Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heat exchange, and particularly relates to an underwater data center. BACKGROUND

[0002] A data center is a necessary component of mobile data, cloud computing and big data services. With the increase in the scale of the data center, the density of a single cabinet is also increased synchronously, and the heat generated by the corresponding device chips is also sharply increased. Therefore, the cooling problem of the data center has always been a problem that needs to be solved in this field. With the continuous progress of technology, the data center cooling technology mainly contains the following trends: end cooling equipment close to the server, fresh air direct cooling and cooling by using deep lake water or river water. The most energy-saving and highest-efficiency method is the underwater data center, which directly cools the lake water or river water without mechanical refrigeration, and can keep the data center in a stable state below 10 DEG C.

[0003] The underwater data center currently has related technologies disclosed, including an underwater data center cooling device and an underwater data center having the same. The underwater data center cooling device specifically realizes heat exchange of the data center body through a cooling pipeline containing a water pump and a heat exchange assembly. When a problem occurs and needs to be repaired, a diver needs to be salvaged to the surface for repair. The underwater data center does not have the function of directly entering the interior for repair without salvage, and does not have the function of real-time monitoring of the internal state. Similarly, technologies such as an underwater data center and an underwater data center are small data centers composed of a small number of single cabinets. The technologies do not have the functions of entering the interior for repair, automatically floating out of the water surface for repair and real-time monitoring of the internal state.

[0113] As shown in As shown in

[0114] As shown in Figures 1-3 As shown in As shown in

[0115] As shown in Figure 8 As shown in Figure 9 As shown in Figure 8 As shown in

[0116] As shown in Figures 10-11As shown, in operation, the stability of the pressure cabin as a whole is raised and lowered by the hydraulic jacking oil cylinder 2 and the lifting guide column 207, so that the pressure cabin is located below the horizontal plane, and only the openable manhole cabin 4 is located above the liquid level of the water or liquid coolant medium, so that the pressure cabin can be entered for internal maintenance without being out of water, and after being raised, the maintenance personnel can directly enter the server in the pressure cabin through the openable manhole cabin 4 to perform maintenance actions, without the need for external lifting force, which is convenient and efficient.

Specific embodiment 2:

[0118] As shown in Figures 15-22 , this specific embodiment shows a fully submerged data center. The difference between this specific embodiment and specific embodiment 1 is that in this specific embodiment, there is no openable manhole cabin 4, safety guard 402, and corresponding mounting structure as in specific embodiment 1.

Figure 20 The structure explosion diagram from the E perspective is shown. Figure 19

[0120] As shown in Figures 21-22 , in operation, the stability of the pressure cabin as a whole is raised and lowered by the hydraulic jacking oil cylinder 2 and the lifting guide column 207, so that the data center is located below the liquid level of the water or liquid coolant medium. At this time, the setting of the outer waterproof flange cover 407 and other structures can prevent water from entering the pressure cabin. When maintenance is needed, the stability of the pressure cabin as a whole is raised by the hydraulic jacking oil cylinder 2 and the lifting guide column 207, so that the maintenance non-slip plate 401 and the outer waterproof flange cover 407 are located above the liquid level, and the pressure cabin is entered through the opening of the outer waterproof flange cover 407 for maintenance.
