The above and other aspects, features and advantages of the present disclosure will become more apparent in view of the following detailed description when taken in conjunction with the accompanying drawings.
Specific embodiments of the present disclosure are described hereinafter with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure that may be embodied in various forms. Well-known and/or repeated functions and structures have not been described in detail so as not to obscure the present disclosure with unnecessary or unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure.
The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the disclosure.
A first aspect of the embodiments of the present disclosure provides a control method for a heat dissipation component, where the heat dissipation component may be used in an electronic device, and the electronic device may be any electronic device having a computing processing function, such as an electronic device of a portable computer, a desktop computer, a server, or other electronic devices having a computing processing function and requiring heat dissipation and dust removal for components such as a processor. The heat dissipation component can be a fan or other device which can realize multiple functions of heat dissipation, cooling, dust removal and the like through the rotation of the blades.
The control method for a heat dissipation component provided by an embodiment of the present disclosure is used for switching the heat dissipation component in the electronic device between a forward rotation mode and a reverse rotation mode, for example, so that the heat dissipation component can implement a heat dissipation operation on a component such as a processor when the forward rotation mode is executed and can also implement a dust removal operation on the component such as the processor when the reverse rotation mode is executed, as shown in fig. 1, specifically including:
and S101, acquiring system information in the forward rotation mode execution process of the heat dissipation component.
In this step, system information is acquired, for example, during a forward rotation mode executed by the heat dissipation member in the electronic apparatus; the heat dissipation component performs a heat dissipation operation on a component, such as a processor, in the electronic device in the forward rotation mode, and acquires system information in the process, where the system information includes at least one of system load information and ambient temperature information, where the system load information is, for example, an operating condition of the processor or a memory, and the ambient temperature information is temperature information of an environment in which the electronic device is located, and the ambient temperature information can be acquired by providing a temperature sensor.
Further, after the heat dissipation component performs the forward rotation mode and acquires the system information, the state information of the heat dissipation component may be collected and acquired, so that when determining the switching of the rotation mode of the heat dissipation component, the state information may be determined based on the operation state of the heat dissipation component, in addition to considering the influences of the system load and the ambient temperature, and for this reason, after the heat dissipation component performs the forward rotation mode and acquires the system information, as shown in fig. 2, the method further includes:
and S201, acquiring the forward rotation speed of the heat dissipation component in the forward rotation mode.
In this step, the rotation speed is a main operation parameter of the heat dissipation component, and the rotation speed determines the output power of the heat dissipation component, and when the heat dissipation component executes the forward rotation mode, the rotation speed determines the heat dissipation power, and when rapid heat dissipation or cooling is needed, the rotation speed of the heat dissipation component is increased, so that rapid heat dissipation can be achieved for components of the electronic device, such as a processor. Therefore, for example, when the temperature of the environment of the electronic device is high, that is, when the cooling requirement of the electronic device is high, the heat dissipation member needs to maintain a high forward rotation speed in the forward rotation mode to achieve rapid heat dissipation, and only when the temperature of the environment is not high, that is, the cooling requirement is low, the heat dissipation member is considered to be switched from the forward rotation mode to the reverse rotation mode, that is, the heat dissipation member needs to consider more dust removal requirements, so that the heat dissipation member can be reasonably used to achieve different functions under different situations, and therefore, the forward rotation speed of the heat dissipation member in the forward rotation mode needs to be obtained.
And S202, judging whether the forward rotation speed exceeds an idle speed threshold value.
After the forward rotation speed of the heat dissipation component is obtained in step S201, it is further determined whether the forward rotation speed exceeds an idle rotation speed threshold, where the idle rotation speed threshold is a rotation speed at which the heat dissipation component keeps rotating basically when the heat dissipation component is started normally and there is no demand for rapid cooling inside the electronic device. By judging whether the forward rotation speed exceeds an idle rotation speed threshold value, whether components in the electronic equipment have higher cooling requirements or whether the normal operation of the components in the electronic equipment is influenced by switching the rotation mode of the heat dissipation component can be determined.
And S203, switching the heat dissipation component from the forward rotation mode to the reverse rotation mode based on the system information when the forward rotation speed does not exceed the preset idle rotation speed.
