Rotationally symmetrical circulating heat source loop heat pipe

The invention provides a rotationally symmetrical circulating heat source loop heat pipe. The pipe comprises a middle evaporating pipe, a left collecting pipe, a right collecting pipe and a pipe group, the pipe group comprise the left pipe set and the right pipe set, the left pipe set communicates with the left collecting pipe and the middle evaporating pipe, the right pipe set communicates with the right collecting pipe and the middle evaporating pipe, and therefore the middle evaporating pipe, the left collecting pipe, the right collecting pipe and the pipe group form heating fluid closed circulation, and the heat source is arranged in the middle evaporating pipe. And the heating source of the middle evaporation pipe adopts an intermittent heating mode, namely, heating is firstly performed for a period of time, then heating is stopped for a period of time, then heating is performed, and circulation is performed ceaselessly. According to the loop heat pipe, heating is conducted through the time variability,
