The radiator contains a package of U-shaped finned tubes 1, fixed in the support plate 2, and inlet 7 and outlet 8 collectors, which are integral with the support plate and provided with channels into which the ends of the 6 tubes 1 are inserted. Each tube 1 is flat-oval, the flat side of which placed perpendicular to the frontal surface of the radiator, and the bends of the U-shaped tubes 1 are oriented parallel to the frontal surface of the radiator. The finning of each tube is made integral with it along its flat sides, which increases the efficiency of heat dissipation. 2 hp f-ly, 3 ill.

Description

This invention relates to mechanical engineering, namely k engine cooling systems for an internal combustion engine, and concerns liquid-air heat exchangers.

The purpose of the invention is to increase the efficiency of heat scattering.

FIG. 1 shows a radiator, transverse cut; in fig. 2 - the same, longitudinal section; in fig. 3 shows an embodiment of a radiator, a transverse section.

The radiator, made in the first embodiment, contains a package of U-shaped flat-oval silvered tubes 1 fixed in the support plate 2, the bends of 3 tubes 1 are oriented parallel to the frontal surface of the radiator, and the flat sides 4 of tubes 1 are placed in planes perpendicular to the front surface of the radio gate . All the bends of the U-shaped tubes 1 along the depth of the radiator are located in one row, and their axes of symmetry are located in the frontal plane. Channels 5, into which the ends of 6 tubes 1 are connected, are in communication with the inlet and outlet headers 7 and 8, and the support plate 2 is made at the same time with them. The fin 9 of each tube is made together with it on its flat sides 4. The ends 6 of the tubes 1 in the manifolds 7 and 8 are fixed with the help of a common for all tubes of the rubber plate 10. The inlet and outlet headers 7 and 8 are connected to the inlet pipe. and the outlet channels 11 and 12 are made using a common clip 13 with spacers 14 being placed between them. The ribs on the flat sides of the tubes are made by the planing method, which makes it possible to obtain a sufficiently high coefficient of tube finning without any loss of metal of the tubes. In the proposed design, the axis of the input and output collectors 7 and 8 can be located relative to each other at an angle from 0 to 180.

The radiator of the cooling system of the internal combustion engine works as follows.

Coolant from the engine is fed into the radiator through the inlet manifold 7, from which it passes

It enters the channels 5. From the channels 5, the cooling fluid through the ends 6 of the tubes 1 is directed into the tubes 1, passes through the bends of 3 tubes 1 into the adjacent channels 5, and of them returns to the engine via the output manifold 8. When the coolant moves through the tubes 1, it is cooled by directing the flow of air between the tubes and their finning.

The arrangement of the elements of the U-shaped radiator tubes provides increased heat transfer to the air, and the implementation of the ribs along with the walls of the U-shaped tubes virtually eliminates thermal resistance between the walls of the tubes and the fins, which significantly reduces the depth of the radiator.
