PURPOSE: A cooling apparatus for a print board assembly is provided to enhance the cooling efficiency without using a blow fan in an outdoor system difficult to employ a forced cooling method using the blow fan, thereby saving energy consumption due to the blow fan as well as removing fan noise. CONSTITUTION: The print board assembly(14) having circuit chips(16) is installed on a copper plate(10). A heat pipe(12) connected to the circuit chip(16) is mounted on one side of the copper plate(10), and a heat sink(20) having radiator pins(22) is mounted on the other side of the copper plate(10). At this time, a flat side of the heat sink(20) is positioned within a rack body(18) and the radiator pins(22) is positioned outside the rack body(18). Therefore, heat generated from the circuit chip(16) is transferred to the copper plate(10) through the heat pipe(12).
