This paper investigates the convective heat transfer in a tube made of stainless steel 12X18H9T with outer diameter of 2 mm and inner diameter of 1.5 mm. For the research an experimental setup has been designed and assembled. The experimental setup consists of a fluid pumping system and flow-measuring device, working area, electrical power system and temperature measuring system. The experiment studies of heat transfer intensity in small diameter channels are performed. The study compares experimental data obtained with the theoretical ones. The paper presents the graphs of the Nusselt criterion dependence on the Reynolds criterion and the dependence of the convective heat transfer coefficient on the Reynolds criterion.
