FIELD: transport. ^ SUBSTANCE: invention relates to gas supply cryogenic system incorporated with extra-vehicular suit to be used outside spacecraft. Heat exchanger to gasify fluid oxygen comprises cylindrical casing (1), cover (13) with inlet 11 and outlet unions for heat carrier (moist air) and manifolds (14, 15) and coolant (oxygen to be gasified) unions (9, 10). Pipeline (5) feeds moist air onto heat exchanger bottom (8) whereon distributing cylindrical barrel (6) is arranged. Coils (2), (3), (4) with tubes that make spatial spiral are arranged concentrically on each other and on casing and secured in manifolds (14), (15). ^ EFFECT: compact heat exchanger-converter with sufficient capacity for preset time interval. ^ 3 cl, 2 dwg |
