Detailed Description

Exemplary embodiments of the present disclosure are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 shows a block diagram of a vehicle thermal management system for thermally managing a first target object 1 and a second target object 2 in a vehicle according to an embodiment of the present disclosure. As shown in fig. 1, the vehicle heat management system includes a radiator 3, an air conditioning system 4, a first heat exchanger 5, a second heat exchanger 6, a first three-way valve 7, a second three-way valve 8, a first water pump 9, and a second water pump 10.

The radiator 3, the first interface of the first three-way valve 7, the second interface of the first three-way valve 7, the first water pump 9, the first interface of the second three-way valve 8 and the second interface of the second three-way valve 8 are sequentially connected through a first pipeline to form a first cooling loop flowing through the first target object 1;

The first channel of the first heat exchanger 5, the second water pump 10 and the first channel of the second heat exchanger 6 are sequentially connected through a second pipeline to form a second cooling loop flowing through the second target object 2, and the second channel of the first heat exchanger 5 is connected with the air conditioning system 4;

The second channel of the second heat exchanger 6, the first water pump 9, the first interface of the second three-way valve 8, the third interface of the second three-way valve 8, the first interface of the first three-way valve 7 and the third interface of the first three-way valve 7 are sequentially connected through a third pipeline to form a third cooling loop flowing through the first target object 1.

As shown in fig. 1, the air conditioning system 4 may include a compressor 4a, a condenser 4b, an expansion valve 4c, a fan 4d, and the like, and an inlet of the first passage of the first heat exchanger 5 may be connected to the expansion valve 4c, and an outlet thereof may be connected to the compressor 4 a.

The disclosed embodiments relate to a first heat exchanger 5 and a second heat exchanger 6, each heat exchanger has two channels for medium circulation, one of the channels is used for heat medium circulation, and the other channel is used for cold medium circulation, so that when cold and hot mediums flow through the heat exchangers, the cold medium can exchange heat with the heat medium, thereby taking away heat energy emitted by a target object and realizing heat dissipation of the target object. The type of heat exchanger may be, for example, a tube heat exchanger, a plate heat exchanger, a jacket heat exchanger, etc., which is not limited by the present embodiment. Taking a tubular heat exchanger as an example, the two channels of the heat exchanger may be a tube side and a shell side.

Since the first channel of the first heat exchanger 5 is connected to the second target object 2, and the second channel of the first heat exchanger 5 is connected to the air conditioning system 4, the first channel of the first heat exchanger 5 is a channel through which a heating medium flows, and the second channel of the first heat exchanger 5 is a channel through which a cooling medium flows.

The first channel (and the second channel) of the second heat exchanger 6 is not fixed to be a channel through which a heating medium flows or a channel through which a cooling medium flows. In different cases, the same channel may be used as a channel through which the heating medium flows or as a channel through which the cooling medium flows. In any case, the second heat exchanger 6 enables heat exchange between the second cooling circuit and the third cooling circuit, achieving the mutual association of the two cooling circuits.

In the embodiment of the disclosure, by arranging the second heat exchanger 6, the first three-way valve 7 and the second three-way valve 8 and changing the flow paths of the first three-way valve 7 and the second three-way valve 8, not only the first cooling circuit and the second cooling circuit which are independent of each other, but also the second cooling circuit and the third cooling circuit which are related to each other can be formed, so that the first target object 1 and the second target object 2 of the vehicle can be independently radiated, and the first target object 1 and the second target object 2 of the vehicle can be jointly radiated, thereby improving the thermal management efficiency of the vehicle.

In embodiments of the present disclosure, the thermal management system may include a plurality of three-way connectors 11 to facilitate connection between the components. For example, the radiator 3, the first three-way valve 7 and the second three-way valve 8 may be connected by a three-way joint 11. For example, the second port of the first three-way valve 7, the second passage of the second heat exchanger 6 and the first water pump 9 may be connected by a three-way joint 11. Specific connection modes may refer to the connection modes shown in fig. 1, and this is not specifically described in the embodiments of the present disclosure.

In the embodiment of the present disclosure, the cooling type of the first target object 1 and the second target object 2 is a liquid cooling type, and thus, the thermal management system may further include a first reservoir 12 (e.g., a kettle) that provides a heat exchange medium for the first cooling circuit or the third cooling circuit, and a second reservoir 13 (e.g., a kettle) that provides a heat exchange medium for the second cooling circuit. Specific connection modes may refer to the connection modes shown in fig. 1, and this is not specifically described in the embodiments of the present disclosure.

