Studies on the Temperature Difference of a Component under Different Heat Sources

Article Preview

Abstract:

After the description of finite element model of three-dimensional heat conduction, the software FLOEFD is used to simulate a components temperature fields under various heat sources, to get the temperature difference curves and to analysis the difference between them. It comes out that when the power of heat source changes as a triangular curve, corresponding temperature difference is lower than that of sinusoidal power curve, but larger than that of constant power; Change rate of temperature difference of triangular power curve is lower than that of sinusoidal and constant power, but larger than that of square power curve. The distinction of temperature difference is caused by the different change-rate of inputting heat; the distinction of changing rate of temperature difference is caused by the different changing rate of heat source power.
