Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile with good heat dissipation performance. Background Art

[0002] Electric vehicle charging piles are devices that provide power supply for electric vehicles. They connect to the power grid, convert AC power into DC power or directly output AC power to charge electric vehicle batteries. Charging piles come in different types and powers and can be installed in public areas, parking lots, residential areas, etc. Their convenient and efficient charging services have promoted the popularization of electric vehicles, helped green travel, and reduced environmental pollution and dependence on traditional fuels.

[0003] The charging pile mainly consists of charging modules, control circuits and other structures. When charging, the current passing through the charging module and lines will generate heat, which will increase the temperature of the charging pile surface. At the same time, the control circuit will also have a certain power loss converted into heat during operation. If this heat is not dissipated in time, it will affect the performance and life of the charging pile, so a heat dissipation system is needed to maintain it working within the appropriate temperature range.

[0004] The heat dissipation structure of existing charging piles often dissipates heat for the entire charging pile, while the heat generated by various components inside the charging pile is different when running. For example, when the transformer is running at high load, its heat generation is relatively large, and the heat generation of the rectifier is usually smaller than that of the transformer. The controller is mainly responsible for monitoring and managing the charging process, so the heat generation is small when working. Therefore, when the heat dissipation structure dissipates heat for the charging pile, it cannot dissipate heat specifically for the components with the highest temperature in the charging pile. As a result, the heat of key parts cannot be dissipated quickly during continuous operation, which may eventually cause damage to the components due to heat accumulation, affecting the normal use of the charging pile.

The oil outlet of the heat pipe 14 is fixedly provided with a second oil delivery pipe 15, and the oil outlet of the second oil delivery pipe 15 passes through the oil tank 11 and extends to the inside of the oil tank 11. The charging pile with good heat dissipation cools the gas inside the cold air box 5 through the refrigeration component. The cooled gas enters the interior of the exhaust pipe 6 and contacts the charging pile component group 3 through the through hole 7, dissipating heat to the charging pile component group 3 as a whole, and at the same time starting the oil The pump 12 inputs the heat transfer oil from the oil tank 11 into the first oil pipe 13. When the heat transfer oil enters the cold air box 5, the cold air inside the cold air box 5 will exchange heat with the heat transfer oil through the first oil pipe 13, thereby reducing the temperature of the heat transfer oil. The low-temperature heat transfer oil enters the heat transfer pipe 14 to dissipate heat specifically for the component with the highest temperature on the charging pile component group 3. This device can dissipate heat for the charging pile as a whole, thereby maintaining each component working within an appropriate temperature range, and focusing on dissipating heat for the component with the highest temperature, thereby effectively preventing component overheating failure and increasing the service life of the charging pile.

[0024] Specifically, the refrigeration component includes a semiconductor refrigeration plate 9 fixedly arranged on the top of the cold air box 5. The number of the semiconductor refrigeration plates 9 is multiple, and the multiple semiconductor refrigeration plates 9 are distributed linearly. The cold end of the semiconductor refrigeration plate 9 is located inside the cold air box 5, and the hot end of the semiconductor refrigeration plate 9 is located outside the cold air box 5. The hot end of the semiconductor refrigeration plate 9 is fixedly provided with a heat dissipation fin 10. The gas inside the cold air box 5 is cooled by the semiconductor refrigeration plate 9. The heat dissipation speed of the hot end of the semiconductor refrigeration plate 9 can be accelerated through the heat dissipation fin 10, thereby reducing the impact on the cooling effect of the cold end of the semiconductor refrigeration plate 9.

[0025] Specifically, a fixing plate 16 is fixedly provided on the surface of the box body 1, and a fixing hole 17 is opened on the surface of the fixing plate 16. A fixing device such as a ground nail is inserted into the fixing hole 17 to fix the fixing plate 16 in the installation position, thereby fixing the charging pile to prevent the charging pile from being easily moved. A sun visor 2 is fixedly provided on the top of the box body 1. The sun visor 2 is made of fiberglass. The fiberglass has good sunshade performance and is corrosion-resistant and high-strength.

[0027] During use: start the air pump 8 to draw the gas into the interior of the cold air box 5, and start the semiconductor refrigeration plate 9 to cool the gas inside the cold air box 5 through the semiconductor refrigeration plate 9.

When entering the first oil pipe 13 located in the cold air box 5, the cold air inside the cold air box 5 will exchange heat with the thermal oil through the first oil pipe 13, thereby reducing the temperature of the thermal oil surface. The thermal oil after heat dissipation enters the interior of the heat pipe 14 through the first oil pipe 13, and dissipates the heat of the component with the highest temperature on the charging pile component group 3 through the heat pipe 14. Then the thermal oil enters the interior of the oil tank 11 through the second oil pipe 15.

[0028] To sum up, the charging pile with good heat dissipation performance cools down the gas inside the cold air box 5 through the refrigeration component. The cooled gas enters the exhaust pipe 6 and contacts the charging pile component group 3 through the through hole 7, thereby dissipating the heat of the charging pile component group 3 as a whole. At the same time, the oil pump 12 is started to input the thermal oil in the oil tank 11 into the first oil pipe 13. When the thermal oil enters the cold air box 5, the cold air inside the cold air box 5 will exchange heat with the thermal oil through the first oil pipe 13, thereby reducing the temperature of the thermal oil. The low-temperature thermal oil enters the heat pipe 14 to dissipate heat specifically for the component with the highest temperature on the charging pile component group 3. The device can dissipate heat for the charging pile as a whole, thereby maintaining each component working within an appropriate temperature range, and focusing on dissipating heat for the component with the highest temperature, thereby effectively preventing component overheating failure and increasing the service life of the charging pile.
