Heating element and a production method thereof

摘要

The present invention relates to a heating element comprising: two or more heating units comprising two busbars and a conductive heating means electrically connected to the two busbars, in which the busbars of the heating units are connected with each other in series and power per unit area of each of the heating units in the heating element decreases as a length of the busbar increases, and a method of preparing the same.

主权项

1. A heating element, comprising:
two or more heating units, each heating unit comprising:
two busbars; anda conductive heating means electrically connected to the two busbars and positioned between the busbars, thereby separating the busbars by a gap, wherein the busbars of the respective heating units are connected in series, wherein the power per unit area of each heating unit is determined by length of the respective busbars and does not correlate with the gap between the busbars of the respective heating unit.
