本発明は、水冷方式の電子計算機システムにおける循環
水の異常監視制御方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for monitoring and controlling abnormalities in circulating water in a water-cooled computer system.
近年、電子計算機に使用されるＬＳＩの高集積化、高速
化に伴い、その発生する熱量は巨大となり、これを冷却
するための冷却方式は、空冷方式から次第に液冷方式に
移行しつつある。液冷方式にも種々の方式があるが、本
発明は水循環の水冷方式に関するものである。In recent years, as LSIs used in electronic computers have become more highly integrated and faster, the amount of heat they generate has increased, and the cooling method for cooling them is gradually shifting from air cooling to liquid cooling. Although there are various types of liquid cooling systems, the present invention relates to a water cooling system using water circulation.
［従来の技術１

冷却水異常検出器をそれぞれ示す。[Prior art 1] Fig. 2 is a system configuration block diagram of a cooling water circulation type cooling system.
Reference numeral 2 denotes a load device such as a computer, 20 a cooling water condition monitoring section, 21 a load such as a printed board of the computer, and 22 a cooling water abnormality detector.
冷却水によって冷却される電子計算機などは、冷却装置
から見て負荷装置ということができる。An electronic computer or the like that is cooled by cooling water can be called a load device from the perspective of a cooling device.
水冷却装置１内のポンプ１１によって送り出された冷却
水は、電子計算機である負荷装置２内のしｓｌ搭載プリ
ント板である負荷２１のＬＳＩを冷却して、水冷却装置
１に戻り、水冷却器１２によって冷却された後、ポンプ

ようくして、冷却水はＬＳＩの発生する熱を奪って温め
られ、水冷却器１２によって冷却されてポンプ１１によ
って送出される循環を繰り返す。The cooling water sent out by the pump 11 in the water cooling device 1 cools the LSI of the load 21, which is a printed circuit board mounted with an SL in the load device 2, which is an electronic computer, and returns to the water cooling device 1, where it is cooled by water. After being cooled by the container 12, the pump 11 sends it out again to the load device 2. In this way, the cooling water is warmed by removing the heat generated by the LSI, cooled by the water cooler 12, and then pumped out by the pump 11, repeating the cycle.
負荷装置２においては、冷却水異常検出器２２が設けら
れてあり、冷却水の水圧および水量に異常が検出される
と、冷却水状態監視部２０は電子計算機のプリント板等
である負ｖＩ２１の電源を切断する。The load device 2 is provided with a cooling water abnormality detector 22, and when an abnormality is detected in the water pressure and amount of the cooling water, the cooling water condition monitoring unit 20 detects a negative vI 21, which is a printed board of a computer, etc. Turn off the power.
また、ポンプ１１に異常が発生すると、制御部１゜はポ

