【Abstract】 With the method of distributed parameter,a mathematical model for heat sink dynamic parameter has been developed and simulation models have been produced on MATRIXx software.The calculation of the models is performed under the static and dynamic working conditions. As a result,The temperature distribution in different heat sink fields under static working condition is worked out,and the relation between maximum temperature difference and fluid amount as well as temperature dynamic behavior is obtained.All these provide an important basis for optimum design and control research of heat sink and lay the foundation of dynamic simulation of the whole temperature regulating system.更多还原
