Description

차량용 피티씨 히터Car PTC heater
본 발명은 차량용 피티씨 히터에 관한 것으로써, 더욱 상세하게는 하나의 피티씨 히터에 복수개 코어(제1코어,제2코어)를 독립 구성함과 아울러 상기 각 코어를 공조케이스의 제1통로와 제2통로에 배치하여 독립 제어하도록 한 차량용 피티씨 히터에 관한 것이다.The present invention relates to a vehicle PTC heater, and more particularly, a plurality of cores (first core, second core) independently configured in one PTC heater and each of the cores and the first passage of the air conditioning case. A vehicle PTC heater is disposed in a second passage so as to be independently controlled.
일반적으로 차량용 공조장치는 차량 외부의 공기를 차량 실내로 도입하거나, 차량 실내의 공기를 순환시키는 과정에서 가열 또는 냉각시킴으로써 차량 실내를 냉방 또는 난방하기 위한 장치로써, 공조케이스의 내부에는 냉각작용을 위한 증발기와, 가열작용을 위한 히터코어 및 상기 증발기나 히터코어에 의해 냉각 또는 가열된 공기를 송풍모드 전환용 도어를 사용하여 차량 실내의 각 부분으로 선택적으로 송풍하도록 이루어져 있다.In general, a vehicle air conditioner is a device for cooling or heating an interior of a vehicle by introducing air outside the vehicle into a vehicle interior or by heating or cooling the air in a vehicle circulating the vehicle. The evaporator, the heater core for the heating action, and the air cooled or heated by the evaporator or the heater core are selectively blown to each part of the vehicle interior by using a blowing mode switching door.
상기 차량용 공조장치의 일예로 도 1에 도시된 바와 같이, 입구측에 공기유입구(11)가 형성되고 출구측에는 복수의 공기토출구(12)가 형성된 공조케이스(10)와, 상기 공조케이스(10)의 내부에 설치되는 증발기(1) 및 히터코어(2)와, 상기 증발기(1)와 히터코어(2)의 사이에 설치되어 온도를 조절하는 템프도어(20)와, 상기 공기토출구(12)에 설치되어 공조모드에 따라 공기토출구(12)의 개도를 조절하는 모드도어(30)를 포함하여 이루어진다.As an example of the vehicle air conditioner, as shown in FIG. 1, an air inlet 11 is formed at an inlet side and a plurality of air outlets 12 are formed at an outlet side, and the air conditioning case 10. An evaporator 1 and a heater core 2 installed in the interior thereof, a temporal door 20 installed between the evaporator 1 and the heater core 2 to control a temperature, and the air outlet 12 Installed in the air conditioning mode comprises a mode door 30 for adjusting the opening degree of the air discharge port (12).
이러한 공조장치는 엔진에 의해 가열된 냉각수가 상기 히터코어(2)를 순환하게 하여 난방을 실시하게 된다. 그러나, 시동 초기에는 냉각수의 온도가 낮기 때문에 냉각수를 이용한 난방을 할 수가 없다. 이에 따라 시동 초기의 난방을 위한 보조 난방장치로 배터리의 전기적 에너지를 이용하여 난방을 할 수 있도록 하는 피티씨 히터(5)가 사용되고 있다.Such an air conditioner causes the cooling water heated by the engine to circulate the heater core 2 to perform heating. However, since the temperature of the cooling water is low at the beginning of the startup, heating using the cooling water cannot be performed. Accordingly, the PTC heater 5 is used as an auxiliary heating device for heating at the start-up to enable heating by using electric energy of the battery.
아울러, 최근 개발되는 전기자동차용 공조장치에도 피티씨 히터(5)가 설치되고 있는데, 전기자동차용 공조장치에는 엔진의 연소열을 이용하는 히터코어(2)는 설치할 수 없기 때문에, 상기 피티씨 히터(5)가 메인 난방장치 역할을 하게 된다.In addition, the PTC heater 5 is also installed in an air vehicle air conditioner that is recently developed. Since the heater core 2 using the combustion heat of the engine cannot be installed in the air vehicle air conditioner, the PTC heater 5 ) Will serve as the main heating system.
