The first inlet 101, the first outlet 102, the second inlet 103, and the second outlet 104 are all located at the same end of the outer shell 1.

[0023] The first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104 in the gas-liquid separation device of the present application are located at the same end of the shell 1. When the gas-liquid separation device is installed, the pipelines connected to the first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104 can be located on the same side of the shell 1, that is, the pipelines connected to the first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104 can extend from the same end of the shell 1 to reduce the installation space required.

[0024] According to a specific embodiment of the present application, referring to FIG. 1 to FIG. 5 , the gas-liquid separation device includes a heat exchange mechanism 3 , which can complete a heat exchange process for the heat exchange medium entering the gas-liquid separation device.

[0025] In this embodiment, the gas-liquid separation device includes a shell 1, which has a first inlet 101 and a first outlet 102 located on the same side of the shell 1, that is, the shell 1 has a first inlet 101 and a first outlet 102, wherein the first inlet 101 and the first outlet 102 are located at the same end of the shell 1.

[0026] When the gas-liquid separation device is in operation, the first heat exchange medium can enter the gas-liquid separation device from the first inlet 101 , complete heat exchange in the gas-liquid separation device, and then flow out of the gas-liquid separation device from the first outlet 102 .

[0027] The gas-liquid separation device of this embodiment includes an inner cylinder assembly 4 and a heat exchange mechanism 3. The inner cylinder assembly 4 is at least partially located in the outer shell 1. The inner cylinder assembly 4 has a first accommodating chamber 401. The gas-liquid separation device has a second accommodating chamber 107 located between the inner cylinder assembly 4 and the outer shell 1. The first inlet 101 is connected to the first accommodating chamber 401, the first outlet 102 is connected to the second accommodating chamber 107, and the first accommodating chamber 401 is connected to the second accommodating chamber 107.

[0028] The heat exchange mechanism 3 is located between the outer shell 1 and the inner cylinder assembly 4. The heat exchange mechanism 3 has a heat exchange channel. The outer shell 1 also has a second inlet 103 and a second outlet 104. The second inlet 103 and the second outlet 104 are both connected to the heat exchange channel.

[0029] In this embodiment, the gas-liquid separation device includes a partition 2 , the first inlet 101 and the first outlet 102 are located on the same side of the partition 2 , and the second inlet 103 and the second outlet 104 are located on the other side of the partition 2 .

[0030] The partition 2 is located on a side of the housing 1 close to the first end cover 15 .

[0031] The second accommodating chamber 107 includes a first cavity 105 and a second cavity 106. The first inlet 101 is connected to the first cavity 105, and the first outlet 102 is connected to the second cavity 106. When the gas-liquid separation device is in operation, the first heat exchange medium can enter the first cavity 105 through the first inlet 101, flow through the outer surface of the heat exchange mechanism 3, and flow out of the second cavity 106 through the first outlet 102. The second heat exchange medium can enter the inner cavity of the heat exchange mechanism 3 through the second inlet 103 and flow out of the inner cavity of the heat exchange mechanism 3 through the second outlet 104.

[0032] In the present application, the first heat exchange medium and the second heat exchange medium can be the same type of fluid, for example, they can be fluids in two intervals of a system circulation loop. Of course, depending on the use requirements, the first heat exchange medium and the second heat exchange medium can also be different types of fluids, or they can be the same type of fluid in different circulation loops.

[0033] The first cavity 105 and the second cavity 106 are located on opposite sides of the partition 2, which is used to separate the first cavity 105 and the second cavity 106. The first cavity 105 and the second cavity 106 are isolated from each other at the location of the partition 2. The end of the first cavity 105 away from the partition 2 is connected to the end of the second cavity 106 away from the partition 2. The first inlet 101 is connected to the end of the first cavity 105 near the partition 2, and the first outlet 102 is connected to the end of the second cavity 106 near the partition 2. The gas-liquid separation device has a first heat exchange path from the first cavity 105 through the outer surface of the heat exchange mechanism 3 and into the second cavity 106.

[0034] That is, when the gas-liquid separation device is working, the first heat exchange medium entering the gas-liquid separation device from the first inlet 101 can enter the first cavity 105 and flow from the first cavity 105 to the second cavity 106; when flowing through the outer surface of the heat exchange mechanism 3, it exchanges heat with the second heat exchange medium in the inner cavity of the heat exchange mechanism 3; and can flow from the second cavity 106 to the first outlet 102, and can flow out of the gas-liquid separation device from the first outlet 102.

[0035] In this embodiment, the gas-liquid separation device further has a second inlet 103 and a second outlet 104 , and the first inlet 101 , the first outlet 102 , the second inlet 103 and the second outlet 104 are all located on the same side of the housing 1 .

[0036] The applicant found that during the installation process of the gas-liquid separation device in the related art, the four ports of the gas-liquid separation device are unevenly arranged on both sides of the gas-liquid separation device, that is, three of the ports are located on the same side of the gas-liquid separation device, and the other port is located on the opposite side of the gas-liquid separation device. As a result, when the ports on both sides of the gas-liquid separation device are connected to the pipelines, the pipelines located on both sides of the gas-liquid separation device will occupy a certain space, resulting in a larger installation space required for the entire gas-liquid separation device; the applicant found that if all four ports are moved to the same side of the gas-liquid separation device, then the four pipelines connected to the four ports can be located on the same side of the gas-liquid separation device at the same time, and the installation space occupied by them is concentrated on one side of the gas-liquid separation device, and the installation space occupied on the other side of the heat exchanger is relatively reduced, thereby reducing the installation space occupied by the entire gas-liquid separation device.

[0037] In response to the above findings, this embodiment adjusts the port distribution of the gas-liquid separation device, and adjusts the four ports originally located on both sides of the gas-liquid separation device to the same side of the gas-liquid separation device. That is, the first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104 in this embodiment are adjusted to the same end of the shell 1 in the gas-liquid separation device, so that when the gas-liquid separation device is installed, the four pipelines located at the first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104 are located on the same side of the shell 1, thereby reducing the installation space required for the entire gas-liquid separation device.

[0038] In addition, the applicant also found that the design of locating the first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104 on the same side of the shell 1 also facilitates the installation process of the corresponding arrangements at the first inlet 101, the first outlet 102, the second inlet 103 and the second outlet 104, making the pipeline installation easier to operate, and at the same time, the layout of the pipeline becomes simpler and more compact after the improvement.
