Patent ID: 7330095

Claim:
A cooled multiphase choke assembly comprising: a first coil, a second coil and a third coil for each phase, each first coil, second coil and third coil comprising several turns of winding in such a manner that the turns of winding define a substantially tubular tunnel inside each first coil, second coil and third coil, respectively; and a first cooling element, a second cooling element and a third cooling element, the first cooling element, the second cooling element and the third cooling element each having a coolant channel arranged to receive a flowing coolant, wherein the first cooling element extends in the tubular tunnel of each first coil, the second cooling element extends in the tubular tunnel of each second coil, and the third cooling element extends in the tubular tunnel of each third coil in such a manner that, when the assembly is in use, the same first coolant flow runs inside each first coil, the same second coolant flow runs inside each second coil and same third coolant flow runs inside each third coil, and wherein the first cooling element, the second cooling element and the third cooling element extend substantially linearly, whereby the center lines of the first coils are substantially on the same straight line, the center lines of the second coils are substantially on the same straight line, and the center lines of the third coils are substantially on the same straight line.