도 2는 피티씨 히터를 나타낸 도면으로서, 상기 피티씨 히터(5)는, PTC소자 및 +터미널이 내장된 히팅로드(6)와, PTC소자 및 -터미널이 내장된 히팅로드(6)를 상호 일정간격 이격하여 복수개 배치하고, 상기 각 히팅로드(6)의 사이에는 방열핀(7)을 개재하여 구성된다.FIG. 2 is a diagram showing a PTC heater, wherein the PTC heater 5 includes a heating rod 6 incorporating a PTC element and a + terminal, and a heating rod 6 incorporating a PTC element and a-terminal. It is arranged a plurality of spaced apart at regular intervals, it is configured via the heat dissipation fin (7) between the heating rods (6).
상기 피티씨 히터(5)의 일측에는 상기 각 히팅로드(6)의 +터미널 및 -터미널에 공급되는 전압을 제어하는 전압제어소자(미도시)가 구비된 제어부(8)가 설치되어 있다.One side of the PTC heater 5 is provided with a controller 8 having a voltage control element (not shown) for controlling the voltage supplied to the + terminal and the-terminal of each heating rod 6.
따라서, 차실내 설정온도에 대응하는 PWM(Pulse Width Modulation) 신호의 듀티비(duty ratio) 제어를 통해 피티씨 히터(5)에 공급되는 전압을 가변 제어하게 된다.Therefore, the voltage supplied to the PTC heater 5 is variably controlled by controlling a duty ratio of a pulse width modulation (PWM) signal corresponding to an indoor setting temperature.
즉, PWM신호의 듀티비에 의해 상기 피티씨 히터(5) 제어부(8)의 전압제어소자는 각 히팅로드(6)의 터미널로 공급되는 전압을 가변하게 되고, 이때 터미널에 부착된 PTC소자의 출력온도(발열량)가 가변하게 되면서 상기 방열핀(7)을 통과하는 공기를 가열하게 된다.That is, the voltage control element of the PTC heater 5 control unit 8 varies the voltage supplied to the terminals of the heating rods 6 by the duty ratio of the PWM signal. As the output temperature (heating amount) is variable, the air passing through the heat radiation fins 7 is heated.
그리고, 일반적인 공조장치의 공조케이스(10)에는 도 2와 같이 하나의 피티씨 히터(5)가 설치되지만, 좌,우(운전석,조수석) 독립제어가 가능한 공조장치와 같이 공조케이스(10)의 내부가 세퍼레이터(13)에 의해 좌측통로(10a)와 우측통로(10b)로 구획된 경우에는 도 3과 같이 두개의 피티씨 히터(5)를 설치하게 되며, 이렇게 상기 공조케이스(10)내의 좌측통로(10a)와 우측통로(10b)에 각각 피티씨 히터(5)를 하나씩 장착해야 완벽한 좌,우 독립제어가 가능하다.The air conditioner case 10 of the general air conditioner is provided with one PTC heater 5 as shown in FIG. 2, but the air conditioner case 10 is the same as the air conditioner capable of independent control of left and right (driver's seat and front passenger's seat). When the interior is partitioned into the left passage 10a and the right passage 10b by the separator 13, two PTC heaters 5 are installed as shown in FIG. 3, and thus the left side of the air conditioning case 10 is installed. Only one PTC heater 5 is mounted in each of the passage 10a and the right passage 10b to allow perfect left and right independent control.
그러나, 상기 공조케이스(10)에 두개의 피티씨 히터(5)를 장착하게 되면, 제조비용과 무게가 증가하는 문제가 있고, 이로인해 차량 연비 및 생산성도 저하되는 문제가 있다.However, when the two PTC heaters 5 are mounted on the air conditioning case 10, there is a problem in that manufacturing cost and weight are increased, thereby deteriorating vehicle fuel economy and productivity.
