Description

one

The invention relates to the field of mechanical engineering, in particular to engine-building and, in particular, to the implementation of radiators of the cooling system of internal combustion engines .5

Radiators of the cooling system of internal combustion engines are known, comprising an upper and a lower tank, a tubular core located between them, a vapor-air valve and a baffle with channels, installed in the upper tank and dividing it into interconnected collector and expansion chambers, the collector chamber communicated by the core tubes with the lower 15 cistern 1.

The expansion chamber removes air and vapor from the coolant. However, this is partially removed from the system through the vapor-air valve 20 and liquid.

The aim of the invention is to increase the efficiency of the radiator by preventing the release of coolant.25

In order to achieve this goal, the expansion chamber is provided with a dividing partition, made with a drainage hole and forming a separation cavity and a cavity in communication with the vapor-air valve.

The partition can be installed vertically.

The drainage hole can be placed on the wall, occupied by fluid in the separation cavity during expansion.

FIG. 1 schematically shows the proposed radiator; in fig. 2 - the same, side view.

The radiator of the internal combustion engine contains the upper 1 and lower 2 tanks, which are connected by a core 3, made in the form of tubes 4.

In the upper tank I, a partition 5 with channels 6 is installed, dividing it into a collector chamber 7 and an expansion chamber 8 communicated with each other, the collector chamber 7 being connected by tubes 4 of core 3 to the lower tank 2.

In the expansion chamber 8 there is a dividing partition 9 with a drainage hole 10, forming a separation cavity 11 and a cavity in communication with the vapor-air valve 12.

The drain hole 10 may be located at the level occupied by the liquid in the separation cavity during expansion.

The radiator works as follows.

When the engine is not running, the ldd level in the radiator is set somewhat higher than the partition 5 with the formation of air space in the scrub chamber 8.

In operation, the cooled liquid enters the collector chamber 7 under the partition 5, passes through the tubes 4 of the core 3 into the lower tank 2 and then leads to the engine. Air and coolant flows come from the collector chamber 7 through the channels 6 into the separation cavity I, where high pressure is created.

From the separating floor 11, air and vapors exit through the drainage hole 10 into the air space of the expansion chamber 8 behind the additional partition 9, from where it is diverted through the steam-air valve 12.

With a sharp increase in pressure and temperature of the coolant, the level of the liquid in the separation cavity 11 rises and the liquid through the drainage hole 10 is discharged into the expansion chamber 8, where through a series of tubes 4 enters the lower tank 2. This ensures a constant level of liquid in the expansion chamber 8 behind the partition 9.

The implementation in the expansion chamber 8 of the separation cavity I, in which air and steam are separated from the coolant, eliminates the release of fluid along with steam and air from the radiator, ensuring a constant fluid level during long-term operation and thereby reducing the maintenance of the cooling system. generally.
