Résumé

Based on a 70 T pulse magnet, this paper sets up the physical model of the distributed pulse heat source, and carries on numerical simulation to the cooling course of the heat source by the analytical method of the numerical heat transfer. Then it gets the temperature changes of every layer of the heat source in the first two minutes and the whole of the cooling course, and calculates the cooldown time of the heat source. The result indicates that the temperature of nearly all layers changes sharply during the first two minutes, especially the first ten seconds of the cooling course, and the whole cooling course is proved to be very long. On the last stage it is the temperature gradients of each layer that play a decisive role on the speed of cooling, instead of the heat conductive performances.
