Abstract

본 발명은 엘리베이터용 방열판의 온도제어장치 및 방법에 관한 것으로, 종래 엘리베이터를 휴식없이 계속 운행하여 방열판온도가 전력반도체가 파괴되지 않는 조건의 방열판 최고온도를 초과하면 고장처리하여 엘리베이터 운행을 정지시키는 불합리한 점을 감안하여 본 발명은 전력반도체의 스위칭시의 발열을 냉각시키는 방열판의 온도상승을 각 온도단계별로 제어함으로써 전력반도체의 열적인 파괴를 방지하고 또한 방열판의 온도가 최대치에 도달하지 않도록 적절히 제어함으로써 방열판 온도의 최대치 도달시의 운행중지로 인한 운전효율 저감을 방지하여 유운전효율을 향상시킨 것이다.The present invention relates to a temperature control device and a method for an elevator heat sink, and it is unreasonable to stop the elevator operation by troubleshooting if the heat sink temperature exceeds the maximum temperature of the heat sink under the condition that the power semiconductor is not destroyed by continuously operating the elevator without break. In view of this, the present invention controls the temperature rise of the heat sink to cool the heat generated during the switching of the power semiconductor for each temperature step, thereby preventing thermal destruction of the power semiconductor and by appropriately controlling the temperature of the heat sink to prevent the temperature from reaching the maximum value. It is to improve the operation efficiency by preventing the reduction of operation efficiency by stopping operation when the maximum heat sink temperature is reached.
