Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For the machine room container 1, the length and width thereof have certain standards, for example, the outer width of the machine room container 1 is 2.438m, the inner width is 2.3m, and the depth of the space in the machine room (i.e. the dimension in the width direction of the machine room container) is generally 1.2m, when all the machine rooms are arranged along the length direction of the machine room container 1, on the one hand, two channels, respectively a cold channel and a hot channel, are formed in the width direction of the machine room container 1, and both the cold channel and the hot channel extend along the length direction of the machine room container 1, on the other hand, the width of the remaining space is only 2.3m-1.2m, which is 1.1m, and the 1.1m needs to be allocated to the cold channel and the hot channel, for example, the width of the cold channel is 0.7m, and the width of the hot channel is 0.4 m.

The research and development personnel of the application find that in the related technical scheme, an end-to-end connection scheme is adopted, namely, a heat exchange cooling device is installed on the wide side of a machine room container 1, an opening of a hot channel is arranged on the wide side of the machine room container 1 and is communicated with a hot air return opening of the heat exchange cooling device, in order to discharge hot air in the hot channel, the maximum size of the opening of the hot channel in the width direction of the machine room container 1 can only reach the same width as the width of the hot channel, however, the width of the hot channel is reduced, the cross section of the opening of the hot channel is reduced, and under the condition that the flow rate of the hot air is unchanged, the smaller the cross section area of the opening of the hot channel is, the larger the pressure of the hot air is passed, the noise is increased, and at this time, the opening of the hot channel cannot be widened to increase the sectional area, and the noise reduction cannot be performed, which is why the noise is increased when the end-to-end arrangement is adopted.

In addition, the above-mentioned end-to-end arrangement has a disadvantage: the path of the hot air traveling in the hot channel is long, usually the length of the long side of the machine room container 1, and in order to smoothly discharge the hot air, the required wind pressure is larger, which is not friendly to the selection of the fan and the service life of the fan.

In view of this, and as shown in fig. 1, 2, 3, 4, 5 and 6, the present application provides an indirect evaporative cooled container data center, which comprises a machine room container 1, a plurality of machine cabinets 2 and a heat exchange cooling device 3, wherein one side wall of the machine room container 1 is a mounting wall 10, all the machine cabinets 2 are arranged in the machine room container 1 along the length direction of the mounting wall 10, the container 1 in the machine room is divided into a cold channel 11 and a hot channel 12, the inner space of the cabinet 2 is communicated with the cold channel 11 and the hot channel 12, the opening of the cold channel 11 and the opening of the hot channel 12 are both positioned on the installation wall 10, the heat exchange cooling device 3 is installed on the installation wall 10, the heat exchange cooling device 3 is provided with an internal circulation air outlet 30 and an internal circulation air return opening 31, the internal circulation air outlet 30 is communicated with the opening of the cold channel 11, and the internal circulation air return opening 31 is communicated with the opening of the hot channel 12; the heat exchange cooling device 3 is further provided with an external circulation air inlet 32 and an external circulation air outlet 33.

In the present application, a side mounting arrangement manner is adopted, the heat exchange cooling device 3 is mounted on a side wall, that is, a mounting wall 10, of the machine room container 1, and meanwhile, an opening of the cold channel 11 and an opening of the hot channel 12 are both located on the mounting wall 10, for the hot channel 12, the reduction of the width does not affect the opening arrangement of the hot channel 12, because the opening of the hot channel 12 is arranged on the mounting wall 10, the opening size of the hot channel 12 can be enlarged in the length direction of the hot channel 12, the opening of the hot channel 12 is enlarged, for example, larger than the opening size of the traditional design or larger than the width of the hot channel 12, and further the sectional area of the opening of the hot channel 12 is enlarged, and under the condition that the flow rate of hot air is not changed, the larger the sectional area of the opening of the hot channel is, the pressure of the passing hot air is smaller, so that the noise is reduced, and the purpose of reducing noise is achieved.

Meanwhile, the modular design is adopted, the heat exchange cooling device 3 and the machine room container 1 are combined, the on-site pipeline-free construction can be realized, the on-site pipeline can be used after the installation, the construction period of on-site construction and debugging is saved, and the overall delivery time is shortened.

With reference to fig. 1 and 4, it can be seen that, with the side-mounting arrangement of the present application, since the openings of the cold channel 11 and the hot channel 12 are both located on the mounting wall 10, the path of the hot air traveling in the hot channel is inevitably reduced, and therefore, the present application is more friendly to fan selection and fan service life. Further, referring to fig. 4, the opening of the thermal channel 12 may be provided at the center of the thermal channel 12.

