Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a new energy charging pile with heat dissipation function. Background Technology

[0002] New energy charging piles are specialized devices that provide power replenishment for new energy vehicles (mainly electric vehicles). They connect to the vehicle's battery through a specific power interface, converting grid power into DC or AC power that can be stored in the vehicle's battery, thus replenishing the vehicle's energy. They are a core infrastructure of the new energy vehicle industry chain, equivalent to a "gas station" for traditional gasoline vehicles, directly impacting the ease of use and market penetration speed of new energy vehicles.

[0003] A search revealed that patent document CN222473944U discloses a new energy charging pile with heat dissipation function, including a charging pile shell, a water storage mechanism installed at the lower left side of the charging pile shell, a heat dissipation shell fixedly connected to the upper left side of the charging pile shell, and a heat dissipation mechanism installed on the side of the water storage mechanism away from the charging pile shell; the above-mentioned charging pile can effectively improve the heat dissipation effect inside the charging pile shell.

[0004] However, the aforementioned new energy charging piles still have the following technical problems during use:

[0005] 1. During use, the heat exchange efficiency between the cooling water and the high-temperature air inside the heat dissipation shell is low, resulting in poor heat dissipation effect inside the charging pile shell, which cannot meet the cooling requirements of the high-temperature charging mechanism during charging.

[0006] 2. During use, outside air needs to be introduced into the heat dissipation shell to improve the airflow around the charging mechanism. In this process, dust mixed in with outside air will inevitably adhere to the charging mechanism body, which will reduce the heat dissipation effect of the charging mechanism body. In severe cases, dust may even enter the charging mechanism from the gaps, resulting in a decrease in charging efficiency. Utility Model Content

[0007] The purpose of this invention is to solve the problem that the heat dissipation effect inside the casing of the existing charging pile is still poor. It proposes a new energy charging pile with heat dissipation function, which increases the contact area between cooling water and airflow by a serpentine coil and forms a directional circulation of cooling water by a reciprocating screw driving a piston plate, thereby greatly improving the heat exchange efficiency between cooling water and air.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A new energy charging pile with heat dissipation function includes:

[0010] The charging pile housing has a partition fixedly connected inside, which divides the interior of the charging pile housing into a cooling chamber and a placement chamber. The partition has a ventilation channel connecting the cooling chamber and the placement chamber. A charging mechanism is fixedly connected in the placement chamber.

[0011] A ventilation mechanism, located in the cooling chamber, is used to blow outside air into the placement chamber to accelerate air circulation around the charging mechanism. The ventilation mechanism includes an air inlet channel and an air outlet channel fixedly connected to the outer walls of both sides of the charging pile housing. The air inlet channel and the air outlet channel connect the cooling chamber, the placement chamber, and the outside. A U-shaped plate is fixedly connected in the cooling chamber. A drive rod is rotatably connected to the U-shaped plate. An axial flow fan blade is fixedly connected to the body of the drive rod. A drive motor for driving the axial flow fan blade is fixedly connected to the U-shaped plate.

[0012] The filtration system is used to filter outside air as it is blown into the cooling chamber.

[0013] Preferably, it further includes: a circulating cooling mechanism for cooling the air by circulating cooling water during the process of outside air being blown into the cooling chamber. The circulating cooling mechanism includes a reciprocating lead screw rotatably connected to the bottom wall of the cooling chamber. A bevel gear set is provided between the upper end of the reciprocating lead screw and the drive rod. A reciprocating lifting plate is threaded onto the reciprocating lead screw. A cooling box is fixedly connected inside the cooling chamber. A piston plate is slidably connected inside the cooling box. A connecting rod is fixedly connected between the piston plate and the reciprocating lifting plate. A serpentine coil is provided above the cooling box. Both ends of the serpentine coil are connected to the interior of the cooling box. A semiconductor refrigeration chip for cooling the cooling water is fixedly connected inside the cooling box.

[0014] Preferably, the filtration mechanism includes a filter screen plate fixedly connected inside the air inlet channel, one end of the drive rod passes through the filter screen plate and is fixedly connected to an L-shaped rod, and a scraping rod that cooperates with the filter screen plate is fixedly connected to the L-shaped rod.

[0015] Preferably, the exhaust duct is equipped with a one-way gas valve.

[0016] Preferably, a strip-shaped limiting groove is provided on the inner wall of the cooling chamber, and the reciprocating lifting plate is slidably connected to the inner wall of the strip-shaped limiting groove in the vertical direction.

[0017] Preferably, liquid check valves are provided at both ends of the serpentine coil where they connect to the interior of the cooling tank.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This utility model achieves efficient cooling by setting up a circulating cooling mechanism. The serpentine coil increases the contact area between the cooling water and the airflow, and the directional circulation of cooling water formed by the reciprocating screw driving the piston plate significantly improves the heat exchange efficiency between the cooling water and the air. At the same time, the semiconductor refrigeration chip in the cooling box continuously cools the circulating cooling water, ensuring that the air entering the placement chamber is always at a low temperature. The low-temperature airflow is accelerated by the ventilation mechanism and flows over the surface of the charging mechanism, which can quickly remove the large amount of heat generated during the charging process, effectively solving the problem of poor heat dissipation of traditional charging piles and their inability to meet the cooling requirements of high-temperature charging mechanisms.

