Engine Cooling

Heat Exchangers

Engine heat exchangers play an essential role in cooling different components of an engine, such as glycol (engine coolant), oil, and charge air. Glycol cooling is critical for maintaining the engine's temperature within optimal limits, preventing overheating and subsequent damage. In this process, the heat exchanger transfers heat from the hot glycol to a cooler medium (usually air or water). Oil coolers, another type of heat exchanger, are designed to cool engine or transmission oil. They work by circulating the oil through a series of tubes or plates, where it loses heat to the surrounding air or coolant. Charge air coolers, also known as intercoolers, cool the air compressed by turbochargers or superchargers before it enters the engine, increasing its density and thereby enhancing combustion efficiency. These heat exchangers use either air or water as the cooling medium. These different types of heat exchangers are crucial for maintaining the performance, efficiency, and longevity of the engine.
