Closed cooling tower for intermediate frequency furnace

Introduction

　　The Closed cooling tower is a type of closed cooler used in the manufacturing industry. Equipment that requires water for cooling is very common. Traditional water cooling methods consume a lot of water and have high maintenance costs for operation and use of equipment. The working fluid of the cooling tower is in a closed cycle, using high-efficiency heat exchange circular tubes as heat conductors, and heat is exchanged through air. The significant features of using a closed cooling tower are stable circulating water quality, high heat transfer efficiency, and low operating costs.

• Strong corrosion resistance and rich experience
• Quality Installation Quality Assurance
• Stable operation and after-sales service
• The strength of manufacturers continues to improve

Working principle

◆Mainly relying on the rapid evaporation of the water film on the outer surface of the pipe to enhance the heat transfer outside the pipe, thereby achieving the purpose of cooling the soft water inside the pipe. This is mainly because water has a high latent heat of vaporization (the latent heat of vaporization of water at one atmosphere is 570 kal/kg), which greatly improves the overall heat transfer efficiency. When the equipment is running, the evaporation of the water film on the outer surface of the tube causes the humidity of the air to greatly increase and approach saturation after passing through the tube bundle. The axial flow fan extracts the humid air and passes it through the mist eliminator located above the water spray system, removing the water droplets carried in the humid air and discharging it into the atmosphere through the air inlet. Because the axial flow fan is located at the upper part of the equipment, a negative pressure area is formed at the lower part of the axial flow fan when air is drawn upwards, which accelerates the evaporation of the water film on the outer surface of the pipe and enhances the heat transfer outside the pipe.
