  • Patent number: 9604328
    Abstract: A heat sink structure and a method of manufacturing same are disclosed. The heat sink structure includes a main body and a plurality of radiating fins. The main body has a plurality of coupling flutes circumferentially spaced along an outer surface thereof and longitudinally extended from a first end to a second thereof. The radiating fins respectively have a bent section integrally located between a first and a second heat radiating section. To quickly assemble the radiating fins to the main body, the radiating fins are disposed in a forming mold, and the main body is mechanically driven into the forming mold at a high speed, so that the bent sections of the radiating fins are longitudinally forced into the coupling flutes from the first to the second end of the main body to thereby tightly connect the radiating fins to the main body.

    Abstract: This invention relates to a method of manufacturing a heat exchanger block, to a spacer means for use in the method, and to a heat exchanger block. The heat exchanger block comprises a number of tubes and a number of fins, the fins having a predetermined spacing determined by the spacer means. The method includes the steps of locating the fins in a carrier and pressing the fins onto the tubes, and providing spacer means for the fins, whereby the spacer means supports a fin during the pressing step and determines the spacing between the fins in the assembled heat exchanger. Each of the fins has apertures for the tubes, the apertures engaging the tubes. Each of the spacer means has openings for the tubes, the openings being larger than the apertures.

  • Publication number: 20130228321
    Abstract: A heat exchanger, illustratively utilized in a fuel-fired pool heater, circumscribes a burner operative to discharge hot combustion gases outwardly through the heat exchanger. The heat exchanger has a tube portion helically coiled about an axis, with a series of heat transfer fins circumscribing the tube portion and spaced apart along it length. The fins on longitudinally adjacent pairs of coils of the tubing have nested facing edge portions which collectively form a seal area that coils between the tubing portion adjacent coil pairs in axially spaced relationships therewith, the seal area substantially impeding combustion gas flow therethrough in a direction generally transverse to the axis of the heat exchanger. Additionally, the fins have deformed laterally outer portions that define a coiled, circumferentially spaced series of restricted combustion gas outlets in substantial axial alignment with the helically coiled tube portion.

  • Patent number: 8418365
    Abstract: In a method for producing a heat exchanger tube bundle for a heat exchanger of an electrochemical energy accumulators, heat exchanger channels and an intended profile are incorporated into material strips by deep drawing. A forward-flow distribution aperture is incorporated into a first such material strip from step b) (first heat exchanger plate), and return collecting apertures are incorporated into a second such material strip, forming first and the second heat exchanger plates. The latter are aligned in such a manner that webs of the two heat exchanger plates border each other, and the heat exchanger channels form heat exchanger tubes. The heat exchanger plates arranged in this manner are joined together to form a heat exchanger tube bundle. A corresponding pressure welding apparatus, a heat exchanger tube bundle, a heat exchanger module, a heat exchanger with two or more heat exchanger modules, and an electrochemical energy accumulator with a heat exchanger of this type are also disclosed.

  • Patent number: 8375584
    Abstract: The present invention relates to a heat sink of a large area, in which a heat-dissipating body is further provided in its limited space. The method for manufacturing a fin includes the steps of providing a fin, cutting the fin to form a foldable piece thereon, folding back the foldable piece to be overlapped on the fin and form an accommodating hole, and punching the folded piece and the fin to form two overlapped through-holes. The fin, the heat-dissipating body and heat pipes are assembled together to obtain the heat sink. Since the fins and the heat-dissipating body dissipate the heat of the heat-generating element simultaneously, the heat-dissipating efficiency of the heat sink can be improved.
