Description
본 발명은 에어콘 작동시 에바퍼레이터 코어 아이싱 및 마이그레이션 현상 방지용 더미스터에 관한 것으로 더욱 상세히는, 에어콘의 에바퍼레이터 코어에 장착된 상태에서 온도를 감지하여 에어콘 제어부로 하여금 콤푸레셔의 작동을 온/오프 제어시킬 수 있도록 하는 방식을 통해 코어의 수분이 동결되는 것을 방지하기 위해 사용되는 더미스터의 내부 수밀성을 개선하고 내부로의 수분 침투로 인한 고저항 발생(즉, 마이그레이션(Migration))을 방지할 수 있으며, 또한 칩 납땜시 발생하는 이물질에 의한 저저항 발생을 미연에 방지할 수 있도록 발명한 것이다.The present invention relates to an evacuator core icing and a dummyster for preventing migration phenomena when the air conditioner is operated. More specifically, the air conditioner controls the operation of the compressor on / off by sensing a temperature in a state mounted on the evacuator core of the air conditioner. By controlling it, it is possible to improve the internal watertightness of the dummyster used to prevent the water from freezing in the core and to prevent the occurrence of high resistance (i.e., migration) due to water penetration into the interior. In addition, the invention is invented to prevent the occurrence of low resistance due to foreign substances generated during chip soldering.
일반적으로 더미스터는 에어콘의 에바퍼레이터 코어에 장착된 상태에서 온도를 감지하여 에어콘 제어부로 하여금 콤푸레셔의 작동을 온/오프 제어시킬 수 있도록 하여 코어의 수분이 동결되는 것을 방지하기 위해 사용된다.In general, the dummyster is used to prevent freezing of moisture in the core by sensing the temperature in a state where it is mounted on the evacuator core of the air conditioner so that the air conditioner controller can control the operation of the compressor on / off.
종래의 더미스터는 도 1에 나타낸 바와 같이 더미스터 칩 본체(1)에 두 전선(3)을 납땜 고정시키고, 상기 더미스터 칩 본체(1)와 납땜부 전체 및 전선(3) 일부를 소정 형태를 갖는 케이스(5)에 넣고 그 내부에 칩 코팅제로써 에폭시수지(6)를 충진시켜 고착화시킨 구성으로 되어 있다.In the conventional dummyster, two wires 3 are soldered and fixed to the dummyster chip main body 1, as shown in FIG. 1, and the dummyster chip main body 1, the whole soldering part, and a part of the electric wire 3 are formed in a predetermined form. It was put in the case (5) having the inside and it is made into the structure which filled and fixed the epoxy resin 6 by the chip coating agent inside.
이와같은 구성을 갖는 더미스터를 에어콘의 에바퍼레이터 코어에 장착하고 에어콘을 작동시켰을시 에바퍼레이터 코어를 통과한 차가운 내/외부 공기가 차량 실내로 유입될시 코어 내부의 냉매 온도차에 의해 다량의 수분이 발생하게 되는데, 이 수분이 더미스터 내부로 침투하게 되어 고저항 발생등으로 에어콘 작동 불량으로 이어짐은 물론 에바퍼레이터 코어의 동결로 이어지는 등의 문제점이 있다.When the dummyster having such a configuration is mounted on the evacuator core of the air conditioner and the air conditioner is activated, a large amount of coolant internal / external air passing through the evacuator core flows into the vehicle interior due to the refrigerant temperature difference inside the core. Moisture is generated, this moisture penetrates into the dummy, leading to poor air conditioning operation due to high resistance, etc., as well as lead to freezing of the evaporator core.
즉, 에바퍼리에터 코어 내부의 냉매 온도차에 의해 발생된 다량의 수분이 더미스터 내부로 침투되면 열충격에 의한 칩 크렉이 발생되고, 또 이와 같이 수분 침투시 Ag 이온이 직류전압 인가 상황에서 전압이 낮은 방향으로 이동함으로써 고저항이 발생되어 에어콘이 아예 구동되지 않는 문제점이 있다.In other words, if a large amount of moisture generated by the refrigerant temperature difference inside the evaperator core penetrates into the dummy, a chip crack is generated due to thermal shock. By moving in a low direction, high resistance is generated and there is a problem that the air conditioner is not driven at all.
또한, 더미스터 칩 본체(1)와 전선(3)을 전기적으로 상호 연결시켜 주기 위한 납땜시 납 산화물 등과 같은 이물질이 유입되어 저저항이 발생되는데, 이와 같이 더미스터가 기준 저항 이하로 낮아지면(즉, 저저항) 정확한 온도검출이 이루어지지 않게 되어 에바퍼레이터 자체에서 아이싱(Icing)이 발생되는 문제점도 있다.In addition, when soldering to electrically connect the dummy chip main body 1 and the wire 3 to each other, foreign substances such as lead oxide are introduced to generate low resistance. In other words, low resistance) accurate temperature detection is not made, there is also a problem that the icing (Icing) occurs in the evaporator itself.
본 발명은 이와같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 더미스터 칩 본체의 전극을 금으로 형성하고 칩 코팅제로는 글레스를 사용하되 상기 글레스를 고온에서 소결시키는 방식으로 통해 더미스터의 내부 수밀성을 향상시킬 수 있음은 물론 내부로의 수분 침투로 인한 고저항 발생을 방지할 수 있고, 또 칩 납땜시 발생하는 이물질에 의한 저저항 발생을 미연에 방지하여 더미스터로 인한 에어콘의 작동정지 및 불량을 미연에 방지할 수 있는 어어콘 작동시 에바퍼레이터 코어 아이싱 및 마이그레이션 현상 방지용 더미스터를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, the electrode of the dummy chip chip body is formed of gold and the chip coating agent using a glass, but in the manner of sintering the glass at a high temperature inside the dummyster In addition to improving watertightness, it is possible to prevent the occurrence of high resistance due to moisture penetration into the interior, and also to prevent the occurrence of low resistance due to foreign substances generated during chip soldering. The purpose of the present invention is to provide a dummy core for evacuating the evacuator core icing and migration during an air conditioner that can prevent defects in advance.
