The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
A vehicle heat exchange cycle system 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 5 in conjunction with the embodiment.
As shown in fig. 1 to 5, the vehicle heat exchange circulation system 100 may include a battery pack heat dissipation loop 110, an electrical appliance heat dissipation loop 120, and a passenger compartment heating loop 130, where the battery pack heat dissipation loop 110 is connected with a battery pack 11, a battery pack radiator 12, and a heat exchanger 13, that is, the battery pack radiator 12, the heat exchanger 13, and the battery pack 11 may all be connected in the battery pack heat dissipation loop 110, the battery pack heat dissipation loop 110 may be a heat exchange pipe loop in which a heat exchange medium such as liquid (e.g., water) or gas (e.g., air) flows, when an ambient temperature of the battery pack 11 is higher than a proper working temperature of the battery pack 11, the battery pack radiator 12 cools the heat exchange medium in the battery pack heat dissipation loop 110, and then the cooled heat exchange medium passes through the battery pack 11 to dissipate heat of the battery pack 11, thereby achieving heat dissipation of the battery pack radiator 12 to the battery pack 11, the battery pack 11 is ensured to work at a proper working temperature, and the working reliability of the battery pack 11 is improved.
The electrical appliance radiator 22 and the electrical appliance 21 are connected in the electrical appliance radiating loop 120, that is, both the electrical appliance radiator 22 and the electrical appliance 21 can be connected in the electrical appliance radiating loop 120, the electrical appliance radiating loop 120 can be a heat exchange pipeline loop with heat exchange media such as liquid (for example, water) or gas (for example, air) flowing inside, when the environmental temperature of the electrical appliance 21 is higher than the proper working temperature of the electrical appliance 21, the electrical appliance radiator 22 cools the heat exchange media in the electrical appliance radiating loop 120, and then the cooled heat exchange media can radiate the electrical appliance 21 when passing through the electrical appliance 21, so that the heat radiation of the electrical appliance radiator 22 to the electrical appliance 21 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.

The electrical equipment 21, the battery pack 11, the battery pack radiator 12 and the electrical equipment radiator 22 may be arranged according to the space requirement of the vehicle, the electrical equipment 21 is electrical equipment in the vehicle, for example, the electrical equipment 21 may include components of a driving motor 212, a charger, a power distribution box 211, a DC-DC converter and the like of the vehicle for driving the vehicle to run, and heat dissipation pipelines between the components of the electrical equipment 21 may be connected in parallel and/or in series.
When the environment inside the passenger compartment is low, so that the passengers in the passenger compartment feel untimely, the heat exchange medium in the passenger compartment heating loop 130 can heat the passenger compartment, so that the temperature in the passenger compartment is increased, and the riding experience of the passengers is improved. The passenger compartment heating circuit 130 is selectively in communication with the heat exchanger 13. In other words, when there is no heating demand from the battery pack 11, the passenger compartment heating circuit 130 is not in communication with the heat exchanger 13, and only the passenger compartment is heated. When the ambient temperature of the battery pack 11 is lower than the proper working temperature and the battery pack 11 needs to be heated, the passenger compartment heating loop 130 is communicated with the heat exchanger 13, so that the heat exchange medium in the passenger compartment heating loop 130 heats the heat exchange medium in the battery pack heat dissipation loop 110 through the heat exchanger 13, and at the moment, the battery pack radiator 12 is in a stop working state, so that the heat exchange medium in the battery pack heat dissipation loop 110 can heat the battery pack 11.
According to the vehicle heat exchange cycle system 100 of the embodiment of the invention, the passenger compartment heating circuit 130 is selectively communicated with the heat exchanger 13, when the ambient temperature of the battery pack 11 is low, the passenger compartment heating circuit 130 can heat the passenger compartment and heat the battery pack 11 to a proper working temperature, so that a structure for separately heating the battery pack 11 is not needed, and the energy utilization rate is improved.
Specifically, as shown in fig. 1, 4 and 5, the passenger compartment heating circuit 130 includes a main heating passage 133, a first passage 131 and a second passage 132, the main heating passage 133 is connected with a heater 31 and a warm air core 32, when the environment inside the passenger compartment is low and the passengers in the passenger compartment feel uncomfortable, the heater 31 can heat the heat exchange medium flowing through the passenger compartment heating circuit 130, 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 be heated by the heat exchange medium and then blown to the passenger compartment of the vehicle, so as to increase the temperature in the passenger compartment and improve the riding experience of the passengers.
The main heating passage 133 is optionally connected in series with the first passage 131 or the second passage 132 to form the passenger compartment heating circuit 130, wherein the heat exchanger 13 is connected to the second passage 132, and when the main heating passage 133 is connected in series with the second passage 132, the heat exchange medium heated by the main heater 31 can heat the heat exchange medium in the battery pack heat dissipation circuit 110 through the heat exchanger 13, so that heat exchange is performed between the passenger compartment heating circuit 130 and the battery pack heat dissipation circuit 110.
