In this embodiment, a portion of the first throttling unit 31 is located above the first connecting part 11, and at least a portion of the gas-liquid separation part 40 is located below the first connecting part 11.

[0032] Please see Figures 4-6 and Figure 17The connecting part 10 has a communicating channel, which includes a first communicating channel 121, a second communicating channel 122, a third communicating channel 123, a fourth communicating channel 124, and a fifth communicating channel 125. The first communicating channel 121 has an opening in the mounting part corresponding to the first mounting hole 111, thereby communicating with the first mounting hole 111. The first communicating channel 121 also has an opening in the mounting part corresponding to the second mounting hole 112, thereby communicating with the second mounting hole 112. The second communicating channel 122, the third communicating channel 123, and the fourth communicating channel 124 all have openings in the mounting parts corresponding to the third mounting hole 113, and the second communicating channel 122, the third communicating channel 123, and the fourth communicating channel 124 communicate with the third mounting hole 113.

[0033] The fluid management device includes a first port 101, a second port 102, a third port 103, a fourth port 104, a fifth port 105, and a sixth port 106. These ports serve as inlets or outlets for the refrigerant entering the fluid management device. The ports can be located at the connecting portion 10, or at a pipe or block that is fixedly or partially connected to the connecting portion 10. In this embodiment, the ports are located on the outer wall of the connecting portion 10. Specifically, the first port 101 communicates with the first connecting channel 121, the second port 102 communicates with the second connecting channel 122, the third port 103 communicates with the third connecting channel 123, the fourth port 104 communicates with the fifth connecting channel 125, the fifth port 105 communicates with the sixth connecting channel 126, and the sixth port 106 communicates with the seventh connecting channel 127. In this embodiment, the first port 101 is the refrigerant inlet of the fluid management device, the fourth port 104 is the refrigerant outlet of the fluid management device, the first port 101 and the fourth port 104 are located on the same wall of the connecting part 10, the second port 102 and the third port 103 are located on the same wall of the connecting part 10, and the fifth port 105 and the sixth port 106 are located on the same wall of the connecting part 10, which facilitates the connection of the fluid management device with other components in the thermal management system.

[0034] In this embodiment, the first connecting channel 121 is a straight hole. For ease of description, a first surface is defined, which is perpendicular to the axis of the first cavity. The projection of the first connecting channel 121 onto the first surface is perpendicular to the projections of the second connecting channel 122 and the third connecting channel 123 onto the first surface. Along the axial direction of the first connecting channel 121, the first opening 101 is located on one side of the first mounting hole 111, the second mounting hole 112 is located on the other side of the first mounting hole 111, at least a portion of the second connecting channel 122 is located on one side of the third mounting hole 113, and the third connecting channel 123 is located on the other side of the third mounting hole 113. This makes the mounting holes and connecting channels relatively compact, reducing the processing difficulty and the volume of the connecting portion 10.

[0035] The first valve unit 21 enables communication between the first connecting channel 121 and the second connecting channel 122. The first valve unit 21 can be a solenoid valve or other type of on / off valve. In this embodiment, the first valve unit 21 is a solenoid valve, which can be a normally open or normally closed solenoid valve. The first throttling unit 31 enables communication between the first connecting channel 121 and the third connecting channel 123 by adjusting the first throttling unit 31. The first throttling unit 31 can be an electronic expansion valve or other type of throttling valve. In this embodiment, the first throttling unit 31 is an electronic expansion valve. The second valve unit 22 enables communication between one of the second connecting channels 122 and the third connecting channel 123 and the fourth connecting channel 124. The second valve unit 22 is a three-way valve. In this embodiment, the second valve unit 22 is a three-way ball valve. The second valve unit 22 has two operating states: in one operating state, the second connecting channel 122 is connected to the fourth connecting channel 124 via the second valve unit 22; in the other operating state, the third connecting channel 123 is connected to the fourth connecting channel 124 via the second valve unit 22.

