  • Patent number: 7167364
    Abstract: A cooler for cooling of electronic components comprises at least two heatsinks thermally connected with each other by heat spreading means, and a double inlet centrifugal blower comprises a casing with two inlets and an outlet, a radial impeller with an axle and an electric drive. The cooler thermally connected with the electronic component. Each of the heatsinks comprises inflow and outflow openings, and thermally connected heat exchanging means and a base. The impeller comprises radial blades located from both sides of an impeller disk. The double inlet centrifugal blower is located between the heatsinks thus each of the outflow openings is coincided with the closest inlet, so cooling air flows through the inflow openings, the heat exchanging means, the outflow openings and the inlets of the blower in a series way.

  • Patent number: 6998751
    Abstract: An electric drive comprising a stator with at least two ring-shaped windings and controllers, and a magnetized rotor with an axis of rotation. Each of said windings comprises at least one coil layer with circumferentially arrayed coils located around said axis, and a layer of electro-insulating material, and each winding is electrically connected to a power source through an individual controller. At least two said windings are electrically connected by their controllers in parallel, with the possibility to function jointly and/or independently. At least two nearest windings are located in such a way that two said coil layers belonging to the different windings are separated by an additional layer of electro-insulating material. The coils of said nearest coil layers of different windings are made the same in transparent view, so that the distances between corresponding parts of said coils of said nearest windings are equal to the thickness of said additional layer of an electro-insulating material.

  • Patent number: 6940200
    Abstract: The invention refers to magnetoelectric machines and comprises a rotor made in the form of at least two disks, the magnetized disks have circumferential arrayed like poles and an axially magnetized polygon or cylindrical magnet placed between the disks. The stator comprises a winding selected from the group consisting of a coil winding and a wave winding coils that are distributed over the circumference and are installed predominantly in the space between the rotor poles provides for the possibility of the end face interaction with the rotor poles. Each of at least two disks could be made of a non-ferrous material with embedded magnets, and rotor further comprises ferrous metal plates, each of the plates is attached on an outer surface of each disk and comprises a ferrous metal cylinder for interconnecting a magnetic flux between ferrous metal plates. The rotor could be made as a multi-sectional unit. The disks could be made integral with a magnet in such a manner that they serve as magnet's poles.

  • Patent number: 6903928
    Abstract: An integrated crossflow cooler for electronic components comprises a heatsink with at least two openings, a crossflow blower and an electric drive with a stator and a magnetized rotor. The heatsink comprises a base and heat exchanging means; the base provides thermal contact with the electronic component and the heat exchanging means. The crossflow blower hydraulically connected to one of the openings and comprises a casing rigidly built-in to the heatsink and a drum type impeller comprises magnetic means and serves as a magnetized rotor of the electric drive. The stator made as printed circuit board and rigidly built-in to the casing. The integrated crossflow cooler comprises two types of electric drives—when the magnetic means magnetized in the direction parallel to the axis of rotation and when the magnetic means magnetized in the direction perpendicular to the axis of rotation.
