Abstract
Description
本發明係關於一種機櫃液冷系統,特別係關於一種包含多個伺服器的機櫃液冷系統。 The present invention relates to a cabinet liquid cooling system, in particular to a cabinet liquid cooling system including multiple servers.
一般來說,由於機櫃中的多個伺服器會產生大量的熱,因此通常會使用液冷技術來冷卻機櫃中的這些伺服器。在這樣的情況中,冷卻液會流動於伺服器以及如冷卻分配單元(Cooling Distribution Unit,CDU)之液冷裝置之間以對伺服器進行散熱。並且,伺服器的入口及出口分別會透過接頭設置有流管以使冷卻液能流進及流出伺服器。 Generally speaking, since multiple servers in a rack generate a lot of heat, liquid cooling technology is usually used to cool these servers in a rack. In such a situation, the coolant flows between the server and a liquid cooling device such as a cooling distribution unit (CDU) to dissipate heat from the server. Moreover, the inlet and outlet of the server are respectively provided with flow pipes through the joints so that the cooling liquid can flow into and out of the server.
然,當其中一個伺服器需要進行維修而從機櫃被移除時,機櫃中其他繼續運作的伺服器便會有更多的冷卻液流入,這使得設置於其他繼續運作的伺服器之入口的接頭承受過大的壓力。如此一來,冷卻液便有可能會從接頭漏出。 However, when one of the servers needs to be repaired and removed from the rack, the remaining servers in the rack will have more coolant flowing in, which puts excessive pressure on the connectors located at the inlets of the remaining servers. As a result, coolant may leak from the joint.
本發明在於提供一種機櫃液冷系統以防止冷卻液在部分伺服器進行維修而被移除時從設置在其他繼續運作的伺服器之入口的接頭漏出。 The present invention provides a cabinet liquid cooling system to prevent cooling liquid from leaking from joints provided at the inlets of other servers that continue to operate when some servers are removed for maintenance.
本發明一實施例所揭露之機櫃液冷系統包含多個伺 服器、一液冷裝置、一第一分岐管、一第二分岐管、至少一溢流管以及至少一控制閥。每一伺服器包含一第一入口以及一第一出口。第一入口連接第一出口。液冷裝置包含一第二入口以及一第二出口。第二入口連接第二出口。第二入口連接第一出口。第二出口連接第一入口。第一分岐管以及第二分岐管連通每一伺服器以及液冷裝置。每一伺服器的第一入口以及第一出口分別連接第一分岐管以及第二分岐管。液冷裝置的第二入口以及第二出口分別連接第二分岐管以及第一分岐管。至少一溢流管的相對兩端分別設置於第一分岐管及第二分岐管。伺服器、液冷裝置及至少一溢流管透過第一分岐管及第二分岐管以並聯的方式彼此連接。至少一控制閥包含一第一閥瓣、一第二閥瓣、一受推件以及一彈性件。第一閥瓣以及第二閥瓣可轉動地設置於至少一溢流管中。彈性件的相對兩端分別固定於至少一溢流管及受推件。彈性件用以推抵受推件而使得受推件抵靠於第一閥瓣以及第二閥瓣之間而阻斷至少一溢流管與伺服器及液冷裝置的連通。當至少一控制閥承受一臨界壓力時,受推件克服彈性件的彈力而遠離第一閥瓣以及第二閥瓣,進而使至少一溢流管連通於伺服器及液冷裝置。 The cabinet liquid cooling system disclosed in an embodiment of the present invention includes multiple server, a liquid cooling device, a first branch pipe, a second branch pipe, at least one overflow pipe and at least one control valve. Each server includes a first entrance and a first exit. The first inlet is connected to the first outlet. The liquid cooling device includes a second inlet and a second outlet. The second inlet is connected to the second outlet. The second inlet is connected to the first outlet. The second outlet is connected to the first inlet. The first branch pipe and the second branch pipe communicate with each server and the liquid cooling device. The first inlet and the first outlet of each server are respectively connected to the first branch pipe and the second branch pipe. The second inlet and the second outlet of the liquid cooling device are respectively connected to the second branch pipe and the first branch pipe. The opposite ends of the at least one overflow pipe are respectively arranged on the first branch pipe and the second branch pipe. The server, the liquid cooling device and at least one overflow pipe are connected in parallel through the first branch pipe and the second branch pipe. At least one control valve includes a first valve disc, a second valve disc, a pushed member and an elastic member. The first valve flap and the second valve flap are rotatably arranged in at least one overflow pipe. The opposite ends of the elastic member are respectively fixed to at least one overflow pipe and the pushed member. The elastic member is used to push against the pushed member so that the pushed member leans against between the first valve flap and the second valve flap to block the communication between the at least one overflow pipe and the server and the liquid cooling device. When at least one control valve bears a critical pressure, the pushed member overcomes the elastic force of the elastic member and moves away from the first valve flap and the second valve flap, so that at least one overflow pipe communicates with the server and the liquid cooling device.
