본 발명은 축전지 수납용 항온 캐비넷에 관한 것으로서, 보다 상세하게는 무선 통신 무인기지국에 설치되는 무정전 전원장치(이하 UPS)의 전원으로 사용되어지는 납축전지가 가능한한 오랫동안 제 성능을 유지하게 하고 교체주기를 감소시키기 위하여 납축전지가 일정한 범위내의 온도를 가지도록 열전소자로 내부온도를 조절할 수 있게 하여서된 캐비넷을 제공하기 위한 것이다. The present invention relates to a constant temperature cabinet for storing batteries, and more particularly, to lead-acid batteries used as a power source of an uninterruptible power supply (hereinafter, UPS) installed in a wireless communication unmanned base station to maintain their performance as long as possible and replacement cycle In order to reduce the lead-acid battery is to provide a cabinet by allowing the thermoelectric element to adjust the internal temperature to have a temperature within a certain range.

일반적으로 무선 기지국은 무선을 송수신할 수 있는 안테나와 이 안테나를 관리하는 기지국으로 구성되어 있는바, 무선 기지국에 사용되어지는 UPS는 갑작스런 전원이 차단되었을 경우에 작동되는 장비로서 내부에는 납축전지를 포함하는 것이 대부분이다. 무선기지국은 특성상 지대가 높은 곳에 설치되어 있고, 무선기지국의 건물이 외부에 노출되어 있어 여름철과 겨울철에 온도차이가 심하며 이를 통한 UPS내의 납축전지는 그 성능을 제대로 발휘하지 못하게 된다. 납축전지의 작동 온도는 25℃를 기준으로 최적의 조건을 발휘하는데 여름철에는 기온이 상승하는바, 10℃ 상승할 때마다 50%이상의 수명단축을 불러 올 수 있다. 또한 겨울철에는 기온이 하강하여 납축전지 성능이 25℃일때의 60%정도밖에 발휘하지 못하기 때문에 납축전지 용량을 큰 것을 사용하여 비용을 더 소비하여야만 한다. 또한 이러한 문제로 인하여 UPS내의 납축전지 보수 및 교체비용이 추가적으로 발생하며 온도에 따른 영향으로 배터리의 불안정한 작동을 야기하여 주전원 이상 시 기지국내의 UPS 작동 을 멈추게 할 우려가 있다. 따라서 이와 같은 문제를 해결하고자 냉장 및 온장의 원리를 이용하여 납축전지가 들어있는 캐비넷의 온도를 유지하고자 냉매를 압축 순환시키는 콤프레셔와 공기를 가열하는 히터를 설치하여 보았으나 수시로 유지 및 보수가 필요하였고 유지 및 보수에 소요되는 비용이 다대한 단점이 있었다. 또한, 이러한 장치들의 설치로 인하여 기지국의 부피 또한 커져야 하는 문제점이 있었다.In general, a wireless base station is composed of an antenna capable of transmitting and receiving radios and a base station managing the antenna. A UPS used for a wireless base station is a device operated when a sudden power failure occurs. Most of the time. The wireless base station is installed in the high ground due to its characteristics, and the building of the wireless base station is exposed to the outside, so the temperature difference between summer and winter is severe, and the lead acid battery in the UPS does not perform its performance properly. The operating temperature of lead acid battery shows the optimal condition based on 25 ℃. In summer, the temperature rises, and every 10 ℃ rise can lead to a lifespan of more than 50%. In addition, in winter, the temperature decreases, so the lead acid battery performance is only about 60% at 25 ° C. Therefore, the lead acid battery capacity must be used to increase the cost. In addition, the maintenance and replacement cost of the lead acid battery in the UPS is additionally generated due to such a problem, causing unstable operation of the battery under the influence of temperature, which may cause the UPS operation in the base station to stop when the main power fails. Therefore, to solve this problem, we tried to install a compressor that compresses and circulates the refrigerant and a heater that heats the air to maintain the temperature of the cabinet containing the lead-acid battery by using the principle of refrigeration and warming. The cost of maintenance and repair had a huge disadvantage. In addition, there is a problem that the volume of the base station must also be large due to the installation of such devices.

이에, 상기 종래 기술의 문제점을 해결하기 위하여, 본 발명은 캐비넷에 열전소자를 적용함으로써 부피의 큰 증가 없이 무선 통신 기지국의 무정전전원장치(UPS)로 사용되는 납축전지의 온도를 일정한 범위 안에서 유지시켜 납축전지 수명 연장 및 유지관리의 용이성을 제공하는 데에 그 목적이 있다.Thus, in order to solve the problems of the prior art, the present invention by applying a thermoelectric element in the cabinet to maintain the temperature of the lead acid battery used as an uninterruptible power supply (UPS) of a wireless communication base station within a certain range without a large increase in volume Its purpose is to provide extended lead-acid battery life and ease of maintenance.
