Problems solved by technology

In addition, the existing water-medium heat dissipation and cooling system or air-medium heat dissipation and cooling system have complex pipelines and many sealed joints, which are prone to leakage accidents. These two heat dissipation methods have gradually failed to meet the requirements
[0004] Wind media cooling is used to cool down. Due to the high heat inside the charging pile, multiple fans are required to dissipate heat at the same time, which has the disadvantages of poor cooling effect and high noise.
[0005] Chinese patent application number: 201610178423.1 discloses an internal partition structure of a mobile charging pile, including a control area, a high-voltage area, an air intake and wind direction guidance area, and a battery system area. The high-voltage area mainly includes 22V inverters, transformers, and 24V DC Converter, high-voltage DC copper bar, charger; the air intake and wind direction guide area includes the first set of louvers with dust-proof nets, the second set of louvers and cooling fans; the cooling fans are fixed on the first set of louvers, used In order to draw the hot air inside the mobile charging pile to the surrounding environment, the second set of louvers is fixed on the other side of the mobile charging pile housing to allow the outside air to flow in. In this patent, the cooling device is a fan, which dissipates heat poor effect
[0006] In addition, the above invention uses wind media to cool down the temperature to dissipate heat, and the heat dissipation effect is not good.

Embodiment 1

[0048] combined with Figure 1-4 , describe the present invention in detail.

[0049]A heat dissipation device, comprising a cooling chamber, the lower end of the cooling chamber has an outer cylinder support wall 13 and an inner cylinder support wall 14, the outer cylinder support wall 13 extends upwards to form a cylindrical first roundabout wall 4; the inner cylinder supports The wall 14 extends upwards to form the second roundabout wall 5 . The first roundabout wall 4 crosses the second roundabout wall 5 and bends inwardly to form an arc-shaped transition support wall 17. There is a gap between the transition support wall 17 and the second roundabout wall 5, and the transition support wall 17 is parallel to the second roundabout wall. 5 continues to extend to form a third roundabout wall 6 . So far, the cavity wall of the cooling chamber presents a three-return detour wall structure, which are respectively the first detour wall 4 , the second detour wall 5 and the third ...

Abstract

Provided in the invention is a charging pile system with an own heat dissipation device. The charging pile system is composed of a main charging circuit and a central processor. The main charging circuit is connected with the central processor. The main charging circuit consists of a rectifier module and a power conversion module. The central processor includes a communication unit and a control unit. The communication unit is responsible for network connection between the central processor and an external system; the control unit is responsible for receiving an instruction from the central processor and controlling e components connected with the central processor. Besides, a charging pile further includes a heat dissipation device, a three-way valve, a water pump and an oil pump; and thethree-way valve is connected with the oil pump, the central processor and the heat dissipation device. With flowing of water in a cooling pipe, the heat dissipation effect of coolant oil in the heatdissipation device is improved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging, and in particular relates to a charging pile system with a heat dissipation device. Background technique [0002] Recently, with the rapid development of electric vehicles, the development of charging piles for electric vehicles has emerged as the times require. During the charging process of charging piles for electric vehicles, the transformers, rectifier modules and circuit boards of the charging piles will generate heat, and as the heat continues to dissipate, The temperature inside the entire charging pile will rise rapidly. When the heat inside the charging pile reaches a certain temperature value, the high temperature environment will affect the stable operation of the transformer, rectifier module and circuit board inside the charging pile, and electronic failure may occur to reduce the charging pile. charging efficiency. If multiple problems inside the charging pile oc...
