摘要： A heat exchanger for a motor vehicle includes heat exchange bundle with a plurality of stacked tubes inside which a first heat-transfer fluid circulates, and an end flange arranged on each side of the stack of tubes which brazed to the heat exchange bundle. The end flanges include a flat body with a first surface that faces an aerodynamic element and a second surface, the brazing surface, opposite to the first surface and brazed to the heat exchange bundle. Attachment tabs receive the aerodynamic element and are arranged on the sides of the flat body, the attachment tabs projecting in the opposite direction to the heat exchange bundle. At least one extension of the flat body extends in the same general plane as the flat body and is arranged between a pair of attachment tabs on a same side of the flat body.

摘要： A multi-stacked heat exchanger comprises a first heat exchanger and a second heat exchanger. A first end of the first heat exchanger receives a first fluid in a first conduit flowing in a first direction within a plane. A first end of the second heat exchanger receives the first fluid from the first heat exchanger in a second direction flowing opposite to the first direction within the plane. A flow of a second fluid is communicated through the second heat exchanger and then through the first heat exchanger, in a second direction orthogonal to the first direction. The second fluid is in thermal communication with the first fluid in the second heat exchanger and then in the first heat exchanger. By doubling the flowed first fluid back upon itself, embodiments achieve counterflow between the first fluid and second fluid within a compact space.

摘要： A heat exchanger comprises a stack of sets of fins and tubes attached to or encompassed by embossed plates comprising a void. In some embodiments, the fins overlap the void having a peripheral margin of the fin attached to the peripheral margin around the void. In some embodiments, the fins comprise through fluid apertures allowing lateral fluid flow. In some embodiments, the plates comprise lateral peripheral protrusions enabling selective sealing of gaps between adjacent stacked plates by unselective application of heat or adhesive to a face of the heat exchanger. In some embodiments, the plates comprise uniformizing protrusions in a fluid inlet and/or outlet zone that reduce the amount of non-uniform fluid mass flow between different channel protrusions of heat exchanging zones of the set. Also disclosed are methods for assembly and selective sealing of the heat exchanger and an apparatus comprising the same.

摘要： Provided is an outdoor unit of an air conditioner, including: an outdoor heat exchanger that has a height longer than a width; and an outdoor blowing fan that is disposed above the outdoor heat exchanger and blows air upward from below the outdoor heat exchanger, in which the outdoor heat exchanger includes: a plurality of radiating fins that contacts air; a gap that is formed between the radiating fins; a louver fin that is cut in the radiating fin and then bent; and a cut-out area that is formed in the radiating fin and formed at a position where the louver fin is cut, the radiating fin includes: a first zone that is disposed above the outdoor heat exchanger and disposed close to the outdoor blowing fan; and a second zone that is located below the first zone, and an area LA1 of the louver fin in the first zone is formed to be larger than an area LA2 of the louver fin in the second zone.
The present disclosure has the advantage of uniformly forming air volumes in each zone of the heat exchanger in the vertical height direction by making the areas of the louver fins arranged in each zone different, even when the outdoor blowing fan is disposed to be biased upward.
