Definitions

  • a generator for a motor vehicle in which a voltage regulator is electrically connected to the slip ring arrangement.
  • the generator has a cooling channel that runs past a voltage regulator.
  • the voltage regulator comprises a housing, a printed circuit board and a regulator chip, which are mounted on a mounting plate.
  • the controller mounting plate is directly adjacent to the cooling air channel.
  • the cooling air duct is created by a spacer element that spaces the mounting plates from the generator housing.
  • a disadvantage of this embodiment is that the circuit board with the controller chip is attached to an additional mounting plate. The heat transfer to the sucked-in cooling air is restricted by the mounting plate on which the controller chip is mounted. The cooling air flow does not come into direct contact with the circuit board or the controller chip.
  • the spacer creates a larger installation space, which has a negative effect on the size of the generator. There are also higher manufacturing costs due to the additional material costs and the assembly costs.
  • the chip carrier 30 is located in the recess 26 of the slip ring bearing plate 25, the chip carrier 30 being thermally insulated with respect to the slip ring bearing plate 25 with a plastic layer that forms the thermal insulation 33. A heating of the controller chip 31 by the slip ring end shield 25 is achieved by this insulation. tion 33 prevented.
  • the underside 21 of the chip carrier 30 facing the slip ring-side fan wheel 20 protrudes somewhat from the recess 26 into the interior of the generator 1. Between the chip carrier 30 attached in the recess 26 and the rotor shaft 7 there is a separate suction Opening 37 for a cooling air flow 22.
  • the controller chip 31 is on a lead frame or attached to a busbar, which run directly in the cooling air stream 22.
  • a leadframe is originally understood to mean busbars interconnected by a frame. The cooling of the controller chip 31 is further improved due to this arrangement.

Abstract

L'invention concerne une machine électrique, en particulier un générateur pour un véhicule à moteur, comprenant une carcasse (2), un rotor (6) monté en rotation autour d'un axe de rotation (5), au moins une roue de ventilateur (20), solidaire du rotor (6), pour la production d'un courant d'air de refroidissement (22, 22', 22'') d'au moins une ouverture d'aspiration (37 ; 37' ; 37'') ménagée dans la carcasse (2) vers au moins une ouverture d'échappement (24) ménagée dans la carcasse (2), et au moins une puce de réglage (31) disposée sur un support (30) pour la régulation de la production du courant d'air, caractérisée en ce que le support de puce (30) est disposé de telle façon qu'au moins une partie du courant d'air de refroidissement (22, 22', 22'') circule directement autour du support de puce. L'agencement selon l'invention permet d'obtenir un coefficient de transmission de chaleur très élevé en raison de la vitesse élevée d'écoulement du courant d'air de refroidissement (22, 22', 22'').
