In the server market, due to the advantages of air-cooled heat dissipation, such as high cost performance, high reliability and easy maintenance, the server cooling system usually adopts air-cooled heat dissipation. The fan speed regulation in the air-cooled cooling system is generally based on the temperature of the main heat-generating components.

The fan will be triggered to adjust the speed, and at this time, the heat of the heating device has actually accumulated for a long time, so that the fan needs to use a higher speed or more time to adjust the temperature of the heating device to a reasonable temperature.

Referring to FIG. 3, it is a schematic flowchart of a fan speed adjustment method provided by an embodiment of the present invention. As shown in FIG. 3, an embodiment of the present invention shows the process of the controller implementing the fan speed adjustment method:

Step S101: Acquire characteristic information and operating current of each heat-generating device, where the feature information is used to describe the feature of the heat-generating device.

The characteristic information may include one or more combinations of device type, power consumption of the device, and target temperature. The device type is used to describe the type, specification, etc. of the heat-generating device. In an exemplary embodiment, the device type may include memory, CPU, GPU, etc., so that the heat-generating device can be further distinguished by the device type as memory, CPU, etc. or GPU. The power consumption of the device may be the rated power consumption or peak power consumption of the heat-generating device, etc., which is used to describe the power consumption of the heat-generating device during operation. The target temperature is the highest working temperature of the heating device set according to the heat dissipation design of the server. In the specific temperature control, the heating device needs to be controlled not to be higher than the target temperature, and different heating devices may have the same or different target temperature. In this way, through the above feature information, the controller can match different current tachometers according to the device type in subsequent steps, so as to implement different control strategies for different heating devices.

In addition, during specific implementation, the characteristic information of each heat-generating device may be stored in a register, and the controller obtains the characteristic information of each heat-generating device by accessing the register. The feature information can be stored in the register of the heating device itself, or independently set in the register on the motherboard; moreover, the communication method between the controller and the register is not limited, and can be accessed through the I2C bus.

Step S102: Select a current tachometer matching the feature information.

In order to achieve unified management of current tachometers, a list library of current tachometers can be established, the list library is used to manage one or more current tachometers, and each current tachometer has a corresponding relationship with the above characteristic information. For a current tachometer, it is used to describe the corresponding relationship between current and rotation speed for a heating device for a characteristic information, that is, one current corresponds to one rotation speed.

In the specific implementation, according to the overall heat dissipation design of the server system, each heating device needs to be controlled to different target temperatures, that is, each heating device should not be higher than its own target temperature, in order to achieve the overall cooling effect. In order to achieve precise control of each heating device, Different heating devices use different control strategies. Moreover, by establishing a current tachometer database, it is possible to achieve automatic matching of heating devices of different types and specifications, without the need to manually formulate heat dissipation strategies one by one, thereby improving the reusability and the flexibility of the speed regulation method.

In the first implementation case, referring to FIG. 4 , it is a schematic flowchart of a current tachometer matching method provided by an embodiment of the present invention. As shown in FIG. 4 , the method shows that different types of The process of flexible speed regulation of the device, the method includes:

Step S1021: Select a list set matching the device type from a list library, wherein the list library includes list sets corresponding to different device types.

In this embodiment of the present invention, the list library is implemented by: dividing into multiple list sets according to device types, and each list set is further divided into multiple current tachometers according to different target temperatures. As shown in Table 1, in an exemplary embodiment, the list library includes a GPU list set, a CPU list set and a memory list set; for the GPU list set, there are corresponding current tachometers for different target temperatures, that is, GPU- The 30 current tachometer represents the current tachometer with the GPU's target temperature of 30°C, the GPU-50 current tachometer represents the GPU's target temperature of 50°C, and the GPU-70 current tachometer represents the GPU's target temperature of 70°C The current tachometer has the same definition rules as above for other CPU list sets and memory list sets, and will not be repeated here. This creates a library of lists for different device types and target temperatures.

Table I:

list set 30℃ 50℃ 70℃ GPU GPU-30 Current Tachometer GPU-50 Current Tachometer GPU-70 Current Tachometer CPU CPU-30 Current Tachometer CPU-50 Current Tachometer CPU-70 Current Tachometer Memory Memory-30 ampere tachometer Memory-50 ampere tachometer Memory-70 ampere tachometer

Step S1022: Select a current tachometer matching the target temperature from the list set, wherein the list set includes the current tachometer of the target temperature.

During the matching process, the corresponding current tachometer can be selected according to the device type and target temperature obtained in the above steps. In an exemplary embodiment, when it is obtained that the device type is CPU and the target temperature is 50° C., a CPU list set can be selected, and a CPU-50 current tachometer can be further selected from the CPU list set. In this way, through the above process, matching of current tachometers of all types of heating devices can be achieved.

