Micro‐channel heat exchangers transfer more heat because of having a greater surface area compared to the conventional generation. This principle advantage can be applied widely in various industries for waste heat recovery purposes. Laser micromachining is a unique fabrication process, which presents some challenges. The main drawback of laser processes is introduction of residual stresses, which create distortion on the surface of heat‐affected areas. This study investigates some recent improvement in the fabrication methods of micro‐channel heat exchangers and concludes the strategies to control the distortion.
