In this work, graphene platelets were introduced into wax of automotive electronic controlled thermostat for the purpose of enhancing the thermal-conductive and improving response performance. Graphene content in ranging from 10 to 20% was added into and mixed with wax for investigating the effect of graphene contents on the performance of automotive electronic controlled thermostat in terms of response time, hysteresis and melting temperature. The experimental results revealed that graphene content in wax contributed to a reduction of response time and hysteresis of automotive electronic controlled thermostat. As a consequence, important improvement in thermal sensitivity , full lift, melting temperature and hysteresis were obtained. We hope that this study may help further the translation of nano-fluid technology from small-scale research laboratories to industrial application in the automotive sector.
