Description

本発明は、ラック本体の内部にサーバー冷却水の配管機構を装備したサーバーラックに関する。   The present invention relates to a server rack equipped with a server cooling water piping mechanism inside a rack body.

従来、高い冷却能力を得るために水冷方式の冷却装置を内蔵したサーバーラックが知られている。例えば、図２に示すように、特許文献１のサーバーラック５１では、縦長のラック本体５２の内部に複数のサーバー５３が格納されるとともに、サーバー冷却装置５４とその配管機構５５が設置されている。配管機構５５は給水ヘッダー５６と排水ヘッダー５７を含み、それぞれがラック本体５２の支柱５８内に配管されている。   2. Description of the Related Art Conventionally, a server rack incorporating a water cooling type cooling device is known in order to obtain a high cooling capacity. For example, as shown in FIG. 2, in the server rack 51 of Patent Document 1, a plurality of servers 53 are stored inside a vertically long rack body 52 and a server cooling device 54 and its piping mechanism 55 are installed. . The piping mechanism 55 includes a water supply header 56 and a drainage header 57, each of which is piped in a column 58 of the rack body 52.

従来のサーバーラック５１によると、給排水ヘッダー５６，５７を支柱５８に内蔵しているので、冷却用配管に妨げられることなく、ＬＡＮ配線を含む電線類をラック本体５２内に整然と配線できる利点がある。しかし、給排水ヘッダー５６，５７は、多数のサーバー５３に冷却水を供給できるように、比較的大きな貯水容積を備えているため、地震などでサーバーラック５１が揺れた場合に、冷却水の揺動によって支柱５８が長時間複雑に揺れ、ラック本体５２の耐震強度に悪影響を及ぼすという問題点があった。   According to the conventional server rack 51, since the water supply / drainage headers 56 and 57 are built in the support column 58, there is an advantage that wires including LAN wiring can be arranged in an orderly manner in the rack body 52 without being obstructed by the cooling pipe. . However, since the water supply / drainage headers 56 and 57 have a relatively large water storage volume so that the cooling water can be supplied to a large number of servers 53, when the server rack 51 is shaken due to an earthquake or the like, the cooling water swings. As a result, the column 58 swayed in a complicated manner for a long time, which adversely affects the seismic strength of the rack body 52.

本発明は、上記問題点に着目してなされたものであり、その目的は、地震などの揺れに伴う冷却水の揺動を抑え、ラック本体の耐震強度を高めることができるサーバーラックを提供することにある。   The present invention has been made paying attention to the above problems, and an object of the present invention is to provide a server rack capable of suppressing the swing of cooling water accompanying a shake such as an earthquake and increasing the seismic strength of the rack body. There is.

本発明の一実施形態を示すサーバーラックの立面図である。It is an elevation view of a server rack showing an embodiment of the present invention. 従来のサーバーラックを示す斜視図である。It is a perspective view which shows the conventional server rack.

以下、本発明の実施形態を図面に基づいて説明する。図１に示すサーバーラック１では、縦長のラック本体２の内部に、多数のサーバー３が格納されるとともに、各サーバー３に冷却水Ｃを循環させる配管機構４が設置されている。配管機構４は冷却水タンク５、給水ヘッダー６、分配管７、回収管８、排水ヘッダー９、循環ポンプ（図示略）を備えている。そして、タンク５、給水ヘッダー６および排水ヘッダー９が、サーバー３の外部で冷却水Ｃを流通可能に貯留する貯水部材として機能するようになっている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the server rack 1 shown in FIG. 1, a large number of servers 3 are stored inside a vertically long rack body 2, and a piping mechanism 4 that circulates the cooling water C is installed in each server 3. The piping mechanism 4 includes a cooling water tank 5, a water supply header 6, a distribution pipe 7, a recovery pipe 8, a drainage header 9, and a circulation pump (not shown). The tank 5, the water supply header 6, and the drainage header 9 function as a water storage member that stores the coolant C so as to be able to circulate outside the server 3.

