One, in accordance with the principle of classification:

Direct contact heat exchanger

This type of heat exchanger 's main principle is the two medium upon contact with each other to achieve heat transfer, heat transfer, contact area directly affects the heat transfer, the heat exchanger medium which is a gas, a liquid, is the main tower equipment as the main body of the heat transfer equipment, but also relates to mass transfer it is difficult to distinguish between, with the tower 's relationship, usually centralized for tower equipment, power plant cooling tower is the most typical of the direct contact heat exchanger.

Energy storage type heat exchanger (the accumulator), this kind of heat exchanger with little dosage, principle of heat medium by heating the solid material to reach a certain temperature, cooling medium through the solid material is heated, so that the purpose of reaching heat transfer.

Dividing wall type heat exchanger

This type of heat exchanger the amount is very large, occupy the 99% above of gross, principle of heat medium through a metal or non metal heat is transferred to a cooling medium, such heat exchangers are usually referred to as the shell and tube type, plate, plate fin type or plate type heat exchanger.

In two, according to the classification of heat transfer

In 1, no phase change heat transfer

Generally divided into the heater and cooler.

In 2, a phase change heat transfer

Generally divided into condenser and reboiler. Reboiler is divided into a kettle reboiler, siphon reboiler, reboiler, an evaporator, a steam generator, a waste heat boiler.
