[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference below Figure 1-Figure 4 The gas-liquid separation device 100 and the vehicle according to the embodiment of the utility model are described. The gas-liquid separation device 100 can be used alone, or the gas-liquid separation device 100 can also be integrated with a silencer mechanism.

[0030] like Figure 1 and Figure 4As shown, the gas-liquid separation device 100 according to the embodiment of the utility model includes: a shell 10, the shell 10 defines a gas-liquid separation space 11; a partition 20, the partition 20 is arranged in the gas-liquid separation space 11 to separate the gas-liquid separation space 11 into a first gas-liquid separation space 111 and a second gas-liquid separation space 112, the upper half of the partition 20 is formed with a first through hole 21, the first through hole 21 connects the first gas-liquid separation space 111 and the second gas-liquid separation space 112, and the shell 10 is formed with An air outlet 12 connected to the second gas-liquid separation space 112; an air inlet pipe 30, at least a portion of which is assembled in the first gas-liquid separation space 111, the air inlet pipe 30 defines an air inlet groove 31 with one end open, the open end of the air inlet groove 31 is configured as an air inlet 32, and a side wall of the air inlet groove 31 is formed with a second through hole 33 located in the first gas-liquid separation space 111, the second through hole 33 connects the first gas-liquid separation space 111 and the air inlet groove 31, and the second through hole 33 is formed in the lower half of the air inlet pipe 30.

[0031] Among them, the shell 10 can define a gas-liquid separation space 11, and the temperature inside the shell 10 is different from the temperature outside the shell 10. Due to the continuous heat exchange between the inside and the outside of the shell 10, the temperature in the gas-liquid separation space 11 can be lower than the exhaust temperature, so that the moisture in the gas can be precipitated, thereby achieving the effect of gas-liquid separation.

[0032] The shape of the separator 20 can be adapted to the housing 10, and the separator 20 can be arranged in the gas-liquid separation space 11 so that the separator 20 can separate the gas-liquid separation space 11 into a first gas-liquid separation space 111 and a second gas-liquid separation space 112. It can be explained that the volumes of the first gas-liquid separation space 111 and the second gas-liquid separation space 112 can be the same or different, and are not specifically limited here, and can be reasonably set according to actual conditions. The upper half of the separator 20 can be formed with a first through hole 21, and the first through hole 21 can penetrate the separator 20 along the thickness direction of the separator 20, so that the first through hole 21 connects the first gas-liquid separation space 111 and the second gas-liquid separation space 112, so that the gas-liquid mixture entering the first gas-liquid separation space 111 can enter the second gas-liquid separation space 112 through the first through hole 21. During this process, part of the gas-liquid mixture will be separated into gas-liquid. Since the first through hole 21 is formed only in the upper half of the partition 20, the gas in the first gas-liquid separation space 111 can only move upward and enter the second gas-liquid separation space 112 through the first through hole 21 in the upper half of the partition 20. The liquid separated in the first gas-liquid separation space 111 moves downward, which can reduce the risk of the liquid being carried away by the airflow when moving downward, thereby improving the gas-liquid separation effect of the gas-liquid separation device 100.

[0033] As an example of the present invention, there may be multiple first through holes 21 , and multiple first through holes 21 can increase the speed at which the gas-liquid mixture enters the second gas-liquid separation space 112 , thereby improving the gas-liquid separation efficiency of the gas-liquid separation device 100 .

[0034] The shell 10 can be formed with an outlet 12 connected to the second gas-liquid separation space 112, so that the separated gas in the gas-liquid separation space 11 can flow out of the shell 10 from the first gas-liquid separation space 111, the second gas-liquid separation space 112, and the outlet 12 in sequence. In addition, the first gas-liquid separation space 111 and the second gas-liquid separation space 112 can perform multiple gas-liquid separations, thereby improving the gas-liquid separation effect.

