Description

Technical Field

[0001] This utility model relates to cooling tower technology, and more particularly to a cooling tower motor replacement component. Background Technology

[0002] Currently, cooling towers, as the core heat dissipation equipment in industrial circulating water systems, typically have top fan motors with power ranging from tens to hundreds of kilowatts, which are key driving units for maintaining air-water heat exchange. Due to long-term exposure to high temperature and humidity environments, the motors require regular maintenance or replacement.

[0003] Patent document with application number "CN201610831210.4" discloses a cooling tower. The tower body has an air inlet on its side, a ventilation device at the top, and an atomizing device in its middle. The tower body also has an inlet pipe and an outlet pipe. A rotating shaft runs vertically through the middle of the ventilation device, and a rotating sleeve is rotatably fitted onto the shaft. Guide vanes are evenly distributed circumferentially on the outer surface of the ventilation device, and the ventilation device also has guide grooves. A central shaft runs vertically through the middle of the atomizing device, and a vortex sleeve is rotatably fitted onto the central shaft. Fan blades and atomizing nozzles are evenly distributed circumferentially within the atomizing device. The water spray direction of the atomizing nozzles is parallel to the tangent direction of the outer circumferential surface of the vortex sleeve, and the water spray direction of each atomizing nozzle is consistent along the circumference of the vortex sleeve. A rotating water chamber connected to the inlet pipe is also provided within the atomizing device. This cooling tower has low energy consumption and high cooling efficiency.
