The present invention provides a heat transfer equipment at rapid rate of thermal diffusion across the temperature gradient. The present invention further provides a method of manufacturing of a heat transfer equipment. The various embodiments of the present invention provide various methods for manufacturing of heat transfer equipment by affixing the loop or a solid member (201) containing crests and troughs on the surface of the central hollow member (101) by use of laser weld (301). The invention would provide much higher strength to the equipment and have much higher temperature sensitivity.

A heat pipe module includes at least one first pipe body and at least one second pipe body. The inner wall of the first pipe body defines a hollow chamber. A part of the second pipe body is disposed in the hollow chamber, and the external wall of the part of the second pipe body directly contacts the first pipe body.

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 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.

A heat exchanger includes a plurality of first members, and a plurality of second members located between adjacent first members of the plurality of first members. The plurality of first members each include a plurality of openings and a first flow path connected to the plurality of openings. The plurality of second members each include a second flow path connected to the openings of the adjacent first members. The plurality of openings and the first flow path of the first member, and the second flow path of the second member define a flow path for a first fluid. A region between the adjacent first members defines a flow path for a second fluid. The heat exchanger further includes a third member extending toward the region on the first member.

A heat exchanger (5) includes a plurality of flat heat transfer tubes (11) and a header (12), wherein the header (12) includes a first partition member (21) that separates an internal space of a main body unit (20) into a refrigerant inflow portion (24) and an upper portion (25), a second partition member (22) that separates the upper portion (25) into a connected portion (26) connected to the plurality of flat heat transfer tubes (11) and an opposite portion (27), and a third partition member (23) that separates the opposite portion (27) into a windward portion (28) and a leeward portion (29) a plurality of windward communication holes (35) and a plurality of leeward communication holes (36) that allow communication from the windward portion (28) and the leeward portion (29) to the connected portion (26) are arranged the second partition member (22) an adjustment channel (30) that distributes the refrigerant from the refrigerant inflow portion (24) to the windward portion (28) and the leeward portion (29) and that increases a flow rate of the plurality of windward communication holes (35) as compared to a flow rate of the plurality of leeward communication holes (36) is arranged in the header (12).

A heat exchanger includes: a heat exchange element including flat tubes spaced from each other; and a first header in which one end portion of each of the flat tubes is inserted. The first header includes: a first main header portion in which some of the flat tubes are inserted; a first sub-header portion in which others of the flat tubes are inserted such that the number of the flat tubes inserted in the first sub-header portion is smaller than that of the flat tubes inserted in the first main header portion; and a partition plate provided between the first main header portion and the first sub-header portion, and joined to the first main header portion and the first sub-header portion. The partition plate has a surface area that is larger than a sectional area of the first main header portion and a sectional area of the first sub-header portion.