根據上述實施例所揭露之機櫃液冷系統,伺服器、液冷裝置及溢流管透過第一分岐管及第二分岐管以並聯的方式彼此連通,且控制閥設置於溢流管中。因此,當伺服器皆不需要進行維修時,控制閥得以關閉而防止伺服器的冷卻作業因冷卻液流至溢流管中而受到影響。當部分伺服器需要進行維修而被移除時, 控制閥得以開啟而使冷卻液流至溢流管中。如此一來,溢流管便能分擔原本要流進被移除的伺服器的冷卻液,而降低設置在其他繼續運作的伺服器之第一入口的接頭所承受的壓力,進而防止冷卻液從接頭漏出。 According to the cabinet liquid cooling system disclosed in the above embodiments, the server, the liquid cooling device, and the overflow pipe communicate with each other in parallel through the first branch pipe and the second branch pipe, and the control valve is disposed in the overflow pipe. Therefore, when the servers do not need to be maintained, the control valve can be closed to prevent the cooling operation of the servers from being affected by the coolant flowing into the overflow pipe. When part of the server is removed for repair, The control valve is opened allowing coolant to flow into the overflow pipe. In this way, the overflow pipe can share the cooling liquid that originally flowed into the removed server, and reduce the pressure on the joints disposed at the first inlets of other servers that continue to operate, thereby preventing the cooling liquid from leaking from the joints.
此外,當控制閥承受臨界壓力時,受推件會克服彈性件的彈力而遠離第一閥瓣以及第二閥瓣,進而使溢流管連通於伺服器及液冷裝置。因此,透過受推件、彈性件、第一閥瓣以及第二閥瓣之間的配合,無須透過維修人員的操作便能調整控制閥的開啟或關閉,這提升了根據本發明的機櫃液冷系統使用上的便利性。 In addition, when the control valve is subjected to a critical pressure, the pushed member will overcome the elastic force of the elastic member and move away from the first valve disc and the second valve disc, thereby making the overflow pipe communicate with the servo and the liquid cooling device. Therefore, through the cooperation between the pushed member, the elastic member, the first valve disc and the second valve disc, the opening or closing of the control valve can be adjusted without the operation of the maintenance personnel, which improves the convenience in use of the cabinet liquid cooling system of the present invention.

In this embodiment, the
根據上述實施例所揭露之機櫃液冷系統,伺服器、液冷裝置及溢流管透過第一分岐管及第二分岐管以並聯的方式彼此連通,且控制閥設置於溢流管中。因此,當伺服器皆不需要進行維修時,控制閥得以關閉而防止伺服器的冷卻作業因冷卻液流至溢流管中而受到影響。當部分伺服器需要進行維修而被移除時,控制閥得以開啟而使冷卻液流至溢流管中。如此一來,溢流管便能分擔原本要流進被移除的伺服器的冷卻液,而降低設置在其他繼續運作的伺服器之第一入口的接頭所承受的壓力,進而防止冷卻液從接頭漏出。 According to the cabinet liquid cooling system disclosed in the above embodiments, the server, the liquid cooling device, and the overflow pipe communicate with each other in parallel through the first branch pipe and the second branch pipe, and the control valve is disposed in the overflow pipe. Therefore, when the servers do not need to be maintained, the control valve can be closed to prevent the cooling operation of the servers from being affected by the coolant flowing into the overflow pipe. When part of the servo is removed for maintenance, the control valve is opened to allow coolant to flow into the overflow pipe. In this way, the overflow pipe can share the cooling liquid that originally flowed into the removed server, and reduce the pressure on the joints disposed at the first inlets of other servers that continue to operate, thereby preventing the cooling liquid from leaking from the joints.
此外,當控制閥承受臨界壓力時,受推件會克服彈性件的彈力而遠離第一閥瓣以及第二閥瓣,進而使溢流管連通於伺服器及液冷裝置。因此,透過受推件、彈性件、第一閥瓣以及第二閥瓣之間的配合,無須透過維修人員的操作便能調整控制閥的開啟或關閉,這提升了根據本發明的機櫃液冷系統使用上的便利性。 In addition, when the control valve is subjected to a critical pressure, the pushed member will overcome the elastic force of the elastic member and move away from the first valve disc and the second valve disc, thereby making the overflow pipe communicate with the servo and the liquid cooling device. Therefore, through the cooperation between the pushed member, the elastic member, the first valve disc and the second valve disc, the opening or closing of the control valve can be adjusted without the operation of the maintenance personnel, which improves the convenience in use of the cabinet liquid cooling system of the present invention.
