Abstract
A heater includes a heating element, a first electrode, a second electrode and a temperature controller. The heating element includes carbon nanotube layer and a binder. The carbon nanotube layer defines a number of wrinkles. The temperature controller is electrically connected to the heating element by the first electrode or the second electrode. The temperature controller is capable of controlling a temperature of the heating element by controlling a voltage and electric current applied to the heating element.
Claims18
A heater comprising:
- a heating element having a negative temperature coefficient κ and comprising a carbon nanotube layer and a binder layer attached directly to the carbon nanotube layer, the carbon nanotube layer defining a plurality of wrinkles;
- a first electrode and a second electrode located on two ends of the carbon nanotube layer;
- and
- a temperature controller electrically connected to the heating element via the first electrode or the second electrode;
- wherein the temperature controller controls a temperature of the heating element by controlling a voltage and an electric current applied to the heating element;
- the temperature of the heating element satisfies a formula:
- T=(U/I−A)/κ, wherein T is the temperature of the heating element, U is voltage, I is the electric current, and A is a constant.
