Circular heating pipe

Abstract

The invention relates to a circular heating pipe. The circular heating pipe is better in heating effect and meanwhile energy-saving and environment-friendly. An outer pipe body is formed by connecting a first outer pipe body with a second outer pipe body; the first outer pipe body is provided with a liquid inlet, and the second outer pipe body is provided with a liquid outlet; a heat conduction pipe set is arranged in the second outer pipe body, and is formed by annularly arranging a plurality of heat conduction pipes; a single-head turnup inner pipe body is arranged on the outer portion of the heat conduction pipe set, and a liquid returning flow way is formed between the outer wall of the single-head turnup inner pipe body and the inner wall of the second outer pipe body; heat conduction pieces are arranged on the heat conduction pipe set, and are sleeved in a spacing manner at equal distances; during work, liquid flowing in from the liquid inlet enters the heat conduction pipe set through the liquid inlet end to complete first-time heating, then enters the liquid returning flow way through the liquid outlet end to be heated again, and flows out of the liquid outlet. According to the use effect of thermal efficiency generated by electric heating wires of the same power, the energy-saving effect is greatly improved.
