ELECTRONIC INSTRUMENT AND COOLING APPARATUS FOR ELECTRONIC INSTRUMENT

WIPO Patent Application WO/2016/117098

A1

Provided are a cooling apparatus that improves the cooling capabilities for a plurality of electronic instruments and that eliminates and stabilizes unevenness of cooling capabilities as well as electronic instruments having improved cooling efficiency through immersion cooling. By providing a plurality of internal partition walls 13a-13e, 14a-14e inside a cooling tank 12 having an open space formed by a bottom wall and side walls, the open space is partitioned, forming a plurality of arranged housing portions 15aa-15dd. An electronic instrument 100 is stored in each of the housing portions. Within each of the housing portions, inflow apertures 16aa-16dd for a cooling liquid 11 are formed at a bottom portion or side surfaces of the housing portions, and outflow apertures 17aa-17ee are formed near the surface of the cooling liquid circulating in the housing portions. The electronic instruments comprise a first board 121 having a first surface on which at least one processor is disposed and a second surface opposite the first surface, a second board 122 having a third surface facing the second surface of the first board, and a flow channel 123 formed by a gap between the second surface and the third surface.