If it is determined in step S203 that the forward rotation speed does not exceed the preset idle rotation speed, that is, if the components in the electronic device do not have a high cooling demand, the heat dissipation member is switched from the forward rotation mode to the reverse rotation mode based on the system information, that is, the heat dissipation member preferentially satisfies the dust removal demand of the components in the electronic device, and the heat dissipation member is switched to the reverse rotation mode, so that the components in the electronic device are subjected to dust removal operation.
Further, when the normal rotation speed in step S203 does not exceed the preset idle threshold, as shown in fig. 3, the method further includes:
s301, determining whether the duration of the normal rotation mode executed by the heat dissipating component exceeds the first duration.
The method further includes determining a duration of the normal rotation mode executed by the heat radiating member, specifically, determining whether the duration of the normal rotation mode executed by the heat radiating member exceeds the first duration, where the first duration may be, for example, 1 hour, on the basis that the normal rotation speed of the normal rotation mode executed by the heat radiating member meets a condition, that is, the normal rotation speed does not exceed the preset idle threshold.
And S302, when the duration time exceeds the first duration time, switching the heat dissipation component from a forward rotation mode to a reverse rotation mode based on the system information.
In this step, when the duration exceeds the first duration, for example, exceeds 1 hour, the heat radiating member is switched from a normal rotation mode to a reverse rotation mode based on the system information. Therefore, the heat dissipation component can be switched to the reverse rotation mode only when the forward rotation mode needs to be executed and a certain time is reached, so that the heat dissipation or cooling effect of the heat dissipation component is ensured, the temperature of the electronic equipment inner part is not too high, and unnecessary dust removal is not frequently performed.
And S102, switching the heat dissipation component from a forward rotation mode to a reverse rotation mode based on the system information.
In step S101, after system information is acquired during the process of executing the forward rotation mode by the heat dissipation component, the rotation mode of the heat dissipation component is switched based on the system information, specifically, the heat dissipation component is switched from the forward rotation mode to the reverse rotation mode, that is, during the process of executing the forward rotation mode by the heat dissipation component, the rotation mode of the heat dissipation component can be dynamically adjusted according to changes of system load information and/or environmental temperature information based on the system information, and the forward rotation mode for realizing heat dissipation is switched to the reverse rotation mode for realizing dust removal, so that the heat dissipation component is reasonably controlled to be switched from the heat dissipation operation to the dust removal operation under a certain condition.
Specifically, the switching of the heat dissipation member from the normal rotation mode to the reverse rotation mode based on the system information, as shown in fig. 4, includes:
s401, determining a first output duty ratio of the heat dissipation component based on the system information.
On the basis of obtaining the system information, in this step, a first output duty ratio of the heat dissipation component is first determined, where the output duty ratio refers to a ratio of time in which an electrical signal is output in a periodic electrical signal to a whole signal period, the first output duty ratio is determined based on the system information, for example, system load information and/or ambient temperature information may be used as variables, and a mapping relationship is established between the first output duty ratio and the first output duty ratio, the first output duty ratio can represent a ratio of outputting a rotation control signal in a process in which the heat dissipation component executes the forward rotation mode, and a lower value of the first output duty ratio represents a lower ratio of the rotation control signal, that is, the lower requirement of the heat dissipation component for heat dissipation is represented.
S402, when the first output duty ratio is smaller than a first threshold value, the heat dissipation component is switched from a forward rotation mode to a reverse rotation mode.
On the basis that the first output duty ratio of the heat dissipation component is determined through the step S401, the first output duty ratio is compared with a first threshold, and when the first output duty ratio is smaller than the first threshold, that is, the ratio of the rotation control signal is low, that is, the requirement for heat dissipation of the heat dissipation component is low, at this time, switching of the heat dissipation component from a forward rotation mode to a reverse rotation mode may be performed, so as to switch from meeting the requirement for cooling of the electronic device internal component to meeting the requirement for dust removal of the electronic device internal component.
