ELECTRONIC DEVICE

摘要

An electronic device capable of efficiently cooling an integrated circuit device disposed heat-exchangeably on a cold plate (16). In a single case (3) , there is housed a circuit board (5) on which an integrated circuit device requiring a measure against the heat generated is mounted. The electronic device comprises the cold plate (16) attached to the integrated circuit devi ce so as to transfer the heat from the integrated circuit device, a heat exchanger (11) for cooling the brine which is heated by the cold plate (16) and circulated therein, a fan casing (39) constituting a wind passage in the opening made in one face of the case (3) and leading from a blower fan (14) to the heat exchanger (11), a reservoir tank (26) and a pump (15) disposed in order of mention in the flow of the brine from the heat exchanger (11) to th e cold plate (16), and brine passages (23) and (23) of a straight shape arrang ed in the cold plate (16) and forming at least one pair of going and returning passages.
