How does the charging station dissipate heat
In recent years, the production and sales of new energy vehicles in China have increased rapidly, and the number of charging piles has gradually increased.
Compared with other power supplies, the system heat dissipation of the charging pile is much larger, and the requirements for the thermal design of the system are extremely strict. The power range of DC charging pile is 30kW, 60kW and 120kw, and the efficiency is generally about 95%. Then 5% of it will be converted into heat loss, and the heat loss will be 1.5KW, 3KW and 6kW. For outdoor equipment, these heat must be discharged from the equipment, otherwise the aging of the equipment will be accelerated. At the same time, waterproof and dustproof treatment shall be done to prevent electronic equipment failure.
At present, there are four commonly used cooling modes: natural cooling (mainly relying on heat sink), forced air cooling, liquid cooling and air conditioning. Due to the influence of volume, cost, reliability and other factors, at present, most companies use forced air cooling. Then, this is bound to bring dust, corrosive gas, moisture and other interference.
The heat dissipation of the charging pile is divided into module heat dissipation and the overall heat dissipation of the chassis. Because the charging module is built in, the protective measures are mainly reflected in the design of the charging pile chassis. The simplest and economical design is to make the louver type at the air inlet and outlet of the box, and then add a fan at the air outlet to remove the heat discharged by the module fan.
This method can play a certain protective role. After a long time, it is inevitable that dust and moisture will enter. If you want better protection effect, you can use closed cold and hot isolation air duct to isolate the inside: the middle partition plate completely separates the cold and hot fluids, and effectively cools down through the heat conduction carrier and the top fan. The louver filter screen group is selected for the air inlet and outlet at both ends to effectively prevent water and dust.
The charging pile heat dissipation system is a customized product. Sinda Thermal can provide the best scheme according to the working conditions such as power, air volume and heat dissipation. In addition, we can also customize various of radiators, air-coolingmodules, liquid cooling system,fan modules and other products.
