What Is a Closed Cooling Tower for Aluminum Melting Furnace?
With an aluminum melting furnace, we can frequently find a closed cooling tower. Apparently, we know what the closed cooling tower is used for. We just know it, but don’t know why and how it works. In this article, we will tell you there.
A closed cooling tower is a type of cooling equipment. Its working principle is to ensure the cooling effect by utilizing the heat exchange between circulating air, spray water and circulating water. This type of cooling tower places a tubular heat exchanger inside the tower to achieve a cooling effect through heat exchange with air and spray water. Because it is a closed cycle, it can ensure that the water quality is not polluted, well protect the efficient operation of the main equipment, and improve the service life.

Closed cooling towers have important applications in induction melting furnaces. Induction melting furnace is a device that uses the principle of electromagnetic induction to heat metal materials. It is widely used in metallurgy, casting, machinery manufacturing and other fields. During the operation of the induction melting furnace, a large amount of heat will be generated, and a cooling system is required to reduce the temperature of the furnace body to ensure the normal operation of the equipment.
How does a closed cooling tower work?
The theoretical basis of the closed cooling tower is the second law of thermodynamics, that is, heat will flow from high-temperature objects to low-temperature objects. It works by spraying hot water onto the radiator while placing the radiator in air below the water level in the tank, creating a process in which water droplets fall. During the descent process, the water droplets exchange heat with the air and absorb the heat in the air, thereby cooling the water.
The main components of a closed cooling tower include a water tank, air collector, blower, tower body and water pump. Its working principle is to adjust the heat transfer between cooling water and air to achieve the cooling effect. The cooling water is transported from the water tank to the tower body through the water pump, flows down the tower body surface, and meets the dry air blown by the upper blower, resulting in heat transfer and material transfer between the water and the air. At this point, the heat in the water is transferred to the air, forming a stream of water vapor as the water evaporates. The blower beats the water vapor into the gas collector, and then introduces it to other links for processing. Through this transfer method, the temperature of the water continues to drop, and finally returns to the water tank for recirculation.
In the above process, the function of the blower is to provide dry air to the tower body, maintain the flow rate and direction of the air, and ensure smooth heat transfer between water and air. The function of the water pump is to adjust the flow of cooling water, thereby adjusting the residence time of water in the tower. The function of the gas collector is to collect the water vapor beaten from the blower and introduce it to other equipment for processing.
