Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0021] According to the first aspect of this application, Figure 1 As shown, a thermal management system is provided, including: a control valve and a heat exchanger 200, the heat exchanger 200 including a flow channel 210, the control valve being adapted to control the flow of refrigerant through the entire flow channel 210, or the control valve being adapted to control the flow of refrigerant through a portion of the flow channel 210.
[0022] Using the above method, when the heat exchange demand is large, all flow channels can be used for heat exchange; when the heat exchange demand is small, only some flow channels can be used for heat exchange, thus meeting various heat exchange needs.
[0023] In some embodiments, such as Figure 2-4As shown, the flow channel 210 includes several interconnected processes. The starting point of the first process is connected to the first inlet 221. The starting point or ending point of any process other than the first and last processes is connected to the second inlet 222. The ending point of the last process is connected to the first outlet 231. Refrigerant is suitable to flow into the flow channel 210 through the first inlet 221 or the second inlet 222, and to flow out of the flow channel 210 through the first outlet 231. In this way, refrigerant flows into the flow channel 210 through the first inlet 221 and out of the flow channel 210 through the first outlet 231, thus circulating through the entire flow channel 210, at which point the heat exchanger 200 performs its full heat exchange function. Alternatively, refrigerant flows into the flow channel 210 through the second inlet 222 and out of the flow channel 210 through the first outlet 231, thus circulating through a portion of the flow channel 210, at which point the heat exchanger 200 performs only a portion of the heat exchange function.
[0024] In some embodiments, the heat exchanger 200 further includes a first manifold 241 and a second manifold 242, and a flow channel 210 is disposed between the first manifold 241 and the second manifold 242. The flow channel 210 includes a first flow path 211, a second flow path 212, a third flow path 213, and a fourth flow path 214. The first inlet 221 is located on the first manifold 241 at a position corresponding to the starting point of the first process 211. The starting point of the first process 211 is connected to the first manifold 241. The first inlet 221 is connected to the starting point of the first process 211 through the first manifold 241.

The starting point of the fourth process 214 is connected to the second manifold 242, and the ending point of the fourth process 214 is connected to the first manifold 241. The ending point of the fourth process 214 is connected to the starting point of the second process 212 through the second manifold 242. The starting point of the third process 213 and the ending point of the fourth process 214 are not connected within the first manifold 241. The first outlet 231 is located on the first manifold 241 at a position corresponding to the ending point of the fourth process 214.

In this manner, when the refrigerant flows into the flow channel 210 through the first inlet 221, all four processes of the heat exchanger 200 perform heat exchange; when the refrigerant flows into the flow channel 210 through the second inlet 222, the third process 213 and the fourth process 214 of the heat exchanger 200 perform heat exchange.
[0026] In some embodiments, the heat exchanger 200 further includes a receiver 250, which is connected to the end point of the third process 213 via a second manifold 242. The receiver 250 is used to store excess refrigerant. In some embodiments, the receiver has an opening sealed by a sealing block 251. In this manner, the sealing block 251 is used to seal the opening, and when the sealing block 251 is opened, refrigerant can be discharged from the receiver 250.
[0027] In some embodiments, such as Figure 3 As shown, the second inlet 222 is located in the liquid receiver 250, and the second inlet 222 is connected to the end point of the third process 213 through the liquid receiver 250 and the second manifold 242. In this manner, when the refrigerant flows into the flow channel 210 through the first inlet 221, all four processes of the heat exchanger 200 perform heat exchange; when the refrigerant flows into the flow channel 210 through the second inlet 222, the fourth process 214 of the heat exchanger 200 performs heat exchange.
[0028] In some embodiments, such as Figure 4 As shown, the second inlet 222 is located in the liquid receiver 250 and on the sealing block 251. The second opening 222 is connected to the end point of the third process 213 through the liquid receiver 250 and the second manifold 242. In this manner, when the refrigerant flows into the flow channel 210 through the first inlet 221, all four processes of the heat exchanger 200 perform heat exchange; when the refrigerant flows into the flow channel 210 through the second inlet 222, the fourth process 214 of the heat exchanger 200 performs heat exchange.

The control valves include a first control valve and a second control valve. The outlet of the compressor is connected to the inlet of the first heat exchanger via the first control valve. The outlet of the compressor is connected to the inlet of the second heat exchanger via the second control valve. The outlets of the first and second heat exchangers merge and are then connected to the inlet of the battery cooler and the inlet of the evaporator via a third control valve and a fourth control valve, respectively. The outlet of the battery cooler is connected to the inlet of the compressor, and the outlet of the evaporator is connected to the inlet of the compressor. When the temperature of the refrigerant at the outlet of the compressor is greater than the first preset threshold, the first control valve is opened and the second control valve is opened, and the refrigerant flows into the first heat exchanger and the second heat exchanger at the same time. When the temperature of the refrigerant at the outlet of the compressor is within a first preset range, the first control valve is opened and the second control valve is closed, and the refrigerant flows into the first heat exchanger. When the temperature of the refrigerant at the compressor outlet is within the second preset range, the first control valve is closed and the second control valve is opened, allowing the refrigerant to flow into the second heat exchanger.
10. A vehicle, characterized in that, Includes the thermal management system described in any one of claims 1-9.
