Abstract

A gradient coil system for a magnetic resonance tomography apparatus has a layer structure including a gradient coil layer and a cooling layer. The cooling layer is fashioned as a plate heat exchanger, composed of plates, for cooling the gradient coil layer. In this way, a highly efficient cooling of the gradient coil layer is achieved with a lower structural height compared to conventional tubular configurations.
