Abstract:
1. A gradient coil system for a magnetic resonance apparatus comprising: a plurality of gradient coils each having a current supply cable; a cooling tube in thermal contact with at least one of said gradient coils, said cooling tube being adapted to contain a flowing coolant therein said cooling tube being comprised of a flexible, thermoplastic material augmented with a filler, said thermoplastic material having a heat conductivity greater than 0.5 W/mK; a carrier plate, said cooling tube and said gradient coils being attached to said carrier plate at a same side of said carrier plate, and said cooling tube being wound on said carrier plate in a pattern selected from the group consisting of a spiral pattern and a serpentine pattern; and a sealing compound encapsulating said cooling tube, said gradient coils and the current supply cables on said carrier plate to form a unit.
