What Is A Mixed Heat Exchanger? Cooling Tower Is A Mixed Heat Exchanger
Jan 11, 2018

Mixed type heat exchangers rely on the direct contact of cold and hot fluids for heat transfer. This heat transfer avoids fouling resistance of the heat transfer walls and both sides, as long as the contact between the fluids is good, heat transfer rate is high. 

Where the fluids are allowed to mix with each other, mixed heat exchangers can be used, such as gas scrubbing and cooling, circulating water cooling, hybrid heating between steam and water, condensation of steam, and the like. Its applications span the chemical and metallurgical industries, power engineering, air-conditioning projects and many other manufacturing sectors. 


Cooling tower (or cold water tower) In this device, using natural ventilation or mechanical ventilation method, the production has been raised in temperature cooling water cooling and then recycled to improve the economic efficiency of the system. 

For example, the circulating water of a thermal power plant or a nuclear power plant, the cooling water in an ammonia production, and the like, are recycled after being cooled by a water cooling tower. This method has been widely used in practical projects.

Cooling tower is the use of air in contact with water (directly or indirectly) to cool the water equipment. Water is used as a circulating coolant, which absorbs heat from a system and discharges it to the atmosphere, lowering the temperature of the air in the tower to create a device that reuses the cooling water.


Cooling towers are mainly used in air conditioning cooling systems, refrigeration series, injection molding, leather, foam, power generation, steam turbine,Aluminum processing, air compressor, industrial water cooling and other fields, the most widely used for air conditioning cooling, freezing, plastic chemical industry. 

Specific division, as follows:


A, room temperature air conditioning categories: air conditioning equipment, cold storage, freezer, refrigeration, air conditioning and other heating and cooling; 


B, manufacturing and processing categories: food industry, medicine, metal casting, plastic industry, rubber industry, Chemical industry, petrochemical products, etc .; 


C, mechanical cooling category: generators, steam turbines, air compressors, hydraulic machines, engines, etc .; 


D, other types of industries


The role of the cooling tower is to carry cooling water in the tower Body heat exchange with the air, so that waste heat 

transfer to the air and dispersed into the atmosphere, the schematic diagram shown in Figure 1, the working principle shown in Figure 2, the physical map shown in Figure 3.
