A heat exchanger is a heat transfer device whose purpose is the transfer of energy from one moving fluid stream to another moving fluid stream. Heat exchanger is a device in which heat is transferred between the hot and cold medium. The overall energy transfer is dictated by thermodynamics and the First Law.
Various heat transfer equipment is a common sight in many industrial plants and has a broad range of application in power stations, chemical and petrochemical processing plants, building heating and air conditioning, refrigeration systems, automotive industry, marine and space vehicles and electronic systems.
Heat exchangers can have different size and shape depending on the application, can be made of various materials and use various fluids for heat transfer
Different flow rates, different temperatures and different flow type efficiency were detected in this experiment. And calculations were studied with heat exchangers.
