AI Technical Summary
The top fans of existing closed-circuit cooling towers are exposed to high temperature and humidity environments for extended periods, leading to increased failure rates and high maintenance costs.
The fan is positioned on the lower side of the casing and uses a blower design. Inside the casing, there are guide vanes and baffles to improve airflow and prevent the fan motor from being in a high-temperature and high-humidity environment for a long time. Two fans are also installed to be used in rotation to increase ventilation.
It reduced the failure rate of the fans, extended their service life, reduced maintenance costs, and improved cooling efficiency and production reliability.
