A heat pipe vacuum switch comprises a fixed contact (1), a moving contact (2), a conductive rod and a heat pipe system for cooling. The heat pipe system is comprised of an evaporating pipe, a connecting pipe and a radiator; the evaporating pipe is metallic pipe located in the vacuum arc chute and sleeved at outside of the conductive rod; the space between the evaporating pipe and the conductive rod is liquid storage space; the liquid storage space is filled with cooling liquid; the radiator is located out the vacuum arc chute and is hollow metallic cavity; the connecting pipe is metallic pipe; one end is connected with the evaporating pipe, the other end is connected with the radiator; inner cavities of the connecting pipe, the evaporating pipe and the radiator are communicated. The heat pipe system is simultaneously arranged at one side of the fixed contact (1) and one side of the moving contact (2), or is only arranged at one side of the fixed contact (1) or the moving contact (2).
