A heat exchanger is a device used to transfer heatbetween two or more fluids. … Another example is theheat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

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. The most well known type of heat exchanger is a car radiator.

As the water pumps through the pipes, it absorbs the heat energy and heats up. … A heat exchanger is a device that allows heat from a fluid (a liquid or a gas) to pass to a second fluid (another liquid or gas) without the two fluids having to mix together or come into direct contact.

They are used as components of air conditioning and cooling systems or of heatingsystems. … Within industrial plants and factories heat exchangers are required to keep machinery, chemicals, water, gas, and other substances within a safe operating temperature.

The method, at this point, is concerned only with the fluid undergoing the maximum temperature change. The effectiveness ( ), is the ratio between the actual heat transfer rate and the maximum possible heat transfer rate: where: Effectivenessis dimensionless quantity between 0 and 1

The thermal capacity of a heat exchanger is its ability to transfer heat between two fluids at different temperatures. It is a function of the heat exchanger design and the fluid properties on both sides