[0036] Please see Figure 17 At least a portion of the second throttling unit 32 is located in the fourth mounting hole 114, and at least a portion of the third throttling unit 33 is located in the fifth mounting hole 115. The connecting portion 10 has a sixth connecting channel 126, a seventh connecting channel 127, and an eighth connecting channel 128. The sixth connecting channel 126 has an opening in the mounting portion corresponding to the fourth mounting hole 114 and connects to the fourth mounting hole 114. The seventh connecting channel 127 has an opening in the mounting portion corresponding to the fifth mounting hole 115 and connects to the fifth mounting hole 115. In one operating state of the fluid management device, the fifth port 105 is an inlet of the fluid management device 100. By adjusting the second throttling unit 32, the sixth connecting channel 126 and the seventh connecting channel 127 can be connected, and part of the refrigerant flows out from the sixth port 106. By adjusting the third throttling unit 33, the seventh connecting channel 127 can be connected to the eighth connecting channel 128, and another part of the refrigerant enters the eighth connecting channel 128 through the third throttling unit. Of course, by adjusting the third throttling unit 33, the seventh connecting channel 127 and the eighth connecting channel 128 can also be disconnected. In another operating state of the fluid management device... In this state, by adjusting the seventh connecting channel 127 of the second throttling unit 32 to connect with the sixth connecting channel 126, and by adjusting the seventh connecting channel 127 of the third throttling unit 33 to connect with the eighth connecting channel 128, the sixth port becomes an inlet of the fluid management device 100. Part of the refrigerant in the seventh connecting channel 127 enters the sixth connecting channel 126 through the second throttling unit and then flows out through the fifth port 105. Another part of the refrigerant enters the eighth connecting channel 128 through the third throttling unit. In other embodiments, one of the second throttling unit 32 and the third throttling unit 33 can also be adjusted to make the corresponding channel disconnected.

[0037] The first chamber is a gas-liquid separation chamber of the fluid management device, used to separate the liquid and gas components of the refrigerant. The gas-liquid separation section 40 includes a cylindrical section, which is fixedly connected or limitedly connected to the connecting section 10. In this embodiment, the connection method is welding. The gas-liquid separation section 40 also includes components for enhancing gas-liquid separation, such as an umbrella section and a return pipe, which will not be described in detail. The fourth connecting channel 124 has an opening in the connecting section 10 facing the first chamber. The first chamber communicates with the fourth connecting channel 124. The fifth connecting channel 125 communicates with the first chamber through the cavity of the return pipe. The fourth connecting channel 124 is located in the inlet channel of the first chamber, and the fifth connecting channel 125 is at least a partial outlet channel of the first chamber.

[0038] The fluid management device 100 includes a first operating mode and a second operating mode. In the first operating mode, the first valve unit 21 connects the first connecting channel 121 with the second connecting channel 122, the second valve unit 22 connects the third connecting channel 123 with the fourth connecting channel 124, and the second valve unit 22 disconnects the second connecting channel 122 from the fourth connecting channel 124. The first throttling unit 31 disconnects the first connecting channel 121 from the third connecting channel 123. Thus, the refrigerant enters the first connecting channel 121 through the first port 101, then enters the second connecting channel 122 and exits the fluid management device 100 through the second port 102. The refrigerant entering the third connecting channel 123 through the third port 103 enters the fourth connecting channel 124 and the first chamber through the second valve unit 22. After gas-liquid separation in the first chamber, the refrigerant leaves the fluid management device 100 through the fifth connecting channel 125. The refrigerant enters the sixth connecting channel 126 through the fifth port 105, and after being throttled by the second throttling unit 32, it enters the seventh connecting channel 127. In the seventh connecting channel 127, part of the refrigerant leaves the fluid management device 100 through the sixth port 106, and part of the refrigerant enters the eighth connecting channel 128 after being throttled again by the third throttling unit 33. In the second operating mode of the fluid management device 100, the first valve unit 21 disconnects the first connecting channel 121 from the second connecting channel 122, the second valve unit 22 disconnects the third connecting channel 123 from the fourth connecting channel 124, and the second valve unit 22 connects the second connecting channel 122 to the fourth connecting channel 124. The first throttling unit 31 connects the first connecting channel 121 to the third connecting channel 123. In this way, the refrigerant enters the first connecting channel 121 through the first port 101, then enters the third connecting channel 123, and exits the fluid management device 100 through the second port 102. The refrigerant that enters the second connecting channel 122 through the second port 102 enters the fourth connecting channel 124 and the first chamber through the second valve unit 22. After gas-liquid separation in the first chamber, the refrigerant leaves the fluid management device 100 through the fifth connecting channel 125. The refrigerant enters the seventh connecting channel 127 through the sixth port 106. Part of the refrigerant is throttled by the second throttling unit 32 and enters the sixth connecting channel 126, then flows out through the fifth port 105. The other part of the refrigerant is throttled by the third throttling unit 33 and enters the eighth connecting channel 128.

