A New Temperature Compensation Method For Circular Cavity Resonator Using Low Conductivity Cooling Water System Based On Convection Heat Transfer

A novel temperature compensation method is presented, in which we used the Low Conductivity Water Cooling System. This paper, studied the temperature compensation in resonant cavities In this method, heat load and heat exchange has been measured and according to this, the mass flow rate has been maintained. Temperature compensation depends on the three major parameters- cooling area, mass flow rate, temperature of the chiller . By using these parameters, we can calculate the heat transfer from cavity to water . If we want to remove all the heat, heat load should be equal to heat transfer. In this method, by maintaining mass flow rate, we can simply reduce the heat load. This paper gives an expression for the temperature drift of resonant frequency. Simulation results  confirms the feasibility of the proposed design approach. This temperature compensated cavity design is feasible and can substantially reduces the temperature drift of circular cavity resonator.
