[0034] With the rapid development of the automotive industry, engine power is constantly increasing, and the amount of heat generated is also increasing. To ensure that the engine operates within a safe and reliable temperature range, the importance of the vehicle cooling system is becoming increasingly prominent. The vehicle cooling system is a key system for maintaining the normal operating temperature of the engine; it absorbs and dissipates the heat generated by the engine through circulating coolant, preventing overheating.

[0035] The main components of a vehicle's cooling system include a water pump, radiator, thermostat, fan, and coolant. The water pump pumps coolant from the radiator to the engine, carrying away engine heat. The radiator, also known as the water tank, dissipates coolant heat through airflow. The thermostat controls the coolant circulation path and adjusts the airflow into the radiator based on engine temperature. The fan activates when the engine temperature is too high, increasing airflow and improving cooling efficiency. Coolant is the liquid used to absorb and dissipate engine heat; it is typically water, antifreeze, or other mixtures.

[0036] Vehicle cooling systems rely on coolant circulation for heat dissipation. The coolant circulates under the action of the engine and water pump, absorbing the heat generated by the engine. The coolant flows through the radiator, dissipating the heat into the air; the thermostat adjusts the airflow into the radiator based on the engine temperature, maintaining the engine temperature within a suitable range.

[0037] The vehicle's cooling system is a crucial component, and its working principle and design factors affect heat dissipation efficiency, which in turn affects the engine's normal operating temperature. Regular maintenance and upkeep ensure the proper functioning of the cooling system and extend engine life.

[0038] In traditional technology, vehicle cooling systems mainly consist of components such as water pumps, radiators, thermostats, and fans. As the core component of the cooling system, the radiator is responsible for dissipating the heat absorbed by the coolant into the air, preventing the engine from overheating.

[0039] The working principle of a vehicle's cooling system is as follows:

[0040] Coolant circulation: The coolant flows under the action of the engine and water pump, absorbing the heat generated by the engine.

[0041] Heat transfer: The coolant flows through the heat pipes, transferring heat to the heat sinks outside the heat pipes.

[0042] Heat exchange: The heat sink exchanges heat with the air, dissipating the heat from the coolant into the air.

[0043] Temperature control: The thermostat adjusts the coolant circulation route according to the engine temperature and controls the air intake of the cooling system to keep the engine temperature within a suitable range.

[0044] However, traditional vehicle cooling systems have some problems, such as:

[0045] Low fin thermal radiation efficiency: Existing heat dissipation devices use traditional fin structures, which have low thermal radiation efficiency, resulting in poor heat dissipation.

[0046] Large core size: In order to improve heat dissipation efficiency, existing heat dissipation devices usually use a large core size, which increases the weight of the vehicle and the space occupied.

[0047] High fan power consumption: Existing heat dissipation devices use fans to accelerate the heat radiation of the fins, resulting in high fan power consumption, which is not conducive to energy conservation and environmental protection.

[0048] Therefore, it is necessary to provide a new type of vehicle cooling device to improve heat dissipation efficiency, reduce core size, and reduce fan power consumption, thereby improving the performance and reliability of the vehicle cooling system.

[0049] In one exemplary embodiment, please refer to Figure 1 and Figure 2 A vehicle cooling device is provided, which includes a housing, a core 20, and a battery module.

[0050] The housing has at least one fan 110, which is used for heat dissipation of the vehicle cooling system.

[0051] Optionally, the main body of the vehicle cooling device is a housing, on which a fan 110 is mounted. For example, there are two fans. The fan 110, as an important heat dissipation component of the vehicle cooling device, is used to dissipate heat from the vehicle cooling system and control the vehicle engine temperature.

[0052] The core 20 is connected to the shell. The core 20 includes fins 210, cooling plates 220 and flat tubes 230. The fins 210 are disposed at the hot end of the cooling plates 220 and the cooling plates 220 are disposed on the flat tubes 230. The fins 210 are used to dissipate heat from the hot end of the cooling plates and the cooling plates 220 are used to cool the coolant inside the flat tubes 230.

