METHOD OF MANUFACTURE OF SPACE APPARATUS THERMOREGULATING SYSTEM Russian patent published in 2017 - IPC B64G1/50 

FIELD: aviation.

SUBSTANCE: method of manufacturing thermal control systems (TCS) for space vehicles includes checking the total leakages of the liquid path and the dual-phase circuit (DFC) before refueling with their respective coolants. In the process of manufacturing DFC, an inter-cavity leakage between the vapour cavity and the liquid cavity of the capillary pump is additionally monitored with the test gas in the vacuum chamber, reporting the evacuated liquid cavity with the leak detector, providing a test gas with a pressure equal to the maximum working pressure of ammonia in the vapour cavity of the test gas. Before launching the spacecraft into orbit with the help of special software, the work of electric heaters of the volume compensator provides an increase in the minimum pressure at the entrance to the electric pump unit (EPU) to a certain value, guaranteeing nonconvulsive operation of the EPU with high reliability under operating conditions.

EFFECT: improving the reliability of the thermal control system of a spacecraft in conditions of prolonged operation in orbit.
