The utility model provides a heat pipe, a flat heat pipe, a radiator, an LED lamp, a refrigerator and a vehicle, and relates to the technical field of heat pipes, at least one outer surface of the heat pipe is of a plane structure, a cavity wall of the heat pipe is provided with a round hole groove, the round hole groove is provided with an opening communicated with a heat pipe cavity, the diameter phi of the round hole groove is larger than or equal to 0.3 mm and smaller than or equal to 1.2 mm, and the diameter phi of the round hole groove is larger than or equal to 0.3 mm and smaller than or equal to 1.2 mm. The cavity and the round hole groove of the heat pipe are integrally formed by aluminum or aluminum alloy in an extrusion mode. By designing the size of the round hole groove and arranging the opening communicated with the cavity of the heat pipe on the round hole groove, the heat exchange area of the vapor phase heat transfer working medium and the pipe wall is further increased, the backflow capacity
