Understanding Concept and Application of Heat Exchangers

In this article let’s try to understand that, what is the heat exchanger and why to consider it, the former definition of that says it is a device that channelizes the heat from one medium to other medium, either by direct contact or by means of the induction.
Virtually all major industrial processes such as heating, refrigeration, air conditioning, power plants, chemical processing plant , plastic, rubber, pharmaceutical, petroleum refineries, natural gas processing, and sewage treatment finds the application of the heat exchanger some or the other way. The efficiency and the rate of the transfer of the thermal energy of heat exchanger plays very critical role in the performance of the heating, drying and cooling.
The heat exchangers are generally of three basic classifications based on the heat flow

  • Parallel flow: where the fluids runs in same direction, parallel to each other.
  • Counter flow: where the fluid runs in opposite direction. 
  • Cross flow: where the fluids travel perpendicular to each other. 

Heat exchangers are also classified based on the construction:

  • Shell and tube heat exchanger
  • Plate heat exchanger
  • Plate and shell heat exchanger
  • Fluid heat exchangers
  • Plate fin heat exchanger 
  • Regenerative Heat Exchanger

Transfer of the heat for the diverse applications such as water to water, air to water, water to air, and air to air.
Heat exchanger avoids the direct contact hence high temperatures can not cause overheating but they could potentially start a fire in a unit if the temperature remains too hot for a period of time. Heat exchanges are used in a diverseness of industries such as home appliances, heating and cooling, marine and boating, ventilation and air flow, industrial manufacturing and many more. So many of the items that we use every day contain a heat exchanger in them and we never really think about the role that they play in these pieces.
You can ask the experts such as KERONE those are pioneer in manufacturing and designing of heat exchanger they will tell you how much this is important and what it exactly does when designed properly and consequences if not properly designed and taken care. We can be reached at info@kerone.com .
