Lord Fin Tube--Types of heat exchangers

A heat exchanger is a device that transfers heat from one fluid to another. Because of their various applications, heat exchangers have many different types.

Heat exchanger is an energy-saving equipment that can transfer heat between materials between two or more fluids at different temperatures. It is used to transfer heat from the fluid with higher temperature to the fluid with lower temperature, so that the fluid temperature can meet the requirements of process conditions, and it is also one of the main equipment to improve energy utilization.

Heat exchanger is a device that transfers part of the heat flow to cold fluid. Heat exchanger plays an important role in the production of chemical, petroleum, electric power, food and other industries, playing the role of heating, cooling, condensation, evaporator and reboiler in chemical production.

There are several types of heat exchangers:

1、 Interwall heat exchanger

The intermediate wall heat exchanger is composed of casing heat exchanger, immersed coil heat exchanger, spray heat exchanger, shell and tube heat exchanger, plate heat exchanger, etc.

The shell and tube heat exchanger is mainly composed of shell, tube bundle, tube sheet, head and other parts. The shell is mostly circular, with parallel tube bundles or spiral tubes installed inside. Both ends of the tube bundle are fixed on the tube sheet. There are two kinds of fluids for heat exchange in the tube shell heat exchanger, one is flowing in the tube, and its stroke is called the tube side; The other type flows outside the tube, and its stroke is called shell pass.

Plate heat exchanger is the most typical inter wall heat exchanger, and its main structure includes two parts: heat exchange plate and rubber strip between plates. Plate heat exchanger has replaced shell and tube heat exchanger in many industries due to its unique advantages.

2、 Regenerative heat exchanger

Regenerative heat exchanger is a heat storage body composed of solid materials, which transfers heat from high temperature fluid to low temperature fluid. The thermal medium heats the solid materials first, and then the cooling medium heats the solid materials after reaching a certain temperature to transfer heat. Regenerative heat exchanger includes rotary type, valve switch, etc.

3、 Mixed heat exchanger

The heat transfer of the mixed heat exchanger depends on the direct contact of cold and hot fluids. This heat transfer mode avoids the generation of fouling resistance on the heat transfer wall and both sides, and has a high heat transfer rate.
