1. An automotive clutch provided with a cooling fin arrangement, the clutch comprising a surface exposed to a cooling fluid, the surface in heat conductive relation with a viscous fluid between at least two clutch elements, a plurality of cooling fins defining fluid channels for the flow of the cooling fluid between the fins effective to transfer heat from the viscous fluid to the cooling fluid, andprotuberances on the surfaces of the cooling fins extending a distance into the cooling fluid flow effective to induce non-laminar flow therein, the protuberances having at least one edge oriented substantially perpendicular to the flow of the cooling fluid whereby a surface of said protuberances which is exposed to said fluid flow is arranged in angular relationship to said fluid flow, the non-laminar flow effective to increase the transfer of heat from the viscous fluid relative to the transfer of heat from the viscous fluid by a laminar flow through the channels.
