It is important to note that the fluids themselves never mix but instead are separated by the solid surface. This process has found wide application in the engineering world, but also in everyday household uses such as air conditioning and refrigeration. Probably the most well known heat exchanging device is a car’s radiator. Other examples include intercoolers, boilers, condensers, and also pre-heaters. heat exchangers, including a process of convection and conduction to function. In order to properly measure the operation of heat exchangers, both the efficiency as well as the size must be taken into account. Efficiency is most often rated by the measurement of the actual temperature change that both fluids experience, as well as the drop in pressure the heat exchanger evidences. The size of the heat exchanger is determined by the required temperature change forecasted, the speed at which this change is to be accomplished, as well as the allowable pressure drop. A lack of efficiency may point to improper operation of the device, while a sudden drop in efficiency is a clear sign of material failure or input/output strain. Other troubleshooting steps should include proper removal of chemical buildups. Heat Exchangers fall into a number of categories, name parallel-flow, counter-flow, and cross...
