본 발명은 난방성능 향상구조에 관한 것으로, 더욱 상세하게는 히터 코어에 발열소자를 형성하고, 이 히티 코어의 내부를 순환하는 냉각수의 온도를 단시간에 상승시킬 수 있게 제어부를 구비하며, 상기 히터 코어와 열교환된 공기가 통과하도록 보조히터를 형성하여 겨울철 초기 운전 시, 단시간에 엔진 최적의 온도에 도달 할 수 있고, 냉각수의 온도를 상승시킬 수 있으며, 히터 코어의 온도를 상승시켜 실내로 토출되는 공기와 열교환이 이루어짐으로 난방효율을 향상시킬 수 있음은 물론, 상기 히터 코어의 발열소자와 보조히터에 의해 더욱 온도를 상승시킬 수 있음으로 최단시간에 난방효율을 향상시킬 수 있는 자동차 난방성능 향상구조에 관한 것이다.The present invention relates to a heating performance improving structure, and more particularly, a heating element is formed in the heater core, and the control unit is provided to raise the temperature of the cooling water circulating in the heater core in a short time. By forming an auxiliary heater to allow the heat exchanged with the air to pass through, it is possible to reach the optimum temperature of the engine in a short time during the initial operation in winter, to increase the temperature of the coolant, and to increase the temperature of the heater core to discharge the air into the room. Heating efficiency can be improved by heat exchange with the car heating performance improvement structure that can improve the heating efficiency in the shortest time by increasing the temperature by the heating element and the auxiliary heater of the heater core. It is about.

일반적으로, 자동차의 내부에는 난방을 목적으로 하는 난방장치가 구비되어 겨울철 자동차 실내의 난방을 담당하게 된다.In general, the inside of the car is provided with a heating device for heating purposes to be responsible for heating the car interior in winter.

상기 난방장치는 엔진의 열에 의해 온도가 상승된 냉각수가 히터 코어를 순환하면서 공기와 열교환이 이루어지며, 온도가 상승된 공기가 자동차 실내로 송풍되어 실내 난방이 이루어진다.The heating device heat exchanges with the air while the coolant whose temperature is increased by the heat of the engine circulates through the heater core, and the heated air is blown into the vehicle interior to perform indoor heating.

도 1은 종래 블로워 및 에어밴트를 도시한 도면이다.1 is a view showing a conventional blower and air vent.

도면에서 도시한 바와 같이, 공기가 블로워(10)의 송풍팬(20)에 의해 에어밴트(30)로 이동되는 과정에 히터 코어(40)를 거치며 열교환이 이루어지고, 이 열교환되어 온도가 상승된 공기가 자동차 실내로 송풍된다.As shown in the figure, heat is exchanged through the heater core 40 in the process of moving the air to the air vent 30 by the blower fan 20 of the blower 10, the heat exchange is increased Air is blown into the car interior.

이때, 상기 히터 코어(40)는 엔진(50)과 열교환되어 온도가 상승된 냉각수가 통과하게 되어 온도가 상승되는 것이고, 온도가 상승된 히터 코어(40)는 상기 송풍팬(20)에 의해 송풍된 공기와 열교환이 이루어져 난방이 이루어진다.In this case, the heater core 40 is heat-exchanged with the engine 50 so that the cooling water having a temperature rises to pass therethrough, and thus the temperature is increased, and the heater core 40 having a temperature rise is blown by the blower fan 20. Heat is exchanged with the supplied air for heating.

그러나, 상기 히터 코어(40)의 온도를 상승시키는 냉각수는 엔진(50)의 열에 의해 그 온도가 상승됨으로 상기 엔진의 온도가 상승되지 않으면 난방효율도 저하되는 문제점이 있었다.However, the cooling water for raising the temperature of the heater core 40 has a problem that the heating efficiency is also lowered if the temperature of the engine does not increase because the temperature is increased by the heat of the engine 50.

