioned above.

[0128] The gas-liquid separator C includes a first baffle C1. The gas-liquid separator C has a first chamber C01 and a second chamber C02. The second chamber C02 is located on the side of the first chamber C01 away from the inlet C08'. The first baffle C1 has a first channel C10, which connects the first chamber C01 and the second chamber C02.

[0129] The first channel C10 has an outlet end C10a, which is located at one end of the first channel C10 near the second cavity C02. The first baffle C1 includes a turbulence portion C13, at least a portion of which is located on the side of the first baffle C1 with the outlet end C10a.

[0130] In the gas-liquid separator applied to integrated components, fluid can enter the second chamber C02 from the first chamber C01 through the first channel C10. The first channel C10 has an outlet end C10a. The first baffle C1 includes a turbulence section C13, at least part of which is located on the side of the first baffle C1 with the outlet end C10a. The fluid velocity flowing out of the first chamber C01 through the outlet end C10a of the first channel C10 increases, and the fluid from the outlet end C10a of the first channel C10 is more easily sprayed into the turbulence section C13 located at the outlet end C10a in a jet-like flow state. Therefore, the gas-liquid separator of this application can increase the fluid flow rate acting on the turbulence section C13.

[0131] The gas-liquid separator C is connected to the flow channel 1, and the integrated component of this application can be applied to a thermal management integrated device.

[0132] The integrated component includes a compression module 4 and the gas-liquid separator C of the present application. The flow channel 1 has a flow channel that can connect the gas-liquid separator C and the compression module 4. Specifically, the flow channel can connect the outlet C09 of the gas-liquid separator C and the intake port of the compression module 4.

[0133] The compression module 4 includes a cylindrical part 41, which is integral with the flow channel part 1 and can be integrally formed by extrusion.

[0134] The integrated component includes a heat exchange component, which includes a first heat exchanger A1 and a second heat exchanger A2. The first heat exchanger A1 is connected to the flow channel 1, and the second heat exchanger A2 is connected to the flow channel 1.

[0135] The integrated component also includes valve B. When the integrated component is applied to an automotive thermal management system, one of the first heat exchanger A1 and the second heat exchanger A2 is configured as a condenser, and the other is selected as an evaporator. Valve B is connected to the flow path between the first heat exchanger A1 and the second heat exchanger A2, and is located in the flow path from the condenser to the evaporator. Valve B can be integrated into and connected to the flow channel 1.

[0136] At least one valve B shall be provided.

[0137] The integrated component also includes a sensor D, at least one of which is provided, and the sensor D is connected to the flow channel 1;

[0138] like Figure 11 As shown, by integrating the first heat exchanger A1, the second heat exchanger A2, the valve B, the sensor D, the compression module 4, and the gas-liquid separator C into the flow channel section 1 and all located on the same plane of the flow channel section 1, it is beneficial for the integrated components to be laid out in a highly integrated manner.

[0139] Some of the technical implementation methods described above can be combined or replaced.

[0140] The technical principles of this application have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this application that can be conceived by those skilled in the art without creative effort will fall within the scope of protection of this application.
