Abstract
A positive temperature coefficient heater may include at least one positive temperature coefficient rod having a heating module inserted into a rod case made of brass and plated with tin, at least one heat-radiating fin made of brass, plated with tin, and contacted and coupled with each of opposite outer faces of the positive temperature coefficient rod, and upper and lower housings coupled to opposite longitudinal ends of the positive temperature coefficient rod, wherein the positive temperature coefficient rod and the heat-radiating fin are joined together by soldered portions.
Claims8
A method of manufacturing a positive temperature coefficient heater, the method comprising:
- plating a rod case of brass with tin;
- plating a heat-radiating fin of brass with tin;
- inserting a heating module into the rod case so as to assemble a positive temperature coefficient rod;
- temporarily coupling the positive temperature coefficient rod with the heat-radiating fin using a separate fixture, and joining the positive temperature coefficient rod and the heat-radiating fin together by means of soldering;
- and
- coupling upper and lower housings to opposite longitudinal ends of the positive temperature coefficient rod and the heat-radiating fin.
