ABSTRACT
Today, microchannels are widely used in various fields, leading to the need for different and new requirements for microchannels during practical applications in terms of operating conditions, working fluids, and structure. Micro-channels exhibit remarkable heat transfer properties, enabling them to efficiently dissipate extremely high heat fluxes within confined spaces. The generation of large quantities of heat within a compact area in optical and electronic devices has led to advancements in microelectromechanical systems (MEMS). Microchannel heat sinks (MCHS) have been introduced to absorb high heat fluxes, which enables these devices to perform properly. This study aims to examine how an advanced ultra-high-temperature ceramic material, Hafnium diboride (HfB2), responds to normal heat flux conditions. The finite element approach was used to solve the governing equations for the solid (HfB2) and liquid (water) domains. The primary factors contributing to the elevated rate of heat transfer are that HfB2 is a good thermal conductor and that each microchannel volume has a large amount of heat transfer surface area. HfB2 exhibits intriguing thermal characteristics and possesses high-strength properties as an ultrahigh-temperature ceramic. The numerical analysis of a microchannel heat sink with extremely high heat flux, constructed using HfB2, is conducted using the finite element method. At the exceptionally high heat flux of 3.6 MW/m2, the maximum temperature of the wall was determined to be 360 K.
