    摘要: The invention relates to a heat exchange core, for example for cooling fluid coolers or charge air coolers, comprising flat tubes (1) have two narrow and two wide sides (10, 20) and having inner channels (30) and intermediate spaces (3) remaining between the wide sides (20) of adjacent flat tubes (1), at least some of the successive flat tubes (1) being subject to parallel fluid flow through them, the other medium flowing approximately transversely thereto through the intermediate spaces (3), and the two wide sides (20) of the flat tubes (1) having deformations in the form of waves (15), characterized in that the flat tubes (1) can be produced from at least one endless formed sheet metal strip (a), wherein the inner channels (30) are formed by another wave-shaped formed sheet metal strip (c) or a wave-shaped formed strip segment of the one sheet metal strip (a), the wave peaks and wave troughs thereof being metal bonded to the inner wide sides (20) of the flat tubes. The invention chiefly leads to cost reductions.

    摘要: A heat exchanger comprises: a pair of headers (10, 10) which are provided in parallel facing each other through a predetermined distance and a pathway of the fluid is respectively provided therein; and a plurality of flat heat-exchange tubes (20,20...) which are provided between the headers in parallel, both ends thereof are fastened to the headers, and a pathway of the refrigerant for connecting the pathways of both headers is respectively provided therein. In this heat exchanger, the heat-exchange tubes and the headers are air-tightly and liquid-tightly fastened by inserting end portions (21,21...) of the heat-exchange tubes into insertion holes (11,11...) which are bored on the headers. Furthermore, in the vicinity of opening ends (29) of both end portions of the flat heat-exchange tubes, shape-holding portions (41) for preventing deformation of the opening ends are provided.

    摘要: Die Erfindung betrifft einen Wärmeübertrager mit einer Mehrzahl von zumindest in einer Reihe angeordneten und parallel zueinander von einem der am Wärmeaustausch teilnehmenden Medien durchströmten Rohren (R), die einen flachen Rohrquerschnitt mit im Verhältnis zur Breite geringer Höhe aufweisen und auf ihren gegenüberliegenden Flachseiten mit die Wärmeübertragungsfläche vergrößernden Rippen (F) versehen sind. Um derartige Wärmeübertrager preiswert herzustellen und mit Rippenrohren bestücken zu können, die einen verbesserten Wärmeübergang ergeben, sind die Rohre (R) mit ihren Flachseiten parallel zueinander liegend und mit ihren Rippen (F) einander berührend zu einem mindestens eine Rohrreihe umfassenden Element zusammengefaßt und zwischen einer Kopfplatte (P k ) und einer Fußplatte (P f ) angeordnet, die miteinander durch Zuganker (X) verbunden sind.

    摘要: A refrigerant tube (T1) for use in heat exchangers comprises a flat aluminum tube (5) having parallel refrigerant passages (4) in its interior and comprising flat upper and lower walls (1,2) and a plurality of reinforcing walls (3) connected between the upper and lower walls (1,2), extending longitudinally of the tube (5) and spaced apart from one another by a predetermined distance. The reinforcing walls (3) are each formed with communication holes (6) for causing the parallel refrigerant passages (4) to communicate with one anther therethrough. The flat aluminum tube (5) is prepared from upper and lower two aluminum sheets by bending opposite side edges of the lower aluminum sheet to a raised form and joining the bent edges to the respective side edges of the upper aluminum sheet which is flat so as to form a hollow portion. The reinforcing walls (3) are formed by joining to the inner surface of the upper wall ridges projecting inward from the lower wall. The communication holes (4) are formed by cutouts formed in the edges of the ridges at a predetermined spacing and having their openings closed with the upper wall.
