Computation of Thermal and Hydraulic Performances of Minichannel Heat Sink with an Impinging Air Jet for Computer Cooling

Résumé

This research work presents a numerical simulation of the CPU (Central Processor Unit) heat sink with a parallel plate fin and impingement air cooling. The governing equations are discretized by using the finite difference technique. The objective of this article is to investigate the thermal and hydraulic performances of a heat sink with impinging air flow to evaluate the possibility of improving heat sink performances. The numerical simulations are done by a personal C++ developed code. The thermal and hydraulic characterization of a heat sink under air-forced convection cooling condition is studied. The hydraulic and thermal parameters, including velocity profiles, the distribution of static pressure, pressure drop and temperature distributions through the fins, the base heat sink and the heat sink body through the heat sink are analyzed and presented schematically. The results show that the heat transferred by the heat sink increases with impinging Reynolds number. The performance of the proposed model computed by the numerical calculation is high compared with literature results.
