The invention discloses a heat tube cooling system and power equipment. The heat tube cooling system comprises first heat exchange tubes, a first heat exchange plate, a second heat exchange plate, second heat exchange tubes and a condensing unit, or the heat tube cooling system comprises the first heat exchange tubes, a heat exchange device with a cavity, the second heat exchange tubes and the condensing unit. In the working process, heat conduction between a heating device and the condensing unit can be achieved, and in the overhauling process, the heating device and the condensing unit can be separated and can be respectively maintained. The power equipment comprises the heat tube cooling system, an equipment cabinet and electronic components. By means of the heat tube cooling system and the power equipment, the heating device and the condensing unit can be mutually detached, the heating device is mounted inside the equipment cabinet, the condensing unit is mounted outside the equipment cabinet, during daily maintenance, the heating device and the condensing unit are separated, the inside of the cabinet and the outside of the cabinet can be respectively maintained, and thus the maintaining and cleaning work can be completed rapidly.