[0053] Optionally, the core 20 is a crucial component for the vehicle's cooling system to achieve its heat dissipation function. It is connected to the main housing of the vehicle's cooling system. The core 20 specifically includes fins 210, cooling plates 220, and a flat tube 230. The fins 210 are located at the hot end of the cooling plate 220, increasing its heat dissipation efficiency. The cooling plates 220 are mounted on the flat tube 230, which has ample installation space, allowing for the installation of multiple cooling plates 220 to further improve heat dissipation efficiency.

[0054] The battery module is connected to the fan 110 and the cooling chip 220 respectively, and is used to power the fan 110 and / or the cooling chip 220.

[0055] Optionally, the battery module is connected to both the fan 110 and the cooling chip 220, converting the battery current into a current suitable for the vehicle's cooling system. The battery module can supply power to either the fan 110 or the cooling chip 220 individually, or simultaneously, depending on the cooling requirements of the vehicle's cooling system.

[0056] The aforementioned vehicle cooling device increases the heat dissipation efficiency of the hot end of the cooling chip 220 by installing fins 210 on the hot end of the cooling chip 220; by installing the cold end of the cooling chip 220 on the flat tube 230 of the cooling device, more cooling chips 220 can be installed, resulting in higher heat dissipation efficiency; by powering the fan 110 and / or the cooling chip 220 through the battery module, different heat dissipation needs can be met, saving vehicle energy. At the same time, the battery module increases the thermal radiation efficiency of the fins 210 of the cooling device, reduces the core size, and optimizes the overall vehicle space layout.

[0057] In one exemplary embodiment, please refer to Figure 1 and Figure 2 The shell includes a left water chamber 120, a right water chamber 130, an inlet 140, and an outlet 150.

[0058] The left water chamber 120 is connected to the inlet 140 so that coolant enters the left water chamber 120 through the inlet 150.

[0059] The right water chamber 130 is connected to the outlet 150 so that the coolant enters the right water chamber 130 through the flat tube 230 and flows out of the right water chamber 130 through the outlet 150.

[0060] For example, the left water chamber 120 is located on the left side of the housing, and its internal space is used to contain coolant. The left water chamber 120 is made of a high-strength, corrosion-resistant material to ensure that it is not easily damaged during long-term use.

[0061] The right water chamber 130 is located on the right side of the casing, opposite the left water chamber 120. It is also made of high-strength, corrosion-resistant material and is used to temporarily store coolant. The inlet 140 is located at an appropriate position on the casing (e.g., slightly below the left water chamber 120) and connected to it. The size and shape of the inlet 140 are matched to the coolant piping to ensure smooth coolant flow into the left water chamber 120. The outlet 150 is located on the other side of the casing and connected to the right water chamber 130. The size and shape of the outlet 150 are also optimized to match the coolant piping to ensure smooth coolant flow out of the right water chamber 130.

[0062] For example, coolant enters the left water chamber 120 through inlet 140. During this process, the coolant carries away the heat generated during equipment operation. Subsequently, the coolant flows within the left water chamber 120 and enters the right water chamber 130 through the flat tube 230. The design of the flat tube 230 increases the contact area between the coolant and the inner wall of the housing, improving the cooling effect. After a brief stay in the right water chamber 130, the coolant flows out of the housing through outlet 150. The coolant flowing out of the housing carries away heat, thus cooling the equipment.

[0063] In the above embodiment, when the vehicle cooling system is working, the coolant enters the left water chamber 120 through the inlet 140, enters the right water chamber 130 through the flat tube 230, and flows out of the right water chamber 130 through the outlet 150, so as to realize the circulation and heat dissipation of the coolant.

[0064] In one exemplary embodiment, please refer to Figure 1 and Figure 2 The housing also includes an upper side plate 160, a lower side plate 170, a left side plate 180, and a right side plate 190.

[0065] The core 20 has an upper side plate 160 above it and a lower side plate 170 below it.

