There are provided a heat exchanger having a flat tube and a fin bonded together, without causing melting of a coating material covering the fin, and a method of manufacturing thereof. A heat exchanger includes: a flat tube having a flat cross-sectional shape and covered with an anticorrosive layer; and a fin bonded to the flat tube with a bonding agent on a first surface of the anticorrosive layer interposed therebetween, and covered with a coating material, the first surface of the anticorrosive layer having been roughened, and the bonding agent being fixed to the roughened first surface.

A heat exchanger includes a plurality of fins extending along upper and lower directions, and a flat tube extending crosswise to the plurality of fins. Each of the plurality of fins has a first side edge portion and a second side edge portion, the first side edge portion and the second side edge portion extending along the upper and lower directions. The flat tube has end portions in the longitudinal axis direction of the flat tube, the end portions including a first end portion and a second end portion. The first end portion is positioned closer to the first side edge portion than the second end portion is to the first side edge portion. Each of the plurality of fins includes at least one water guide portion formed at at least one of a position between the first side edge portion and the first end portion, and a position between the second side edge portion and the second end portion, the water guide portion extending in the upper and lower directions, a lower edge portion positioned below the flat tube in the upper and lower directions, and a protruding edge portion positioned below the water guide portion and protruding downwardly relative to the lower edge portion.

The heat exchanger is generally ring-shaped and includes a plurality of heat exchange modules (2), which are mutually independent, being distributed about the axis (A1) of the ring. The modules (2) are assembled with one another, being successively spaced apart in pairs, a space (E1) being created between two adjacent modules (2). At least one of the spaces (E1) receives at least one conductive heat-transfer element (7) extending between respective walls of at least two adjacent the modules (2) which are oriented facing one another.

A tube for use in a heat exchanger includes an upper portion, a base portion spaced from the upper portion, and a partitioning wall depending from the upper portion. The partitioning wall is bent away and spaced from the base portion in a first section of the tube to form a single flow channel within the tube along the first section. The partitioning wall contacts the base portion in a second section of the tube to form a partition separating a first flow channel from a second flow channel along the second section. The first section of the tube is configured for reception into an opening of a header tank of the heat exchanger.

A heat exchanger includes a plurality of flat heat transfer tubes and a header, wherein, in an interior portion of each of the plurality of flat heat transfer tubes, a plurality of upwind side channels and a plurality of downwind side channels are formed, the header includes a main body portion in which an interior portion space connected to the plurality of upwind side channels and the plurality of downwind side channels is formed, a partition member that divides the interior portion space into an upwind side space, and a flow inlet/outlet port that supplies a refrigerant to a lower part of the upwind side space, and, at a lower part of the partition member, a lower communication path that communicates the downwind side space and the upwind side space is formed.

A cyclone cooler device includes a housing that defines an interior channel elongated along a center axis. One or more of the fluid passage or configuration of an inlet end of the channel is shaped to induce a swirling flow of a cooling fluid within the channel while the channel is thermally coupled with one or more heat sources. The swirling flow of the cooling fluid removes thermal energy from and cools the one or more heat sources. During the swirling flow, the cooling fluid rotates around the center axis of the channel while also moving along the length of the center axis. The cooling fluid changes phases during the swirling flow to cool the heat source(s).

A multilayered material system includes at least one of a liner sheet and a cellular core, and a multilayered composite joined to the at least one of a liner sheet and a cellular core. The multilayered composite includes hollow microspheres dispersed within a metallic matrix material.

A cooling system includes a heat exchanger having one or more rows of multiple flat tubes, louvered fins disposed between pairs of flat tubes, and special header tube connections to form a counter flow heat exchanger. Heat exchangers having multiple rows may be placed near or close to the server racks and may be in fluid communication with an outdoor heat exchanger having one or more rows. A single-phase fluid is pumped through a fluid circuit or loop, which includes the heat exchangers at the server racks and the outdoor heat exchanger. The single-phase fluid circuit including the heat exchangers at the IT racks may alternatively be in thermal communication with a water circuit that includes an outdoor fluid cooler. The flat tubes can be formed tubes with one or more channels, or extruded tubes with multiple channels. The heat exchangers include header tubes/connections, which facilitate easy fabrication and connection between rows and inlet/outlet, and lower the pressure drop.

An air conditioning system includes a first system and a second system. The first system includes a compressor, a first heat exchanger, a second heat exchanger, an electronic control assembly, and a first throttle. The second system includes a first heat exchange assembly and a heat exchange member. The first heat exchange assembly includes a first channel and a second channel isolated from each other. A second communication port of the first channel is in communication with a second opening of the compressor or a second opening of the second heat exchanger. A first communication port of the heat exchange member is in communication with a first communication port of the second channel A second communication port of the heat exchange member is in communication with a second communication port of the second channel. The heat exchange member includes a heat dissipation surface in contact with the electronic control assembly.

Embodiments of the present disclosure are directed to a climate management system that includes a heat exchanger having a first set of microchannel coils fluidly coupled to a first circuit of the climate management system and a second set of microchannel coils fluidly coupled to a second circuit of the climate management system, where the first circuit and the second circuit are fluidly separate from one another, and where the first set of microchannel coils and the second set of microchannel coils are disposed in an alternating arrangement along a length of the heat exchanger such that the first set of microchannel coils and the second set of microchannel coils are interlaced in the heat exchanger.
