Characteristics of liquid-cooled cables for different media

China [CN]

According to the understanding that the market's requirements for the charging capacity of electric vehicles are constantly increasing, high-power fast charging has now become one of the options for the development of electric vehicle companies, which also means that the utilization rate of liquid-cooled high-power charging cables will be greatly increased. We can now also see more and more liquid cooling cables on the market appearing in major charging stations. Liquid-cooled cables are divided into two different types: oil-cooled and water-cooled.

Among them, the biggest difference is the difference in cooling medium. Oil cooling refers to the use of heat transfer medium oil to dissipate heat. Water cooling uses water as the heat transfer medium to dissipate heat. Oil cooling and water cooling are two commonly used structural cables for liquid cooling cables. They have different applications and characteristics. Which one you choose depends on actual needs. So what is the difference between liquid-cooled cables and oil-cooled and water-cooled cable structures?

Depending on the cooling medium, the corresponding liquid cooling cable structures are also quite different. The liquid cooling cable structure of water + refrigerant medium is to place a separate liquid cooling pipe next to the DC+/DC- conductor (the cooling pipe is outside the conductor) to take away the heat of the conductor. The liquid-cooled cable structure of insulating oil medium places the conductor in the coolant to dissipate heat, and the coolant wraps the bare conductor.
