Description

Technical Field

[0001] This utility model relates to an embedded circulating heat dissipation device for electric vehicles, belonging to the field of automotive parts technology. Background Technology

[0002] With the rapid development of electric vehicle technology, the performance and driving range of electric vehicles are constantly improving, but this also places higher demands on the vehicle's heat dissipation performance. The front compartment of an electric vehicle integrates a large number of electronic components, such as controllers and CDUs (charging distribution units), which generate a lot of heat during prolonged operation. If the heat cannot be dissipated in time, the component temperature will become too high, affecting its performance, reliability, and lifespan, and may even cause safety hazards.

[0003] In current technologies, electric vehicles primarily rely on traditional radiators or fans for heat dissipation. However, these methods have several limitations. For instance, radiators are bulky and take up considerable space, hindering lightweight vehicle design; while fans can provide forced cooling, they consume a lot of energy and are prone to noise and vibration during prolonged operation. Furthermore, traditional cooling methods often struggle to achieve precise heat dissipation for components inside the front compartment, resulting in poor overall cooling performance. Utility Model Content

[0004] This invention provides an embedded circulating heat dissipation device for electric vehicles to overcome the shortcomings of the prior art. It provides a device that does not require additional energy consumption or complex heat dissipation devices, and achieves precise and efficient heat dissipation for the components inside the front compartment.

[0005] This utility model provides an embedded circulating heat dissipation device for electric vehicles, which includes a bumper assembly. The bumper assembly is provided with a heat dissipation part, which includes a heat dissipation panel and an air duct. The air duct is located on the heat dissipation panel and includes a small diameter part and a large diameter part. The small diameter part and the large diameter part are connected by a transition part, and the two ends of the transition part are designed with variable diameters.

[0006] Preferably, the heat dissipation panel is connected to the bumper assembly via a snap-fit ​​mechanism.

[0007] There are multiple air ducts, which are linearly distributed on the heat dissipation panel.

[0008] The transition section has a continuous curvature transition between its two ends and the small-diameter and large-diameter sections.

[0009] The small-diameter section is located inside the heat dissipation panel, and the large-diameter section is located outside the heat dissipation panel.

[0010] The air duct is equipped with an insect-proof component, which includes a fixing cover and an insect-proof net. The fixing cover is connected to the air duct, and the insect-proof net is located at the end of the fixing cover away from the air duct.

[0011] The fixed cover is connected to the large-diameter part by threads.

[0012] The fixed cover is provided with a limiting component corresponding to the insect-proof net. The limiting component includes a limiting frame and a limiting spring. The limiting spring is located on the limiting frame. The insect-proof net is provided with a limiting protrusion that is fixedly connected. The end of the limiting protrusion away from the insect-proof net is connected to the limiting spring.

[0013] The fixed cover is provided with a cleaning plate corresponding to the insect-proof net, and the cleaning plate is provided with cleaning protrusions corresponding to the insect-proof net.

[0014] There are multiple limiting components, which are arranged in a circle on the inner wall of the fixed cover, and the insect net is slidably connected to the limiting components.

[0015] The beneficial effects of this utility model are:

[0016] This invention provides an embedded circulating cooling device for electric vehicles. Utilizing Bernoulli's principle through ductwork, the airflow speed increases and temperature decreases as it passes through the duct, effectively cooling the interior of the electric vehicle's front compartment. Without additional energy consumption, it leverages pure aerodynamics to achieve precise and efficient heat dissipation for components inside the front compartment, thereby reducing energy consumption, improving the vehicle's range, and extending the lifespan of related components. The ductwork is completely embedded within the bumper assembly without adding any protruding structures, maintaining the vehicle's streamlined design and optimizing the drag coefficient, thus indirectly improving the driving range. Insect-proof components effectively prevent flying insects, dust, and other debris from entering the front compartment, avoiding blockage of cooling channels or adhesion to components that could affect heat dissipation efficiency. Simultaneously, the insect-proof net is connected to the large-diameter section of the ductwork via a fixed cover and threaded connection, ensuring the stability of the interception structure and preventing the net from falling off due to high-speed airflow or vibration. Limiting components and a cleaning plate facilitate convenient cleaning of the insect-proof net. When dust and debris accumulate on the insect screen, simply press the screen inwards to clean it using the cleaning protrusions on the cleaning board. This eliminates the need to remove the fixing cover, greatly improving cleaning efficiency. Attached Figure Description

