HEATED HOSE AND METHOD

摘要

A heated hose assembly (10) includes a tubular member (12), a heater device (14) having an electrical resistance element (18) in thermal communication with the tubular member (12), and a thermal regulating device (30) that controls a flow of electrical current through the heater device (14) based on a sensed temperature of the hose assembly (10). Heat generated by the heater device (14) when the electrical current flows through the resistance element (18) heats the tubular member (12) to prevent or minimize condensation of gases, or coagulation or freezing of liquids, within the tubular member (12) at relatively low ambient temperatures. A method for controlling a heated hose assembly (10) includes providing the referenced tubular member (12), heater device (14), and thermal regulating device (30), and controlling a flow of current through the heater device (14) based on a sensed hose assembly temperature, wherein heat generated by the heater device (14) when the electrical current flows through the heater device (14) heats the tubular member (12).
