简介
The automotive lighting industry is adopting compact cooling systems for high power light emitting diodes (HPLED) to overcome the heating issues in headlamps. Today, nano-particle based fluids are becoming popular as coolants as it is more effective than conventional coolant like water. The present work uses nano-fluid which is prepared using 100 percent ethylene glycol with 35 nm spherical shaped alumina nanoparticle with 1 percent volume concentration for HPLED cooling system. Using a custom made copper tube heat exchanger, experiments were conducted to study the performance of the cooling system using nano coolant and double distilled pure water as second coolant and results were compared. A popular Indian SUV headlamp that uses a halogen bulb was chosen for the study as it has space to accommodate the cooling system. Experiments were conducted by operating the HPLED at its …
