Microchannel Heat Sinks

Thermal management of electronic equipment is the primary concern in the electronic industry. Miniaturization and high power density of modern electronic components in the energy systems and electronic devices with high power density demanded compact heat exchangers with large heat dissipating capacity. Microchannel heat sinks (MCHS) are the most suitable heat exchanging devices for electronic cooling applications with high compactness. The heat transfer enhancement of the microchannel heat sinks (MCHS) is the most focused research area. Huge research has been done on the thermal and hydraulic performance enhancement of the microchannel heat sinks. This chapter’s focus is on advanced heat transfer enhancement methods used in the recent studies for the MCHS. The present chapter gives information about the performance enhancement MCHS with geometry modifications, Jet impingement, Phase changing materials (PCM), Nanofluids as a working fluid, Flow boiling, slug flow, and magneto-hydrodynamics (MHD).

The Mathematical Model

This study presents a parametric study of the two-dimensional steady-state keyhole model for high power density welding processes. Keyhole formation is common to electron beam welding, laser welding, and plasma arc welding, all of which are important techniques for high-quality, high-precision welding. Computation was performed by adopting a recently developed concept of the position correction and modifying it suitably for the problem of interest. The dimensionless parameters pertaining to the model were identified and the influence of each parameter was investigated separately. Although the mathematical model employed here has been used in previous studies, a thorough investigation successfully revealed new features that have not been previously recognized in the literature.
