Heat Exchanger

Abstract

Many of the various types of heat exchangers in automobiles are used to protect the engine components from overheating or to provide for passenger comfort. For this purpose, a great deal of the combustion energy needs to be released to the ambient air via the heat exchanger. Heat exchangers should not exert excessive flow resistance on the coolant to ensure that the coolant pump does not need too much power, which leads to pressure change between the outlet and inlet sides of the pump. Furthermore, the radiator structure must be mechanically strong. Last but not least, it must be possible to achieve large-scale production at an economic price.
