Abstract
A heat sink of an alternating current generator for a vehicle has a heat sink body formed from aluminum die-cast. An insert member is provided on the heat sink body and a diode is provided on the insert member. The insert member (1) surrounds the side walls of the diode, (2) is (a) a metal having a good solderability other than aluminum or (b) a metal having a good solderability adhered onto a base metal other than aluminum, and (3) provides a solder connection between the diode and the heat sink body.
Claims4
A rectifier of an alternating current generator for a vehicle, said rectifier comprising:
- a heat sink body formed from aluminum die-cast and having a mounting portion;
- an insert member provided on said mounting portion;
- and
- a diode having, a mounting face from which side walls extend, said mounting face provided on said insert member, wherein said insert member
- (1) surrounds said side walls of said diode,
- (2) is one of (a) a metal having a good solderability other than aluminum and (b) a metal having a good solderability adhered onto a base metal other than aluminum, and
- (3) provides a solder connection between said diode and said heat sink body.
A rectifier of an alternating current generator for a vehicle, said rectifier comprising:
- an insert die-cast body having a heat sink body formed from aluminum and die-cast onto an insert member;
- and
- a diode soldered to said insert member, wherein said insert member is one of (a) a metal having a good solderability other than aluminum and (b) a metal having a good solderability adhered onto a base metal other than aluminum.
