| I.P Abstract & Summary |
The present invention relates to a metal heater system. More specifically, the present invention relates to a metal heater system which is characterized in that a plurality of metal heaters is coupled to the surface of the lower end of a pipeline at predetermined intervals in the longitudinal direction of the pipeline and PTC heating elements inside the metal heaters conduct heat to local portions of the pipeline. Due to these characteristics, convection is generated in a fluid inside the pipeline because of the heat conducted to the local portions and thus the overall pipeline is maintained at a constant temperature, thereby efficiently preventing the freezing and bursting of the pipeline in winter. |
