A method of tracking an engine cooler in an aircraft includes recording an orientation of the engine cooler as orientation N. Prognostic health management data of the aircraft is tracked. A maintenance check of the aircraft is performed based on the tracked prognostic health management data. Whether to rotate an orientation of the engine cooler is determined with an aircraft maintenance database based on the tracked prognostic health management data of the aircraft. A recommendation is provided by the aircraft maintenance database as to whether to rotate the engine cooler. The orientation of the engine cooler is recorded as orientation N+1.

The present application generally relates to a method and apparatus for providing an active heat exchanger with dynamic positioning to improve vehicle aerodynamics. More specifically, aspects of the present disclosure relate to systems, methods and devices for a vehicle fascia having multiple airflow openings, at least one of having an active shutter system and wherein the active heat exchanger is positioned to respond to closing of one or more of the airflow openings when active aerodynamics are deployed.

The invention relates to improvements of a heat exchanger, particularly a scraping heat exchanger having an outer cylinder comprising a first wall having a smooth circle-cylindrical inner side, and an inner cylinder positioned concentrically within it. The improvements regard a simple detachable inner cylinder, a heat exchanger with lid including a fluid barrier, a heat exchanger with a tangential output, and a method and heat exchanger adapted for improved evacuation of a product chamber of a heat exchanger.

According to one embodiment, a heat exchanger includes a pipe through which a fluid flows, and a supply device that supplies the fluid to the pipe. The pipe includes a flexible part deformed by flowing of the fluid, and a constricted part located at a downstream side of the flexible part along a flow direction of the fluid.

A heat exchanger arrangement includes a housing in which an air inlet opening is arranged on the circumference, a cover that covers the housing on an upper side and in which an air outlet opening is arranged, a reverse-operated radial fan being arranged inside the housing in such a way that it can generate an air flow between the air inlet opening and the air outlet opening, which air flow is directed radially inward with respect to the axis of rotation of the radial fan and which flows through at least one air heat exchanger arranged in the housing.
