An overview of heat transfer enhancement methods in microchannel heat sinks
2023年10月5日 · The microchannel heat sink is widely used as an effective heat transfer method, which can achieve large heat flux cooling. However, conventional microchannel heat sinks have disadvantages, such as large wall superheat, low boiling critical heat flux, large pressure drop, and poor temperature uniformity.
Two-phase microchannel heat sinks offer several advantages over their single-phase counterparts. First, they can achieve far greater heat transfer coefficients by utilizing the coolant’s latent heat. This means a far smaller coolant flow rate is required to dissi-pate the same amount of heat as that of a single-phase heat sink,