In order to ensure that the heat radiating member does not change greatly in noise level due to the switching of the rotation mode and does not cause discomfort to the user when the heat radiating member is switched from the normal rotation mode to the reverse rotation mode because a certain noise is generated during the rotation of the heat radiating member, the heat radiating member further includes, before the switching of the heat radiating member from the normal rotation mode to the reverse rotation mode based on the system information: the reverse rotation speed in the reverse rotation mode is determined based on the noise level of the heat dissipation component in the process of executing the forward rotation mode, so that the heat dissipation component executes the reverse rotation mode according to the determined reverse rotation speed, namely, after the heat dissipation component is switched to the reverse rotation mode, the noise level of the reverse rotation speed is not changed greatly.
Wherein the determining of the reverse rotation speed in the reverse rotation mode based on the noise level during the execution of the normal rotation mode by the heat dissipation member, as shown in fig. 5, includes:
and S501, acquiring the forward rotation speed of the heat dissipation component in the forward rotation mode.
In this step, the forward rotation speed of the heat dissipating member in the forward rotation mode is first obtained, and the forward rotation speed may be realized by providing a hall sensor in the heat dissipating member, or may be realized by another sensor for detecting the rotation speed.
S502, acquiring a first noise level based on the forward rotation speed.
The first noise level is obtained based on the forward rotation speed after the forward rotation speed of the heat dissipation component in the forward rotation mode is obtained in step S501, specifically, the corresponding relationship between the forward rotation speed and the first noise level may be realized by a pre-obtained lookup table, and the corresponding relationship may be preset in the lookup table through testing, and may of course be realized through detection. As can be seen, for example, in table 1 below:
TABLE 1 noise level of a fan corresponding to different rotation speeds in different rotation modes
S503, determining a reverse rotation speed based on the first noise level, wherein the difference value between a second noise level corresponding to the reverse rotation speed and the first noise level does not exceed a noise threshold value.
In the case of acquiring a first noise level through the above step S502, determining a reverse rotation speed based on the first noise level, wherein a difference between a second noise level corresponding to the reverse rotation speed and the first noise level does not exceed a noise threshold; specifically, when it is determined that the heat dissipation component is switched to the reverse rotation mode, the corresponding relationship between different reverse rotation speeds and noise levels needs to be obtained first, which can be implemented by using the previously obtained lookup table, and further, when it is determined that the reverse rotation speed needs to be maintained within a certain range of the respective noise levels corresponding to the forward rotation speed and the reverse rotation speed before and after switching, so that a large change in the noise level is not generated after switching, and the comfort level of the user using the electronic device is ensured.
S103, after the heat dissipating component enters the inversion mode, acquiring the system information while the heat dissipating component executes the inversion mode.
In the step S102, the heat dissipating unit is switched from the forward rotation mode to the reverse rotation mode based on the system information, and in this step, the system information is acquired again after the heat dissipating unit is switched from the forward rotation mode to the reverse rotation mode, that is, during the reverse rotation mode; the heat dissipation component performs a dust removal operation on a component, such as a processor, in the electronic device in the reverse mode, and acquires the system information in the process, where the system information includes at least one of system load information and environmental temperature information, where the system load information is, for example, an operation condition of the processor or a memory, etc. in the electronic device, and the environmental temperature information is temperature information of an environment in which the electronic device is located, and may be acquired by providing a temperature sensor.
After the system information is acquired in the process of executing the inversion mode by the heat dissipation component, as shown in fig. 6, the method further includes:
s601, determining whether the duration of the reverse mode executed by the heat dissipating component exceeds the second duration.
In the process that the heat dissipation component executes the reverse mode to remove dust from a component inside the electronic device, such as a processor, it is further determined whether the duration of the reverse mode executed by the heat dissipation component exceeds the second duration, where the second duration may be 20 seconds, for example.
And S602, when the duration time exceeds the second duration time, switching the heat dissipation component from a reverse rotation mode to a forward rotation mode based on the system information.
In this step, when the duration of time for which the heat radiating member executes the reverse rotation mode exceeds the second duration, for example, exceeds 20 seconds, the heat radiating member is switched from the reverse rotation mode to the normal rotation mode based on the system information. Therefore, the heat radiating component can be switched to the forward rotation mode only when the reverse rotation mode needs to be executed for a certain time, so that the dust removing effect of the heat radiating component is ensured, and the internal components of the electronic equipment cannot have more impurities such as dust.
