Question: 1 / 400

What is the main purpose of a heat exchanger?

To mix different fluids for chemical reactions

To transfer heat between two or more fluids without mixing them

The main purpose of a heat exchanger is to transfer heat between two or more fluids without allowing them to mix. This is crucial in many applications where maintaining the integrity of each fluid is important, such as in heating, cooling, and various industrial processes.

In a heat exchanger, one fluid (which may be hot or cold) transfers heat to another fluid through the walls of the exchanger, facilitating temperature changes in the fluids as needed for their respective systems. This heat transfer can happen through various methods such as conduction or convection, but the key aspect is that the fluids remain separate throughout the process.

By effectively managing the temperature of the fluids, heat exchangers play a vital role in improving energy efficiency in systems like HVAC, refrigeration, and chemical processing, helping to optimize performance and reduce waste.
