Zusammenfassung:A high effective heat-transfer pipe comprises a main pipe 1 and a sub-pipe 2, wherein the main pipe 1 and the sub-pipe 2 are all metal pipes, the main pipe 1 is sleeved out of the sub-pipe 2, the two ends of the main pipe 1 are all sealed, a low-pressure spacing 10 and nontoxic liquid 11 are sealed in the main pipe 1, a pipe orifice 20 and a pipe orifice 21 are respectively extended out of the two ends of the main pipe 1, the sub-pipe 2 is submerged by the nontoxic liquid 11 when the main pipe 1 is horizontally arranged, and the pressure of the low-pressure spacing 10 is between zero to one atmospheric pressure. The utility model has the advantages of high heat transfer efficiency and small capacity of the heat source system and the like, which can be used as a high effective heat-transfer device for the glasshouse of the agriculture and the forestry, and the heating of a dwelling house and other fields.
