The invention relates to a multilayer structure with a temperature control fluid channel (2), which is provided inside a temperature control fluid channel layer (1) on one side thereof or while passing therethrough. According to the invention, a multilayer channel covering (3a, 7, 8) is provided that, on a channel side that is open toward a main side of the temperature control fluid channel layer, seals the temperature control fluid channel from the outside and in a lateral direction in a fluid-impermeable manner. In addition or alternatively, a connection opening starting from a main side of the multilayer structure and extending up to the temperature control fluid channel is provided that serves to receive a connecting piece and hold this connecting piece on the opening edge area in a fluid-tight manner. The one or more adjacent layers, at least in one partial area facing the temperature control fluid channel and extending up to the fluid-tight junction for the connecting piece, is/are made of a fluid-impermeable material or covered therewith or laterally delimited by such a material. The invention is for use, e.g. for multilayer printed circuit boards with cooling channels. |