[0027] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1: This utility model provides an embedded circulating heat dissipation device for electric vehicles, which includes a bumper assembly 1. The bumper assembly 1 is provided with a heat dissipation part 2. The heat dissipation part 2 includes a heat dissipation panel 21 and air ducts 22. The heat dissipation panel 21 is located on the bumper assembly 1. The heat dissipation panel 21 is provided with multiple air ducts 22, which are linearly distributed on the heat dissipation panel 21. The air ducts 22 include a small diameter part 221 and a large diameter part 222. The small diameter part 221 and the large diameter part 222 are connected by a transition part 223. The two ends of the transition part 223 are continuously curved with the small diameter part 221 and the large diameter part 222. The two ends of the transition part 223 are designed with a variable diameter. The large diameter part 222 is located on the outside of the heat dissipation panel 21, and the small diameter part 221 is located on the inside of the heat dissipation panel 21. The heat dissipation panel 21 is connected to the bumper assembly 1 by a buckle.

[0029] During use, the heat dissipation panel 21 is fixed to the bumper assembly 1 by clips. Multiple air ducts 22 are fixedly installed on the heat dissipation panel 21. When the vehicle is in motion, outside air enters the front compartment of the electric vehicle through the air ducts 22. The outer side of the air duct 22 has a large diameter, and the end near the front compartment of the electric vehicle has a small diameter. According to Bernoulli's principle, when outside air enters through the large diameter part 222 and flows out through the small diameter part 221, the air is compressed, which increases the airflow speed and decreases the temperature, thereby cooling the interior of the front compartment of the electric vehicle. This reduces the temperature of components such as the controller and CDU inside the front compartment of the electric vehicle, reduces energy consumption, and extends service life.

[0030] Compared to existing designs, the large-diameter section 222 and the small-diameter section 221 in the duct 22, along with the smoothly transitioned section 223, utilize Bernoulli's principle to increase the airflow speed. Simultaneously, gas expansion leads to a temperature drop, resulting in superior heat dissipation with zero additional energy consumption and pure aerodynamic utilization. The accelerated, low-temperature airflow precisely covers high-heat components such as the controller and CDU in the electric vehicle's front compartment, preventing performance degradation caused by localized high temperatures. This effectively cools the interior of the electric vehicle's front compartment, reducing the operating temperature of components like the controller and CDU. This lower operating temperature reduces energy consumption and contributes to improved performance of the electric vehicle. The improved range and lower operating temperature extend the lifespan of related components. The transition section 223 of the air duct 22 features a continuous curvature transition, effectively reducing airflow separation and turbulence, ensuring stable airflow into the front compartment. Compared to traditional right-angle air ducts, the uniformity of heat dissipation is significantly improved. Multiple air ducts 22 are linearly arranged along the heat dissipation panel 21, forming a uniform air intake surface and avoiding heat dissipation dead zones. Simultaneously, they conform to the curved shape of the bumper assembly 1, reducing the negative impact on the vehicle's aerodynamics. The air ducts 22 are completely embedded inside the bumper assembly 1 without adding any extra protruding structures, maintaining the streamlined design of the vehicle body and optimizing the drag coefficient, indirectly increasing the driving range. Furthermore, the heat dissipation panel 21 is fixed to the bumper assembly 1 with clips, without occupying additional space.

[0031] Example 2: In the above example, the air duct 22 is an open design, which makes it easy for flying insects, dust, leaves and other debris to be sucked in during vehicle operation. After these debris enter the front compartment, they may block the heat dissipation channel or adhere to precision components such as controllers and CDUs, affecting heat dissipation efficiency or even causing damage to the components. Therefore, this application example optimizes the air duct 22 based on the above example.

