An electrothermal rack of a hair dryer includes a main body including a plurality of support wings each having a mediate portion formed with a positioning section formed with a plurality of inner insertion recesses. Each of the support wings has an outer side formed with a protruding plate formed with a plurality of outer insertion recesses. Each of the support wings is formed with a slideway between the positioning section and the protruding plate. Thus, the electrothermal body forms a multi-loop inner layer and a multi-loop outer layer around the support wings to increase the heating area of the electrothermal rack, thereby enhancing the heating efficiency of the hair dryer.
