CONDUCTIVE POLYMERIC CONDUIT HEATER

摘要

A heater conduit comprises a hollow tube comprising a conductive polymeric material that exhibits PTC behaviour, and two electrodes positioned in electrical contact with the tube, preferably in a helical configuration. There is preferably an electricably insulating core inside and an outer jacket around the conductive polymeric tube. The conduit can be heated by the passage of electrical current therethrough, and is preferably used to heat a fluid passing through the tube.
