In view of the above objects, a first aspect of embodiments of the present invention proposes an embodiment of a method for increasing the heat dissipation efficiency of a CPU. Fig. 1 shows a schematic flow diagram of the method.
As shown in fig. 1, the method may include the steps of:
s1 monitors the temperature and usage of each CPU, compares the temperature of the CPU with a temperature threshold and compares the usage of the CPU with a usage threshold, in a system in which a plurality of CPUs are arranged, the use condition of each CPU is different, resulting in different temperatures and use rates, therefore, different heat dissipation strategies need to be used, firstly, a damper door (a windshield) is arranged at the air vent of each CPU and each fan, the air damper can be opened or closed, when the air damper is opened, the air of the fan can be directly blown onto the CPU to enable the CPU to achieve the maximum cooling effect, when the wind damper is closed, the air of the fan cannot be directly blown onto the CPU, at the moment, the heat dissipation of the CPU needs to flow by the airflow in the case, the air damper can be partially opened according to the actual situation to enable part of the air of the fan to be directly blown onto the CPU, and the opening or closing or opening of the air damper is jointly determined by the current temperature and the utilization rate of the CPU;
s2, responding to the fact that the temperature of a CPU is greater than a temperature threshold value and the utilization rate is greater than a utilization rate threshold value, sending an instruction for opening a damper door to a BMC, and when the temperature of a certain CPU is greater than the temperature threshold value and the utilization rate is also greater than the utilization rate threshold value, indicating that the CPU is continuously and efficiently operated and needs to carry out maximum heat dissipation, wherein at this time, a corresponding instruction needs to be sent to the BMC for controlling the damper door to be opened or closed so as to open the damper door;
s3 is in response to receiving the instruction to open the damper door, the BMC fully opens the damper door provided between the corresponding CPU and the fan so that the cooling air is directly blown to the corresponding CPU, in which case the CPU needs to perform maximum heat dissipation, and the damper door needs to be fully opened so that the cooling air is directly blown to the CPU.
Through the technical scheme of the invention, a better heat dissipation effect can be achieved when the CPU needs different heat dissipation requirements, the power consumption consumed by a system fan can be reduced, the power consumption efficiency of the whole system is improved, and an energy-saving effect is achieved.
In a preferred embodiment of the present invention, the method further comprises:
responding to the condition that the temperature of the CPU is greater than a temperature threshold value and the utilization rate is less than a utilization rate threshold value, and sending a first instruction for opening a damper door to the BMC;
in response to receiving a first instruction to open the damper door, the BMC opens the damper door provided between the corresponding CPU and the fan by 50% to blow a part of the cooling air directly to the corresponding CPU. The temperature of the CPU is higher than the temperature threshold value, which indicates that the CPU needs to dissipate heat, but the utilization rate is lower than the utilization rate threshold value, which indicates that the CPU does not reach a good operation state, so that the CPU does not need to dissipate heat to the maximum, and at this time, an instruction is sent to the BMC to open the damper partially, which is set to 50% open, or set to other values according to actual conditions.
In a preferred embodiment of the present invention, the method further comprises:
responding to the condition that the temperature of the CPU is smaller than the temperature threshold and the utilization rate is larger than the utilization rate threshold, and sending a second instruction for opening the air damper to the BMC;
in response to receiving the second instruction to open the damper door, the BMC opens the damper door provided between the corresponding CPU and the fan by 25% to blow a part of the cooling air directly to the corresponding CPU. The temperature of the CPU is smaller than the temperature threshold value, which indicates that the CPU does not need to effectively dissipate heat at present, but the utilization rate is larger than the utilization rate threshold value, which indicates that the CPU has reached a good operation state, so that the CPU is judged to generate more heat in the next operation, and partial heat dissipation is needed, and at this time, an instruction is sent to the BMC to partially open the windshield, which is set to be 25% open, or set to be other values according to actual conditions.
In a preferred embodiment of the present invention, the method further comprises:
responding to the fact that the temperature of the CPU is smaller than the temperature threshold value and the utilization rate is smaller than the utilization rate threshold value, and sending a third instruction for opening the air damper door to the BMC;
in response to receiving a third instruction to open the damper door, the BMC opens the damper door provided between the corresponding CPU and the fan by 10% to blow a part of the cooling air directly to the corresponding CPU. The temperature of the CPU is smaller than the temperature threshold value, which indicates that the CPU does not need to effectively radiate heat at present, and the utilization rate is smaller than the utilization rate threshold value, which indicates that the CPU does not reach a good running state, so that the CPU is judged not to need to effectively radiate heat, but in order to prevent the CPU from accumulating too fast temperature in the continuous running process, an instruction is sent to the BMC to enable the windshield to be partially opened, wherein the opening is set to be 10% or other values according to actual conditions.
In a preferred embodiment of the present invention, the method further comprises:
in response to all CPUs having a temperature less than the temperature threshold and a utilization less than the utilization threshold,
sending a fourth instruction for opening the air blocking door to the BMC;
in response to receiving the fourth instruction to open the damper door, the BMC opens the damper door provided between the corresponding CPU and the fan by 20% to blow a part of the cooling air directly to the corresponding CPU. When all the CPU temperatures are smaller than the temperature threshold and the utilization rate is smaller than the utilization rate threshold, it is indicated that the current system does not operate well, the CPUs do not need to perform effective heat dissipation, and none of the CPUs need more heat dissipation, but in order to prevent the CPUs from accumulating too fast in the continuous operation process, an instruction is sent to the BMC to open the windshield, wherein the instruction is set to 20% open, or other values can be set according to actual conditions. And the rotating speed of the fan can be properly reduced.
Through the technical scheme of the invention, a better heat dissipation effect can be achieved when the CPU needs different heat dissipation requirements, the power consumption consumed by a system fan can be reduced, the power consumption efficiency of the whole system is improved, and an energy-saving effect is achieved.
