All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The terms "first", "second" and "first" 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" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
In the operation process of the electronic equipment, a power device of the electronic equipment generates a large amount of heat, and the heat of the power device needs to be dissipated through the rotation of a heat dissipation fan. Some embodiments set a fixed rotational speed for the cooling fan at which the cooling fan operates.
However, the heat dissipation requirements of power devices of different electronic devices are different, and if the heat dissipation requirement of the power device is large, the heat dissipation fan is difficult to meet the heat dissipation requirement of the power device; if the heat dissipation requirement of the power device is small, the heat dissipation fan generates unnecessary power consumption.
In view of this, the embodiment of the utility model provides a fan adjustment device and an electronic apparatus for reasonably adjusting the rotation speed of a fan. The fan adjusting device includes: the parameter determining unit is used for determining the measurement parameters of the electronic equipment, and the measurement parameters comprise current load information and/or current environment temperature; and the rotating speed processing unit is used for determining the target rotating speed of the fan corresponding to the power device in the electronic equipment based on the measured parameters and controlling the fan to operate at the target rotating speed.
Referring to fig. 1, an application scenario provided in this embodiment includes: the electronic device 100, one or more temperature sensors disposed around the electronic device (fig. 1 illustrates one temperature sensor 200, and in practical applications, more temperature sensors may be disposed around the electronic device), and a fan disposed at the power device 101 in the electronic device 100 (fig. 1 illustrates an example where the electronic device includes one power device, and in practical applications, the electronic device may include more power devices, and each power device corresponds to one fan).
The fan adjusting device 102 in the electronic device 100 may receive the temperature collected by the temperature sensor 200, determine a measurement parameter of the electronic device, determine a target rotation speed of the fan based on the measurement parameter, and control the fan to operate at the target rotation speed.
The above application scenarios are only exemplary, and the embodiments of the present invention are not limited thereto, for example: in practice, more temperature sensors may be provided around the electronic device.
The technical solutions and embodiments of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 2, a fan adjusting device 102 according to an embodiment of the present invention includes:
a parameter determining unit 1021, configured to determine a measurement parameter of the electronic device, where the measurement parameter includes current load information and/or a current ambient temperature;
a rotation speed processing unit 1022, configured to determine a target rotation speed of a fan corresponding to a power device in the electronic device based on the measured parameter, and control the fan to operate at the target rotation speed.
The current load information of the electronic device represents how much heat is generated by the power device in the electronic device, the current ambient temperature of the electronic device represents the cold and hot of the ambient environment of the electronic device, and these two parameters reflect the heat dissipation requirements of the power device of the electronic device, for example: the larger the current load information of the electronic equipment is, the more the heat generated by the power device is, and the larger the heat dissipation requirement of the power device is; the higher the current ambient temperature, the hotter the environment surrounding the electronic device, and the greater the heat dissipation requirements of the power device. On this basis, the fan control device needs to determine the current load information and/or the current ambient temperature by means of the parameter determination unit.
The embodiment of the present application does not limit the specific implementation manner of determining the current load information and/or the current ambient temperature by the parameter determining unit.
As described above, a temperature sensor is disposed around the electronic device, and the temperature sensor can acquire the ambient temperature around the electronic device, and in some alternative embodiments, the parameter determination unit may determine the current ambient temperature according to the received temperature acquired by the temperature sensor. The following are exemplary: if only one temperature sensor is arranged around the electronic equipment, the temperature collected by the temperature sensor can be directly used as the current ambient temperature. If a plurality of temperature sensors are arranged around the electronic equipment, the average value of the temperatures collected by the plurality of temperature sensors can be determined as the current environment temperature; or determining the maximum value of the temperatures acquired by the plurality of temperature sensors as the current ambient temperature; alternatively, the minimum value of the temperatures collected by the plurality of temperature sensors is determined as the current ambient temperature or the like.
In some alternative embodiments, the parameter determining unit may determine the current load information according to the actual output current and the rated output current of the electronic device. For example, the ratio of the actual output current to the rated output current is determined as the current load information. Because the actual output current is less than or equal to the rated output current, the value range of the current load information is 0-100%.
As mentioned above, the measured parameters include current load information and/or current ambient temperature. For the measurement parameters including the current load information and the current ambient temperature, the rotation speed processing unit is specifically configured to:
determining the current load information and the rotating speed corresponding to the current environment temperature as the target rotating speed based on a first preset corresponding relation; the first preset corresponding relation comprises corresponding relations among load information, ambient temperature and rotating speed.
Taking the load information value range of 0-100% and the ambient temperature value range of 10-50 ℃ in the first predetermined corresponding relationship as an example, the first predetermined corresponding relationship can be referred to as table 1.
TABLE 1
Figure BDA0003174890720000061
Figure BDA0003174890720000071
Table 1 is an exemplary illustration of the first predetermined corresponding relationship, which should not be construed as a limitation of the present invention.
