Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile with uniform heat dissipation function. Background Technology

[0002] Charging piles are the core energy replenishment equipment for new energy vehicles. Charging piles charge the batteries of new energy vehicles through conduction or induction. Charging piles can be divided into two categories: public charging piles and private charging piles. According to the charging power, they can be divided into AC slow charging piles and DC fast charging piles.

[0003] For example, the patent with authorization announcement number CN220947611U describes a charging pile with uniform heat dissipation function. It uses two heat sinks to dissipate heat from the charging unit, and then uses an exhaust fan to draw out the hot air from inside the charging box to achieve the effect of heat dissipation for the charging unit. Then, a water circulation system consisting of a water tank, a circulating pump, a cooling pipe, and a circulation pipe is used to dissipate the heat absorbed by the heat sinks, thereby improving the heat dissipation efficiency and allowing the heat inside the charging box to be quickly discharged, avoiding damage to the electronic components inside the charging pile, and thus improving the service life of the charging pile.

[0004] The existing technology has the following problems: 1. In existing technical solutions, when the charging pile is continuously cooled for a long time, a large temperature difference will form between the inlet and outlet of the cooling pipe. This significant temperature difference can easily cause uneven cooling in different areas of the charging pile, which may damage the charging pile itself and affect its normal operation and service life.

[0005] 2. Existing technical solutions meet ventilation requirements by opening air inlets. However, in practical applications, the continuous ventilation through these inlets can become a channel for impurities to enter. Dust, debris, and other pollutants in the air can easily enter the pile body with the airflow, potentially clogging internal pipes or components, accelerating component wear, and ultimately causing equipment damage, increasing maintenance costs and downtime risks.

[0006] Based on this, a charging pile with uniform heat dissipation function is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0007] The purpose of this invention is to provide a charging pile with uniform heat dissipation function to solve the problems in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A charging pile with uniform heat dissipation function includes a housing, an operation screen on the surface of the housing, a charging cable on the side of the housing, a charging gun at the end of the charging cable, a storage seat for storing the charging gun on the surface of the housing, a battery for charging inside the housing, and a high-efficiency heat dissipation mechanism on the housing, the high-efficiency heat dissipation mechanism including a cooling box located inside the housing, and a ventilation frame at the ventilation holes of the housing.

[0009] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a cooling fan is provided on the side of the cooling box, the air outlet of the cooling fan is connected to the outside air through a ventilation hole, and a plurality of cooling pipes are connected to the surface of the cooling box, the cooling pipes being in contact with the surface of the battery.

[0010] In one alternative: the surface of the cooling pipe is provided with a limiting shell, and a thermally conductive patch is embedded inside the limiting shell. The water inlet pipe and the water outlet pipe of the cooling pipe are bonded together through the thermally conductive patch for heat transfer.

[0011] In one alternative: a water pump is provided on the surface of the cooling pipe, and the water pump is mounted on the surface of the cooling tank.

[0012] In one alternative: the venting frame is provided with a water baffle on the outside of the housing, the venting frame is provided with a filter screen inside the housing, and the venting frame is provided with several connecting sleeves on its side.

[0013] In one alternative: a button is slidably provided inside the connecting sleeve, and a guide groove is provided inside the button. The guide groove guides the movement of the guide block, and the guide block is fixedly connected to the surface of the transmission block.

[0014] In one alternative: a locking block is fixedly connected to the end of the transmission block, and a limiting seat is installed on the inner wall of the housing, with a slot on the limiting seat that matches the locking block.

[0015] In one alternative: the transmission block is connected to one end of the spring, and the other end of the spring is connected to the inner wall of the button.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a limiting shell to fix and limit the inlet and outlet water pipes of the cooling pipe, ensuring that the two pipes maintain a stable relative position. At the same time, the heat-conducting patch plays a heat-conducting role, efficiently transferring the heat of the heated cooling water in the outlet water pipe to the inlet water pipe, so that the low-temperature cooling water in the inlet water pipe and the high-temperature cooling water in the outlet water pipe can exchange heat. Ultimately, the overall cooling water temperature in the cooling pipe is close to uniform, effectively avoiding the problem of uneven heating or drastic temperature fluctuations in the battery due to excessive temperature difference between the inlet and outlet water pipes. This achieves uniform heat dissipation of the battery and ensures the safe operation of the battery.

[0017] 2. When the button of this utility model is pressed, the button slides along the inner wall of the connecting sleeve and drives the guide groove to move synchronously. The guide groove guides the guide block through its own groove structure and drives it to move accordingly. The spring continuously provides elastic force to press the guide block tightly against the inner wall of the guide groove, ensuring accurate guidance. When the guide block moves, it drives the transmission block, which in turn drives the locking block to rotate around the fixed point, realizing the action of the locking block locking into or disengaging from the locking slot. When the locking block is locked into the locking slot, the vent frame can be quickly fixed for easy installation. When it is disengaged from the locking slot, the vent frame can be easily disassembled for easy subsequent cleaning and maintenance. Attached Figure Description
