Abstract:
1. A heating apparatus comprising: a heating chamber having a flow channel through which fluid flows, the heating chamber comprising a chamber body having a groove and a chamber cover coupled to one side of the chamber body; a heat transfer part mounted between the chamber body and the chamber cover, the heat transfer part having one side facing the chamber body and other side facing the chamber cover; two electrodes connected to both sides of the heat transfer part; a plurality of carbon nanotube heating elements that are disposed apart from each other on the other side of the heat transfer part and generate heat by power applied through the electrodes; a bracket coupled to the heat transfer part; at least one bimetal mounted on the bracket to selectively apply power to the carbon nanotube heating elements, in accordance with the temperature of the heat transfer part; an insulating member provided at the other side of the heat transfer part to insulate the electrodes and the carbon nanotube heating elements; and a sealing member mounted between an edge of the chamber body and the chamber cover to prevent the fluid flowing through the flow channel from leaking, wherein the flow channel is defined by the groove of the chamber body and the one side of the heat transfer part, fluid flowing through the flow channel being contacted with a surface of the one side of the heat transfer part.
