Brazed joint between a cooling fluid box and an armature bar
First Claim
1. A brazed joint between an armature bar and a cooling fluid box, the joint comprising:
- a cooling fluid box with an inboard end, an opposing outboard end, a first side wall, and a second side wall, the first side wall opposing the second side wall;
a plurality of conductor strands extending into the inboard end of the cooling fluid box, wherein the plurality of conductor strands are arranged in a plurality of columns;
at least one side wall spacer wedged between the plurality of conductor strands and at least one of the first side wall and the second side wall, wherein the at least one side wall spacer has a first tapered width that tapers in a direction from the inboard end of the cooling fluid box toward the outboard end of the cooling fluid box; and
at least one middle spacer wedged between at least a first column of the plurality of conductor strands and a second column of the plurality of conductor strands, wherein the at least one middle spacer has a second tapered width that tapers in a direction from the outboard end of the cooling fluid box toward the inboard end of the cooling fluid box.

Abstract
A brazed joint between a cooling fluid box and an armature bar can comprise a cooling fluid box, a plurality of conductor strands, at least one side wall spacer, and at least one middle spacer. Each side wall spacer can have a tapered width and can be wedged between the plurality of conductor strands and an interior side wall of the cooling fluid box. Each middle spacer can have a tapered width and can be wedged between two columns of the conductor strands. The side wall spacers can taper in a direction opposite the taper of the middle spacers. In one embodiment, the cooling fluid box can move around the conductor strands. Each side wall spacer can be positioned against an interior surface of the cooling fluid box. Each middle spacer can be positioned between columns of conductor strands. The cooling fluid box can be withdrawn to a final position.

10. A method of forming a brazed joint between an armature bar and a cooling fluid box, the method comprising the steps:
-
moving the cooling fluid box, with respect to a plurality of conductor strands, around the plurality of conductor strands, so the plurality of conductor strands enters through a first end of the cooling fluid box; positioning at least one tapered side wall spacer against at least one interior surface of the cooling fluid box; positioning at least one tapered middle spacer between at least two conductor strands from the plurality of conductor strands; withdrawing the cooling fluid box and the at least one tapered side wall spacer, with respect to the plurality of conductor strands, to a final position at which the plurality of conductor strands, the at least one middle spacer, and the at least one side wall spacer are wedged between the at least one interior surface and at least one opposing interior surface of the cooling fluid box opposite the at least one interior surface. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
