Moving from air-to-air cooling to liquid-to-air cooling will impact geometry and part requirements for ducts, by whom/when the ducts are designed and in what fashion the ducts are secured to mating components. Also, manufacturers will want to find materials that will enable weight reduction via metal and rubber replacement, increased engine efficiency, emission reduction, noise reduction, a higher safety level, plus, a system cost reduction.
There is a technology specifically invented for elevated continuous-use temperatures of 180-230°C—a material that offers long-term heat ageing performance at elevated temperatures, higher peak temperature and performance and better chemical resistance. Diablo technology, invented and patented by DSM, improves the long-term temperature resistance of materials, such as Stanyl PA46 and Akulon PA66.
Compared to first generation Diablo offerings, Stanyl Diablo HDT2700 has an improved Heat Deflection Temperature (HDT), which is an indicator of peak temperature capability. Stanyl Diablo HDT2700 also offers best-in-class weld strength and ensures part integrity under pressure pulsation loads. It maintains high stiffness, even while exposed to continuous-use temperatures up to 230°C tested up to 3,000 hours.
There are also new Akulon Diablo materials—Akulon Diablo HDT2505 BM and Akulon Diablo HDT2504 BM. Both offer best-in-class heat aging performance that covers a wide temperature spectrum, impressive strength that enables thinner wall and part mass reduction, and a robust processability to help ensure a low scrap operation.
