Claims

[Scope of Claim for Utility Model Registration] (1) A thermally conductive member with good thermal conductivity that incorporates a heating element is coated with a heat insulating material on the outside to constitute a two-layer antifreeze cover, and The cover is divided into two parts and formed into a cylindrical shape that can be opened and closed, and the anti-freeze cover is wrapped around the outer circumferential surface of the conduit exposed to the outside air, and the heat generating element generates heat to cause the conduit to be heated from the outer circumferential surface. A heater for preventing freezing of exposed pipes, characterized by heating the pipes to prevent freezing of the pipes. (2) A heater for preventing freezing of an exposed pipe line, characterized in that a flexible packing is interposed at the opening/closing part of the freeze-prevention cover and/or at the upper and lower ends in contact with the outer peripheral surface of the pipe line.