The corresponding relation among the load information, the ambient temperature and the rotating speed is set in advance, so that the target rotating speed corresponding to the current load information and the current ambient temperature is conveniently determined. For example, the current load information is 10%, the current ambient temperature is 10 ℃, and the target rotation speed is determined to be B1 based on the first preset correspondence; the current load information is 100%, the current ambient temperature is 50 ℃, and the target rotation speed is determined to be K5 based on the first preset correspondence, which is not illustrated herein.
Because the higher the ambient temperature is, the larger the load information is, the larger the heat dissipation requirement of the power device of the electronic device is, the higher the ambient temperature is and the larger the corresponding rotation speed is in the corresponding relationship under the same load information, and the larger the load information is and the larger the corresponding rotation speed is under the same ambient temperature.
Also, taking table 1 above as an example, a1 < a2 < A3 < a4 < a5 at a load information of 0%; when the load information is 10%, B1 < B2 < B3 < B4 < B5; … …, respectively; when the load information is 100%, K1 < K2 < K3 < K4 < K5;
when the temperature is 10 ℃, A1 is more than B1 and more than C1 and more than D1 and more than E1 and more than F1 and more than G1 and more than H1 and more than I1 and more than J1 and more than K1; when the temperature is 20 ℃, A2 < B2 < C2 < D2 < E2 < F2 < G2 < H2 < I2 < J2 < K2; … …, respectively; at the temperature of 50 ℃, A5 < B5 < C5 < D5 < E5 < F5 < G5 < H5 < I5 < J5 < K5.
Therefore, when the current environment temperature is high and the current load information is large, the fan realizes better heat dissipation corresponding to a large target rotating speed.
As mentioned above, the measured parameters include current load information and/or current ambient temperature. For the measurement parameters including the current load information, the rotation speed processing unit is specifically configured to:
determining the rotating speed corresponding to the current load information as the target rotating speed based on a second preset corresponding relation; the second preset corresponding relation comprises a corresponding relation between load information and rotating speed.
Taking the value range of the load information in the second predetermined corresponding relationship as 0-100%, the second predetermined corresponding relationship can be referred to as table 2.
TABLE 2

10% B
20% C
30% D
40% E
50% F
60% G
70% H
80% I
90% J
100% K
Table 2 is an exemplary illustration of the second predetermined corresponding relationship, which should not be construed as a limitation of the present invention.
The corresponding relation between the load information and the rotating speed is set in advance, so that the target rotating speed corresponding to the current load information is conveniently determined. For example, the current load information is 10%, and the target rotation speed is determined to be B based on the second preset correspondence; the current load information is 100%, and the target rotation speed is determined to be K based on the second preset corresponding relationship, which is not illustrated herein.
Since the larger the load information is, the larger the heat dissipation requirement of the power device of the electronic device is, the larger the load information is in the correspondence relationship, the larger the corresponding rotation speed is. Also for the example in Table 2 above, A < B < C < D < E < F < G < H < I < J < K.
Therefore, when the current load information is larger, the fan can better radiate heat corresponding to a larger target rotating speed.
As mentioned above, the measured parameters include current load information and/or current ambient temperature. For the measurement parameters including the current ambient temperature, the rotation speed processing unit is specifically configured to:
determining the rotating speed corresponding to the current environment temperature as the target rotating speed based on a third preset corresponding relation; and the third preset corresponding relation comprises a corresponding relation between the ambient temperature and the rotating speed.
Taking the range of the ambient temperature in the third predetermined corresponding relationship as 10 to 50 ℃, the third predetermined corresponding relationship can be referred to as table 3.
TABLE 3
Ambient temperature Rotational speed
10℃ R
20℃ S
30℃ T
40℃ U
50℃ V
Table 3 is an exemplary illustration of the third predetermined corresponding relationship, which should not be construed as a limitation of the present invention.
The target rotating speed corresponding to the current environment temperature is conveniently determined by setting the corresponding relation between the environment temperature and the rotating speed in advance. For example, the current ambient temperature is 10 ℃, and the target rotation speed is determined to be R based on the third preset corresponding relation; the current ambient temperature is 50 ℃, and the target rotation speed is determined to be V based on the third preset corresponding relation, which is not illustrated one by one here.
Since the higher the ambient temperature is, the greater the heat dissipation requirement of the power device of the electronic device is, the higher the ambient temperature is in the correspondence relationship, the greater the corresponding rotation speed is. Also for the above Table 3, R < S < T < U < V.
Thus, when the ambient temperature is high, the fan can achieve better heat dissipation corresponding to a larger target rotating speed.
As mentioned above, in practical applications, the electronic device may include more power devices, each power device corresponds to one fan, and all fans need to be controlled to operate at the above target rotation speed.
The embodiment of the utility model also provides electronic equipment which comprises any one of the fan adjusting devices provided in the technical scheme.
Specifically, the electronic device may be a power electronic product or the like.
While preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. Therefore, it is intended that the appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the utility model.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
