    The cooling unit includes a blade-type cooling fins (17) attached to the projecting portion (13b) of a rotor shaft (13) projecting in to a cooling chamber (5) formed on the exterior of a motor case (10). A blower (25) for exhausting a cooling wind is mounted on the exterior of the cooling chamber (5) in the direction of the motor shaft flow-arranging fixed wings (29) with guide wings (29a) which are put radially in the exhausting space (28) between blade-type cooling fins (17) and the blower. In the cooling unit, in either case where the motor rotates normally or reversely, a spiral flow of the exhausted cooling wind passing through the blade-type cooling fins (17) is arranged to become a linear flow along the direction of the motor shaft through the flow-arranging fixed wings (29) and then exhausted out through the blower (25).

    专利说明:

    The invention relates to engine cooling devices, in particular (capable of rotating both in the forward direction and in the opposite direction, by which the cooling air could flow through the engine more efficiently.
    The aim of the invention is to increase the cooling efficiency.
    Figure 1 shows the proposed device, a longitudinal section; in fig. 2 is a section A-A in FIG. 1.
    The motor comprises a rotating shaft 1, a rotor 2 ,. mounted on the shaft, the stator 3, the barrel of the rotor j housing 4, in which the rotor and the stator are mounted, and which has a front 5 and rear 6 ends and several elongated holes 7 extending along the axis, and a cooling device including a cooling chamber 8 with an outlet 9 located coaxially in the housing at the rear end, axial cooling fins in the form of blades 10 and exhaust fan 11. The rotating shaft has a section 12 passing into the cooling chamber beyond the rear end capped blades 10. The specified fan is installed on the outside of the cooling chamber and the axial outlet opening in the axial direction.
    A radial shield 13 is attached to the axial ends of the cooling ribs. In the cavity of the cooling chamber, fixed axial spacing vanes 14 are installed, extending from the radial gap between the cooling ribs and the outer wall of the cooling chamber to the axial gap between the radial shield and the outlet opening of the chamber.
    The rotor shaft is mounted in bearings 15 and 16 fixed in the housing. In this case, the rotor has the ability to rotate in any direction. The front end of the rotor shaft, which serves as the output shaft of the engine, protrudes forward beyond the engine casing 9. Various external devices can be connected to this protruding end of the rotor shaft, which must be rotated (not shown). In front of the cooling fins, a cooling air guide wall 17 is provided, provided with cooling openings 18

    of air. The guide wall is placed in such a way that there is a small gap between it and the cooling ribs in the axial direction, and the gap between the wall 17 and the outer peripheral part of the rotor shaft should be sufficient to allow the cooling; (the flowing air, reflected from the inner surface cooling fins and rising radially. In this case, the cooling fins, sleeve 19, on which they are mounted, and the radial shield 13 can be made in the form of a single structure from a material that has good conductivity, for example, of aluminum. A ribbed casing 20 forming the outer wall for the cooling chamber can be attached to the body of a motor which is most appropriate for these purposes. The ribbed casing borders radially and axially in the radial and axial directions ribs.
    Outlet 9 is located directly opposite the cooling fins. The diameter of the hole roughly coincides with the diameter of the cooling fins. A fan is installed opposite the outlet 9. To cover the peripheral part of the exhaust fan, a cylindrical guide casing 21 is also attached to the ribbed casing. The latter is designed to direct the flow of cooling air, displaced by the exhaust fan, axially back side of the cooling device.
    As an exhaust fan, any fan can be used. The electrical circuit of the exhaust fan (not shown) is maintained independent of the electrical circuit of the engine (also not shown). Here, the exhaust fan rotates all the time in the same direction regardless of the direction of rotation of the engine. Even in the case when the cooling fins rotate at a low speed or do not rotate at all, the cooling air flows into the engine and is forced out of it by means of an exhaust fan, i.e. provides good engine cooling.

    In this case, the cross section of the space is divided in the radial direction with the help of aligning vanes. Due to this division of space, the cooling air is forced to flow already in the axial direction, rather than in a spiral manner. Thus, the vortex flow of cooling air created by the cooling fins, which rotate either in the forward direction or in the opposite direction, is almost completely rectified in axially, by means of the alignment vanes and fed to the exhaust fan. Due to this straightening of the flow of cooling air in the axial direction, the rotation of the exhaust fan is not disturbed under any conditions of the engine, i.e. regardless of whether the rotor shaft rotates in the forward direction. When this occurs, the effective displacement of cooling air from the engine.
