This application claims priority to Chinese Patent Application No. 201510674815.2 filed on Oct. 19, 2015, the contents of which are incorporated by reference herein.
The subject matter herein generally relates to cooling systems, and more particularly to a cooling system for a data center.
In order to allow electronics to function properly, data centers may need to adjust cooling based on ambient temperature. More and more data centers use cold air from outside to dissipate heat.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
Each sidewall 13 is equipped with a first check valve 131, the air outside the server cabinet 10 can pass through the first check valve 131 to flow into the server cabinet 10, and the air inside the server cabinet 10 is blocked from flowing out of the server cabinet 10 by the first check valve 131. Each sidewall 13 is equipped with a filter plate 132 located above the first check valve 131. The filter plate 132 is configured to prevent dust from entering the server cabinet 10. A plurality of filter holes 135 are defined in the filter plate 132 to allow the air to pass through. The rear wall 14 is equipped with a plurality of second check valves 142. The second check valve 142 allows the air inside the server cabinet 10 to flow out from the server cabinet 10, and the second check valve 142 can block the air outside the server cabinet 10 from flowing into the server cabinet 10.
The rack 16 includes a bracket 161, the bracket 161 is equipped with a plurality of third check valves 163. The third check valves 163 are configured to allow air from the second receiving space 22 to pass through into the first receiving space 21, and the third check valves 163 prevent the air from the first receiving space 21 from flowing into the second receiving space 22.
The cooling module 50 includes a plurality of first cooling fans 51, a plurality of second cooling fans 52 and two heat-exchange equipments 55. The first cooling fans 51 are secured on the rear wall 14 and can drive the air flow to the second check valves 142. The second cooling fans 52 are received in the second receiving space 22. The second cooling fans 52 are secured on the bracket 161 and can drive the air flow to the third check valves 163. The two heat-exchange equipments 55 are respectively secured on the two ends of the rack 16 close to the side walls 13. The heat-exchange equipment 55 can drive the air flow of the second receiving space 22 to enter the first receiving space 21.
When the predetermined environmental condition is suitable or reached (low temperature, low humidity, little dust, and so on) for air flow to cool the server cabinet 10, the first cooling fans 51 and the heat-exchange equipments 55 are turned on, the second cooling fans 52 are turned off. The cold air flow outside the server cabinet 10 passes the first check valves 131 and the air vents 145 to flow into the first receiving space 21. Then the cold air flow passes between the electronic equipment of the rack 16, and absorbs the heat of the electronic equipment to become hot air flow, and then flows into the second receiving space 22. The first cooling fans 51 drive the hot air flow through the second check valves 142 to go out of the server cabinet 10 to cool the electronic equipment quickly.
When the server cabinet 10 needs to be cooled, the first cooling fans 51 and the heat-exchange equipments 55 are turned on, the second cooling fans 52 are turned off. The cold air flow from outside the server cabinet 10 passes through the first check valves 131 and the air vents 145 to flow into the first receiving space 21. Then the cold air flow passes between the electronic equipment of the rack 16, and absorbs the heat of the electronic equipment to become hot air flow, and flows into the second receiving space 22. The first cooling fans 51 drive the hot air flow through the second check valves 142 out of the server cabinet 10 to cool the electronic equipment quickly.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a cooling system for data center. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
