Description

Technical Field

[0001] This utility model relates to the field of vehicle charging pile technology, and in particular to a charging pile temperature control device. Background Technology

[0002] With the increasing popularity of electric vehicles, charging piles, as an important supporting facility for electric vehicles, are receiving more and more attention for their performance and user experience. However, existing charging piles cannot dissipate the heat generated during charging in a timely manner, leading to an increase in the internal temperature of the charging pile, which affects the working efficiency and service life of the charging pile, and may even cause safety accidents. Therefore, there is an urgent need for a charging pile with temperature control to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a charging pile temperature control device to solve the problem that, during the use of existing charging piles, the heat generated during charging cannot be dissipated in time, leading to an increase in the internal temperature of the charging pile, which affects the working efficiency and service life of the charging pile.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a charging pile temperature control device, comprising a body and a heat dissipation component disposed above the body, with ventilation holes on two sides of the body, the heat dissipation component comprising a moving platform, a cooling fan and a cooler, an air inlet and a guide groove on the top of the body, the moving platform sliding along the guide groove, the bottom of the moving platform being an open surface, the cooling fan disposed on the moving platform, and the cooler disposed on the moving platform and facing the air inlet.

[0005] Furthermore, the top of the mobile platform is provided with a ventilation window, which is located above the cooling fan.

[0006] Furthermore, a waterproof cover is provided above the mobile platform, which is located above the ventilation window and covers the ventilation window.

[0007] Furthermore, the movable stage has limiting sliders on both sides, and a fixing hole is opened at the outer end of the limiting slider. The guide groove has a side ear on the outer side, and a fixing pin is provided on the side ear. The fixing pin passes through the side ear and is inserted into the fixing hole, thereby fixing the movable stage.

[0008] Furthermore, the limiting slider is provided with a limiting groove, and the inner side of the guide groove is provided with a limiting pin that extends into the limiting groove.

[0009] Furthermore, the outer end of the mobile platform is provided with a downwardly extending grip plate.

[0010] Furthermore, the air conditioner includes a condenser, an evaporator, and a compressor. The condenser is located above the movable platform, the evaporator is located below the cooling fan, and the compressor is connected to the condenser and the evaporator.

[0011] Furthermore, the device also includes a display screen, operation buttons, and a charging gun.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This temperature control device integrates the cooling fan and air cooler onto a movable platform that slides along a guide groove on the top of the unit. This allows for easy and thorough cleaning of the entire cooling assembly (including the fan and air cooler) by simply pulling it out of the upper part of the unit during routine maintenance. This significantly improves the convenience and efficiency of cleaning and maintenance, solving the problem of traditional built-in cooling devices being difficult to clean thoroughly, leading to decreased heat dissipation performance. Simultaneously, when the movable platform is reset during operation, the cooling fan faces the air intake of the unit. The cool air generated by the air cooler is precisely and efficiently forced into the unit by the fan, exchanging heat with the heat generated by the equipment. Combined with the convection channels formed by the ventilation holes on the side walls of the unit, this achieves rapid, proactive, and uniform cooling of the core equipment inside the charging pile through a dual cooling system of "direct airflow + forced convection." This significantly improves temperature control efficiency, effectively ensuring the stable operation of the electronic components inside the charging pile at a suitable temperature, extending the equipment's lifespan, and enhancing operational safety.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0023] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0024] like Figures 1 to 6As shown, this utility model provides a charging pile temperature control device, including a body 1 and a heat dissipation assembly 2 disposed above the body 1. The body 1 has ventilation holes 11 on two sides. The heat dissipation assembly 2 includes a movable platform 21, a cooling fan 22, and a cooler 23. The top of the body 1 has an air inlet 12 and a guide groove 13. The movable platform 21 slides along the guide groove 13. The bottom of the movable platform 21 is open. The cooling fan 22 and the cooler 23 are disposed on the movable platform 21 and face the air inlet 12. This utility model's charging pile temperature control device integrates the cooling fan 22 and the cooler 23 onto a movable platform 21 that can slide along the guide groove 13 on the top of the body 1, making routine maintenance easy by simply pulling the entire heat dissipation assembly 2 (including the fan and cooler 23). By directly and thoroughly cleaning the surface and internal dust of the charging pile from the area above the body 1, the convenience and efficiency of cleaning and maintenance are greatly improved. This solves the problem of traditional built-in heat dissipation devices being difficult to clean thoroughly, which leads to a decrease in heat dissipation performance. At the same time, when the moving platform 21 is reset in the working state, the cooling fan 22 is directly facing the air inlet 12 of the body 1. The cold air generated by the air cooler 23 is precisely and efficiently forced into the body 1 by the fan, and undergoes a strong heat exchange with the heat generated by the equipment. Combined with the convection channel formed by the vents 11 on the side wall of the body 1, a dual cooling of "direct air blowing + forced convection" is achieved for the core equipment inside the charging pile, which is fast, active and uniform. This significantly improves the temperature control efficiency, thereby effectively ensuring that the electronic components inside the charging pile operate stably at a suitable temperature, extending the service life of the equipment and improving operational safety.

