Abstract: A heat transfer device for a motor vehicle includes a rib/tube block arranged between two collection containers. The tube ends of the fin/tube block are widened in the area of each collection container and are then brought together flat into end packets. Both collection containers are set flush to a respective tube end packet and brazed hermetically to the same. At least one collection container is provided with at least one partition wall that divides the collection container. The partition wall has an outer contour that corresponds to the inner contour of the wall of the collection container. As a result, the partition wall can be soldered hermetically around the inner contour. A holding leg is provided on the partition wall and is inserted over two adjacent wall sections of neighboring tube ends of the tube end packet. One use of the device is as a water/air radiator.

Abstract: At least one flow control member (127a) is fitted in a fitting groove (133) formed in a tank (121). An insertion hole (204) is formed in at least a part of the fitting groove (133). The flow control member (127a) has a projection (205) to be inserted into the insertion hole (204). The projection (205) is smaller in size than the insertion hole (204). The flow control member (127a) is arranged at a predetermined position within the tank (121). The fitting groove (133) is defined by a pair of side wall portions (203b) formed by internally cutting a tank wall of the tank (121) in a thickness direction along a pair of parallel cutting lines, and a guide portion (203a) formed by extruding a portion of the tank wall between the side wall portions (203b). The insertion hole (204) penetrates the guide portion (203a). The projection (205) has first and second tapered portions (351, 352, 354, 355) so that the thickness and the width are reduced towards the top end.

Abstract: An automotive condenser (10) includes spaced manifold assemblies (18) comprised of semicylindrical tanks (20), matching semicylindrical headers (22) and simple, circular disks (38) serving as manifold separators. The disks (38) are sandwiched between the tank (20) and header (22) with no need for orientation, and with no slots or through notches to pierce the surface of the tank (20) or header (22). The disks (38) sit within matching pairs of common diameter grooves (30, 36) which provide complete, continuous pockets therefore.

Abstract: A tank part for a heat exchanger manifold of the type comprising separate tank a header parts joined to form a tubular manifold comprises an elongate channel-shaped member (18) and at least one partition member (6,8) fitted transversely therein, wherein the tank part is provided with inwardly protruding deformed regions on opposite sides of the or each partition to hold this in position, which comprise inwardly protruding dimples (24), and/or tabs (40,42) bent from portions upstanding from edge regions of the tank part.

Abstract: A heat exchanger comprises a first tank and a second tank spaced vertically from the first tank. The first tank includes a first partition disposed therein to divide the first tank into a first number of chambers, wherein the first number of chambers is at least two and has respectively an inlet to allow the heat transfer medium to enter the heat exchanger and an outlet to allow the heat transfer medium to exit the heat exchanger. The second tank includes a second partition disposed therein to divide the second tank into a second number of chambers, wherein the second number of chambers is preferably one less than the first number of chambers. The first tank and the second tank respectively include a concave surface horizontally formed on walls of the tanks, wherein one end of each of the first and second partitions respectively insert into each of the concave surfaces for preventing overturn of the partitions during assembly of the tanks.

Abstract: A condenser adapted for use in the car cooling system, the condenser comprising a pair of headers provided in parallel with each other; a plurality of tubular elements whose opposite ends are connected to the headers; fins provided in the air paths between one tube and the next; wherein each of the headers is made of a cylindrical pipe of aluminum; wherein each of the tubular elements is made of a flat hollow tube of aluminum by extrusion; and wherein the opposite ends of the tubular elements are inserted into slits produced in the headers so that they are liquid-tightly soldered therein. The questions raised in reexamination request No. 90/003,919, filed Aug. 7, 1995, have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e).This is a Reissue of a Patent which was the subject of a Reexamination Certificate No. B1 5,190,100, dated Aug. 30, 1994, Request No. 90/003,073, Jun. 3, 1993.
