Abstract: A method of manufacturing flat tubes by forming a flat tube body from a single plate material which is continuously drawn from a drum by either folding it into two or placing two plate materials one upon the other, and cutting the flat tube body in a predetermined length. The method is characterized by the steps of placing the plate material with its inner surface facing downwardly at any selected stage before completion of folding the plate into two, or before completion of placing two plates one upon the other; fluxing the inner surface of the plate material with a liquid flux material, and drying the applied flux material.

Abstract: A tube/fin block for a heat exchanger has several tubes through which a heat transfer fluid can flow arranged side-by-side along a transverse direction of the block. Corrugated-fin complexes are inserted between respective adjacent tubes and are connected with the adjacent tubes. At least one of the corrugated fin-complexes is a double corrugated-fin complex with two corrugated-fin units arranged side-by-side in the transverse direction of the block. A particular manufacturing process for the tube/fin block is utilized. A heat insulation device is provided between the two corrugated fin units. A non-solderable spacer plate can be inserted between the two corrugated fin units and pulled out after the tube/fin block is soldered together so that a heat-insulating gap is formed. A plastic strip can be inserted into the heat-insulating gap as required. The block is appropriate for use, for example, in condensers and evaporators of motor vehicle air conditioners.

Preferably, the heat-transfer tubes are divided into groups of two adjacent heat-transfer tubes (1a, 1b), (1b, 1c), (1c, 1d), . . . , and at least one fine wire fin is wound helically around the two adjacent heat-transfer tubes of each group so that the fine wire fin does not cross other portions of the fine wire fin as viewed along a direction perpendicular to a plane including the axes of the plurality of heat-transfer tubes. When fabricating the heat exchanger, at least either the outer circumferences of the heat-transfer tubes or the outer circumferences of the fine wires are coated with a metal film formed by plating, and then the heat-transfer tubes and the fine wires are interlaced to form a heat exchanging structure. Then, the heat exchanging structure is heated to the melting point of the metal film so that the metal film is melted and the heat-transfer tubes and the fine wires are bonded together by the molten metal film.

Abstract: The invention relates to a method for brazing flat tubes of a laminated heat exchanger comprising laminating a plurality of flat tubes (2) which have a brazing material claded with a fin (3) therebetween, inserting both ends or at least one end of each flat tube into tube insertion ports (5) of header tanks (4), and integrally brazing the ends of the flat tubes and the tube insertion ports, wherein the tube insertion ports have a width (A) larger than that (B) of the flat tubes, the laminated heat exchanger is transversely placed to vertically position the width direction of the flat tubes when integrally brazing after assembling, and a jig (19) is used to support so as to form a gap (20) at the lower parts of the flat tubes and the tube insertion ports before effecting brazing. Thus, the flat tubes can be firmly inserted when assembling, a brazing property between the tube insertion ports and the flat tubes can be improved, and beads can be mutually brazed with reliability. As a result, a laminated heat exchanger having a pressure resistance can be acquired.
