본 발명은 차량의 히터 코어에 관한 것으로서, 특히 차량의 히터 코어와 전기 발열 소자를 일체로 형성하고, 히터 코어에 냉각수 순환로를 형성함으로써 차량 엔진의 동작 초기에도 적절한 난방 효과를 얻음과 동시에 냉각수를 가열할 수 있고 전체적인 부피의 축소와 중량의 감소 효과를 얻을 수 있도록 하는 차량의 히터 코어에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater core of a vehicle. In particular, the heater core of the vehicle and the electric heating element are integrally formed, and a coolant circulation path is formed in the heater core to obtain a proper heating effect even at the initial stage of operation of the vehicle engine, and to heat the coolant. The present invention relates to a heater core of a vehicle which can achieve the effect of reducing the overall volume and reducing the weight.

일반적으로 차량의 내부에는 난방을 목적으로 하는 난방장치가 구비되어 있 고, 이때 주로 사용하는 난방장치는 엔진의 가열된 냉각수를 순환시켜 실내 유입공기와 열교환하는 히터 코어가 사용되고 있다.In general, a heating device for heating purposes is provided in the interior of a vehicle. In this case, a heater core mainly used is a heater core that circulates heated coolant of an engine to exchange heat with indoor inlet air.

그러나 상기와 같은 종래의 히터 코어는 차량 엔진의 열이 일정 수준 이상 상승되어야만 냉각수의 온도가 올라가고, 온도가 올라간 냉각수가 상기 히터 코어 속으로 순환할 때 비로소 적당한 열교환이 이루어지기 때문에 늦게 난방이 시작되는 것이다.However, in the conventional heater core as described above, when the heat of the vehicle engine is raised above a certain level, the temperature of the coolant is increased, and since the proper heat exchange is performed when the coolant with the temperature is circulated into the heater core, heating is started late. will be.

즉, 엔진이 구동되고 일정 시간이 흘러 냉각수 온도가 높아져야만 실내 난방이 가능하기 때문에 시동 초기 난방이 어려운 문제점이 있었다. That is, since the engine is driven and a certain amount of time passes and the cooling water temperature is increased, indoor heating is possible.

상기와 같은 종래의 문제점을 해결하기 위해 차량의 공조시스템에 전기발열소자(PTC)를 열원으로 하는 별도의 보조히터를 내장하여 공기를 직접 가열하거나, 차량의 엔진 냉각수를 직접 가열하는 방식과 같이 PTC 소자와 같은 전기발열소자를 사용하는 초기난방장치가 개시되었다. In order to solve the above-mentioned problems, PTC is built in a method of directly heating air or directly heating engine coolant in a vehicle by embedding a separate auxiliary heater using a heat generating element (PTC) as a heat source in the vehicle air conditioning system. An initial heating device using an electric heating element such as an element has been disclosed.

공조시스템에 전기 발열소자(PTC)를 추가하여 공기를 직접가열하는 방식은 공조 시스템내에서 공기 저항을 발생시키고, 엔진 냉각수를 이용하는 히터 코어와 별도의 유니트를 구비해야 하기 때문에 장치의 설치 장소가 넓어지고 무게가 증가되는 문제점이 있었다. The method of directly heating air by adding an electric heating element (PTC) to the air conditioning system generates air resistance in the air conditioning system, and requires a separate unit from the heater core using engine coolant. There was a problem of losing weight and increasing weight.

