摘要： A serpentine fin for assembly between tubes in a heat exchanger core, and a method of making same from a metal strip. The strip edges have a hem comprising a double thickness of the strip material extending inward from the edge. The metal strip has folds extending across the strip width such that the strip forms a serpentine shape, with the folds being adapted to contact the tubes in the heat exchanger core. Multiple rows of split louvers are disposed between adjacent folds. Each row of split louvers comprises louvers having openings extending in the direction of the strip length and formed in a pair of adjacent, spaced louver banks. Ribs are disposed parallel to the louver openings adjacent the strip edges and in at least one center portion of the strip between the strip edges, and extend across the pair of louver banks.

摘要： A method of manufacturing serpentine fins for assembly between tubes in a heat exchanger core. The method includes providing a flat metal strip and forming in the strip, multiple rows of split louvers. Each row of split louvers has louvers formed in pairs of adjacent, spaced louver banks extending across the width of the strip. Each row includes ribs formed in the strip parallel to the louver openings and extending across the pair of louver banks. The metal strip has unformed portions extending across the strip width between rows of split louvers for forming folds across the width of the strip. After forming the rows of split louvers, pressure is applied to the strip to cause the flat strip to buckle along the unformed portions forming folds in the strip resulting in the serpentine fin. Preferably, the strip has ribs formed both in the center portion and along the edges.

摘要： A low-cost, high-temperature heat exchanger is made from a notched piece of metal, the metal being folded back and forth upon itself to form a monolith. The notches in the metal piece create openings, communicating with distinct sides of the monolith. Ducts are attached to the openings. Cut pieces of corrugated metal, which may have a catalyst coating, are inserted between folds of the monolith. The heat exchanger may be used as part of a fuel cell system, or in other industrial applications, to recover waste heat, or to conduct various catalytic and non-catalytic reactions. The invention also includes an element, or building block, for a high-temperature heat exchanger, including a folded metal monolith with metal combs inserted, the monolith and the combs defining seams which are hermetically sealed.

摘要： A method for riveting fins into a bottom plate of a heat dissipating device is disclosed. A punching device has a plurality of weights each of which is formed as a thin sheet. The punching device is installed to a fixture; a plurality of fins are spaced with a predetermined gap; and a bottom plate is formed with a plurality of trenches for receiving the fins. The method comprising the step of: positioning the bottom plate at the fixture; inserting the fins into the trenches of the bottom plate; inserting the weights of the punching device into the fins so that each space between two fins has a weight; and punching a backside of the bottom plate by a puncher so that as the bottom plate moves; the weights collides portions of the bottom plate between the fins to deform and rivet the fins into the bottom plate; and thus the fins are firmly secured in the bottom plate.

摘要： A heat exchanger comprising at least one row of flattened tubes through which a heat exchange medium may pass. A serpentine fin 10 disposed between adjacent flattened tubes has relatively straight segments that are connected by bend radii 20. The fin 50 defines a plurality of louvers 32 therein. Each louver 32 forms an elongated slit that extends at least partially into the bend radii 20, through which a fluid to be heated or cooled by the medium may pass. The fin 50 is formed by a tool with fin blades that have tips that are configured to form the extended length louver that protracts into the bend radius that separates adjacent convolutions.

摘要： A method for forming heat exchanger plates comprises formation of a fluid flow channel along the edges of a sheet metal strip or blank, and formation of a pair of raised end bosses. The raised end bosses are elongated in the longitudinal dimension and are formed within the final width dimension of the plate so as to avoid the need for trimming of excess material along the edges of the plate. The method generates less scrap than prior art processes using progressive stamping, and also permits variation of the plate lengths.

摘要： A one-piece extrusion (50) having a flat bottom portion (54) and supporting flat sides (74) is described. The one-piece extrusion (50) is particularly appropriate for use as a header for a heat exchanger in a cogeneration facility or other high pressure vessels. The header (50) is extruded out of steel, stainless steel, or a steel alloy. The flat bottom portion (54) of the header (50) provides a flat surface for drilling apertures (80) and connecting tubes (56) to the header (50), eliminating the need for complicated manufacturing and attachment procedures encountered with the cylindrical headers currently used. The flat bottom portion (54) also provides more surface area for attachment of the tubes (56). The flat sides (74) of the extrusion impart structural support and integrity to the header (50) and allow a greater number of headers to be placed closer together without taking up the space required for typical cylindrical headers.

摘要： A method for making a heat dissipation device (3) includes the steps of: providing a metal plate (2) and a fin member (1), bending the metal plate to form a body (2′), and attaching the fin member to the body. The metal plate includes a central portion (22) and a pair of end portions (24). The central portion is thicker than the end portions. The body includes a chassis (22′) originating from the central portion of the metal plate, and a pair of side walls (24′) originating from the end portions of the metal plate. The fin member is attached to the chassis between the side walls.
