Benefits of technology

[0007] According to one aspect of the present invention, a heat exchanger includes at least one collecting tank and at least one row of flat tubes. The flat tubes have a first end secured to the collecting tank to discharge therein, a closed second end, and at least one longitudinal separator in the tubes dividing the tubes into oppositely-traversed channels, wherein at least a portion of one tube wall at the c

Problems solved by technology

Both the rod to be inserted and the part of the bead to be flattened are obstacles to a cost-effective manufacturing process.

Embodiment Construction

[0029] The Figures illustrate different variants of air-cooled coolant radiators which may be advantageously produced completely from aluminum. The coolant, according to the arrows C (see, e.g., FIG. 1, flows through flat tubes 10. Cooling air flows across the flat tubes 10 through heat exchanger elements (corrugated ribs) 12 between and in heat-conducting connection with the flat tubes 10 (the corrugated ribs 12 are not shown in FIG. 1 but are indicated in FIG. 4) as indicated by arrow A in FIG. 1.

[0030] The heat exchanger according to FIG. 1 includes a collecting tank 20 with a partition 22 (indicated by a dashed line) separating the collecting tank 20 into an inlet side 24 and an outlet side 26. A collecting tank inlet 30 is on the inlet side 24 and a collecting tank outlet 32 is on the outlet side 26.

[0031] It should be appreciated that it would be within the scope of the present invention for there to be, for example, two directly adjacent or connected collecting tanks (with,...

Abstract

A heat exchanger including a collecting tank and at least one flat tube row. The flat tubes have a discharge end secured to the collecting tank, a closed end, and a longitudinal separator dividing the tubes into oppositely-traversed channels, wherein at least a portion of one tube wall at the closed end and the separator associated with the tube wall portion are omitted. A closure piece closes the tubes where the tube wall portions are omitted. A partition in the collecting tank separates the inlet and outlet sides. Heat exchanger elements between the flat tubes are adapted to be traversed by a medium flowing outside the tubes. The first tube row may be connected with one end to one side of the collecting tank with a second tube row connected with its first end to another side of collecting tank.

Description

CROSS REFERENCE TO RELATED APPLICATION(S) [0001] Not applicable. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable. REFERENCE TO A MICROFICHE APPENDIX [0003] Not applicable. TECHNICAL FIELD [0004] The present invention is directed toward heat exchangers, and more particularly to vehicle coolant radiators. BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS POSED BY THE PRIOR ART [0005] A radiator for the cooling unit of an internal combustion engine of a vehicle is shown and described in DE 34 40 489 C2, and has a collecting tank divided into parts by a partition, with a series of flat tubes discharging on one end into the tank. The flat tubes are divided into oppositely traversed channels by a longitudinal separator, which terminates short of the other tube end, whereby there is flow connection between the channels in the other end of the flat tubes. Accordingly, it will be appreciated that flowing medium in one part of the collecting tank enters ...
