A thermal management system includes a heat exchanger and a housing that receives the heat exchanger. The heat exchanger defines a heat transfer region within which thermal exchange occurs between a process fluid and a thermal management fluid. The thermal management system further includes a process fluid conduit to convey the process fluid through the heat transfer region and an actuator assembly configured to position the heat exchanger relative to the housing. The actuator assembly is configured to selectively assume a position between a stowed position and a deployed position. When the actuator assembly is in the deployed position, the heat transfer region extends within a flow of the thermal management fluid such that the process fluid flow flows in heat exchange relation with the thermal management fluid flow. In some such embodiments, the actuator assembly automatically transitions between the stowed position and the deployed position.

A core-in-shell heat exchanger, a method of fabricating the core-in-shell heat exchanger, and a method of exchanging heat in a core-in-shell heat exchanger disposed on a slosh-inducing moving platform are described. The method of exchanging heat includes introducing a shell-side fluid into a shell of the core-in-shell heat exchanger and introducing a fluid to be cooled into each of one or more cores of the core-in-shell heat exchanger, the one or more cores being arranged along an axial length of the shell with a plurality of baffles disposed on either side of the one or more cores along the axial length of the shell to reduce slosh of the shell-side fluid. The method also includes draining excess shell-side fluid using a plurality of drains, at least two of the plurality of drains being disposed on opposite sides of one of the plurality of baffles.

Heat exchanger comprising circulation elements fluidically connected to one or more manifolds which are configured to feed a heat-carrier fluid in the circulation elements and to collect the heat-carrier fluid at exit from the circulation elements.

A cooling unit has a member-to-be-cooled, a duct, and a cushioning material. The member-to-be-cooled has a plurality of cooling fins. The duct is fixed to the member-to-be-cooled, has a partition wall facing the plurality of cooling fins, and conveys a fluid to around the plurality of cooling fins. The cushioning material is disposed between the partition wall and the plurality of cooling fins and fixed to the partition wall.

A deflector for a condenser. The condenser has an inlet in communication with a compressor, and a deflector for guiding a refrigerant gas flow from the compressor is arranged in the condenser and at a position close to the inlet. The deflector is provided with a deflecting structure projecting toward the inlet, and the deflecting structure is configured as impermeable to the refrigerant gas flow.

A heat exchanger assembly includes: a frame; a heat exchanger panel mounted to the frame and configured to exchange heat with air flowing therethrough, the heat exchanger panel being disposed at an inclined orientation; a fan assembly disposed vertically above the heat exchanger panel; and a sound dampening device disposed within an interior space of the heat exchanger assembly such that air is pulled into the interior space through the heat exchanger panel and then flows through the sound dampening device before being discharged from the heat exchanger assembly via the fan assembly. The sound dampening device includes baffle members having sound absorbing material and spaced apart from one another for allowing air flow therebetween. Each baffle member extends at an angle relative to a plane extending through the upper and lower ends of the heat exchanger panel so as to direct air flow upwardly toward the fan assembly.

A heat exchanger comprising a body part and a cooling fin system having an inlet end and an outlet end. The cooling fin system has a plurality of cooling fins, and is adapted to provide a flow path for a coolant flow through the cooling fin system in a longitudinal direction. The coolant flow is adapted to enter the cooling fin system through an inlet surface of the cooling fin system. The inlet surface of the cooling fin system is a non-planar surface.

A heat exchanger assembly includes a heat exchanger panel disposed at an inclined orientation. A fan assembly is disposed vertically above the heat exchanger panel and includes a fan impeller connected to a fan mount. The fan impeller is sized and positioned such that part of the fan impeller rotates vertically above the upper end of the heat exchanger panel. A casing has a plurality of inner walls for guiding air from the heat exchanger panel toward the fan assembly. The inner walls include a sloped wall. A distance between an upper end of the sloped wall and a fan rotation axis is greater than a distance between a lower end of the sloped wall and the fan rotation axis. The sloped wall is adjacent to the upper end of the heat exchanger panel such that the part of the fan impeller rotates vertically above the sloped wall.

A heat exchange and noise reduction panel the panel for an aircraft comprising: an external surface intended to be swept by an airflow and from which fins extend along a first and a second main predetermined direction; cavities forming Helmholtz resonators, linked to the first ends of channels for the passage of air, the second ends of which communicate with said airflow, such that said channels form necks, referred to as Helmholtz resonators, extending substantially along the first direction; and at least one oil flow chamber extending between said external surface and said at least one cavity, and intended to discharge the thermal energy carried by the oil, wherein said channels are formed, at least in part, inside said fins.

A method of passively suppressing noise within a heat exchanger comprises the steps of preselecting a plurality of sound wave travel distances formed between a plurality of surfaces within the heat exchanger to cause destructive interference of a preselected set of sound waves as the sound waves travel the preselected sound wave travel distances and assembling the heat exchanger to have the preselected plurality of sound wave travel distances formed between the plurality of surfaces formed within the heat exchanger.
