Heater for vehicles

摘要

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.

主权项

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.
