Abstract

PROBLEM TO BE SOLVED: To overcome the problem in the cooling method of a rack mounting information processor that sufficient cooling of a high heat generation element is difficult because the mounting space of a cooling fan can not be ensured because of compaction of the rack and that a special cooling environment, e.g. cooling water or underfloor air supply, is required when a water cooling system is employed. SOLUTION: A water cooling arrangement is provided in a compact rack, water cooling refrigerant channels are provided in a plurality of columns constituting a cabinet incorporating a water cooler, cooling refrigerant is supplied into the rack from at least one column and the cooling refrigerant, absorbed heat in the rack, is fed to at least one remaining column thus cooling each information processor. Since the cooler is incorporated in the cabinet, closed cooling can be realized without requiring any special cooling environment.

At this time, the space for mounting the cooling fan is limited by the compactness of the rack (particularly, reduction in the height direction) (FIG. 2). For this reason, the size of the cooling fan 5 that produces a required air volume cannot be mounted on the rack 6, and conversely, a cooling fan that can be mounted on the rack cannot obtain a sufficient air volume. For this reason, factors that sufficiently satisfy the cooling of the high heating element are limited. Furthermore, CPU / LSI mounted in the rack
(Large Scale Integrated circuit) and the like, the amount of heat generated is increasing year by year, making it extremely difficult to cool the device. In addition, when the water cooling method is adopted, a space for the water cooling device is required, and low-temperature air or cooling water for cooling the cooling medium in the information processing device is required. It was only a limited use in the environment.

A plurality of rack connection tubes 16 protrude from the flow path pipe 13 as shown in the figure, and an automatic opening / closing valve 15 is attached to the end thereof. This is connected to the automatic opening / closing valves 15 on the cooling medium inflow side and the outflow side of the rack 11 (the flow of the cooling medium can be either). At this time, the rack connection tube 16 is configured so as not to obstruct an interface cable or the like (not shown) connected to the rack 11.

Therefore, maintenance work of the rack becomes possible.

FIG. 4 shows an embodiment of the present invention, in which the flow pipe 13 does not need to be inside the columns 9 constituting the cabinet 7, and when the rack 11 is mounted on the cabinet 7, Any structure that allows the cooling medium to flow may be used. When a rack is mounted on the cabinet 7,
A structure in which a cooling medium flows so as to cool some racks may be used. Further, the mounting method of the water cooling device 8 may be any part or any shape as long as it is inside the cabinet 7, and it is necessary that a closed water cooling system can be used with one cabinet. (For example, a method of mounting a water cooling device such as a rack type in a cabinet).

The same applies to the use of the 16 as well, and it is not necessary to use both, the maintenance by inserting and removing the rack 11 is possible, and the leakage of the cooling medium can be prevented, and the cooling medium circulates the heat absorbed from the heating elements in the rack. Any structure can be used as long as it can be performed. Here, the reason why the tube is used is that the tube is excellent in versatility, such as prevention of corrosion by the cooling medium, extension of the tube, and free adjustment to the valve position on the rack side.

Next, the structure of the flow pipe 13 will be described. The cooling medium extruded from the cooling device 8 mounted on the cabinet 7 must flow into each rack mounted on the cabinet 7 at an equal flow rate. However, in practice, the load in the flow path pipe is constantly fluctuating, and the balance is slightly different. Therefore, a means for keeping the pressure inside the flow pipe constant is required. It is desirable to use a pressure control device or the like that automatically changes the flow rate of the cooling medium according to the differential pressure between the high pressure side and the low pressure side,
Due to the price reduction of the information processing device and the downsizing of the cooling device built in the cabinet, the use of the pressure control device is restricted to some extent. Therefore, the cooling medium is smoothly circulated by gradually narrowing the flow pipe 13 from the junction with the cooling device 8 and reducing the diameter of the pipe. Thereby, the cooling medium also flows into the rack mounted on the uppermost stage of the cabinet 7.

In the cabinet 7, a rack 14 employing a cooling method by forced air cooling equipped with a cooling fan 5 or a rack (not shown) adopting a cooling method by natural air cooling without a cooling fan can be installed. It is. At this time, the channel pipe 13 is not connected to the rack 14,
No cooling medium flows into the rack. Therefore,
The cabinet 7 according to the present invention can constitute a device without impairing the advantage that a common rack, which is commercially available, can be mounted.

FIG. 5 is a perspective view from the rear of a cabinet adopting the cooling medium flow pipe according to the present invention. The feature of this method is that the cooling medium flow pipe 13 is unified, and the cooling medium is circulated from the water cooling device 8 built in the cabinet 7 to each rack in order. At this time, the automatic opening and closing valve of the part where the rack is not mounted
15 is desirably a connectable structure as shown in the figure. This eliminates the need for extra accessories.

Further, a method is also conceivable in which the cooling medium flow pipes are individually connected to racks mounted in a cabinet, and the cooling medium is circulated to each rack (not shown). The advantage of this method is that the flow pipes are individually connected to each rack, so that the flow rate of the cooling medium can be controlled for each rack.

It is desirable that the rack has a structure that can be joined and separated when the rack is inserted and removed, and that the rack replacement operation is easy. Further, by sharing the joint between the flow path pipe and the rack, the rack mounted on the cabinet can be shared, and a device having excellent flexibility and expandability can be configured. Further, as a countermeasure against a failure, the temperature of the heating element, the temperature of the cooling medium, and the like are constantly monitored by a temperature sensor or the like.