[0039] The connecting part 10 can be a block, and the connecting channel and the mounting hole can be machined; the connecting part 10 can also be a casting, and the connecting channel and the mounting hole can be formed by casting or machining; the connecting part 10 can also be a forging, and two or more separate parts can be formed by forging and welding or bonding to form a connecting channel.

[0040] The fluid management device 100 integrates the gas-liquid separation unit 40, the valve unit, and the throttling unit into a single unit. The fluid management device is connected to the thermal management system as a whole, making assembly convenient. By providing a connecting channel and corresponding valve unit and throttling unit in the connection part 10, the valve unit controls the opening and closing of the flow channel, and the throttling unit adjusts the refrigerant flow to meet the needs of at least two modes of the thermal management system. Since the channel is formed inside the connection part 10, the connection point of the connecting channel is located inside the connection part 10, reducing external leakage of the connecting channel connection.

[0041] Please see Figures 1-6 The fluid management device 100 may further include a third valve unit 23 and a fourth valve unit 24. Accordingly, the connecting portion 10 has a sixth mounting hole 116 and a seventh mounting hole 117. At least a portion of the third valve unit 23 is located in the sixth mounting hole 116, and at least a portion of the fourth valve unit 24 is located in the seventh mounting hole 117. The third valve unit 23 is fixedly connected to or limitedly connected to the connecting portion 10, and the fourth valve unit 24 is fixedly connected to or limitedly connected to the connecting portion 10. The sixth connecting channel 126 includes a first segment 1261 and a second segment 1262. The first segment 1261 is connected to the fifth port 105. A part of the first segment 1261 is connected to the fourth mounting hole 114, and another part of the first segment 1261 is connected to the sixth mounting hole 116. The second segment 1262 is connected to the fifth mounting hole 115. The connection between the second segment 1262 and the fifth mounting hole 115 can be a direct connection or an indirect connection. A direct connection includes the second segment 1262 having an opening in the mounting portion corresponding to the fifth mounting hole 115. An indirect connection includes the second segment 1262 being connected to the fifth mounting hole 115 through the seventh mounting hole 117. The third valve unit 23 enables the first segment 1261 to connect to the second segment 1262, thereby connecting the first segment 1261 to the fifth mounting hole 115. The third valve unit 23 can be a solenoid valve, which controls the opening and closing of the solenoid valve to connect or disconnect the first segment 1261 from the second segment 1262. In this embodiment, the third valve unit 23 is a one-way valve, which enables the first segment 1261 to unidirectionally connect to the second segment 1262.

