The invention relates to a combined heat exchanger (6) and fluid filter (9, 10) that can be used in a gas turbine engine for example to simultaneously filter lubricating oil (9) and fuel (10) while transferring ther-mal energy between the oil and fuel (6). Conventionally, fuel (10) and oil (9) filters as well as a heat exchanger (6) are separately mounted in an engine with a multitude of pipes conducting fluids between them. The invention packages these components together (1).
L'invention concerne un échangeur thermique (6) et un filtre pour fluides (9, 10) combinés, pouvant s'utiliser dans un moteur à turbine à gaz, notamment en vue de filtrer simultanément l'huile lubrifiante (9) et le carburant (10), tout en assurant le transfert d'énergie thermique entre l'huile et le carburant (10). Les filtres à carburant (10) et à huile (9), de même qu'un échangeur thermique (6), sont généralement montés séparément dans un moteur, avec plusieurs conduites acheminant les fluides de l'un à l'autre. L'objet de la présente invention est donc de regrouper (1) ces composants.
