Abstract

Provided is a heater for vehicles, and more particularly, to a heater for vehicles, in which a first heater heated by a flowing of engine cooling water and a second heater heated by a power supply are integrally assembled, thereby increasing spatial efficiency and more increasing heat exchange performance to improve heating performance.

First claim

What is claimed is:

1. A heater for vehicles, comprising:
a first heater which includes a first header tank and a second header tank spaced apart from each other by a predetermined distance, an inlet pipe and an outlet pipe which are respectively, alternately disposed at the first header tank and the second header tank to have cooling water introduced and discharged thereinto and therefrom, and a plurality of tubes disposed between the first and second header tanks and fixed to the first and second header tanks, a plurality of cooling water passages defined by the first, second header tanks and the plurality of tubes, and fins disposed between the plurality of tubes; and
a second heater which includes a first support part having a plate shape perpendicular to an air flow direction and including a first heat radiating region and a first air flow region having a plurality of first holes, a heat radiating unit fixed to the first heat radiating region of the first support part to radiate heat, and a housing coupled to the first support part and one end of the heat radiating unit,
wherein the first support part of the second heater is disposed adjacent to the plurality of tubes and the fins of the first heater, and
wherein the heat radiating part includes:
a heat radiating tube that is coupled with the first heat radiating region of the first support part;
an insulating support which is disposed in the heat radiating tube and includes a space part;
a positive temperature coefficient (PTC) element which is disposed in the space part of the insulating support; and
an electrode which is disposed in the insulating support.

2. The heater for vehicles of claim 1 , further comprising:
a first side plate including a plate-shaped first plate part attached to one end of the first and second header tanks, respectively and a second side plate including a plate-shaped second plate part attached to another end of the first and second header tanks, respectively.

3. The heater for vehicles of claim 2 , wherein the first side plate includes two protruded longitudinal portions respectively protruding from both longitudinal edges of the first plate part.

4. The heater for vehicles of claim 3 , wherein one of the protruded longitudinal portions includes a first fastening part,
the housing includes a second fastening part disposed to correspond to the first fastening part, and
the first fastening part and the second fastening part are fastened with a fastener to fix the first heater and the second heater.

5. The heater for vehicles of claim 3 , wherein the housing includes a fixed part fastened with one of the protruded longitudinal portions of the first side plate.

6. The heater for vehicles of claim 2 , wherein the second side plate includes two protruded longitudinal portions protruding from both longitudinal edges of the second plate part.

7. The heater for vehicles of claim 2 , wherein the second side plate extends to the second heater side to support one side of the second heater.

8. A heater for vehicles, comprising:
a first heater which includes a first header tank and a second header tank spaced apart from each other by a predetermined distance, an inlet pipe and an outlet pipe which are respectively, alternately disposed at the first header tank and the second header tank to have cooling water introduced and discharged thereinto and therefrom, and a plurality of tubes disposed between the first and second header tanks and fixed to the first and second header tanks, a plurality of cooling water passages defined by the first, second header tanks and the plurality of tubes, and fins disposed between the plurality of tubes; and
a second heater which includes a first support part having a plate shape perpendicular to an air flow direction and including a first heat radiating region and a first air flow region having a plurality of first holes, a heat radiating unit fixed to the first heat radiating region of the first support part to radiate heat, and a housing coupled to the first support part and one end of the heat radiating unit,
wherein the first support part of the second heater is disposed adjacent to the plurality of tubes and the fins of the first heater, and
wherein the second heater includes upper and lower ends and includes a third fixed hook fixed to an outer circumferential surface of the first header tank or the second header tank.

9. A heater for vehicles, comprising:
a first heater which includes a first header tank and a second header tank spaced apart from each other by a predetermined distance, an inlet pipe and an outlet pipe which are respectively, alternately disposed at the first header tank and the second header tank to have cooling water introduced and discharged thereinto and therefrom, and a plurality of tubes disposed between the first and second header tanks and fixed to the first and second header tanks, a plurality of cooling water passages defined by the first, second header tanks and the plurality of tubes, and fins disposed between the plurality of tubes; and
a second heater which includes a first support part having a plate shape perpendicular to an air flow direction and including a first heat radiating region and a first air flow region having a plurality of first holes, a heat radiating unit fixed to the first heat radiating region of the first support part to radiate heat, and a housing coupled to the first support part and one end of the heat radiating unit,
wherein the first support part of the second heater is disposed adjacent to the plurality of tubes and the fins of the first heater, and
wherein the second heater includes a fourth fixed hook fixed to the inlet pipe or the outlet pipe of the first heater and enclose a portion of the inlet pipe or the outlet pipe of the first heater.

10. A heater for vehicles, comprising:
a first heater which includes a first header tank and a second header tank spaced apart from each other by a predetermined distance, an inlet pipe and an outlet pipe which are respectively, alternately disposed at the first header tank and the second header tank to have cooling water introduced and discharged thereinto and therefrom, and a plurality of tubes disposed between the first and second header tanks and fixed to the first and second header tanks, a plurality of cooling water passages defined by the first, second header tanks and the plurality of tubes, and fins disposed between the plurality of tubes;
a second heater which includes a first support part having a plate shape perpendicular to an air flow direction and including a first heat radiating region and a first air flow region having a plurality of first holes, a heat radiating unit fixed to the first heat radiating region of the first support part to radiate heat, and a housing coupled to the first support part and one end of the heat radiating unit; and