[0020] 2. This utility model, through the installation of a filtration mechanism, effectively filters incoming outside air via a filter screen within the air intake channel, intercepting dust, particulate matter, and other impurities to prevent them from adhering to the surface of the charging mechanism or entering its interior. Simultaneously, the rotation of the drive rod causes the L-shaped rod and scraping rod to rotate synchronously, continuously cleaning the filter screen surface and preventing impurities from accumulating and clogging the filter, thus ensuring the ventilation efficiency of the air intake channel. Through the synergistic effect of filtration and cleaning, the impact of dust on the heat dissipation and charging efficiency of the charging mechanism is effectively avoided, ensuring the stable operation of the charging mechanism.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figures 1 to 5 A new energy charging pile with heat dissipation function includes:

[0034] The charging pile housing 1 has a partition 11 fixedly connected inside the charging pile housing 1. The interior of the charging pile housing 1 is divided into a cooling chamber 12 and a placement chamber 13 by the partition 11. A ventilation channel connecting the cooling chamber 12 and the placement chamber 13 is opened on the partition 11. A charging mechanism 2 is fixedly connected inside the placement chamber 13.

[0035] Specifically, a one-way gas valve is installed inside the exhaust duct 32.

[0036] Ventilation mechanism 3 is installed in cooling chamber 12 and is used to blow outside air into placement chamber 13 to accelerate air circulation around charging mechanism 2. Ventilation mechanism 3 includes air inlet channel 31 and air outlet channel 32 fixedly connected to the outer walls of both sides of charging pile housing 1. Air inlet channel 31 and air outlet channel 32 connect cooling chamber 12, placement chamber 13 and the outside. U-shaped plate 33 is fixedly connected in cooling chamber 12. Drive rod 34 is rotatably connected to U-shaped plate 33. Axial flow fan blade 35 is fixedly connected to the rod of drive rod 34. Drive motor 36 for driving axial flow fan blade 35 is fixedly connected to U-shaped plate 33.

[0037] During the operation of the charging pile, the charging mechanism 2 generates a large amount of heat when charging in the placement chamber 13. At this time, the drive motor 36 is started, and the ventilation mechanism 3 begins to work. The drive motor 36 drives the drive rod 34 to rotate, and the axial flow fan blades 35 on the drive rod 34 rotate together, forming an airflow driving force in the cooling chamber 12. Under the action of the axial flow fan blades 35, outside air enters the cooling chamber 12 through the air inlet channel 31, and flows into the placement chamber 13 through the ventilation channel on the partition 11, accelerating the air circulation speed around the charging mechanism 2, so that the heat on the surface of the charging mechanism 2 is quickly removed; the air carrying heat is discharged to the outside through the exhaust channel 32, and the gas one-way valve inside the exhaust channel 32 can effectively prevent outside air or impurities from flowing back into the placement chamber 13, ensuring the stability of the airflow direction.

[0038] The filter mechanism 4 is used to filter the outside air during the process of blowing outside air into the cooling chamber 12. The filter mechanism 4 includes a filter screen plate 41 fixedly connected to the inside of the air inlet channel 31, one end of the drive rod 34 passes through the filter screen plate 41 and is fixedly connected to an L-shaped rod 42, and a scraping rod 43 that cooperates with the filter screen plate 41 is fixedly connected to the L-shaped rod 42.

[0039] As outside air enters the cooling chamber 12 through the air inlet duct 31, the filter mechanism 4 simultaneously performs its filtering function. The filter screen 41 inside the air inlet duct 31 can intercept dust, particulate matter, and other impurities in the air, preventing these impurities from entering the placement chamber 13 with the airflow and adhering to the surface of the charging mechanism 2. This prevents the charging mechanism 2 from experiencing reduced heat dissipation or contamination of internal components due to impurities. At the same time, when the drive rod 34 rotates, it drives the L-shaped rod 42 passing through one end of the filter screen 41 to rotate synchronously. The scraping rod 43 on the L-shaped rod 42 rotates along with it, continuously scraping the surface of the filter screen 41 to remove impurities adhering to it. This prevents the filter screen 41 from becoming clogged due to impurity accumulation and ensures the ventilation efficiency of the air inlet duct 31.

[0040] The circulating cooling mechanism 5 is used to cool the air by circulating cooling water during the process of blowing outside air into the cooling chamber 12. The circulating cooling mechanism 5 includes a reciprocating screw 51 rotatably connected to the bottom wall of the cooling chamber 12. A bevel gear set 52 is provided between the upper end of the reciprocating screw 51 and the drive rod 34. A reciprocating lifting plate 53 is threadedly connected to the reciprocating screw 51. A cooling box 54 is fixedly connected inside the cooling chamber 12. A piston plate 55 is slidably connected inside the cooling box 54. A connecting rod 56 is fixedly connected between the piston plate 55 and the reciprocating lifting plate 53. A serpentine coil 57 is provided above the cooling box 54. Both ends of the serpentine coil 57 are connected to the inside of the cooling box 54. A semiconductor refrigeration chip for cooling the cooling water is fixedly connected inside the cooling box 54.