상기한 문제점을 해결하기 위한 본 발명의 목적은 하나의 피티씨 히터에 복수개 코어(제1코어,제2코어)를 독립 구성함과 아울러 상기 각 코어를 공조케이스의 제1통로와 제2통로에 배치하여 독립 제어함으로써, 좌,우 독립제어를 위해 하나의 피티씨 히터를 사용하므로 제조비용과 무게를 감소함은 물론 차량 연비 및 생산성을 향상하고, 피티씨 히터를 사용하는 다른 차량에도 쉽게 적용할 수 있는 차량용 피티씨 히터를 제공하는데 있다.An object of the present invention for solving the above problems is to independently configure a plurality of cores (first core, second core) in one PTC heater, and each of the cores in the first passage and the second passage of the air conditioning case Independent control by arranging, using one PTC heater for independent control of left and right, reduces manufacturing cost and weight, improves vehicle fuel economy and productivity, and can be easily applied to other vehicles using PTC heater.

또한, 상기 세퍼레이터(120)는 상기 증발기(101)의 하류측에서부터 상기 공기토출구까지 공조케이스(110)의 내부를 제1통로(110a)와 제2통로(110b)로 분할하게 된다.In addition, the separator 120 divides the interior of the air conditioning case 110 into a first passage 110a and a second passage 110b from the downstream side of the evaporator 101 to the air discharge port.
한편, 도면에서는, 상기 증발기(101)와 피티씨 히터(130)의 사이에 온도조절도어가 없는 구조를 일예로 도시하였지만, 목적에 따라서 온도조절도어를 설치할 수도 있다.On the other hand, in the figure, although the structure without the temperature control door between the evaporator 101 and the PTC heater 130 is shown as an example, a temperature control door may be provided according to the purpose.
그리고, 상기 피티씨 히터(130)는 단일 피티씨 히터(130)로서, 상기 공조케이스(110)의 복수개 통로 즉, 제1통로(110a)와 제2통로(110b)에 걸쳐지게 삽입 설치되는 하우징(131)과, 상기 하우징(131)의 내측에서 상기 복수개 통로상에 각각 코어를 배치하여 구성된 코어부(132)를 포함하여 구성된다.In addition, the PTC heater 130 is a single PTC heater 130, the housing which is inserted to be installed across the plurality of passages, that is, the first passage (110a) and the second passage (110b) of the air conditioning case 110. 131 and a core portion 132 formed by arranging cores on the plurality of passages inside the housing 131.

따라서, 상기 피티씨 히터(130)의 제1코어(133)와 제2코어(134)를 독립 제어하게 되면, 상기 공조케이스(110)의 제1통로(110a)와 제2통로(110b)를 유동하는 공기를 독립적으로 가열할 수 있다.Accordingly, when the first core 133 and the second core 134 of the PTC heater 130 are independently controlled, the first passage 110a and the second passage 110b of the air conditioning case 110 are closed. The flowing air can be heated independently.
즉, 상기 제1코어(133)와 제2코어(134)의 발열량을 다르게 제어하면, 상기 제1통로(110a)와 제2통로(110b)를 유동하는 공기의 온도를 다르게 조절할 수 있어, 차실내의 운전석과 조수석으로 토출되는 공기 온도를 다르게 할 수 있는 것이다.In other words, if the calorific values of the first core 133 and the second core 134 are controlled differently, the temperature of the air flowing through the first passage 110a and the second passage 110b may be adjusted differently. It is possible to change the temperature of the air discharged to the driver's seat and passenger seat in the room.
상기 하우징(131)은, 제1,2케이스(131a,131b)가 서로 조립되어 상기 코어부(132)의 가장자리를 고정하게 되고, 상기 하우징(131)의 일측에는 상기 제1코어(133)와 제2코어(134)로 공급되는 전압을 제어하는 제어부(136)가 구비된다.In the housing 131, first and second cases 131a and 131b are assembled with each other to fix an edge of the core part 132, and the first core 133 and the first core 133 are fixed to one side of the housing 131.

