Enhancement of the performance of a double layered microchannel heatsink using PCM slurry and nanofluid coolants

摘要: Advanced coolants such as nanofluids or PCM slurries are realized and reported effective substitutions for conventional in order to enhance the cooling performance of microchannel heatsinks. However, there a number disadvantages associated with using these advanced that always considered their inevitable downsides including increase needed pumping power system both mentioned decrease fluid average thermal conductivity slurries. In this paper, 3D conjugated heat transfer model double layer heatsink (MCHS) investigate its is presented effectiveness simultaneous employing types assessed. Finite volume method (FVM) used solve flow governing equations simultaneously obtained results validated experimental data. The assessed parameters study are: coolant type, configurations, particle concentration, bottom surface temperature, inlet velocity. efficiency heatsink, two dimensionless parameter, Nusselt Euler numbers, computed compared between configurations. goal balance optimize desirable enhancement by represented from one side, undesirable which implied relevant number, other side. Results showed proposed systems enhanced relieved, substantially.
