Abstract：To search the intensity of heat source and convective heat transfer coefficient in IHCP adopting experiment and Ant colo-ny algorithm.A two -dimensional steady -state heat conduction model with internal heat source was established,the experimental measuring point temperature,which was measured from the surface temperature by infrared camera,was combined with the Ant colony algorithm to inversely calculat the heat source information.The influence of different arrangement of measuring points was also dis-cussed.The results indicated that using thermal infrared imager measuring temperature with the Ant colony algorithm could effectively identify the intensity of heat source and convective heat transfer coefficient.The more number of measuring point on the boundary was, the steps in inverse problem calculation was less,the inversion results were more accurate.Under the condition of the same number of measuring points,measuring points on the whole border points makes it easier for the inverse problem of thermal conductivity inversion to calculate the accurate results than on the part of the border.