[0035] At least part of the air intake pipe 30 is assembled in the first gas-liquid separation space 111, for example: one half of the air intake pipe 30 can be assembled in the first gas-liquid separation space 111, or one third of the air intake pipe 30 can be assembled in the first gas-liquid separation space 111, but the utility model is not limited thereto, and the air intake pipe 30 can also be fully assembled in the first gas-liquid separation space 111, as long as at least part of the air intake pipe 30 is assembled in the first gas-liquid separation space 111. The air intake pipe 30 defines an air intake groove 31 with one end open, and the open end of the air intake groove 31 is configured as an air intake port 32, which can be connected to the cathode pipe of the fuel cell to receive the exhaust generated by the cathode side of the fuel cell, and the exhaust is a large amount of gas-liquid mixture.

[0036] The side wall of the air inlet groove 31 may be formed with a second through hole 33 located in the first gas-liquid separation space 111. The second through hole 33 may penetrate the side wall of the air inlet groove 31 along the thickness direction of the side wall of the air inlet groove 31, so that the second through hole 33 connects the first gas-liquid separation space 111 and the air inlet groove 31, and enables the gas-liquid mixture to enter the first gas-liquid separation space 111 from the air inlet port 32 for gas-liquid separation, thereby reducing the moisture in the exhaust gas.

[0037] As an example of the present invention, there may be multiple second through holes 33 , and multiple second through holes 33 can increase the speed at which the gas-liquid mixture enters the first gas-liquid separation space 111 , thereby improving the gas-liquid separation efficiency of the gas-liquid separation device 100 .

[0038] The second through hole 33 can be formed in the lower half of the intake pipe 30, so that the gas-liquid mixture of the intake pipe 30 can only enter the first gas-liquid separation space 111 downward along the second through hole 33, so that the direction of the airflow is consistent with the direction of gravity, and the gas-liquid mixture entering the first gas-liquid separation space 111 is directly sprayed onto the lower wall of the first gas-liquid separation space 111. Due to the continuous heat exchange between the inside and the outside of the outer shell 10, the temperature in the gas-liquid separation space 11 can be lower than the exhaust temperature, so that the moisture in the gas-liquid mixture can be precipitated, thereby playing a role in gas-liquid separation, so that the separated liquid moves downward and remains on the lower wall of the first gas-liquid separation space 111, and the separated gas moves upward and enters the second gas-liquid separation space 112 through the first through hole 21 in the upper half of the partition 20, thereby reducing the risk of the liquid being carried away by the airflow when moving downward, thereby improving the gas-liquid separation effect of the gas-liquid separation device 100. Moreover, the utility model can directly utilize the muffler structure for gas-liquid separation design, without the need to design a complex structure separately. The process is simple and easy to implement, which is beneficial to reducing the manufacturing cost of the gas-liquid separation device 100. At the same time, the internal design is cleverly utilized to control the direction of the airflow, combined with the physical gravity direction of the liquid phase, to improve the gas-liquid separation effect of the gas-liquid separation device 100.

[0039] According to the gas-liquid separation device 100 of the embodiment of the utility model, a first through hole 21 is formed in the upper half of the partition 20, and a second through hole 33 is formed in the lower half of the intake pipe 30. This allows the gas-liquid mixture to enter the first gas-liquid separation space 111 from the intake pipe 30. The direction of the airflow and the direction of the liquid gravity are consistent, so that the liquid separated at the lower side of the first gas-liquid separation space 111 can be discharged in time, and the liquid separated at the upper side of the first gas-liquid separation space 111 can be prevented from being directly carried away by the airflow when moving downward, thereby improving the gas-liquid separation effect of the gas-liquid separation device 100. In addition, the gas-liquid separation device 100 has a simple structure and is easy to implement, which is conducive to reducing the manufacturing cost of the gas-liquid separation device 100.

[0040] According to some embodiments of the present invention, Figure 1 As shown, the housing 10 is formed with a first assembly hole 13 , and the air inlet pipe 30 is passed through the first assembly hole 13 and extends into the first gas-liquid separation space 111 .

[0041] Among them, the outer shell 10 can be formed with a first assembly hole 13, and the inner diameter of the first assembly hole 13 can be adapted to the outer diameter of the intake pipe 30, so as to facilitate the intake pipe 30 to smoothly pass through the first assembly hole 13 and extend into the first gas-liquid separation space 111, so that the gas-liquid mixture can enter the first gas-liquid separation space 111 from the intake pipe 30 for gas-liquid separation, thereby achieving the effect of gas-liquid separation of the gas-liquid mixture.

