Abstract: A gradient coil assembly for a magnetic resonance imaging system (1) includes at least one gradient coil (2) and a cooling arangement for cooling the gradient coil (2). The gradient coil (2) includes a solid electrical conductor material forming one or more conductor lines (21, 31, 41) which are in direct contact with each other. The cooling arrangement includes a cooling channel (22, 32, 42) for guiding a cooling fluid (10). The cooling channel (22, 32, 42) is arranged outside along the one or more conductor lines (21, 31, 41) in such a way that in a cross-sectional view one single continuous interface line between the cooling channel (22, 32, 42) and the one or more conductor lines (21, 31, 41) is formed. In this way efficient cooling of the gradient coil (2) may be achieved.
