  • Patent number: 10415887
    Abstract: The present invention discloses a fin and a micro-channel heat exchanger. A retractable fin in a bending region of the micro-channel heat exchanger comprises a plurality of fin unit sections which are sequentially connected to form a corrugated structure, each fin unit section comprises a first straight section and an arc top section, and a retractable section which is deformed due to stretching/squeezing in a bending process of the micro-channel heat exchanger is provided between the first straight section and the arc top section. The retractable sections of the retractable fin are gradually straightened in the bending process of the micro-channel heat exchanger, included angles between the retractable sections and adjacent straight sections gradually become small, and this thereby ensures that the retractable fin in the bending region is not stretch-broken.

    Abstract: A method of fabricating a heat exchanger which includes: obtaining multiple coolant-carrying conduit sections, each having a non-circular cross-section, and first and second main surfaces; providing multiple primary folded fins secured to the conduit sections. Each folded fin includes a solid fin surface with multiple bends defining alternating, U-shaped air-passage channels, and a base surface and a top surface. Each folded fin is secured at the base or top surface to a main surface of a conduit section, and the folded fins have leading and trailing edges relative to airflow direction. The method includes forming a plurality of sets of secondary fins, each set extending from the leading or trailing edge of a respective folded fin at an angle other than 0. At least one conduit section has a first folded fin secured to its first main surface, and a second folded fin secured to its second main surface thereof.

  • Patent number: 7954237
    Abstract: A method for manufacturing a heat pipe and a capillary structure thereon is provided, and the steps of the method are as follows. A hollow pipe which has an open end and a closed end is provided. A mold is placed into the hollow pipe through the open end. The mold includes a central rod and a shaping component mating with the central rod, and the shaping component has an outward shaping surface. A powder is filled into the space between the hollow pipe and the mold through the open end and then sintered to form a capillary structure on the inner wall of the hollow pipe, in which the capillary structure has a profile corresponding to the shaping surface of the shaping component. Thereafter, the central rod and the shaping component are sequentially taken out of the hollow pipe.

  • Patent number: 7921559
    Abstract: A number of flat tubes, flat tube heat exchangers, and methods of manufacturing both are described and illustrated. The flat tubes can be constructed of one, two, or more pieces of sheet material. A profiled insert integral with the flat tube or constructed from another sheet of material can be used to define multiple flow channels through the flat tube. The flat tubes can be constructed of relatively thin material, and can be reinforced with folds of the flat tube material and/or of an insert in areas subject to higher pressure and thermal stresses. Also, the relatively thin flat tube material can have a corrosion layer enabling the material to resist failure due to corrosion. Heat exchangers having such flat tubes connected to collection tubes are also disclosed, as are manners in which such tubes can be provided with fins.

  • Publication number: 20110023522
    Abstract: An evaporator includes a cylindrical aluminum pipe, and two aluminum flanges which are fixed to both end surfaces of the aluminum pipe by screws. Screw holes into which screws are inserted can be formed in the wall of the aluminum pipe in a direction of the axis of the aluminum pipe simultaneously upon extrusion of the aluminum pipe. Communicating holes formed in the flanges communicate each set of two adjacent through holes among a plurality of the through holes formed in the wall of the aluminum pipe, thereby constructing one continuous coolant flow path inside the evaporator.
