Abstract (en)
The present invention concerns a magnetic core with an integrated liquid cooling channel and a method to make the same. The method comprises the steps of:- inserting a part of a soluble material that have a shape that corresponds to a liquid cooling channel in a mold, the part of the soluble material having an inner channel,- pouring a mix of magnetic powder, binder and additives in the mold.- pressing the mix of magnetic powder, binder and additives,- curing the pressed mix of magnetic powder, binder and additives,- injecting a solvent in the inner channel in order to dissolve the soluble material.
