Detailed Description
Fig. 1 shows the indirect evaporative cooling system of modular data center of an embodiment of the present invention, including the indirect evaporative cooling system body 1 (hereinafter referred to as body 1) of modular data center and the fence structure 2 arranged on the body 1, the body 1 includes a closed gas exchange space surrounded by a plurality of enclosing plates 10 and an indirect evaporative cooling unit, and the indirect evaporative cooling unit includes an outdoor fan 14 and an indoor fan 15.
Specifically, the gas exchange space includes a heat exchange space 11, an air inlet 12 and an air outlet 13, the air inlet 12 is connected to an indoor air inlet 121 of the modular data center (not shown) and an outdoor air inlet 120 of the modular data center is connected to the outdoor environment, and the air outlet 13 is connected to the modular data center. The outdoor fan 14 is located above the outside of the gas exchange space and the indoor fan 15 is located in the gas exchange space.
As shown in fig. 1 to 4, when the indirect evaporative cooling unit operates, the indoor fan 15 drives the airflow 41 to enter the heat exchange space 11 from the outdoor air inlet 120 and the indoor air inlet 121, and after the airflow sequentially passes through the heat exchange core (not shown in the figure) and the evaporator (not shown in the figure) along the horizontal direction, the temperature of the gas decreases, and as shown in fig. 4, the generated low-temperature gas 42 enters the modular data center from the air outlet 13. The outdoor fan 14 drives the air flow 41 to enter the heat exchange space 11 and then flow upwards through a condensing part (not shown in the figure), and the condensed gas releases heat to generate high-temperature gas 43 which is discharged out of the gas exchange space from the outdoor fan 14.
As shown in fig. 1, the enclosure structure 2 is located at the periphery of the outdoor fan 14, and encloses a heat dissipation space 3 guiding a flow path of the high-temperature gas 43 discharged from the outdoor fan 14 upward at the top of the body 1.
The enclosure structure 2 includes a fixed closure 20 attached to the body 1. For convenience of installation, the fixed shroud 20 may be formed by splicing a plurality of single fixed shrouds, or may be formed integrally. The fixed enclosing plate 20 and the body 1 are fixedly connected reliably, including but not limited to bolt connection, welding, interference fit connection and the like.
As shown in fig. 1-4, at least one dirt discharging groove 200 is formed on the fixed enclosing plate 20, a cover body covering the dirt discharging groove 200 is arranged on the dirt discharging groove 200, and the cover body is openably and closably arranged on the dirt discharging groove 200. Because of heat dissipation space 3 is open air environment, the blowdown groove can be used to the maintainer in time discharge the snow or the ponding in heat dissipation space 1 when sleet weather to avoid snow and ponding to influence the normal operating of outdoor fan 14. It can be understood that the existence of the dirt discharging groove 200 can cause the high temperature gas 43 in the heat dissipating space 3 to flow out from the dirt discharging groove 200, so that an openable cover body can be additionally arranged on the outer surface of the dirt discharging groove 200, and when the accumulated snow or accumulated water does not need to be cleaned, the cover body covers the dirt discharging groove 200 to prevent the high temperature gas 43 from flowing out from the dirt discharging groove 200. In some embodiments, the cover may be connected to the fixed shroud 20 by bolts, or the fixed shroud 20 and the cover may be connected by fasteners, or one side of the cover and the fixed shroud 20 may be designed as an integral structure, and the other side of the cover opposite to the cover may be connected to the fixed shroud 20 by bolts or fasteners. The fixed boarding 20 is further provided with drain holes 201 which are distributed at intervals and can be used for draining water in the heat dissipation space 3 without artificial interference by utilizing the self weight of water flow in rainy seasons so as to prevent serious water accumulation.
In order to facilitate the maintenance personnel to go in and out of the heat dissipation space 3 to maintain the outdoor fan 14, at least one maintenance door 202 is further arranged on the fixed enclosing plate 20. An access passage (not shown) connected to the access door 202 is provided in the heat dissipation space 3. The maintenance passageway can set up between outdoor fan 14, makes things convenient for the maintainer to remove between outdoor fan 14 and overhauls.
As shown in fig. 1, the fencing structure 2 further includes a support frame 203 provided on the fixed closure 20. The supporting frame 203 comprises a transverse reinforcing rib and a vertical reinforcing rib which are arranged on the fixed enclosing plate 20, and understandably, the transverse reinforcing rib can limit the deformation of the fixed enclosing plate 20 in the horizontal direction; the vertical reinforcing ribs can limit the deformation of the fixed shroud 20 in the vertical direction. The provision of transverse and vertical reinforcing ribs can increase the rigidity and strength of the fixed shroud 20. In order to enhance the overall stability of the enclosure structure 2 and prevent the enclosure structure from toppling in the direction inside the heat dissipation space 3 when being subjected to an external force, such as strong external airflow impact, the enclosure structure 2 may further include at least one diagonal support member 204, one end of the diagonal support member 204 is disposed on the support frame 203, and the other end of the diagonal support member 204 is disposed on the main body 1. Specifically, the other end of the diagonal brace 204 may be fixed to the bottom of the outdoor fan 14 as shown in fig. 3, or the other end of the diagonal brace 204 may be directly fixed to the top surface of the body 1.
As shown in fig. 2, when the main body 1 has no enclosure structure 2, the high temperature gas 43 discharged from the outdoor fan 14 flows upward and both sides simultaneously, and a portion of the high temperature gas 43 flowing out from the sides enters the outdoor air inlet 120, so as to form an air flow circulation 40, and the existence of the air flow circulation 40 reversely guides the high temperature gas 43 to enter the outdoor air inlet 120. The gas flowing in from the indoor air inlet 121 is indoor high-temperature gas in the modular data center, in this case, the temperature of the gas entering the heat exchange space 11 is too high due to the introduction of the high-temperature gas 43 from the outdoor air inlet 120, which affects the power efficiency of the indirect evaporative cooling unit. In severe cases, when the temperature of the gas flowing through the indirect evaporative cooling unit exceeds the working allowable temperature of the cooling unit design, the short circuit phenomenon of the unit can be caused.
As shown in fig. 3, after the enclosure structure 2 is installed on the main body 1, the flow direction of the high-temperature gas 43 exhausted by the outdoor fan 14 is restricted to be upward, so that the phenomenon that the high-temperature gas 43 flows to two side surfaces and enters the outdoor air inlet 120 again is avoided.
The above-mentioned only be the embodiment of the present invention, not consequently the restriction of the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transform made of the content of the specification and the attached drawings, or directly or indirectly use in other relevant technical fields, all including in the same way the patent protection scope of the present invention.
