Description

Technical Field

[0001] The present application relates to the technical field of air circulation heat dissipation of charging piles, and in particular to an air circulation heat dissipation component of a charging pile. Background Art

[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels.

[0003] However, in actual applications, most of the existing charging piles are equipped with exhaust fans inside to discharge hot air by increasing air flow for the purpose of heat dissipation. However, this heat dissipation method is easily restricted by the ambient temperature, especially in the hot summer in the south. The natural environment is already high in temperature under the scorching sun, which will lead to a decrease in the heat dissipation effect of the charging pile. Over time, the components inside the charging pile will age due to being in a high temperature state for a long time, resulting in a reduction in service life.

[0004] Therefore, those skilled in the art provide a charging pile air circulation heat dissipation component to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to solve the problem raised in the above background technology that in the hot summer in the southern region, the natural environment is already at a high temperature under the scorching sun, which will lead to a reduction in the heat dissipation effect of the charging pile. Over time, the components inside the charging pile will age due to being in a high temperature state for a long time, resulting in a reduction in the service life, the present application provides a charging pile air circulation heat dissipation component.

[0006] A charging pile air circulation heat dissipation component provided in the present application adopts the following technical solution: it includes a charging pile body, a processing box is fixedly connected to the right side of the charging pile body, a heat dissipation pipe is fixedly connected to the right side of the charging pile body, an air pump is fixedly connected to the bottom side of the processing box, a heat exchange pipe is fixedly connected to the right side wall of the processing box, a rotating rod is rotatably connected to the center of the inner wall of the heat exchange pipe, three partitions are fixedly connected to the outside of the rotating rod, an air outlet pipe of the air pump is fixedly connected to the heat exchange pipe, a plurality of connecting pipes are fixedly connected to the top side of the heat exchange pipe, the processing box is fixedly connected to the right side of the charging pile body with the same L-shaped elbow, and the interior of the heat exchange pipe is filled with coolant.

[0007] Preferably, the angles between the three partitions are all one hundred and twenty degrees, and the outer end surfaces of the three partitions are all arc-shaped.

[0008] Preferably, the heat exchange tube is made of copper metal, and a semiconductor refrigeration plate body is installed on the right side of the heat exchange tube.

[0009] Preferably, a one-way valve is fixedly installed on the inner wall of the air outlet pipe of the air pump.

[0010] Preferably, a dustproof net is sleeved on the outer side of the air inlet pipe of the air pump.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] 1. By setting up heat exchange tubes and coolant, the air pump pumps the outside air into the heat exchange tubes. At this time, the air will exchange heat with the coolant, so that the air can be cooled down. The cold air enters the interior of the charging pile body through the L-shaped elbow, so that the interior of the charging pile body can be cooled down. The hot air inside the charging pile body is continuously injected with cold air and discharged from the heat dissipation pipe, thereby achieving the purpose of heat dissipation of the charging pile body. Compared with the traditional fan heat dissipation method, it can avoid the problem of poor heat dissipation effect due to ambient temperature limitation, thereby increasing the service life of components and reducing the aging rate.

[0013] 2. By setting the angles between the three partitions to be 120 degrees, the outer end faces of the three partitions are all designed to be arc-shaped. When external air enters the heat dissipation pipe, the bubbles will temporarily stay at the position of the angle between the two partitions to exchange heat with the coolant. When the injected air increases and the buoyancy increases, the partition is overturned by the buoyancy of the bubbles, so that the cooled bubbles can be discharged from the connecting pipe. The use of partitions can effectively increase the heat exchange time between air and coolant, thereby improving the heat exchange and cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present application embodiment discloses a charging pile air circulation heat dissipation component, referring to Figure 1-3, including a charging pile body 1, a processing box 2 is fixedly connected to the right side of the charging pile body 1, a heat dissipation pipe 3 is fixedly connected to the right side of the charging pile body 1, an air pump 4 is fixedly connected to the bottom side of the processing box 2, a heat exchange tube 5 is fixedly connected to the right side wall of the processing box 2, a rotating rod 6 is rotatably connected to the center of the inner wall of the heat exchange tube 5, three partitions 7 are fixedly connected to the outer side of the rotating rod 6, an air outlet pipe of the air pump 4 is fixedly connected to the heat exchange tube 5, a plurality of connecting pipes are fixedly connected to the top side of the heat exchange tube 5, the processing box 2 and the right side of the charging pile body 1 are fixedly connected to the same L-shaped elbow 8, and the interior of the heat exchange tube 5 is filled with coolant; by setting the heat exchange Tube 5 and coolant, the air pump 4 pumps the outside air into the heat exchange tube 5, at this time the air will form heat exchange with the coolant, so that the air can be cooled, and the cold air enters the interior of the charging pile body 1 through the L-shaped elbow 8, so that the interior of the charging pile body 1 can be cooled, and the hot air inside the charging pile body 1 is continuously injected with cold air and discharged from the heat dissipation pipe 3, so as to achieve the purpose of heat dissipation of the charging pile body 1. Compared with the traditional fan heat dissipation method, it can avoid the problem of poor heat dissipation effect due to ambient temperature limitation, thereby increasing the service life of components and reducing the aging rate.

