Abstract

Abstract Currently, the flow channel shape of double-layer flat microchannel heat sinks is mostly rectangular. It is still unknown, though, how different channel forms affect how well microchannels dissipate heat. This study used numerical simulation software COMSOL to simulate the double-layer flat microchannel heat dissipation structures of rectangular (MC-DLRC), staggered rectangular (MC-DLCFRC), circular (MC-DLCC), semi-circular (MC-DLHRC), and trapezoidal (MC-DLTC) and obtained the optimal microchannel flow structure. The results show that the overall performance of trapezoidal double-layer flat microchannels (MC-DLTC) has been significantly improved compared to rectangular double-layer flat microchannels (MC-DLCC). PEC is increased by 17.68-29.45%. Research was conducted on the bottom angle of trapezoidal microchannels, and the differences between vertical and staggered arrangement of microchannels were also studied.