본 발명은 이와 같은 종래의 제반 문제점을 해결하기 위한 것으로서, 차량의 히터 코어와 전기 발열 소자를 일체화 형성하여 차량 엔진의 동작 초기에 난방 효과를 얻을 수 있고 전체적인 부피의 축소와 중량의 감소 효과를 얻을 수 있도록 하는 차량의 히터 코어를 제공하는 것을 목적으로 한다.
또한, 히터 코어에 냉각수 순환로를 일체로 구성함으로써 공기 가열과 동시에 냉각수도 가열하여 엔진의 예열 시간을 단축시킬 수 있는 차량의 히터 코어를 제공하는 것을 목적으로 한다.The present invention is to solve the above-mentioned conventional problems, by integrally forming the heater core and the electric heating element of the vehicle to obtain the heating effect at the beginning of the operation of the vehicle engine and to reduce the overall volume and weight reduction effect It is an object of the present invention to provide a heater core of a vehicle.
In addition, an object of the present invention is to provide a heater core of a vehicle capable of shortening the preheating time of the engine by heating the cooling water simultaneously with air heating by integrally configuring the cooling water circulation path in the heater core.

상기와 같이 구성된 본 발명의 실시예를 설명하면 다음과 같다.Referring to the embodiment of the present invention configured as described above are as follows.

차량 엔진을 냉각시키는 냉각수는 엔진을 냉각하여 온도가 상승되어 있고 이때 히터 코어(1)의 냉각수 유입구(2)을 통해 유입된 후 외부의 공기와의 열교환이 되며 온도가 하강하여 냉각수 유출구(3)를 통해 외부로 배출된다. The coolant that cools the vehicle engine is cooled to cool the engine and the temperature is increased. At this time, the coolant flows in through the coolant inlet 2 of the heater core 1 and then heat exchanges with the outside air. Is discharged to the outside through.

엔진 동작 초기에는 냉각수의 온도가 낮기 때문에 공기와의 열교환에 의해 공기의 온도 상승 효과가 매우 적다. Since the temperature of the coolant is low at the beginning of engine operation, the effect of temperature increase of the air due to heat exchange with air is very small.

이때 공기의 온도를 적정 수준으로 상승시키기 위해 본 발명을 사용하도록 한다. At this time, to use the present invention to raise the temperature of the air to an appropriate level.

운전자에 의해 차량의 엔진이 시동되었을 때 냉각수의 온도가 낮은 시기 즉, 엔진 동작 초기 또는 아이들(idle) 상태 지속 시기에만 본 발명을 사용하는 것이 바람직하다. It is preferable to use the invention only at a time when the temperature of the coolant is low when the engine of the vehicle is started by the driver, that is, at the initial stage of engine operation or in an idle state.

엔진 냉각수의 수온을 측정하는 수온 센서(35)는 냉각수의 온도를 측정하고 이에 해당하는 신호를 출력하여 제어부(30)로 입력되도록 한다. 제어부(30)는 냉각수의 온도가 기준값 이하인 것으로 판단되면 제어 신호를 출력하여 릴레이(RY)가 ON 동작하도록 한다. The water temperature sensor 35 measuring the water temperature of the engine coolant measures the temperature of the coolant and outputs a signal corresponding thereto to be input to the controller 30. If it is determined that the temperature of the cooling water is equal to or lower than the reference value, the controller 30 outputs a control signal to allow the relay RY to be turned on.

릴레이(RY)의 ON 동작에 의해 차량의 발전기 또는 차량의 배터리에서 공급되는 전원이 히터 코어(1)의 전기발열소자(PTC)(20)로 인가된다. The power supplied from the generator of the vehicle or the battery of the vehicle is applied to the electric heating element (PTC) 20 of the heater core 1 by the ON operation of the relay RY.

전원선의 + 선과 - 선은 전기발열소자(PTC)(20)의 상부면과 하부면에 각각 밀착되어 있는 전극판(40)으로 연결되어 있어, 차량의 발전기 또는 차량의 배터리에서 공급되는 전원이 공급되도록 하고, 공급된 전원은 전극판(40)을 통하여 전기발열소자(PTC)(20)에 입력되어 전기발열소자(PTC)(20)에서 발열이 이루어지도록 한다. The + and-lines of the power line are connected to the electrode plate 40 which is in close contact with the upper and lower surfaces of the electric heating element (PTC) 20, so that power supplied from the vehicle's generator or the battery of the vehicle is supplied. The supplied power is input to the electric heat generating element (PTC) 20 through the electrode plate 40 to generate heat in the electric heat generating element (PTC) 20.