[0021] In the present application, the angles between the three partitions 7 are all one hundred and twenty degrees, and the outer end surfaces of the three partitions 7 are all designed in an arc shape; by setting the angles between the three partitions 7 to be one hundred and twenty degrees, and the outer end surfaces of the three partitions 7 to be designed in an arc shape, when external air enters the heat dissipation tube 3, the bubbles will temporarily stay at the position of the angle between the two partitions 7 to exchange heat with the coolant. When the injected air increases and the buoyancy increases, the partition 7 is affected by the buoyancy of the bubbles and flips over, so that the cooled bubbles can be discharged from the connecting tube. The partition 7 can effectively increase the heat exchange time between the air and the coolant, thereby improving the heat exchange and cooling effect.

[0022] In the present application, the heat exchange tube 5 is made of copper metal, and a semiconductor refrigeration plate body 9 is installed on the right side of the heat exchange tube 5; by setting the heat exchange tube 5 to be made of copper metal, the semiconductor refrigeration plate body 9 can cool the coolant through the heat exchange tube 5 to avoid the temperature of the coolant from rising due to long-term use. At the same time, the heat exchange tube 5 made of the high heat transfer rate of copper metal can increase the cooling speed of the coolant.

[0023] In the present application, a one-way valve is fixedly installed on the inner wall of the air outlet pipe of the air pump 4; by setting the one-way valve, the one-way valve can be used to prevent the coolant from flowing back from the air outlet pipe of the air pump 4 into the air pump 4.

[0024] In the present application, a dust-proof net is sleeved on the outer side of the air inlet pipe of the air pump 4; by setting the dust-proof net, when the air pump 4 pumps outside air into the heat exchange tube 5, the dust-proof net can filter the dust in the air to prevent dust from entering the coolant.

[0025] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

[0026] The implementation principle of an air circulation heat dissipation component of a charging pile in an embodiment of the present application is as follows: when in use, the air pump 4 pumps external air into the interior of the heat exchange tube 5. At this time, the air will form heat exchange with the coolant, so that the air can be cooled down. The cold air enters the interior of the charging pile body 1 through the L-shaped elbow 8, so that the interior of the charging pile body 1 can be cooled down. The hot air inside the charging pile body 1 is continuously injected with cold air and will be discharged from the heat dissipation tube 3, so as to achieve the purpose of heat dissipation of the charging pile body 1. Compared with the traditional fan heat dissipation method, the problem of poor heat dissipation effect due to ambient temperature limitation can be avoided, the service life of components is increased and the aging speed is reduced. When the external air enters the heat dissipation tube 3, the bubbles will temporarily stay between the two partitions. 7 is used for heat exchange with the coolant. When the injected air increases and the buoyancy increases, the partition 7 is overturned by the buoyancy of the bubbles, so that the cooled bubbles can be discharged from the connecting pipe. The partition 7 can effectively increase the heat exchange time between the air and the coolant, thereby improving the heat exchange and cooling effect. The semiconductor refrigeration plate body 9 can cool the coolant through the heat exchange tube 5 to avoid the temperature of the coolant from rising after long-term use. At the same time, the heat exchange tube 5 made of copper metal with high heat exchange rate can increase the cooling speed of the coolant. The one-way valve can prevent the coolant from flowing back from the outlet pipe of the air pump 4 to the air pump 4. When the air pump 4 pumps the outside air into the heat exchange tube 5, the dustproof net can filter the dust in the air to prevent the dust from entering the coolant.
