Abstract
A variant of a radiant cooler made of aluminum alloy and having anti-meteoroid protection of the tube with a coolant in the form of a bumper, which is a radiating surface, is presented. An approximate method for calculating the steady thermal state and pressure losses in the device is developed. A prototype is made and tested. It is shown that the calculated and experimental data are in good agreement. A computational analysis of an efficient (efficiency parameter is equal to 3.27 kg/m2) protected (the probability of non-damage within two years is equal to 0.97) device made of aluminum alloy with a power of 570 kW is performed when the coolant is cooled from 250 to 110°C .
