[0033] In the vehicle thermal management system, new energy vehicles have added battery circuits and motor circuits compared to traditional power. In order to ensure that the battery, air-conditioning system, and electrical system work efficiently in high and low temperature environments, multiple overflow tanks 11, water pumps, multi-way water valves, heat exchangers, etc. need to be arranged in the thermal management architecture. They are scattered throughout the vehicle, and the low integration results in heavy weight and high cost, and a large amount of cabin space is occupied, which seriously affects the vehicle's cruising range and cabin space utilization.
[0034] In the utility model, a plurality of electrical components 12 are integrated on the overflow tank 11, so as to improve the integration of the thermal management system, reduce the cost and quality, and improve the space utilization of the cabin.
[0035] The electrical device 12 is one or more of an electronic water pump, a multi-way valve, and a heat exchanger. That is, the electrical device 12 can be an electronic water pump, and multiple electronic water pumps are arranged on multiple mounting parts, so that multiple electronic water pumps are installed on the overflow tank 11, and the overflow tank 11 provides mounting points for multiple electronic water pumps. Multiple electronic water pumps are integrated on the overflow tank 11, so as to improve the integration of the thermal management system, reduce costs and quality, and improve the space utilization rate of the cabin.
[0036] The electrical device 12 can be a multi-way valve, and multiple multi-way valves are arranged on multiple mounting parts, so that the multiple multi-way valves can be installed on the overflow tank 11. The overflow tank 11 provides mounting points for the multiple multi-way valves. The multiple multi-way valves are integrated on the overflow tank 11, which improves the integration of the thermal management system, reduces costs and quality, and improves the utilization rate of the cabin space.
[0037] The electrical device 12 can be a heat exchanger, and multiple heat exchangers are arranged on multiple mounting parts, so that multiple heat exchangers can be installed on the overflow tank 11. The overflow tank 11 provides mounting points for multiple heat exchangers. Multiple heat exchangers are integrated on the overflow tank 11 to improve the integration of the thermal management system, reduce costs and quality, and improve cabin space utilization.
[0038] The electrical device 12 may be a combination of an electronic water pump, a multi-way valve and a heat exchanger. The number of the three electrical devices 12, the electronic water pump, the multi-way valve and the heat exchanger, is not limited and is selected according to actual application.
[0039] Furthermore, a plurality of flow channels may be provided inside the overflow tank 11, and the plurality of flow channels may be used to connect the electronic water pump, the multi-way valve and the heat exchanger.
[0040] like Figure 1-Figure 5 As shown, the thermal management integrated architecture 100 also includes: a radiator 21 component, the radiator 21 component includes: a radiator 21 and a cooling fan, the cooling fan is connected to the overflow tank 11, and the radiator 21 is arranged relative to the overflow tank 11 and the cooling fan. Specifically, when the motor, battery, etc. of the thermal management system need to dissipate heat, the radiator 21 and the cooling fan are enabled to dissipate heat for the motor or battery, the radiator 21 and the cooling fan are arranged relative to each other, and the cooling fan drives the airflow through the radiator 21 to take away the heat to achieve the heat dissipation effect. The overflow tank 11 is arranged on the cooling fan, and the cooling fan provides an installation point for the overflow tank 11. The radiator 21 includes: cooling fins 211, the cooling fins 211 are arranged relative to the overflow tank 11 and the cooling fan, so that the airflow passes through the cooling fins 211 to dissipate heat for the overflow tank 11.
[0041] like Figure 1 and Figure 2 As shown, the overflow tank 11 is also provided with an air guide port, which penetrates the overflow tank 11 in a direction away from the radiator 21. Specifically, the air guide port is not connected to the inside of the overflow tank 11, and the air guide port penetrates the overflow tank 11 in a direction away from the radiator 21. Then, the fan drives the airflow to flow through the heat dissipation fins 211 and then flows through the air guide port. The airflow through the air guide port takes away the heat of the overflow tank 11, which plays a role in dissipating the heat of the overflow tank 11; and the air guide port quickly guides the airflow from the heat dissipation fins 211 to the side of the overflow tank 11 away from the radiator 21 to avoid blocking the airflow. The air guide port can quickly cool the coolant in the overflow tank 11, thereby improving the overall cooling performance of the thermal management system.
