ABB patent application drawingU.S. patent application 20170234389 (Applicant ABB Technology Ltd., Zurich, Switzerland):

"A pressure plate for a friction coupling such as a clutch or brake system is disclosed in the present application. The pressure plate includes one or more pockets with a phase change material disposed therein [76]. The phase change material operates to absorb and release heat when the friction coupling cycles between activation and deactivation so as to minimize a maximum temperature of the pressure plate."
