The article is devoted to testing the thermal layout. The thermal layout includes an SLM-made body and thermal simulators. The article provides a thermal and hydraulic layout calculation. According to the results of the calculation, a graph of hydraulic losses and a table of temperature values at the control points depending on the flow rate of the coolant were obtained. Marked control points of measurement. It is given а brief description of the developed installation for testing. In the process of testing, the flow rate and temperature of thermal simulators were measured. Based on the measurement results, a table of the measured temperature versus the flow rate was compiled and a graph comparing the calculated and experimental values. Аanalyzing the results revealed a deviation from the calculated values of no more than 5%. Also proposed a form of pins inside the cooling channel to increase the area of the heat sink and reduce the hydraulic resistance. According to the results of calculations and tests, it can be said that the use of additive technologies for the production of shells and cooled bases of this kind is promising and justified from a technical point of view.