[0032] In this embodiment, the duct 22 is provided with an insect-proof component 3. The outer wall of the large-diameter part 222 is provided with a thread corresponding to the insect-proof component 3. The insect-proof component 3 includes a fixing cover 31 and an insect-proof net 32. The inner wall of the fixing cover 31 is connected to the large-diameter part 222 by a thread. The fixing cover 31 is smoothly connected to the outer wall of the duct 22. The insect-proof net 32 ​​is located at the end of the fixing cover 31 away from the duct 22.

[0033] During use, the insect-proof component 3 is fixed to the air duct 22 by the threaded connection between the fixed cover 31 and the large diameter part 222. During the process of cooling the interior of the electric vehicle's front compartment while the vehicle is in motion, the insect-proof net 32 ​​in the insect-proof component 3 intercepts flying insects and small particles in the air.

[0034] Compared with existing technologies, the insect net 32, located at the end of the fixed cover 31 away from the air duct 22, can intercept flying insects and particulate matter while avoiding excessive wind resistance. The insect net 32 ​​is threadedly connected to the large-diameter section 222 of the air duct 22 through the fixed cover 31, ensuring a stable interception structure and preventing the insect net from falling off due to high-speed airflow or vibration. The shape of the fixed cover 31 is smoothly connected to the outer wall of the large-diameter section 222, avoiding airflow separation and turbulence, and ensuring stable heat dissipation efficiency.

[0035] Example 3: In the above embodiments, the insect net 32 ​​is prone to accumulating dust and debris, which affects the ventilation effect and is difficult to clean. Therefore, this application embodiment optimizes the air duct 22 based on the above embodiments.

[0036] In this embodiment, the inner wall of the fixed cover 31 is provided with a limiting component 33 corresponding to the insect net 32. The limiting component 33 consists of multiple components fixedly arranged on the inner wall of the fixed cover 31. The limiting component 33 includes a limiting frame 331 and a limiting spring 332. The limiting frame 331 has a cavity inside, and the limiting spring 332 is located inside the cavity. The limiting frame 331 is fixedly connected to the inner wall of the fixed cover 31. The outer side of the insect net 32 ​​is provided with multiple circumferentially distributed limiting protrusions 321. The limiting protrusions 321 are fixedly connected to the insect net 32. The limiting frame 331 has a notch corresponding to the limiting protrusion 321. The notch is connected to the cavity. The limiting protrusion 321 extends through the notch into the cavity and is connected to the top of the limiting spring 332. The limiting protrusion 321 is slidably connected to the cavity.

[0037] The fixed cover 31 is provided with a cleaning plate 34 corresponding to the insect net 32. The cleaning plate 34 is located at the end of the insect net 32 ​​near the air duct 22 and is fixedly connected to the inner wall of the fixed cover 31. The cleaning plate 34 is provided with a cleaning protrusion 341 corresponding to the insect net 32 ​​on the side near the insect net 32.

[0038] When the insect net 32 ​​accumulates too much dust and debris, affecting the ventilation effect, pressing the insect net 32 ​​inward will move it towards the cleaning plate 34. The cleaning protrusions 341 on the cleaning plate 34 will clean the dust and debris in the insect net 32, ensuring the normal ventilation effect of the insect net 32. During the movement of the insect net 32 ​​towards the cleaning plate 34, the limiting spring 332 will start to be stressed. When the force applied to the insect net 32 ​​is no longer applied, the limiting spring 332 will reset the insect net 32.

[0039] Compared with existing technologies, by pressing the insect net 32 ​​inward, the limiting protrusion 321 compresses the limiting spring 332, causing the insect net 32 ​​to move towards the cleaning plate 34. The cleaning protrusion 341 automatically scrapes the dust off the surface of the insect net without disassembling the fixing cover 31. The scraping path covers the entire surface of the insect net 32, and the actual cleaning efficiency reaches over 90%. The airflow rate is restored to 98% of the initial state. After releasing the insect net 32, the limiting spring 332 pushes the limiting protrusion 321 to reset, and the insect net 32 ​​returns to its original position, avoiding manual adjustment of the position.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
