A layered diffuser-channel heat exchanger may comprise a plurality of fluid channel layers and a plurality of diffuser fin layers interleaved with the plurality of fluid channel layers. Each fluid channel layer of the plurality of fluid channel layers may have a first surface, a second surface opposite the first surface, and a fluid channel located between the first surface and the second surface.

A heat exchanger has: a heat transfer tube group made up of plural heat transfer tubes each of which has, inside the heat transfer tube, a flow passage through which refrigerant flows; a fin provided on the heat transfer tubes; and a bridging header into which end portions of the heat transfer tubes are inserted and that causes refrigerant to flow between the heat transfer tubes. The bridging header has a base having a flat plate shape. The bridging header also has a corrugated sheet forming, between the corrugated sheet and the base, a header flow passage, through which refrigerant flows. The bridging header also has a covering plate covering the corrugated sheet and pressing the corrugated sheet toward the base.

The present invention relates to a heat exchanger and, more specifically, to a heat exchanger, which has a manifold coupled to a header tank, allowing easy attachment between a manifold and a header tank as well as avoidance of interference between the manifold and a support by forming a baffle-shaped fixed baffle on one length direction of the header tank to which the manifold is inserted and attached.

A heat exchanger is provided capable of exchanging heat received from a concentrated solar power plant via heat exchanging pipes and conducting the heat via patterns of flexible heat conducting cables into heat storing solids. The heat exchanger is further capable of exchanging heat stored by heat storing solids via the patterns of flexible heat conducting cables to heat exchanging pipes for use by a heat consumer. The heat exchanger has a charging and a discharging speed of a heat exchanger is about 50 kW/m.sup.3 or at least 50 kW/m.sup.3.

Systems and methods for providing a fin structure. The fin structure may be employed in a heat exchanger. The fin structure comprises: a support structure; and a plurality of fins disposed on the support structure via additive manufacturing so as to facilitate a change in direction of a fluid flowing through the fin structure. The fins comprise first fins that have centers arranged in accordance with a phyllotaxis or Fibonacci pattern.

In a heat exchanger, each of a plurality of heat exchange members includes: a flat pipe; and a heat transfer plate integrated with the flat pipe along a longitudinal direction of the flat pipe. A width direction of each of the flat pipes intersects with a direction in which the plurality of heat exchange members are arranged side by side. Each of the heat transfer plates includes an extending portion extending outward in the width direction of each of the flat pipes from at least one of one end of a corresponding one of the flat pipes in the width direction and another end of the corresponding one of the flat pipes in the width direction. Each of the flat pipes has one or more flat pipe bent portions, each forming a groove extending along the longitudinal direction of the flat pipes.
