Description

A cooling device and server

technical field

The invention relates to the technical field of heat dissipation, in particular to a heat dissipation device and a server.

Background technique

The server refers to the core computer that serves each computer in the network system. It can provide functions such as disk and printing services required by network users, and also allows various clients to share various resources in the network environment with each other. The basic rack of the server is roughly the same as that of a general personal computer. It is composed of a central processing unit (CPU), a memory (Memory) and an input/output (I/O) device, and is internally connected by a bus (Bus). It is connected, through the north bridge chip to connect the central processing unit and memory, and through the south bridge chip to connect input/output devices and so on. According to the structure of the chassis, the server has gone through three evolutionary processes: from the early tower chassis to the rack type emphasizing centralized performance, and then to the blade server of high-density computing.

The blade server is mainly composed of two parts: the blade server motherboard and the blade server rack. The advantages of blade servers are ease of installation, management, and space savings. For example, a blade server rack is 13U high, and each rack can be equipped with 38 blade server motherboards, including 16 blade server motherboard slots, 16 data system slots, and 6 converter/management system slots. The power supply, network connection, and storage services required by each blade server motherboard are provided through the backplane, so a lot of space can be saved. Each blade server motherboard is actually a system motherboard, and each blade server is an independent computer system with its own central processing unit, memory, hard disk and other electronic devices on the motherboard. Shared power supply, cooling system, some cables etc.

Fig. 1 shows the schematic diagram of the internal structure of the existing server, including a server rack 10, in which a fan 11, an I/O blade module 12 and other blade modules 13 are arranged, each module is connected by a bus For connection and communication, the existing servers all adopt air cooling for heat dissipation, that is, use the heat dissipation fan 11 shown in the figure or other radiators for heat dissipation. With the improvement of blade server performance, its calorific value has also been increasing, and most of the current blade servers or rack servers use fans in parallel and in series for fan heat. When the individual components in the server reach the predetermined limit temperature , can only be cooled by increasing the speed of the fan, which will increase the power consumption and noise of the fan, and will also affect the service life of the fan.

Please refer to FIG. 2, which is a schematic diagram of the internal structure of the server in the embodiment of the present invention, including a server rack 20, in which a cooling device, an I/O blade module 22 and other blade modules 23, I/O The blade module 22 communicates with other blade modules 23 through a bus.

The heat dissipation device includes an air supply device 21, a temperature control device, a sensor and guide vanes 24, wherein: the guide vanes 24 and the air supply device 21 are fixed on the server rack 20, and the sensor is located on the air supply port where the air supply device 21 is located, namely The guide vane 24 is arranged on the air supply port of the air supply device 21 on the air supply channel of each corresponding blade module 23 , or on each corresponding blade module 23 for sensing the temperature of the corresponding blade module 23 .

After the air supply device 21 starts to supply air, each sensor senses the temperature of the corresponding blade module 23, and the sensed temperature signal (specifically, it can be the temperature value of the sensed blade module 23 or the temperature difference exceeding the predetermined threshold) sent to the temperature control device. The temperature control device is located on the main board of the corresponding circuit in the server. The temperature control device determines the blade module with a relatively high temperature at this time according to the transmitted temperature signal, and then adjusts the deflection of the guide vane to the blade module with a high temperature signal, so that the air flow Most of the air flow provided by the air supply device 21 is guided to the blade module with a higher temperature.

In the embodiment of the present invention, the temperature control device includes a gear adjustment circuit, and the gear circuit stores the corresponding relationship between each blade module 23 and the deflection angle of the adjustment guide vane 24, that is, according to the position of each blade module 23 The angle at which the guide vanes 24 need to be deflected is set. When it is necessary to guide the wind flow to one of the blade modules, it is only necessary to control the deflection angle of the guide vanes 24 corresponding to the blade modules. After the sensor 24 senses the temperature of the blade module 23 and returns the sensed temperature signal to the gear adjustment circuit, the gear adjustment circuit determines the blade module with a higher temperature according to the temperature returned by the sensor. , and then according to the corresponding relationship between each blade module 23 and adjusting the deflection angle of the guide vane 24, adjust the deflection angle of the guide vane 24 to a preset deflection angle, so as to transfer the airflow provided by the air supply device to the blade with higher temperature on module 23.

