Phase change material and water cooling temperature controlling methods for embedded smart components based on GMM

In order to overcome the thermal error caused by the rise of embedded smart components temperature based on Giant Magnetostrictive Materia（ GMM）,a new temperature control method combined with phase change material and water cooling were presented. The theory of the new temperature control method were introduced and the specific design of the temperature control device were given. By using the finite element method,the model of temperature field based on GMM embedded smart components were build. Steady state thermal analysis was made on the model of temperature field based on GMM embedded smart component on the two conditions with and without temperature control device,and dynamic loading experiment were also carried out. The temperature control method combined with phase change material and water cooling can effectively suppress the temperature rise,and it is suit for embedded smart components which are based on GMM to work on high current and micro- precision machining.
