Abstract

A heater apparatus for a vehicle may include a main heater of a vehicle, and an auxiliary heater coupled with the main heater at the rear side thereof and having a housing including an edge part and an inner part, wherein heat radiation fins and positive temperature coefficient (PTC) element assemblies are coupled with the housing at the front surface thereof.

First claim

What is claimed is:

1. A heater apparatus for a vehicle, comprising:
a main heater of the vehicle; and
an auxiliary heater coupled with the main heater at a rear side thereof and having a housing including an edge part and an inner part, wherein heat radiation fins and positive temperature coefficient (PTC) element assemblies are coupled with the housing at a front surface thereof, and
wherein a tube pitch formed by the heat radiation fins of the auxiliary heater and the PTC element assemblies is equal to or less than a tube pitch of the heat radiation fins of the main heater.

2. The heater apparatus according to claim 1 , wherein the main heater and the auxiliary heater are integrally coupled with each other with a predetermined distance therebetween.

3. The heater apparatus according to claim 1 , wherein the inner part of the housing of the auxiliary heater has the same area with an area of a core of the main heater.

4. The heater apparatus according to claim 1 , wherein at both sides of the edge part of the auxiliary heater, bar-like, side-supporting parts are formed in a vertical direction from the edge part toward the inner part, and wherein on a rear surface of the side-supporting parts, heat radiation fins are formed in the vertical direction.

5. The heater apparatus according to claim 1 , wherein at both sides of the edge part of the auxiliary heater, bar-like, side-supporting parts are formed in a vertical direction from the edge part toward the inner part, and wherein on a rear surface of the side-supporting parts, the PTC element assemblies are formed in the vertical direction.

6. The heater apparatus according to claim 1 , wherein at both sides of the edge part of the auxiliary heater, bar-like, side-supporting parts are formed in a vertical direction from the edge part toward the inner part, and wherein on a rear surface of the side-supporting parts, the heat radiation fins and the PTC element assemblies are formed in the vertical direction, wherein the heat radiation fins and the PTC element assemblies are disposed discretely.

7. The heater apparatus according to claim 1 , wherein an entire inner part of the housing is penetrated so as to have a penetration hole therein.

8. The heater apparatus according to claim 7 , wherein at a center of the penetration hole, a bar-like, center-supporting part is formed extending from an upper end to a lower end of the penetration hole, and wherein on a rear surface of the center-supporting part, the heat radiation fins and the PTC element assemblies are formed in the vertical direction, wherein the heat radiation fins and the PTC element assemblies are disposed discretely.

9. The heater apparatus according to claim 1 , wherein the heat radiation fins of the auxiliary heater are corrugated in a height direction thereof.

10. The heater apparatus according to claim 1 , wherein the heat radiation fins of the auxiliary heater are inclined by a predetermined angle so as to form a louver shape.

11. The heater apparatus according to claim 1 , wherein the edge part of the housing of the auxiliary heater is extended toward a front of the auxiliary heater, and wherein coupling parts surrounding an inlet and an outlet of the main heater are formed at side ends of the auxiliary heater so that the auxiliary heater and the main heater are coupled by fitting.

12. The heater apparatus according to claim 1 , wherein the edge part of the housing of the auxiliary heater is extended toward a front of the auxiliary heater, wherein a recess groove is formed in an inner side of a side surface of the extended housing, and wherein a blade of a side plate of the main heater fits in the recess groove such that a distance between the main heater and the auxiliary heater is adjustable.

13. The heater apparatus according to claim 1 , wherein a height formed by the heat radiation fins of the auxiliary heater and the PTC element assemblies is equal to a height formed by the heat radiation fins of the main heater and a tube.

14. The heater apparatus according to claim 1 , wherein the heat radiation fins of the auxiliary heater are formed in the same direction in which the heat radiation fins of the main heater are formed.

15. The heater apparatus according to claim 1 , further comprising a power terminal formed on a side surface of the housing of the auxiliary heater so as to supply power, wherein the power terminal is vertically formed in the same direction as that to which a pipe of the main heater is connected.

16. The heater apparatus according to claim 15 , wherein the power terminal of the auxiliary heater is arranged in the housing of the auxiliary heater in a stepwise manner.

17. A heater apparatus for a vehicle, comprising:
a main heater of the vehicle; and
an auxiliary heater coupled with the main heater at a rear side thereof and having a housing including an edge part and an inner part, wherein heat radiation fins and positive temperature coefficient (PTC) element assemblies are coupled with the housing at a front surface thereof,
wherein at both sides of the edge part of the auxiliary heater, bar-like, side-supporting parts are formed in a vertical direction from the edge part toward the inner part, and wherein on a rear surface of the side-supporting parts, the PTC element assemblies are formed in the vertical direction.

18. A heater apparatus for a vehicle, comprising:
a main heater of the vehicle; and
an auxiliary heater coupled with the main heater at a rear side thereof and having a housing including an edge part and an inner part, wherein heat radiation fins and positive temperature coefficient (PTC) element assemblies are coupled with the housing at a front surface thereof,
wherein at both sides of the edge part of the auxiliary heater, bar-like, side-supporting parts are formed in a vertical direction from the edge part toward the inner part, and wherein on a rear surface of the side-supporting parts, the heat radiation fins and the PTC element assemblies are formed in the vertical direction, wherein the heat radiation fins and the PTC element assemblies are disposed discretely.
