A heat exchanger core includes a core formed such that a pair of adjacent passages are folded on top of one another while being adjacent. At least one passage of the pair of adjacent passages has a pair of adjacent passage portions between which the other passage is not interposed in a direction in which the passages lie on top of one another. The core has a heat insulation layer between the pair of passage portions.

Proposed is a heat dissipating device using turbulent flow. In the heat dissipating device, a plurality of block flow paths (12) are formed in parallel inside a block body (10), a first cap (16) and a second cap (28) are mounted on side surfaces (15) of the respective ends of the block body (10) so as to connect the block flow paths (12), a working fluid flows into the block flow paths (12), and the working fluid which has passed through the block flow paths (12) is transferred to the outside. Turbulence generators (38) are mounted inside the block flow paths (12), and finishing end portions (40) on the respective ends of the turbulence generators (38) are supported by the first cap (16) and the second cap (28) and are positioned inside the block flow paths (12).

A heat exchanger (100) includes a flow path layer (10) in which a first flow path (11) extending in a first direction and a second flow path (12) extending in a second direction are disposed in the same layer. In each of the first flow path and the second flow path, a flow path cross-sectional area is reduced and expanded along an extending direction of the flow path. The first flow path and the second flow path intersect each other in the same layer in first portions (23, 33) of which the flow path cross-sectional area is reduced, due to displacement of the first portions (23, 33) in a third direction.

The invention relates to a metal hydride hydrogen storage and supply arrangement integrated for use in a fuel cell utility vehicle. The storage arrangement includes a plurality of metal hydride containers suitable to be filled with a metal hydride material, the containers being connectable in parallel to a gas manifold; heat transfer means located between the metal hydride containers; and a filler body located in a space between the metal hydride containers and the heat transfer means.

There is disclosed a heat exchanger comprising: a plurality of first fluid channels, a plurality of conduits for interconnecting the first fluid channels, a plurality of second fluid channels, a plurality of conduits for interconnecting the second fluid channels, wherein the heat exchanger is configured as a plurality of repeating units, each repeating unit comprising: a base plate comprising a first opening, and a first conduit extending from the plate, the shape of the opening corresponding to the shape of the conduit.

A constant density heat exchanger is provided. The constant density heat exchanger includes a housing extending between a first end and a second end and defining a chamber having an inlet and an outlet. A first flow control device is positioned at the inlet of the chamber and movable between an open position in which a working fluid is permitted into the chamber and a closed position in which the working fluid is prevented from entering the chamber. A second flow control device is positioned at the outlet of the chamber and movable between an open position in which the working fluid is permitted to exit the chamber and a closed position in which the working fluid is prevented from exiting the chamber. A heat exchange fluid imparts thermal energy to the volume of working fluid held at constant density within the chamber by the first and second control devices.