In the second implementation case, referring to FIG. 5 , it is a schematic flowchart of another current tachometer matching method provided by an embodiment of the present invention. As shown in FIG. 5 , the method shows the power consumption and target of the heating device. The process of realizing flexible speed regulation of heating devices of different specifications by temperature, the method includes:

Step S1023: Select a list set that matches the power consumption of the device from a list library, wherein the list library includes list sets corresponding to different device power consumptions.

Step S1024: Select a current tachometer matching the target temperature from the list set, wherein the list set includes current tachometers with different target temperatures.

According to the description of the above embodiment, the corresponding current tachometer can also be selected by matching the power consumption of the device and the target temperature. In an exemplary embodiment, when it is obtained that the power consumption of the device is 20W and the target temperature is 30°C, a list set corresponding to 20W can be selected, and a current tachometer corresponding to 30°C can be selected from the 20W list set in parallel. In this way, through the above process, the matching of the current tachometers of all the power consumption index heating devices can be achieved.

In the third implementation situation, referring to FIG. 6 , it is a schematic flowchart of another current tachometer matching method provided by an embodiment of the present invention. As shown in FIG. 6 , the method shows the type and power consumption of the heating device. The process of realizing flexible speed regulation of heating devices of different types and specifications, the method includes:

Step S1025: Select a first current tachometer matching the first device type.

Step S1026: Select a second current tachometer matching the second device type, wherein, in the same temperature range, the rotation speed difference of the first current tachometer is greater than the rotation speed difference of the second current tachometer.

The embodiment of the present invention shows that a specific current tachometer is configured for heating devices with different power consumption. In an exemplary embodiment, the first device type is CPU and the second device type is memory, then according to the above-mentioned first device type and second device type, a CPU current tachometer is obtained for the CPU heating device, as shown in Table 2. , obtain the memory current tachometer for the memory heating device, as shown in Table 3. Since the power consumption of the CPU is greater than the power consumption of the memory, in an exemplary embodiment, the rate of change of the rotational speed of the heat-generating device of the CPU type is required to be greater than the rate of change of the rotational speed of the heat-generating device of the memory type. In the current range of 6A-8A, for CPU heating devices, the speed difference is 1000, and for memory heating devices, the speed difference is 500, so that for devices with fast heat accumulation, the speed of current speed adjustment can be increased to speed up heat dissipation, For devices with slow heat accumulation, power consumption can be saved by reducing the current speed regulation speed.

For example, the corresponding current tachometer is obtained by matching only one of the device type, target temperature and power consumption of the heating device, or the current tachometer is selected by combining the matching of the device type, the target temperature and the power consumption of the heating device.

In addition, in the specific implementation, the corresponding current tachometer can be selected according to the heating devices with different characteristic information in the same air duct based on the design of the air duct.

In the first implementation, when the heating elements located in the same air duct are of the same type, the current tachometer with a higher target temperature is selected. The first memory 51 and the second memory 52 are located in the same air duct, the device type of the first memory 51 is memory, the target temperature is 30°C, the device type of the second memory 52 is memory, and the target temperature is 50°C, then the selection type is Internal memory, current tachometer with target temperature of 50°C.

In the second implementation case, when the heating devices located in the same air duct are of different types, a current tachometer with high power consumption is selected. When the first processor 61 and the first memory 51 are located in the same air duct, the device type of the first processor 61 is CPU, the power consumption is 20W, the device type of the first memory 51 is memory, and the power consumption is 10W, then select Type is CPU, current tachometer with power consumption of 20W.

Step S103 : Determine the rotational speed corresponding to the working current according to the selected current tachometer, and set the fan corresponding to the heating device to the rotational speed.

If the device type of the memory 51 is memory and the power consumption is 10W, then the current tachometer with the type of CPU and the power consumption of 20W is selected, and the second fan 72 in the air duct is used to control heat dissipation. Then, according to the operating current of the heating device corresponding to the selected current tachometer, that is, the operating current of the first processor 61, a corresponding rotational speed is selected, and the second fan 72 is configured at the rotational speed.

In an exemplary embodiment, the first memory 51 corresponds to the first fan 71 , and the detected temperature of the first memory 51 is obtained after adjusting the rotational speed of the fan according to the current tachometer corresponding to the first memory 51 . A threshold temperature is preset, and the threshold temperature can be the highest temperature at which the first memory 51 works according to the heat dissipation design, or the target temperature in the above-mentioned embodiment. When the detected temperature is higher than the threshold temperature, it represents the current rotational speed If the heat dissipation requirement cannot be met, the current tachometer corresponding to the memory is further corrected to increase the fan speed corresponding to the current working current of the first memory 51 .
