Abstract
The invention relates to a heat exchanger (10) for heat-exchange between a first fluid and a second fluid, comprising a membrane separating the two fluids and a heat-conductive element (17) in thermal contact with the membrane and with the first fluid, characterised in that said heat-conductive element (17) moves between an active position and an inactive position, such that the capacity of heat exchange with the first fluid is weaker in the inactive position than in the active position. The exchanger is applied, in particular, for the cooling of fluid in the secondary stream of a turbofan.
Claims10
A heat exchanger for heat exchange between a first fluid and a second fluid, comprising a membrane separating the two fluids and a heat-conductive element in thermal contact with both the membrane and the first fluid, said heat-conductive element (17) being movable between an active position and an inactive position such that the capacity of heat exchange with the first fluid is less in the inactive position than in the active position, wherein said element is prestressed in the active position and the transition from the active position to the inactive position is achieved by buckling of the membrane.
