Heat Exchangers are a device which is designed to efficiently exchange or transfer heat from one matter to another.
Heat is transferred by conduction through the exchanger materials, which separate the two mediums being used. When a fluid is used in heat transfer, it could either be oil, water, or air.
Also, they are designed to remove excess heat from engines of aircraft, lasers, x-rays, military equipment and many other types of equipment, which require cooling beyond what air can provide.
There are various types of heat exchangers. When considering the use of a heat exchanger, it is important to be sure of the medium going to be used:
Water is predominantly used for plant cooling purposes, in heat exchangers and condensers.
The presence of debris or salts has a negative impact on plant performance and can result in high operating and maintenance costs. Hence, choosing the right type of heat exchanger to a particular type of industry is vital.
