This paper presents a consideration of micro‐heat exchangers design optimization for the aim of process intensification. Two examples are discussed to illustrate different ways of heat transfer intensification in micro‐heat exchangers. To solve the key issue of the link between the micro‐scale and the macro‐scale, a multi‐scale design optimization method using fractal and constructal approaches is introduced. The concept of a novel constructal heat exchanger is also proposed. Copyright © 2007 John Wiley & Sons, Ltd.
