Abstract
Disclosed herein is a PTC heater for a vehicle, which includes a plurality of cores, such as a first core and a second core, disposed independently and respectively arranged in a first passageway and a second passageway of an air-conditioning case to be controlled independently, thereby reducing manufacturing costs and weight of the air conditioner, enhancing vehicle fuel efficiency and productivity, being easily applicable to other vehicles using PTC heaters because one PTC heater is used for independent control at the right and the left.
Claims8
A positive temperature coefficient (PTC) heater for a vehicle, which is inserted and mounted in a plurality of passageways formed inside an air-conditioning case to heat air flowing in the passageways, the PTC heater comprising:
- a housing inserted and mounted across the passageways of the air-conditioning case;
- and
- a core part formed by a plurality of cores respectively arranged on the passageways inside the housing,
- wherein the PTC heater independently controls the cores arranged on the passageways to independently heat airs respectively flowing in the passageways,
- wherein the passageways are formed with a first passageway and a second passageway which are formed inside the air-conditioning case, and wherein the cores are formed with a firs core arranged on the first passageway and a second core arranged on the second passageway,
- wherein a heat protection member for preventing heat transfer between the first core and the second core is mounted between the first core and the second core,
- wherein the heat protection member includes at least one bypass hole to make some of the air passing through the PTC heater bypass the first core and the second core.
