heat rejection

Heat rejection is the process of removing excess heat from a system or object to maintain a desired temperature. For example, in electronic devices or engines, heat generated during operation needs to be expelled to prevent overheating. This is often achieved through methods like cooling fans, radiators, or heat sinks that transfer heat away from the source to the surrounding environment. Efficient heat rejection ensures optimal performance, safety, and longevity of machinery or systems by preventing temperatures from reaching harmful levels.
