The cooling system of the internal combustion engine 1 includes a charge air cooler 2, a radiator 3 included in the coolant circuit, and a fan 4. The charge air cooler 2 is equipped with a fan 5 and is installed outside the radiator 3. The system may contain air intakes 6 and 7.

Description

The utility model relates to mechanical engineering and is intended for use in vehicles equipped with liquid-cooled internal combustion engines.

The closest set of essential features to the claimed technical solution is a cooling system of an internal combustion engine, comprising a radiator included in the coolant circuit and installed in front of it with at least partial overlap of its front, an air-to-air charge air cooler placed in their fan duct blowing (USSR AS No. 1250674, IPC F 01 P 3/20, Bull. No. 30, 08/15/86).

During the operation of this system, the entire frontal air flow first goes through the charge air cooler, then heated to the radiator, heating it, reducing the cooling efficiency, thereby increasing the heat load of the engine.

The proposed utility model solves the problem of increasing the cooling efficiency of the engine and charge air while increasing engine power without increasing the overall dimensions of the cooling system and engine compartment.

To achieve the specified technical result in a known cooling system of an internal combustion engine comprising a charge air cooler, a radiator included in the coolant circuit, and a fan, a charge air cooler is equipped with a fan and is installed outside the radiator installation, while the system may further comprise air intakes.

The applicant is not aware of the cooling system of an internal combustion engine with the specified set of essential features and the claimed set of essential features does not follow explicitly from the current level of technology, which confirms the compliance of the claimed technical solution with the condition of "novelty".

The proposed technical solution is illustrated by the drawings:

Fig. 8 is a side view of a cooling system of an internal combustion engine with side-mounted charge air coolers installed behind a cabin

The cooling system of the internal combustion engine 1 comprises a charge air cooler 2, a radiator 3 included in the coolant circuit, and a fan 4. The charge air cooler 2 is provided with a fan 5 and is installed outside the radiator 3. The system may contain two charge air coolers installed in front under the cabin (Figs. 5, 6), either sideways behind the cab (Figs. 1-4) or behind the cab (Figs. 7, 8), and Fig. 8 shows an option when charge air coolers 2 are installed behind cabin with one oh side. In the embodiment shown in figures 1-4, the system further comprises lateral air intakes 6, moreover, figure 1, 2 shows an option when the system is equipped with upper air intakes 7.

This arrangement of charge air coolers 2 allows air intake both from the front (stream A, goes to the radiator 3) and from the side and from above (stream B directed by the side air intakes 6 and stream C directed by the upper air intakes 7 go to the charge air coolers 2) .

This design of the cooling system of an internal combustion engine can significantly increase engine power without changing the size of the engine cooling radiator.

The inventive device provides improved cooling efficiency of the engine and charge air while increasing engine power without increasing the overall dimensions of the cooling system and engine compartment.

The cooling system of an internal combustion engine can be performed on standard equipment using modern materials and technologies.
