Liquid-cooled brake resistor (Fig 3) for use in electric vehicles, comprising a metallic block 3 having a inlet (4, fig 3), outlet (5, fig 3) and internal flow path (6, fig 2) to facilitate cooling of the resistor. The brake resistor has at least one flat resistor 7 located with its main plane parallel to the face of the block 3, and at least one thermally conductive, electrically insulating layer 9 placed between the block and the resistor. The resistor 7 comprises a retaining means which subjects the resistor to an uniform force against the face of the block, whilst an expansion guide partially or fully surrounds the resistor to confine expansion of the resistor in its main plane. The expansion guide is preferably manufactured from phlogophite mica paper and is preferably no thicker than the thickness of the resistor 7. |
