Description

Server cooling device and its fan module

technical field

The invention relates to a heat dissipation device, in particular to a heat dissipation device for a server and a fan module thereof.

Background technique

As a node of the network, the server stores and processes more than 80% of the data and information in the network, so it is also called the soul of the network. Network terminal equipment, such as computers in homes and businesses, accessing the Internet, obtaining information, and communicating with the outside world must go through the server.

A server is a high-performance computer that provides various services for client computers. Its high performance is mainly reflected in high-speed computing capabilities, long-term reliable operation, and powerful external data throughput. Therefore, the server is running A lot of heat is generated in the process, especially with the advancement of information technology, the role of the network is becoming more and more obvious, and people have higher and higher requirements for the data processing capacity and security of the server, which leads to the increasing heat of the server. Dissipating the heat inside the server to ensure its normal operation has become one of the important issues in the industry.

In order to dissipate the heat generated by the server during operation, the industry usually installs a fan module consisting of several fans in the chassis of the server to maintain the internal temperature of the server within a normal range. However, servers as the foundation of the information industry often need to be updated. Every time a server is replaced, no matter whether the old fan module can meet the requirements of the new server in terms of performance, it will be different from the internal specification structure of the new server. If they do not match, they need to be replaced in succession, resulting in great waste. This is not only inconsistent with the current national policy of energy conservation and emission reduction, but also increases the cost of server replacement.

Contents of the invention

In view of this, it is necessary to provide a reusable cooling device and fan module for servers.

A fan module for a server, comprising a fixing frame and at least one fan arranged on the fixing frame, the fixing frame is used to fix the at least one fan on the outside of the server, an airflow channel is formed in the fixing frame, the The air flow channel communicates with the inside of the server, and the at least one fan dissipates heat to the inside of the server through the air flow channel in the fixed frame. The fixed frame is surrounded by a fixed plate, a mounting plate and an air guide plate. When the fixing frame is fixed to the server, the at least one fan is installed on the installation plate, and the air deflector guides the airflow generated by the at least one fan.

The above-mentioned fan module fixes the fan on the outside of the server through the fixing frame. The fan module is not affected by the specific specifications and structures inside the server. When the server is replaced, the fan module can be directly applied to the new server without replacement, thereby Effectively save the cost of server replacement.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and embodiments.

As shown in FIG. 1 , a heat dissipation device 100 in a preferred embodiment of the present invention includes two servers 20 and a fan module 10 , and the fan module 10 is installed on the outside of the two servers 20 to simultaneously perform cooling on the two servers 20 Heat dissipation. The two servers 20 can be servers of various specifications, and in this embodiment, each server 20 is a standard 1U (1U=4.445cm) server, and the two servers 20 are stacked up and down. In actual use, one server 20 may be configured with one fan module 10 , or two or more servers 20 may share one fan module 10 .

Referring to FIG. 2 , the fan module 10 includes a fixing frame 11 and four fans 12 mounted on the fixing frame 11 . The server 20 includes a square top board 21 and four side boards 22 vertically extending outward from the top board 21 . The fixing frame 11 is fixed on the front side boards 22 of the two servers 20 .

The fixing frame 11 is roughly in the shape of a hollow triangular prism. The fixing frame 11 includes a fixing plate 111 , a mounting plate 112 and a wind deflecting plate 113 connected in pairs. The fixing plate 111 is perpendicular to the mounting plate 112, the fixing plate 111 is facing the side plates 22 of the two servers 20 and is fixed on the side plates 22, the fixing plate 111 is along the length direction of the side plates 22 of the two servers extend. The fixed plate 111 is provided with four ventilation holes 114, and the four ventilation holes 114 are arranged at equal intervals along the extending direction of the fixed plate 111, and each ventilation hole 114 is connected with the inside of the two servers 20 for air flow out. Alternatively, the height of the ventilation hole 114 is greater than the thickness of any server 20 to cover the upper and lower servers 20 . The mounting plate 112 is connected to the top of the fixing plate 111 and is flush with the top plate 21 of the server 20 above. The mounting plate 112 is provided with four through holes 115, and the through holes 115 are perpendicular to the ventilation holes. 114 , and are arranged at equal intervals along the length direction of the mounting plate 112 , and the through holes 115 communicate with the ventilation holes 114 . The four fans 12 are installed on the mounting plate 112 , and each fan 12 faces a through hole 115 on the mounting plate 112 . The wind deflector 113 is inclined, and it is connected between the bottom end of the fixing plate 111 and the end of the mounting plate 112 away from the server 20. The wind deflecting plate 113 is used to guide the ventilation holes 114 and The air flow through the through hole 115 of the mounting plate 112 . The inside of the fixed frame 11 is provided with a partition 116 between two adjacent fans 12, thereby dividing the inside of the fixed frame 11 into four airflow passages 117 arranged along the length direction of the side plate 22 of the server 20, so, When any one fan 12 breaks down in the four fans 12, the fan 12 that breaks down and the adjacent normal operation fan 12 will not form an airflow path through the inside of the fixed frame 11, thereby ensuring the normal operation of the fan. 12 still dissipates heat inside the two servers 20 through their corresponding through holes 115 and ventilation holes 114 .

When the fan module 10 is in use, the fan 12 communicates with the inside of the server 20 through the fixing frame 11, and the fan 12 connects the two servers 20 through the corresponding through holes 115 and ventilation holes 114 on the fixing frame 11. The hot air flow is drawn into the external environment, thereby forming a negative pressure inside the server 20, and the cold air flow in the external environment enters the interior of the two servers 20 under the action of the negative pressure to dissipate heat from the two servers 20, thereby maintaining the internal pressure of the server 20. The temperature remained stable within the normal range.

As shown in FIG. 3 , a plurality of fan modules 10 can be simply stacked together for heat dissipation of multiple servers 20 stacked on each other. The plurality of fan modules 10 are arranged along the stacking direction of the plurality of servers 20, and adjacent Among the two fan modules 10, a gap 30 between the air deflector 113 of the upper fan module 10 and the mounting plate 112 of the lower fan module 10 is just used to accommodate the fan of the lower fan module 10. 12.

Compared with the prior art, since the fan module 10 is placed outside the server 20, it is not affected by the specific specifications and structures inside the server 20. When the server 20 is replaced, the fan module 10 can be directly applied without replacement. For the new server 20, the fan module 10 can be reused, which effectively saves the replacement cost of the server 20. In addition, the fan module 10 placed outside the server 20 can use a fan 12 with a larger size because it is not limited by the internal space of the server 20, thereby providing a stronger convection airflow to the server 20 to improve the heat dissipation effect; moreover, for The maintenance and replacement of a single fan 12 can be directly disassembled from the fixing frame 11 of the server 20 without disassembling the server 20 , thus greatly simplifying the maintenance and replacement process of each fan 12 of the fan module 10 .