[0042] Further, the air guide port includes: a plurality of first air guide ports 111, the plurality of first air guide ports 111 are arranged at intervals, and the first air guide ports 111 are irregularly shaped. Specifically, the cross section of the first air guide port 111 may be irregularly shaped, there may be a plurality of first air guide ports 111, the plurality of first air guide ports 111 are arranged at intervals, the shapes of the plurality of first air guide ports 111 may be consistent, or the shapes of the plurality of first air guide ports 111 may be inconsistent. The irregularly shaped air guide port may switch the airflow passing through the heat dissipating fins 211 from a horizontal flow state to a turbulent flow state, thereby improving the cooling capacity of the airflow on the overflow tank 11.
[0043] And, the air guide port also includes: a plurality of second air guide ports 112, the second air guide ports 112 are spaced apart from the first air guide ports 111, and the second air guide ports 112 are one or more of rectangular and polygonal. Specifically, there can be a plurality of second air guide ports 112, the second air guide ports 112 can be rectangular, the second air guide ports 112 can also be polygonal, and among the plurality of second air guide ports 112, a portion can be rectangular second air guide ports 112, and another portion can be polygonal second air guide ports 112. The second air guide ports 112 further increase the contact area between the airflow flowing from the radiator 21 to the overflow tank 11 and the overflow tank 11, thereby improving the heat dissipation capacity of the airflow to the overflow tank 11.
[0044] Combination Figure 1-Figure 5 As shown, the cooling fan includes: a mounting shell 22, a motor and a fan blade 23. The motor is mounted in the mounting shell 22, the motor is connected to the fan blade 23 through a rotating shaft, the mounting shell 22 is fixedly connected to the radiator 21, and the overflow tank 11 is fixedly connected to the mounting shell 22. Specifically, the mounting shell 22 is connected to the radiator 21, the mounting shell 22 is arranged opposite to the heat dissipation fin 211, a circular through hole is provided on the mounting shell 22, the fan blade 23 is arranged in the circular through hole, and the motor is connected to the mounting shell 22. The overflow tank 11 is fixedly connected to the side of the mounting shell 22 away from the radiator 21, and the mounting shell 22 provides a mounting point for the overflow tank 11, thereby improving the utilization rate of the cabin.
[0045] In some embodiments, the mounting housing 22 and the overflow tank 11 are integrally formed. Specifically, the mounting housing 22 and the overflow tank 11 are integrally formed to improve the integration of the thermal management integrated architecture 100 and enhance the space utilization of the cabin.
[0046] like Figure 1 and Figure 5 As shown, a filling port 113 is provided at the top of the overflow tank 11, and the filling port 113 is communicated with the accommodating chamber 114. An exhaust passage is provided in the overflow tank 11, and the exhaust passage is communicated with the accommodating chamber 114. Specifically, when the coolant in the overflow tank 11 is insufficient, the coolant can be added through the filling port 113 to ensure the normal operation of the thermal management system.
[0047] During the process of adding coolant, the gas inside the overflow tank 11 cannot be fully discharged, so that the coolant cannot fill the overflow tank 11. The gas inside the overflow tank 11 needs to be discharged and the coolant needs to be refilled. This operation must be repeated to fill the coolant. During the operation of the vehicle, bubbles will be generated during the circulation of the coolant. The bubbles can be discharged from the exhaust channel to the outside of the overflow tank 11, so as to avoid the bubbles inside the overflow tank 11, which will cause cavitation on the inner wall of the overflow tank 11 and affect the service life of the overflow tank 11.
[0048] In some embodiments, the thermal management integrated architecture 100 is tilted toward the side away from the front bumper, and a front storage box is arranged between the thermal management integrated architecture 100 and the front bumper. Specifically, in the front-to-back direction, the thermal management of the thermal management integrated architecture 100 is tilted upward from front to back, and the side of the radiator 21 in the thermal management integrated architecture 100 away from the overflow tank assembly 10 is arranged opposite to the front storage box, which saves the cabin layout space, can realize a larger space design for the front luggage compartment, and increase the user's storage space.
[0049] The thermal management system according to the second embodiment of the utility model includes: a thermal management integrated architecture 100. The main electrical components 12 of the thermal management system (such as an electronic water pump, a multi-way valve and a heat exchanger) are integrated with the overflow tank 11, and the various parts of the thermal management system are highly integrated to reduce quality and cost. The overflow tank 11 is provided with an air guide port, so that the overflow tank 11 increases the heat dissipation function and improves the overall heat dissipation performance; the overflow tank assembly 10 and the mounting shell 22 can be fixedly connected, that is, the overflow tank assembly 10 is integrated with the cooling fan, which reduces the space requirements of the cabin for the individual arrangement of each part, so that the idle space of the cabin is increased, and the thermal management integrated architecture 100 is arranged at an angle, which can realize a larger front luggage compartment and improve product competitiveness.
