본 발명은 방열부가 직접 프리히터의 발열부에 접촉되게 함으로써 열전도율을 증대시켜 방열성능을 향상시키고, 한쌍의 방열핀 사이에 고정판을 배치함으로써 조립공수 및 부품수를 절감한 프리히터용 방열부에 관한 것이다.The present invention relates to a preheater heat dissipation unit in which the heat dissipation unit is directly in contact with the heat generating unit of the preheater, thereby increasing heat conductivity to improve heat dissipation performance, and reducing the number of assembly operations and parts by arranging a fixing plate between a pair of heat dissipation fins. .

일반적으로 자동차에는 실내를 난방, 또는 냉방시키기 위한 공기조화장치가 설치되어 통풍계통 및 통풍경로를 통해 자동차 각부분에 냉기 및 난기를 골고루 이송시킨다. Generally, an air conditioner for heating or cooling an interior of a vehicle is installed to evenly transport cold and warm air to each part of the vehicle through a ventilation system and a ventilation path.

즉, 여름철등 실내의 온도를 낮추는 냉방의 경우에는 에어컨을 동작시켜 냉기를 토출시키고, 겨울철등 실내의 온도를 높이는 난방의 경우에는 엔진의 과열 방지를 위해 엔진 내부를 순환하여 가열된 냉각수를 송풍기를 통해 실내로 공급되는 외부공기와 열교환시켜 차량내의 곳곳에 배치된 토출구를 통해 온기를 공급하도록 한다.In other words, in the case of cooling to lower the indoor temperature in summer, the air conditioner is operated to discharge cold air. In the case of heating to increase the indoor temperature in winter, the coolant heated by circulating the inside of the engine is cooled to prevent the engine from overheating. Heat exchange with the outside air supplied into the room through the outlet to be supplied throughout the vehicle to supply the warmth.

그런데, 엔진과 열교환된 냉각수를 이용하여 실내를 난방하는 것이 효율적으로 바람직하기는 하나, 초기 시동 이후에 엔진이 가열되기까지의 시간이 경과해서야 가열된 냉각수를 이용하여 자동차 실내의 난방이 가능해진다. 이때문에, 겨울철 탑승즉시 난방을 하기 위하여 주행전 장시간 엔진을 공회전시키는데, 이로인해 환경오염과 연료과소비 및 차량 소음에 의한 불편함이 있다.However, although it is preferable to efficiently heat the room by using the coolant heat exchanged with the engine, it is possible to heat the interior of the vehicle by using the heated coolant only after a time until the engine is heated after the initial start-up. For this reason, the engine is idling for a long time before driving in order to immediately heat up in winter, thereby causing inconvenience due to environmental pollution, fuel consumption and vehicle noise.

그래서 냉각수의 가열되기 전까지 보조 히터에서 따뜻한 공기를 형성하여 실내로 송풍하는 프리히터에 대한 연구가 활발하게 이루어지고 있는데, 이러한 자동차용 프리히터는 정저항온도계수(正抵抗溫度係數)를 가진 정특성 서미스터(PTC:positive temperature coefficient thermistor, 이하 'PTC소자'라 함)를 사용한 것으로, 화재의 위험이 적고 수명이 길어 반영구적으로 사용할 수 있으며 통전과 동시에 발열되는 반응속도가 빨라 작동즉시 온풍을 공급할 수 있는 장점이 있다.Therefore, studies on preheaters that form warm air in the auxiliary heaters and blow them into the room until the coolant is heated are actively conducted. Such preheaters for automobiles have a positive characteristic with a constant temperature coefficient of temperature. It uses a thermistor (PTC: positive temperature coefficient thermistor, hereinafter referred to as 'PTC element'), and it can be used semi-permanently because it has a low risk of fire and a long lifespan. There is an advantage.

그러나 이러한 종래의 프리히터는 도 1a, 1b에서 도시하는 바와 같이 발열부(10)와 발열부(10) 사이에 배치되는 주름방열핀(20)을 고정하기 위하여 한쌍의 "ㄷ"자형 단면의 안내부재(30)가 주름방열핀(20)의 양측을 감싼 상태에서 상하단이 절곡되어 상,하부몸체(B1,B2)에 고정되는 구조를 갖는다.However, such a conventional preheater is a guide member having a pair of "c" shaped cross-sections to fix the corrugated heat radiation fin 20 disposed between the heat generating portion 10 and the heat generating portion 10, as shown in Figure 1a, 1b. The upper and lower ends are bent in a state in which the 30 wraps both sides of the wrinkled heat radiation fin 20, and has a structure fixed to the upper and lower bodies B1 and B2.

따라서, 발열부(10)로부터 발생된 열은 안내부재(30)를 거친 다음 주름방열판(20)으로 전달되므로 전달과정에서 열손실이 일어날 뿐만 아니라, 외기와 열교환하는 주름방열핀(20)으로 열기가 효과적으로 전달되지 못하여 발열부(10)내에 머무르게 되어 발열부(10)의 발열효율이 떨어지게 되는 문제점이 발생된다.Therefore, the heat generated from the heat generating unit 10 is passed through the guide member 30 and then transferred to the pleat heat sink 20 so that not only heat loss occurs in the transfer process, but heat is also generated by the pleat heat radiation fins 20 that exchange heat with the outside air. There is a problem in that the heat generation efficiency of the heat generating unit 10 is lowered because it is not effectively delivered to stay in the heat generating unit 10.

본 발명은 상기의 문제점을 해결하기 위하여 안출된 것으로 발열부로부터 발생되는 열이 주름방열판으로 직접 전달되게 하여 열전도율을 향상시키는 프리히터용 방열부를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems is to provide a heat dissipation unit for the pre-heater to improve the thermal conductivity by allowing the heat generated from the heat generating portion is transferred directly to the pleated heat sink.

또한, 주름방열판과 발열부의 접촉면에 열전도컴파운드를 도포하여 접촉면의 공극을 메워줌으로써 열전도율을 향상시키고, 발열부내에 열이 머무르지 않도록 하는 프리히터용 방열부를 제공하는데에도 그 목적이 있다.In addition, the purpose of the present invention is to provide a heat dissipation part for the preheater, which improves the thermal conductivity by applying a thermal conductive compound to the contact surface of the wrinkled heat sink and the heat generating part to fill the voids of the contact surface, and prevents heat from remaining in the heat generating part.
