Numerical investigation of the effects of geometric structure of microchannel heat sink on flow characteristics and heat transfer performance

Numerical investigation on the electronic components' cooling for different coolants by finite element method

“…Increased size and power demands leading to higher running expenses restrict the use of active cooling methods. Moreover, the cooling capacity required to remove the huge amount of heat produced in confined passages of electronic devices can no longer be obtained through conventional air convection cooling 15 . It ensures that more advanced cooling methods and previously untested materials and coolants have to be constantly utilized, such that heat can be dissipated more efficiently, ensuring that the operating temperatures remain below the prescribed critical limit.…”

“…Investigations of heat transfer characteristics with various heat sink configurations have been carried out both theoretically and practically in microchannels and minichannels, respectively, by Al‐Neama et al 14 and Ghasemi et al 5 Mathew and Hotta 1 employed a hybrid optimization technique to discover an optimum arrangement of IC chips on the substrate board and found that the size and position of the chips strongly dictate the heat transfer characteristics. Later, a detailed analysis of the thermal and flow characteristics inside a microchannel heat sink for a lithium‐ion battery has been performed by Bayrak et al, 15 implementing different geometric modifications. Mohapatra and Loikits 16 compared thermal and hydrodynamic properties of six distinct commercially available liquids and concluded that PF/water solution gives the best overall performance.…”

Fluid flow and heat transfer in microchannel heat sinks: Modelling review and recent progress

“…The comparison between experimental data and numerical results proved that the ability of CFD to effectively simulate the concentration gradient of microchannels over a wide range of flow rates. Bayrak et al [18] established a two-dimensional modle and numerically investigated the effect of surface modification on the heat transfer performance of different MCHS in cooling channels of lithiumion batteries. Their research results showed that the combination of cavity and rib in microchannel has good heat transfer performance.…”

Ionanofluid flow through a triangular grooved microchannel heat sink: Thermal heightening

“…The vortices within the grooves offer significant advantages as a structure that enhances thermal transfer efficiency at higher Reynolds numbers and allows for a smaller pressure decrease at lower Reynolds numbers ( Re ). Statistical processing is used to assess how geometries affect the movement of liquid and transfer of heat properties in MCHS [ [32] , [33] , [34] , [35] ]. There have been numerous patterns for cavities and ribs, including zigzag cavities MCHS [ 32 ], rectangular cavities and ribs [ 33 ], triangular, rectangular, and trapezoidal microchannels [ 34 ], sinusoidal cavities and rectangular ribs [ 36 ].…”

“…Chen et al [ 34 ] claim that the triangle-shaped microscopic channel maintains the highest thermal efficacy. The most effective heating efficiency is found in the microchannel heat sink with a symmetrical cavity and rib (MC-SCR), according to Bayrak et al [ 35 ]. In addition to heat transmission, Ghani et al [ 36 ] concentrated on pressure drop and performance factors and discovered a performance parameter of 1.85 at Reynold number 800.…”
