PURPOSE: A water-cooled supplementary PCM(Phase Change Material) cooling system of a communication system is provided to cool off heat generated from heating units by using a PCM principle of being solidified at night and being liquified during the daytime, thereby reducing power consumption. CONSTITUTION: A copper tube(100) flows a coolant around heating units(10) in order to cool off heat generated from the heating units(10). A PCM(Phase Change Material)(200) is contacted with one side of the copper tube(100), and through a phase state, re-absorbs heat of the coolant for absorbing the heat of the heating units(10). Housings(300) include a portion of the copper tube(100) thereinto, and receive the PCM(200) so that the PCM(200) is contacted with the one side of the copper tube(100).
