In this study, the task of optimizing the supercomputer CPU cooling system with a heat pump in the reverse Stirling cycle through numerical modeling of heat transfer processes in the test object The article presents numerical modeling of heat transfer processes in the cooling system of the supercomputer processors with a heat pump on the return cycle. We investigated the numerical model of heat transfer process in the system of CPU "cold" cylinder and heat pump system "hot cylinder" - coolant. As a result, obtained according to the thermal resistance of the system of CPU "cold" cylinder and heat pump system "hot cylinder" - coolant depending on the coefficient of heat transfer and on the value of COP of the heat pump

Keywords: processor, heat flow, the thermal resistance of the Laplace equation, heat pump, heat exchange, reverse Stirling cycle cooling system