특히, 겨울철 초기 운전 시, 상기 엔진은 차가운 외기에 의해 온도 상승시간이 지체되어 난방의 효율이 저하되는 문제점이 있었다.In particular, during the initial winter operation, the engine has a problem that the temperature rise time is delayed due to cold outside air, thereby lowering the heating efficiency.

이에 본 발명은 상기와 같은 문제점들을 해소하기 위해 안출된 것으로써, 히터 코어에 발열소자를 형성하고, 이 히티 코어의 내부를 순환하는 냉각수의 온도를 단시간에 상승시킬 수 있게 제어부를 구비하며, 상기 히터 코어와 열교환된 공기가 통과하도록 보조히터를 형성하여 겨울철 초기 운전 시, 단시간에 엔진 최적의 온도에 도달할 수 있고, 냉각수의 온도를 상승시킬 수 있으며, 히터 코어의 온도를 상승시켜 실내로 토출되는 공기와 열교환이 이루어짐으로 난방효율을 향상시킬 수 있음은 물론, 상기 히터 코어의 발열소자와 보조히터에 의해 더욱 온도를 상승시킬 수 있음으로 최단시간에 난방효율을 향상시킬 수 있는 자동차 난방성능 향상구조를 제공하는 것이 목적이다.
In order to solve the above problems, the present invention provides a control unit to form a heating element in the heater core and to raise the temperature of the cooling water circulating in the heater core in a short time. By forming an auxiliary heater to allow the heat exchanged with the heater core to pass through, it is possible to reach the optimum temperature of the engine in a short time during the initial operation in winter, to increase the temperature of the coolant, and to increase the temperature of the heater core and discharge it into the room. The heating efficiency can be improved by heat exchange with the air, and the temperature can be further increased by the heating element and the auxiliary heater of the heater core, thereby improving the heating performance of the car, which can improve the heating efficiency in the shortest time. The purpose is to provide a structure.

상기 목적을 이루기 위한 본 발명은, 다수개의 히터 튜브로 이루어지는 히터 코어와; 상기 히터 코어에 구비되어 열을 발생시키는 발열소자와; 상기 히터 코어의 히터 튜브 사이를 통과한 공기의 온도를 더욱 상승시킬 수 있도록 구비된 보조 히터와; 냉각수가 엔진과 상기 히터 코어 및 라디에이터를 거친 후 다시 엔진으로 순환되도록 형성된 냉각수관과; 상기 냉각수관의 구간 중 엔진과 히터 코어 사 이에 구비되어 냉각수의 유량을 조절하는 유량제어부를 포함하여 이루어진다.The present invention for achieving the above object is a heater core consisting of a plurality of heater tubes; A heating element provided in the heater core to generate heat; An auxiliary heater provided to further increase the temperature of the air passing between the heater tubes of the heater core; A coolant pipe configured to circulate the coolant back to the engine after passing through the engine, the heater core and the radiator; It is provided between the engine and the heater core of the section of the coolant pipe comprises a flow control unit for adjusting the flow rate of the coolant.

바람직하게, 상기 발열소자는 PTC로 이루어져 상기 히터 튜브에 지그재그로 형성되고, 자동차 속도와 엔진 온도 및 냉각수 온도에 의해 자동으로 작동되도록 소자제어부가 형성된다.Preferably, the heating element is made of PTC is formed in a zigzag on the heater tube, the element control unit is formed to be automatically operated by the vehicle speed, the engine temperature and the coolant temperature.

그리고, 상기 유량제어부는 냉각수의 온도 및 엔진의 rpm에 따라 유량을 조절하도록 형성된다.The flow rate controller is configured to adjust the flow rate according to the temperature of the cooling water and the rpm of the engine.

