Description

Technical Field

[0001] The present invention relates to the field of Internet technologies, and particularly to a modular server cabinet. Background Art

[0002] With the rapid development of the Internet, the number of network servers has also increased rapidly. Server cabinets are used to place servers for unified management. In addition to servers, accessories such as switches, UPSs, monitoring hosts, and routers usually need to be configured in the cabinets. These accessories and servers can be collectively referred to as network devices.

[0003] In addition, a power distribution module for power distribution to network devices and a coolant circulation module need to be installed in the cabinet. At the same time, according to the actual needs of users, a battery module, a fire protection module, etc. may also need to be installed in the cabinet. The power distribution module, the battery module, and the fire protection module constitute auxiliary devices for ensuring the normal operation of network devices.

[0004] Currently, in the prior art, server cabinets are usually manufactured according to specific usage scenarios. Network devices and auxiliary devices are configured in the same cabinet. For different usage scenarios, a very large number of different server cabinets need to be manufactured. However, the adaptability of a single cabinet is not strong, and it is not flexible to use. It is very difficult to coordinate changes or flexibly combine according to different usage scenarios, which is not conducive to large-scale cluster use, and it is also very difficult to meet the requirements of high security redundancy levels and cannot ensure the long-term reliable operation of servers. Summary of the Invention

[0005] The purpose of the present invention is to provide a modular server cabinet with good coordination, strong adaptability, and convenient and flexible combination.

[0006] To achieve the above purpose, the modular server cabinet in the present invention adopts the following technical solutions:

Detailed Embodiments

[0029] Embodiment 1 of the modular server cabinet in the present invention is as follows Figure 1 shown, including a first type of auxiliary equipment cabinet 100 and a network equipment cabinet 200. The first type of auxiliary equipment cabinet 100 and the network equipment cabinet 200 are arranged left and right and connected together side by side to form a "one-to-one" type of modular server cabinet. The network equipment cabinet 200 in the present invention has a standard cabinet width, and the first type of auxiliary equipment cabinet 100 has a half-cabinet width.

[0030] Network equipment is provided in the network equipment cabinet 200. The network equipment includes servers 202 and accessory devices 209. Specifically, a liquid cooling box 201 is provided in the network equipment cabinet 200. The liquid cooling box 201 is used to contain coolant. A plurality of servers 202 are vertically arranged side by side and installed in the liquid cooling box 201. The placement direction of the servers 202 is horizontal. During use, all or part of the servers 202 are immersed in the coolant. To facilitate the circulation and heat dissipation of the coolant, thereby improving the heat dissipation effect on the servers 202, a coolant outlet 205 is provided at the top of the liquid cooling box 201, and a coolant inlet 206 is provided at the bottom of the liquid cooling box 201.

[0031] In addition, to avoid coolant loss caused by coolant volatilization and the influence of the volatilized working medium on the air cleanliness in the cabinet, a sealing cover plate 203 is provided at the top of the liquid cooling box 201. The sealing cover plate 203 is used to completely enclose the servers 202 and the coolant in the liquid cooling box 201.

[0032] In addition, to facilitate wiring and maintenance, a port expansion board 204 is also installed in the network equipment cabinet 200. As shown in Figure 2 shown, the port expansion board 204 is located outside the liquid cooling box 201. A plurality of expansion ports are provided on the port expansion board 204. Each expansion port is respectively connected in one-to-one correspondence with a plurality of ports on the server 202 through a cable (not shown in the figure). In this way, when connecting and maintaining the server 202, there is no need to open the sealing cover plate 203, and it can be directly carried out on the port expansion board 204.

[0033] In addition, to facilitate the lifting of the server 202 for installation, a lifting device 207 is provided above the liquid cooling box 201 in the network equipment cabinet 200. The lifting device 207 can be telescoped up and down and moved left and right, and can meet the lifting requirements of the server 202.