상기 제어부(136)에는, PCB기판(미도시)과, 후술하는 히팅로드(132a)의 +터미널 및 -터미널에 공급되는 전압을 제어하는 전압제어소자(미도시)를 포함하여 구성된다.The control unit 136 includes a PCB substrate (not shown) and a voltage control element (not shown) for controlling the voltage supplied to the + terminal and the-terminal of the heating rod 132a to be described later.
또한, 상기 제어부(136)는, 상기 제1코어(133)와 제2코어(134)의 히팅로드(132a)와 평행한 상기 하우징(131)의 일측에 구비된다.In addition, the control unit 136 is provided on one side of the housing 131 parallel to the heating rod 132a of the first core 133 and the second core 134.
즉, 종래에서는 상기 코어부의 히팅로드가 상기 제어부를 향해 배치된 반면, 본발명에서는 상기 코어부(132)의 히팅로드(132a)가 제어부(136)와 평행하게 배치되는 구조이기 때문에 상기 하우징(131)의 가장자리 내부를 통해 상기 제어부(136)의 PCB기판과 상기 히팅로드(132a)의 +터미널 및 -터미널을 연결하게 된다.That is, in the related art, the heating rod of the core part is disposed toward the controller, whereas in the present invention, the heating rod 132a of the core part 132 is disposed in parallel with the control part 136. The + terminal and-terminal of the PCB and the heating rod 132a of the control unit 136 are connected through the inside of the edge.
한편, 상기 피티씨 히터(130)는, 상기 코어부(132)만 공조케이스(110)의 내부로 삽입되고, 상기 제어부(136)는 상기 공조케이스(110)의 외측면측에 위치하도록 설치된다.On the other hand, the PTC heater 130, only the core portion 132 is inserted into the air conditioning case 110, the control unit 136 is installed so as to be located on the outer surface side of the air conditioning case 110. .
그리고, 상기 제1코어(133)와 제2코어(134)는, 각각 복수개의 히팅로드(132a)와, 상기 복수개의 히팅로드(132a) 사이에 설치되는 방열핀(132b)으로 구성된다.The first core 133 and the second core 134 each include a plurality of heating rods 132a and heat dissipation fins 132b provided between the plurality of heating rods 132a.
이때, 상기 제1코어(133)의 히팅로드(132a)와 상기 제2코어(134)의 히팅로드(132a)는 서로 평행하게 설치된다.At this time, the heating rod 132a of the first core 133 and the heating rod 132a of the second core 134 are installed in parallel with each other.
그리고, 상기 제1코어(133)의 히팅로드(132a)와 상기 제2코어(134)의 히팅로드(132a)는, 상기 공조케이스(110)내 좌,우방향에 대해 수직으로 설치된다.The heating rod 132a of the first core 133 and the heating rod 132a of the second core 134 are installed perpendicularly to the left and right directions in the air conditioning case 110.
즉, 종래에는 상기 피티씨 히터의 히팅로드가 공조케이스의 내부를 가로질러 좌,우방향으로(수평으로) 설치되었지만, 본발명에서는 상기 피티씨 히터(130)의 히팅로드(132a)가 공조케이스(110)의 내부에 수직방향으로 설치된 것이다.That is, in the related art, the heating rod of the PTC heater is installed in the left and right directions (horizontally) across the inside of the air conditioning case, but in the present invention, the heating rod 132a of the PTC heater 130 is an air conditioning case. It is installed in the vertical direction inside the (110).
다시말해, 상기 공조케이스(110)의 좌측면 또는 우측면을 통해 상기 피티씨 히터(130)를 공조케이스(110)의 내부로 삽입하여 장착하게 되는데, 이때 상기 피티씨 히터(130)를 공조케이스(110)에 삽입하는 방향에 대해 직각방향으로 상기 히팅로드(132a)가 설치되는 것이다.In other words, the PTC heater 130 is inserted into the air conditioning case 110 through the left side or the right side of the air conditioning case 110. In this case, the PTC heater 130 is installed in the air conditioning case ( The heating rod 132a is installed in a direction perpendicular to the direction of insertion into the 110.