[0042] According to some embodiments of the present invention, Figure 1 As shown, the partition 20 can be sleeved on the outside of the air intake pipe 30. Specifically, the partition 20 can be sleeved on the end of the air intake pipe 30 away from the air inlet 32, and can separate the gas-liquid separation space 11 into a first gas-liquid separation space 111 and a second gas-liquid separation space 112, so that the gas-liquid separation device 100 can perform multiple gas-liquid separations on the gas-liquid mixture, thereby improving the gas-liquid separation effect of the gas-liquid separation device 100. In addition, the partition 20 sleeved on the outside of the air intake pipe 30 can also support the air intake pipe 30, thereby effectively reducing the risk of displacement and shaking of the air intake pipe 30, thereby improving the stability and reliability of the gas-liquid separation device 100.

[0043] According to some embodiments of the present invention, Figure 1 As shown, the partition 20 can be formed with a second assembly hole 22, and the inner diameter of the second assembly hole 22 can be adapted to the outer diameter of the intake pipe 30, so as to facilitate the intake pipe 30 to smoothly pass through the second assembly hole 22. Such a configuration can enable the partition 20 to effectively support the intake pipe 30, thereby further reducing the risk of displacement and shaking of the intake pipe 30, and further improving the stability and reliability of the gas-liquid separation device 100.

[0044] According to some embodiments of the present invention, Figure 1 As shown, a drain port 14 may be formed at the bottom of the housing 10 to discharge the separated liquid in the housing 10 , thereby effectively reducing the risk of water accumulation in the gas-liquid separation device 100 .

[0045] Specifically, the drain port 14 can be provided with a drain pipe 141, so that the liquid separated in the shell 10 can be discharged from the drain port 14. The drain pipe 141 can guide the liquid, thereby reducing the risk of splashing when the separated liquid is discharged from the drain port 14, thereby improving the reliability of the gas-liquid separation device 100.

[0046] As an example of the present invention, at least one drain port 14 is formed at the bottom of the housing 10. For example, one, two, three, or other drain ports 14 may be formed at the bottom of the housing 10. However, the present invention is not limited thereto. Other numbers of drain ports 14 may be formed at the bottom of the housing 10, as long as at least one drain port 14 is formed at the bottom of the housing 10. The drain port 14 may be formed in the first gas-liquid separation space 111 or the second gas-liquid separation space 112, or both the first gas-liquid separation space 111 and the second gas-liquid separation space 112 may be formed with a drain port 14. The present invention is described by taking the first gas-liquid separation space 111 as an example in which a drain port 14 is formed.

[0047] Therefore, by forming a drain port 14 at the bottom of the shell 10, the liquid separated in the gas-liquid separation space 11 can be discharged from the drain port 14 in time, thereby effectively reducing the water accumulation in the gas-liquid separation device 100, thereby improving the safety and reliability of the gas-liquid separation device 100.

[0048] According to some embodiments of the present invention, Figure 1 and Figure 3 As shown, a connecting notch 23 can be formed at the bottom of the partition 20, and the connecting notch 23 connects the first gas-liquid separation space 111 and the second gas-liquid separation space 112, so that the liquid separated in the second gas-liquid separation space 112 can flow into the second gas-liquid separation space 112 through the connecting notch 23, and then the liquid can be discharged from the outer shell 10 through the drain port 14 in the first gas-liquid separation space 111, thereby further effectively reducing the water accumulation in the gas-liquid separation device 100, and further improving the safety and reliability of the gas-liquid separation device 100.

[0049] According to some embodiments of the present invention, Figure 1 , Figure 2 and Figure 4 As shown, the air intake pipe 30 includes an air intake pipe body 34 and a plugging cover 35 . The air intake pipe body 34 is annular, one end of the air intake pipe body 34 is configured as an air inlet 32 ​​, and the plugging cover 35 blocks the other end of the air intake pipe body 34 to define an air intake groove 31 .