In some embodiments, as shown in fig. 1, the thermal management system further comprises a first heater 14 and a second heater 15;

The first heater 14 is arranged between the third interface of the second three-way valve 8 and the first interface of the first three-way valve 7;

The second heater 15 is disposed between the first passage of the second heat exchanger 6 and the first passage of the first heat exchanger 5.

In this embodiment, the second heater 15, the first passage of the first heat exchanger 5, the second water pump 10, and the first passage of the second heat exchanger 6 are sequentially connected to form a second heating circuit flowing through the second target object 2.

By communicating the first port and the third port of the second three-way valve 8, the first cooling circuit may be replaced with the first heating circuit, or the third cooling circuit may be replaced with the third heating circuit. Wherein the first heating circuit and the second heating circuit are mutually independent, and the third heating circuit is mutually related with the second heating circuit through the second heat exchanger 6.

Specifically, the first port and the second port of the first three-way valve 7 are communicated, so that a first heating circuit formed by sequentially connecting the first heater 14, the first port of the first three-way valve 7, the second port of the first three-way valve 7, the water pump, the first port of the second three-way valve 8, and the third port of the second three-way valve 8, and flowing through the first target object 1 can be formed. Or the first interface of the first three-way valve 7 is communicated with the third interface, so that a third heating loop formed by sequentially connecting the first heater 14, the first interface of the first three-way valve 7, the third interface of the first three-way valve 7, the second channel of the second heat exchanger 6, the first water pump 9, the first interface of the second three-way valve 8 and the third interface of the second three-way valve 8 and flowing through the first target object 1 can be formed.

It can be seen that in this embodiment, by providing the first heater 14 and the second heater 15, when there is a heating demand for the first target object 1 and the second target object 2, the first target object 1 and the second target object 2 can be heated. Accordingly, by changing the flow paths of the first three-way valve 7 and the second three-way valve 8, not only the first heating circuit and the second heating circuit which are independent of each other but also the second heating circuit and the third heating circuit which are related to each other can be formed, so that not only the first target object 1 and the second target object 2 of the vehicle can be independently heated, but also the first target object 1 and the second target object 2 of the vehicle can be jointly heated, and thus the vehicle thermal management efficiency can be improved.

The first heater 14 and the second heater 15 may be, for example, positive temperature coefficient (Positive Temperature Coefficient, PTC) heaters.

Alternatively, the heating capacity of the first heater 14 is smaller than that of the second heater 15.

By differently setting the heating capacity of the first heater 14 and the heating capacity of the second heater 15, the heating capacities of the first heater 14 and the second heater 15 can be rationally utilized according to specific heating requirements and different environmental conditions, thereby further improving the thermal management efficiency of the vehicle.

In some embodiments, as shown in fig. 1, the thermal management system further comprises a first temperature sensor 16 and a second temperature sensor 17;

the first temperature sensor 16 is provided between the first water pump 9 and the first target object 1;

The second temperature sensor 17 is provided between the second water pump 10 and the second target object 2.

In this embodiment, in order to facilitate the control of the thermal management system, the thermal management system may further implement the temperature detection of each cooling circuit (or heating circuit) by providing the first temperature sensor 16 and the second temperature sensor 17, thereby adjusting the flow paths of the first three-way valve 7 and the second three-way valve 8, thereby contributing to the improvement of the thermal management efficiency of the vehicle.

In some embodiments, the first target object 1 is an autopilot computer and the second target object 2 is a power battery.

For an autonomous vehicle, the cooling type of the autonomous computer (also called as autonomous hardware) is a liquid cooling type (such as a water cooling type), the autonomous vehicle may be a pure electric vehicle type or a hybrid vehicle type, and the cooling type of the power battery is a liquid cooling type (such as a water cooling type) are particularly important. The automatic driving computer water cooling system radiates heat outwards through a radiator 3 (also called as a low-temperature radiator 3), and the power battery water cooling system radiates heat through a first heat exchanger 5 and an air conditioning system 4. The first heater 14 may heat the water cooling system of the autopilot computer and the second heater 15 may heat the water cooling system of the power battery.

In summary, the embodiment of the disclosure can realize that the cooling circuit of the automatic driving computer and the cooling circuit of the power battery keep mutually independent heat dissipation or jointly dissipate heat, and can realize that the heating circuit of the automatic driving computer and the heating circuit of the power battery mutually independently heat or jointly heat, so that the thermal management efficiency of the vehicle can be improved.
