Description

Technical Field

[0001] This invention relates to the field of outdoor charging technology, specifically to an outdoor car charging station with a ventilation and heat dissipation structure. Background Technology

[0002] With the popularization of new energy vehicles, the demand for outdoor car charging stations has surged. These stations operate under high loads for extended periods in complex environments such as high temperatures, dust storms, rain, and snow. Internal power modules and control circuits are prone to generating significant heat, and temperature rise directly impacts equipment lifespan and operational safety. Existing technologies often employ air cooling, liquid cooling, or combined cooling solutions. However, liquid cooling or combined cooling requires higher material costs and has a shorter lifespan compared to air cooling. Therefore, air cooling is generally used in outdoor car charging stations. Air cooling typically uses a fan to blow air into the heating modules, carrying away heat from their surfaces. However, existing outdoor car charging stations have complex structures, making it difficult for air to escape. Heat carried away from the heating modules tends to accumulate in heat dissipation dead zones within the charging station, hindering proper heat dissipation. Furthermore, the lack of gaps between adjacent heating modules makes it difficult for heat to dissipate through contact with air. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an outdoor car charging pile with a ventilation and heat dissipation structure to solve the problems of small contact area between the heating module and the flowing air and low heat dissipation efficiency mentioned in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an outdoor car charging pile with a ventilation and heat dissipation structure, including a chassis, wherein the chassis is provided with a plurality of heat dissipation chambers for placing heat-generating modules, an air inlet mechanism and an air outlet mechanism, the air inlet mechanism and the air outlet mechanism are arranged on both sides of the heat dissipation chamber, the heat dissipation chamber is arranged through the air inlet mechanism and the air outlet mechanism, the air inlet mechanism blows air from one side of the heat dissipation chamber to the other side, and there is a gap between the inner wall of the heat dissipation chamber and the heat-generating module for air to pass through.

[0005] As a further improvement of the present invention, a baffle is provided on both sides of the heat dissipation chamber, and the baffles on both sides arrange several heat dissipation chambers in a straight line from top to bottom. The baffles are fixedly connected to the heat dissipation chambers by bolts, and air inlet honeycomb mesh is provided on both sides of each heat dissipation chamber.

[0006] As a further improvement of the present invention, there is a heat insulation gap between two adjacent heat dissipation chambers, and the baffle is provided with a blocking part for preventing air from entering the heat insulation gap at the corresponding position of the heat insulation gap.

[0007] As a further improvement of the present invention, the air outlet mechanism includes a louver and a heat-conducting block disposed between the louver and the heat dissipation chamber. The louver has a plurality of fan blades evenly distributed along its length direction, and an outlet is provided between two adjacent fan blades. The heat-conducting block can absorb air passing through the heat dissipation chamber and discharge it to the outside through the outlet.

[0008] As a further improvement of the present invention, the fan blade includes a first limiting part, a second limiting part, and a guiding part. The first limiting part is used to prevent air from flowing back into the chassis, and the second limiting part is used to restrict the airflow direction so that it can be discharged downward after passing through the output port.

[0009] As a further improvement of the present invention, the first limiting part is L-shaped and has a notch, which can be used to block some dust from entering the chassis.

[0010] As a further improvement of the present invention, the second limiting part is arranged at the same horizontal line as the outer wall of the louver.

Detailed Implementation

[0015] As shown in the figure, an embodiment of the present invention provides an outdoor car charging pile with a ventilation and heat dissipation structure to achieve the above objectives. The pile includes a chassis 1, which contains a plurality of heat dissipation chambers 2 for housing heat-generating modules 3, an air inlet mechanism 4, and an air outlet mechanism 5. The air inlet mechanism 4 and the air outlet mechanism 5 are arranged on both sides of the heat dissipation chambers 2, and the heat dissipation chambers 2 are arranged in a through manner on both sides of the air inlet mechanism 4 and the air outlet mechanism 5. The air inlet mechanism 4 blows air from one side of the heat dissipation chamber 2 to the other side. There is a gap 6 between the inner wall of the heat dissipation chamber 2 and the heat-generating module 3 for air to pass through.