[0042] The seventh connecting channel 127 includes a first sub-segment 1271, a second sub-segment 1272, and a third sub-segment 1273. The first sub-segment 1271 is connected to the sixth port 106 and the seventh mounting hole 117. The second sub-segment 1272 is connected to the fifth mounting hole 115. Along the refrigerant flow direction, the seventh mounting hole 117 is located between the first sub-segment 1271 and the second sub-segment 1272. The fourth valve unit 24 enables the first sub-segment 1271 to connect with the second sub-segment 1272. When the sixth port 106 is an inlet of the fluid management device, the refrigerant entering the fluid management device through the sixth port 106 can enter the second sub-segment 1272 through the fourth valve unit 24. The third sub-segment 1273 is connected to the sixth port 106 and to the fourth mounting hole 114. Along the refrigerant flow direction, the fourth mounting hole 114 is located between the first segment 1261 and the third sub-segment 1273. The third sub-segment 1273 can be connected to the first segment 1261 via the second throttling unit 32. It can be seen that the second throttling unit 32 has a bidirectional throttling function. The fourth valve unit 24 can be a solenoid valve, controlling the opening and closing of the solenoid valve to connect or disconnect the first sub-segment 1271 from the second sub-segment 1272. In this embodiment, the fourth valve unit 24 is a one-way valve, enabling the first sub-segment 1271 to unidirectionally connect to the second sub-segment 1272.

[0043] The fluid management device 100 may further include a heat exchange section 50, which includes a first flow channel and a second flow channel. The first and second flow channels are not connected to each other, but the fluid in the first and second flow channels can exchange heat. In this embodiment, the heat exchange section 50 is a plate heat exchanger. The fluid in the first flow channel includes refrigerant, and the fluid in the second flow channel includes coolant. The connecting section 10 has a connecting surface (not shown) facing the heat exchange section 50. The connecting surface is located on the lower wall of the connecting section 10 and is welded to the heat exchange section 50. The outlet of the eighth connecting channel 128 is located on the connecting surface, and the eighth connecting channel 128 communicates with the first flow channel. It can be seen that the heat exchange section 50 and the gas-liquid separation section 40 are located on one side of the connecting section 10, and part of the valve unit and part of the throttling unit are located on the other side of the connecting section 10. In this way, the center of mass of the fluid management device is relatively close to the center of the fluid management device, which is beneficial to improving the stability of the fluid management device.

[0044] In this implementation, please refer to Figure 6The fourth connecting channel 124 includes a first sub-section 1241, a second sub-section 1242, and a third sub-section 1243. The first sub-section 1241 is perpendicular to the axis of the first cavity, and the second sub-section 1242 is parallel to the axis of the second cavity. The first sub-section 1241 has an opening in the mounting portion corresponding to the third mounting hole 113 and communicates with the third mounting hole 113. The second sub-section 1242 communicates with the first cavity, and the third sub-section 1243 has an opening in the connecting surface and communicates with the first flow channel. The refrigerant passing through the third throttling unit 33 can enter the first flow channel of the heat exchange section 50 through the eighth connecting channel 128, and then enter the first cavity through the third sub-section 1243.

Specifically, the connecting part 10 includes a first connecting part 11 and a second connecting part 12. The first connecting part 11 and the second connecting part 12 are fixedly connected or limitedly connected. The gas-liquid separation part 40 is fixedly connected or limitedly connected to the first connecting part 11, and the heat exchange part 50 is fixedly connected or limitedly connected to the second connecting part 12. The connection method can be welding, bonding, or bolt connection. The first mounting hole 111, the second mounting hole 112, the third mounting hole 113, the first connecting channel 121, the second connecting channel 122, the second connecting channel 122, and at least part of the fourth connecting channel 124 are located in the first connecting part 11. The first port 101, the second port 102, the third port 103, and the fourth port 104 are located in the first connecting part 11. The fourth mounting hole 114, the fifth mounting hole 115, the sixth mounting hole 116, the seventh mounting hole 117, the sixth connecting channel 126, the seventh connecting channel 127, and the eighth connecting channel 128 are located in the second connecting part 12.
