Water-cooled systems use water to absorb and dissipate heat, making them effective for cooling various machines and engines. This method is commonly found in vehicles, where radiators circulate water to maintain optimal operating temperatures, preventing overheating. In industrial settings, water-cooled systems are used in power plants and manufacturing processes to regulate temperatures in equipment. By transferring heat away from hot components, these systems enhance efficiency and prolong the lifespan of machinery, ensuring safe and reliable operation.
