AI Technical Summary
The existing charging piles have slow and uneven heat conduction of the coolant, which makes them prone to water ingress, resulting in poor cooling effect and increased operating costs. The air inlet and outlet are also prone to rainwater and dust, affecting the safe use and lifespan of the charging piles.
The charging pile adopts a liquid-cooled circulation heat dissipation design. By installing vortex components in the serpentine channel, the flow rate of the coolant is increased. An air vent is set between the liquid-cooling cavity and the mounting cavity to prevent dust and rainwater from entering. The vortex components generate vortices in the serpentine channel to increase the mixing and heat conduction effect of the coolant. At the same time, heat sinks and fans are set on the top of the liquid-cooling cavity to enhance heat dissipation.
Without increasing the power of the water pump, the flow rate and heat conduction of the coolant are improved, the service life of the charging device is extended, dust and rainwater are prevented from entering, and the heat dissipation effect and the safety of the charging pile are improved.

Abstract
Description
Technical Field
[0001] This utility model relates to a charging pile, and more particularly to a liquid-cooled circulating heat dissipation type charging pile. Background Technology
[0002] Charging stations, as supporting infrastructure for electric vehicles, provide charging services and contribute to environmental protection and sustainable development. At the same time, the use of charging stations facilitates the widespread adoption of electric vehicles, thereby reducing dependence on fossil fuels, lowering carbon emissions, and benefiting environmental protection.
[0003] In the prior art, utility model patent application number CN202420878944.8 discloses a high-power liquid-cooled charging pile, including a casing and a top cover. A vertical plate is installed inside the casing, and a heat exchange plate is provided on one side of the vertical plate. A serpentine channel is formed inside the heat exchange plate. A liquid cooling unit is provided inside the top cover, and the serpentine channel is connected to the liquid cooling unit. Air inlets are respectively opened on the left and right side walls of the casing, and an air outlet is opened on one side of the top cover. A fan is provided at the air outlet, and the input end of the fan is connected to the interior of the top cover. The combination of air cooling and liquid cooling inside the casing enhances the heat dissipation effect.
[0004] However, in the aforementioned technologies, the liquid cooling unit mainly cools the internal equipment of the casing through a serpentine channel. Due to the slow heat propagation in the coolant, during the cooling process in the camera channel, the coolant temperature is higher near the heat source and lower further away from the heat source on the same cross-section. This results in insufficient heat absorption and poor cooling effect. If the cooling effect needs to be improved, the power of the water pump needs to be increased to increase the flow rate of the coolant, but this will increase the operating cost. In addition, in the aforementioned technologies, rainwater and dust will be drawn into the air inlet and outlet, which is detrimental to the safe use of the charging pile and will reduce the service life of the charging pile.

[0023] This utility model proposes a liquid-cooled circulating heat dissipation type charging pile.
[0024] like Figures 1 to 2 As shown in one embodiment of this utility model, the liquid-cooled circulating heat dissipation charging pile includes a cabinet 1. The cabinet 1 includes an upper liquid-cooling cavity 2 and a lower mounting cavity 3 for installing a charging device. A liquid-cooling device 21 is installed in the liquid-cooling cavity 2. A horizontal plate is provided in the mounting cavity 3. A heat exchange plate 31 is installed on each horizontal plate. The heat exchange plate 31 is provided with a serpentine channel 32 for transporting coolant. The serpentine channel 32 is connected to the liquid-cooling device 21. Multiple vortex components 4 are installed in the serpentine channel 32 to generate vortices and increase flow velocity. Ventilation openings are provided on opposite sides of the liquid-cooling cavity 2 away from the mounting cavity 3. A fan 7 is installed at one of the ventilation openings.
[0025] The liquid cooling device 21 is existing technology and will not be described in detail here. The serpentine channel 32 can be set inside the heat exchange plate 31 or on the surface of the heat exchange plate 31, that is, the hose is fixed on the surface of the heat exchange plate 31. The vortex assembly 4 structure can include a tubular column and a cone. Vortex fan blades are provided on the side wall of the cone. Support plates 412 are provided at both ends of the tubular column. The support plates 412 are provided with rotating grooves 413. Rotating columns 423 are provided at both ends of the cone. The cone is installed in the tubular column and the rotating columns 423 are embedded in the rotating grooves 413.
