[0028] The fluid management device of this application can be applied to a vehicle thermal management system, including new energy vehicles, and the fluid includes at least coolant. The invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] Please see Figures 1-12 as well as Figures 15-20The fluid management device 10 includes a connector 100, a reservoir 200, and an electric valve 300. The reservoir 200 includes a reservoir housing 210 and has a cavity (not shown) located within the reservoir housing 210. The reservoir cavity can contain coolant. The reservoir housing 210 can be a single piece or composed of two or more housings connected together. The reservoir housing 210 includes a first mating part 211. The connector 100 includes a first interface part 120 and a second interface part 130. The connector 100 also has a flow channel 110 located within the connector 100. The first mating part 211 is fixedly connected to or limited by the first interface part 120 and sealed at the connection, thereby communicating between the reservoir cavity and the flow channel. The connection method can be welding, bonding, insertion, snap-fit, or threaded connection. In one specific embodiment, at least a portion of the first interface portion 120 is located in the cavity formed by the first mating portion 211. The fluid management device may also provide a sealing ring between the first mating portion 211 and the first interface portion 120 to enhance the sealing performance. Of course, the first mating portion 211 may also be located in the cavity formed by the first interface portion 120, which will not be described in detail here. The electric valve 300 includes a valve body 350, a valve stem 330, an electronic control unit 320, and a valve core 340. The electronic control unit 320 is drivenly connected to the valve stem 330, and the valve stem 330 is fixedly connected or limitedly connected to the valve core 340. The valve body 350 has a first receiving cavity 352, and at least a portion of the valve core 340 is located in the first receiving cavity 352. The electronic control unit 320 can drive the valve stem 330 to cause the valve core 340 to move in the first receiving cavity 352. The movement of the valve core 340 in the first receiving cavity 352 includes rotation about the valve stem 330 as an axis and / or axial movement along the valve stem 330. In this embodiment, the valve core 340 can rotate at a certain angle about the valve stem 330 as an axis. The valve housing 350 includes a second mating part 353, which is sealed to the second interface part 130. The valve housing 350 has a channel 355 that can communicate with the first receiving cavity 352. The channel 355 communicates with the flow channel 110, and thus the flow channel can communicate with the first receiving cavity 352.

[0030] The axial direction of the valve stem 330 is defined as vertical. The electronic control unit 320 is located above the valve core 340, and at least part of the connector 100 is located below the reservoir housing 210. In this embodiment, when the fluid management device 10 is working, the fluid inside the fluid management device 10 is coolant. The fluid management device 10 is provided with a connector 100, which has a flow channel 110 that connects the reservoir cavity and the first receiving cavity 352. The electric valve 300 is connected to the connector 100. The electronic control unit 320 is located above the valve core 340, that is, above the first receiving cavity 352. This reduces the probability of coolant in the first receiving cavity entering the electronic control unit 320, which helps prevent coolant from damaging the live parts of the electronic control unit, thereby increasing the service life of the electronic control unit 320 and thus increasing the service life of the fluid management device. At least part of the connector 100 is located below the tank housing 210, which facilitates communication between the coolant in the tank cavity and the coolant in the flow channel when the fluid management device 10 is actually used.

[0031] Please see Figures 3-5 The connector 100 includes a first side portion 170 facing the bottom 212 of the reservoir housing. A first interface portion 120 protrudes relative to the first side portion 170 towards the bottom 212 of the reservoir housing. A first mating portion 211 is formed on the bottom 212 of the reservoir housing. Thus, the connector 100 is located below the reservoir housing 210, facilitating the flow of coolant to the fluid management device 10. The opening of the second interface portion 130 faces the bottom 212 of the reservoir housing. Along the axial direction of the valve stem 330, the electronic control portion 320 is closer to the bottom 212 of the reservoir housing than the second interface portion 130. At least a portion of the connector 100 is located below the reservoir housing 210, and the electric valve 300 is also located below the reservoir housing 210. This makes the structure of the fluid management device 10 relatively compact, and the center of gravity is relatively close to the geometric center of the fluid management device 10, which also contributes to the structural stability of the fluid management device 10. In other embodiments, the opening of the first interface portion 120 may also be located on the first side portion 170, with the opening of the first interface portion 120 facing the bottom 212 of the kettle shell.

[0032] The fluid management device 10 includes a first mounting portion 150 and a mating portion 150' of the first mounting portion. One of the first mounting portion 150 and the mating portion 150' is located in the kettle housing 210, and the other is located in the connector 100. The first mounting portion 150 and the mating portion 150' cooperate with each other to achieve a fixed connection between the connector and the kettle. In this embodiment, the first mounting portion 150 is located in the connector 100, and the first mounting portion 150 is formed as a threaded hole. The mating portion 150' is a through hole. The first mounting portion and the mating portion 150' are connected by bolts, thereby fixing or limiting the connection between the connector 100 and the kettle housing 210. The fluid management device 10 includes a second mounting portion 160 and a mating portion 160' of the second mounting portion. One of the second mounting portion 160 and the mating portion 160' is located in the kettle housing 210, and the other is located in the valve housing 350. The two cooperate with each other to fix the electric valve to the connector. The connection method between the second mounting part 160 and the mating part 160' of the second mounting part may be the same as or different from the connection method between the first mounting part and the mating part 150' of the first mounting part, and will not be described in detail here. In a more specific embodiment, along the radial direction of the first receiving cavity 352, the second mounting part is closer to the first receiving cavity 352 than the first mounting part, and the fixing point of the electric valve is closer to the center than the fixing point of the kettle, which helps to stabilize the structural performance of the fluid management device 10.

