[0029] The stacking direction of the first plate 1110 and the second plate 1120 is defined as the first direction. The connector 1000 includes a first side portion 1030 and a second side portion 1040. Along the first direction of the connector 1000, the first side portion 1030 is located on one side of the connector 1000, and the second side portion 1040 is located on the opposite side of the connector 1000. In this embodiment, the first side portion 1030 is located outside the first plate 1110, and the second side portion 1040 is located outside the second plate 1120. The connector 1000 also includes an interface portion 1200. The axial direction of the interface portion 1200 is the first direction or parallel to the first direction. The interface portion 1200 has at least one interface cavity 1201.

Of course, in other embodiments, the interface portion may also be located on one of the first side portion 1030 and the second side portion 1040, or in other words, the interface portion may be located on either the first side portion 1030 or the second side portion 1040, which will not be described in detail here.

[0030] In other embodiments, the connector 1000 may also include three or more plates 1100, which are arranged in layers. Adjacent plates 1100 are fixedly and sealed together. At least one of the adjacent plates 1100 has at least one flow channel portion inside, forming a coolant flow channel 1010 at the flow channel portion. Along a first direction of the connector 1000, one of the two sides of at least one plate has an interface portion and / or a flow channel portion.

The first interface part 1210 can be one, two, or more; correspondingly, the mating part 2410 of the liquid storage device can also be one, two, or more. In this embodiment, there are three first interface parts 1210, and correspondingly, there are also three mating parts of the liquid storage device. The connector 1000 also includes a first mounting part (not labeled), and correspondingly, the liquid storage device 2400 includes a mounting mating part.

This reduces the number of connections of the fluid management device 100 and lowers the probability of leakage.

[0032] Please see Figures 1-4The fluid management device 2000 also includes an electric valve 2200. In this embodiment, the electric valve 2200 is a five-way water valve, and there are two electric valves 2200, namely a first electric valve 2201 and a second electric valve 2202.

The second interface part 1220 that mates with the electric valve 2200 is defined as the interface part 1122 of the electric valve. The interface part 1122 of the electric valve includes a first... Platform 1130, the interface portion 1122 of the electric valve has five connection ports formed on the first platform 1130, and the five connection ports are respectively connected to five corresponding coolant flow channels 1010. Correspondingly, the electric valve 2200 has five corresponding mating ports, which are located on the mating portion 2210 of the electric valve. The mating ports of the electric valve are at least partially opposite to the corresponding connection ports located on the first platform 1130, thereby connecting the coolant flow channel 1010 of the connector 1000 to the corresponding mating ports. To enhance the sealing performance between the electric valve 2200 and the connector 1000, a sealing element may be provided between the mating portion 2210 and the interface portion 1122 of the electric valve, which will not be described in detail here. In other embodiments, the mating portion 2210 of the electric valve may also be located on a pipe connected to the valve body of the electric valve, in which case the pipe of the electric valve is sealed to the connector 1000. The connector 1000 also includes a second mounting portion 1060. Correspondingly, the electric valve 2200 includes a mounting mating portion, and the second mounting portion 1060 is bolted to the mounting mating portion of the electric valve. Of course, the second mounting portion and the mounting mating portion of the electric valve can also be fixed by other methods, such as adhesive bonding or welding. Similarly, the interface portion of the second electric valve includes a second platform, and a second connection port is located on the second platform. The second electric valve includes a second valve body, and the mating portion of the second electric valve is formed on the second valve body.

Figure 10The interface portion 1221 of the electric pump includes a first bottom wall 1123 and a first side wall 1124. At least a portion of the electric pump 2100 is located in the interface cavity of the interface portion. The interface portion 1221 of the electric pump has a first interface 1125 and a second interface 1126. The first interface 1125 and the second interface 1126 are respectively connected to the corresponding coolant flow channels 1010. The first interface 1125 is located in the first bottom wall 1123, and the second interface 1126 is located in the first side wall 1124. One of the inlet and outlet of the electric pump 2100 is at least partially opposite to the first interface 1125, and the other is at least partially opposite to the second interface 1126. Thus, when the electric pump 2100 is working, the electric pump 2100 can pump coolant from one coolant flow channel to another coolant flow channel. In other embodiments, the electric pump 2100 may include an outlet pipe and an inlet pipe. In this case, the electric pump has two interface portions 1221, and the outlet pipe and inlet pipe are sealed to the interface portions 1221. This will not be described in detail.

The liquid storage device 2400, electric valve 2200, and electric pump 2100 are located on opposite sides of the connector 1000, resulting in a compact structure and a small footprint for the fluid management device 100. Of course, at least one of the electric valve 2200 and the electric pump 2100 may also be located on the same side of the connector 1000 as the liquid storage device 2400, which will not be described in detail here. Alternatively, the fluid management device 2000 may also include one or two of the liquid storage device 2400, the electric valve 2200, and the electric pump 2100.

The first heat exchanger 2310 includes a refrigerant passage and a coolant passage, and the second heat exchanger 2320 also includes a refrigerant passage and a coolant passage. When the fluid management device 100 is operating, the refrigerant passage of the first heat exchanger 2310 is a high-pressure passage, and the refrigerant... The refrigerant passage of the first heat exchanger 2310 can release heat to the coolant in the coolant passage of the first heat exchanger 2310, heating the coolant in the coolant passage of the first heat exchanger 2310. The refrigerant flow channel of the second heat exchanger 2320 is a low-pressure channel, and the refrigerant in the refrigerant flow channel of the second heat exchanger 2320 can absorb the heat of the coolant in the coolant passage of the second heat exchanger 2320. The third heat exchanger 2330 includes two coolant passages, and the coolant in the two coolant flow channels of the third heat exchanger 2330 can exchange heat.

[0038] The mating parts of the heat exchangers include a first heat exchanger mating part 2311, a second heat exchanger mating part 2321, and a third heat exchanger mating part 2331. The first heat exchanger mating part 2311 is welded and sealed to the second interface part 1220, thereby connecting the coolant channel of the first heat exchanger 2310 to the coolant flow channel of the connector 1000.

It is understood that when the fluid management device 2000 includes a solenoid valve component 2520, a throttling component 2530, and a one-way component, the valve body 2500 has a receiving cavity corresponding to the solenoid valve component 2520, a receiving cavity corresponding to the throttling component 2530, and a receiving cavity corresponding to the one-way component. At least a portion of the solenoid valve component 2520, the throttling component 2530, and the one-way component 2540 are located in their respective receiving cavities. The solenoid valve component 2520, the throttling component 2530, and the one-way component 2540 are fixedly connected or limitedly connected to the valve body 2500. The valve body 2500 has a valve body passage. A solenoid valve component 2520 is used to open and close the corresponding valve body passage. A throttling component 2530 throttles and reduces the pressure of the refrigerant flowing through it. A one-way component ensures unidirectional flow through the valve body passage, connecting it to the refrigerant passage of the first heat exchanger 2310. The valve body passage also connects to the refrigerant passage of the second heat exchanger 2320.
