At the end of last year, the General Office of the State Council issued the "New Energy Vehicle Industry Development Plan (2021-2035)".By 2025, the sales volume of new energy vehicles will reach about 25%, and by 2035, domestic public sector vehicles will be fully electrified."New Infrastructure" focuses on technology-driven infrastructure construction and promotes the development of traditional industries to network, digital and intelligent.High-power charging, energy interconnection and orderly charging will be the development direction of "new infrastructure" charging piles.

Under the background of pressing the "fast forward key" in the construction of charging pile industry, the heat dissipation of equipment has become one of the problems that perplex the development of the industry.It is necessary for the vehicle to be charged to replenish more than 50-60% of the electric energy in a short time.At present, DC fast charging can be fully charged in 1-2h, and AC slow charging can be fully charged in 6-8h.Of course, the faster the trip, the better.However, if the charging speed is accelerated, the current and voltage will increase, resulting in rapid and massive heat generation.

Compared with traditional power supply, the system heat dissipation of charging pile is much larger, and the requirements for thermal design of the system are more stringent.Generally speaking, DC charging piles in public building charging stations have great charging power, long charging time and large heat generation.For outdoor equipment, this heat must be discharged from the equipment, otherwise it will accelerate the aging of the equipment, and even cause safety accidents in serious cases.At present, there are mainly natural cooling (mainly relying on fins), forced air cooling, water cooling and air conditioning modes applied to charging piles for heat dissipation.Due to the influence of volume, cost, reliability and other factors, most charging piles in the market are treated by forced air cooling.

For various application environments of charging piles, the cooling fans of Taiwan Province Sanju Motor have passed the practice test, and now they have reached cooperation with many manufacturers, and have been put into the market in large quantities.With excellent quality, high quality and long service life, whether it is in the damp and dark basement or outdoors exposed to the wind and the sun, the cooling fans of Sanju Motor can freely cope with various industrial control environments, timely ventilate and dissipate heat for charging piles, and greatly increase the service life of equipment.

The cooling fan of Miju Motor is made of high-quality aluminum, with various shapes of fan frames and blades, and oil-bearing and double ball bearing can be flexibly selected, with strong performance and strong wind power, which can greatly improve the cooling efficiency of charging piles, help to maintain a suitable working temperature and help to eliminate the hidden danger of thermal runaway; Compact structure, firm design, quiet operation, no need of external protective cover, which can reduce wind noise caused by wind shield and further enhance user experience.

Driven by the new infrastructure policy, the charging pile industry has entered a new stage of development.Sanju Motor will, as always, provide reliable cooling fan technology and high-quality service for users all over the world, so that charging piles can dissipate heat safely and efficiently.
