Title:
FLOOR-HEATING PIPE HAVING ELECTRICAL WIRE ELECTRODES COMPOUNDED ON INNER WALL OF PLASTIC PIPE
Document Type and Number:
WIPO Patent Application WO/2021/004001
Kind Code:
A1
Abstract:
A floor-heating pipe having electrical wire electrodes (2) compounded on the inner wall of a plastic pipe (1), comprising the plastic pipe (1), and the electrical wire electrodes (2) on the pipe wall, wherein two electrical wire electrodes (2) are mutually electrically insulated and symmetrically arranged on the diameter of the inner wall of the plastic pipe (1) in parallel straight lines or in a parallel winding mode. Water formed between the two electrical wire electrodes (2) at the inner wall of the pipe is electrically connected in parallel to the two electrical wire electrodes (2) to constitute an electrical circuit in which the electrical wire electrodes (2) generate heat by means of water resistance. Safe electric heating of the electrically heated floor-heating pipe is achieved by directly powering the two electrical wire electrodes (2) compounded on the inner wall of the plastic pipe, and utilizing the inherent resistance of water between the two electrical wire electrodes (2) inside the plastic pipe (1) to generate heat. Further disclosed is a fabrication method for the floor-heating pipe having the electrical wire electrodes (2) compounded on the inner wall of the plastic pipe (1).
