Abstract

PURPOSE:To reduce the consumption of power and the generation of noise by providing a fan box and a driving part to drive a fan for cooling. CONSTITUTION:A fan box 3 is provided with plural additive fans 5 so as to be fitted to an enclosure 1 for an information processor while being exchanged with the cover of the enclosure 1, and the driving part is provided to drive the additive fans 5 while being interlocked with a basic part fan 4. In this case, when the basic part fan 4 is operated, the additive fans 5 are simultaneously operated as well, and air is sucked from slits 7 and exhausted from the bottom of the enclosure 1 to the outside (air current 12). Thus, the quantity of the air current 12 can be increased for cooling as necessary and the heat generating source of the enclosure 1 can be strongly cooled. Therefore, the consumption of power and the generation of noise can be reduced in a normal state, and cost can be reduced.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for an information processing device, and more particularly to a cooling device for an information processing device for increasing its cooling capacity in accordance with the installation conditions of the information processing device.

0002

[Prior Art] Conventional cooling methods for information processing equipment (equipment) take into consideration the worst case combination of all conditions, such as ambient temperature, installation conditions such as near a wall, and operating conditions such as heat generation. All the cooling fans necessary for this purpose are fixedly built into the housing of the information processing device.

0003

[Problems to be Solved by the Invention] As mentioned above, conventional cooling systems for information processing devices are designed assuming the worst case among combinations of conditions such as installation conditions and operating conditions. All necessary cooling fans are fixedly built into the housing of the information processing equipment, so if the equipment is not used under the worst conditions, it consumes excess power, generates a lot of noise, and costs more. It has the disadvantage of being high.

0004

[Means for Solving the Problems] A cooling device for an information processing device according to the present invention includes a fan box that has a plurality of cooling fans and is attached to a housing of the information processing device in exchange for a cover;
and a drive unit that drives the cooling fan in conjunction with the drive of the information processing device.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 shows a state before the additional fan box of this embodiment is attached to the information processing apparatus, and shows how the information processing apparatus is used under normal installation and operating conditions.

At this time, as shown in FIG. 2, a back cover 2 is attached to the back of the housing 1, and three basic fans 4 fixedly provided at the lower part of the inside of the housing 1 are installed on the back of the housing 1. The inside of the housing 1 is cooled by rotating the . That is, when the base fan 4 rotates, air is sucked in through the slit 6 provided in the back cover 2 and discharged from the bottom surface of the housing 1 (air flow 11). This airflow 11 cools heat sources such as cards and power supply units (not shown) installed in the housing 1.

FIG. 1 shows the state after the additional fan box of this embodiment is attached to the information processing device, and is used when the information processing device is used under harsher conditions than normal installation and operating conditions. It shows the aspect. FIG. 3 is a circuit diagram showing means for supplying power to the additional fan in the embodiment of FIG.

In FIG. 1, an additional fan box 3
is attached to the back of the housing 1 after removing the back cover 2 (see FIG. 2). Inside Fun Box 3,
Three additional fans 5 are mounted, and slits 7 are provided in the back plate thereof. As shown in FIG. 3, the additional fan 5 is connected by a power supply cable 13 so as to operate in conjunction with the basic fan 4, and is connected to the common power supply part 1.
Power is supplied from 4.

With this configuration, when the basic fan 4 is operated, the additional fan 5 is also operated at the same time.
Air is sucked in through the slit 7 and discharged from the bottom of the housing 1 (air flow 12). This air flow 12 has a larger air volume than the air flow 11 in FIG. 2 by the amount of the additional fan 5, and powerfully cools heat sources such as cards and power supply units installed in the housing 1.

[0011]

As explained above, the cooling device for an information processing device of the present invention includes a fan box that has a plurality of additional fans and is attached to the casing in place of the cover of the casing of the information processing device; By providing a drive unit that drives an additional fan in conjunction with the basic fan installed in the device, the volume of airflow for cooling can be increased as necessary to powerfully cool the heat source inside the housing. Therefore, there is an effect that power consumption and noise generation in a normal state can be reduced, and costs can be reduced.
