PURPOSE: An apparatus for keeping warm of a mobile telecommunication base station by using door closing is provided to maintain an even temperature at the base station by using an additional door and heat generated from a heat sink, thereby extending the life of the base station and preventing the trouble of the base station. CONSTITUTION: A temperature sensor senses the temperature inside the base station(10). If the temperature falls to the certain temperature, a control member operates a stepping motor(41) of a driving part, a rotating shaft(411) rotates counterclockwise, and a following shaft(42) engaging with the rotating shaft(411) rotates clockwise. At this time, a door(43) fixed at the following shaft(42) rotates at 90 degrees upward centering on the following shaft(42) to close a cooling path of the base station(10), so that the base station(10) maintains an even temperature with heat generated from a heat sink(20). If the temperature increases to the certain temperature, the control member operates the stepping motor(41), the rotating shaft(411) rotates clockwise, and the following shaft(42) engaging with the rotating shaft(411) rotates counterclockwise. At this time, the door(43) rotates at 90 degrees downward centering on the following shaft(42) to open the cooling path, so that the base station(10) maintains an even temperature by emitting heat generated from the heat sink(20) to the outside.
