[0002] A cooling tower is a device that uses water as a circulating coolant, absorbs heat from the system and discharges it into the atmosphere to lower the water temperature. Its cooling is achieved by utilizing the heat exchange between water and air flow to generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer, and radiation heat transfer to dissipate the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature. This is an evaporative heat dissipation device to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower. When building a cooling tower, a cooling fan needs to be installed. The fan is usually installed at the top of the cooling tower to supply air to the tower to help exchange heat between the filler and the cooling water, thereby achieving cooling of the cooling water. When using a cooling tower fan, its own operation will generate noise and vibration, resulting in poor use of the cooling tower fan, and a shock-absorbing and noise-reducing device is required for shock-absorbing and noise-reducing.
