“…Regarding forced convection, this process has been largely studied in traditional fields like for the cooling of turbine blades [1] or for promoting heat transfer in nuclear reactors. In addition to these well-established and extensively-studied areas, newer engineering applications have been lately investigated, like solar collectors [2] or more recently for automotive batteries cooling [3] and high-performance CPU cooling [4,5]. These novel industrial applications that require heat exchangers with large contact areas and very small heights can benefit from the use of ribs to enhance heat transfer associated to high aspect ratio rectangular channels with ribbed surfaces [6].…”

A numerical analysis of heat transfer characteristics of an air flow through a narrow rectangular channel of 1:10 aspect ratio with ribbed surfaces has been carried out, by means of a CFD commercial code, exploiting Reynolds Averaged Navier-Stokes (RANS) equations. The channel is 120 mm wide, 840 mm long, with 60° tilted staggered ribs. Ribs have a square cross section with two different side heights (2 mm and 4 mm) and three different values of dimensionless pitch (10, 20 and 40). The numerical results have been compared with experimental data obtained by the authors inside a ribbed channel both with same geometry and operating conditions as one numerically modelled. Agreement between numerical and experimental data on convective global heat transfer coefficient, i.e., averaged over the whole channel, is discussed for the six different configurations considered. Moreover, performances are presented by considering at the same time both heat transfer enhancement and pressure-drop penalization, highlighting strengths and weaknesses per each configuration. This work is aimed at finding a suitable configuration of a CFD model with RANS that will allow authors to apply it to the range of dimensionless pitches and side heights during early design-phases of parametric studies.

“…The performance of microchannel heat exchangers in lithium-ion batteries was investigated by Liu et al [68], who also developed an original tree-shaped heat sink structure. Based on mini-channel heat sinks, Deng et al [69] developed a dual-sided heat dissipation system for high-power devices. Then they employed numerical simulation to optimize the structure of the microchannel and conducted experiments to verify the heat dissipation capacity.…”

With the rapid development of the electronics industry, the power of devices continues to rise, and seeking more efficient cooling technologies has become a key challenge in various applied scenarios. This study contributes to a novel and efficient heat dissipation method for chips employing liquid metal as a coolant. In this paper, the flow and heat transfer performance of a novel liquid metal (Ga61In25Sn13Zn1) in a mini-channel heat sink is conducted. Using pressure difference, pump power, and total thermal resistance as object parameters, a comprehensive optimization about Hp (channel height), Wc (channel width), Ww (wall thickness), and tb (base thickness) is presented. The optimized parameter combination is Hp = 7 mm, Wc = 0.6 mm, Ww = 0.4 mm, and tb = 0.2 mm. Furthermore, all of the optimization parameters are verified through the design method of orthogonal experiments.
