| The engineering background of the study on heat transfer in micro-scale channels is related in this paper. A generalization is presented for the investigations on the characteristics of flow and boiling heat transfer in micro-scale channels at home and abroad. Some influence factors on the flow boiling heat transfer in micro-scale channels, such as different test materials, geometries of micro-scale channels, and different test conditions, are especially discussed. At the same time discussions are made on the mechanism of heat transfer, the flow resistance characteristics, the correlation of pressure drop, and on the theoretical and experimental investigations of the correlation of boiling heat transfer in micro-scale channels. In addition, suggestions for the future work on flow boiling heat transfer in micro-scale channels are offered. |
