AI Technical Summary
Existing ventilation units have issues with rolling bearing cooling, such as requiring additional equipment for oil cooling and high requirements for water quality, quantity, and pressure for water cooling. In addition, some factory areas lack circulating water and have insufficient water supply, which affects the normal operation of the fans.
Design a self-cooled water-cooled ventilation unit, which uses an air-cooled cooler and a pipe heat exchanger. It uses the ambient temperature air during the operation of the fan for heat exchange and cooling. The circulating water circulates in a closed system and is cooled by the air-cooled cooler, without the need for an external water source.
It achieves a self-cooling effect without external water consumption, reducing equipment costs and floor space, and improving system reliability and energy efficiency.