[0050] The air intake pipe body 34 may be annular, for example, the air intake pipe body 34 may be a cylindrical body in the shape of a circular ring or an elliptical ring, which is not specifically limited here and may be reasonably set according to actual conditions. Setting the air intake pipe body 34 in an annular shape can effectively reduce the resistance of the gas flow in the air intake pipe body 34, improve the gas transmission efficiency, thereby achieving uniform distribution and stable delivery of the gas, and further improving the separation efficiency of the gas-liquid separation device 100.

[0051] One end of the air inlet pipe body 34 can be configured as an air inlet 32, and the plugging cover 35 can be adapted to the air inlet pipe 30, so that the plugging cover 35 can block the other end of the air inlet pipe body 34 to define the air inlet groove 31, so that the gas-liquid mixture can enter the air inlet groove 31 from the air inlet 32, and because the plugging cover 35 blocks the other end of the air inlet pipe body 34, the flow direction of the gas-liquid mixture in the air inlet groove 31 can be changed, so that the gas-liquid mixture in the air inlet groove 31 can only enter the first gas-liquid separation space 111 through the second through hole 33, and because the second through hole 33 It is formed in the lower half of the air inlet pipe 30 so that the gas-liquid mixture in the air inlet pipe 30 can only enter the first gas-liquid separation space 111 downward along the second through hole 33, so that the direction of the airflow is consistent with the direction of gravity, and the separated liquid moves downward and remains on the lower wall of the first gas-liquid separation space 111, and the separated gas moves upward and enters the second gas-liquid separation space 112 through the first through hole 21 in the upper half of the partition 20, thereby effectively reducing the risk of the liquid being carried away by the airflow when moving downward, thereby significantly improving the gas-liquid separation effect of the gas-liquid separation device 100.

[0052] According to some embodiments of the present invention, Figure 1 As shown, the shell 10 includes: a shell body 15, an air inlet end cover 16 and an air outlet end cover 17. The shell body 15 is annular, and the air inlet end cover 16 and the air outlet end cover 17 are respectively arranged at two ends of the shell body 15. The air inlet pipe 30 is passed through the air inlet end cover 16, and the air outlet end cover 17 is formed with an air outlet 12.

[0053] The shell body 15 may be annular, for example, the shell body 15 may be a cylindrical body in the shape of a circular ring or an elliptical ring, which is not specifically limited here and may be reasonably set according to actual conditions. Setting the shell body 15 in an annular shape can effectively reduce the resistance of the gas flow in the shell body 15, improve the gas transmission efficiency, thereby achieving uniform distribution and stable delivery of the gas, and further improving the separation efficiency of the gas-liquid separation device 100.

[0054] The air inlet cover 16 and the air outlet cover 17 are respectively arranged at the two ends of the shell body 15, and the two ends of the shell body 15 can be blocked, so that the shell 10 defines a gas-liquid separation space 11, and can also prevent impurities from entering the inside of the shell body 15, thereby reducing the risk of failure of the gas-liquid separation device 100. The air inlet pipe 30 is passed through the air inlet cover 16, and the air outlet cover 17 is formed with an air outlet 12, so that the gas-liquid mixture can enter the inside of the shell body 15 through the air inlet pipe 30, and then the gas-liquid mixture is separated into gas and liquid in the gas-liquid separation space 11 inside the shell 10, and the gas separated from the gas-liquid mixture is discharged from the air outlet 12 of the air outlet cover 17, thereby achieving the effect of gas-liquid separation.

[0055] As an example of the present invention, the gas outlet end cover 17 can be formed with a third assembly hole 41, and an gas outlet pipe 40 can be arranged through the third assembly hole 41, and the end of the gas outlet pipe 40 away from the outer shell 10 can be constructed as a gas outlet 12, so that the gas separated in the gas-liquid separation space 11 is discharged in sequence from the gas outlet pipe 40 and the gas outlet 12, thereby achieving the effect of the gas-liquid separation device 100 discharging gas.

[0056] According to some embodiments of the utility model, a silencer mechanism may be provided in the second gas-liquid separation space 112, and the silencer mechanism may be a silencer, thereby the gas-liquid separation device 100 and the silencer mechanism may be integrated, and by providing the silencer mechanism in the second gas-liquid separation space 112, the gas-liquid separation device 100 may have a silencer function.
