Reference number : GC-2017-Q4-00121, amendment number : , agreement type : G, recipient legal name : Barron, Ronald (University of Windsor), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Advancements in light emitting diode (LED) technology have created new opportunities for automotive manufacturers to use LEDs_x000D_
in vehicle head and tail lights. Thicker plastic lenses and complex profiles are required to optimize the optical characteristics of_x000D_
LED lights. Plastic thickness is a concern for mass production because of the increased amount of heat that must be removed_x000D_
from the molten plastic before it leaves the mold. The cooling time for a plastic part that is 4-6 times thicker than normal can be up_x000D_
to 10 times longer than the traditional thinner part. The increased costs inherent with longer cycles currently make thick wall_x000D_
injection molded parts cost prohibitive for mass production._x000D_
Cycle times can be reduced by optimizing the cooling passages within the molds. The current practice is to drill a network of_x000D_
interconnected straight cooling lines that do not conform to the complex surface profiles of todays automotive styles. This_x000D_
prevents implementation of a conformal cooling strategy that consistently positions cooling lines along the complex profiles of the_x000D_
mold to optimize the heat transfer._x000D_
The research will initially investigate the heat transfer and fluid flow in straight and conformal cooling inserts through_x000D_
Computational Fluid Dynamics (CFD) and Heat Transfer simulations and analysis. Simulations will then be used to optimize the_x000D_
design of cooling passages to extract maximum heat from the surrounding material. Finally, multiphysics models will be developed_x000D_
to more accurately predict the thermal characteristics of the complete injection molding system., program purpose french : Advancements in light emitting diode (LED) technology have created new opportunities for automotive manufacturers to use LEDs_x000D_
