Understanding Heat Exchangers

What is a heat exchanger and how does it work?

A heat exchanger is a device used in various industrial and residential applications to transfer heat from one medium to another. It plays a crucial role in maintaining optimal temperature levels in a variety of systems such as HVAC, refrigeration, and power generation.

The working principle of a heat exchanger is quite simple yet highly effective. It consists of two separate channels or passages through which two different fluids flow, without coming into direct contact with each other. The fluids may be gases, liquids, or a combination of both.

Heat exchange takes place as these fluids pass next to or through each other. One fluid, known as the “hot” fluid, transfers its heat to the other fluid, known as the “cold” fluid, resulting in a temperature exchange between the two. This heat transfer can occur through conduction, convection, or radiation, depending on the design of the heat exchanger.

Different types of heat exchangers and their applications

Heat exchangers come in various designs, each suited for specific applications. Here are some common types and their applications:
