Description

A plug-in server

technical field

The utility model belongs to the technical field of servers, in particular to a plug-in card server.

Background technique

A server, also called a server, is a device that provides computing services. According to the shape, the server can be divided into plug-in type, box type, tower type, etc. Among them, the more common ones are plug-in type and box type. The composition of the server includes processor, hard disk, memory, system assembly and chipset, etc., which is similar to the general computer architecture, but due to the need to provide high Higher requirements on scalability and manageability.

The server structure commonly used in the industry is usually a box type, with a high-speed axial fan in the middle, front and rear air ducts, and a high-power chip located in the middle of the chassis. The high-speed axial fan and the structurally designed windshield are used to dissipate heat from the high-power chips. However, the function of a single box server is relatively single. For some applications, the server and other business function boards need to be used together in a chassis, which cannot be installed. This has led to the gradual emergence of plug-in card servers and put them into practical applications.

As shown in FIG. 1 , the board body 2 of the plug-in server in the prior art is provided with an embedded chip 1 . There is no fan installed on the plug-in server, and the heat dissipation system of the chassis needs to be used for heat dissipation. However, there is still no good solution in the industry for the fan used to dissipate heat in the case where the plug-in server is installed. The heat dissipation problem of the plug-in card server that consumes a single-board chip (about 10W), its disadvantage is that it cannot solve the heat dissipation problem of the plug-in card server whose embedded chip is a high-power consumption chip (about 84W). Existing plug-in card servers with embedded chips of high power consumption (about 84W) will inevitably use high-speed fans to dissipate heat from the chips. Usually, a chassis equipped with high-speed fans is used to install the plug-in card servers. Since the chassis adopts high-speed fans, the effect is better when all the cards in the chassis are plug-in card servers; when there are other low-power consumption single boards installed in the chassis When installed in the chassis, the chassis continues to use high-speed fans, which will result in waste of heat dissipation for low-power consumption boards, increase design costs, and increase noise and energy consumption, which is not in line with environmental protection requirements. Design requirements.

The air outlet direction of the air guide cover faces the front panel of the board body. The front panel of the board body is provided with an air outlet, and the air outlet of the fan is guided by the air guide cover to form an air duct and the air duct formed by the system fan on the chassis in a cross distribution.

Further, both ends of the air guide cover are openings, and the side of the end of the air guide cover opposite to the air outlet direction is connected through the air outlet of the fan.

Preferably, ventilation holes are opened on both side walls of the air guide cover to facilitate the circulation of wind in the chassis.

Preferably, a first vacant area with a width of 10-40 mm is provided away from the two side walls of the air guide cover, so as to avoid affecting the heat dissipation of surrounding power consumption devices.

Preferably, a second vacant area is set above the air guide cover to facilitate the circulation of wind in the chassis and provide better overall heat dissipation.

The board body 2 is used to carry the embedded chip 1 and other related accessories of the plug-in server, the board body 2 is snap-connected with the chassis, and the front panel of the board body 2 is provided with an air outlet 5 . On the board body 2, the middle part where the embedded chip 1 is installed is provided with an air guide cover 4 covering the embedded chip. The air guide cover 4 is an inverted U-shaped structure, and the two ends and the bottom of the air guide cover 4 are openings. The air outlet direction of the air guide cover 4 is toward the front panel of the board body 2 , and is docked with the air outlet 5 on the front panel. The side wall of the other end of the air guide cover 4 is provided with an interface connected to the turbofan 3, and the interface communicates with the air outlet of the turbo fan 3, so that the outlet wind of the turbo fan 3 is sent into the air guide through the interface connected with the air guide cover 4. The cover 4 dissipates heat from the embedded chip 1 therein.

It should be noted that the main function of the air guide cover 4 is to guide the air out of the turbofan 3 so that the outflow air passes through the embedded chip 1 to dissipate heat for the embedded chip 1 . When the air guide cover 4 is an inverted U-shaped structure, the air duct can be formed best, and it can also be tubular; if the top surface of the air guide cover 4 is removed, only two sides are used, and the chassis or other boards are used to block It is also feasible to form an air duct.

Ventilation holes 6 are provided on the two side walls of the air guide cover 4, and the ventilation holes 6 can provide air circulation for the entire card server, reduce the impact on the air duct of the entire chassis system, and provide air for other functions installed on the board body 2. The device provides good heat dissipation. In this embodiment, the ventilation holes 6 are arranged in a rectangular array, and other embodiments, such as a circular array, are also possible. The shape of the ventilation hole 6 can be any one of round hole, square hole or triangular hole and the like.

At the same time, in order to avoid the problem that the air guide cover 4 blocks the power consumption devices in this interval and cause it to be unable to dissipate heat, a vacant area with a width of 10-40 mm is provided on both sides of the air guide cover 4 on the board body 2. No power consumption devices are arranged in this vacant area, so as to avoid poor heat dissipation of the arranged power consumption devices. A vacant area with a height of 5-10 mm is also arranged above the air guide 4, that is, the height of the air guide 4 is lower than the height of the card server itself, so that as much air volume as possible passes through the top of the air guide 4, To reduce the impact on the air duct of the entire chassis system.

The turbofan 3 in this embodiment is one of the high-speed fans, and other high-speed fans can also be selected, such as common blade-type high-speed fans.

The plug-in card server 10 of the utility model can be mixedly plugged or oppositely plugged in with other business plug-in cards 8 , and the middle is separated by a central backboard, and a cover plate 7 is arranged on the top. In Fig. 3, there are two plug-in card servers 10 pair inserted in the chassis, and the embedded chip 1 of the plug-in card server 10 is a high-power consumption chip, which is dissipated by the turbo fan 3 on the plug-in card server 10. The air from the fan 3 directly enters the wind guide 4, passes through the embedded chip 1, and then comes out from the air outlet 5, forming a horizontal air duct. The chassis itself is provided with a low-speed fan 9, and the wind enters from the other end of the chassis, passes through the vacant area above the air guide cover 4 and the vent 6, and is discharged from the low-speed fan 9 of the chassis, forming a longitudinal air duct. The horizontal air duct and the vertical air duct are perpendicular to each other for more thorough heat dissipation. FIG. 4 shows a schematic diagram of the horizontal air duct and the longitudinal air duct, and the direction of the arrows in the figure indicates the air flow direction of the turbofan 3 and the air flow direction of the chassis system fan.

In this embodiment, the two ends of the air guide cover 4 are openings, and the air outlet of the turbofan 3 comes out from one end, and the end of the air outlet is an air outlet, corresponding to the air outlet 5 of the front panel, and the opposite end is connected with the chassis backplane, so that The wind concentrates towards the wind outlet. The opposite end of the air outlet can also be directly closed, so that the air outlet is concentrated towards one direction.

It should be noted that the chassis of this embodiment is a double plug-in type, the backplane of the chassis is placed in the middle, and cards can be inserted in the front and rear of the chassis, so the air outlet of the air guide cover 4 faces the front panel of the plug-in card server, which is convenient for exporting. wind. But if only one side of the chassis can be inserted into the card, that is, the depth of the chassis can only be inserted into a card-type server, and the card can only be inserted into the chassis from one direction, then the air outlet of the air guide cover 4 can also be set to face the card-type server. At the rear of the server, at this moment, the front panel of the board body 2 does not need to be provided with an air outlet 5, but an air outlet is provided on the rear panel of the cabinet, that is, the air is discharged from the rear of the cabinet.
