Abstract
A conductive coil for an electric application having a cooling channel for a coolant liquid or gas. The coil includes a wire winding of a plurality of wire turns. The wire winding is compressed about a cooling channel which is disposed between adjacent turn segments of the plurality of wire turns. The wire winding is formed and pressed against a shaping element to form the coolant channel within the compressed winding.
Claims20
A coil for an electric application, the coil comprising:
- a winding including a plurality of superposed winding turns of at least one wire fully wound a plurality of times about a winding axis, the winding having a first turn end and a second turn end on an opposite end of the first turn end, wherein the winding comprises a cooling channel extending a length of the winding and disposed between adjacent turn segments of the plurality of superposed winding turns, the cooling channel including a first end opening at the first turn end and configured to receive a coolant flow, and the cooling channel including a second end opening at an opposite end of the cooling channel.
A method of forming a coil for an electric application, the method comprising:
- winding a wire about a bobbin element to obtain a wire winding including a plurality of superposed winding turns of the wire fully wound a plurality of times about the bobbin element, the winding having a first turn end and a second turn end on an opposite end of the first turn end;
- compressing the wire winding against a shaping element, wherein the shaping element forms a channel groove in the wire winding and disposed between adjacent turn segments of the plurality of superposed winding turns, the channel groove including a first end opening at the first turn end and configured to receive a coolant flow, and the channel groove including a second end opening at an opposite end of the cooling groove.