상기와 같은 구성에 의하면, 겨울철 초기 운전 시, 냉각수가 냉각수관을 순환하는 것을 일정시간 차단하여 단시간에 엔진의 성능을 발휘할 수 있는 온도에 도달할 수 있고, 이 엔진과 열교환된 냉각수의 온도를 상승시킬 수 있으며, 이 온도가 상승된 냉각수가 히터 코어를 이동하면서 실내로 토출되는 공기와 열교환이 이루어져 난방효율을 향상시킬 수 있음은 물론, 상기 히터 코어에 발열소자를 구비하여 히터 코어의 온도를 더욱 상승시킬 수 있고, 이 히터 코어를 거친 공기가 보조히터를 거치며 더욱 온도를 상승시킬 수 있음으로 최단시간에 난방효율을 향상시킬 수 있다.According to the configuration as described above, during the initial winter operation, the cooling water can be circulated through the cooling water pipe for a certain time to reach a temperature at which the engine performance can be exhibited in a short time, and the temperature of the cooling water heat exchanged with the engine is raised. It is possible to improve the heating efficiency by the heat exchanged with the air discharged into the room while the coolant with the elevated temperature is moved to the heater core, as well as to improve the heating efficiency of the heater core by further providing a temperature of the heater core The heating efficiency can be increased, and the air passing through the heater core can further increase the temperature through the auxiliary heater, thereby improving heating efficiency in the shortest time.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

또한, 본 실시예는 본 발명의 권리범위를 한정하는 것은 아니고 단지 예시로 제시된 것이며, 그 기술적 요지를 이탈하지 않는 범위내에서 다양한 변경이 가능하다.In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only, and various modifications may be made without departing from the technical gist of the present invention.

도 2는 본 발명에 따른 자동차 난방성능 향상구조를 도시한 도면이다.2 is a view showing a vehicle heating performance improvement structure according to the present invention.

도면에서 도시한 바와 같이, 공기조화장치에서 열교환된 공기를 자동차 실내 로 송풍하도록 블로워(10)가 형성되고, 이 블로워(10)의 일 측에는 에어덕트(40)가 형성되어 열교환된 공기를 자동차 실내로 안내하게 된다.As shown in the figure, a blower 10 is formed to blow the heat exchanged air in the air conditioner into the vehicle interior, and an air duct 40 is formed at one side of the blower 10 to exchange the heat exchanged air in the vehicle interior. You will be directed to.

상기 블로워(10) 내부에는 송풍팬(20)이 형성되고, 이 송풍팬(20)을 구동시키는 송풍모터(22)가 구비된다.A blower fan 20 is formed inside the blower 10, and a blower motor 22 for driving the blower fan 20 is provided.

그리고, 상기 에어덕트(30)에는 증발기(42)와 히터 코어(40)가 형성되고, 이 히터 코어(40)를 거친 공기가 통과하도록 보조히터(110)가 구비되며, 상기 히터 코어(40)와 보조히터(110)의 공기 통과량을 조절하는 에어 믹스 도어가 형성되며, 공기가 토출되는 각 토출구와 이 토출구를 개폐하는 댐퍼가 각각 형성된다.In addition, an evaporator 42 and a heater core 40 are formed in the air duct 30, and an auxiliary heater 110 is provided to allow air that passes through the heater core 40 to pass through the heater core 40. And an air mix door for adjusting the air passage amount of the auxiliary heater 110, and each discharge port through which air is discharged and a damper for opening and closing the discharge port are respectively formed.

이때, 상기 히터 코어(40)는 다수개의 히터 튜브로 구성되고, 이 히터 튜브에는 발열소자(100)가 구비되어 자체 열을 발산하는데, 이 발열소자(100)는 PTC로 이루어짐으로 자체 발열이 가능하며, 상기 히터 코어(40)의 온도를 상승시키주는 역할을 하게 된다.At this time, the heater core 40 is composed of a plurality of heater tubes, the heater tube is provided with a heat generating element 100 to emit its own heat, the heat generating element 100 is made of PTC can be self-heating And, it serves to increase the temperature of the heater core 40.

