Description

Server device and fan module thereof

Technical Field

The present invention relates to a server device, and more particularly, to a server device having a fan module.

Background

With the continuous innovation of technology, the volume of the electronic components in the system is gradually miniaturized, and the working efficiency is gradually enhanced, so that if the heat generated by the electronic components cannot be effectively dissipated, the high temperature of the heat will cause the electronic components in the system to crash, thereby shortening the product life of the electronic components. Generally, a plurality of fans are installed in a chassis to enhance the air flow inside the chassis, so as to dissipate the heat generated during the operation of the system.

However, when the fans output the heat dissipation airflow to enter the chassis, if there is a gap with a certain width between the fans, the airflow of the fans will leave the chassis from the gap during the circulation process in the chassis, thereby reducing the heat dissipation performance of the fans to the system.

Therefore, how to solve the problems of the conventional heat dissipation system has become a technical issue to be solved in the industry.

Furthermore, the definitions of the above-mentioned words in commonly used dictionaries should be interpreted as having a meaning consistent with the context of the present invention. Unless specifically defined otherwise, these terms are not to be interpreted in an idealized or overly formal sense.

Fig. 1 is a perspective view of a server apparatus 10 according to an embodiment of the present invention. Fig. 2 is an exploded view of the server device 10 and the fan module 200 of fig. 1. Fig. 3 is a schematic view of the server apparatus 10 viewed from above according to the embodiment of the present invention. As shown in fig. 1 to 3, the server apparatus 10 includes a chassis 100 and a fan module 200. The housing 100 has a bottom plate 110 and a plurality of side plates 120. The side plates 120 are located on different sides of the bottom plate 110, and the side plates 120 all extend in a common direction (e.g., Z axis). The side plates 120 jointly surround the bottom plate 110, so that the bottom plate 110 and the side plates 120 jointly define a receiving groove 140. One side plate 120 has an opening 130 capable of communicating with the receiving groove 140.

In the embodiment, the casing 100 has a motherboard 150, a plurality of card slots 160, and a plurality of interface cards 170. The main board 150 is located in the receiving groove 140 and disposed on the bottom plate 110. The card slots 160 are electrically connected to the motherboard 150 and are arranged on the motherboard 150 along an arrangement direction (e.g., X axis). The interface cards 170 are inserted into the card slots 160, respectively, and electrically connected to the motherboard 150. The long axis direction (e.g., Y-axis) of each interface card 170 is orthogonal or at least transverse to the alignment direction (e.g., X-axis) and orthogonal or at least transverse to the common direction (e.g., Z-axis). For example, the card slot 160 is a PCI-e slot and the interface card 170 is a stand-alone display card or a random access memory, although the utility model is not limited thereto.

The fan module 200 includes two fan devices 210 and a wind shielding member 400. The two fan units 210 are fixed on the opening 130 and arranged along the arrangement direction (such as the X axis). The wind shielding member 400 is fixed to the opening 130 and directly sandwiched between the fan units 210. Each fan unit 210 outputs airflow from the opening 130 to the interface card 170 towards the receiving slot 140. The wind-shielding member 400 is used to block the airflow in the accommodating groove 140 from flowing out of the chassis 100 from between the fan devices 210.

Thus, in order to match the distribution range of a specific number of interface cards 170, the clamping of the wind-shielding member 400 between the fan units 210 can increase the working area of the fan units 210 compared to the fan units connected directly in parallel, so as to provide heat dissipation for the interface cards 170.

It should be understood that, in the present embodiment, the fan module 200 completely covers the opening 130 of the chassis 100 to prevent the airflow from flowing out of the chassis 100 through the opening 130.

The two first engaging members 430 are oppositely located in the box groove 420, and the two first engaging members 430 are connected to the box body 410 and detachably engaged with the first engaging interface 132 and the third engaging interface (not shown), respectively. The outer sides 411 of the case 410 directly contact the outer surface 211 of each fan unit 210, respectively.

Each fan device 210 includes an outer cover 220, a fan body 230, an electrical connection portion 240, and a front frame 250. The outer cap 220 includes a cap body 221 and a cap groove 222. The cover groove 222 is recessed in one surface of the cover body 221. The fan body 230 is located in the cover groove 222 and locked to the cover 221. The cover 221 is, for example, a metal cover, however, the utility model is not limited to the material of the cover 221. The front frame 250 covers the air outlet surface of the fan body 230 in a locking manner. The electrical connection portion 240 is located in the cover slot 222, locked on the cover body 221, and placed on the fan body 230.

In addition, each fan device 210 further includes two second fasteners 260 and two third fasteners 270. The second snap member 260 is oppositely located on the cover body 221. One end of each second clip member 260 is fixedly connected to the cover 221, and the other end is detachably clipped in the second clip interface 133. More specifically, each second clamping member 260 is positioned in the cover slot 222, and a portion of the second clamping member 260 passes through the cover body 221 and is clamped in the second clamping interface 133, and one of the second clamping members 260 is located between the cover body 221 and the electrical connection portion 240. The third fastening member 270 is positioned in the cover slot 222 and disposed opposite to the second fastening member 260, and a portion of the third fastening member 270 passes through the cover 221 and is fastened in a fourth fastening interface (not shown).
