Abstract
The disclosure relates to a gradient coil unit with a primary coil having at least one spiral conductor structure that is formed by an electrical conductor configured as a hollow conductor with a hollow region, which electrical conductor is subdivisible into two portions serially connected to one another, the electrical conductor is arranged spirally in turns in such a manner that two adjacent turns of the electrical conductor are to be associated with the two portions that differ from one another, and with two cooling circuits, wherein a cooling circuit is in each case provided for cooling a portion.
Claims11
A gradient coil unit, comprising:
- a primary coil comprising a spiral conductor structure formed by an electrical conductor configured as a hollow conductor with a hollow region,
- wherein the electrical conductor comprises two or more portions serially connected to one another, and
- wherein the electrical conductor is arranged spirally in turns such that two adjacent turns of the electrical conductor are associated with two of the two or more portions that differ from one another;
- a first cooling circuit having a first cooling duct comprising the hollow region of a first portion of the two or more portions,
- wherein the first cooling duct has a first incoupling point into the hollow region of the first portion and a first outcoupling point out of the hollow region of the first portion that is configured to pass a first cooling medium through the first cooling duct in a first direction from the first incoupling point to the first outcoupling point;
- and
- a second cooling circuit having a second cooling duct comprising the hollow region of a second portion of the two or more portions,
- wherein the second cooling duct has a second incoupling point into the hollow region of the second portion and a second outcoupling point out of the hollow region of the second portion that is configured to pass a second cooling medium through the second cooling duct in a second direction from the second incoupling point to the second outcoupling point,
- wherein the first direction and the second direction are oriented opposingly, and
- wherein the first cooling circuit and the second cooling circuit are interconnected separately from one another or parallel to one another.
