Description

A charging pile heat dissipation protection cabinet

[technical field]

The utility model relates to a protection cabinet, in particular to a cooling protection cabinet for a charging pile.

[Background technique]

With the increasing pollution of the whole country and the whole world, the strengthening of the awareness of environmental protection and the strengthening of the governance of the whole country and the world, as well as the development of battery technology and automobile technology, the popularity of new energy vehicles, especially electric vehicles, and the beginning of car charging piles universal. The current charging piles are divided into two categories: DC charging and AC charging, with power ranging from 60KW to 120KW, or even higher. The charging pile of each power is a process of energy conversion, from AC to DC and then to battery charging, there is an inevitable energy loss, and the energy loss is eventually converted into heat and lost to the atmosphere. The main lost electric energy is generated from the charging pile module. Taking the DC 120KW charging pile as an example, the general conversion efficiency is about 95%. According to this calculation, the dissipated heat is about 6.3KW;

At present, the actual products all adopt the direct ventilation scheme, that is, by preparing 6-8 sets of fans and forced air cooling, the heat generated by the charging pile module is blown out of the charging pile. The current solution mainly has three problems: 1. Fan heat dissipation. Since the inside of the charging pile cabinet is connected to the outside of the cabinet and is not an isolated space, the environmental problem of the charging pile module must be higher than the atmosphere. High, and high temperature is not conducive to the long-term work of the charging module, such as outdoor 45C, plus solar radiation, the heat of the module itself will exceed 55C or 60C, or even higher, will reduce the life of the charging module and reduce the output of the charging module , and even make the charging module enter its own protection state, resulting in no current output, the owner's fixed assets will be lost, and the user's experience will also be lost; 2. Since the inside of the charging pile cabinet is connected to the outside of the cabinet, the protection level is very low , will inevitably lead to water vapor, dust, dust, metal particles, etc. in the air entering the interior of the charging cabinet, resulting in pollution of the entire system, dirty and short-circuit problems, shortening the service life of the equipment, and even fire, explosion, leakage and other disasters happened.

[utility model content]

The solution to the technical problem of the utility model is to provide a heat dissipation protection cabinet for charging piles, including a cabinet body, a charging gun hook, a display monitoring screen, and an external lock. As a technical feature of the utility model: the cabinet body is provided with a cabinet The door and the cabinet wall, the outside of the cabinet door is provided with a hanging cooling device, the hanging cooling device is provided with a shell, and the shell is hollowed out; the inner wall of the cabinet is provided with a cooling device, and the cabinet door and the cabinet A sealing device is provided between the walls and between the cabinet walls, and a temperature regulating device is provided at the bottom of the cabinet.

Preferably, the temperature adjusting device is a heating device.

Preferably, the charging gun hook and the display monitoring screen are all arranged outside the cabinet wall, and cabinet feet are provided at the bottom of the cabinet body, and the cabinet feet are fixed to the ground by bolts.

Preferably, the cooling device is a cooling device or a cooling device.

Preferably, a partition is provided inside the cabinet, and the partition is located in the gap between the charging device and the cabinet door.

Preferably, the partition is perpendicular to the cabinet door, and the partition is flexibly connected to the cabinet door.

Preferably, the inside of the cabinet is provided with a charging pile card position, and the charging pile is located at the charging pile card position.

Compared with the prior art, the utility model is a heat dissipation protection cabinet for charging piles, which wraps the charging piles inside the cabinet as a whole, isolates water vapor, dust, fine dust, metal particles, etc. in the air, and prolongs the service life of the charging piles. , At the same time, a cooling and cooling device and a temperature regulating device are installed inside the cabinet to ensure the normal working temperature of the charging pile.
