Abstract: An integrated motorized pump (1) comprising an impeller (2) mounted on an axle (3), two magnetic drives (6) electromagnetically coupled to an electric motor (7), a casing (8) with a flowing space (9), an inlet channel (10) and an (11). The impeller (2) has circumferential arrayed magnetic means (13) magnetized in the direction parallel to the axle (3). The electric motor (7) comprising said impeller (2) as a rotor, and two stator plates (20). The stator plates (20) are covered with a liquid tight coating and comprise circumferential arrayed coils (21) etched on circuit board metal layers (22). Each magnetic drive (6) comprises a stator (14) with circumferential arrayed coil windings (16) and two magnetized disks (15). The magnetized disks (15) are mounted on the axle (3) perpendiculary to it and have a circumferential carry of radially extending poles (17).

Abstract: An integrated cooler for electronic devices comprises a heat exchange element, a heat transferring element and a blower with an electric drive. The heat exchange element comprises a base and heat exchanging means. The electronic device directly thermally connected with the base or the heat exchanging means by the heat transferring element. The blower comprises an inlet, an outlet and a drum type impeller comprises a disk with blades mounted on an axle fixed perpendicularly to the base. The heat exchanging means located at the inlet and/or at the outlet, thus ambient air flows through the inlet, the impeller and the outlet in a series way and in the directions perpendicular to the axle, so that the blower is a crossflow type blower. The electric drive comprises a rotor and a stator. The rotor made as the impeller having circumferential arrayed magnetic means. The stator comprises circumferential arrayed coils.

Abstract: An integrated drive motor assembly is described where the functional components of a powered device are an integral part of the motor. The assembly comprises a brushless, direct current drive motor having a ring-shaped stator with flat printed circuit coil windings, a ring-shaped permanent magnet rotor, and an electronic commutator circuit. Functional embodiments of the assembly include a rotor impeller and an axial flow fan.

Abstract: The integrated cooler for electronic devices of this invention provides at least one heat exchange element, at least one heat transferring element, a blower and an electric drive. The at least one heat exchange element comprises a heat spreading base and heat exchanging means made on a surface of the base. The heat spreading base providing thermal contact with the at least one heat transferring element. The blower comprises a blower inlet and a blower outlet, which are directly connected to ambient air, so that the integrated cooler for electronic devices becomes a hydraulically sealed unit and a drum type radial impeller that is mounted on an axle and comprises at least one impeller disk and blades attached to the at least one impeller disk. The blower is positioned on the heat exchange element so that the heat exchanging means being located at the blower outlet and/or at the blower inlet. The electric drive comprises a rotor and at least one stator.

Abstract: According to the present invention, a cooler for electronic devices comprises a heat exchange element, a blower with a radial type impeller, and an electric drive. The heat exchange element comprises heat exchanging means made on one surface of said heat exchange element while its other surface provides thermal contact with a heat-radiating means. The radial type impeller has a shroud with a flat surface from one side, a hub and brackets and a central inlet between the shroud and the hub, the brackets connect the hub with the shroud. The radial type impeller is positioned on the heat exchange element so that the heat exchanging means being surrounded by the radial type impeller and a cooling gas flows to the radial type impeller from the central inlet through the heat exchanging means.