이때 전원이 연결되어 있는 전극판(40)과 하우징(10)이 접촉되어 히터 코어(1) 본체에 전기가 통전되는 것을 방지하기 위하여 하우징(10)과 전극판(40)의 사이에는 절연 필름(60)을 위치시켜 외부에서 공급되는 전원이 하우징(10)을 통해 외부로 누설되는 것을 방지하도록 한다. At this time, in order to prevent the electrode plate 40, which is connected to the power supply, and the housing 10 from being in contact with each other, electricity is supplied to the body of the heater core 1, an insulating film (between the housing 10 and the electrode plate 40). Position 60 to prevent the power supplied from the outside to leak through the housing 10 to the outside.

전기발열소자(PTC)(20)에서 발열된 열은 하우징(10)을 통해 외부로 전달되며, 하우징(10)의 표면에 접합되어 있는 방열핀(5)으로 인가된다. Heat generated in the electric heat generating element (PTC) 20 is transferred to the outside through the housing 10, and is applied to the heat dissipation fins 5 bonded to the surface of the housing 10.

방열핀(5)의 주위로는 공기가 통과되므로, 방열핀(5) 주위를 공기가 통과하면서 전기발열소자(PTC)(20)에서 발열된 열에 의해 공기의 온도가 증가하게 된다. Since air passes around the heat dissipation fins 5, the air temperature is increased by heat generated by the electric heat generating element (PTC) 20 while air passes through the heat dissipation fins 5.

히터 코어(1)를 통과하는 공기의 온도가 증가되므로 차량의 엔진 동작 초기에도 적절한 난방 효과를 얻을 수 있게 된다.
또한, 방열핀(5)을 통해 전기발열소자(PTC)(20)에서 발생된 열이 히터 코어(1) 상에 형성된 복수의 냉각수 순환로(4)로 전달되어 냉각수를 함께 가열한다.
공기의 가열과 동시에 냉각수의 가열이 이루어지므로, 엔진의 예열 시간을 단축시켜 엔진의 성능 향상을 가져올 수 있다.Since the temperature of the air passing through the heater core 1 is increased, it is possible to obtain a proper heating effect even in the initial engine operation of the vehicle.
In addition, heat generated from the electric heat generating element (PTC) 20 is transferred to the plurality of cooling water circulation paths 4 formed on the heater core 1 through the heat dissipation fins 5 to heat the cooling water together.
Since the cooling water is heated at the same time as the heating of the air, the preheating time of the engine can be shortened and the performance of the engine can be improved.

상기와 같이 동작이 이루어지는 동안 수온 센서(35)는 계속적으로 냉각수의 온도를 측정하여 해당하는 신호를 출력한다, 수온 센서(35)에서 출력되는 신호를 입력받은 제어부(30)는 냉각수의 온도가 일정 수준이상으로 상승된 것으로 판단되었을 때 제어 신호를 출력하여 릴레이(RY)가 오프되도록 한다. While the operation is performed as described above, the water temperature sensor 35 continuously measures the temperature of the cooling water and outputs a corresponding signal. The controller 30 which receives the signal output from the water temperature sensor 35 has a constant temperature of the cooling water. When it is determined that the controller is raised above the level, the control signal is output so that the relay RY is turned off.

릴레이(RY)의 오프(OFF) 동작에 의해 전기발열소자(PTC)(20) 주위의 전극판(40)으로 더 이상의 전원이 공급되지 않게 된다. The OFF operation of the relay RY no longer supplies power to the electrode plate 40 around the electric heating element (PTC) 20.

즉, 전기발열소자(PTC)(20)에서 발열되는 열이 없어도 충분한 난방 효과를 얻을 수 있으므로, 과도한 전원 소비를 방지하기 위함이다. That is, even if there is no heat generated in the heat generating element (PTC) 20 can be obtained a sufficient heating effect, to prevent excessive power consumption.
