Description

자동차용 난방기Car radiators

본 고안은 PTC(Positive Temperature Coefficient)소자를 이용한 자동차용 난방기에 관한 것이다.The present invention relates to a car heater using a PTC (Positive Temperature Coefficient) element.

일반적으로 자동차의 내부에는, 차실내의 난방이나 차량전면 유리의 제습 또는 성에제거를 위해 엔진에서 발생하는 열에 의해 데워진 냉각수의 열에너지를 이용하여 차량을 난방하는 난방기가 배설되어 있다.In general, a heater is installed inside a vehicle to heat the vehicle by using heat energy of cooling water warmed by heat generated by the engine for heating the vehicle interior, dehumidifying the front glass of the vehicle, or defrosting.

이러한 난방기는, 엔진이 가동된 후 엔진의 주위를 흐르는 냉각수가 데워져 난방기에 유입하므로, 엔진을 가동하고 난 후에도 실내가 난방되기까지는 장시간이 소요된다. 따라서, 추운 겨울에는 운전자나 승객이 엔진을 가동한 후 한동안 추운 상태로 지내야 한다는 문제점이 있었다.Since such a heater warms up the coolant flowing around the engine after the engine is started and flows into the heater, it takes a long time for the room to be heated even after the engine is operated. Therefore, in the cold winter, there is a problem that a driver or a passenger has to stay cold for a while after operating the engine.

또한, 전기 자동차에 있어서는 상기한 바와 같은 엔진냉각수가 없으므로 난방열원이 없어다.In addition, in the electric vehicle, there is no heating heat source because there is no engine cooling water as described above.

이러한 문제점을 해결함과 동시에 전기 자동차의 난방용으로 PTC(Positive Temperature Coefficient)소자를 이용한 난방기가 개발되어 있다.At the same time, a heater using a PTC (Positive Temperature Coefficient) device has been developed for heating electric vehicles.

그런데, 종래 PTC소자를 이용한 난방기는 소비전력이 크고 전기단락의 위험이 크므로 안전성이 낮아, 특히 자동차에서는 실용적으로 사용되지 못하고 있다는 문제점이 있었다.However, the conventional heater using the PTC element has a low power consumption because of the large power consumption and the risk of electric short, there is a problem in that it is not practically used in the automobile in particular.

따라서, 본 고안은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 고안의 목적은 차내의 온도조절을 용이하게 하여 전력소비를 줄이고, 전기단락의 위험을 없애어 안전성을 높인 자동차용 난방기를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a heater for a car heater that improves safety by facilitating temperature control in a vehicle to reduce power consumption and eliminate the risk of an electric short circuit. .

They are arranged in parallel, and a plurality of heat dissipation fins are disposed between each of the short-circuit-receiving receiving plates to facilitate heat exchange, and one terminal (eg, -terminal) of each PCT element is combined into one and connected to a power source. The other terminal (for example, + terminal) is characterized in that connected to the power supply via a switch that operates independently of each other.

또한, 상기 단락방지용 수용판과 상기 방열핀사이에는 플레이트가 배설되고, PTC소자가 이물질의 부착에 의해 서로 단락하지 않도록 상기 단락 방지용 수용판의 높이는 방열핀 및 플레이트의 높이보다 높게 되어 있는 것을 특징으로 한다.In addition, a plate is disposed between the short circuit preventing receiving plate and the heat dissipation fin, and the height of the short circuit preventing accommodating plate is higher than the height of the heat dissipation fin and the plate so that the PTC element is not shorted to each other by adhesion of foreign matter.

이하, 본 고안의 일실시예에 관하여 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제1도 내지 제3도에 도시한 바와 같이, 프레임(11)의 내부에는 PTC소자(20)의 단락을 방지하도록 다수의 단락방지용 수용판(13)이 병렬로 배설되어 있고, 상기 각 단락방지용 수용판(13)사이에는 열교환이 용이하도록 다수의 방열핀(15)이 배설되어 있다. 그리고, 상기 방열핀(15)은 그 높이와 동일한 높이의 플레이트(17,18)를 사이에 두고 상기 PTC소자(20)에 접하게 배설되어 있다.1 to 3, inside the frame 11, a plurality of short circuit preventing receiving plates 13 are disposed in parallel to prevent a short circuit of the PTC element 20. A plurality of heat dissipation fins 15 are disposed between the receiving plates 13 to facilitate heat exchange. The heat dissipation fins 15 are disposed in contact with the PTC element 20 with the plates 17 and 18 having the same height therebetween.

상기 단락방지용 수용판(13)의 제 4도에 도시한 바와 같이, 일정한 직사각판형상으로서, 그 면에는 PTC소자(20)를 수용하도록 다수의 관통구멍(13a)이 일렬로 형성되어 있다.As shown in FIG. 4 of the short-circuit-prevention receiving plate 13, a plurality of through-holes 13a are formed in a row in a shape of a constant rectangular plate in which the PTC element 20 is accommodated.

상기 단락방지용 수용판(13)은 상기 방열핀(15)과 플레이트(17,18)의 높이보다 높게 되어 있다.The short circuit preventing receiving plate 13 is higher than the height of the heat dissipation fin 15 and the plates 17 and 18.

