A heat exchanger includes a first collecting pipe, a second collecting pipe and a number of flat tubes connected between the first collecting pipe and the second collecting pipe. The first collecting pipe includes a first upper main board and a first lower main board. A first channel and a second channel are formed between the first upper main board and the first lower main board. The second collecting pipe includes a third channel and a fourth channel. The third channel is communicated with the first channel through a row of the flat tubes. The fourth channel is communicated with the second channel through another row of the flat tubes.

A heat exchanger includes: a heat exchanging part that includes flat tubes aligned vertically when the heat exchanger is installed; a first flow divider that includes a first pipe through which a refrigerant enters or exits from the first flow divider, second pipes that provide refrigerant flow paths between the heat exchanging part and the first pipe, and a main body that internally has a first space; and second flow dividers that each internally include one of second spaces that provide refrigerant flow paths between the heat exchanging part and the first flow divider. The first space communicates with a first end of the first pipe and a first end of each of the second pipes and causes the refrigerant to flow from the first pipe into the second pipes or from the second pipes into the first pipe.

A heat exchanger includes a plurality of conduits that extend between a first endplate and a second endplate. A first manifold is coupled to the first endplate to couple the first manifold to first ends of the plurality of conduits. An inlet is coupled to the first manifold to direct a first fluid into the first manifold and at least one baffle is disposed within the first manifold to form a first cavity and a second cavity. The at least one baffle of the first manifold is configured to direct the first fluid from the inlet to a first conduit of the plurality of conduits. A second manifold is coupled to the second endplate to couple the second manifold to second ends of the plurality of conduits and at least one baffle is disposed within the second manifold to form a fourth cavity and a fifth cavity.

The present invention relates to a cold reserving heat exchanger, and more particularly; to a cold reserving heat exchanger capable of improving cooling comfortableness of a user and minimizing energy and a time consumed at the time of again performing cooling by storing a cold reserving material in a second-row tube among tubes disposed in three rows in a width direction and allowing a cooling fluid moving in a first-row tube and a third-row tube among the tubes to be movable between the first-row tube and the third-row tube to effectively store cold air of the cooling fluid and discharge the cold air at the time of stopping an engine to thus prevent a rapid rise in an internal temperature of a vehicle.

A heat exchanger including: a header; flat tubes connected to the header and disposed in line along a longitudinal direction of the header; a first partition that partitions an inner space of the header into a first space on a side where the flat tubes are connected and a second space on a side opposite to the first space; and a second partition that partitions the inner space of the header into a first side and a second side. The first side is one side of the header in the longitudinal direction and the second side is opposite to the first side. The first partition has a common opening. The common opening includes an insertion opening and a refrigerant opening. A refrigerant moves between the first space and the second space via the refrigerant opening. The second partition is inserted into the insertion opening.

A heat exchanger including a mixing and redistribution header (20) at one end of the heat exchanger; multiple heat exchange tubes (30) in communication with the mixing and redistribution header (20). An upper cavity (21) and a lower cavity (22) in communication with each other are disposed in the mixing and redistribution header (20); a fluid entering the heat exchanger first of all flows into a part of the lower cavity (22) of the mixing and redistribution header (20), then is collected and mixed in the upper cavity (21) of the mixing and redistribution header (20), and is distributed into another part of the lower cavity (22) and flows out through a heat exchange tube (30) in communication with the lower cavity, a cross-sectional area of the upper cavity (21) being equal to or greater than a cross-sectional area of the lower cavity (22).

A heat exchanger includes a plurality of tubes having refrigerant flowing therein and arranged to exchange heat with outside air; and a header having a chamber adapted to distribute the refrigerant to the plurality of tubes, wherein the header includes, a base wall having a plurality of tube insertion holes into which the plurality of tubes are inserted, and a partition wall integrally formed with the base wall and configured to divide the chamber into a plurality of sections corresponding to the plurality of tubes. This structure helps reduce the number of parts of the heat exchanger, simplify processing and assembling, and improving the heat transfer performance by improving the distribution of the refrigerant.

Provided is a heat exchanger including multiple fins, multiple heat transfer pipes having an oval shape or a flat shape and joined to the fins, and a header connected, on one end side, to an end portion of an inlet pipe through which working fluid flows in upon evaporation operation and connected, on the other end side, to an end portion of each of the heat transfer pipes, wherein the header includes a longitudinal partition plate arranged to extend in a longitudinal direction and configured to divide an internal space of the header into an inlet-pipe-side space connected to the end portion of the inlet pipe and a heat-transfer-pipe-side space connected to the end portion of each of the heat transfer pipes, and an opening is formed at a position not overlapping with the inlet pipe at the longitudinal partition plate.

A heat exchanger includes a plurality of flat tubes, a header part, and a guide part. An interior of the header part is partitioned into first and second spaces. One end of each of the tubes is connected to the first space. The guide part has a guide space positioned below the first space. The guide space communicates with the first space via an ascending opening. The first and second spaces communicate with each other via upper and lower communication ports provided within upper and lower sides of the header part, respectively. When the heat exchanger is viewed from above after installation, the tubes and the ascending opening have an area of overlap, and the ascending opening and a space where the lower communication port is extended do not overlap or have an area of overlap that is up to 50% of the ascending opening.
