Description

The utility model relates to a cooling system of machines or engines and, in particular, to the design of radiators with a system for deaerating the coolant.

A known radiator with a coolant deaeration system, including the upper and lower tanks, connected by tubes, the upper tank consists of a receiving chamber with an inlet pipe, a collector and air removal chambers communicating with each other, the air removal chamber has a steam-air valve, the collector chamber is in communication with the lower tank, having an outlet pipe (see patent for invention No. 2187664 IPC7 F 01 P 11/02).

Such a design does not provide sufficiently effective removal of air from the coolant during engine overload conditions.

The closest to the proposed utility model in terms of essential features (prototype) is a radiator with a two-stage deaeration system for coolant, including the upper and lower tanks connected by tubes, the upper tank consists of two independent parts: from the lower part, which is a collector chamber, and from the upper part with a built-in coolant deaeration system, consisting of the intake and exhaust chambers, which are separated by a partition, the intake and exhaust chambers together are interconnected through a vertically located tube fixed to the partition, the collector chamber is divided by a vertical partition into larger and smaller parts, the collector chamber communicates with the receiving and air-removing chambers (see utility model patent No. 40079 MPK7 F 01 P 11/02).

However, this design ensures the operation of the engine cooling system only at low coolant speeds (up to 1 m / s), and at higher speeds, operating efficiency is significantly reduced.

The proposed utility model solves the problem of ensuring the effective operation of the engine cooling system with a high capacity water pump.

This is achieved by the fact that in the known radiator with a two-stage deaeration system of the coolant, including the upper and lower tanks connected by tubes, the upper tank consists of two independent parts: from the lower part, which is a collector chamber, and from the upper part with an integrated cooling deaeration system liquid, consisting of a receiving and air-removing chambers that are separated by a partition, a receiving and air-removing chambers communicate with each other through a vertically located tube fixed on the partition, the collector chamber is divided by a vertical partition into larger and smaller parts, the collector chamber communicates with the intake and exhaust chambers, the new one is that the free end of the tube through which the intake and exhaust chambers communicate is rolled up and has only a small hole, the upper part of the tube, through which the collector and air extraction chambers communicate, it is located in a sealed tube.

The upper part of the tank with an integrated deaeration system has at least two sealed tubes through which the intake and exhaust chambers communicate.

The upper part of the tank with an integrated deaeration system has at least two tubes through which collector and air extraction chambers located in the rolled tubes communicate.

The proposed design of a radiator with a two-stage system of deaeration of a cooling liquid solves the problem of quick and effective removal of air from a cooling liquid in cooling systems

energy-saturated engines with high performance water pump, i.e. at high coolant speeds.

Figure 1 shows a General view of the radiator with a two-stage system for deaeration of the coolant.

A radiator with a two-stage deaeration system contains the upper 1 and lower 2 tanks, which are connected by tubes 3.

The upper tank 1 consists of two independent parts: the lower collector chamber 4 and the upper 5 with a built-in deaeration system. The upper part 5 of the tank 1 with an integrated deaeration system consists of a receiving chamber 6 and an air-removing chamber 7, which are separated by a partition 8. The partition 8 has a trough-like shape.

The collector chamber 4 has a vertical partition 9 dividing the chamber into large 10 and smaller 11 parts. The smaller part 11 of the collector chamber 4 communicates through the compensation tube 12 with the air extraction chamber 7. The majority 10 of the collector chamber 4 communicates through the tube 13 with the intake chamber 6 and two tubes 14 communicate with the air extraction chamber 7.

The intake chamber 6 has two inlet pipes 15. The air exhaust chamber 7 has a steam-air valve 16. Two tubes 17 are vertically soldered on the partition 8 separating the intake 6 and the air exhaust 7 chambers of the upper part 5 of the tank 1. The free end of the tubes 17 is sealed and has only a small hole 18. The diameter of the rolled tubes 17 is larger than the diameter of the tubes 14,

Initially, the coolant is poured into the engine cooling system through the filler neck 19 of the radiator and through the compensation pipe 12 enters the smaller part 11 of the collector chamber 4, then through the tubes 3 it enters the lower tank 2 and is directed to the engine through the exhaust pipe 20.

The radiator works as follows. When the engine is running, hot coolant from the engine through the nozzles 15 enters

the receiving chamber 6 of the upper part 5 of the tank 1, part of the air in the liquid rises through the rolled tubes 17 from the receiving chamber 6 into the air-removing chamber 7. In the upper rolled part of the tubes 17 due to the intensive air outlet, an ejection effect is created. Further, the liquid from the intake chamber 6 through the tube 13 enters the greater part 10 of the collector chamber 4. The remaining air from the collector chamber 4, under the influence of vacuum, is forced to be sucked out through the tubes 14. The air entering the air removal chamber 7, together with the vapors, through the steam-air valve 16, goes into the atmosphere. The deaerated liquid from the greater part 10 of the collector chamber 4 through the tubes 3 enters the lower tank 2 and through the outlet pipe 20 is directed to the engine.