[0066] The left water chamber 120 has a left side plate 180 on the left side, and the right water chamber 130 has a right side plate 190 on the right side.

[0067] For example, the housing includes an upper side plate 160, a lower side plate 170, a left side plate 180, and a right side plate 190 for supporting or fixing the components in the core 20 of the vehicle cooling system. The upper side plate 160 is located above the core 20 and is made of a lightweight, corrosion-resistant material to ensure structural stability and durability.

[0068] The lower plate 170 is located below the core 20, corresponding to the upper plate 160, together forming the bottom of a complete cooling system. The lower plate 170 is also made of lightweight, corrosion-resistant material to reduce overall weight and improve corrosion resistance.

[0069] The left side plate 180 is located to the left of the left water chamber 120, providing lateral support for the cooling system. The right side plate 190 is located to the right of the right water chamber 130, corresponding to the left side plate 180, providing support for the cooling system on the other side. The material and structural design of the right side plate 190 ensures the overall strength of the housing.

[0070] In one exemplary embodiment, please refer to Figure 1 and Figure 2 The casing also includes a wind shield 111.

[0071] The wind shield 111 is equipped with a fan 110 and is screwed to the upper side plate 160 and the lower side plate 170.

[0072] For example, the primary function of the fan shield 111 is to protect the fan 110 and guide the airflow direction. The fan shield 111 is made of high-strength, corrosion-resistant material to ensure long-term stable operation. Multiple fans 110 are symmetrically arranged on the fan shield 111, enabling them to assist in coolant heat exchange during operation and achieve optimal heat dissipation. To improve installation stability, the fan shield 111 is connected to the upper plate 160 and the lower plate 170 by bolts. Screw holes are provided on both sides of the fan shield 111, and corresponding screw holes are also provided on the upper plate 160 and the lower plate 170. The fan shield 111, the upper plate 160, and the lower plate 170 are tightly connected together by bolts, thereby ensuring the stability of the fan 110 during operation.

[0073] In the above embodiments, the wind shield 111 and its screw connection structure with the upper side plate 160 and the lower side plate 170 have the advantages of easy installation, compact structure, easy maintenance and strong expandability, and are suitable for various vehicle heat dissipation scenarios.

[0074] In one exemplary embodiment, please refer to Figure 2 The battery module includes a high-voltage battery 310, a high-voltage wiring harness 320, a DC-DC converter 330, and a low-voltage wiring harness 340.

[0075] The high-voltage battery 310 is connected to the DC-DC converter 330 via the high-voltage wiring harness 320. The DC-DC converter 330 is connected to the fan 110 and the cooling chip 220 via the low-voltage wiring harness 340 to generate a low-voltage DC current to power the fan 110 and / or the cooling chip 220.

[0076] For example, the battery module provides a stable power supply for the entire vehicle's cooling system. The battery module includes components such as a high-voltage battery 310, a high-voltage wiring harness 320, a DC-DC converter 330, and a low-voltage wiring harness 340.

[0077] The high-voltage battery 310, as the core power unit of the battery module, adopts a high energy density and long lifespan design, providing a stable high-voltage output. The high-voltage battery 310 is connected to the DC-DC converter 330 via a dedicated high-voltage wiring harness 320. The high-voltage wiring harness 320 is made of high-voltage resistant and wear-resistant materials, possessing excellent insulation performance and anti-interference capabilities, ensuring the safety and reliability of power transmission.

[0078] The DC-DC converter 330, as an important conversion device in the battery module, mainly functions to convert the high voltage output from the high-voltage battery 310 into a low-voltage DC current. The DC-DC converter 330 features efficient and stable conversion performance, capable of meeting the voltage requirements of the fan 110 and the cooling chip 220 under different operating conditions.

[0079] The DC-DC converter 330 is connected to the fan 110 and the cooling chip 220 via a low-voltage wiring harness 340. The low-voltage wiring harness 340 is made of a flexible, wear-resistant material with good conductivity and tensile strength. The low-voltage wiring harness 340 transmits the converted low-voltage DC current to the fan 110 and / or the cooling chip 220, providing them with a stable power supply.

