Description

Technical Field

[0001] The present disclosure relates to a cooling system for cooling a vehicle component. The cooling system comprises a main cooling circuit connected to the vehicle component and a temporary cooling circuit connected to the vehicle component. The cooling system is configured to operate with the aid of the main cooling circuit in a normal operating state. The present disclosure also relates to a method for operating a cooling system for cooling a vehicle component and a vehicle comprising a cooling system for cooling a vehicle component. Background Art

[0002] The heating and cooling systems of vehicles are commonly used in vehicle applications to control the temperature range of different key vehicle components, such as vehicle control units, battery units, power electronic units and other types of vehicle units or components that are part of the vehicle construction. For example, in new energy vehicles (such as hybrid or electric vehicles, including battery electric vehicles, fuel cell electric vehicles and plug-in hybrid electric vehicles), high-voltage battery components used to provide energy to electric motors and power electronic components and control units need to be temperature controlled. Under normal conditions, temperature control may depend on, for example, the driving conditions of the vehicle, the ambient temperature and the types of components used in the vehicle system. The thermal management of the vehicle is constructed to cool or heat the corresponding vehicle system.

[0003] Compared to the systems used in traditional vehicles with internal combustion engines, the thermal management systems for new energy vehicles need to be redesigned. These systems are often complex in design and construction, involving a large number of components that take up space in the vehicle and increase the weight of the vehicle construction. This leads to component installation problems and weight issues, and in addition, the thermal management systems are often expensive and inflexible in construction.

[0004] In new energy vehicle applications, there is a high demand for cooling key vehicle components, and cooling circuits with heat transfer fluids are operated to control the temperature levels of vehicle components. An example of a key vehicle component that requires temperature control is the central processing unit (CPU). The exact temperature of the CPU is difficult to predict, and the functionality of the CPU does not decrease with increasing temperature. When overheated, the CPU permanently fails during operation at the high cost and risk of functional loss.

[0005] When the temperature of the CPU or other critical vehicle components increases, it is important to cool the CPU or vehicle components to a suitable operating temperature. If a cooling circuit that is controlling the temperature of a vehicle component fails, there is a high risk of overheating the vehicle component.

[0006] A malfunction of a cooling system may be, for example, a leak or blockage of a cooling circuit, resulting in inefficient cooling of critical vehicle components. However, in currently used systems, it is difficult to detect a leak or blockage of a cooling circuit and to act upon it quickly. Therefore, there is a need for an improved cooling system, wherein the system is simple in design and construction, has fewer components than currently used systems, and wherein the system is also designed to be able to act quickly on faulty cooling, so that effective cooling of critical vehicle components can be established even when a cooling circuit operating under normal conditions fails. Summary of the invention

[0007] The object of the present disclosure is to provide a cooling system for cooling a vehicle component, a method for operating a cooling system for cooling a vehicle component, and a vehicle comprising a cooling system for cooling a vehicle component, wherein the aforementioned problems are avoided.

[0038] Various aspects of the present disclosure will be described below in conjunction with the accompanying drawings to illustrate rather than limit the present disclosure, wherein like reference numerals represent like elements, and variations of the aspects are not limited to the specifically shown embodiments but may be applied to other variations of the present disclosure.

[0039] Figure 1 The system layout of a cooling system S for cooling a vehicle component 1 is schematically shown. The cooling system S comprises a main cooling circuit 2 connected to the vehicle component 1 and a temporary cooling circuit 3 connected to the vehicle component 1. Figure 3 , a perspective view of a cooling system S is schematically shown.

[0040] The vehicle component 1 may be any critical component or system of the vehicle that requires cooling during operation. Examples of vehicle components 1 that require cooling are vehicle control units, which include central processing units (CPUs), battery units, power electronics units, and other types of vehicle units or components that are part of the vehicle configuration. A specific example of a critical vehicle component that requires temperature control is a CPU, where the exact temperature of the CPU is difficult to predict. The functionality of the CPU does not decrease with increasing temperature, and when overheated, the CPU permanently fails during operation at a high cost and risk of functional loss.

[0041] For example, Figure 1 and Figure 3 As shown, the cooling system S comprises a valve unit 4. The valve unit 4 connects the main cooling circuit 2 to the vehicle component 1. The valve unit 4 also connects the temporary cooling circuit 3 to the vehicle component 1.