[0016] In this implementation, the chassis 1 is made of cold-rolled steel plate in one piece, possessing excellent outdoor corrosion resistance and pressure resistance. Inside the chassis 1, several heat dissipation chambers 2 are arranged according to the heat-generating modules 3. The number of heat dissipation chambers 2 can be adjusted according to the power of the charging pile; for example, when accommodating 3 heat-generating modules 3, 3 independent heat dissipation chambers 2 are set up. Air intake mechanisms 4 and air exhaust mechanisms 5 are respectively installed on the left and right sides of the heat dissipation chambers 2, forming a symmetrical arrangement. Both sides of the heat dissipation chambers 2 corresponding to the air intake mechanisms 4 and air exhaust mechanisms 5 are made through-hole, removing side wall obstructions to ensure smooth airflow. After the air intake mechanism 4 is activated, the airflow can flow from the direction of the air intake mechanism 4 towards the direction of the air exhaust mechanism 5, forming a directional airflow that continuously blows external air from one side of the heat dissipation chamber 2 to the other side, and finally exhausts it through the air exhaust mechanism 5. A gap 6 is reserved between the inner wall of the heat dissipation chamber 2 and the heating module 3 for air to pass through. The width of the gap 6 can be adapted according to the size of the heating module 3. During assembly, the heating module 3 is fixed in the middle of the heat dissipation chamber 2 by the bracket, so that the gap 6 is evenly distributed around the heating module 3, ensuring that the airflow can fully wrap the surface of the heating module 3, carry away the heat generated during operation, and avoid local heat accumulation.

[0017] As an improved specific implementation, a baffle 7 is provided on both sides of the heat dissipation chamber 2. The baffles 7 arrange several heat dissipation chambers 2 in a straight line from top to bottom. The baffles 7 are fixedly connected to the heat dissipation chambers 2 by bolts 8. An air inlet honeycomb mesh 9 is provided on both sides of each heat dissipation chamber 2.

[0018] In this implementation, a baffle 7 is installed on both the upper and lower sides of the heat dissipation chamber 2. The baffle 7 is made of cold-rolled steel plate with the same material as the chassis 1, and its thickness is adapted to the side wall of the chassis 1 to ensure structural strength. The two baffles 7 are arranged in parallel, arranging several heat dissipation chambers 2 in a straight line from top to bottom. Adjacent heat dissipation chambers 2 are tightly fitted together to ensure space utilization. The baffle 7 is fixed to the heat dissipation chamber 2 with bolts 8. Through holes are opened at corresponding positions on the side wall of the heat dissipation chamber 2, and the inner bolts 8 are fastened through the through holes and threaded holes. An air inlet honeycomb mesh 9 is fixedly installed on both sides of each heat dissipation chamber 2 on the baffle 7. The air inlet honeycomb mesh 9 is made of stainless steel. The aperture of the air inlet honeycomb mesh 9 can be small-diameter to block hair and other debris during air intake, ensuring smooth air intake. The appropriate aperture can be selected according to the outdoor dust concentration scene. The honeycomb mesh can be detachably connected to the baffle 7 with clips for easy regular dust cleaning. In this solution, the honeycomb mesh and the baffle 7 are integrally molded, making manufacturing more convenient and reducing costs.

[0019] As an improved embodiment, a heat insulation gap 10 is provided between two adjacent heat dissipation chambers 2, and a baffle 7 is provided with a blocking part 11 for blocking air from entering the heat insulation gap 10 at the position corresponding to the heat insulation gap 10.

[0020] In this solution, a heat insulation gap 10 is reserved between two adjacent heat dissipation chambers 2. The heat insulation gap 10 can prevent heat transfer between adjacent heat dissipation chambers 2 and prevent heat accumulation that could lead to excessive local temperature rise. The width of the heat insulation gap 10 is reasonably set according to the internal space of the chassis 1. The baffle 7 has an integrally formed blocking part 11 corresponding to the position of the heat insulation gap 10. In this solution, the blocking part 11 and the baffle 7 are integrally stamped, resulting in a stable structure and good sealing performance. In other embodiments, those skilled in the art can also fix the blocking part 11 to the baffle 7 by welding, and seal the weld. Both implementation methods can effectively block airflow from entering the heat insulation gap 10, ensuring that all airflow flows through the ventilation gap 6 in the heat dissipation chamber 2, ensuring heat dissipation efficiency, and preventing dust from accumulating in the heat insulation gap 10.

[0021] As an improved specific implementation, the air outlet mechanism 5 includes a louver 12 and a heat-conducting block 13 disposed between the louver 12 and the heat dissipation chamber 2. The louver 12 has a plurality of fan blades 14 evenly distributed along its length direction, and an outlet 15 is provided between two adjacent fan blades 14. The heat-conducting block 13 can absorb the air passing through the heat dissipation chamber 2 and discharge it to the outside through the outlet 15.

[0022] In this solution, the louver 12 is fixedly mounted on the outer wall of the corresponding heat dissipation chamber 2 on the other side of the chassis 1 and is fastened to the chassis 1 by bolts 8. The heat conduction block 13 is installed between the louver 12 and the heat dissipation chamber 2, fitting against the through end face of the heat dissipation chamber 2. The heat conduction block 13 can be made of aluminum alloy, which is cheaper. Several fan blades 14 are evenly arranged along the length of the louver 12. In this solution, in order to ensure the stability and strength of the fan blades 14 when operating outdoors, the fan blades 14 are fixedly connected to the frame of the louver 12. In other solutions, the fan blades 14 can be rotatably connected to the frame of the louver 12, and the angle can be finely adjusted according to the airflow direction. An outlet 15 for the exhaust of heated air is formed between two adjacent fan blades 14. During operation, the hot air after heat exchange in the heat dissipation chamber 2 flows through the heat conduction block 13, which further absorbs the residual heat in the air. Then, the hot air is discharged to the outside of the chassis 1 through the output port 15. At the same time, the heat conduction block 13 can dissipate the heat it absorbs to the external environment, thereby improving the overall heat dissipation effect.