[0080] In the above embodiments, the design of high-voltage battery 310 and low-voltage wiring harness 340 effectively reduces the risk of system short circuit and electric shock; the output voltage of DC-DC converter 330 can be adjusted according to the actual voltage requirements of fan 110 and cooling chip 220 to meet the usage requirements of different scenarios; the layout of each component of the battery module is clear and easy to maintain.

[0081] In one exemplary embodiment, the battery module is also used to supply power to the fan 110 when the heat dissipation demand of the vehicle cooling system is below a preset threshold.

[0082] For example, when the heat dissipation demand of the vehicle cooling system is low, the DC-DC converter 330 converts the high voltage of the high voltage battery 10 into low voltage to power the fan 110. The fan 110 starts to work, and the coolant in the flat tube 230 radiates heat through the fins 210 below the flat tube 230.

[0083] In one exemplary embodiment, the battery module is also used to supply power to the cooling chip 220 and the fan 110 when the heat dissipation demand of the vehicle cooling system is higher than a preset threshold.

[0084] For example, when the heat dissipation demand of the automotive cooling system is high, the DC-DC converter 330 converts the high-voltage electricity of the high-voltage battery 310 into low-voltage electricity to power the cooling chip 220 and the fan 110. The cold end of the cooling chip 220 starts to cool, and the coolant in the flat tube 230 is radiated with heat through the cooling chip 220 above the flat tube 230 and the fins 210 below the flat tube 230. The hot end of the cooling chip 220 is radiated with heat through the fins 210 below the flat tube 230. The fan 110 is used to improve the heat radiation efficiency of the fins 210.

[0085] In the two embodiments described above, when the vehicle cooling system has a high heat dissipation demand, the fan 110 and the cooling chip 220 work simultaneously; when the vehicle cooling system has a low heat dissipation demand, only the fan 110 works, thus saving vehicle energy.

[0086] In one exemplary embodiment, the refrigeration chip 220 is a semiconductor refrigeration chip, and the cold end of the refrigeration chip 220 is attached above the flat tube 230.

[0087] For example, the thermoelectric cooler 220 utilizes the Peltier effect to transfer heat through the flow of current in the semiconductor material, thereby achieving a cooling effect. The cold end of the cooler 220 is attached above the flat tube 230. This arrangement ensures that during operation, the cold end of the cooler 220 can directly contact the flat tube 230, thereby efficiently absorbing and transferring heat from the flat tube 230, achieving the purpose of reducing the temperature of the flat tube 230 and its surrounding components.

[0088] In one exemplary embodiment, fins 210 are welded below flat tube 230.

[0089] For example, the fins 210 are made of high-quality thermally conductive material, featuring a thin and porous structure that helps increase their contact area with air, thereby improving heat exchange efficiency. The flat tube 230, as the main component of the heat exchanger, carries coolant internally and exchanges heat with the fins 210 externally. The material selection and shape design of the flat tube 230 are based on the principles of efficient heat exchange and structural stability.

[0090] During the welding process, the welding temperature, time, and welding materials are strictly controlled to avoid adverse effects on the material properties of the fins 210 and the flat tube 230. The fins 210 are located below the flat tube 230; this arrangement facilitates airflow, reduces airflow resistance, and improves heat exchange efficiency. Simultaneously, the bottom welding design also helps prevent damage to the fins 210 from external factors such as impact and corrosion.

[0091] Through precision welding, the fins 210 and the flat tube 230 achieve excellent heat conduction and mechanical connection. During heat exchange, heat can be rapidly transferred from the flat tube 230 to the fins 210 and then dissipated into the surrounding air through the fins 210, thereby achieving efficient heat dissipation.

[0092] In one exemplary embodiment, the present invention also provides a vehicle including the vehicle cooling device of any of the above embodiments.

[0093] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0094] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
