Description

차량용 피티씨 히터 장치PTC heater for car

본 발명은 차량용 피티씨 히터 장치에 관한 것으로서, 부품간의 결합성을 개선하고 통기성을 확보하여 방열성능을 향상시키는 차량용 피티씨 히터 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle PTC heater apparatus, and more particularly, to a vehicle PTC heater apparatus which improves heat dissipation performance by improving coupling between components and ensuring ventilation.

일반적으로 차량에는 실내의 각 부위로 냉기와 온기를 선택적으로 공급하기 위한 공조시스템이 구비되는데, 하절기에는 에어컨을 작동시켜 냉기를 공급하고, 동절기에는 히터를 가동하여 온기를 공급하게 된다.In general, the vehicle is provided with an air conditioning system for selectively supplying the cold and warmth to each part of the room, the summer to operate the air conditioner to supply the cold air, the winter to operate the heater to supply the warmth.

히터의 작동 방식은 엔진 내부를 순환하며 가열된 냉각수와 송풍기에 의하여 유입된 공기가 상호 열교환이 이루어지면서 차량 실내로 온기를 공급하며 난방을 하는 방식으로서, 엔진에 의해 발생되는 열을 이용하는 것이므로 에너지 효율이 높은 난방 방식이다.The heater operates in a way that circulates inside the engine and heats the heated coolant and the air introduced by the blower to supply heat to the interior of the vehicle as it heats up, and uses heat generated by the engine. This is a high heating method.

그러나 동절기에는 시동 후 엔진이 가열되기까지 일정 시간이 필요하게 되므로 시동 후 곧바로 난방이 이루어지지 않는다. 따라서 난방을 위하여 엔진이 가열되고 냉각수의 온도가 고온이 될 때까지 주행 전 소정 시간 엔진을 공회전시키게 되는데, 이에 따른 에너지 낭비 및 환경 오염이란 문제가 발생하였다.However, in winter, since the engine needs to be heated for a certain time after starting, heating does not occur immediately after starting. Therefore, the engine is heated for heating and the engine is idled for a predetermined time before driving until the temperature of the coolant becomes high, resulting in energy waste and environmental pollution.

이러한 문제를 방지하기 위해 엔진이 가열되는 소정 시간 동안에 별도의 프리히터(Pre-Heater)를 이용하여 차량 실내를 난방하는 방법이 이용되었는데, 종래의 열선 코일을 이용한 히터는 발열량이 높아 난방은 효과적으로 이루어지나 화재 위험이 높고 전열선의 수명이 짧아 부품의 수리 및 교환이 빈번하게 발생하는 불편이 있었다.In order to prevent such a problem, a method of heating a vehicle interior using a separate pre-heater during a predetermined time during which the engine is heated has been used. A heater using a conventional heating coil has a high heat generation and thus heating is effectively performed. Excessively high risk of fire and short life of electric wires caused frequent repair and replacement of parts.

따라서, 최근에는 피티씨(PTC: Positive Temperature Coefficient)소자를 이용한 히터가 개발되고 있는데, 피티씨 히터는 화재 위험이 적고 수명이 길어 반영구적으로 사용할 수 있는 장점이 있다.Therefore, recently, a heater using a positive temperature coefficient (PTC) device has been developed. The PTC heater has an advantage of being used semi-permanently due to low fire risk and long life.

피티씨 히터는 피티씨 소자와, 피티씨 소자를 감싸고 열을 방출하는 방열판과, 방열판이 장착되는 하우징을 포함한다. 그러나, 피티씨 소자와 이를 감싸는 방열판의 결합력 저하로 인해, 방열이 원활하게 이루어지지 못하는 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.The PTC heater includes a PTC device, a heat sink surrounding the PTC device and dissipates heat, and a housing to which the heat sink is mounted. However, due to the deterioration of the bonding force of the PTC element and the heat sink surrounding it, there is a problem that the heat dissipation is not performed smoothly. Therefore, there is a need for improvement.
