Patent number: 6897583Abstract: In an electrical machine, in particular a generator for a motor vehicle, having a housing (2), a rotor (6), supported rotatably in the housing (2) about a pivot axis (5), at least one fan wheel (20), connected to the rotor (6), for generating a cooling air flow (22, 22?, 22?) from at least one intake opening (37; 37?; 37?) disposed in the housing (2) to at least one outlet opening (24) disposed in the housing (2), and at least one regulator chip (31), disposed on a chip holder (30), for regulating the current generation, it is provided that the chip holder (30) is disposed such that it is bathed at least in part directly by the cooling air flow (22, 22?, 22?). As a result of this arrangement, it is attained that a very high heat transfer coefficient is present, because of the high flow speed of the cooling air flow (22, 22?, 22?).Type: GrantFiled: February 16, 2002Date of Patent: May 24, 2005Assignee: Robert Bosch GmbHInventors: Andreas Doeffinger, Achim Henkel, Frank Himmler, Thomas Bilsing

Patent number: 6812604Abstract: The invention relates to an electrical machine, preferably an alternator (10) for motor vehicles, comprising a rectifier assembly (11a) that is fixed to an end shield (23) of the machine. Said rectifier assembly is cooled by a fan (27) that operates in the end shield (23), the diodes being positioned on a negative connecting plate (15) and a positive connecting plate (17) of the rectifier assembly (11). The aim of the invention is to evacuate the dissipated heat from the rectifier assembly (11a) in an advantageous manner. To achieve this, the rectifier assembly is located in an opening in the front face (32) of the end shield (23) and is connected in an electrically and thermally conductive manner by one of its two connecting plates (15 and 17) to a cooling body (33), which is connected to the exterior of the end shield (23) and covers the opening (32).Type: GrantFiled: October 27, 2003Date of Patent: November 2, 2004Assignee: Robert Bosch GmbHInventors: Horst Braun, Holger Scholzen, Peter Urbach, Holger Haussmann, Dana Keppeler, Thomas Bilsing

Patent number: 6285100Abstract: An electrical machine is proposed, preferably a rotary current generator (10), with a rectifier component (26) at the rear end area of its end shield (11), in which dissipation of waste heat is to be improved. Positive and negative heat sinks (27, 28) with the positive and negative diodes (31, 32), respectively, are screwed to the end shield (12) so as to be sandwiched together with a printed circuit board (30) for the connection between diodes and winding connections (17a) with the inclusion of an insulating plate (29). The upper heat sink (27) has a plurality of cooling air openings (38) arranged next to one another at the inner circumferential area for a cooling air flow generated by the fan of the machine. In order to improve the dissipation of heat, axial cooling fins (39) are formed on at least at some of the cooling air openings (38) of the upper heat sink (27).Type: GrantFiled: August 9, 1999Date of Patent: September 4, 2001Assignee: Robert Bosch GmbHInventors: Gerhard Pflueger, Ludwig Bolz, Uwe Knappenberger, Thomas Bilsing
