Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plants or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called engine coolant through the engine block and cylinder head where it is heated, then through a radiator where it loses heat to the atmosphere, and then returned to the engine. Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan[1] to force air through the radiator.
Unique Composition and Physical Characteristics Aluminum alloys incorporate aluminum and other metals (e.g., copper, zinc, manganese, magnesium), giving them low density and high strength—used extensively in aerospace, automotive, construction, and sports equipment. Excellent thermal and electrical conductivity also make them valuable for electronics and power transmission.
An inlet restrictor is a device placed inside the inlet of a fuel tank or radiator system to control or restrict certain functions. In automotive fuel systems, it has specific uses, but some systems can apply similar concepts to coolant systems as well. Here is a breakdown of its uses:
Not all oils are created equal, and the quality of the oil you use can influence the efficiency of the oils in cooling the engines. Here are some factors to consider:
Engine oil serves two primary functions: lubrication and cooling. These are interrelated roles because proper lubrication will also enhance the cooling that is required in most applications. Now let’s see how oil meets each of these functions:
When it comes to engine cooling, the picture that springs to the minds of many people is antifreeze circulating through the car’s radiator. However, one of the hidden gems in managing the engine temperature is not the coolant but the engine oil. Yes, the same oil that reduces friction between parts and prevents the metal to metal contact helps in the cooling of the engine. Indeed, if oil is not used at this capacity, engines will heat up much more and have a shorter lifespan; some might even seize up. Checking engine oil at our trusted auto repair shop helps maintain proper engine temperature and extends the lifespan of the vehicle.
