The utility model relates to an anti-collision door upper guide rail which comprises a guide rail body, sliding grooves are formed in the two sides of the bottom end of the guide rail body, electric heating plates are fixedly embedded in the top ends of the sliding grooves, heat conduction plates are further fixedly embedded in the inner walls of the sliding grooves, a plurality of heat conduction protrusions are arranged at the bottom ends of the heat conduction plates, and the heat conduction protrusions extend into the sliding grooves. When the guide rail is applied to an ice-cold area or a cold storage door, the electric heating plate is started, the electric heating plate heats the heat conducting plate, heat generated by the heat conducting plate is rapidly transferred to the heat conducting protrusions, the heat conducting protrusions can heat the sliding groove, the door is prevented from being locked in the guide rail body, and the heat conducting plate is prevented from being blocked by the heat con
