The invention relates to a heat pipe radiator working in a revolution motion state. The heat pipe radiator comprises an evaporator segment, an insulation segment and a condensation segment, and the radiators are uniformly distributed on a rotor electrical conductive copper disc along the peripheral direction. The heat pipe radiator is characterized in that the evaporator segment, the insulation segment and the condensation segment form a heterotypic ring copper tube structure, and the two ends of the evaporator segment and the condensation segment are connected by virtue of the insulation segment; the evaporator segment is of an arc shape, and the arc bending diameter is the same as the diameter of a distribution circle; and the condensation segment is also of an arc shape, and the arc bending diameter is the same as the diameter of the distribution circle and opposite to the arc direction of the evaporator segment. Compared with the prior art, the heat pipe radiator provided by the invention has the beneficial effects that a working medium liquid in the evaporator segment can be uniformly distributed under the centrifugal force action, which is beneficial to absorption of heat; and when the working medium in the condensation segment is subjected to the centrifugal action, a tangential component is generated along the axes direction of the pipe based on the shape of the condensation segment, the working medium completely flows into the two ends of a condenser tube under the action of the tangential component, thereby meeting the normal working condition of the heat pipe under the revolution motion state.
