PTC HEATER

摘要

A positive temperature coefficient heater includes PTC elements embedded in adjacent heat rods, the PTC elements of the adjacent heat rods include center lines mismatched with each other and configured to minimize regions in which the PTC elements are overlapped with each other in the heat rods in which a plurality of PTC elements spaced apart from each other so as to form columns and rows and arranged in a single layer are embedded.

1. A positive temperature coefficient heater comprising:
a plurality of heat rods each having a plurality of PTC elements embedded therein, each of the plurality of heat rods having a terminal extending outwardly from one side thereof and configured for coupling to an external power source, wherein a center line of each of the plurality of PTC elements embedded in a first one of the plurality of heat rods is mismatched from a center line of each of the plurality of PTC elements of a second one of the plurality of heat rods adjacent the first one of the plurality of heat rods; a plurality of heat radiation fins disposed alternately between the plurality of heat rods; an upper housing coupled to a first end portion of each of the plurality of heat rods; and a lower housing coupled to a second end portion of each of the plurality of heat rods.