[0026] In this embodiment, the charging device and the liquid cooling device 21 are isolated by the liquid cooling cavity 2 and the mounting cavity 3, and the air vent is set on the liquid cooling cavity 2 to prevent rainwater and dust from entering the mounting cavity 3, thereby increasing the service life of the charging device inside the mounting cavity 3. Inside the mounting cavity 3, a vortex component 4 is installed in the serpentine channel 32 of the heat sink to generate vortices and increase the flow rate. This causes the coolant in the serpentine channel 32 to generate vortices, increasing the flow rate and making the coolant fully stirred and mixed, thereby increasing the heat conduction effect of the coolant. This increases the heat dissipation effect without increasing the power of the water pump. At the same time, the liquid cooling device 21 is set at the upper end of the mounting cavity 3, and the heat rises directly to the air, driving the air at the bottom of the liquid cooling cavity 2 to form an airflow. This prevents the hot airflow from heating the mounting cavity 3, and the airflow formed can reduce the temperature of the charging device inside the mounting cavity 3 to a certain extent.
[0027] Preferably, such as Figures 3 to 4 As shown, the vortex assembly 4 includes a first tubular column 41 and a second tubular column 42. The first tubular column 41 has a plurality of first spiral grooves 411 on its inner side, and the second tubular column 42 has a second spiral groove 421 on its inner side. The second tubular column 42 is embedded in the first tubular column 41 and rotatably connected to the first tubular column 41. The rotation directions of the first spiral grooves 411 and the second spiral grooves 421 are aligned. When water flows through the second tubular column 42, the water flows through the second spiral grooves 421, generating a torque on the second tubular column 42, causing the second tubular column 42 to rotate. This causes the second column 42 to rotate and generate vortices. Similarly, the first tubular column 41 also generates vortices through the first spiral grooves 411, further increasing the rotation speed of the second tubular column 42, increasing the vortex intensity, and fully stirring the coolant near the vortex assembly 4, increasing the heat conduction speed and flow rate, and further increasing the heat dissipation effect.
[0028] Preferably, such as Figure 4 As shown, support plates 412 are fixed at both ends of the first tubular column 41. The support plates 412 span across the ends of the first tubular column 41 and are narrower than the diameter of the first tubular column 41. Rotating grooves 413 are provided in the middle of both support plates 412. Support bars 422 are provided at both ends of the second tubular column 42. Similar to the support plates 412, rotating columns 423 are provided on opposite sides of the two support bars 422. When the second tubular column 42 is installed on the first tubular column 41, the rotating columns 423 are respectively embedded in the rotating grooves 413. When the coolant passes through the second tubular column 42, the second tubular column 42 rotates relative to the rotating columns 423.
[0029] Preferably, a plurality of agitating blocks 424 are fixedly provided on the inner side of the second tubular column. The agitating blocks 424 are all located in a place that avoids the second spiral groove 421, or they can be set in the spiral groove to further enhance the agitation effect on the water flow and make the coolant fully mixed.
[0030] Preferably, the heat dissipation end of the liquid cooling device 21 is located at the top of the liquid cooling cavity 2 and abuts against the top of the cabinet 1. Several heat dissipation fins 5 are installed on the upper end of the cabinet 1. A cooling fan 6 is installed at one end of the heat dissipation fins 5 to further increase the heat dissipation effect on the liquid cooling cavity 2 and prevent the liquid cooling from being transferred to the mounting cavity 3 due to poor heat dissipation effect of the liquid cooling cavity 2, which would affect the heat dissipation of the charging device in the mounting cavity 3. In addition, the external heat dissipation fins 5 can use self-heating air for heat dissipation, saving energy.
[0031] Specifically, the working principle and usage process of this utility model are as follows: The charging device and the liquid cooling device 21 are isolated by the liquid cooling cavity 2 and the mounting cavity 3, and the air vent is set on the liquid cooling cavity 2 to prevent rainwater and dust from entering the mounting cavity 3, thereby increasing the service life of the charging device inside the mounting cavity 3. Inside the mounting cavity 3, a vortex component 4 for generating vortices and increasing the flow rate is installed in the serpentine channel 32 of the heat sink, so that the coolant in the serpentine channel 32 generates vortices, increases the flow rate, and at the same time, the coolant is fully stirred and mixed, increasing the heat conduction effect of the coolant, thereby increasing the heat dissipation effect without increasing the power of the water pump.
[0032] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
