Claim of US Patent No. 9,832,909

1. An electronic equipment cooling device, comprising:
a rectangular parallelepiped housing in which at least one heat-generating component is disposed, the housing having a first
side wall surface and a second side wall surface that are opposite to each other, and a bottom surface;

a heat radiating side-wall fin formed on the first side wall surface of the housing;
a heat radiating bottom fin formed on the bottom surface of the housing;
a cover portion that covers the side-wall fin and the bottom fin;
a chamber forming wall that defines a chamber room between the chamber forming wall and the second side wall surface of the
housing, the chamber room being in communication with a space at an inner side of the electronic equipment cooling device,
the chamber forming wall having a coolant inlet port formed therein, through which a coolant is supplied and flows through
the chamber room to the space;

a coolant supply device that supplies the coolant through the coolant inlet port; and
a flat plate-like partition portion disposed in the chamber room so as to obliquely partition the chamber room to distribute
the coolant from the coolant inlet port toward the first side wall surface, where the side-wall fin is formed, and the bottom
surface where the bottom fin is formed, wherein

the partition portion is provided as a component independent of the housing and is detachably attached to an inside of the
chamber room, and

the partition portion has a flat plate-like surface, of which an inclination angle is adjustable.
