Heat Exchange

Heat exchange refers to the transfer of thermal energy between different substances or systems. This process occurs whenever there is a temperature difference; heat flows from the hotter object to the cooler one until they reach equilibrium. This concept is fundamental in various applications, such as heating and cooling systems, engines, and refrigerators. Heat exchangers, devices designed specifically for this purpose, facilitate the efficient transfer of heat without mixing the involved substances. Understanding heat exchange is essential in fields like engineering, meteorology, and environmental science, as it influences energy efficiency and climate patterns.
