Narrow profile transformer having interleaved windings and cooling passage

DETAILED DESCRIPTION The present invention is defined by the appended claims with specific embodiments being shown in the attached drawings.
For the purpose of summarizing the invention, the invention relates to an improved narrow profile transformer for transferring electric power from an electrical power source to an electrical load.
The improved narrow profile transformer comprises primary winding means being spirally wound with all portions of the primary winding means intersecting a geometric plane extending through the improved narrow profile transformer.
Secondary winding means is interleaved with the primary winding means with all portions of the secondary winding means intersecting the geometric plane.
Insulation means is interposed between the primary winding means and the secondary winding means.
A transformer core inductively couples the primary winding means to the secondary winding means.
Input connection means electrically connects the primary winding means to the electrical power source whereas output connection means electrically connects the secondary winding means to the electrical load.
The secondary winding means is secured relative to the primary winding means for maintaining the relative position therebetween.
In a more specific embodiment of the invention, the primary winding means is spirally wound radially outwardly with all portions of the primary winding means intersecting the geometric plane extending through the improved narrow profile transformer.
The secondary winding means includes a plurality of secondary turn elements with shunt means interconnecting the plurality of secondary turn elements in a parallel relationship.
The insulation means comprises a polymeric coating affixed to at least one of the primary winding means and the secondary winding means.
In one embodiment of the invention, the primary and second winding means are encapsulated within a polymeric material for maintaining the relative position therebetween.
The transformer core comprises a ferrite core for inductively coupling the primary winding means to the secondary winding means
