In this study, the task is to simulate the cooling system of supercomputers with a heat pump on the reverse Stirling cycle by numerical simulation of heat transfer processes in the object under study. The results of numerical simulation of heat transfer processes in the superheater processor cooling system with a heat pump on the reverse cycle are presented. A numerical model of the heat transfer process was investigated. As a result, the dependencies of the required thermal lift of the heat pump are obtained taking into account the thermal resistance of the system. The first liquid cooling circuit - the cold cylinder of the heat pump and the hot cylinder system - the second liquid cooling circuit, depending on the heat transfer coefficient of the heat pump.
