STRUCTURE OF HEATING BODY, AND MANUFACTURING METHOD OF THE SAME

摘要

A structure of a heating body and a method for manufacturing the same are provided to prevent a damage of a heating unit and a tube, and to improve a life span of the heating body by inserting a heating unit into a connection unit or inserting the connection unit into the inside of the heating unit. A structure of a heating body includes a tube(110), and a heating unit(200). The heating unit(200) is arranged inside the tube(110). The inside of the heating unit(200) has a pipe shape. A shape of a cross section of the heating unit(200) corresponds to a shape of a cross section of the tube(110). The cross section of the tube(110) has a hollow shape. The cross section of the heating unit(200) has a hollow shape. The cross section of the heating unit(200) has a totally uniform pipe shape along a length direction. A subsidiary heating unit to have a wider cross section than other area of the heating unit(200) is formed on the heating unit(200).
