Abstract: This invention relates to apparatus for facilitating the construction of a heat exchanger, such as a condenser or evaporator employed in an air conditioning system, wherein exchanger tubes extending through a plate fin assembly are joined together by means of return bend connections or the like. The ends of the tube are provided with an oval shaped bell in which are telescoped the return bends. Diametrically opposed nibs are formed on the outer surface of the return bend connectors near the distal end thereof. The outside diameter over the nibs is slightly larger than the minor inside diameter of the oval bell. The nibs are inserted into the bell aligned along the minor diameter of the opening. The nibs are thus caused to ride in engagement against the wall of the bell to frictionally support the connector in assembly. The joint is then immersed in a molten solder bath whereby solder flows freely into the joint region along the major axis to create a highly reliable joint.

Abstract: A heat exchanger for an air conditioner comprises a plurality of heat-transfer tubes arranged in parallel to each other at predetermined intervals, and heat-transfer fins formed by helically winding a plurality of fine wires around the plurality of heat-transfer tubes. 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: An improved method is provided for producing an aluminum tube of the type used as cooling tubes for heat exchangers, and particularly automotive heat exchangers. The method utilizes a flux-containing composition that can be selectively deposited in a manner that permits the manufacture of aluminum tubes having a lockseam construction. As a result, the method made possible by this invention provides for the manufacture of heat exchanger tubes that offer the weight, durability and safety advantages of aluminum alloy construction, but at lower investment, processing and material costs as compared to prior art welded aluminum tubes. Another advantage of the present method is that minimal amounts of braze alloy and flux are required, yet uniform and consistent brazed joints can be produced to yield leak-proof brazed assemblies.

Abstract: In a method of manufacturing a plate heat exchanger individual plates are connected to pairs such that the individual plates are parallel to and spaced from one another by edge portions with a common edge. The pairs are combined to a plate stack such that the common edges are parallel. A sealing strip, having a slotted end face with parallel slots, is positioned at the end of the plate stack such that the common edges are received in the slots and the edge portions abut the slotted end face and such that the end of the plate stack projects slightly past the outer surface of the sealing strip perpendicular to the slotted end face. The sealing strip is welded to the common edges by using at least a portion of the material of the plate stack end projecting past the outer surface. The edge portions are welded to the outer surface of the sealing strip by using exclusively the material of the plate stack projecting past the outer surface. The welding heat is continuously dissipated by placing a shaped part, made of a material having good heat-conducting properties, onto the surface of the sealing strip opposite the outer surface.

Abstract: A laminate type heat exchanger is formed from a plurality of plates and integrally brazed and joined. This heat exchanger includes a joint block, a refrigerant heat-exchanging portion which causes heat exchange between refrigerants, and an evaporating portion which causes heat exchange between refrigerant and passenger-compartment air. The inventors formulated new index to perform successful integral brazing. A reference volume of a portion is a volume of the portion providing a predetermined amount of heat-receiving surface area of the portion,an index A of the portion is defined byA=(volume of material of the portion to be heated existing in a reference volume of the portion)/(the reference volume of the portion), and a ratio of an index A1 which is the index A of the first portion and an index A2 which is the index A of the second portion, i.e., A1/A2 is set within a certain range. Preferably, the certain range of the ratio of A1/A2 is defined by 1/2.2.ltoreq.A1/A2.ltoreq.2.2. Plate thickness t1 of plates forming the refrigerant heat-exchanging portion and plate thickness t2 of plates of the evaporating portion have a relationship that a ratio t1/t2 is set within a range of 0.17.ltoreq.t1/t2.ltoreq.0.75.
