Abstract

The antennas of modern radar devices need effective cooling, which is carried out by forced circulation of the coolant. A new pneumohydraulic diagram of a refrigerating unit, which allows achieving effective heat removal from an antenna of a radar station with minimal overall dimensions and weight, is considered in this paper. The paper presents the results of experimental research related to an operation of the refrigerating unit at ambient temperatures equal to +50 °C and -50 °C within the temperature range from −50 °C to 10 °C.
