본 발명은 배전반, 제어반 등에 부착시켜서 반내(반내(盤內) 온도제어를 행하는 반응 열교환기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reaction heat exchanger which is attached to a switchboard, a control panel, or the like to perform temperature control in a panel.

제1도에 나타내는 바와 같이, 반 내측의 수열공간(1)과 반 외측의 방열공간( 2)을 방열부재(3)에 의해 구획함과 동시에, 반 내의 공기를 상기 수열공간(1)을 통하여 순환시키는 반내 팬(4)과, 상기 방열공간(3)에 외기를 순환시키는 반외 팬(5)을 구비한 반용 열교환기가 종래부터 알려져 있다.As shown in Fig. 1, the heat receiving space 1 on the inside of the van and the heat radiating space 2 on the outside of the van are partitioned by the heat radiating member 3, and the air in the van is passed through the heat receiving space 1. The half heat exchanger provided with the half inside fan 4 which circulates, and the half outside fan 5 which circulates outside air in the said heat radiating space 3 is known conventionally.

상기와 같은 종래의 반용 열교환기는, 반내 냉각필요시에는 수동에 의해 연속운전되도록 되어 있 는 것이 보통이다. 그러나 이 경우에는, 반내온도가 저하하였을 때에도 반내 팬(4)이나 반외 팬(5)의 운전이 계속되는 에너지의 낭비가 생기기 쉽다. 또 반외 팬(5)에 의해 상시 흡인되는 외기중의 먼지에 의해, 반외 팬(5)의 필터(6)나 방열부재(3)가 더러워지기 쉬우며, 메인터넌스(maintenance) 사이클을 짧게 하지 않으면 않되는 문제가 있었다.In the conventional half heat exchanger as described above, when it is necessary to cool the inside of the chamber, it is common to continuously operate it manually. However, in this case, even when the half-chamber temperature falls, it is easy to generate | occur | produce the energy which the operation | movement of the half-bed fan 4 and the half-board fan 5 continues. In addition, the filter 6 and the heat radiating member 3 of the half outside fan 5 are easily polluted by the dust in the outside air which is always drawn by the half outside fan 5, and the maintenance cycle must be shortened. Had a problem.

이 때문에, 반내온도를 온도 검지기로 감시하여 온도제어운전을 행하도록 한 것도 있으며, 이 경우에는 제3도의 플로우 시이트에 나타내는 바와같이, 검지된 반내온도가 설정온도를 초과하면, 반내 팬(4)과 반외 팬을 동시에 온 오프(on off)제어하는 것이 보통이었다. 그러나, 배전반, 제어반 등의 반내 온도는, 반내 팬(4)이 정지한 상태에 있어서는 발열이 큰 기기의 주변에서 국부적으로 고온으로 되기 쉽우며, 온도 검지기의 부착위치에 따라서는 냉각개시가 늦어질 염려가 있었다.For this reason, in some cases, the temperature inside the panel is monitored by a temperature detector to perform a temperature control operation. In this case, as shown in the flow sheet of FIG. 3, when the detected half temperature exceeds the set temperature, the half inside fan 4 It was common to turn on and off fans at the same time. However, the inside temperature of the switchboard, the control panel, etc., tends to be locally high in the vicinity of the high heat generation apparatus when the inside fan 4 is stopped, and the cooling start may be delayed depending on the attachment position of the temperature detector. There was concern.

또, 연속운전하는 것이나 온도제어하는 것의 어느 것에 있어서도, 오일미스트나 먼지가 없는 반내 공기를 순환시키는 반내 팬(4)에 의해, 오일미스트나 먼지가 있는 외기를 순환시키는 반외 팬(5)의 쪽이, 필터(6)의 저항도 영향을 주어 빨리 고장난다는 문제가 있었다.In addition, in either the continuous operation or the temperature control, the half-board fan 5 which circulates the outside air with oil mist and dust by the inside fan 4 which circulates the inside air without oil mist or dust. This also affects the resistance of the filter 6 and causes a problem of rapid failure.

본 발명은 상기 문제점을 해결하여, 에너지의 낭비를 감소시킬 수 있으며, 메인터넌스 사이클을 연장할 수 있으며, 그리고 반내 온도가 국부적으로 고온으로 될 수 없는 반용 열교환기를 제공하기 위하여 이루어진 것이다.The present invention has been made to solve the above problems, to reduce the waste of energy, to extend the maintenance cycle, and to provide a half-use heat exchanger, the temperature in the half can not be locally high temperature.

상기 문제를 해결하기 위하여 이루어진 본 발명은, 반 내측의 수열공간과 반외측의 방열공간을 방열부재에 의해 구획함과 동시에, 반 내의 공기를 상기 수열공간을 통하여 순환시키는 반내 팬과, 외기를 흡인하여 상기 방열공간으로 순환시키는 반외 팬을 구비한 반용열 교환기에 있어서, 반내 팬을 상시 운전하는 한편, 반외 팬은 반내 온도가 설정온도를 초과하였을 때에만 운전하도록 한 것을 특징으로 하는 것이다.In order to solve the above problems, the present invention divides the heat-receiving space inside the vane and the heat-radiating space outside the vane by a heat dissipation member, and sucks the outside fan and the outside air to circulate air in the van through the heat-receiving space. In the half-use heat exchanger having the half-heat fan circulated to the heat dissipation space, the half-vehicle fan is always operated while the half-vehicle fan is operated only when the half-temperature fan exceeds the set temperature.

