[ detailed description ] embodiments

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

In the description of the present application, it is to be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings for convenience in describing the present application and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner, and are not to be considered limiting of the scope of the present application. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the utility model of the present application, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art through specific situations.

Referring to fig. 1, the server includes a main board 50, a first temperature sensor 30, a fan 20, a storage unit 40, and a control unit 10. The main board 50, the first temperature sensor 30, the storage unit 40, and the control unit 10 may be disposed in a housing of the server to provide support and protection, and the fan 20 may be disposed on the housing to exchange heat inside the housing with the outside of the server. The main board 50 may be integrated with a BMC chip having a storage unit 40, a control unit 10, a working condition detection unit 80, and the like, which may be used to store temperature information, read and send temperature signals, and detect and control the fan 20, respectively. In order to protect the server product in a safe working environment and prevent problems such as abnormal overheating, the first temperature sensor 30 is used for sensing the temperature of the motherboard 50, the fan 20 is used for heat dissipation of the server, the storage unit 40 is pre-stored with at least two temperature intervals with different temperatures, and the control unit 10 is respectively connected to the fan 20, the first temperature sensor 30 and the storage unit 40. The control unit 10 controls the duty ratio of the fan 20 to increase or decrease according to a temperature interval corresponding to the temperature of the main board 50 sensed by the first temperature sensor 30. For example, if the currently sensed temperature of the motherboard 50 is in a higher temperature interval, the duty ratio of the fan 20 is controlled to be increased, so that the rotating speed of the fan 20 is increased, and the cooling capacity of the fan 20 is enhanced; if the sensed temperature of the motherboard 50 is in a lower temperature range, the duty ratio of the fan 20 is controlled to be reduced, so that the rotating speed of the fan 20 is reduced, the electric power is saved, and the noise is reduced. The specific values of the temperature intervals can be selected and set according to different types of servers, and preferably, the temperature value ranges between different temperature intervals do not have parts which are overlapped with each other.

It should be noted that the number of the temperature intervals may be two, three, four or more, and is not limited herein. The plurality of different temperature intervals may correspond to different duty cycles of the fan 20, and the greater the number of temperature intervals, the greater the flexibility of adjustment of the fan 20.

In one embodiment, the server further comprises a second temperature sensor 60 for sensing the junction temperature of the CPU 70. A second temperature sensor 60 may be provided in the housing of the server and connected to the control unit 10 to feed back to the control unit 10 a temperature signal of the junction temperature of the CPU 70. The memory unit 40 is also pre-stored with an alarm temperature, the control unit 10 determines according to the junction temperature of the CPU70 sensed by the second temperature sensor 60, and when the temperature is higher than the alarm temperature, the control unit 10 generates a first alarm signal, which can be used for an audio-visual device, a display, etc. to output signals to the outside for a human to receive. For example, in one embodiment, the server further comprises a buzzer or an alarm lamp 90, or both, connected to the control unit 10, and the buzzer or the alarm lamp 90 is an acousto-optic device that can receive the first alarm signal and emit acousto-optic information for warning the person. Preferably, the junction temperature of the CPU70 collected by the second temperature sensor 60 may be transmitted to the BMC through an Operating System (OS) and a platform management tool ipmitool.

In one embodiment, the server further includes a condition detection unit 80 for detecting the operating condition of the fan 20. The operation condition detecting unit 80 may be disposed in the housing of the server and connected to the control unit 10, so as to feed back the operation state information of the fan 20, especially the abnormal operation state information, such as the over-low rotation speed or the stall, to the control unit 10. When the fan 20 detected by the operating condition detecting unit 80 has a fault such as too low rotation speed or stalling, the control unit 10 generates a second warning signal, and the warning signal can also be used for outputting a signal to the outside by an acousto-optic device, a display and the like for a person to receive. For example, in one embodiment, the server further comprises a buzzer or an alarm lamp 90, or both, connected to the control unit 10, and the buzzer or the alarm lamp 90 may be an acousto-optic device that receives the second warning signal and emits acousto-optic information for warning the person.

In one embodiment, there are a plurality of fans 20, and when the control unit 10 detects that there is a failure of a fan 20 according to the operating condition detecting unit 80, the duty ratios of the other fans 20 are controlled to 100%, so that the normal fan 20 can increase the operating speed or operate at full speed, thereby preventing local abnormal temperature rise caused by a failure of an individual fan 20, and preventing the entire server from being affected, and ensuring the safety of the server. Of course, when the control unit 10 detects that all the fans 20 are normal according to the operating condition detecting unit 80, the original duty ratio of the fans 20 is restored or maintained to reduce unnecessary power consumption and noise.

It should be noted that the number of the fans 20 may be two, three, four or more, and is not limited herein. The plurality of fans 20 can improve the heat dissipation capability, reduce the possibility of shutdown and even damage of the server caused by the failure of the individual fans 20, and the more the fans 20 are arranged, the stronger the cooling capability is. Preferably, the fans 20 have at least four.

In one embodiment, the storage unit 40 is further pre-stored with a power-off temperature, the control unit 10 determines the power-off temperature according to the junction temperature of the CPU70 sensed by the second temperature sensor, and the control unit 10 powers off the server when the power-off temperature is higher than the power-off temperature. Specifically, the control unit 10 may be connected to a power supply of the server, cut off the power supply by sending a corresponding power-off signal, perform fuse protection by powering off the entire server, and avoid an irreparable accident to the server caused by the overtemperature of the CPU 70.

In light of the foregoing description of the preferred embodiments according to the present application, it is to be understood that various changes and modifications may be made without departing from the spirit and scope of the utility model. The technical scope of the present application is not limited to the contents of the specification, and must be determined according to the scope of the claims.