[0042] The primary cooling circuit 2 may have any suitable configuration for cooling the vehicle component 1 and may be configured as follows: Figure 1 and Figure 3 An exemplary embodiment of a system configuration is schematically shown in FIG. Figure 1 In the illustrated embodiment, the main cooling circuit 2 includes a circulation pump 2a for circulating a heat transfer fluid F, a heat exchanger 2b for cooling the heat transfer fluid F, and an expansion bottle 2c. The circulation pump 2a may have any suitable configuration for conveying the heat transfer fluid F. The heat exchanger 2b may be configured as a radiator, or alternatively may be configured as a heat exchanger connected to a separate cooling circuit or refrigerant circuit not shown. The expansion bottle 2c may have any suitable configuration that allows the heat transfer fluid F to expand without causing failure of the cooling system S, and the expansion bottle 2c prevents the cooling system S from becoming over-pressurized as the heat transfer fluid F heats up and expands. However, it should be understood that the main cooling circuit 2 may include any suitable components required to cool the vehicle components 1, depending on the design and construction of the vehicle, and the components shown merely illustrate a possible system layout. Figure 3In the embodiment shown, components of the main cooling circuit 2 are omitted, which are indicated by the dashed portion of the cooling circuit.

[0043] Under normal operating conditions of the vehicle, the cooling system S is in a normal operating state S by means of the main cooling circuit 2 for cooling the vehicle component 1. N The following operations, such as Figure 2a and Figure 4a As shown. In normal operation state S N In the normal operating state S N Under the condition that the heat transfer fluid F is allowed to circulate from the main cooling circuit 2 to the vehicle component 1 via the valve unit 4. The components of the main cooling circuit 2 are fluidly connected with conduits, pipes or other suitable connection means, which are used to convey the heat transfer fluid F in the main cooling circuit, convey the heat transfer fluid F from the main cooling circuit 2 to the vehicle component 1 via the valve unit 4, and convey the heat transfer fluid F from the vehicle component 1 to the main cooling circuit 2 via the valve unit 4. The main cooling circuit 2 thus has the function of cooling the vehicle component 1 during normal operation and driving conditions of the vehicle, as will be further described below.

[0044] The cooling system S is also configured to operate in a redundant operating state S by means of the temporary cooling circuit 3 in the event of a failure of the main cooling circuit 2. R In Figure 2b and Figure 4b The redundant operating state S is schematically shown in R , and the cooling system S is configured to be enabled for use in a redundant operating state S R The temporary cooling circuit 3 cools the vehicle component 1 in a redundant operating state S. R The temporary cooling circuit 3 is connected to the vehicle component 1 via the valve unit 4 and is in the redundant operating state S R When connected to the vehicle component 1 via the valve unit 4 , the heat transfer fluid F is allowed to circulate from the temporary cooling circuit 3 via the valve unit 4 to the vehicle component 1 .

[0045] Examples of failures of the primary cooling circuit 2 are leakage of the heat transfer fluid F from the primary cooling circuit 2 or blockage of the heat transfer fluid F in the primary cooling circuit 2. For example, leakage of the heat transfer fluid F from the primary cooling circuit 2 may occur if any conduit leaks, if any connection between a component and a conduit leaks, or if any component leaks. Leakage may occur if a conduit, connection or component bulges or breaks, or if a seal is damaged. Blockage of the heat transfer fluid F in the primary cooling circuit 2 may occur if the flow of the heat transfer fluid F cannot be delivered (which may be caused by a faulty component), or if an object or contaminant blocks the flow path. Blockage of the heat transfer fluid F in the primary cooling circuit 2 may also occur if the power supply to the component does not function properly, such as in the event of a power outage or a blown fuse. A specific example of a blockage is if the power supply to the circulation pump 2a is blocked, which in turn hinders the delivery of the heat transfer fluid F in the primary cooling circuit 2.

[0046] The cooling system S comprises at least one sensor 7, such as Figure 1 The sensor 7 is configured to detect a fault in the primary cooling circuit 2. The at least one sensor 7 is suitably a pressure sensor, a temperature sensor and / or a flow sensor connected to the primary cooling circuit 2, and the at least one sensor 7 is arranged to detect a leak or a blockage in the primary cooling circuit 2.

