cooling system

The demands on modern engine cooling systems are many and varied. Although increased performance, reduced fuel consumption, longer durability and lower emissions may appear to be at odds with other, the engine cooling supplier must address them all. Fuel economy pressures have long since driven innovation in the engine cooling arena, prompting engineers to consider alternatives to copper-brass, steel and plastics. Aluminium radiators for passenger cars and light trucks are not only lighter, thinner, easier to recycle and cheaper than their copper-brass counterparts but also demonstrate higher heat transfer performance and better durability. The actual size of radiators has gradually reduced too. A modern aluminium radiator is about two-thirds the size of a unit designed in the late 1970s. Manufacturers also predict future growth in smart engine cooling systems as the European auto industry moves towards meeting forthcoming emissions regulations. Developing power train cooling systems for hybrid and fuel-cell vehicles is another main thrust of new product development. Cooling systems are also becoming more modular, thereby lowering costs and simplifying installation.
