Abstract (en)

The components forming a heat exchange apparatus are integrally combined to omit piping, and the heat exchange apparatus becomes compact. The heat exchange apparatus comprises the following components: A heat exchanger section (50) in which an equipment cooling water for cooling a water cooling type equipment is heat exchanged with other cooling water to keep the equipment cooling water within a predetermined temperature range; a surge tank section (30) connected to a passage (55A-55E) of the equipment cooling water to absorb volume changes of the equipment cooling water; an ion exchanger section (60) disposed at least on a part of the passage (55A-55E) of the equipment cooling water to perform ion exchange of the equipment cooling water; and a pump (72) for circulating the equipment cooling water between the pump (72) and the water cooling type equipment. The components are accommodated in a container (20) consisting of a single vessel or a plurality of vessels (20A, 20B) integrally combined. <IMAGE>
