Ventilated casing assembly and non-propulsive turbomachine equipped with an air / oil heat exchanger

Abstract

Ventilated housing and non-propulsive turbomachine assembly equipped with an air / oil heat exchanger. One aspect of the invention relates to an assembly (100) comprising a ventilated housing (110) and a non-propulsive turbomachine (120) housed within said ventilated housing, wherein: the turbomachine (120) has an air inlet casing (123) and a gearbox (125) cooled by an air / oil heat exchanger (130); the ventilated housing (110) has a first air inlet (111) for injecting cooling air (F1) into the ventilated housing and a second air inlet (112) for injecting a supply air stream (F2) into the air inlet casing (123); the air / oil heat exchanger (130) is housed within the cavity of the air inlet casing (123) of the turbomachine; and the oil in the air / oil heat exchanger... being cooled by the supply airflow (F2) circulating in the air intake casing,and the heated airflow (F5) from the air / oil heat exchanger being exhausted from the ventilated enclosure.
