摘要：

This paper conducted an experimental investigation on flow and heat transfer characteristics associated with the forced flow of de-ionized water in a periodical changeable cross-section micro-channel (PCMC) heat sink. The friction factor, Nusselt number, average temperature of heating film and thermal resistance of heat sink under different pump power were obtained. In comparison with traditional micro-channels with constant cross-section, the periodical changeable cross-section micro-channels could produce higher heat transfer coefficients and friction factors.
