1. A switching power supply having a primary clock-pulse control comprising:
- a closed housing;
a primary power supply circuit with first heat producing components within said housing;
a secondary power supply circuit with second heat producing components within said housing;
a ventilation conduit disposed within said housing for communicating with air outside the housing, said air acting as a cooling medium;
a forced-air cooling means disposed within said housing, said cooling means having first and second cooling elements mounting said first and second heat producing components, respectively, said forced air cooling means projecting into said ventilation conduit and inaccessible from outside of said housing; and
,insulating means separating said first from said second cooling elements.

Abstract
Power supplies are known, in particular power supplies under primary clock-pulse control, that comprise a closed housing for the primary and secondary circuits, and a forced-air cooling means to cool the heat-producing components of the circuits. A power supply is proposed in which additionally there is a ventilation conduit in communication with the air outside the housing to serve as a cooling medium. The cooling means also comprises at least one cooling-unit element, on which the heat-producing components are mounted, and a portion of said element projects into the ventilation conduit and is electrically isolated by insulating means.
