Disclosed herein is an integrated multiple heat exchange device and a fuel cell system using the same. The integrated multiple heat exchange device includes a plurality of heat exchangers for consecutively collecting heat contained in a plurality of gases that are present in the fuel cell system and that have different temperatures, wherein the plurality of heat exchangers are separated from each other, a porous separator is placed between the plurality of heat exchangers such that condensate is collected at a lowermost heat exchanger, and a coolant line penetrates a separator to pass through all the plurality of heat exchangers.

A heat exchanger, for example an intercooler or a coolant radiator, may include at least two floors each having a passage for accommodating a longitudinal end region of a plurality of fluid-conducting tubes. The heat exchanger may further include at least one side part having a longitudinal end region at least one of at least partially accommodated in a passage at an end of an associated floor and adjoining the associate floor. The at least one side part may include at least two segments having a different cross-section from one another.

A heat exchanger and methods of manufacturing and assembling a heat exchanger, and more particularly to an air-flow heat exchanger having a mechanically assembled header for use in a motor vehicle. The heat exchanger comprises an all-metal bonded matrix including a plurality of substantially parallel metallic tubes and a plurality of metallic fins. The tubes have a heat transfer portion that is elongate in cross-sectional shape, and which comprises two opposing, longer sides, and two opposing shorter sides. At least one of the tubes is mechanically joined at a first end portion thereof to a first header of the heat exchanger by at least one compliant member. The compliant member extends around the first end portion of the tube to provide a seal and to permit relative movement between the mechanically joined tube and the first header due to thermal expansion and contraction of the matrix.

A plate fin heat exchanger comprises a circular section tubular shell. The shell comprises a plurality of first shell openings arranged along a length of the shell and a plurality of second shell openings arranged along a length of the shell. A first fluid plenum is provided on the shell in fluid communication with the first shell openings. A second fluid plenum is provided on the shell in fluid communication with the second shell openings. The heat exchanger further comprises a core extending axially within the tubular shell. The core comprises an axially extending first core passage and a second axially extending core passage isolated from the first core passage.

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 exchanger includes a body, a plurality of first flow channels defined in the body; and a plurality of second flow channels defined in the body. The second flow channels are fluidly isolated from the first flow channels. The first flow channels and second flow channels are arranged in a checkerboard pattern.

Provided are a heat exchanger equipped with a cold reserving part and a manufacturing method thereof, equipped with a cold reserving part, in which since a cold reserving material charging part is formed at a portion at which an inlet and outlet member is formed, an additionally protruding part to inject the cold reserving material is not required, such that the heat exchanger may be miniaturized and may more rapidly and effectively absorb cold air to increase a cold reserving effect, and a manufacturing method of a heat exchanger equipped with a cold reserving part which forms the cold reserving material charging part to charge the cold reserving material after coating the heat exchanger to block a coating solution from introducing into the heat exchanger, thereby preventing the heat exchanger from corroding due to the coating solution to increase durability and more increase manufacturing performance.

A heat exchange device has a heat transfer member having thermal conductivity and a fin that is provided integrally with the heat transfer member. A heat transfer is performed between the heat transfer member and the fin. The fin is configured by more than one of a carbon nanotube aggregate that is configured by carbon nanotubes assembled together. The carbon nanotube aggregates are arranged on the heat transfer member and distanced from each other, and protrude from the heat transfer member in an axial direction of the carbon nanotubes.

Embodiments of the present disclosure are directed toward a heat exchange device that includes a first heat exchange unit having a first condenser tube bundle disposed within a first cylinder of the first heat exchange unit and a second heat exchange unit having a refrigerant dispenser disposed in a second cylinder of the second heat exchange unit, where a first refrigerant outlet of the first heat exchange unit is in fluid communication with a first refrigerant inlet of the second heat exchange unit through a throttling device, the refrigerant dispenser extends along an axial direction of the second cylinder to form a chamber within the second cylinder, the chamber includes an upper portion and a lower portion, a second condenser tube bundle is disposed in the upper portion of the chamber, and an evaporation tube bundle is disposed in the lower portion of the chamber.

A heat exchanger includes: a cooler/heater, an evaporator and a condensate separator, provided with inlet lines and outlet lines through which flows develop in countercurrent to each other for obtaining through the cooler/heater an incoming flow of hot and humid air and an outgoing flow of cooled cold air. The cooler/heater, the evaporator and the condensate separator are independent units from each other joined by a connection for defining a single-block body on whose outer surface inlet lines and outlet lines are provided. A first conduit places in communication the outlet line with the second inlet line; a second conduit places in communication the first outlet line with the first inlet line; and a third conduit places in communication the first outlet line with the first inlet line. The conduits project from the outer surface that delimits the single-block body.
