PURPOSE: A heat transmission cylinder with a U-shaped core pipe and a loop pipe is provided to prevent energy loss by using a U-shaped core pipe as a heat insulating material. CONSTITUTION: A heat transmission cylinder with a U-shaped core pipe and a loop pipe comprises a U-shaped pipe, a columnar heat transfer body(300), and a heat insulating unit(400). Heat transfer fluid passes through the U-shaped pipe. The U-shaped pipe is installed in the columnar heat transfer body. The columnar heat transfer body is composed of a thermal conductive material. The heat insulating unit is located to be closed to the axial core part of the columnar heat transfer body and remarkably reduce energy loss. |
