Abstract

PURPOSE:To make equipment compact and raise its capacity and efficiency, by providing a partition wall which divides a heat exchange section and a space on a main machine into two chambers and cooling the chambers by a first and a second fans of different capacity. CONSTITUTION:A partition wall 10 is provided along an enclosed casing so that the space in the casing except for the space of a main machine 3 is divided into two portions and heat exchangers 12a, 12b are constructed. A first fan 15a circulates a coolant through the heat exchanger 12a, an opening 16a along the casing, a first bearing 14a, an opening 17a at the bottom of equipment and a second bearing 14b. A second fan 15b circulates a coolant through the other heat exchnger 12b, an opening 16b inside the partition wall 10 and the main machine 3 so that some of the coolant flows through a lower opening 17b. Since such a cooling system is provided, efficiency is heightened and the reduction in the size of the equipment and the increase in its capacity are enabled.
