Transformer having bow loop in tubular winding
First Claim
1. A transformer comprising:
- a core,a first winding having a plurality of first loops in said core,a secondary winding having a plurality of second loops in said core,said second loops being consecutively interpositioned between said first loops so that one end of each loop of said first winding terminates short of an adjacent end of each loop of said seconary winding,said second winding comprising a tubular conduit, said conduit forming a fluid passageway,means for passing a fluid conduit through said fluid passageway, andwherein said second winding incudes a bow adjacent said end of each loop of said second winding so that the adjacent ends of each loop of the first winding are sandwiched in between said bows.

Abstract
A transformer comprising a core, a primary winding and a secondary winding in which one of the windings, preferably the winding with the least coils, is formed from a tubular member formed in a plurality of coils; in the preferred embodiment of a step down transformer, the secondary winding is formed from a tubular member. A connector block at each end of the secondary winding includes an appropriate fluid passage and means for connecting a fluid coupling to the block so that the inlet and outlet of the fluid circulation system can be secured to the tubular member forming the secondary winding. The loops of the primary coil are interdigitally arranged with the loops of the secondary coil so that the fluid in the secondary coil absorbs heat from both the primary and secondary windings. Each loop of the secondary includes a bow so that adjacent ends of each loop of the primary are sandwiched between the bows. Preferably, the core is made of laminated sections, each laminated section comprising a substantially E-shaped portion, the legs of each E-shaped portion abutting against the legs of the other E-shaped portion in each laminate layer. The primary and secondary coils are wrapped around the center leg of the core.