[0047] For example Figure 2b and Figure 4b As shown, the temporary cooling circuit 3 comprises a storage unit 8 configured to contain a volume of heat transfer fluid F. The volume of heat transfer fluid F is arranged to be stored in the redundant operating state S R The storage unit 8 is used as a cooling volume through which the heat transfer fluid F flows. The storage unit 8 comprises a flow inlet 8a and a flow outlet 8b. The heat transfer fluid F is in a redundant operating state S R , which flows into the storage unit 8 via the flow inlet 8a and flows out of the storage unit 8 via the flow outlet 8b. If the storage unit 8 is placed at an appropriate location in the vehicle, the temperature of the heat transfer fluid F in the storage unit 8 can be maintained at the ambient temperature, for example, and for a certain period of time, the volume of the heat transfer fluid F in the storage unit 8 acts as a thermal buffer until a specific cooling temperature of the vehicle component 1 is reached. The storage unit 8 can be cooled with a suitable cooling device. If the main cooling circuit 2 fails, when the temporary cooling circuit 3 is in the redundant operating state S RThe user of the vehicle has enough time to take action when the vehicle is activated. The cooling system S is therefore appropriately designed to have a certain volume of heat transfer fluid F in the storage unit 8 and a certain flow rate of the heat transfer fluid F in the temporary cooling circuit 3 to allow the user to take action and drive the vehicle to a safe position. As a non-limiting example, the actual reaction time of the user may be at least 2 minutes to 4 minutes, allowing the user to safely stop the vehicle in most driving scenarios.

[0048] The temporary cooling circuit 3 also includes a pump 9 which is used in the redundant operating state S R The heat transfer fluid F in the temporary cooling circuit 3 is circulated to the vehicle component 1 and through the storage unit 8. The cooling system S is configured to actuate the pump 9 when a failure of the main cooling circuit 2 is detected, which will be further described below. The pump 9 can have any suitable configuration for conveying the heat transfer fluid F, and the flow rate of the heat transfer fluid F from the pump can be determined based on, for example, the volume of the heat transfer fluid in the storage unit 8, the temperature of the heat transfer fluid in the storage unit 8, and the temperature of the vehicle component 1. Depending on the design of the cooling system S, the pump 9 can be arranged in the flow path of the temporary cooling circuit 3 and before or after the storage unit 8. Figure 3 As shown in the illustrated embodiment, the pump 9 can also be arranged connected to the storage unit 8. In an alternative, not shown, embodiment, the pump 9 can be arranged within the storage unit 8 or structurally integrated with the storage unit 8.

[0049] In the redundant operation state S R The temporary cooling circuit 3 is connected to the vehicle component 1 via the valve unit 4, such as Figure 2b and Figure 4b As shown. In the redundant operation state S R Under the condition that the heat transfer fluid F is allowed to circulate from the temporary cooling circuit 3 to the vehicle component 1 via the valve unit 4. The components of the temporary cooling circuit 3 (such as the storage unit 8 and the pump 9) are fluidly connected with a conduit, a pipe or other suitable connection device, which is used to transport the heat transfer fluid F in the temporary cooling circuit 3, transport the heat transfer fluid F from the temporary cooling circuit 3 to the vehicle component 1 via the valve unit 4, and transport the heat transfer fluid F from the vehicle component 1 to the temporary cooling circuit 3 via the valve unit 4.

[0050] The cooling system S suitably also comprises a control unit, not shown, which governs and controls the operation of the components and circuits of the cooling system S, such as the pump 9 and the valve 4 .

[0051] The valve unit 4 is designed to be suitable for N The temporary cooling circuit 3 is disconnected from the fluid communication with the vehicle component 1 and in the redundant operating state S RThe fluid connection between the main cooling circuit 2 and the vehicle component 1 is disconnected. When the main cooling circuit 2 is in the normal operating state S N When the temporary cooling circuit 3 is connected to the vehicle component 1 and is in fluid communication with the vehicle component 1, the temporary cooling circuit 3 is prevented from being in fluid communication with the vehicle component 1 by the valve unit 4. In this way, the main cooling circuit 2 and the vehicle component 1 are formed in the normal operating state S N When the temporary cooling circuit 3 is in the redundant operating state S R When the temporary cooling circuit 3 and the vehicle component 1 are connected to the vehicle component 1 and are in fluid communication with the vehicle component 1, the main cooling circuit 2 is prevented from being in fluid communication with the vehicle component 1 by the valve unit 4. In this way, the temporary cooling circuit 3 and the vehicle component 1 are formed in a redundant operating state S R The closed cooling circuit is separated from the main cooling circuit 2. With this valve configuration, in the normal operating state S N The lower main cooling circuit 2 is completely separated from the temporary cooling circuit 3 by the valve unit 4 and is in the redundant operating state S R The lower temporary cooling circuit 3 is completely separated from the main cooling circuit 2 by a valve unit 4 .

