Abstract
A method for making a wave-shaped heating unit and includes a step of preparing a housing by compressing a metal tube to form an elongate tube with an oval cross section; a step of inserting a heating plate by inserting a soft heating plate into the housing, and two respective first ends of two wires connected to the heating plate; a step of clamping by compressing the elongate tube to clamp the heating plate within the housing, two respective second ends of the two wires extending beyond the housing, and a step of forming wave-shape by bending the housing into continuous convex portions and concaved portions.
Claims3
A method for making a wave-shaped heating unit, comprising:
- a step of preparing a housing:
- preparing metal tube and compressing the metal tube so as to form an elongate tube with an oval cross section;
- a step of inserting a heating plate:
- inserting a soft heating plate into the housing, two respective first ends of two wires connected to the heating plate;
- a step of clamping:
- compressing along a short axis of the elongate tube to clamp the heating plate within the housing, two respective second ends of the two wires extending beyond the housing, and
- a step of forming wave-shaped:
- bending the housing to be wave-shaped, bending one end of the housing into a convex portion, a concaved portion being bent and connected to the convex portion, repeating the bending actions to form multiple alternative convex portions and concaved portions.
