Z300T ZONCN Inverter picture

Overheating of high-voltage inverters is a common fault phenomenon that may cause equipment damage and shutdown. Therefore, it is very important to detect and solve overheating problems in a timely manner. The air (wind) water-cooled closed cooling system of high-voltage inverters is a cooling system that combines air cooling and water cooling technology, designed to effectively manage the heat of high-voltage inverters to ensure their reliable operation in high-power applications.

Basic principle of air (wind) water-cooled closed cooling system:

The air-water-cooled closed cooling system is a high-voltage inverter cooling equipment system that integrates high efficiency, environmental protection and energy saving. Its application technology is in a leading position in China. It has been widely promoted and applied in high-voltage and high-power inverter projects in the power, steel, cement, coal, chemical, petroleum, metallurgy and other industries. The high-voltage inverter cooling equipment system fundamentally solves the problems of high unit heat dissipation density and high equipment energy consumption. Thereby improving system safety and reliability and reducing operating costs.

The hot air of the inverter is directly exchanged through the air-water cooling device through the air duct, and the heat lost by the inverter is directly taken away by the cooling water. The cooled cold air is discharged back to the room. The cold water temperature in the air-water cooling device is lower than 33°C, which can ensure that the ambient temperature in the inverter room is controlled below 40°C after the hot air passes through the heat sink, meeting the inverter’s requirements for environmental operation, thereby ensuring a good operating environment in the inverter room.

Advantages of air (wind) water-cooled closed cooling system

Efficient cooling: Combining the advantages of air cooling and water cooling, it can effectively reduce the operating temperature of high-voltage inverters and improve system efficiency and reliability.

Strong environmental adaptability: Suitable for various industrial environments, including high temperature, high humidity, dust and other harsh conditions.

Closed system design: The coolant circulates in a closed system to avoid pollution and evaporation losses, and maintenance is simple.

Extend equipment life: An effective cooling system can reduce the thermal stress of components and increase the service life of the inverter.

Application scenarios of air (wind) water-cooled closed cooling system

High power application: Suitable for large industrial equipment and systems, such as steel mills, chemical plants, mines and other occasions that require high power drive.

High temperature environment: Suitable for occasions with high ambient temperature and poor natural cooling effect, such as tropical areas or industrial sites with dense equipment.

Systems requiring high reliability: Suitable for applications with high requirements for equipment reliability and stability, such as power systems, oil and gas and other key industries.

Through this air (wind) water-cooled closed cooling system, the high-voltage inverter can operate stably and efficiently under high load and harsh environment, effectively avoiding equipment failure and shutdown due to overheating.
