An electrical appliance heat dissipation loop 120 used for dissipating heat of an electrical appliance 21 is arranged between an electrical appliance heat sink 22 and the electrical appliance 21, that is, the electrical appliance heat sink 22 and the electrical appliance 21 can both be connected in the electrical appliance heat dissipation loop 120, the electrical appliance heat dissipation loop 120 can be a heat exchange pipeline loop in which a liquid (such as water) or a gas (such as air) and other heat exchange media flow, when the temperature of the electrical appliance 21 is higher than the proper working temperature of the electrical appliance 21, the electrical appliance heat sink 22 cools the heat exchange media in the electrical appliance heat dissipation loop 120, and then the cooled heat exchange media can dissipate heat of the electrical appliance 21 when passing through the electrical appliance 21, so that heat dissipation of the electrical appliance 21 by the electrical appliance heat sink 22 is realized, the electrical appliance 21 is ensured to work at the proper working temperature, and the working reliability of the electrical appliance 21 is improved.

When the internal environment of the passenger cabin is low, and thus the passengers in the passenger cabin feel untimely, the third water pump 63 can drive the heat exchange medium in the passenger cabin heating loop 150 to flow, the heater 31 can heat the heat exchange medium in the passenger cabin heating loop 150 flowing through, the heated heat exchange medium can be further heated by the warm air core 32, and the air in the warm air core 32 can blow hot air into the passenger cabin of the vehicle after being heated by the heat exchange medium, so that the temperature in the passenger cabin is increased, and the riding experience of the passengers is improved.
The battery pack 11 may optionally be in communication with a heat exchanger 33 to form a battery pack heating circuit 140. In other words, when the battery pack 11 has no heating demand, the battery pack 11 does not communicate with the heat exchanger 33. When the temperature of the battery pack 11 is lower than the proper working temperature and the battery pack 11 needs to be heated, the battery pack 11 is communicated with the heat exchanger 33 to form a battery pack heating circuit 140, and then the heat exchange medium in the passenger compartment heating circuit 150 heats the heat exchange medium in the battery pack heating circuit 140 through the heat exchanger 33, so that the heat exchange medium in the battery pack heating circuit 140 can heat the battery pack 11.
According to the vehicle heat exchange cycle system 100 of the embodiment of the invention, the battery pack 11 is selectively communicated with the heat exchanger 33, when the temperature of the battery pack 11 is low, the passenger compartment heating circuit 150 can heat the battery pack 11 to a proper working temperature through the heat exchanger 33, so that a structure for separately heating the battery pack 11 is not needed, and the energy utilization rate is improved.

The battery pack low-temperature heat dissipation circuit 130 may be a heat exchange pipe circuit in which a heat exchange medium such as liquid (e.g., water) or gas (e.g., air) flows.
When the temperature of the battery pack 11 is slightly higher than the proper working temperature of the battery pack 11 (for example, when the temperature is higher than the proper working temperature of the battery pack 11 by less than 10 ℃), the electrical appliance radiator 22 cools the electrical appliance 21 through the heat exchange medium of the electrical appliance heat dissipation loop 120, and simultaneously cools the heat exchange medium in the battery pack low-temperature heat dissipation loop 130, so that the cooled heat exchange medium can dissipate heat at low temperature of the battery pack 11 when passing through the battery pack 11, thereby realizing heat dissipation of the battery pack 11 by the battery pack radiator 12, ensuring that the battery pack 11 works at the proper working temperature, and improving the working reliability of the battery pack 11. At the moment, the battery pack radiator 12 does not need to be additionally started to radiate the battery pack 11, so that the energy consumption is saved.

