본 발명은 보조히터에 관한 것으로, 더욱 상세하게는 하나의 어셈블리로된 발열수단을 단일체로 된 편평 튜브의 내부에 삽입 설치하기 때문에 조립 능률을 향상시킴과 아울러 발열수단에어 발생된 열은 일정한 간격을 유지하고 있는 다수의 발열핀들 사이를 통해 외부로 빨리 전달되도록 한 보조히터에 관한 것이다.The present invention relates to an auxiliary heater, and more particularly, since the heating means of one assembly is inserted into and installed inside a flat tube of a single unit, the assembly efficiency is improved and the heat generated by the heating means is maintained at regular intervals. It relates to an auxiliary heater to be quickly delivered to the outside through a plurality of heating fins to maintain.

일반적으로 차량의 난방용 열교환기는 엔진을 냉각시키고 난 후의 고온의 엔진 냉각수를 열원으로 하여 공기를 가열하고, 이를 차량 실내로 공급한다.In general, a heat exchanger for heating a vehicle heats air by using high temperature engine coolant after cooling the engine as a heat source, and supplies the same to a vehicle interior.

그런데, 이러한 난방용 열교환기에서는 엔진에 시동을 건 시동 초기에는 효과적으로 난방을 수행할 수 없는 한계가 있었다.However, in such a heat exchanger for heating, there is a limit in that heating cannot be effectively performed at the initial stage of starting the engine.

즉, 시동 초기에 엔진이 충분히 가열되지 않아 난방용 열교환기의 열원인 엔진 냉각수를 이용하는 데에는 한계가 있었기 때문이다.That is, there is a limit in using the engine coolant that is a heat source of the heat exchanger for heating because the engine is not sufficiently heated at the start of the start.

또한, 상기 엔진 냉각수를 열원으로 하는 난방장치에 있어서는 차량의 엔진의 고성능화함에 따라 난방 성능이 부족한 경우가 자주 발생하여 이러한 난방 불량 문제는 더욱 대두되고 있다.In addition, in the heating apparatus using the engine cooling water as a heat source, the heating performance is often insufficient due to the high performance of the engine of the vehicle, and this problem of poor heating is more serious.

이렇게 부족한 난방 성능을 보완하기 위하여 난방용 열교환기에 보조히터를 장착하는 방법이 시도되고 있다. In order to compensate for the insufficient heating performance, a method of mounting an auxiliary heater in a heat exchanger for heating has been attempted.                         

이러한 보조히터의 일 예로서 전기적으로 발열하는 발열체가 있는데, 이는 온도 증가에 따라 저항이 증대되어 정온도 특성을 가지므로 화재의 위험성이 적고, 온도조절 특성을 갖고 있어서 최근 차량에의 적용이 매우 활발히 진행되고 있다.An example of such an auxiliary heater is a heating element that generates heat electrically, which has a constant temperature characteristic with increased resistance as the temperature increases, so there is little risk of fire and temperature control characteristics, so the application to a vehicle is very active recently. It's going on.

종래 기술에 의한 난방용 열교환기로서 일본 공개특허번호 특개평10-288493호가 있다.As a heat exchanger for heating according to the prior art, there is JP-A-10-288493.

이 기술은 도 1 및 도 2에 도시된 바와 같이, 온수 입구측 탱크(1)와, 온수 출구측 탱크(2)와, 이 양 탱크(1)(2)의 사이에 설치된 열교환용 코어부(3)를 가지고 있다.As shown in Figs. 1 and 2, the technique includes a core part for heat exchange between the hot water inlet side tank 1, the hot water outlet side tank 2, and the two tanks 1 and 2, Have 3)

상기 열교환용 코어부(3)의 일부 부위에 편평 튜브(6)의 대용으로 전기 발열체(9)가 설치되어 있다.An electric heating element 9 is provided at a portion of the heat exchange core 3 in place of the flat tube 6.

한편, 부호 12,13은 스테인리스와 같은 내식성에 우수한 금속재료로 된 체결부재이고, 열교환용 코어부(3)의 공기 입구측의 면 및 공기 출구측면의 양쪽에 배치된다.On the other hand, reference numerals 12 and 13 are fastening members made of a metal material excellent in corrosion resistance such as stainless steel, and are disposed on both of the air inlet side and the air outlet side of the heat exchange core portion 3.

상기 체결부재(12)(13)는 그 양단을 절곡된 형상의 후크부를 가지고 있다.The fastening members 12 and 13 have hook portions having bent shapes at both ends thereof.

상기 후크부를 상하의 사이드 블레이드(8a)(8b)의 길이 방향으로의 중앙부에 형성된 계지홈부(8c)(8d)에 걸려져 있다.The hook portion is caught by the locking groove portions 8c and 8d formed in the center portion in the longitudinal direction of the upper and lower side blades 8a and 8b.

상기 체결부재(12)(13)의 장착에 의해 전기 발열체(9)를 2장의 지지판(10)(11)의 사이에 압접 지지되는 것이다.By mounting the fastening members 12 and 13, the electric heating element 9 is pressed and supported between the two support plates 10 and 11.

그런데, 상기와 같이 구성된 종래 기술에 따르면, 다음과 같은 문제점이 있었다. However, according to the prior art configured as described above, there were the following problems.

In the prior art, the electric heating element 9 has a plurality of heat generating elements 9a interposed between the terminal plates 9b and 9c, and then the terminal plates 9b and 9c and the heat generating elements 9a stacked in a three-layer structure. Since it was configured to be stacked in a total of five layers by interposing between the two support plates 10, 11, the assembly process is very cumbersome, there is a problem that productivity is lowered.