상기한 본 발명의 목적은, 전선이 납땜 고정되는 더미스터 칩 본체의 두 전극을 금으로 형성하고, 상기 두 전극을 포함하는 더미스터 칩 본체 전체와 납땜부 및 전선 일부에 입혀지는 코팅제로는 글레스를 사용하여 고온에서 소결시킨 글레스 케이스를 형성시켜 주므로써 달성할 수 있다.The object of the present invention described above is to form two electrodes of the dummyster chip main body in which the electric wires are soldered and fixed with gold, and the coating agent coated on the entire dummyster chip main body including the two electrodes and the soldering part and the electric wire is glass. It can be achieved by forming a glass case sintered at a high temperature using.
따라서, 글레스 케이스로 인해 더미스터의 내부 수밀성을 향상시킬 수 있으므로 그 내부로의 수분 침투를 방지할 수 있어 고저항 발생을 방지할 수 있고, 또전극이 금으로 형성되어 있으므로 칩 납땜시 이물질의 유입을 방지할 수 있어 이물질로 인한 저저항 발생을 미연에 방지할 수 있음에 따라 더미스터로 인한 에어콘의 작동정지 및 불량을 미연에 방지(즉, 더미스터의 신뢰도를 향상)할 수 있는 것이다.Therefore, due to the glass case, the internal watertightness of the dummyster can be improved, thereby preventing the penetration of moisture into the inside of the dummyster, thereby preventing the occurrence of high resistance. Also, since the electrode is made of gold, foreign matters are introduced during chip soldering. It is possible to prevent the occurrence of low resistance due to foreign matters in advance to prevent the operation and failure of the air conditioner due to the dummy in advance (that is, to improve the reliability of the dummy).

따라서, 더미스터의 저항값이 이물질로 인해 기준 저항 이하로 낮아지는 것(즉, 저저항이 되는 것) 자체를 미연에 방지할 수 있어 에어콘의 작동시 더미스터가 정확한 온도값을 검출하여 에어콘 제어부로 입력시켜 주게 되므로 저저항으로 인해발생될 수 있는 에바퍼레이터 자체의 아이싱(Icing)을 미연에 방지할 수 있는 것이다.Therefore, the resistance value of the dummyster is lowered below the reference resistance due to the foreign matter (that is, the low resistance) can be prevented in advance, so that the dummyster detects the correct temperature value when the air conditioner is operated, thereby controlling the air conditioner. As it is inputted as, it is possible to prevent icing of the evaporator itself, which may be caused by low resistance.
또한, 본 발명 장치의 두번째 주요 구성요소는 종래 두 전극(2)을 포함하는 더미스터 칩 본체(1)와 납땜부 전체 및 전선(3) 일부를 소정 형태를 갖는 케이스에 넣고 그 내부에 칩 코팅제로써 에폭시수지를 충진시키던 것을, 글레스를 고온에서 소결시켜 글레스 케이스(4)를 형성한 것이다.In addition, the second main component of the device of the present invention is to put the dummy chip main body 1 including the two electrodes (2), the soldering portion and the entire wire (3) in a case having a predetermined shape and the chip coating agent therein By filling the epoxy resin, the glass was sintered at a high temperature to form the glass case 4.
이와같이 상기 두 전극(2)을 포함하는 더미스터 칩 본체(1) 전체와 납땜부 및 전선(3) 일부에 글레스를 고온에서 소결시켜 글레스 케이스(4)를 형성하게 되면, 더미스터의 수밀성 자체가 매우 좋게 되므로 에바퍼리에터 코어 내부의 냉매 온도차에 의해 발생된 다량의 수분이 더미스터 내부로 침투되는 것 자체를 방지할 수 있어 수분 침투로 인한 고저항 발생으로 인해 발생되는 에어콘 작동 정지 현상을 미연에 방지할 수 있는 것이다.When the glass case 4 is formed by sintering the glass at a high temperature in the entire dummyster chip main body 1 including the two electrodes 2 and the soldering part and the electric wire 3, the watertightness of the dummyster itself becomes As it becomes very good, it is possible to prevent the large amount of water generated by the refrigerant temperature difference inside the evaperator core from penetrating into the dummyster itself, thus preventing the air conditioner from shutting down due to the high resistance caused by the moisture penetration. To prevent it.
이상에서 설명한 바와 같이 본 발명에 의하면, 더미스터 칩 본체의 두 전극은 금으로 형성하고, 더미스터 칩 본체와 납땜부 및 전선 일부 외측에는 글레스를 고온에서 소결시킨 글레스 케이스를 형성시켜 주므로써, 더미스터의 내부 수밀성을 향상시킬 수 있어 그 내부로의 수분 침투로 인한 고저항 발생을 방지할 수 있고, 또 전극이 금으로 되어 있으므로 칩 납땜시 이물질의 유입을 방지할 수 있어 이물질로 인한 저저항 발생을 미연에 방지할 수 있음에 따라 더미스터로 인한 에어콘의작동정지 및 불량을 미연에 방지할 수 있는 등 매우 유용한 발명인 것이다.As described above, according to the present invention, the two electrodes of the dummy chip body are formed of gold, and the glass case in which the glass is sintered at high temperature is formed on the outside of the dummy chip body, the soldering part, and the wire. It can improve the internal watertightness of Mr. and prevent the occurrence of high resistance due to moisture penetration into the inside.
