Abstract:

A rectifier includes a first electrically conductive cooling member having a first surface for direct contact mounting. A second surface has a first set of diode mounting locations. A diode is mounted within each diode mounting location of the first set and has a terminal extending generally normal from the first surface. An electrical insulator overlies the second surface. A second electrically conductive cooling member has a first surface overlying the insulator, and a second surface having a second set of diode mounting locations. The second electrically conductive cooling member has a plurality of slot openings formed in a radial pattern and extending through the second electrically conductive cooling member from the first surface to the second surface. Cooling fins extend upward beyond the second surface adjacent the slot openings and have formed radii edges such that a high pressure area is formed on one side of the cooling member and a low pressure area is formed on the other side to create a ram effect of air movement through the slot openings to effect enhanced cooling. A diode is mounted within each diode mounting location of the second set.
