Description

Technical Field

[0001] The utility model belongs to the technical field related to charging piles, and in particular relates to a liquid cooling device for a charging pile. Background Art

[0002] Charging pile liquid cooling equipment refers to the use of liquid cooling design in the design of the charging pile to improve charging efficiency and the heat dissipation capacity of the equipment. This technology is particularly suitable for high-power fast charging scenarios because in these scenarios, the heat generated by the charging equipment increases significantly. Traditional air cooling methods cannot meet the heat dissipation requirements. Liquid cooling equipment is used in conjunction with heat dissipation to effectively dissipate heat from the charging equipment. However, it still has the following disadvantages in actual use:

[0003] When the charging pile liquid cooling equipment is working, the working range of the liquid cooling equipment usually overlaps with the working range of the charging pile internal circuit. As a result, the heat generated by the liquid cooling equipment is transferred to the working range during the working process, which can easily cause the temperature of the charging equipment to be too high.

[0004] When the liquid cooling equipment of the charging pile is working, it is cooled directly by the cooling equipment. During the cooling process, it is cooled directly by the radiator. During the cooling process, the cooling operation is only performed through the radiator. During the cooling process, in order to reduce the temperature to a suitable level, a greater heat dissipation power is required, and the energy consumption is higher. Utility Model Content

[0005] The purpose of the utility model is to provide a charging pile liquid cooling device. By arranging a charging pile shell, a radiator, a circulation pump and a fixing frame, the utility model solves the problem that the temperature of the charging equipment is high during operation due to insufficient separation between the charging pile liquid cooling device and the charging equipment, and the energy consumption is high when cooling is performed only through the radiator during the heat dissipation process.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a charging pile liquid cooling device, comprising a charging pile shell, a radiator, a circulation pump and a fixing frame, wherein the inner bottom of the charging pile shell is fixed with a fixing frame, the top of the fixing frame is fixed with a circulation pump, the input end of the circulation pump is fixedly connected with a discharge pipe, the top end of the discharge pipe is fixedly connected with a storage tank, a radiator is fixed at the lower part of one side of the inner wall of the charging pile shell, a fixed cavity is provided between the storage tank and the radiator, a partition is fixed at the lower part of the inner wall of the charging pile shell, a fixed opening is provided on the partition corresponding to the position of the fixed cavity, the fixed cavity is fixed in the fixed opening, when working, the radiator, the circulation pump and the fixing frame are accommodated therein by the charging pile shell, the coolant circulating in the circulation pump is circulated and cooled by the radiator, the coolant is transported to the radiator by the circulation pump, and heat is dissipated in cooperation, and the circulation pump is supported in the charging pile shell by the fixing frame.

[0008] Furthermore, ventilation holes are provided in a rectangular array on both sides of the charging pile shell below the partition, and a fixing sleeve is fixedly connected to the bottom end of the charging pile shell. When the charging pile shell is working, ventilation is carried out through the ventilation holes.

[0009] Furthermore, the output end of the radiator is fixedly connected to an output pipe, and the input end of the radiator is fixedly connected to an input pipe. When the radiator is working, the coolant is transported into it through the input pipe and discharged through the output pipe.

[0010] Furthermore, the storage tank is fixed at the bottom of the partition, the output end of the storage tank is fixedly connected to a return pipe, and the end of the return pipe away from the storage tank is fixedly connected to the output pipe. When the storage tank is working, the coolant flows back into it through the return pipe.

[0011] Furthermore, the output end of the circulation pump is fixedly connected to a fixed pipe, the top end of the fixed pipe is fixedly connected to the bottom of the fixed cavity, the bottom end of the fixed cavity is fixedly connected to the edge away from the fixed pipe with a guide pipe, and one end of the guide pipe away from the fixed cavity is fixedly connected to the input pipe. When the circulation pump is working, the coolant pumped therein is transported to the fixed cavity through the fixed pipe.

[0012] Furthermore, the top of the fixed cavity is fixedly connected with three connection nozzles, the bottom of the storage tank is fixedly connected with a joint, and the fixed cavity is connected with the end of the cooling liquid delivery pipeline of the cooling equipment through the connection nozzles.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem of insufficient separation between the liquid cooling device of the charging pile and the charging device, which causes the high temperature of the charging device during operation, by arranging the charging pile shell and the radiator. After the structural setting in the charging pile shell is completed, the partition separates the radiator, the circulation pump and the fixing frame in the charging pile shell and the working circuit above it. When working, the partition is connected with the structure that needs heat dissipation in the charging pile through the connecting nozzle, so that after the heat dissipation structure is connected and the heat is dissipated, the coolant enters the fixed cavity again to cool the equipment that needs cooling in the charging pile. When working, the liquid cooling device of the charging pile and the charging device can be well separated to prevent the high temperature of the charging device during operation.

[0015] The utility model solves the problem of high energy consumption of cooling only through the radiator during the heat dissipation of the charging pile liquid cooling device by arranging a charging pile shell, a radiator, a circulation pump and a fixing bracket. The circulation pump is started to generate negative pressure through the circulation pump. At this time, the coolant is first transported to the circulation pump through the discharge pipe, and is pumped into the fixed pipe through the circulation pump, and is transported to the fixed cavity through the fixed pipe, and is connected with the charging device through the connecting nozzle on the top of the fixed cavity. After cooling the charging device, it is transported to the guide pipe, and then transported to the input pipe through the guide pipe. After being transported to the radiator through the input pipe for heat dissipation, it is transported to the return pipe through the output pipe, and returns to the storage tank through the return pipe to perform a cooling cycle of the coolant. At the same time, the air discharged from the radiator will generate negative pressure under the partition under the charging pile shell, and enter the air through the ventilation holes away from the radiator. The air passing through the charging pile shell passes through the storage tank and further cools the storage tank. In the heat dissipation process of the charging pile liquid cooling device, the storage tank can be used for cooling, and the energy consumption of coolant cooling is lower.

A fixed opening 104 is provided at the position corresponding to the partition 103 and the fixed cavity 306. The fixed cavity 306 is fixed in the fixed opening 104, so that the connecting nozzle 307 on the fixed cavity 306 can be connected to the cooling equipment in the charging pile, so that the structure in the charging pile is cooled.

[0026] Specifically, ventilation holes 102 are provided on both sides of the charging pile shell 1 below the partition 103 in a rectangular array.
