In this paper, the cooling ability of internally Cooled IR Window is numerically studied.The temperature distribution is obtained from unsteady heat conduction equation. It is foundthat the number of cooling holes in the IR window is the most important factor to the coolingability in the case of keeping the same transparent area. The temperature is sensitive theheight of the cooling hole when the height is shorter. Radiation effect on the temperature ofthe window may be neglected. In conclusion, the temperature of IR window can be keepedat proper value by internal cooling.
