An air conditioner including a distributor configured to distribute a fluid to a heat exchanger. The distributor comprises a main pipe; a partition defining a plurality of distribution paths in the main pipe; a first branched pipe inserted into the main pipe as much as first length, linked to a first distribution path of the plurality of distribution paths, connected to a first portion of the heat exchanger; and a second branched pipe inserted into the main pipe as much as second length different from the first length, linked to the first distribution path, connected to a second portion of the heat exchanger. A flow velocity of air exchanging heat at the first portion of the heat exchanger is faster than a flow velocity of air exchanging heat at the second portion of the heat exchanger. The first length is shorter than the second length.

A heat exchanger header includes a first inlet, a first passageway that fluidically connects the first inlet to a first outlet, a second inlet, and a second passageway. The second passageway fluidically connects the second inlet to a second outlet. The first inlet, the first passageway, and the first outlet are fluidically isolated from the second inlet, the second passageway, and the second outlet.

A heat exchanger having a heat exchanger core having at least two rows of tube and fin blocks, each tube and fin block contains an assembly of tubes and fins, wherein the tubes are aligned parallel to each other while the fins are located between adjacent tubes, each tube having a first tube end and a second tube end, each tube and fin block of the first tube and fin block and the second tube and fin block having a manifold tube, the manifold tubes having a row of openings for a fluid tight connection with tubes of a tube and fin block, wherein the first tube ends of the first tube and fin block are fluid tight connected to the openings of a first manifold and the first tube ends of the second tube and fin block are fluid tight connected to the openings of a second manifold.

A manifold for a heat exchanger includes a manifold body configured to house heat exchanger components including a blower for circulating air and means for performing heat exchange between the air and a heat exchange fluid. The manifold also includes an opening (A) via which air enters the blower, an inlet for receiving air from the heat exchanger and an outlet for outputting air from the manifold. The manifold also includes a flow channel extending between the inlet and the outlet. The channel defines a helical flow path from the inlet to the outlet.

A laminated header includes: a first passage plate having a flat-plate shape in which a first passage is formed; a second passage plate having a flat-plate shape in which a plurality of second passages are formed; a third passage plate having a flat-plate shape in which a plurality of third passages are formed; a first branch passage plate having a flat-plate shape in which an upstream side branch passage is formed, the upstream side branch passage branching the first passage into the plurality of second passages; and a second branch passage plate having a flat-plate shape in which a downstream side branch passage is formed, the downstream side branch passage branching one of the plurality of second passages into the plurality of third passages.

An assembly wedge for an oil cooler in a radiator tank includes a housing and a biased pin. The biased pin is disposed slideably within the housing and is configured to engage the oil cooler.

A fluid heating system including: a pressure vessel shell com including prising a first inlet; a heat exchanger disposed in the pressure vessel shell, the heat exchanger including a second inlet and a second outlet, wherein the second inlet of the heat exchanger is connected to the first inlet of the pressure vessel shell; and an exhaust manifold disposed in the pressure vessel shell, the exhaust manifold including a third inlet and a third outlet, wherein the third inlet of the exhaust manifold is connected to the second outlet of the heat exchanger, wherein the third outlet of the exhaust manifold is outside of the pressure vessel shell, and wherein the exhaust manifold penetrates the pressure vessel shell.

One method of operating a fuel cell system including splitting a cathode exhaust from one or more fuel cell stacks in the system into a majority cathode exhaust stream comprising more than 50% of the cathode exhaust and a first cathode exhaust bypass stream, providing the majority cathode exhaust stream to an inlet of an anode tail gas oxidizer (ATO) containing a catalyst and providing the first cathode bypass stream downstream of the catalyst such that it bypasses the catalyst. Another method includes providing an air inlet stream to the SOFC system via a main air inlet, providing the air inlet stream from the main air inlet to a cathode recuperator, and providing a cooling medium to a heat exchanger to cool the cathode recuperator.

A closure bar adapted for use in a heat exchanger core includes a center void region configured to be partially filled with a phase-changing material and sealed, thereby containing the phase-changing material. The phase-changing material is configured to change phase in a forward direction as the flow of hot fluid over the closure bar begins, thereby slowing a rate of a temperature increase by absorbing a latent heat as the phase-changing material changes phase in the forward direction, and change phase in a reverse direction as the flow of hot fluid over the closure bar ceases, thereby slowing a rate of a temperature decrease by liberating the latent heat as the phase-changing material changes phase in the reverse direction. A method of producing and using the closure bar is also disclosed.

An air conditioner including a distributor configured to distribute a fluid to a heat exchanger. The distributor comprises a main pipe; a partition defining a plurality of distribution paths in the main pipe; a first branched pipe inserted into the main pipe as much as first length, linked to a first distribution path of the plurality of distribution paths, connected to a first portion of the heat exchanger; and a second branched pipe inserted into the main pipe as much as second length different from the first length, linked to the first distribution path, connected to a second portion of the heat exchanger. A flow velocity of air exchanging heat at the first portion of the heat exchanger is faster than a flow velocity of air exchanging heat at the second portion of the heat exchanger. The first length is shorter than the second length.
