counterflow heat exchanger

A counterflow heat exchanger is a device that efficiently transfers heat between two fluids flowing in opposite directions. Imagine warm water passing through pipes and absorbing heat from cold water flowing in the opposite direction inside a different set of pipes. By flowing in opposite directions, the two fluids maintain a consistent temperature difference along the exchanger, maximizing heat transfer. This setup is commonly used in heating and cooling systems, such as in power plants or HVAC systems, to improve energy efficiency by capturing and reusing heat effectively.
