Importance of heat dissipation of EV Charging Cooling Pump

Published:2022-11-18

Whether new energy vehicles can be popularized rapidly depends on whether the relevant supporting facilities of infrastructure construction are perfect. Compared with electric equipment, laser equipment, LED heat dissipation and other industries, the charging pile must have higher current to meet the characteristics of faster charging, and the heat dissipation requirements are more stringent. Therefore, this time mainly discusses the importance of the charging pile water pump for the heat dissipation of the charging pile.


Why does the Charge Point generate a lot of heat?


The purpose of the charging pile is to enable the vehicle to be charged to supplement more than 50% of the electric energy in a short time. The ideal state is to supplement more than 80% of the electric energy in one minute. At this time, it will face a very serious problem. The charging pile will generate a lot of heat due to rapid charging, which will cause the internal temperature of the charging pile to be too high. From the perspective of the concept of thermal transmission, if the heating capacity of the heating element itself is average during the cooling process of the charging pile, it means that the inductance module The more heat the power module and other components generate, the greater the safety accident will be caused if the excess heat is not removed in time. Therefore, heat dissipation is one of the problems that the charging pile must solve!

Why choose liquid cooling charging post?


So how should we heat the charging pile? The traditional scheme is a cooling fan. The disadvantage of this technology is that after a long time of use, outdoor dust can easily enter the charging pile, which not only affects the heat dissipation of the charging pile, but also pollutes other precision electronic components. Today, hundreds of kilowatts of charging power are available. The traditional air cooling can no longer meet the cooling needs of high-power charging piles. The features of liquid cooling charging technology, such as silence, efficiency, temperature, green and safety, will perfectly help the development of electric vehicle industry.


Importance of water pump for liquid cooling charging pile


The principle of the liquid cooling technology used by the charging pile is not complicated. To put it simply, a special circulation channel is set between the cable and the charging gun. The channel is filled with coolant for heat dissipation. The liquid circulation is driven by the Shenpeng water pump to bring out the heat. The core of the liquid cooling heat dissipation of the charging pile is the circulation of the water pump. Therefore, an excellent water pump can not only improve the heat dissipation performance of the charging pile, but also have the advantages of long service life, maintenance free, etc., so as to improve the charging performance of the electric vehicle.


How should we choose a charging pile pump?


1. The quality and performance of the charging pile water pump selected from the vehicle specification level are better. The Shenpeng charging pile water pump has passed the strict system certification of ISO9001, IATF16949, ISO14001, OHSAS18001 in the industry, and its quality and quality are more guaranteed.


2. The water pump manufacturers cooperating with large vehicle enterprises will be selected to control the production of charging pile water pumps more strictly. Shenpeng officially entered the automotive field in 2011. At present, it has developed more than 30 products of 20-30W, 40-130W and 200-300W series, and has successively cooperated with large domestic automobile enterprises such as Dongfeng, FAW, Shaanxi Automobile, BAIC, Zhengzhou Nissan, Geely, Chery, Ejett, BAIC, BYD, Chang'an Automobile, Great Wall Automobile, Jiangling Automobile, SAIC GM Wuling, LEAD, Hezhong, etc.


3. Select a variety of certified water pump manufacturers, and the external support will be more reassuring. The products produced by Shenpeng have passed CE, ROHS, REACH and TSCA certification, and some products have obtained UL and FDA food grade certification.


As a company that developed DC brushless water pump earlier in China, Shenzhen Pengzhou has 18 years of industry production and research experience, CNAS standard laboratory, 300,000 level dust-free workshop, 10 professional production lines of electronic water pump, etc. Shenzhen Pengzhou charging pile water pump guarantees the heat dissipation of your charging pile.
