Abstract

Provided is a heater for a motor vehicle including: a heat source part: a heat source part rod including a rod sidewall and a rod cover in order to receive the heat source part; a first heat radiating plate including a first heat generation region in which one side of the heat source part is disposed and a first air movement region in which at least one or more first through-holes are formed; and a second heat radiating plate including a second heat generation region in which the other side of the heat source part is disposed and a second air movement region in which at least one or more second through-holes are formed. Particularly, the heat source part is disposed between the first and second heat radiating plates, and the rod sidewall is provided integrally with the first heat radiating plate.

First claim

The invention claimed is:

1. A heater for a motor vehicle comprising:
a heat source part;
a heat source part rod including a rod sidewall and a rod cover which receives the heat source part;
a first heat radiating plate including a first heat generation region and a first air movement region, the first air movement region having at least one first air through-hole, which has a slit-shape with a line direction, formed therein, the heat source part disposed on a first side of the first heat radiating plate, and the rod sidewall formed integrally with the first heat radiating plate; and
a second heat radiating plate including a second heat generation region and a second air movement region, the second air movement region having at least one second air through-hole formed therein,
wherein the heat source part is disposed between the first heat radiating plate and the second heat radiating plate, and
wherein the second air through-hole, which has a slit shape with a line direction, is disposed so that the line direction of the second air through-hole intersects the line direction of the first air through-hole when viewed in a direction of air movement,
wherein the heat source part includes a positive temperature coefficient device, an electrode plate electrically contacting the positive temperature coefficient device, and an insulating guide member insulating the positive temperature coefficient device and the electrode plate from the rod sidewall,
wherein the insulating guide member is formed in a tube shape with a slit-shaped electrode plate receiver into which the electrode plate is inserted, the slit-shaped electrode plate receiver is a hollow inner space of the insulating guide member, and
wherein the insulating guide member has an opening part penetrating through surfaces of the tube shape, wherein the slit-shaped electrode plate receiver communicates with the opening part, and the positive temperature coefficient device is inserted into the opening part, wherein the positive temperature coefficient device is electrically contacting the electrode plate.

2. The heater for a motor vehicle of claim 1 , wherein the rod sidewall is extrusion-molded integrally with the first heat radiating plate.

3. The heater for a motor vehicle of claim 1 , wherein the positive temperature coefficient device and the electrode plate are sequentially stacked in an axial direction, and wherein the first heat radiating plate, the heat source part, and the second heat radiating plate are coupled to each other in the axial direction.

4. The heater for a motor vehicle of claim 3 , wherein the rod cover includes a first rod cover provided with step parts and the rod sidewall includes a pair of sidewalls spaced apart from each other by a predetermined distance, wherein a catching jaw is formed at an upper end portion of each of the sidewalls, wherein the step parts of the rod cover are seated on the catching jaw, and wherein modified parts extend from the catching jaws and are pressed to upper surfaces of the step parts.

5. The heater for a motor vehicle of claim 4 , wherein the rod cover and the second heat radiating plate are coupled to each other by an adhesive.
