Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cooling system for an information processing apparatus.

[0002]

2. Description of the Related Art In a communication equipment room such as an Internet data center, in order to maintain the performance of each information processing device normally, heat generated from each information processing device is absorbed to keep the temperature of each information processing device normal. Such temperature control is performed, and a cooling device is used for this temperature control.

An example of a conventional cooling device is shown in FIG.
In the figure, a is a rack in which an information processing device b and a cooling cooler c are stored. Thus, in such a cooling device,
The indoor air is sucked and cooled by the cooling cooler c,
The cooled air is blown upward from the rack a by a fan provided in the cooling cooler c, absorbs the heat generated from each information processing device b while rising, and is discharged from the upper part into the room.

Another example of a conventional cooling device is shown in FIG. 12, in which a is a rack in which an information processing device b is stored, d is a floor-blowing type having a cooling coil e and a blower f. An air conditioner, g is a thermometer for detecting the temperature of the room in which the rack a is disposed, and h is a thermometer disposed in an air passage i formed under the floor to detect the temperature of the air blown from the blower f. is there. Thus, in such a cooling device, the cooling heat medium cooled in the outdoor unit (not shown) circulates between the outdoor unit and the cooling coil e. The air in the room is cooled by the cooling coil e and is sucked into the blower f, discharged from the blower f and introduced into the air passage i under the floor, where the air passage i
From the information processing apparatus b while absorbing the heat, and is discharged from the upper part into the room.

[0005]

In the case of the cooling device shown in FIG. 11, the capacity of the cooling cooler c is determined based on the total amount of heat generated by each information processing device b and is constant. Cannot follow the fluctuation of the heat generation amount from the information processing device b, and therefore, when the heat generation amount of the information processing device b is low,
It is supercooled and disadvantageous in energy saving. Further, since a cooling cooler c is required for each rack a, the price is high.

In the case of the cooling device shown in FIG. 12, a thermometer g detects the return temperature of the air-conditioner discharged from each rack a to control the amount of air blown by the blower f, and to control the temperature of the air blown out from the blower f by the temperature. Cooling coil e detected by meter h
The flow rate of the cooling heat medium is adjusted to control the blowing temperature of the blower f to a constant temperature. However, since the air-conditioning return temperature is the average temperature of the entire communication equipment room, the rack a having a small amount of heat is overcooled. Cooling spots occur on the surface, resulting in poor controllability. In addition, since the air passage i formed under the floor has a positive pressure, it is necessary to ensure the airtightness of the floor surface j.
The space in the communication equipment room could not be used effectively because of the need to install

[0007] In view of the above-mentioned circumstances, the present invention can save energy, is inexpensive, has good controllability without cooling spots, and needs to consider the airtightness of the floor surface.
