TECHNICAL FIELD

The present disclosure relates to the field of computers and communications, to and in particular, to an apparatus for cooling a server cabinet and a server cabinet apparatus.

BACKGROUND

With the rapid development of computer technologies and application of large-scale Internet data centers, electronic devices are becoming more and more highly integrated, and such devices as servers may be directly installed within server cabinets. In this case, the temperature of the server cabinet directly affects the operation performance of the servers. Therefore, in an Internet data center where server cabinets are closely deployed in rows, it is a critical issue as how to cooling the server cabinets to ensure the operation performance of the servers.

As illustrated inFIG. 1, a related art provides an apparatus for cooling a server cabinet, including: a raised floor a and a support b (not illustrated inFIG. 1). The raised floor a is installed on the ground d via the support b, and a passage e is provided between the raised floor a and the ground d. The apparatus further includes an air-conditioner c implementing bottom-blowing and top-returning. In the telecommunication equipment room where a large-scale Internet data center is deployed, the air-conditioner c is positioned on the raised floor a on one side or both sides of the telecommunication equipment room, and server cabinets f are closely deployed in rows on the raised floor a in the middle of the telecommunication equipment room. The raised floor a below the air-conditioner c is provided with an air-supply outlet h, and the raised floor a between two server cabinets f is provided with a ventilation hole m. The air-conditioner c produces cold air, and the cold air is blown to the passage e between the raised floor a and the ground d via the air-supply outlet h on the raised floor below the air-conditioner c, and then the cold air is blown from the ventilation hole m on the raised floor a to the server cabinets f, thereby cooling the server cabinets E

During the implementation of the present disclosure, the inventors find that the related art has at least the following problems:

Since air-conditioners are generally deployed at one side or both sides of a telecommunication equipment room, in a large-scale Internet data center, some server cabinets in the telecommunication equipment room may not sufficiently cooled. In addition, there is a large space between the raised floor and the ground, and therefore cold air in the passage is not fully used, resulting in a waste of resources.

DETAILED DESCRIPTION

To make the objectives, technical solutions, and advantages of the present disclosure clearer, embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

An embodiment of the present disclosure provides an apparatus for cooling a server cabinet. The apparatus may be applied to a server cabinet apparatus as illustrated inFIG. 2orFIG. 3, and the server cabinet apparatus includes an apparatus n for cooling a server cabinet and a server cabinet4. The apparatus n is positioned below the server cabinet4.

The apparatus n includes: a bracket1, a heat-exchange device2, and an air ducting device3.

The bracket1is positioned below one or a plurality of server cabinets4, the heat-exchange device2is installed on a side surface of the bracket1, the air-ducting device3is installed in the bracket1, the heat-exchange device2and the air-ducting device3are parallelly arranged, the heat-exchange device2cools hot air produced by the server cabinet4to obtain cold air, and the air-ducting device3blows the cold air to the server cabinet4to cool the server cabinet4.

The bracket1below each of the server cabinets4is installed with the heat-exchange device2and the air-ducting device3, and the heat-exchange device2and the air-ducting device3are close to the server cabinet4above the bracket L Therefore, each of the server cabinets4is cooled by the corresponding heat-exchange device2and the air-ducting device3, thereby preventing the problem in the related art that the servers deployed in the middle of the telecommunication equipment room fail to be effectively cooled and resources are wasted because the air-conditioners are deployed in both sides of the telecommunication equipment room.

One server cabinet may correspond to one bracket1or a plurality of server cabinets4may correspond to a bracket1. When the bracket1is sufficiently large, the plurality of server cabinets4may be simultaneously positioned on one bracket1, thereby saving space.

The heat-exchange device2and the bracket1may be assembled together in a thread connection manner. The thread connection manner includes a bolt connection manner, a screw connection manner, or a double-head bolt connection manner.

For example, the heat-exchange device2and the bracket1may be assembled together in the bolt connection manner, or may be assembled together in the screw connection manner, or may be assembled together in the double-head bolt connection manner.

When the heat-exchange device2needs inspection and repair, the heat-exchange device2may be separated from the bracket1by loosing the bolt or screw connected therebetween, such that the heat-exchange device2is removed, thereby facilitating inspection and repair of the heat-exchange device2.

The air-ducting device3includes a blower31and a first air-ducting plate32, where the heat-exchange device2, the blower31, and the first air-ducting plate32are sequentially arranged parallelly, the blower31is positioned below the server cabinet4, and the first air-ducting plate32is positioned on an outer side of the server cabinet4.

Referring toFIG. 2, an inner side surface of the first air-ducting plate32is a concave curved surface, the inner side surface facing towards the blower31; or referring toFIG. 3, the first air-ducting plate32is a flat plate, which is perpendicularly installed in the bracket, and comprises a surface facing towards the blower31.

Preferably, the inner side surface of the first air-ducting plate32is a concave curved surface.

If the inner side surface of the first air-ducting plate32is a concave curved surface, the blower31blows the cold air to the first air-ducting plate32, and under the action of the concave curved surface of the first air-ducting plate32, a movement direction of the cold air may be change such that the cold air reaches the server cabinet4conveniently.

The blower31is positioned between the heat-exchange device2and the first air-ducting plate32.

As illustrated inFIG. 4, the bracket may include a first bracket11and a second bracket.12, one side of the first bracket11is connected to the other side of the second bracket12, the server cabinet4is positioned on the first bracket11, the heat-exchange device2is installed on the other side of the first bracket11, the blower31is installed, in the first bracket11, and the first air-ducting plate32is installed in the second bracket12.

One server cabinet4may be positioned on one first bracket11. When the first bracket11is sufficiently large, a plurality of server cabinets4may be simultaneously positioned on one first bracket11, thereby saving space. For example,FIG. 4illustrates a scenario where one server cabinet4is positioned on the first bracket11.

The server cabinet4produces hot air and blows the produced hot air to the heat-exchange device2, and the heat-exchange device2cools the hot air to obtain cold air, and blows the cold air to the blower31, such that the cold air is blown by the blower31to the first air-ducting plate32. The inner side surface of the first air-ducting plate32is a concave curved surface, and the inner side surface faces towards the blower31. Under the action of the concave curved surface of the first air-ducting plate32, the movement direction of the cold air is changed such that the cold air reaches the server cabinet4above the first bracket11thereby cooling the server cabinet4. Alternatively, the first air-ducting plate32is a flat plate, and the first air-ducting plate32is perpendicularly installed in the bracket1; and under blockage of the first air-ducting plate32, the cold air is blown to the server cabinet4above the first bracket11, thereby cooling the server cabinet4.

The first bracket11below the server cabinet4is installed with the heat-exchange device2and the blower31, and the second bracket12connected to the first bracket11is installed with the first air-ducting plate32, such that the cold air reaches the server cabinet4, thereby effectively cooling the server cabinet4.

The blower31installed in the first bracket11is capable of blowing the cold air to the first air-ducting plate32, such that the server cabinet4is cooled. Therefore, the first bracket11implements an air blowing function in addition to the function of supporting the server cabinet4.

When the bracket1is formed by the first bracket11and the second bracket12, manufacture and transportation of the bracket11is more convenient. To be specific, both the first bracket11and the second bracket12may be separately manufactured and transported, and assembled onsite to form the bracket1, thereby achieving modularized assembling of the bracket1.
