Flow and thermal modeling of liquid metal in expanded microchannel heat sink

Frontiers in Energy 2023, Volume 17, Issue 6,   Pages 796-810 doi: 10.1007/s11708-023-0877-5

Abstract: The flow and thermal modeling of expanded microchannel heat sink (E-MCHS) were analyzed by both usingthe 3-dimensional (3D) numerical simulation and the 1-dimensional (1D) thermal resistance model.The fin efficiency of E-MCHS was derived to improve the accuracy of the 1D thermal resistance model.and the heat convection between the top surface of fins and the liquid metal could reduce the total thermalThe maximum thermal resistance reduction in the example of this paper reached 36.0%.
