Shaft sealing arrangement

Abstract: The invention relates to a fan arrangement, comprising an electric motor (2) having a motor shaft (3), a fan wheel (4) driven by the motor shaft and arranged in a housing, at least one shaft bearing (10), a shaft sealing arrangement (1), which has the shape of a crucible, wherein the at least one shaft bearing is inserted in the shaft sealing arrangement, which has a sealing opening (8) for the motor shaft to pass through.

Air blower device

Abstract: The utility model relates to an air blower device (1), it includes: impeller (2), it has axial sunction inlet (21), and this sunction inlet is formed by at least district section nature earth shifterlid impeller blade (4) apron (3), suction nozzle (6), its longshore current are moved direction of connection and are in locate to stretch into in coincidence district's section (5) in the section ofdistrict nature ground at least in impeller (2) upper reaches, this suction nozzle in the sunction inlet of impeller (2), wherein be formed with nozzle clearance (7) encircleed between apron (3) of suction nozzle (6) and impeller (2), blowout mouth (8), it upwards separates with impeller (2) and suction nozzle (6) and upwards centering on in week and arrange in the footpath each other. The utilitymodel discloses an effectiveness coefficient of impeller (2) has been improved in air blower device (1), can can't harm the fluid that the transport was treated in the lost territory guide as far aspossible.

Arrangement with electric motor has piece of sheet with conducting tracks for connecting motor to second part and plastic molded on at least in regions to form insulation between conducting tracks.

Abstract: The arrangement has an electric motor with at least one piece of sheet with conducting tracks for connecting the motor (11) to the second part (24) and has plastic molded on at least in regions to form insulation between the conducting tracks (52,54,56). The first part (20) has regions (102,106) between two or more adjacent conducting tracks in which both parts of the sheet piece and molded plastic are removed to electrically isolate the tracks. An independent claim is also included for the following: (a) a method of manufacturing an inventive arrangement.

Method & arrangement for cooling a substrate, particularly a semiconductor

Abstract: In this method, a refrigerant ( 52 ) is compressed ( 32 ) in a refrigerating circuit, then condensed by cooling in a condenser ( 44 ), then expanded in a throttle valve ( 62 ) and delivered in the expanded state, in the form of wet vapor ( 52 ), to an evaporator ( 60 ) that is in thermally conductive contact with a substrate ( 12 ) to be cooled. The cooling process thus operates similarly to a liquid cooling process, but with a higher mean logarithmic heat transfer temperature difference, which allows lower temperatures of the substrate ( 12 ) to be achieved and makes possible a better heat transition coefficient, since the refrigerant is present as wet vapor. A corresponding arrangement is likewise described.
