Description

Technical Field

[0001] The utility model belongs to the technical field of server temperature control, and in particular relates to an intelligent temperature control and speed regulation device for key components of a server and a server. Background Art

[0002] During the operation of the server, each electronic component inside the server consumes power and dissipates heat. For example, as the core processing unit, the power consumption and heat generation of the CPU often determine the cooling requirements of the entire server. Traditional cooling methods usually rely on fixed fan speeds or simple temperature response mechanisms, which are inadequate when dealing with complex and changing load conditions. On the one hand, if the fan speed is set too high, although it can effectively dissipate heat, it will increase unnecessary energy consumption and noise; on the other hand, if the fan speed is set too low, it may not be able to remove heat in time, causing the server to overheat.

[0003] As the integration of server hardware continues to increase, the power consumption and heat generation of key components such as CPUs and hard disks are also increasing, which puts higher requirements on the server's cooling system. Therefore, a more intelligent and efficient cooling control solution is needed that can dynamically adjust the fan speed according to the actual load and temperature conditions of the server to achieve the best balance between cooling effect and energy consumption.

[0004] As server processing power improves and power consumption increases, ensuring that the server can maintain a stable operating temperature under high load and preventing hardware damage or performance degradation due to overheating has become a technical problem that needs to be solved urgently.

Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0039] Specifically, this embodiment mainly acquires the power consumption of key components in the server, monitors the power consumption of key components in real time, and adjusts the speed of the fan module based on the temperature information and power consumption information of the key components. In this way, by recording the power consumption and temperature information of the key components of the server, the corresponding fan module speed is matched, and the fan module speed can be automatically adjusted, effectively cooling the key components of the server and ensuring the stable operation of the server.

[0040] Key server components may include but are not limited to CPU, memory, hard disk, motherboard, network card, disk and fan.

[0041] This embodiment takes CPU temperature control as an example, and the BMC module obtains CPU temperature information by communicating with the PCH south bridge module.

[0042] Optionally, a thermal diode is installed on the CPU, and the BMC module obtains the temperature information of the CPU by connecting to the thermal diode. The BMC module can determine the current operating temperature information of the CPU based on the temperature detected by the PCH south bridge module (Platform Controller Hub, PCH) or the thermal diode, and adjust the fan module speed to cool the CPU.

[0043] The power consumption detection component of this embodiment can detect the power consumption of the entire server, the CPU power consumption and the hard disk power consumption.

[0044] Specifically, the power consumption detection components include: current acquisition module, voltage detection module, amplifier circuit, AD conversion circuit, single chip microcomputer and serial port to network card module.

[0045] The single chip microcomputer obtains the current information and voltage information of the overall operation of the server through the current acquisition module and the voltage detection module in turn, and obtains the power consumption of the whole server based on the current information and voltage information.

[0046] The current acquisition module and voltage detection module can detect the current information and voltage information of the server power input side respectively, and then the overall power consumption of the server can be obtained. The single-chip microcomputer communicates with the BMC module through the serial port to network card module and sends the power consumption of the server to the BMC module.

[0047] It should be noted that the memory power consumption of the server can be obtained. For example, taking a memory stick with a power consumption of 8 W as an example, the power consumption of 5 memory sticks can reach 40 W.

[0048] The BMC module reads the current information of the current monitoring chip CPU through the SPI interface, and then obtains the voltage value. Based on the read current and voltage values, the BMC module can calculate the power consumption of the CPU.

[0052] For this embodiment, the preset CPU temperature threshold is 75° C. to 85° C., and can be set to 75° C. according to actual work needs.

[0053] The BMC module can collect CPU temperature by communicating with the timing module to obtain the monitoring time period of the CPU temperature. For example, the BMC module monitors the change of CPU temperature, sets the CPU temperature threshold, and can pre-match different speeds of the fan module according to different CPU operating temperature ranges. The CPU temperature can be collected every t seconds and matched with the corresponding fan module speed.

[0054] The CPLD module uses I 2 The C interface is connected to the BMC module to process the fan speed control instructions. Optionally, a PID control module can also be configured. The BMC module is also connected to the fan module through the CPLD module and the PID control module to control the speed of the fan module. The PID control module implements closed-loop control of the fan module speed.

[0056] This embodiment also controls the fan module rotation speed in combination with the CPU power consumption information.

[0057] When the CPU is running, as the amount of data processed increases, the power consumption information also increases, and of course the operating temperature will also increase. When the BMC module determines that the CPU power consumption information is greater than the preset power consumption threshold and the CPU temperature information is lower than the preset temperature threshold, the fan module speed is controlled to increase to the second speed.

[0058] In this embodiment, the first speed and the second speed may be the same speed information, or different speeds may be set as needed.

[0059] As for the fan module speed of this embodiment, the fan module includes multiple fans; the output power of each fan is 3~20W, and the output air volume is 100~240 CFM / kW; the BMC module controls the air supply volume and speed of the fan according to the CPU temperature information and CPU power consumption.

[0060] For example, the BMC module sets the fan module speed based on the CPU temperature information. The real-time power consumption of the CPU is P, and the rated power consumption of the CPU is P. 额 The BMC module controls the air flow F of the fan module, which can be configured as F=AP 额 .

[0061] Where A is the air supply volume, which can be set to 90~180 CFM / kW.

[0062] The speed Z can be configured as Z=P / P 额 .

[0063] In this embodiment, the device further includes: a power monitor, a detection resistor, a CRPS power module, and a 12V to 3.3V voltage conversion circuit; the detection resistor is arranged on the power supply line between the CRPS power module and the server power module, and the BMC module is connected to the detection resistor through the power monitor to obtain power supply voltage information; the power monitor is connected to the BMC module and the CPLD module through the 12V to 3.3V voltage conversion circuit to supply power to the BMC module and the CPLD module respectively. In this way, the power supply requirements of the BMC module and the CPLD module can be met.

The CPU can be stress-tested by calling different stress-testing tools. The CPU power consumption can be increased and the corresponding temperature changes can be achieved, and the fan speed can be adjusted.

[0066] Optionally, the BMC module can obtain the power consumption of key components in the server based on the raw command and store it. The fan speed of the server can be obtained. The power consumption of the components is monitored in real time, and the raw command is called cyclically to monitor the power consumption value of the key components in real time to determine whether the power consumption value reaches the stored power consumption value of the key components. Combined with the control of fan speed regulation, the temperature of the monitored key components can be adjusted. The intelligent pre-judgment speed regulation function of the key components can be automatically realized.
