In order to overcome the disadvantage of large pump power required to maintain flow with the large flow resistance caused by high viscosity and high density of liquid metal in microchannel heat sink, a new top-slotted microchannel is designed in this paper. The flow and heat transfer performance of microchannel heat sink with different slot heights was studied by numerical simulation. The results show that the lowest pump power of 0.00157W is obtained when the slot height is 0.8mm without affecting the cooling performance of the microchannel heat sink, which is 16.5% lower than that of the traditional channel.