出器２２がこれを検出して冷却水状態監視部２０が負荷
２１の電源を切断することになる。Further, when an abnormality occurs in the pump 11, the control unit 1° controls the pump 11 to stop. When the water pressure and the amount of water decrease due to the stop of the pump 11, the cooling water abnormality detector 22 detects this, and the cooling water condition monitoring unit 20 cuts off the power to the load 21.
［発明が解決しようとする問題点］
水循環の水冷方式において、万一水冷却装置におけるポ
ンプに障害が発生すると、負荷装置を冷却する能力がな
くなり、電子計算機を停止しなければならなくなる。[Problems to be Solved by the Invention] In the water cooling system of water circulation, if a failure occurs in the pump in the water cooling device, the ability to cool the load device will be lost and the computer will have to be shut down.
冷却装置の信頼性を上げるためには、冗長度を有する複
数のポンプを設け、現用運転中のポンプに障害が発生し
たときは、予備のポンプに切換えて運転するのが１つの
方法である。One way to increase the reliability of a cooling system is to provide a plurality of pumps with redundancy, and when a failure occurs in the currently operating pump, the operation is switched to a backup pump.
複数の水循環用ポンプを備えた水冷却装置が稼働中に、
一方のポンプに異常が発生したときは、制御部は異常な
ポンプを停止させ、休止中の他のポンプを運転させる。When a water cooling system with multiple water circulation pumps is in operation,
When an abnormality occurs in one of the pumps, the control section stops the abnormal pump and operates the other pump that is inactive.
このポンプを切換える際には、負荷装置に供給している
冷却水の水圧、水量が一旦低下した後ハンマーショック
等の異常現象が発生する。これは、休止中のポンプに起
動がかかると、水を急激に送り出そうとして圧力が上が
り、これが直ちに終息せず、圧力は下がるが下がり過ぎ
て、再び圧力が上がることを繰り返して振動的状態を起
すものである。When switching the pump, abnormal phenomena such as hammer shock occur after the water pressure and amount of cooling water supplied to the load device decreases once. This is caused by an oscillatory state in which when a paused pump is started, the pressure rises as it tries to rapidly pump out water, and this does not stop immediately, causing the pressure to drop, but then drop too much, and then rise again. It is something that causes
上記のような冷却水の異常状態は、負荷装置の発熱部を
冷却する作用には何ら影響を与えない。The abnormal state of the cooling water as described above has no effect on the cooling effect of the heat generating portion of the load device.
しかし、この冷却水の異常は負荷装置内にある冷却水異
常検出器によって検出される。However, this cooling water abnormality is detected by a cooling water abnormality detector located within the load device.
負荷装置の監視部は異常を検出すると、異常制御を行い
、負荷装置の電源切断を行ってしまうことになる。When the monitoring unit of the load device detects an abnormality, it performs abnormality control and turns off the power of the load device.
上記のような状況となっては、ポンプを複数個備え、１
つのポンプが障害を起しても、他のポンプに切換えるこ
とによって、電子計算機システムを中断することなく稼
働させるよう、ポンプの冗長運転を行っている意味がな
くなってしまうという問題点がある。In the above situation, if multiple pumps are installed, one
There is a problem in that even if one pump fails, switching to another pump eliminates the meaning of redundant operation of the pumps so that the computer system can operate without interruption.
［問題点を解決するための手段］
上記問題点は、水冷却装置が前記冷却水循環用ポンプの
切換えを行うとき、所定時間の間、負荷装置の冷却水状
態監視手段の異常検出作用をインヒビットする信号を送
出するよう構成した本発明の異常監視制御方式によって
解決される。[Means for solving the problem] The above problem is that when the water cooling device switches the cooling water circulation pump, the abnormality detection function of the cooling water condition monitoring means of the load device is inhibited for a predetermined period of time. This problem is solved by the abnormality monitoring and control system of the present invention configured to send out a signal.
［作用］
即ち、水冷却装置の制御部は、ポンプの切換えを行う際
に、負荷装置の冷却水状態監視部へ、“これからポンプ
切換えを行うから冷却水の状態に異常が発生するであろ
う”ことを知らせる信号を送出する。この信号は、ポン
プ切換えによって冷却水の水圧、水流に異常が発生する
と予想される所定期間送出する。[Operation] In other words, when switching the pump, the control unit of the water cooling device sends a message to the cooling water condition monitoring unit of the load device saying, ``Since we are going to switch the pumps, an abnormality will occur in the condition of the cooling water.'' ``It sends out a signal to let you know. This signal is sent during a predetermined period when an abnormality is expected to occur in the water pressure and water flow of the cooling water due to pump switching.
負荷装置の冷却水状態監視部は、この信号を受信してい
る間負荷装置内で発生した冷却水の異常は監視しないよ
うにする。このようにすることよって、冷却水循環用ポ
ンプの切換えは円滑に行われる。The cooling water condition monitoring unit of the load device does not monitor any abnormality in the cooling water that occurs within the load device while receiving this signal. By doing so, switching of the cooling water circulation pump is performed smoothly.