The server in the embodiment of the present invention only uses one air supply device 21 to dissipate heat. In actual demand, one or more side-by-side air supply devices 21 can be arranged in the server rack 20. The air outlets are equipped with guide vanes 24 that can automatically adjust the wind direction. The heat dissipation device and the blade module 23 are arranged side by side in the server. to the corresponding blade module 23.

Fig. 3 shows a schematic structural view of a heat dissipation device in an embodiment of the present invention, a plurality of fans 53 and guide vanes 52 are arranged in the heat dissipation device 51, five fans 53 and guide vanes 52 are shown in the figure, the guide vanes The blade 52 is provided at the air supply port of the fan 53 . The heat dissipation device also includes a gear adjustment circuit, a sensor 54 and a positioning gear. The gear adjustment circuit is located in the control device of the server, and the sensor 54 is located near the heat-generating object. The embodiment of the present invention uses a blade module as an example for illustration . When the chip temperature of a certain blade module exceeds a predetermined limit, the sensor 54 pre-set on the blade module will feed back the sensed temperature signal (specifically, the temperature exceeds the predetermined threshold value) to the temperature control device in the server. The temperature control device includes a gear adjustment circuit, the gear adjustment circuit receives the temperature signal, and according to the preset program, automatically adjusts the deflection of the guide vane 52 in a certain direction so that the air flow turns to the blade module whose temperature exceeds the standard. If the temperature of multiple blade modules is too high, you can adjust the corresponding guide vanes on each blade module to deflect in a certain direction so that the airflow turns to multiple blade modules with too high temperature. blade module.

Specifically, the corresponding relationship between each blade module and the adjustment guide vane 52 deflection angle is stored in the gear position circuit, that is, the deflection angle of the guide vane 52 is preset according to the position of each blade module. When reaching one of the blade modules, it is only necessary to control the deflection angle of the guide vane 52 corresponding to the blade module. After the sensor 54 senses the temperature of the blade module and returns the sensed temperature signal to the gear adjustment circuit, the gear adjustment circuit determines the blade module with a higher temperature according to the temperature returned by the sensor. Then, according to the corresponding relationship between each blade module and the deflection angle of the adjustment guide vane 52, adjust the deflection angle of the guide vane 52 to a preset deflection angle, so as to transfer the airflow provided by the air supply device to the blade module with a higher temperature .

The automatic adjustment of the direction of the guide vane 52 can be realized by adjusting the positioning gear or other methods, and the gear adjustment circuit adjusts the positioning gear according to the temperature change to change the direction of the guide vane 52 and transfer the wind flow to the blade module. Through the implementation of the method, the purpose of protecting the device can be achieved without increasing the speed of the fan or sacrificing the performance of the fan, thereby saving energy, reducing noise, and improving the service life of the fan. In actual implementation, the corresponding number of fans can be set according to the space size of the server and the specific number of blade modules. If relatively few blade modules are deployed, fewer fans and corresponding guide vanes can be installed to maximize the heat dissipation and air supply performance. good. If all the blade modules reach the limit position during this process, the deflection angle of the guide vanes 52 can be adjusted to the best position through the gear position adjustment circuit or the air flow guide adjustment can be adjusted to the best, so that the air flow obtained in the blade modules At most, to achieve the best cooling effect.

When the guide vane 24 is applied to a blade server, when there are fewer blade modules, the guide vane 24 can better guide the air flow provided by the air supply device 21 to the blade module with a higher temperature through the air duct. The guide vane 24 can also be applied to other servers. By configuring with the air supply device in other servers, the wind provided by the air supply device can be guided to the corresponding components through the air duct inside the server, thereby reducing the number of components. local heating.

To sum up, through the heat dissipation device in the embodiment of the present invention, the air supply to the server can be more reasonably distributed to required modules, and the air supply efficiency of the system can be improved. By using the guide vanes in the heat dissipation device, the air flow provided by the air supply device can be effectively and rationally used without increasing the fan speed in the air supply device, thereby prolonging the service life of the fan and solving the uneven air supply of the server And the system waste caused by wind.