And S104, switching the heat dissipation component from a reverse rotation mode to a forward rotation mode based on the system information.
In step S103, after the system information is acquired during the reverse rotation mode of the heat dissipating component, the rotation mode of the heat dissipating component is switched based on the system information, specifically, the heat dissipating component is switched from the reverse rotation mode to the forward rotation mode, that is, during the reverse rotation mode of the heat dissipating component, the rotation mode of the heat dissipating component can be dynamically adjusted according to the change of system load information and/or environmental temperature information based on the system information, and the reverse rotation mode in which dust removal is implemented is switched to the forward rotation mode in which heat dissipation is implemented, so that the heat dissipating component is reasonably controlled to switch from performing dust removal operation to heat dissipation operation under a certain condition.
As shown in fig. 7, the switching of the heat dissipation member from the reverse rotation mode to the forward rotation mode based on the system information includes:
s701, determining a second output duty of the heat sink based on the system information.
On the basis of obtaining the system information, in this step, a second output duty cycle of the heat dissipation component is first determined, where the output duty cycle refers to a ratio of time in which an electrical signal is output in a periodic electrical signal to a whole signal period, and the second output duty cycle is determined based on the system information, for example, system load information and/or ambient temperature information may be used as variables, and a mapping relationship is established between the second output duty cycle and the second output duty cycle.
S702, when the second output duty ratio is larger than a second threshold value, switching the heat dissipation component from the reverse rotation mode to the forward rotation mode.
On the basis that the second output duty ratio of the heat dissipation component is determined in step S701, the second output duty ratio is compared with a second threshold, and when the second output duty ratio is greater than the second threshold, that is, the ratio of the rotation control signal is high, that is, the requirement for dust removal of the heat dissipation component is low, at this time, switching of the heat dissipation component from the reverse rotation mode to the forward rotation mode may be performed to switch from meeting the requirement for dust removal of the electronic device internal component to meeting the heat dissipation requirement of the electronic device internal component.

The heat dissipation component according to the embodiment of the present disclosure may dissipate heat of the electronic device through a set mode, for example, the steps S101 to S104 are a dynamic operation mode, the heat dissipation component may implement a heat dissipation operation on a component such as a processor in the electronic device by executing the forward rotation mode, and may also implement a dust removal operation on a component such as a processor in the electronic device by executing the reverse rotation mode, in the dynamic operation mode, durations of the forward rotation mode and the reverse rotation mode may be adjusted based on the system information, so as to implement a heat dissipation operation or a dust removal operation dynamically, and further implement periodic dust removal for an indefinite period of time. Of course, the set mode may include a stable operation mode besides the dynamic operation mode, in the stable operation mode, the forward rotation mode and the reverse rotation mode are periodically executed according to the respective designated time, and further the periodic dust removal with a fixed time length is realized.
The operation mode of the heat dissipation component can be selected by a user as required, and therefore, before the system information is acquired in the process that the heat dissipation component executes the forward rotation mode, the method further comprises the following steps: determining operation modes of the heat dissipation part based on a selection instruction, wherein the operation modes at least comprise a dynamic operation mode and a stable operation mode; the selection instruction can be sent by the user in any way and received by the control device of the heat dissipation component to indicate the operation intention of the user; under the condition that the operation mode is a dynamic operation mode, acquiring system information to determine whether to convert the operation mode into a reverse rotation mode in the process that the heat dissipation component executes the forward rotation mode; in addition, when the operation mode is a steady operation mode, when the duration of the normal rotation mode or the reverse rotation mode executed by the heat radiating member reaches a predetermined time, the mode is automatically switched to another rotation mode, for example, the predetermined time of the normal rotation mode is 1 hour, the predetermined time of the reverse rotation mode is 20 seconds, the mode is automatically switched to the reverse rotation mode after the normal rotation mode is executed for 1 hour, and similarly, the mode is automatically switched to the normal rotation mode after the reverse rotation mode is executed for 20 seconds. Of course, the operation mode of the heat dissipation component may also include other modes, for example, a user needs to manually set the forward rotation mode or the reverse rotation mode to be switched, and the like.
