    Motor-fan unit, particularly for the cooling of the circulation water of an automobile vehicle motor, comprising a helicoid fan driven by an electric motor. A centrifugal interior blading draws in the air through the electric motor to cool it and drives this air back into a volute surrounding the axis of the motor-fan unit. The volute opens at the same side as the electric motor in relation to the vanes of the helicoid fan. An electrical resistor, usable for making the motor-fan unit turn at reduced speed, can be placed in the volute or at the outlet of the volute to be cooled by the air stream.

    (54) DEVICE FOR A FORCED AIR SUPPLY TO RADIATOR BLOWNING The invention relates to mechanical engineering, in particular to engine building and, in particular, to devices for cooling individual parts of an engine. Devices are known for forcing air to blow the radiator of an internal-combustion engine cooling system, containing an annular shell disposed inside and coaxial with it, an axial-flow fan driven by an electric motor fitted with a housing which coaxially with it, and a system of centrifugal blades located inside the casing . The water cooling system fan can be placed either in front of the radiator to blow air through it, or behind the radiator to draw air through it, with the electric motor in the first case often located on the suction side of the fan, and in the second case from the dipping side J1 . However, the cooling efficiency of the electric motor placed in the known devices for forced ventilation, both on the discharge side and on the suction side of the screw fan, is insufficient. The purpose of the invention is to increase the cooling efficiency of an electric motor. To achieve this goal, the device further comprises a cochlea located between the fan and the electric motor and provided with an outlet in the area of the fan. FIG. 1 schematically shows a device for forcing air supply for radiator airflow in a variant, when a fan draws air through a radiator, a longitudinal section; in fig. 2 is a view A of FIG. one; in fig. E - device for forced air supply for radiator airflow in the variant when the fan blows air through the radiator, longitudinal section; in fig. 4 - device for forced air supply for radiator airflow, longitudinal section; in fig. 5 - view B (the rotor is shown in partial section). The device for forcing air to blow in the radiator 1 of the engine cooling system of the internal combustion engine contains an axial
    fan 2 driven by an electric motor 3 placed inside the annular shell 4 and coaxial with it, a system of centrifugal vanes 5 placed inside the casing b of the electric motor 3, and the cochlea 7 placed between the fan 2 and the electric motor 3 on the front part of the casing 6. Snail 7 is provided with an outlet 8 in the region of the fan 2. In the casing 6, holes 9 are made 9. The casing 6 of the electric motor 3 is connected to the annular shell 4 by means of the lugs 10.
    Arrows B show the direction of the air flow.
    The operation of the device in the embodiment shown in FIG. 1 is carried out as follows.
    When the engine is operating, through the openings 9, the air flow B, moving towards the front of the electric motor 3, penetrates into the casing 6 of the electric motor 3, cools it and is sucked in by centrifugal blades 5 that force it into the cochlea 7, where it slows down and leaves through the openings 9 under pressure significantly higher than the pressure of the main air flow B. Thus, the pressure of the air flow B cannot prevent it from leaving the holes
    When the device is executed in the embodiment shown in FIG. 3, the air flow passing through the openings 9 of the casing b and the outlet opening 8 is captured by the blades of the fan 2 and blown together
    with a flow in through the radiator 1, and re-passing the flow through the casing 6 of the electric motor and the cochlea 7 is excluded.
    Thus, the organization of additional air flow through the centrifugal vanes 5 of the cochlea 7, in addition to the main air flow B created by the fan 2, contributes to a better cooling of the electric motor.
