PURPOSE: A cooling system for a communication equipment rack is provided to prevent the loss of the cool air since the cool air of the cooler is directly supplied to the inside of the communication equipment rack. CONSTITUTION: A cooler(100) is included between communication equipment racks(200). The cooler comprises a housing, a heat exchanger(121) which is formed inside the housing and generates cool air, and an operating fan(122). The driving fan blows the cool air generated from the heat exchanger to the communication equipment rack and absorbs hot air in the communication equipment rack to the inside of the housing, thereby forming circular air current. The housing comprises a cool air outlet(111) which supplies the cool air produced in the heat exchanger and a return flow outlet(113).