이때 상기 관통구멍(13a)은 사각형으로 되어 있으나, PTC소자의 형상에 따라 원형등 다양한 형상으로 될 수 있다.At this time, the through hole 13a is rectangular, but may be in various shapes such as a circle according to the shape of the PTC element.

상기 플레이트(17)의 일단은 상기 단자판(19)에 접속되어 상기 프레임(11)과 함께 하나의 -단자를 형성하고 있고, 상기 플레이트(18)의 일단은 도시하지 않은 전선에 연결되는 각각의 +단자를 형성하고 있다.One end of the plate 17 is connected to the terminal plate 19 to form a single terminal together with the frame 11, and one end of the plate 18 is connected to an electric wire (not shown). It forms a terminal.

상기 PTC소자(20)는 티탄산바륨을 기본조성으로 하는 공지의 산화물 반도체 세라믹소자로서, 그 양측면에는 -전원에 연결되는 플레이트(17) 및 +전원에 연결되는 플레이트(18)가 각각 밀착/접촉되어 있다.The PTC element 20 is a well-known oxide semiconductor ceramic element based on barium titanate. On both sides thereof, a plate 17 connected to a -power source and a plate 18 connected to a + power source are brought into close contact with each other. have.

제5도에 도시한 바와 같이, 상기 각 PTC소자(20)의 (-)단자는 상기 단자판(19) 및 프레임(11)을 통해 하나의 단자로 되어 전원에 연결되어 있고, 상기 각 PTC소자(20)의 (+)단자는 각각 개별로 작동하는 스위치(31)를 매개로 전원에 연결되어 있다.As shown in FIG. 5, the (-) terminal of each PTC element 20 is connected to a power supply as one terminal through the terminal plate 19 and the frame 11, and each PTC element ( The positive terminal of 20) is connected to a power source via a switch 31 which operates individually.

그리고, 상기 각 스위치(31)의 일측에는 콘트롤러(33)의 제어에 의해 상기 각 스위치(31)를 개페하는 릴레이(35)가 배설되어 있다.On one side of each switch 31, a relay 35 is provided to open and close each switch 31 under the control of the controller 33.

또한, 상기 콘트롤러(33)내에는 초기돌입전류를 효과적으로 제한하도록 타이머(37)가 설치되어 있다.In addition, a timer 37 is provided in the controller 33 to effectively limit the initial inrush current.

이와 같이 구성된 자동차용 난방기에서, 전원이 인가되고 타이머(37)에 의해 일정시간간격을 유지하며 콘트롤러(33)의 제어에 의해 릴레이(35)가 작동하면, 상기 릴레이(35)에 인접한 스위치(31)가 닫히게 되어 PTC소자(20가 발열하여, 그 열은 플레이트(17, 18)를 통해 방열핀(15)에 전단/방열되어 주위의 온도를 높이게 된다.In the automobile heater configured as described above, when the power is applied and the interval is maintained by the timer 37 and the relay 35 is operated by the control of the controller 33, the switch 31 adjacent to the relay 35 is activated. ) Is closed so that the PTC element 20 generates heat, and the heat is sheared / heated to the heat dissipation fin 15 through the plates 17 and 18 to increase the ambient temperature.

이때 도시하지 않은 팬으로 방열효과를 높이게 된다.At this time, the heat dissipation effect is increased by a fan (not shown).

한편, 상기 콘트롤러(33)의 제어에 의해 일정한 위치에 있는 일정한 수의 릴레이만 작동시키면, 그 릴레이와 작용하는 스위치만 닫히게 되어 일정한 위치에 일정한 수만의 PTC소자만 방열하므로, 방열량을 조절함과 동시에 방열위치를 조절할 수 있다.On the other hand, if only a certain number of relays at a certain position are operated by the control of the controller 33, only a switch acting on the relay is closed, so that only a certain number of PTC elements are radiated at a predetermined position, thereby controlling the amount of heat dissipation. The heat dissipation position can be adjusted.

본 고안에 의한 자동차용 난방기는 단락방지용 수용판이 방열핀 및 플레이트의 높이보다 높게 되어 있으므로, 이물질의 부착에 의해 인접하는 PTC소자가 서로 단락하는 형상을 방지할 수 있다.In the automobile heater according to the present invention, since the accommodating plate for preventing short circuit is higher than the height of the heat radiation fin and the plate, it is possible to prevent a shape in which adjacent PTC elements are short-circuited by the attachment of foreign matter.

또한, 플레이트에 의해 일측단자(-단자)는 모두 프레임에 접속되어 하나로 되어 있으므로, 전선이 절감되고 배선이 간단해 진다.In addition, since one side terminal (-terminal) is all connected to the frame by the plate and becomes one, the electric wire is reduced and wiring is simplified.

또한, 일정한 위치에 일정한 수만의 PTC소자를 작동하여 난방기의 방열량을 조절함과 동시에 방열위치를 조절할 수 있으므로, 외기 열부하 조건 및 승차자의 요구 실내온도에 맞게 온도 및 소비전력을 효율적으로 제어 할 수 있다.In addition, by operating several tens of thousands of PTC elements at a certain position, it is possible to control the amount of heat dissipation of the heater and the heat dissipation position at the same time, so that the temperature and power consumption can be efficiently controlled according to the external heat load condition and the passenger's required room temperature. .
