Types of Hybrid Heat Exchanger

Hybrid heat exchanger is to rely on cold and hot heat transfer fluid for direct contact, this way to avoid heat transfer and heat transfer partitions on both sides of the fouling resistance, as long as the contact between the fluid in good condition, there is a large the heat transfer rate. Therefore, any occasion to allow the fluid mixed with each other, can be mixed heat exchanger, such as gas washing and cooling, cooling circulating water, steam - water mixture between the heating steam condensate, and so on. It can be applied throughout the chemical and metallurgical enterprises, power engineering, air-conditioning engineering, and many other manufacturing sectors.

According to different purposes, hybrid heat exchanger can be divided into several different types:

(1) heat exchanger cooling tower (or cooling tower) in this device, with natural ventilation or mechanical ventilation method, the production has increased the temperature of cooling water for cooling after the cycle in order to increase the economic efficiency of the system. Such as thermal power plants or nuclear power plants circulating water, ammonia production in the cooling water, cooling water cooling tower through recycling after use, this method in practical engineering has been widely used.
