A heat exchanger may include a three-dimensional lattice of integrally formed unit cells, a first furcated-pathway baffle integrally formed among the three-dimensional lattice, and/or a second furcated-pathway baffle integrally formed among the three-dimensional lattice. The three-dimensional lattice of integrally formed unit cells may include an interior pathway-cell surface contiguously defining a first furcated fluid domain, and an exterior pathway-cell surface contiguously defining a second furcated fluid domain. The first furcated-pathway baffle may contiguously define a first boundary to the first furcated fluid domain. The first furcated-pathway baffle may include an exterior baffle-cell surface contiguous with at least a portion of the exterior pathway-cell surface. The second furcated-pathway baffle may contiguously define a second boundary to the second furcated fluid domain. The second furcated-pathway baffle may include an interior baffle-cell surface contiguous with at least a portion of the interior pathway-cell surface.

Heat exchangers having a three-dimensional lattice structure

Provided are heat exchangers that have a plurality of integrally formed contiguous unit cells defining a three-dimensional lattice of repeating unit cells, and methods of reducing a pressure drop in a three-dimensional lattice structure of a heat exchanger. The plurality of integrally formed contiguous unit cells includes a plurality of pathway cells and a plurality of partial unit cells. The plurality of pathway cells have a solid domain that includes interior and exterior pathway-cell surfaces that respectively contiguously define first and second furcated fluid domains for a first fluid and a second fluid to respectively flow across the plurality of pathway cells. The plurality of partial unit cells may introduce a partial phase-shift to the three-dimensional lattice of repeating unit cells such that the first fluid domain comprises a first rounded unit cell entrance and the second fluid domain comprises a second rounded unit cell entrance.

Provided are heat exchangers that have a plurality of integrally formed contiguous unit cells defining a three-dimensional lattice of repeating unit cells, and methods of forming a baffle in a three-dimensional lattice structure of a heat exchanger. The plurality of integrally formed contiguous unit cells include a plurality of pathway cells and a plurality of baffle cells integrally formed among the plurality of pathway cells. The plurality of pathway cells have a solid domain that includes interior and exterior pathway-cell surfaces that respectively contiguously define first and second furcated fluid domains for a first fluid and a second fluid to respectively flow across the plurality of pathway cells. The plurality of baffle cells have a solid domain that includes one or more furcated-pathway blinds that together provide one or more furcated-pathway baffles that contiguously define a boundary to a furcated fluid domain.

Heat exchangers having a three-dimensional lattice structure with baffle cells and methods of forming baffles in a three-dimensional lattice structure of a heat exchanger

An apparatus and method of forming a heat exchanger can include a first manifold that defines a first fluid inlet to the heat exchanger and a second manifold that defines a second fluid inlet to the heat exchanger. A lattice cell body can be provided in the heat exchanger that can form a first set of flow passages and a second set of flow passages. The first and second sets of flow passages can be intertwined with one another.

Heat exchanger assembly

Display

A polymer blend comprising a polyalkylene terephthalate, an organopolysiloxane-polycarbonate block copolymer, and a halogenated copolycarbonate having improved impact, heat distortion and flame retardant properties. The polymer blends can be molded or formed into films, sheets, fibers, laminates, or other improved molded articles of manufacture, including reinforced articles by conventional techniques.