[0034] An independent rack 208 is provided above the liquid cooling box 201 in the network device cabinet 200, and the independent rack 208 is arranged above the lifting device 207. The accessory device 209 is installed on the independent rack 208. The accessory device 209 includes at least one of a switch, an uninterruptible power supply (UPS), a monitoring host, a router, and a disk array, and is configured according to customer requirements. The accessory devices 209 all belong to devices that cannot be cooled by being immersed in the coolant. In order to facilitate heat dissipation for them, a refrigeration device capable of blowing cold air is also installed on the independent rack 208. The refrigeration device is located below the accessory device 209, and a filter element for purifying gas is provided in the refrigeration device (not shown in the figure). Therefore, the refrigeration device in this embodiment is a refrigeration and purification integrated machine 210.

[0035] The refrigeration and purification integrated machine 210 can use compression refrigeration or thermoelectric refrigeration. The refrigeration and purification integrated machine 210 can blow cold air to lower the temperature inside the cabinet, thereby dissipating heat from the accessory device 209. Therefore, the space where the refrigeration and purification integrated machine 210 and the accessory device 209 are located forms an air-cooled space. In fact, the internal space of the network device cabinet 200 is divided into a liquid-cooled space and an air-cooled space by the sealing cover plate 203, and the internal space of the liquid cooling box 201 is the liquid-cooled space.

[0036] The refrigeration and purification integrated machine 210 can also purify the air. This is considered because although the coolant in the liquid cooling box 201 has been sealed by the sealing cover plate 203, for a very small amount of leakage during maintenance operations, the refrigeration and purification integrated machine 210 can filter and adsorb it, thereby ensuring the cleanliness of the air in the air-cooled space and preventing the volatile working medium from depositing on the accessory device 209 and affecting its normal operation.

[0037] As Figure 1 and Figure 3 shown, an auxiliary equipment cabinet 100 is provided with auxiliary equipment. The auxiliary equipment includes a power distribution module 101 and a battery module 102 for power supply and distribution to network devices. The power distribution module 101 is arranged above the battery module 102. The auxiliary equipment further includes a fire protection module 103 and a coolant circulation module 104. The fire protection module 103 is arranged above the coolant circulation module 104, and the power distribution module 101 and the battery module 102 are located on the front side of the fire protection module 103 and the coolant circulation module 104.

[0038] The coolant circulation module 104 includes a heat exchanger 1041 which is used to connect to an external cold source through an external circulation pipeline 1044. The external cold source can be various cooling devices such as a dry cooler, a cooling tower, a refrigerator, etc. The coolant inlet 206 and the coolant outlet 205 on the liquid cooling box 201 are connected to the heat exchanger 1041 through an internal circulation pipeline 1042, and a pump 1043 is arranged on the internal circulation pipeline 1042. Under the action of the pump 1043, the coolant in the liquid cooling box 201 enters the internal circulation pipeline 1042 through the coolant outlet 205, and after being cooled by the heat exchanger 1041, it is input into the liquid cooling box 201 again through the coolant inlet 206 to form a cycle.

[0039] The reason for setting the coolant inlet 206 at the bottom of the liquid cooling box 201 and the coolant outlet 205 at the top of the liquid cooling box 201 is that the heat dissipated by the server 202 is mainly concentrated in the upper part of the coolant. Therefore, continuously pumping out the upper coolant and then replenishing it from the lower part after cooling is beneficial to improving the circulating cooling effect.

[0040] In this embodiment, the modular server cabinet is formed by connecting a type-one auxiliary equipment cabinet 100 and a network equipment cabinet 200 side by side. In actual production, multiple network equipment cabinets 200 and multiple type-one auxiliary equipment cabinets 100 can be manufactured separately, and then according to different usage scenarios, select appropriate network equipment cabinets 200 and type-one auxiliary equipment cabinets 100 to connect side by side, and make coordinated changes and flexible combinations, which improves the coordination and adaptability of the cabinet and greatly facilitates the construction of a new computer room. At the same time, due to the side-by-side connection of multiple cabinets, it can also be applied to the upgrade and transformation of an old computer room. The modular server cabinet can operate independently with a single cabinet or be used in a large-scale cluster, which is beneficial to the popularization and practical application of the liquid cooling method.