[0023] As an improved specific embodiment, the fan blade 14 includes a first limiting part 16, a second limiting part 17 and a guiding part 18. The first limiting part 16 is used to prevent air from flowing back into the chassis 1, and the second limiting part 17 is used to restrict the airflow direction so that it can be discharged downward after passing through the output port 15.

[0024] In this design, the central fan blade 14 is integrally formed with a first limiting part 16, a second limiting part 17, and a guide part 18. These three parts work together to guide airflow and prevent backflow. The guide part 18 is located in the middle of the fan blade 14 and is used to guide hot air towards the outlet 15. The first limiting part 16 is located at the end of the fan blade 14 near the inside of the chassis 1. Its structural design can prevent external air from flowing back into the chassis 1, avoiding the mixing of hot and cold air and affecting heat dissipation. The second limiting part 17 is located at the end of the fan blade 14 near the outlet 15. Through structural limitation, it ensures that air is discharged downwards after passing through the outlet 15, preventing rainwater from flowing back into the chassis 1 with the airflow. The positional relationship between the first limiting part 16, the second limiting part 17, and the guide part 18 is adapted to the airflow direction, ensuring that the first limiting part 16 can effectively block backflow airflow, the second limiting part 17 accurately limits the airflow discharge direction, and the guide part 18 assists in the smooth passage of airflow.

[0025] As an improved embodiment, the first limiting part 16 is L-shaped and has a notch 19, which can be used to block part of the dust from entering the housing 1.

[0026] In this design, the first limiting part 16 adopts an L-shaped structure. The bending direction of the L-shaped first limiting part 16 faces the outside of the chassis 1, forming a recess 19 facing the airflow direction. Its depth is reasonably set according to dust prevention requirements, which can both block some dust from entering the chassis 1 and not affect the normal airflow. When external air flows through the louvers 12 with dust, the dust particles are easily impacted by inertia and hit the inner wall of the recess 19 of the L-shaped first limiting part 16. Some dust will adhere to the recess 19 and cannot enter the chassis 1 with the airflow, thereby reducing the accumulation of dust on the surface of the heat dissipation chamber 2 and the heat generation module 3. The L-shaped first limiting part 16 and the fan blade 14 are integrally injection molded, which is suitable for complex outdoor environments. The inner wall of the recess 19 can be smoothed to facilitate the later cleaning of the attached dust. This design adopts an L-shaped structure at both the air inlet and outlet positions.

[0027] As an improved embodiment, the second limiting part 17 is arranged at the same horizontal line as the outer side wall of the louver 12.

[0028] In this solution, the second limiting part 17 is set at the same horizontal line as the outer wall of the louver 12. This setting allows the second limiting part 17 to guide the airflow more accurately, avoids the airflow discharge direction deviation caused by height deviation, and ensures that the hot air can be stably discharged in the horizontal downward direction after passing through the outlet 15, further improving the rainproof effect. In addition, the second limiting part 17 set in this way will not protrude beyond the outer periphery of the chassis 1, making the chassis 1 more beautiful and neat overall.

[0029] As an improved specific implementation, the air intake mechanism 4 consists of several fans 20 arranged in a straight line from top to bottom, with at least one fan 20 corresponding to one side of each heat dissipation chamber 2.

[0030] In implementation, the air intake mechanism 4 employs several fans 20, arranged in a straight line from top to bottom on the inner wall of the casing 1 corresponding to the heat dissipation chamber 2. The fans 20 are fixed to the casing 1 via brackets, which are rust-proofed for outdoor environments. At least one fan 20 is installed on one side of each heat dissipation chamber 2 to ensure sufficient airflow. If the heat dissipation chamber 2 has a high power output, two fans 20 can be installed on one side of a single heat dissipation chamber 2 to increase airflow intensity. Two types of fans 20 are used: axial fans 20, characterized by large air volume and low noise, suitable for conventional heat dissipation needs; and centrifugal fans 20, with higher air pressure, suitable for outdoor scenarios with high dust levels, preventing dust blockage from affecting airflow. The control terminals of the fans 20 are connected to the charging pile control system and start synchronously with the operation of the heating module 3 to achieve on-demand heat dissipation. The fans 20 are aligned with the through-holes of the heat dissipation chamber 2 to ensure that all airflow enters the heat dissipation chamber 2 without leakage or loss.

[0031] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