[0052] For example Figure 1 and Figure 3 As shown, the cooling system S includes a further cooling circuit 10 connected to the vehicle component 1 and the valve unit 4. Each of the main cooling circuit 2 and the temporary cooling circuit 3 can be connected to the vehicle component 1 via the valve unit 4 and the further cooling circuit 10. Figure 2a to Figure 2b , Figure 4a to Figure 4b and Figure 6a to Figure 6b As shown by the arrow in FIG. 1 , the other cooling circuit 10 is arranged to be in the normal operating state S N and redundant operation status S R The heat transfer fluid F is delivered from the valve unit 4 to the vehicle component 1 and from the vehicle component 1 to the valve unit 4. As can be understood from the figure, the other cooling circuit 10 is formed by a conduit, a pipe or other suitable connection device, which is used to deliver the heat transfer fluid F from the valve unit 4 to the vehicle component 1 and to deliver the heat transfer fluid F from the vehicle component 1 to the valve unit 4. The vehicle component 1 appropriately includes a flow channel or similar arrangement, not shown, which is used to cool the vehicle component 1 with the heat transfer fluid F. In the illustrated embodiment, the vehicle component 1 includes an inlet port 1a and an outlet port 1b connected to the other cooling circuit 10, and the flow channel or similar arrangement of the vehicle component 1 is connected to the inlet port 1a and the outlet port 1b so that the heat transfer fluid F can flow through the vehicle component 1.

[0053] The valve unit 4 may have any suitable configuration for controlling the flow of the heat transfer fluid F to and from the vehicle component 1. Figure 1 , Figure 3 and Figure 4a to Figure 4b In the illustrated embodiment, the valve unit 4 comprises a first inflow port 5a and a first outflow port 6a connected to the vehicle component 1. The valve unit 4 further comprises a second inflow port 5b and a second outflow port 6b connected to the main cooling circuit 2, and a third inflow port 5c and a third outflow port 6c connected to the temporary cooling circuit 3.

[0054] In one embodiment, the valve unit 4 includes a valve body 4a, such as Figure 5a to Figure 5b and Figure 6a to Figure 6b As shown. Figure 6a As shown, the valve body 4a is in the normal operating state S N , arranged in the first valve position P V1 In the first valve position P V1 , the second inlet port 5b is in fluid communication with the first outlet port 6a, and the second outlet port 6b is in fluid communication with the first inlet port 5a. Figure 2a and Figure 4a As shown by the arrow in the figure, the first valve position P V1 The heat transfer fluid is allowed to circulate from the main cooling circuit 2 to the vehicle component 1 and from the vehicle component 1 to the main cooling circuit 2 via the valve unit 4. V1 The valve body 4a blocks fluid communication between the third inflow port 5c and the first outflow port 6a, and blocks fluid communication between the third outflow port 6c and the first inflow port 5a. In this way, flow from the temporary cooling circuit 3 to the vehicle component 1 is prevented.

[0055] like Figure 6b As shown, the valve body 4a is in the redundant operation state S R , arranged in the second valve position P V2 In the second valve position P V2 , the third inflow port 5c is in fluid communication with the first outflow port 6a, and the third outflow port 6c is in fluid communication with the first inflow port 5a. Figure 2b and Figure 4b As shown by the arrow in the figure, the second valve position P V2 The heat transfer fluid is allowed to circulate from the temporary cooling circuit 3 via the valve unit 4 to the vehicle component 1 and from the vehicle component 1 to the temporary cooling circuit 3. V2 The valve body 4a blocks fluid communication between the second inlet port 5b and the first outlet port 6a, and blocks fluid communication between the second outlet port 6b and the first inlet port 5a. In this way, flow from the main cooling circuit 2 to the vehicle component 1 is prevented.
