TL;DR: In this paper, the authors investigated the thermal performance of two different types of wavy channels and their thermal performance for a constant heat flux of 47 W/cm 2 was compared and the best configuration considered in this paper was found to provide an improvement of up to 55% in the overall performance compared to microchannels with straight walls and hence are attractive candidates for cooling of future high heat flux electronics.
Abstract: Wavy channels were investigated in this paper as a passive scheme to improve the heat transfer performance of laminar fluid flow as applied to microchannel heat sinks. Parametric study of three-dimensional laminar fluid flow and heat transfer characteristics in microsized wavy channels was performed by varying the wavy feature amplitude, wavelength, and aspect ratio for different Reynolds numbers between 50 and 150. Two different types of wavy channels were considered and their thermal performance for a constant heat flux of 47 W/cm 2 was compared. Based on the comparison with straight channels, it was found that wavy channels can provide improved overall thermal performance. In addition, it was observed that wavy channels with a configuration in which crests and troughs face each other alternately (serpentine channels) were found to show an edge in thermal performance over the configuration where crests and troughs directly face each other. The best configuration considered in this paper was found to provide an improvement of up to 55% in the overall performance compared to microchannels with straight walls and hence are attractive candidates for cooling of future high heat flux electronics.

TL;DR: In this article, the authors apply the constructal method to the discovery of the optimal distribution of discrete heat sources cooled by laminar natural convection, where the global objective is to maximize the global conductance between the wall and the fluid or to minimize the hot-spot temperatures when the total heat generation rate and global system dimensions are specified.
