The invention relates to a box for receiving a coolant for a heat exchanger (1) used for motor vehicles. Said box comprises two sidewalls (22, 24 and 22a, 24a), two end walls (26, 28 and 26a, 28a), a cover (18 and 18a), and a bottom (20 and 20a) which is located opposite the cover (18 and 18a) and is provided with one or several openings (60) for receiving tubes, particularly connecting tubes, such as flat tubes. The cover (18 and 18a) is provided with at least one recess (90, 92, 94) into which reaches at least one extending wall (26, 26a, 28, 28a, 32).
摘要:
The invention relates to an arrangement for fixing a first heat exchanger (2) to a second heat exchanger (3), the first heat exchanger (2) comprising a first block (9) provided with tubes (16), ribs, and lateral parts (10, 21) arranged parallel to the tubes (16), in addition to collecting tanks (13, 14) arranged on both sides of the first block (9), transversally to the tubes (16), especially consisting of a castable or injectable material. The second heat exchanger (3) comprises a second block (4) provided with tubes (17), ribs, and lateral parts (8, 22) arranged parallel to the tubes (17), in addition to headers (5, 6) which are arranged on both sides of the second block (4), transversally to the tubes (17). The tubes (16) of the first block (9) and the tubes (17) of the second block (4) are arranged parallel to each other. According to the invention, the two heat exchangers (2, 3) are interconnected between the lateral parts (10, 8) thereof and/or between at least one lateral part (21) and the headers (5, 6), by soldered connections (15a, 15b, 15c, 15d).
摘要:
The invention relates to a casing for holding a coolant for a heat exchanger (1) for motor vehicles, said casing having two side walls (22, 24 and 22a, 24a), two front walls (26, 28 and 26a, 28a), a cover (18 and 18a) and a base (20 and 20a) lying opposite the cover (18 and 18a), said base being provided with one or more openings (60) for receiving tubes, in particular connecting tubes such as flat tubes. According to the invention, the base (20 and 20a) and at least one of the two side walls (26, 28 and 26a, 28a) consist of a one-piece shaped part, produced in a forming method.
摘要:
The invention relates to a metal side plate for a radiator, in particular a tubular radiator, such as those found in motor vehicles with combustion engines. According to the invention, the metal side-plate (20) is secured to securing points (13) on both sides on the collecting tubes (12) and a longitudinal slot (21) is introduced into the metal side-plate on at least one side in the region of the fixing. The fixing points (13) on the metal side plates (20) are embodied on collecting tubes (12) on one side of the longitudinal slot.
摘要:
The invention relates to a heat exchanger unit for motor vehicles, comprising one first heat exchanger (10) and one second heat exchanger (12). Each heat exchanger (10, 12) comprises two collector pipes (14, 16 and/or 18, 20) which are arranged at a distance from each other. One collector pipe (14) of the first heat exchanger (10) is arranged substantially adjacent to one collector pipe (18) of the second heat exchanger (12). Also, the other collector pipe (16) of the first heat exchanger (10) is arranged substantially adjacent to the other collector pipe (20) of the second heat exchanger (12). One and/or the transversal sections (48, 52) of the covering wall (50, 54) of said collector pipe (14, 16) does not have a circular shape, said sections being perpendicular to the longitudinal axis (32, 34) of a collector pipe of the first heat exchanger (12),
摘要:
The invention relates to a heat exchanger, in particular, for a heat exchanger unit comprising at least one finned tube block and condenser collectors or refrigerant chambers provided for the ends of the tubes of the finned tube block, whereby at least one finned tube block has an essentially curved embodiment in the longitudinal direction of the tubes, in other words, in the direction of the tubes between the collector chambers.
