This invention relates to a radiator of a car engine cooling system.

The purpose of the invention is to increase the compactness.

Figure 1 shows the core of the radiator; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2.

The radiator contains channels 1 and 2 formed by metal sheets 3.4, some of which have bent sections 5, with sheets 3.4 on part of the edges having taps 6, 7. One sheet 3 is made zigzag with vertical and horizontal sections 8, 9, forming with bent sections 5 of the remaining sheets 4 bottoms of 10 collectors 10 (not shown), and in the odd joints of the vertical and horizontal sections 8, 9 of the zigzag sheet 3 are made slots 11, and the remaining sheets 4 are provided with corrugations 12, the ends of which are aligned with these slots 12 Select 6 rtovki zigzag sheet 3 are formed on the edges of its vertical portions 8, while the other sheets 4 otbortov- ki 7 formed at the edges of the bent portions 5.

The radiator is assembled as follows.

Corrugated sheets 4 are installed in the zigzags of the sheet 3, thus forming the channels 1, 2 for the passage of working media and the bottom 10 of the collectors. The collected sheets 3, 4 are fixed by rolling the flanging 6, 7, after which the collectors are fixed on the bottoms 10 by rolling the flanging

6, 7 around the perimeter of the bottoms 10, and the assembled radiator is placed in a brazing furnace.

The radiator works as follows.

The cooling fluid of the car's motor circulates in a closed circuit and is cooled in the channels 2 of the radiator formed between the vertical walls 8 of sheet 3 and the corrugations of 12 sheets 4, due to

heat release to air blown through the channels 1.

The invention allows to simplify the manufacturing technology and increase the compactness of the radiator.

Claims (2)

1. A radiator containing channels formed by metal sheets, some of which have bent sections under the bottoms of water collectors, and the sheets on the part of the edges have flanges, characterized in that, in order to increase the compactness, one sheet is made zigzag with vertical and horizontal sections forming with bent sections the remaining sheets of the bottom of the collectors, and in the odd joints of the vertical and horizontal sections of the zigzag sheet, cuts are made, and the remaining sheets are provided with corrugations, the ends of which are aligned with these cuts. 2. The radiator according to claim 1, characterized in that the flanging of the zigzag sheet is made on the edges of its vertical sections, and the remaining flanging sheets performed on the edges of their bent sections.
