A heat exchanger core includes a medium inlet and a medium outlet for the heat transfer fluid to be cooled and a plurality of plates extending from a first end (A) to a second end (B) of the heat exchanger core and defining flow conduits therebetween from the medium inlet to the medium outlet. The core also has a plurality of fins between the plates for directing a coolant medium across the flow conduit. One of the flow conduits has a larger cross-section than the other flow conduits, and the inlet is provided at a first end of the one of the flow conduits adjacent the first end of the heat exchanger core, or between the first end and the second end.

A heat exchanger (10) includes an assembly of plates (12) stacked in pairs in a longitudinal stacking direction (x) to form a heat exchanger body (14), designed for the circulation of a fluid, comprising a connection device (19) arranged at one extremity of the heat exchanger body (14) in the longitudinal stacking direction (x). The connection device (19) includes an end plate (20) and a cover (22) that can be assembled together to jointly delimit an inlet duct (24) and an outlet duct (26), respectively, to admit the fluid into the heat exchanger body (14) and discharge the fluid from the heat exchanger body (14).

An expansion radiator for a hermetically closed electrical transformer or a throttle. A heat exchange fluid is delivered to the radiator via an inflow, passed through an expansion shaft cavity formed by an expansion shaft and an associated cover part, and then drained off via an outflow. A flow guiding part which steers a flow direction of the heat exchange fluid is arranged in a mouth region between the inflow and the expansion shaft cavity.

Each heat exchange tube of a condenser is formed of a first brazing sheet having a core material and a first brazing material covering the core material. The tank body of each header tank is formed of a second brazing sheet having a core material and a third brazing material covering the core material and being lower in flowability than the first brazing material. In a region of a surface of each protrusion portion facing the corresponding heat exchange tube, the region having a predetermined width as measured from the projecting end, the core materials of the two brazing sheets are brazed together by means of the first brazing material. In the region other than the brazed portion, the core materials of the two brazing sheets are brazed together by means of a fillet formed of a mixture of the first and third brazing materials.

A window assembly heat transfer system is disclosed in which a window member has a selected transparency to monitored or sensed light wavelengths. One or more passages are provided in the window member for flowing a single-phase or two-phase heat transfer fluid, the passages being optically non-transparent to the monitored or sensed light wavelengths. A mechanism allows either evaporation or condensation of the fluid and/or balancing of a flow of the fluid within the passages. In one embodiment, the window assembly can be made by producing passages in a top surface of a first single plate, optionally producing passages in a bottom surface of a second single plate and bonding the top surface of the first plate to a bottom surface of a second single plate to form the window member with the passage or passages. In another embodiment, the window assembly can be made by providing a core around which the window member material is grown and thereafter removing the core to produce the passage or passages.

A tube stay mounting assembly includes a press assembly having a housing and a top block configured to flatten fins on a first surface of a finned tube. A press arm is operable to move the top block vertically with respect to the housing. A bottom block is configured to flatten fins on a second surface of the finned tube when the press arm is rotated and moves the top block downwardly. A tube stay clamping assembly includes a clamping housing configured to receive a tube stay having a top, bottom, rear, and front walls, the tube stay being configured to receive a flattened portion of the finned tube. A clamping arm is connected by linking arms to a clamping block, the clamping block configured to engage and force the front wall into snap-fit engagement with the top wall of the tube stay.

A heat exchanger carries out heat exchange between a refrigerant that undergoes a phase change during heat exchange and another heating medium. The heat exchanger includes headers having the refrigerant flowing through interiors, a plurality of multi-hole first flat tubes, and a plurality of second flat tubes. The first flat tubes extend in a direction intersecting a lengthwise direction of the headers. The first flat tubes have a plurality of refrigerant flow channels with the refrigerant flowing through the refrigerant flow channels. The second flat tubes are stacked alternately with respect to the first flat tubes, with the other heating medium flowing through the second flat tubes. The headers are arranged to extend along a horizontal direction.

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, characterized in that wherein said channels are formed, at least in part, inside said fins.

A heat exchanger for an aircraft engine that allows improvement in heat exchange ratio is provided. The heat exchanger (1) includes a plurality of heat dissipating fins (20, 30). The plurality of heat dissipating fins (20, 30) are arranged on at least one of a surface (2) and a surface (3). Each of the heat dissipating fins (20, 30) has a plate-like shape and has an inlet-side upper edge disposed on the side where a swirl flow (AF1) flows in and an outlet-side upper edge disposed on the side opposite the inlet-side upper edge and on the side where the swirl flow (AF1) flows out, and the inlet-side upper edge intersects the axis of rotation of a fan and extends along the direction in which the swirl flow (AF1) flows at the inlet-side upper edge.
