AI Technical Summary
Existing cooling towers are prone to freezing and cracking in cold climates, leading to leaks in the core heat exchange coils, affecting production safety and preventing efficient indoor operation.
The heat exchanger module is placed indoors and protected by a steel casing. The air intake mechanism is automatically opened and closed by the gravity change of the water tray. Combined with the hydraulic drive wheel and cleaning brush, it achieves antifreeze and cleaning, avoids freezing and cracking and improves efficiency.
It effectively prevents heat exchange coils from freezing and cracking, ensures uninterrupted operation throughout the year, improves equipment safety and lifespan, and maintains high-efficiency heat exchange performance.
