Heat sink for car alternator rectifier bridge and alternator rectifier unit having such a heat sink

摘要

The heat dissipater for the bridge rectifier used on a vehicle alternator comprises a sector (3a) of a thermally conducting material which is intended to be attached to the alternator. Within this there are seatings to receive the positive diodes (2) of the bridge rectifier. There is also a second sector (3b) also made of thermally conducting material and attachments for fixing this second sector to the first (3a) at points adjacent to the seatings within which the diodes are accommodated. The sectors may provide four seatings for the respective diodes of the bridge rectifier, and the attachment may be by means of screws.