[0025] The top of the mobile platform 21 is provided with a ventilation window 211, which is located above the cooling fan 22. By opening a ventilation window 211 on the top of the mobile platform 21 directly above the cooling fan 22, a vertical air intake channel is constructed. External cold air is efficiently drawn in by the fan through the ventilation window 211, mixed with the cold air generated by the air conditioner 23, and then precisely blown into the air intake hole 12 of the body 1 through the bottom open surface, thereby improving the air intake efficiency.

[0026] A waterproof cover 212 is also provided above the mobile platform 21. The waterproof cover 212 is located above the ventilation window 211 and covers the ventilation window 211. The addition of the waterproof cover 212 covering the ventilation window 211 forms a sloping rain-guiding structure. Rainwater slides down the cover surface and cannot enter the ventilation window 211. While ensuring the air intake, it also achieves rain protection, avoiding the risk of electrical short circuits or fan corrosion caused by rainwater seepage, and extending the service life of the equipment.

[0027] The movable platform 21 has limiting sliders on both sides, and a fixing hole 214 is opened on the outer end of the limiting slider. The guide groove 13 has a side ear 14 on the outer side, and a fixing pin is provided on the side ear 14. The fixing pin passes through the side ear 14 and is inserted into the fixing hole 214, thereby fixing the movable platform 21. The limiting slider and the fixing pin of the side ear 14 are plugged into a locking mechanism. When the movable platform 21 is pushed to the working position, the fixing pin passes through the side ear 14 and is embedded in the fixing hole 214 of the slider, forming a mechanical rigid constraint. This ensures that the direction of the cold air jet does not deviate under the high-frequency vibration of the fan. At the same time, it achieves one-second locking and unlocking without the need for electric drive, taking into account both the convenience of operation and the stability under extreme working conditions.

[0028] The limiting slider is provided with a limiting groove 215, and the inner side of the guide groove 13 is provided with a limiting pin 216 extending into the limiting groove 215; the limiting groove 215 and the limiting pin 216 in the guide groove 13 form a nested sliding pair. When the moving platform 21 slides, the limiting pin 216 is constrained in the groove throughout the entire process, completely eliminating the risk of derailment. This not only prevents the equipment from falling due to violent pulling during maintenance, but also ensures that the cooling fan 22 automatically aligns with the air inlet 12 after reset.

[0029] The outer end of the mobile platform 21 is provided with a downwardly extending grip plate 24; the downwardly extending grip plate 24 integrated on the outer side of the mobile platform 21 provides a lever application point, making it convenient for maintenance personnel to pull out the mobile platform 21.

[0030] The air conditioner 23 includes a condenser 231, an evaporator 232, and a compressor 234. The condenser 231 is located above the moving platform 21, and the evaporator 232 is located below the cooling fan 22. The compressor 234 connects the condenser 231 and the evaporator 232. The working principle of the air conditioner 23 is based on a refrigeration cycle: the compressor 234 drives the refrigerant to circulate in a closed system. The high-temperature, high-pressure gaseous refrigerant first enters the condenser 231 above the moving platform 21, where it releases heat and liquefies into a high-pressure liquid through natural convection and the auxiliary airflow of the cooling fan 22. After the liquid refrigerant flows through the expansion valve to reduce its pressure, it enters the evaporator 232 located directly below the cooling fan 22. Here, it absorbs the heat introduced from inside the machine body 1 and rapidly vaporizes, causing the air temperature to drop sharply to 5-10°C. The generated low-temperature gas is forced into the air inlet 12 of the machine body 1 by the cooling fan 22 to achieve rapid cooling. The condenser 231 is placed in an independent heat dissipation area on the top of the moving platform 21 to avoid the heat accumulation of the machine body 1 from affecting the condensation efficiency, while the evaporator 232 is close to the fan air inlet to achieve zero-delay delivery of cold air. The structure of the air conditioner 23 is the same as that of existing vehicle refrigeration equipment, and its components can be purchased on the market. This utility model will not be described in detail here.

[0031] The body 1 also includes a system control panel 3, a display screen 31, operation buttons 32, and a charging gun 4; the temperature control device is integrated with the system control panel 3, the display screen 31, and other core components of the charging pile in the same body 1, realizing deep integration and coordination of charging operation, status monitoring, and temperature protection.

[0032] The body 1 is equipped with a temperature sensor 5, which transmits signals to the system operation board 3. The signals from the temperature sensor 5 control the cooling fan 22 and the air conditioner 23. The temperature sensor 5 monitors the internal temperature of the body 1 in real time and feeds it back to the system operation board 3, triggering a graded control strategy: the fan starts at 35°C, the air conditioner 23 is activated at 45°C, and the system stops when the temperature drops to 30°C, thus saving energy through segmented operation.

[0033] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
