Heat Exchangers
What is a Heat Exchanger? Put simply, a heat exchanger is a device that transfers heat from one medium to another, a Hydraulic Oil Cooler for example will remove heat from hot oil by using cold water or air. Alternatively, a Swimming Pool Heat Exchanger uses hot water from a boiler or solar-heated water circuit to heat the pool water. Heat is transferred by conduction through the exchanger materials that separate the used mediums. A shell and tube heat exchanger passes fluids through and over tubes, whereas an air-cooled heat exchanger passes cool air through a core of fins to cool a liquid. Types of Heat Exchangers Heat exchangers are divided into various types based on different criteria. On the basis of the nature of the heating process: (a) Direct contact(open) heat generators Direct contact heat exchange takes place between two process streams. The streams can include combinations such as gas-solid, gas-liquid, liquid-liquid, liquid-solid, or solid-so...