상기 PTC 발열소자(100)는 히터 튜브에 지그재그로 형성되고, 자동차 속도와 엔진 온도 및 냉각수 온도에 의해 자동으로 작동되도록 소자제어부가 형성되어 자동으로 제어됨이 바람직하다.The PTC heating element 100 is zigzag formed in the heater tube, it is preferable that the element control unit is formed and automatically controlled to operate automatically by the vehicle speed, the engine temperature and the coolant temperature.

그리고, 상기 히터 코어(40)의 온도는 그 내부를 순화하는 냉각수에 의해 정해지는데, 이 냉각수는 엔진(50)을 순환하며 열교환이 이루짐으로 온도가 상승되고, 이 온도가 상승된 냉각수가 상기 히터 코어(40)를 거치며 공기와 열교환이 이루어짐으로 냉각수의 온도는 저하되고, 공기의 온도는 상승된다.In addition, the temperature of the heater core 40 is determined by the cooling water for circulating the inside thereof, and the cooling water circulates through the engine 50 and the temperature is increased by heat exchange. As the heat exchange with the air passes through the heater core 40, the temperature of the cooling water is lowered and the temperature of the air is increased.

이때, 상기 냉각수가 엔진(50)을 거쳐 히터 코어(40)로 이동되는 냉각수관(60)에 유량제어부(120)가 형성되어 그 유량을 조절하는 것으로 상기 엔진(50)에 유입된 냉각수를 단속하여 단 시간에 온도를 상승시키고, 이 온도가 상승된 냉각수를 히터 코어(40)로 이동시킴으로 공기와 열교환되어 공기의 온도를 상승시킬 수 있다.At this time, the flow rate control unit 120 is formed in the coolant pipe 60 through which the coolant moves to the heater core 40 through the engine 50 to regulate the flow rate to interrupt the coolant introduced into the engine 50. In this case, the temperature is increased in a short time, and the coolant having the elevated temperature is moved to the heater core 40 to exchange heat with the air, thereby increasing the temperature of the air.

상기 유량제어부(120)는 냉각수의 온도 및 엔진의 rpm에 따라 유량을 자동 조절하도록 구비하여 엔진(50)의 과열을 방지함이 바람직하다.The flow control unit 120 is preferably provided to automatically adjust the flow rate according to the temperature of the cooling water and the rpm of the engine to prevent overheating of the engine 50.

특히, 상기 히터 코어(40)에는 PTC로 이루어진 발열소자(100)에 의해 그 온도는 더욱 상승되며, 더욱 온도가 상승된 히터 코어(40)와 열교환되는 공기는 보조히터(110)를 거치며 다시 한번 온도가 상승된다.In particular, the temperature of the heater core 40 is further increased by the heating element 100 made of PTC, and the air that is heat-exchanged with the heater core 40 whose temperature is further increased is passed through the auxiliary heater 110 once again. The temperature rises.

이와 같이, 냉각수를 단속하여 단시간에 냉각수의 온도를 상승시키고, 이 냉각수의 열에 의해 히터 코어(40)의 온도를 상승시키는 동시에 PTC 발열소자(100)를 이용하여 히터 코어(40)의 온도를 더욱 상승시켜 송풍되는 공기와 열교환되어 공기의 온도가 상승되고, 이 온도가 상승된 공기는 다시 보조히터(110)를 통과하며 다시 한번 열교환이 이루어진 다음, 자동차 실내로 송풍되어 난방이 이루어진다.In this way, the cooling water is interrupted to raise the temperature of the cooling water in a short time, and the temperature of the heater core 40 is increased by the heat of the cooling water, and the temperature of the heater core 40 is further increased by using the PTC heating element 100. The heat is raised and heat-exchanged with the blown air to increase the temperature of the air. The air whose temperature is raised passes again through the auxiliary heater 110 and heat exchanges once again, and is then blown into the vehicle interior to perform heating.
