Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a cooling system for an information processing apparatus.

[0002]

2. Description of the Related Art In the prior art, a heat sink or the like is attached to a high heat generating area to increase a radiation area, and cooling is performed by blowing air to the area with a fan or the like.

[0003]

In the above-mentioned prior art, the mounting position of the cooling fan is limited due to the small size of the housing, and the distance to the heat generating portion that really needs cooling can be increased.
The cooling effect has been reduced by half. In addition, as for the high heat generation part, it is necessary to increase the size of the heat sink attached in order to enhance the cooling effect of the FAN, so that the space in the housing cannot be used effectively.

[0004]

In order to achieve the above object, in an information processing apparatus having a high heat generation part, a water jacket for cooling the heat of the part, a pipe for flowing a liquid for cooling the water jacket, and a liquid are provided. It is characterized in that the information processing apparatus is efficiently cooled by a combination of pumps for pouring the information.

[0005]

(Embodiment 1) FIG. 1 shows an embodiment of an information processing apparatus according to the present invention. The information processing device cools the high heat generation part.

[0006] The water jackets 010 and 011, a pump 001 for flowing a liquid for cooling, and a radiating pipe 020 for cooling the liquid whose temperature has passed through the water jackets 010 and 011 are cooled.
There are multiple high heat generation parts, water jacket 010,
In the case where 011 is mounted in series, the liquid whose temperature has increased due to the water jacket 010 mounted near the pump flows into the water jacket 011 mounted near the heat radiating pipe 020, and the temperature cannot be uniformly controlled. At this time, water jacket 010, 0
By arranging 11 in parallel, it becomes possible to cool a plurality of high heat generation parts uniformly. (Embodiment 2) FIG. 2 shows an embodiment of an information processing apparatus according to the present invention. The information processing apparatus includes water jackets 012, 013 for cooling a high heat generation portion, pumps 002, 003 for flowing a liquid for cooling, and a radiating pipe for cooling the liquid whose temperature has risen through the water jackets 012, 013. 021.
When there are a plurality of high heat generation parts and only one pump, it is difficult to control the flow rate of the liquid. Further, when the water jacket is mounted at a position distant from the pump, a sufficient force for flowing the liquid from the pump is required. At this time, by having a plurality of pumps 002 and 003, the flow rate of the liquid flowing into the water jackets 012 and 013 can be adjusted and strengthened, and cooling suitable for a high heat generation portion can be achieved.
It enables cooling of high heat generation parts mounted over long distances. (Embodiment 3) FIG. 3 shows an embodiment of an information processing apparatus according to the present invention. The information processing apparatus includes a water jacket 014 for cooling a high heat generation portion, a pump 004 for flowing a liquid for cooling, and a water jacket 01.
4 is composed of radiating pipes 022 and 023 for cooling the liquid whose temperature has increased through 4. If there is only one radiating pipe, the cooling effect differs depending on the mounting position in the information processing device, the installation position of the information processing device, and the like.
In this case, there is a possibility that restrictions on mounting, restrictions on installation positions, and the like may occur. At this time, by having a plurality of heat radiating pipes 022 and 023, even if one of the heat radiating pipes is installed in a place where it is difficult to radiate heat, heat can be radiated by the other heat radiating pipe. It is possible to cool a high heat generation part without restricting mounting of a pipe and installation of an information processing device. In addition, by combining the first and second embodiments, the mounting position of the high heat generation portion, the mounting position of the pump, and the mounting position of the heat radiating pipe can be freely combined to realize optimal cooling. (Embodiment 4) FIG. 4 shows an embodiment of an information processing apparatus according to the present invention. The information processing device includes water jackets 015 and 016 for cooling a high heat generation portion and a heat dissipation pipe 024, and a heat dissipation pipe 024 and a water jacket 01
5 and 016. The joint can adjust the flow rates 031 and 032 by changing the thickness of the connected tube. Joint 030 is water jacket 015,
Flow rate A03 according to high heat generation part with 016
1. The flow rate B can be adjusted, so that a plurality of high heat generation parts can be optimally cooled. When a plurality of heat radiating pipes 024 are provided, the information processing apparatus can be optimally cooled by adjusting the flow rate of the liquid to the heat radiating pipe by the cooling capacity of the heat radiating pipe.
Here, the same effect can be obtained by providing a valve or the like in the joint, other than realizing that the flow rate is changed by changing the thickness of the tube.
