POWER CONTROLLED HEATING SYSTEM

摘要

A method for heating an object, where the method includes the steps of choosing one or more elongated heating member or members, adapting one or more elongated heating member or members to form an elongated combined heating member having a length within a predetermined length interval and providing a predetermined constant current through the elongated combined heating member by connecting a constant current source to a first end and a second end of the elongated combined heating member, such that the combined heating member generating a power per unit length when the constant current flowing through the combined heating member between the first end and the second end. A device for heating an object and a kit of parts for assembling such a heating device is also disclosed.

1. A method for heating an object, said method comprising the steps of:
choosing one or more elongated heating member or members, said one or more heating member or members having a predetermined resistance per unit length; adapting said one or more elongated heating member or members to form an elongated combined heating member having a length within a predetermined length interval, wherein said predetermined length interval is dependent upon the choice of the one or more elongated heating member or members; and providing a predetermined constant current through said elongated combined heating member by connecting a means for generating a constant current to a first end and a second end of said elongated combined heating member, such that said combined heating member generating a power per unit length when said constant current flowing through said combined heating member between said first end and said second end; wherein said one or more elongated heating member or members having said predetermined resistance per unit length is or are chosen such that a voltage required for maintaining said predetermined constant current is within a predetermined voltage interval for every possible length of said combined heating member within said predetermined length interval.
