Abstract Microchannel heat sinks have features-high heat transfer performance, compact structure, lightweight, easy to integrate packaging and so on, which are ideal to solve the cooling problem of aerospace engine. In this review, the manufacturing methods of microchannels are firstly introduced, and the manufacturing mechanisms and characteristics are analyzed and compared. The applications of microchannel cooling technology in aerospace field are then presented such as the microchannel cooling in the combustion chamber wall, precooler and turbine blade. Finally, the challenges of the microchannel cooling technology in the aerospace field are discussed.