본 발명의 반응 열교환기는, 반내 팬을 상시 운전하도록 한 것이므로, 반내 온도가 국부적으로 고온으로 되는 것이 방지된다. 또 반내 공기는 먼지를 포함하고 있지 않으므로, 반내 팬을 상시 운전하여도 방열부재가 더러워질 염려가 적다. 더욱이 반내 온도가 설정온도를 초과하였을 때에만 반외팬을 운전하도록 하였으므로, 반내를 설정온도를 이하로 유지할 수 있는 데에다, 에너지의 낭비를 감소시킬 수 있으며, 필터의 오염도 감소시킬 수 있으므로 메인터넌스 사이클을 연장시킬 수 있다. 또한 반외 팬의 수명이 연장되므로, 반용 열교환기의 제품전체로서의 수명도 연장할 수 있다.Since the reaction heat exchanger of the present invention is to operate the fan in the chamber at all times, the temperature in the chamber is prevented from becoming locally high. In addition, since the air in the board does not contain dust, there is little fear that the heat radiation member will be dirty even if the fan in the board is always operated. Furthermore, the half-board fan is operated only when the temperature inside the panel exceeds the set temperature, so that the inside of the panel can be kept below the set temperature, energy consumption can be reduced, and filter pollution can be reduced, so that maintenance cycle can be performed. Can be extended. In addition, since the life of the half-side fan is extended, the lifetime of the half-heat exchanger as a whole product can be extended.

이하에 본 발명을 실시예에 의해서 더욱 상세하게 설명한다.The present invention will be described in more detail with reference to the following Examples.

본 발명에 있어서도 기기의 구성은 제1도에 나타내는 것과 동일하지만, 제2도의 플로우 시이트에 나타내는 바와 같이, 시작과 동시에 반내 팬(4)을 상시 운전하고, 반 내의 공기를 수열공간(1)을 통하여 순환시킨다. 이로써 반 내의 공기는 교반되어서 반내 온도는 균일화되고, 국부적인 고온이 해소된다.Also in the present invention, the configuration of the apparatus is the same as that shown in FIG. 1, but as shown in the flow sheet of FIG. Circulate through. As a result, the air in the van is agitated so that the temperature in the van is made uniform and local high temperatures are eliminated.

그리고 반내온도가 설정온도를 초과하였을 때에는 반외 팬(5)의 운전을 개시하고, 필터(6)를 통하여 외기를 흡입하여 방열공간(2)으로 순환시킨다. 이때, 방열부재(3)를 통하여 수열공간(1)과 방열공간(2)의 사이에서 열교환이 행해지고, 반내온도는 점차 저하된다. 그리고 반내온도가 설정온도 보다도 어느 온도 (D)만큼 저하하면, 반내 팬(4)의 운전을 계속한채로 반외 팬(5)의 운전을 정지시킨다.When the half inner temperature exceeds the set temperature, the operation of the half outside fan 5 is started, and the outside air is sucked through the filter 6 and circulated to the heat dissipation space 2. At this time, heat exchange is performed between the heat receiving space 1 and the heat radiating space 2 via the heat radiating member 3, and the half-temperature is gradually lowered. When the half-board temperature falls by a certain temperature (D) from the set temperature, the half-bed fan 5 is stopped while the half-pan fan 4 continues to operate.

이와 같이, 반 내의 공기는 반내 팬(4)에 의해서 상시 교반되어 있으므로, 반내온도를 검출하는 온도 검지기는 반드시 반 내에 설치할 필요는 없으며, 상기 수열공간(1)내에 설치할 수도 있다.In this way, since the air in the van is always stirred by the pan 4 in the van, the temperature detector for detecting the vane temperature does not necessarily need to be installed in the van, and may be provided in the hydrothermal space 1.

이상 설명한 바와 같이, 본 발명에 의하면 반내 팬을 상시 운전하므로, 공기순환에 의한 기기의 냉각효과를 얻을 수 있다. 또 반 내는 상시 교반되어서 온도가 균일화되고, 반내온도가 국부적으로 고온으로 되는 것을 방지할 수 있음과 동시에, 반내온도의 검지를 보다 높은 정밀도로 행할 수 있다. 나아가서는, 반용 열교환기의 제품전체의 수명연장을 도모할 수 있다. 그리고, 반내 공기를 먼지를 포함하고 있지 않으므로, 반내 팬을 상시 운전하여도 방열부재가 더러워질 염려는 적다.As described above, according to the present invention, the fan in the board is always operated, so that the cooling effect of the device by air circulation can be obtained. In addition, the inside of the board is always stirred to uniformize the temperature, prevent the inside temperature of the board from being locally high, and detect the inside temperature at a higher precision. Furthermore, the life of the whole product of the half heat exchanger can be extended. In addition, since the air in the van does not contain dust, there is little fear that the heat dissipation member will be dirty even if the fan in the van is operated at all times.

또, 반내온도가 설정온도를 초과하였을 때에만 반외 팬을 운전하도록 하였으므로, 반 내를 설정온도 이하로 유지할 수 있는 데에만, 에너지의 낭비를 감소시킬 수 있다. 또한 반외 팬의 운전시간을 단축시킬 수 있으므로, 방열부재나 필터의 오염을 감소시킬 수 있으며, 메인터넌스 사이클의 연장 및 반외 팬의 수명연장을 도모할 수 있다. 이상과 같이, 본 발명은 종래의 문제점을 해결한 반용 열교환기로서, 실용적 가치가 높은 것이다.In addition, since the half-board fan is operated only when the half-chamber temperature exceeds the set temperature, the waste of energy can be reduced only when the inside of the half-pan can be kept below the set temperature. In addition, since the operation time of the halfway fan can be shortened, contamination of the heat dissipation member or filter can be reduced, and the maintenance cycle can be extended and the lifespan of the halfway fan can be extended. As mentioned above, this invention is a half heat exchanger which solved the conventional problem, and is high in practical value.