상기와 같은 히팅로드(132a)의 설치구조로 인해, 단일 피티씨 히터(130)에서 상기 제1코어(133)와 제2코어(134)를 독립 제어할 수 있는 것이다.Due to the installation structure of the heating rod 132a as described above, the first core 133 and the second core 134 can be independently controlled by the single PTC heater 130.
한편, 상기 히팅로드(132a)는, +터미널(미도시) 및 PTC소자(미도시)가 내장된 히팅로드(132a)와, -터미널(미도시) 및 PTC소자(미도시)가 내장된 히팅로드(132a)가 서로 일정간격 이격되어 교대로 설치된다.Meanwhile, the heating rod 132a may include a heating rod 132a in which a + terminal (not shown) and a PTC element (not shown) are embedded, and a heating in which a terminal (not shown) and a PTC element (not shown) are built in. The rods 132a are alternately installed at regular intervals from each other.
따라서, 상기 제어부(136)를 통해 상기 각 히팅로드(132a)의 +터미널과 -터미널에 전압이 공급되면, PTC소자가 발열하면서 각 히팅로드(132a)가 뜨거워져 방열핀(132b)에 전열되고, 이때 상기 코어부(132)의 각 방열핀(132b)을 통과하는 공기가 가열되게 되는 것이다.Therefore, when the voltage is supplied to the + terminal and the-terminal of each heating rod 132a through the control unit 136, each heating rod 132a is heated while the PTC element is heated, and is heated to the heat radiation fin 132b, At this time, the air passing through each of the heat radiation fins 132b of the core part 132 is heated.
상기 제어부(136)는, 상기 코어부(132)의 제1코어(133)와 제2코어(134)로 공급되는 전압을 가변 제어하여 제1코어(133)와 제2코어(134)의 발열량을 독립적으로 제어하게 된다.The controller 136 variably controls the voltages supplied to the first core 133 and the second core 134 of the core unit 132 to generate heat of the first core 133 and the second core 134. Will be controlled independently.

The temperatures of 133 and the second core 134 are respectively detected. That is, the first core 133 and the second core 134 are controlled through a temperature sensor installed in the first core 133 and the second core 134.
그리고, 상기 제1코어(133)와 제2코어(134)의 사이에는, 상기 제1코어(133)와 제2코어(134)간에 열전달을 차단하는 열차단부재(135)가 설치된다.And, between the first core 133 and the second core 134, a heat shield member 135 for blocking heat transfer between the first core 133 and the second core 134 is provided.
즉, 상기 제1코어(133)와 제2코어(134)의 발열량을 다르게 제어할 경우, 제1코어(133)와 제2코어(134)간의 불필요한 열전달을 방지하여 성능 저하를 방지하게 된다.That is, when the heat generation amount of the first core 133 and the second core 134 is controlled differently, unnecessary heat transfer between the first core 133 and the second core 134 may be prevented to prevent performance degradation.
상기 열차단부재(135)에는, 피티씨 히터(130)를 통과하는 공기 중 일부가 상기 제1코어(133)와 제2코어(134)를 바이패스하도록 바이패스홀(135a)이 형성되어, 제1코어(133)와 제2코어(134)간의 열전달을 효율적으로 방지하게 된다.In the thermal barrier member 135, a bypass hole 135a is formed such that a part of the air passing through the PTC heater 130 bypasses the first core 133 and the second core 134. The heat transfer between the first core 133 and the second core 134 is effectively prevented.
상기 바이패스홀(135a)를 갖는 열차단부재(135)는, 제1코어(133)와 제2코어(134)간의 불필요한 열전달을 방지하거나 코어부(132)의 온도를 식히게 된다.The heat blocking member 135 having the bypass hole 135a prevents unnecessary heat transfer between the first core 133 and the second core 134 or cools the temperature of the core 132.
한편, 상기 열차단부재(135)는, 격자 형태로 형성되어 상기 바이패스홀(135a)을 격자형태로 형성하게 된다.On the other hand, the thermal barrier member 135 is formed in a lattice form to form the bypass hole 135a in a lattice form.
