FIELD: heating.SUBSTANCE: system for heating (50) of a cabin (2) in an aircraft (1) comprises a circular heat exchanger (10), placed around an exhaust pipeline (21) of a turbine engine (20) and where coolant (14) and ambient air (25) circulate. The heat exchanger (10) comprises a rear shell placed at the outlet of the heat exchanger (10) and guiding ambient air (25), exiting the heat exchanger (10), to exhaust gases (15), leaving the pipeline (21) of exhaust gases. Exhaust gases (15) provide for circulation of ambient air (25) in the heat exchanger by means of Coanda effect. Ambient air (25), circulating in the heat exchanger (10), is thus heated by convection from the pipeline (21), and coolant (14) is heated from one side by emission from the pipeline (21) and at the other side by convection between coolant (14) and ambient air (25).EFFECT: reduced losses of thermal engine capacity.14 cl, 3 dwg |
