Application of cooling fan in charging pile industry

    Why the charging pile needs to use a cooling fan, because the internal of the charging pile will produce a certain amount of heat, if the heat is not discharged, it will affect the efficiency of the charging pile. So when choosing fans, we should use some of the ones with large exhaust air volume, fast exhaust speed and good stability. The most important thing is waterproof and dust-proof. Because most charging piles are outdoors, they are exposed to the sun and the wind and rain, which need our consideration. Haoray fan 803812038 large air volume wind pressure series axial flow fan is designed and manufactured for the customer demand of charging pile industry, which can meet your needs!

    Horay fan is usually installed in the cabinet of electrical equipment, and sometimes it is integrated on the motor. Because of its compact structure, it can save a lot of space and is easy to install, so it is widely used.

    The charging pile is similar to the filling machine in the gas station, and can be charged for various electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with the AC power grid, and the output end is equipped with charging plug to charge electric vehicles. Charging piles generally provide two charging modes: conventional charging and quick charging. People can use specific charging cards to swipe cards on the man-machine interaction operation interface provided by charging piles, and print charging methods, charging time and expense data. The display screen of charging pile can display data such as charging amount, cost and charging time.

    Compared with other power sources, the system heat dissipation of charging pile is much larger, and the requirements for system thermal design are very strict. The power range of DC charging pile is 30kW, 60kW and 120kw, and the efficiency is generally about 95%. Then 5% of them 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 equipment will be accelerated, and the treatment of waterproof and dust-proof shall be done to prevent short circuit and signal disorder of electronic equipment.

    There are four kinds of refrigeration modes: natural cooling (mainly relying on heat sink), forced air cooling by hooray fan, water cooling and air conditioning. Due to the influence of volume, cost and reliability, most companies are using the method of hoopay fan forced air cooling. So, this will bring about dust, corrosive gas, moisture and other interference. The cooling of charging pile is divided into module heat dissipation and overall heat dissipation of the chassis. Because the charging module is built in it, the protective measures are mainly reflected in the design of the chassis. The simplest and economical design is to make the louver type at the inlet and outlet of the box, and then add the hooray fan to the air outlet to pump the heat from the module fan.

    The hooray fan hd8038 and hd12038 fan series have high efficiency and high protection design, which can provide the protection of dust-proof and water-proof IP65 and gr487 salt fog resistance, and meet the best heat dissipation scheme of solar PV inverter, ESS energy storage system, charging pile and other energy equipment operating in harsh environment.
