The paper presents the results of an experimental study of heat transfer during forced water flow from microstructured surfaces in a slotted channel. The investigated micro-structured surfaces were obtained by a resource-saving (waste-free) method of deforming cutting with various constructive shapes and sizes. A description of the experimental setup, methods for conducting and processing experimental data are presented. The maximum increase in heat transfer coefficients in comparison with a smooth surface reaches Nu/Nu0 = 16.2.
