Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging, and more specifically, to a heat dissipation type electric vehicle charger. Background Art

[0002] Electric vehicle charging piles refer to chargers that provide charging services for electric vehicles. Charging piles are mainly divided into floor-standing charging piles and wall-mounted charging piles, and mainly adopt charging methods based on time, electricity metering, and amount metering. Charging piles can be fixed on the ground or walls, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. Most charging piles are public charging piles, which generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charging pile to perform corresponding charging methods, charging time, and cost data printing. The charging pile display can display data such as charging amount, cost, and charging time.

[0003] In actual scenarios, electric vehicle charging piles are generally located outdoors. During actual charging, the electrical components in the charging pile body will generate a lot of heat. If the heat cannot be dissipated quickly, it will have a negative impact on the charging efficiency and will also damage the electrical components of the charger itself, affecting its service life. Therefore, it is necessary to design an efficient heat dissipation module for electric vehicle chargers to better serve users. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-2 As shown, the utility model provides a heat dissipation type electric vehicle charger, comprising a fixed charging pile 1 and a heat dissipation mechanism;

[0021] The fixed charging pile 1 includes a matching fixed base 2 and a pile body 3, wherein the fixed base 2 is fixed to the ground, and the pile body 3 includes a protective shell 4 and a plurality of charger components 5 accommodated in the center of the pile body 3.

[0022] like Figure 1As shown, the heat dissipation mechanism includes a water tank 6, an electric water pump 7, a water cooling head 8 and a plurality of water pipes 9. The water tank 6 is arranged at one side of the fixed charging pile 1. The water tank 6 contains cooling water. The water inlet pipe of the electric water pump 7 extends into the bottom of the water tank 6. The water outlet pipe of the electric water pump 7 is connected to the water inlet end of the water cooling head 8 through the water pipe 9. The water outlet end of the water cooling head 8 is introduced into the water tank 6 through the water pipe 9. The water cooling head 8 is placed between the charger components 5. The box cover of the water tank 6 is fixedly connected to an ice maker 10. The water intake pipe of the ice maker 10 extends into the bottom of the water tank 6. The ice outlet of the ice maker 10 is arranged inside the water tank 6.

[0023] The water cooling head 8 can be placed on the side of the electrical device that is most prone to high temperature failure, so as to achieve a more precise cooling effect.

[0024] Specifically, the number of water cooling heads 8 is at least one. When the number of water cooling heads 8 exceeds one, the water outlet of the water cooling head 8 that feeds water first is connected to the water inlet of the water cooling head 8 that feeds water later through a water pipe 9. That is to say, multiple water cooling heads 8 can be arranged in a fixed charging pile 1. The water cooling heads 8 can be placed next to components that need rapid heat dissipation, so that these components can be accurately cooled, so that the overall heat dissipation effect is better, ensuring the smooth charging of the charger.

[0025] The working principle and use process of the heat dissipation type electric vehicle charger of the present invention are as follows: when the charger is actually used for charging, the real-time temperature of the charger component 5 is monitored by a temperature sensing device. When heat dissipation is required, the electric water pump 7 and the ice maker 10 are started. Starting the ice maker 10 can make ice cubes to cool down the water temperature in the water storage tank 6. Starting the electric water pump 7 can pump the water in the water storage tank 6 into the water pipe 9 and the water cooling head 8. When water flows through the water pipe 9 and the water cooling head 8, the charger component 5 can be cooled to achieve efficient heat dissipation of the charger component 5. In particular, the water passing through the water cooling head 8 is treated with ice cubes at low temperature, so its cooling efficiency can be greatly increased, and the overall heat dissipation effect of the charger is better.

[0026] It should be noted that the heat dissipation mechanism is provided with an independent power supply. When heat dissipation is required, the ice-making frequency and ice-making amount of the ice-maker 10 can be adjusted according to the temperature value obtained by the temperature sensing device, thereby achieving low-temperature control of the water temperature, improving the heat dissipation efficiency, and reducing the possibility of damage to the charger component 5.

[0027] As an embodiment of the present utility model, a cooling water pipe 11 is further arranged in the internal space of the protective housing 4. The cooling water pipe 11 is attached to the outside of the charger assembly 5. The water inlet end of the cooling water pipe 11 is connected to the water outlet end of the last water-inlet water cooling head 8, and the water outlet end of the cooling water pipe 11 is connected to the water pipe 9 that conveys water to the water storage tank 6. The cooling water pipe 11 is a continuous S-shaped water pipe, and the pipe wall of the cooling water pipe 11 is a flexible water pipe.

[0028] like Figure 2 As shown, the cooling water pipe 11 can be used to cool and dissipate heat within the protective housing 4 over a large area, thereby improving the overall heat dissipation efficiency. Furthermore, the cooling water pipe 11 is set to be S-shaped, which can increase the contact area and improve the heat dissipation effect.

[0029] As an embodiment of the present invention, a heat preservation layer is arranged on the outside of the water tank 6, which can prevent the water in the water tank 6 from being quickly assimilated by the external temperature and reduce energy waste. The water tank 6 is an underground water tank 6, which can reduce the occupied space and the soil temperature is lower, which is conducive to reducing the waste of temperature energy.

[0030] As an embodiment of the utility model, the water tank 6 is provided with a mixing mechanism, which includes a rotating motor 12, a rotating shaft 13, a horizontal connecting rod 14, and a stirring blade 15. The fixed part of the rotating motor 12 is fixedly connected to the outer side of the tank cover of the water tank 6, and the tank cover of the water tank 6 is penetrated with an opening. The top end of the rotating shaft 13 passes through the opening and is fixedly connected to the rotating part of the rotating motor 12, the bottom end of the rotating shaft 13 is fixedly connected to the middle part of the horizontal connecting rod 14, and the top end of the stirring blade 15 is vertically fixedly connected to the two ends of the horizontal connecting rod 14, so that the water in the water outlet tank can be quickly mixed. When the ice maker 10 is working, the water temperature in the water tank can be quickly reduced.

[0031] As an embodiment of the utility model, a shade and rainproof awning is arranged on the top of the fixed charging pile 1, and the shade and rainproof awning includes a roof plate 16 and a plurality of support rods 17. The top ends of the support rods 17 are fixedly connected to the bottom surface of the roof plate 16, and the bottom ends of the support rods 17 are fixedly connected to the top of the protective shell 4, which can provide shade and rain protection for the fixed charging pile 1, and in hot weather, can reduce the heating effect of the sun on the fixed charging pile 1.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
