Making use of good drive characteristics of paraffin material, a type of thermal-sensitive valve applied in adaptive cooling system of large-scale vehicle was designed.In order to disclose the response problem of the thermal-sensitive valve to temperature change, by means of the finite difference computational method of numerical heat transfer theory, the mathematic models of two-dimension steady-state and unsteady-state temperature field of its temperature-sensing component were built, and the simulation calculations of two mathematic models were implemented using MATLAB software.The steady-state temperature field and transient state temperature fields of some typical time were acquired through simulation, and on the basis of analyzing these temperature fields, it can be known that the response of temperature-sensing component to temperature

changes can meet the demands of adaptive cooling system of large-scale vehicle. 
