cooling system using a heat exchanger and antifreeze
being cooled by liquid nitrogen

The article describes the construction of the propellant cooling system using a heat ex-
changer and the antifreeze being cooled by liquid nitrogen, when the heat exchanger is
placed directly in the tank with antifreeze.
Cooling is performed by the circulation of
propellant from the tank of its location through the heat exchanger placed in the tank
with antifreeze being cooled by supplying dispersed liquid nitrogen. We present
the cool-
ing system circuit, equations and the results of predicting its efficiency in terms of the
relative liquid nitrogen flowrate in comparison with other variants of propellant cooling
on the space launcher complexes.
Keywords:
propellants, temperature preparation, cooling, heat exchanger, antifreeze,
liquid nitrogen, cooling efficiency.
