Modular power supply
First Claim
1. Power supply apparatus connectable with an external power input for deriving a regulated D.C. source, comprising:
- a heat exchange channel extending along a flow axis between first and second openings and having at least one outwardly disposed heat transfer surface defining assembly;
at least one power converter module having a heat sink surface, an input connector assembly and regulated output connectors extending outwardly in a given direction therefrom, said heat sink surface being coupled in thermal exchange relationship with a said channel heat transfer surface and arranged thereon to position said regulated output connectors in an orientation wherein said given direction is transverse to said flow axis; and
a fan assembly mounted in air flow establishing relationship with said heat exchange channel first opening and directing air flow along said axis from said first opening through said second opening.

Abstract
Modular power supply apparatus wherein a plurality of d.c.-to-d.c. converters are coupled to an internally structured heat exchange channel through which fan driven air is passed in an unobstructed manner along a flow axis. Each of the converter modules is combined with a dedicated module circuit board which provides regulated output terminals in an orientation or direction arranged transversely to the flow axis. The opposite end of the module circuit boards are plugged into a main interconnect circuit board positioned along one side of the heat exchange channel. A support channel is provided outwardly of the main interconnect circuit board within which principal components of supporting circuitry are contained.
