Abstract
To simplify manufacture and assembly of automotive alternator-type rectifier combinations, the rectifier structure is made by pressing rectifier diodes, in groups of opposite polarity, into identical cooling plates which are constructed in essentially rectangular form with one corner taken out, the rectangular forms being crossed and located in parallel planes, stacked one above each other, so that the interconnecting links between the positive and negative diodes on the assemblies will have equal distance from each other, and the cooling plates will be identical.
Claims15
Rectifier assembly to rectify the output of a three-phase alternator comprising
- first and second heat sink cooling plates (11, 13);
- a first group (12) of positive rectifying diode rectifiers secured in electrical and thermal contact to the first plate (11);
- a second group (14) of negative rectifying diode rectifiers secured in electrical and thermal contact with the second plate (13);
- and connecting leads (19) interconnecting the diode groups and the alternator phase windings (121),
- wherein, in accordance with the invention,
- the first and second heat sink plates (11, 13) are flat, elongated, essentially rectangular plates located radially symmetrically, and axially staggered with respect to the shaft (C) of the alternator and positioned in crossed relation with respect to each other.
