Heat Exchanger – An Effective Equipment Used In All Aspects Of Applications

Heat exchanger is an industrial equipment specially designed heat exchanger fabrication and built for heat transfer from one medium to another, commonly used in industries and factories for transferring the energy of heat. This equipment is separated by a solid wall which prevents mixing up of medium with each other. At one side of the wall, it is associated with hot fluid, and at the other side it has the cool fluid which flows through the channels. It is designed for the purpose of heat transfer and it can conveniently and efficiently perform this function for the industry needs. In order to make heat transfer possible, fins and corrugations are frequently included in it’s design.

This piece of equipment is widely used in almost all industry applications namely refrigeration, power plants, space heating, chemical plants, petroleum refineries, natural gas processing, air conditioning, sewage treatment, natural gas processing, and many more. Heat exchanger is mostly found in an internal combustion engine.

There are different types of heat exchanger and these include shell and tube, plate, adiabatic wheel, plate fin, pillow plate, dynamic scraped surface and many more. The shell and tube or flat plate devices are commonly used. The shell and tube exchanger associated with numerous tubes that are often collectively known as a bundle. This bundle has a shell inside or a pressure vessel. This is used for the purpose to heat or cool the fluid. It is usually adopted in industries having high pressure applications. A flat plate heat exchanger consists of several sheets of stainless steel which is assembled in a stack. The shell and tube as well as flat plate heat exchanger offer higher heat transfer coefficients. The structure of the device is uniquely designed to allow more surface area and increase efficiency of the heat transfer device. This is also five times lighter than the shell and tube device.

For industry applications, Gasketed plates are often preferred as it can be conveniently disassembled for tune-ups and cleaning. The exchangers are classified as per the flow arrangement including parallel flow, counter flow and cross flow. This is commonly made from durable materials namely iron, steel copper and aluminum. To transfer heat effectively, the device must be equipped with corrosion resistant parts.