As shown in fig. 4, when low-temperature heat dissipation needs to be performed on the battery pack 11, the inlet of the first two-position three-way valve 51 is communicated with the first outlet a and disconnected from the second outlet b, and the inlet of the second two-position three-way valve 52 is communicated with the second outlet b and disconnected from the first outlet a, so as to form a battery pack low-temperature heat dissipation loop 130.
As shown in fig. 2, when the high-temperature heat dissipation of the battery pack 11 is required, the inlet of the first two-position three-way valve 51 is connected to the first outlet a and disconnected from the second outlet b, and the inlet of the second two-position three-way valve 52 is connected to the first outlet a and disconnected from the second outlet b, so as to form the high-temperature heat dissipation loop 110 of the battery pack.
As shown in fig. 5, when the battery pack 11 needs to be heated, the inlet of the first two-position three-way valve 51 is connected to the second outlet b and disconnected from the first outlet a, and at this time, the heat exchange medium does not flow through the second two-position three-way valve 52 and completely flows through the first two-position three-way valve 51, so as to form the battery pack heating circuit 140.
It should be noted that the first end of each passage is the corresponding upper end in fig. 1-5, and the second end of each passage is the corresponding lower end in fig. 1-5, and "up" and "down" in this description are only schematic illustrations for convenience of description in conjunction with the drawings, and do not necessarily indicate the actual direction of the corresponding passage. Each two-position three-way valve can be a two-position three-way electromagnetic valve so as to automatically control the selective opening and closing of the first outlet a and the second outlet b through a computer.
Specifically, as shown in fig. 1 to 5, a first water pump 61 is connected to the second passage 102, a second water pump 62 is connected to the passenger compartment heating circuit 150, and a third water pump 63 is connected to the third passage 103. Therefore, the first water pump 61 can pump the heat exchange medium in the second passage 102 to provide flowing power for the heat exchange medium in the electrical appliance heat dissipation circuit 120 and the battery pack 11 low-temperature heating circuit, the second water pump 62 can pump the heat exchange medium in the passenger compartment heating circuit 150 to provide flowing power for the heat exchange medium in the passenger compartment heating circuit 150, and the third water pump 63 can pump the heat exchange medium in the third passage 103 to provide flowing power for the heat exchange medium in the battery pack low-temperature heat dissipation circuit 130, the battery pack high-temperature heat dissipation circuit 110 and the battery pack heating circuit 140.
Specifically, as shown in fig. 1, a first overflow tank 71 is connected to the first passage 101, and the first overflow tank 71 may temporarily store the surplus heat exchange medium when the heat exchange medium in the first passage 101 expands due to heat. The second overflow tank 72 is connected to the passenger compartment heating circuit 150, and the second overflow tank 72 may temporarily store the surplus heat exchange medium when the heat exchange medium in the passenger compartment heating circuit 150 is expanded by heat.
More specifically, the warm air core 32 includes an air duct and a blower, and after the air in the air duct is heated by the passenger compartment heating circuit 150, the blower can blow the heated air in the air duct into the passenger compartment, so that the warm air core 32 blows hot air to the passenger compartment.
Specifically, as shown in fig. 1, a condenser 34 is further connected in the passenger compartment heating circuit 150, and the condenser 34 can absorb heat generated by the electrical equipment 21 or/and the battery pack 11 during operation and use the heat to heat the passenger compartment heating circuit 150. Therefore, when the temperature in the passenger compartment is at a high value and only needs to be raised to a low temperature, the heater 31 does not need to be turned on, and the warm air core 32 can be heated by the heat absorbed by the condenser 34 through the passenger compartment heating circuit 150, so that hot air can be blown to the passenger compartment.
More specifically, as shown in fig. 1, the refrigerant passage of the condenser 34 communicates with the refrigerant passage of the battery pack radiator 12, which is indicated by a broken line in fig. 1. Thus, after absorbing heat of the heat dissipation medium in the high-temperature heat dissipation circuit 110, the refrigerant of the battery pack radiator 12 flows to the condenser 34 through the refrigerant passage to exchange heat with the condenser 34, so that the condenser 34 absorbs heat of the battery pack radiator 12, and the condenser 34 can absorb heat generated by the battery pack 11 during operation.
Specifically, as shown in fig. 1 and 4, the solenoid valve 8 is connected to the first passage 101, and the computer can automatically control the solenoid valve 8 to switch the solenoid valve 8 between the connection state and the disconnection state. When the electrical appliance 21 needs to be cooled, the electromagnetic valve 8 is in a connected state to ensure the connection of the electrical appliance cooling loop 120.
When the ambient temperature is low, the passenger compartment has a heating requirement, and the battery pack 11 and the driving motor 212 have a heat dissipation requirement, the electromagnetic valve 8 can be switched to an off state, at this time, the electric appliance heat dissipation loop 120 is disconnected, the second path 102, the third path 103 and the fourth path 104 are connected into a loop, so that the electric appliance 21 and the battery pack 11 commonly dissipate heat through the battery pack radiator 12, the refrigerant of the battery pack radiator 12 absorbs heat from the electric appliance 21 and the battery pack 11 simultaneously, so that the condenser 34 can absorb more heat, the heating effect of the condenser 34 on the warm air core 32 is improved, and the heating effect of the warm air core 32 on the passenger compartment is further improved.
