Engine assembly part for aircraft, has cooling system with heat pipe with evaporation end mounted on hot portion e.g. valve, to be cooled and condensation end mounted on front end of casing of part, where system cools hot portion

摘要

#CMT# #/CMT# The part has a hot portion e.g. valve (52), to be cooled and a cooling system to cool the hot portion. The cooling system has a heat pipe (54) with an evaporation end (54a) mounted on the valve and a condensation end (54b) mounted on a front end (24a) of a casing of the part. The heat pipe transfers the heat from the valve towards the casing. The end carries fixed blades (26) connecting the case to a fan casing (22) of a turbo machine. #CMT#USE : #/CMT# Engine assembly part for an aircraft (claimed). #CMT#ADVANTAGE : #/CMT# The heat pipe avoids the heating of the hot portion without realizing specific sampling of secondary flow and without loss of charges, thus largely increasing the performance of the engine assembly without increasing encumbrance of the engine assembly part. The part maintains coolness of the engine assembly without using pump or other mechanical artifice. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an engine assembly part. 22 : Fan casing 24a : Front end 26 : Fixed blades 52 : Valve 54 : Heat pipe 54a : Evaporation end 54b : Condensation end.
