Mirror-symmetry loop heat pipe for water level difference control vibration

The invention provides a loop heat pipe. The loop heat pipe comprises a middle evaporating pipe, a left collecting pipe, a right collecting pipe and a pipe group, wherein the pipe group comprises a left pipe group and a right pipe group; the left pipe group communicates with the left collecting pipe and the middle evaporating pipe, and the right pipe group communicates with the right collecting pipe and the middle evaporating pipe, so that the middle evaporating pipe, the left collecting pipe, the right collecting pipe and the pipe group form a heating fluid closed cycle; a heat source is arranged in the middle evaporation pipe; a liquid level sensing element is arranged in the middle evaporation pipe and used for detecting the liquid level of fluid in the middle evaporation pipe; the liquid level sensing element is in data connection with a controller; and the controller extracts the liquid level data according to a time sequence, obtains the liquid level difference or the accumulation of the liquid level di