In the present application, in order to make the internal circulation outlet 30 communicate with the opening of the cold passageway 11, the internal circulation return air inlet 31 communicates with the opening of the hot passageway 12, and the internal circulation outlet 30 and the internal circulation return air inlet 31 are arranged in various ways:

for example, referring to fig. 1, the internal circulation air outlet 30 and the internal circulation air return opening 31 are disposed on the side wall of the heat exchange cooling device 3 connected to the mounting wall 10, that is, the internal circulation air outlet 30 is directly in butt-joint communication with the opening of the cold channel 11, and the internal circulation air return opening 31 is directly in butt-joint communication with the opening of the hot channel 12, without additional accessories for switching.

For example, referring to fig. 7 and 8, the internal circulation air outlet 30 and the internal circulation air return opening 31 are disposed on the side wall of the heat exchange cooling device 3 perpendicular to the mounting wall 10; at this moment, the internal circulation air outlet 30 and the internal circulation air return opening 31 both need to be connected through by accessories, specifically, the container data center further comprises two air pipes 4, wherein one end of one air pipe 4 is communicated with the internal circulation air outlet 30, the other end of the air pipe is communicated with the opening of the cold channel 11, one end of the other air pipe 4 is communicated with the internal circulation air return opening 31, and the other end of the air pipe is communicated with the opening of the hot channel 12.

The direct butt joint mode is adopted without accessory switching, so that the air channel can be shortest, and the wind resistance and the pressure drop are reduced; and the air pipes 4 are adopted for butt joint, so that the overall appearance is the most square.

Because there are two side walls of the heat exchange cooling device 3 perpendicular to the installation wall 10, when the internal circulation air outlet 30 and the internal circulation air return opening 31 are disposed on the side walls of the heat exchange cooling device 3 perpendicular to the installation wall 10, there are two schemes:

in one embodiment, as shown in fig. 7, the internal circulation air outlet 30 and the internal circulation air return opening 31 are located on the same side wall of the heat exchange cooling device 3. Alternatively, as shown in fig. 8, the internal circulation air outlet 30 and the internal circulation air return opening 31 are located on different side walls of the heat exchange cooling device 3.

The shape of the air duct 4 can be various, such as right-angle shape, in order to reduce the path of the cold air, so that the cold air can enter the container 1 in the machine room more quickly, and simultaneously reduce the air resistance and pressure drop, as shown in fig. 4, the air duct 4 adopts a 90-degree bent pipe.

For protecting the air duct 4 and for construction aesthetics, referring to fig. 4, the container data center further includes a protective casing 5, where the protective casing 5 is connected with the mounting wall 10 and the side wall of the heat exchange cooling device 3 and encloses to form a mounting cavity 50, and the air duct 4 is located in the mounting cavity 50.

The protective casing 5 may be integrated with the heat exchange cooling container 34 of the heat exchange cooling device 3.

Referring to fig. 1, 2 and 3, the heat exchange cooling device 3 includes a heat exchange cooling container 34, an evaporative cooling heat exchanger 35 and a fan 36, an internal circulation air outlet 30 and an internal circulation air return inlet 31 are disposed on a side wall of the heat exchange cooling container 34, an external circulation air outlet 33 is disposed on a top of the heat exchange cooling container 34, an external circulation air inlet 32 is disposed at a bottom or a side wall of the heat exchange cooling container 34, the evaporative cooling heat exchanger 35 is disposed in the heat exchange cooling container 34, an internal circulation pipeline of the evaporative cooling heat exchanger 35 communicates with the internal circulation air outlet 30 and the internal circulation air return inlet 31, an external circulation pipeline of the evaporative cooling heat exchanger 35 communicates with the external circulation air inlet 32 and the external circulation air outlet 33, and the external circulation air outlet 33 and the internal circulation air outlet 30 are both provided with the fan 36.

When the unit operates, cold air from the evaporative cooling heat exchanger 35 enters the cold channel 11 in the machine room container 1 through the internal circulation air outlet 30 after being pressurized by the fan 36, then passes through the cabinet 2 to bring out heat of equipment in the cabinet 2, and enters the internal circulation air return opening 31 after being collected by the hot channel 12 to participate in the next internal circulation.

External cold air enters from the external circulation air inlet 32, passes through the evaporative cooling heat exchanger 35 and then carries out unit heat, is discharged from the external circulation air outlet 33, and enters the external circulation air inlet 32 again after being mixed with the air to participate in the next external circulation.

As can be seen from FIG. 3, the arrangement of the internal circulation air outlet 30 at the lower part and the internal circulation air return 31 at the upper part can make the air flow organization more reasonable.
