The present invention provides a method for constant and rapid heat dissipation and thermal indication for railway wheel set assemblies. The method comprises assembling a vehicle wheel set by mounting bearings and wheels on an axle with interference fit and mounting bearing adapter onto bearings. Heat pipes are embedded within the said vehicle wheel set. The heat pipes provide heat sinks for the vehicle wheel set assembly causing a fluid within the heat pipe to vaporize on sections of heat pipe more adjacent to the bearing assemblies and to condense on other sections of heat pipes more adjacent to the heat dissipation areas. The heat dissipation area can be either the surfaces of the wheel set assembly or the surfaces of additional cooling fins mounted on the wheel set assembly. The embedment of heat pipes within the wheel set assembly thus enables constant cooling for bearing assembly. The heat is transferred within the heat pipes from the bearing assemblies to the heat dissipation areas, then to the atmosphere. Meanwhile, the rises of temperature in the thermal indication areas that are included in the heat dissipation areas and are monitored by either wayside hot box detectors or onboard thermal sensors, provide precise thermal indications of the interior running conditions of the bearing assemblies.
