Abstract
A heat rod assembly for preheating internal air of a vehicle by using heat generated from a positive temperature coefficient (PCT) device and a pre-heater for vehicles including the same, in which components of the heat rod assembly and the pre-heater are grouped as module units so that a width and a volume of the heat rod assembly or the pre-heater can be variously formed so that the heat rod assembly or the pre-heater is adaptable for various kinds of vehicles.
Claims11
A heat rod assembly for a pre-heater used in a vehicle, the heat rod assembly comprising:
- a channel type lower heat rod;
- an insulator installed at a bottom portion of the lower heat rod;
- a positive terminal fixedly installed on the insulator lengthwise along the insulator;
- a PTC device coupled to the insulator by interposing the positive terminal therebetween;
- and
- an upper heat rod for covering an opening section of the lower heat rod;
- wherein the insulator is formed with a bottom recess, which extends lengthwise along the insulator in order to receive the positive terminal therein, and wherein the insulator is provided at both longitudinal ends thereof with fixing protrusions, which are inserted into coupling holes formed in the positive terminal.