[0033] Please see Figure 5 , Figure 6 and Figures 10-12 The valve housing 350 includes a main body 354, which includes a first receiving portion 351 having a first receiving cavity 352. The second interface portion 130 includes a second receiving portion 131 having a second receiving cavity 132. At least a portion of the main body 354 is located within the second receiving cavity 132. In this embodiment, a second mating portion 353 is formed on the outer wall 3542 of the main body, and a channel is formed on the main body 354. Along the radial direction of the first receiving cavity 352, the channel 355 penetrates the main body 354. The channel 355 has openings on both the inner and outer walls 3542 of the main body. Correspondingly, a flow channel 110 has an opening on the wall 1311 of the second receiving portion, with the flow channel opening opposite to at least a portion of the channel opening, thus communicating with the corresponding channel 355. In other embodiments, the channel may also be formed on the bottom of the valve housing. The main body 354 being at least partially located in the second receiving portion 131 reduces the volume of the fluid management device 10, resulting in a compact structure. In this embodiment, the main body 354 is cylindrical. In other embodiments, the main body may be square or other shapes.

[0034] The fluid management device 10 includes a seal 400 located in the second receiving cavity 132. The seal 400 is distributed around the channel opening. One side of the seal 400 contacts the wall 1311 of the second receiving cavity, and the other side contacts the outer wall of the main body 354. The seal 400 is in a compressed state to ensure a sealing effect. The seal 400 has a communication port 401, through which the flow channel opening communicates with the channel opening. The seal 400 can be a sealing ring. When the seal 400 is a sealing ring, the main body and / or the connecting member 100 can be provided with a groove to accommodate the sealing ring. The seal 400 can also be a sealing gasket. The electric valve 300 has multiple channel openings, and the number of seals 400 matches the number of channel openings. These seals 400 can be independent components or an integral structure.

[0035] In this embodiment, the seal 400 is an integral structure, cylindrical in shape to match the shape of the main body 354. The side portion 410 of the seal abuts against the outer wall 3542 of the main body and the wall of the second receiving portion 131. The seal 400 has a receiving cavity 402, at least a portion of the main body 354 is located in the receiving cavity 402 of the seal, and a connecting port 401 is formed on the side portion 410 of the seal. Correspondingly, a channel port is formed on the main body 354, and a flow channel port is formed on the side wall of the second receiving portion 131. The fluid management device 10 may also include a rib 500, which compresses the seal 400 to enhance the seal. Specifically, the rib 500 includes a first ring portion 510, a second ring portion 520, and at least two axial portions 530 along the axial direction of the valve stem 330. One end of the axial portion 530 is connected to the first ring portion 510, and the other end of the axial portion 530 is connected to the second ring portion 520. The rib 500 is formed on the valve housing 350, and the rib 500 protrudes towards the second receiving portion 131 relative to the outer wall 3542 of the main body portion. The channel opening is located between adjacent axial portions 530. Thus, the channel opening is located within the area enclosed by the rib 500, and the fluid management device 10 can improve sealing performance by providing the rib 500. In other embodiments, the rib 500 may also be formed on the connector 100, and the rib 500 protrudes towards the main body portion 354 relative to the wall of the second receiving portion 131, with the flow channel opening located between adjacent axial portions 530. This will not be described in detail further. In other embodiments, the fluid management device may not have a separate seal. The rib directly contacts the inner wall of the second receiving part, and the rib has a sealing function. The material of the rib may be different from the material of other parts of the main body. The rib and the other materials of the main body are integrally injection molded.

[0036] In this implementation, please refer to Figure 8The electric valve 300 is a five-way valve, and the valve body 350 has five channels, namely, the channels of the electric valve 300 include a first channel 3551, a second channel 3552, a third channel 3553, a fourth channel 3554, and a fifth channel 3555. All five channels penetrate the main body. Correspondingly, the fluid management device 10 has five flow channels, namely, a first flow channel 111, a second flow channel 112, a third flow channel 113, a fourth flow channel 114, and a fifth flow channel 115. These five flow channels have flow ports on the side wall 1311 of the second receiving part. The first flow channel 111 communicates with the first channel, the second flow channel 112 communicates with the second channel, the third flow channel 113 communicates with the third channel, the fourth flow channel 114 communicates with the fourth channel, and the fifth flow channel 115 communicates with the fifth channel.