[0041] Specifically, a strip-shaped limiting groove is provided on the inner wall of the cooling chamber 12. The reciprocating lifting plate 53 is slidably connected to the inner wall of the strip-shaped limiting groove in the vertical direction, so that the reciprocating screw 51 can only drive the reciprocating lifting plate 53 to move in the vertical direction during rotation, and will not rotate with the reciprocating screw 51.

[0042] Specifically, liquid check valves are provided at both ends of the serpentine coil 57 where they connect to the interior of the cooling box 54.

[0043] To further improve heat dissipation, the circulating cooling mechanism 5 cools the air entering the cooling chamber 12 during ventilation. When the drive rod 34 rotates, it drives the reciprocating screw 51 to rotate synchronously through the bevel gear set 52. Since the reciprocating lifting plate 53 is threadedly connected to the reciprocating screw 51, and the strip-shaped limiting groove on the inner wall of the cooling chamber 12 restricts the movement direction of the reciprocating lifting plate 53, the reciprocating lifting plate 53 will reciprocate and lift in the vertical direction. The reciprocating lifting plate 53 drives the piston plate 55 to slide synchronously up and down within the cooling tank 54 via the connecting rod 56. When the piston plate 55 slides upward, the cooling water in the cooling tank 54 flows into the serpentine coil 57 under pressure through the liquid check valve at one end of the coil. When the piston plate 55 slides downward, the cooling water in the serpentine coil 57 flows back to the cooling tank 54 under pressure through the liquid check valve at the other end of the coil, thus achieving a circulation of cooling water between the cooling tank 54 and the serpentine coil 57. Simultaneously, the thermoelectric cooler within the cooling tank 54 continuously cools the cooling water, ensuring the circulating water remains at a low temperature. When the airflow driven by the axial fan blades 35 flows in the cooling chamber 12, it passes over the surface of the serpentine coil 57 and exchanges heat with the low-temperature serpentine coil 57, causing the air temperature to drop rapidly. The cooled air then enters the placement chamber 13, further enhancing the heat dissipation effect on the charging mechanism 2 and meeting the cooling requirements of the high-temperature charging mechanism during the charging process.

[0044] The functional principle of this utility model can be explained through the following operation methods:

[0045] When the charging pile is running, the charging mechanism 2 generates a lot of heat in the placement chamber 13. At this time, the drive motor 36 starts and drives the drive rod 34 to rotate, triggering the linkage of multiple mechanisms.

[0046] When the drive rod 34 rotates, it drives the axial fan blades 35 to rotate synchronously, forming a directional airflow driving force in the cooling chamber 12. Under the action of this driving force, outside air enters the cooling chamber 12 through the air inlet channel 31, flows into the placement chamber 13 through the ventilation channel on the partition 11, directly accelerates the air circulation speed around the charging mechanism 2, and causes the heat on the surface of the charging mechanism 2 to be quickly trapped. The air carrying the heat is then discharged to the outside through the exhaust channel 32.

[0047] The filter mechanism 4 simultaneously intercepts impurities during ventilation. When outside air enters the air intake channel 31, the filter screen 41 inside the channel intercepts dust, particulate matter, and other impurities in the air, preventing them from entering the placement chamber 13 with the airflow and adhering to the surface of the charging mechanism 2. This prevents the heat dissipation efficiency from decreasing or the internal components from being contaminated due to impurities covering the surface. At the same time, when the drive rod 34 rotates, it drives the L-shaped rod 42 passing through one end of the filter screen 41 to rotate. The scraping rod 43 on the L-shaped rod 42 rotates along with it, continuously scraping and cleaning the surface of the filter screen 41 to remove the attached impurities in a timely manner.

[0048] The circulating cooling mechanism 5 further enhances the heat dissipation effect, cooling the air entering the cooling chamber 12. When the drive rod 34 rotates, the power is transmitted to the reciprocating screw 51 through the bevel gear set 52, causing the reciprocating screw 51 to rotate synchronously. This causes the reciprocating lifting plate 53 to move back and forth vertically, driving the piston plate 55 to slide synchronously up and down within the cooling box 54, achieving directional circulation of cooling water between the cooling box 54 and the serpentine coil 57. Simultaneously, the semiconductor cooling chip inside the cooling box 54 continuously cools the cooling water, maintaining the low temperature of the circulating water. When the airflow driven by the axial fan blades 35 flows within the cooling chamber 12, it flows over the surface of the serpentine coil 57, exchanging heat fully with the low-temperature coil, rapidly reducing the air temperature and enhancing the heat dissipation capacity of the charging mechanism 2, meeting the cooling requirements of the high-temperature charging mechanism during charging.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
