Heat Exchangers Basics Design Applications

A heat exchanger is a device designed to efficiently transfer or exchange heat from one matter to another. When a fluid is used to transfer heat, the fluid could be a liquid, such as water or oil, or could be moving air. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The most well-known type of heat exchanger is a car radiator. In a radiator, a solution of water and ethylene glycol, also known as antifreeze, transfers heat from the engine to the radiator and then from the radiator to the ambient air flowing through it. This process helps to keep a car's engine from overheating. For efficiency, heat exchangers are designed to maximise the surface area of the wall between the two fluids, while minimising resistance to fluid flow through the exchanger. The exchanger's performance can also be affected by the addition of fins or corrugations in one or both directions, which increase surface area and may channel fluid flow or induce turbulence. Heat Exchangers - Basics Design Applications offers comprehensive information on particular cases of heat exchangers. Beside the questions of thermodynamic basics, the book discourses numerous important issues, such as conceptions, design, operations, fouling and cleaning of heat exchangers. The book is not inevitably anticipated to be an elementary source of the knowledge in the area it covers, but moderately a guide while pursuing detailed solutions of specific technical problems which face engineers and technicians engaged in research and development in the fields of heat transfer and heat exchangers.