Specifically, as shown in fig. 1, a first water pump 41 is connected to the electrical appliance heat dissipation circuit 120, a second water pump 42 is connected to the passenger compartment heating circuit 130, and a third water pump 43 is connected to the battery pack heat dissipation circuit 110. Therefore, the first water pump 41 can pump the heat exchange medium in the electrical appliance heat dissipation loop 120 dynamically to provide flowing power for the heat exchange medium in the electrical appliance heat dissipation loop 120 and the battery pack 11 heating loop, and the second water pump 42 can pump the heat exchange medium in the battery pack heat dissipation loop 110 dynamically to provide flowing power for the heat exchange medium in the battery pack heat dissipation loop 110. The third water pump 43 may power pump the heat exchange medium within the passenger compartment heating circuit 130 to provide flow power to the passenger compartment heating circuit 130 of the battery pack heat rejection circuit 110.
Specifically, as shown in fig. 1, a first overflow tank 51 is connected to the electrical appliance heat dissipation circuit 120, and a second overflow tank 52 is connected to the passenger compartment heating circuit 130. The first overflow tank 51 may temporarily store the surplus heat exchange medium when the heat exchange medium in the electric appliance heat dissipation circuit 120 is thermally expanded, and the second overflow tank 52 may temporarily store the surplus heat exchange medium when the heat exchange medium in the passenger compartment heating circuit 130 is thermally expanded.
In some specific embodiments, as shown in fig. 1, the heat exchange medium in the battery pack heat dissipation circuit 110 and the electrical appliance heat dissipation circuit 120 is liquid, the gas-liquid separation tank 14 is connected in the battery pack heat dissipation circuit 110, the electrical appliance heat dissipation circuit 120 is communicated with the gas-liquid separation tank 14, the gas-liquid separation tank 14 can mix gas in the heat dissipation liquid in the battery pack heat dissipation circuit 110 and the electrical appliance heat dissipation circuit 120, and the heat exchange liquid can be injected into the battery pack heat dissipation circuit 110 and the electrical appliance heat dissipation circuit 120 from the gas-liquid separation tank 14. Therefore, the battery pack heat dissipation loop 110 can not only meet the air overflow and water supplement effects, but also reduce the complexity of the whole vehicle heat exchange liquid filling process.
Specifically, as shown in fig. 1, the first overflow tank 51 of the consumer heat dissipation circuit 120 communicates with the gas-liquid separation tank 14. The first overflow tank 51 can thus more conveniently temporarily store the surplus heat exchange medium when the heat exchange medium fed from the gas-liquid separation tank 14 and flowing into the consumer heat dissipation circuit 120 expands due to heating.
Specifically, as shown in fig. 1, the vehicle heat exchange cycle system 100 further includes a three-way valve 6 and a two-position three-way valve 7, wherein three ports of the three-way valve 6 are respectively communicated with the second end of the main heating passage 133, the second end of the first passage 131 and the second end of the second passage 132, that is, the three-way valve 6 can communicate one ends of the main heating passage 133, the first passage 131 and the second passage 132.
An inlet of the two-position three-way valve 7 communicates with a first end of the main heating passage 133, and two outlets of the two-position three-way valve 7 communicate with a first end of the first passage 131 and a first end of the second passage 132, respectively. For example, as shown in fig. 1, the first outlet a of the two-position three-way valve 7 communicates with the first passage 131, and the second outlet b of the two-position three-way valve 7 communicates with the second passage 132.
When the main heating passage 133 only needs to heat the warm air core 32, the inlet of the two-position three-way valve 7 may be communicated with the first outlet a, and the inlet of the two-position three-way valve 7 may be disconnected from the second outlet b, at this time, the main heating passage 133 is communicated with the first passage 131, and the main heating passage 133 is disconnected from the second passage 132, the heat exchange medium in the passenger compartment heating circuit 130 does not flow through the heat exchanger 13, and at this time, the passenger compartment heating circuit 130 heats the warm air core 32 without heating the battery pack 11.
When the main heating path 133 needs to heat the battery pack 11, the inlet of the two-position three-way valve 7 may be communicated with the second outlet b, while the inlet of the two-position three-way valve 7 is disconnected from the first outlet a, at this time, the main heating path 133 is communicated with the second path 132, and the main heating path 133 is disconnected from the first path 131, and the heat exchange medium in the passenger compartment heating circuit 130 flows through the heat exchanger 13, at this time, the passenger compartment heating circuit 130 may heat the warm air core 32 and the battery pack 11 at the same time.
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. The two-position three-way valve 7 can be a two-position three-way electromagnetic valve to automatically control the selective opening and closing of the first outlet a and the second outlet b through a computer.
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 130, 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 33 is further connected to the passenger compartment heating circuit 130, and the condenser 33 can absorb heat generated by the electrical equipment 21 and/or the battery pack 11 during operation and heat the passenger compartment heating circuit 130 by using the heat. 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 33 through the passenger compartment heating circuit 130, so that hot air can be blown to the passenger compartment.
More specifically, as shown in fig. 1, the refrigerant passage of the condenser 33 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 dissipating medium in the battery pack heat dissipating circuit 110, the refrigerant of the battery pack radiator 12 flows to the condenser 33 through the refrigerant passage to exchange heat with the condenser 33, so that the condenser 33 absorbs heat of the battery pack radiator 12, and the condenser 33 can absorb heat generated when the battery pack 11 is operated.
