[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figure 1-2 As shown, an embodiment of this utility model provides an integrated domain controller cooling system, including an engine radiator 1, a controller radiator 2, and an expansion tank 4. The engine radiator 1 includes a radiator housing 11, and the controller radiator 2 is installed on the radiator housing 11. The controller radiator 2 can be connected to a domain controller 3 through a pipe. The expansion tank 4 has a first cavity 41 and a second cavity 42, which are separated by an insulation layer. The first cavity 41 is connected to the water inlet of the engine radiator 1 through a pipe, and the second cavity 42 is connected to the water inlet of the controller radiator 2 through a pipe.

[0039] By installing the controller radiator 2 onto the radiator housing 11 of the engine radiator 1, it is not necessary to set up the controller radiator 2 and the engine radiator 1 separately, reducing the number of structural components for installing the controller radiator 2 and achieving integration between the controller radiator 2 and the engine radiator 1. By using an expansion tank 4 with an integrated first cavity 41 and a second cavity 42, with the first cavity 41 and the second cavity 42 respectively connected to the corresponding radiator, it is not necessary to set up two expansion tanks 4 in the overall vehicle structure. While meeting the basic functions of the expansion tank 4, the number of expansion tanks 4 is reduced, making the overall vehicle structure layout compact, reducing the overall space occupied, reducing the weight of the vehicle, and lowering production costs.

[0040] When the engine is running, the coolant temperature in the engine radiator 1 rises, causing it to expand in volume. Excess coolant flows into the first chamber 41 of the expansion tank 4 through the pipes to prevent the cooling system from being damaged due to excessive pressure. When the coolant temperature in the engine radiator 1 drops, the coolant volume shrinks, and the first chamber 41 of the expansion tank 4 replenishes the engine radiator 1 with coolant to maintain the pressure balance of the cooling system and ensure its normal operation.

[0041] Similarly, when the domain controller 3 is running, the coolant temperature in the controller radiator 2 rises, causing it to expand in volume. Excess coolant will flow into the second chamber 42 through the pipes. When the amount of coolant in the controller radiator 2 is insufficient, the second chamber 42 of the expansion tank 4 will replenish the coolant to the controller radiator 2 through the pipes.

[0042] Since there is a difference in the operating temperature between the engine cooling system and the domain controller cooling system, the heat transfer efficiency between the first cavity 41 and the second cavity 42 of the expansion tank 4 can be effectively reduced by adopting a structure in which an insulation layer is set between the first cavity 41 and the second cavity 42. This effectively solves the problem of different temperature requirements between the engine cooling system and the domain controller cooling system, and ensures the normal operation of the engine cooling system and the domain controller cooling system.

[0043] For example, the insulation layer is a sealed cavity disposed between the first cavity 41 and the second cavity 42. In other embodiments, the insulation layer may also be an insulating filler material filled between the first cavity 41 and the second cavity 42.

[0044] Furthermore, the return port of the first chamber 41 is higher than the inlet of the engine radiator 1. This arrangement facilitates the replenishment of coolant from the first chamber 41 to the engine radiator 1 under the influence of gravity, while preventing coolant backflow.

[0045] Similarly, the return port of the second cavity 42 is higher than the inlet of the controller radiator 2, which can prevent coolant from flowing back.

[0046] Furthermore, the integrated domain controller cooling system also includes a liquid level detection unit and an alert unit. The liquid level detection unit is installed in the expansion tank 4 and is used to detect whether the liquid level in the expansion tank 4 has reached the preset liquid level. The alert unit is used to remind the user that the liquid level in the expansion tank 4 has reached the preset liquid level.

[0047] The integrated domain controller cooling system also includes a controller, a liquid level detection unit, and an alert unit, all of which are communicatively connected to the controller. The liquid level detection unit can detect the liquid level in the expansion tank 4. If the liquid level reaches a preset level, the liquid level detection unit transmits a signal to the controller, which then transmits the signal to the alert unit. The alert unit issues a warning signal, allowing personnel to replenish coolant in the expansion tank 4 in a timely manner. For example, the liquid level detection unit is a liquid level sensor.

[0048] Optionally, two liquid level detection units are provided, which are respectively arranged in the first cavity 41 and the second cavity 42.

[0049] Furthermore, liquid level marking lines are provided on the outer walls of the first cavity 41 and the second cavity 42. When the amount of coolant in the first cavity 41 and the second cavity 42 of the expansion tank 4 is insufficient, it can be detected by observing the liquid level marking lines or by the prompt signal issued by the reminder unit.

[0050] Furthermore, the expansion tank 4 is equipped with a pressure relief valve on its top. When the amount of coolant in the radiator is insufficient, the expansion tank 4 replenishes the coolant through a water pipe; when the amount of coolant is excessive, it can flow out through the overflow port of the pressure relief valve.

[0051] Furthermore, the engine radiator 1 also includes a fan 12 and a drive motor. The fan 12 is mounted on the radiator housing 11, and the drive motor is fixedly mounted on the radiator housing 11. The output end of the drive motor is fixedly connected to the fan 12, and the drive motor can drive the fan 12 to rotate.

[0052] like Figure 1 As shown, the fan 12 is located behind the radiator housing 11. The drive motor drives the fan 12 to rotate, which in turn causes airflow. The high-speed airflow can dissipate heat and cool the radiator housing 11 and the controller radiator 2. The fan 12 can dissipate heat and cool the radiator housing 11 and the controller radiator 2 simultaneously. That is, the radiator housing 11 and the controller radiator 2 share the fan 12, which reduces the number of fans 12 and thus reduces space occupation.

[0053] For example, fan 12 is a blower fan, and a fan guard is provided on the outside of fan 12. This configuration can improve safety and overall aesthetics. In other embodiments, fan 12 may also be a suction fan.

[0054] Furthermore, the engine radiator 1 also includes a temperature detection unit, which is electrically connected to the drive motor and is used to detect the temperature of the radiator housing 11 and the controller radiator 2.

[0055] The temperature detection unit and the drive motor are both communicatively connected to the controller. The temperature detection unit can detect the temperature of the radiator housing 11 and the controller radiator 2. If the temperature reaches a preset temperature, the temperature detection unit transmits a signal to the controller, which in turn transmits the signal to the drive motor. The drive motor then drives the fan 12 to rotate, thereby cooling the radiator housing 11 and the controller radiator 2 and ensuring their normal operation. For example, the temperature detection unit is a temperature sensor.

[0056] like Figure 3 As shown, an embodiment of the present invention provides a vehicle, including a frame 5, a domain controller 3 and the aforementioned integrated domain controller cooling system. The domain controller 3 is mounted on the frame 5, and the controller radiator 2 is connected to the domain controller 3 through a pipeline.

[0057] Optionally, the domain controller 3 can be positioned on the front longitudinal beam of the frame 5 to ensure the shortest possible wiring harness, thereby improving the overall integrity and aesthetics of the vehicle and reducing costs.

[0058] Furthermore, the vehicle also includes an electric water pump 6, which is mounted on the frame 5 and is used to drive the coolant to circulate within the integrated domain controller cooling system.

[0059] Alternatively, the electric water pump 6 can be positioned at the junction of the integrated domain controller cooling system and the wiring harness to ensure the shortest possible wiring harness, thereby improving the vehicle's overall integrity and aesthetics and reducing costs.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
