This article presents the results of a comparative-experimental research of various methods to intensify heat transfer in the channel. Four different methods of heat exchange enhancement are considered: twisted tape, wire spiral, joint intensifier made of wire tape and twisted spiral, and acoustic method of intensification. The thermal and hydraulic characteristics of various methods of heat exchange intensification are experimentally investigated, and the efficiency of heat exchange intensification is determined. The thermal and hydraulic characteristics of a smooth channel without intensification obtained experimentally under the same conditions were used as a reference. In the course of the comparative analysis of the considered methods of intensification, the most effective ones are found in the range of changes in the Reynolds number from 10000 to 60000. The presented data can be used in the design of heat exchangers.