冷却水タンク５は、ラック本体２の下部に設置され、給水ヘッダー６と排水ヘッダー９との間で冷却水Ｃを一時的に貯留する。給水ヘッダー６は、ラック本体２の第１支柱１０に内蔵され、排水ヘッダー９がラック本体２の第２支柱１１に内蔵されている。なお、第１支柱１０および第２支柱１１は、例えば、ラック本体２の４本の支柱のうち背面側の２本を使用できる。また、冷却水タンク５は、ラック本体２の上部に設置し、重力を利用して冷却水Ｃを各サーバー３に循環させることも可能である。   The cooling water tank 5 is installed in the lower part of the rack body 2 and temporarily stores the cooling water C between the water supply header 6 and the drainage header 9. The water supply header 6 is built in the first column 10 of the rack body 2, and the drainage header 9 is built in the second column 11 of the rack body 2. In addition, the 1st support | pillar 10 and the 2nd support | pillar 11 can use two on the back side among the four support | pillars of the rack main body 2, for example. In addition, the cooling water tank 5 can be installed on the upper part of the rack body 2, and the cooling water C can be circulated to each server 3 using gravity.

給水ヘッダー６および排水ヘッダー９は、支柱１０，１１の内部に直接形成することもでき、支柱１０，１１の内側に挿通したパイプによって形成することもできる。給排水ヘッダー６，９の内側には、ラック本体２の揺れに伴う冷却水Ｃの揺動を規制する複数の水流規制片１２が配設されている。冷却水タンク５の内側にも、同様に機能する水流規制片１３が配設されている。水流規制片１２，１３は楔形に形成され、基端面１２ａ，１３ａが給排水ヘッダー６，９と冷却水タンク５の内壁面に固着されている。冷却水タンク５の水流規制片１３には、冷却水Ｃを流通しやすくするための貫通孔１４が形成されている。   The water supply header 6 and the drainage header 9 can also be formed directly inside the columns 10 and 11, or can be formed by pipes inserted inside the columns 10 and 11. Inside the water supply / drainage headers 6, 9, a plurality of water flow restricting pieces 12 for restricting the swing of the cooling water C accompanying the swing of the rack body 2 are disposed. A water flow restricting piece 13 that functions in the same manner is also arranged inside the cooling water tank 5. The water flow regulating pieces 12 and 13 are formed in a wedge shape, and the base end faces 12 a and 13 a are fixed to the water supply / drainage headers 6 and 9 and the inner wall surface of the cooling water tank 5. A through hole 14 for facilitating the circulation of the cooling water C is formed in the water flow regulating piece 13 of the cooling water tank 5.

上記構成のサーバーラック１によれば、比較的多量の冷却水Ｃを貯留するタンク５、給水ヘッダー６、排水ヘッダー９に水流規制片１２，１３が配設されているので、地震などの揺れに伴う冷却水Ｃの揺動を最小限に抑えかつ早期に減衰させ、ラック本体２の耐震強度を高めることができる。また、水流規制片１２，１３を楔形に形成し、その基端面１２ａ，１３ａをヘッダー６，９およびタンク５の内壁面に固着したので、支柱１０，１１やタンク５に充分な強度を与え、必要に応じ各部材の板厚を薄くすることも可能となる。   According to the server rack 1 configured as described above, the water flow regulating pieces 12 and 13 are disposed in the tank 5, the water supply header 6, and the drainage header 9 that store a relatively large amount of cooling water C. Accordingly, the swing of the cooling water C can be minimized and attenuated quickly, and the seismic strength of the rack body 2 can be increased. Moreover, since the water flow restricting pieces 12 and 13 are formed in a wedge shape, and the base end surfaces 12a and 13a are fixed to the headers 6 and 9 and the inner wall surface of the tank 5, sufficient strength is given to the columns 10 and 11 and the tank 5, It is also possible to reduce the thickness of each member as required.

なお、本発明は上記実施形態に限定されるものではなく、水流規制片の形状や個数を変更したり、ラック上部に設置した冷却水タンクに水流規制片を設けたりするなど、発明の趣旨を逸脱しない範囲で、各部の形状並びに構成を適宜に変更して実施することも可能である。   Note that the present invention is not limited to the above-described embodiment. The shape and configuration of each part can be changed as appropriate without departing from the scope.
