Influenced by the geometry and boundary condition’s complexity of the model, as to the heat conductor with complicated shape or non-linear boundary condition, the model must be simplified a lot, before it’s heat dissipating capacity can be calculated with the mathematic method, the course is quite complicated, and the error is large. Utilizing finite element software, an universal program has been worked out by the APDL, and it can output the heat dissipating capacity of appointed surfaces in analysis software. The program is so powerful that it can calculate the heat dissipating capacity of heat conductor in which the heat transfer two-dimensionally or three-dimensionally even if the heat conductor is anisotropic, which is difficult to calculate with the mathematic analysis method. The method mentioned in the paper can diminish the inaccuracy caused by the predigestion with the mathematic analysis method. The calculation principle of the program was introduced in detail. Comparing the result of the program with that got by mathematic method, it was indicated that the calculation error of program is smaller than 1%.
