Phased array antennas, such as a multi-function aperture, are limited in performance and reliability by traditional air-cooled thermal management systems. A fuel-cooled multi-function aperture passes engine fuel through heat exchangers that surround the multi-function aperture to provide better heat transfer than can be achieved through air cooling systems. The increased heat transfer and thermal management results in a multi-function aperture with improved performance and reliability.

A heat exchanger manifold for use in a heat exchanger having a plurality of microtubes includes a receiving component for supporting and forming a seal about each of the plurality of microtubes and a circuiting component having at least one recessed channel for defining an enclosed flow configuration of a fluid of the heat exchanger. The receiving component is joined and sealed to the circuiting component such that an internal flow passage of the plurality of microtubes is arranged in fluid communication with the at least one recessed channel.

A heat exchanger with increased heat transfer capability is provided. The heat exchanger includes first and second end plates, tubes extending between the first and second end plates and fins disposed between the tubes. The heat exchanger is disposable within and differs in shape from a space defined between first and second walls such that end corners of the first end plate abut the first wall and a point of the second end plate abuts the second wall, the first wall diverges from the end corners of the first end plate to define a first open region and the second wall diverges from the point of the second end plate to define second open regions. At least one of the first end plate and the second end plates includes enhancements fluidly communicative with the at least one corresponding one of the first open region and the second open regions.

A heat exchanger for a motor vehicle may include a plurality of flat tubes for a first medium and two tube bottoms. The plurality of flat tubes may be aligned in a longitudinal direction and stacked spaced apart from one another in a stack direction to form a heat exchanger block. The plurality of flat tubes may each extend into the two tube bottoms. The heat exchanger may also include two guide plates which close the heat exchanger block such that a plurality of flow spaces for a second medium are delimited between the plurality of flat tubes. A plurality of depressions may be disposed in a longitudinal end region of one of the guide plates, may protrude into a respective flow space, and may follow a shape of the adjacent flat tubes area by area such that the at least one guide plate surrounds the plurality of flat tubes.

A vehicle heat exchange apparatus, including: a heat-exchanger provided rearward of a front-bumper formed with an air-intake-port, and having an air-inlet-member on a front-face of the heat-exchanger; and a passage-forming-member provided between the front-bumper and the heat-exchanger, and forming a passage for passing cooling-air from the air-intake-port of the front-bumper to the air-inlet-member of the heat-exchanger, wherein the heat-exchanger is provided inclined so that an upper-end-portion is positioned rearward of a lower-end-portion, the passage-forming-member has: a duct-member having: a top-member; a bottom-member facing the top-member; and a pair of side-members interconnecting the top-member and the bottom-member, and forming a part of the passage with a space enclosed by the top-member, the bottom-member and the pair of side-members; and a closing-member provided to close a gap between the top-member of the duct-member and the upper-end-portion of the heat-exchanger.
