Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a heat dissipation control method, including:
when the target control signal is detected, determining a first operation scheme of the target radiator according to the target control signal, and executing the first operation scheme;
when the target control signal is not detected, a second operation scheme of the target radiator is executed, and the second operation scheme at least adapts to the current operation state of the system.
The method and the device have the advantages that the target radiator can be operated according to the first operation scheme when the target control signal is detected, and the target radiator can be operated according to the second operation scheme matched with the current system operation condition according to the current system operation condition when the target control signal is not detected, so that the output power of the target radiator is matched with the current system state, system energy consumption is not wasted, and the heat dissipation requirement of the system can be met. The phenomenon that the energy consumption of the system is wasted because the heat is radiated at the maximum radiating power when the target control signal is not detected no matter whether the current radiating requirement of the system is strong or not is avoided, or the phenomenon that the overall operation of the system is influenced because the heat cannot be timely radiated because the heat is radiated at the minimum radiating power is avoided.
Specifically, the second operation scheme in this embodiment at least includes an adjustment strategy of the output power of the target radiator, and before executing the second operation scheme of the target radiator, the system is further included or how the target radiator determines the second operation scheme (that is, the execution subject for determining the second operation scheme may be the system, and may also be the target radiator), and since the determination of the second operation scheme may be determined according to various different factors, that is, the determination manner is not unique, in order to better explain the determination manner, the following is described in detail with reference to different embodiments:
as shown in fig. 2, in the first embodiment:
determining the heat parameters and the load state of the system according to the running state of the system;
a second operating profile is determined based on the thermal parameter and the load condition.
For example, taking the target control signal as the PWM signal, when the PWM signal is detected by the system or the target radiator, the first operation scheme is determined according to the PWM signal, and the scheme is operated. When the system or the target radiator does not detect the PWM signal, the current operation state of the whole system is first determined, for example, whether the system is currently in a standby state, a sleep state, a normal operation state or a high-load operation state, then the current thermal parameter of the system, that is, the current heat generation amount of each heating device in the system, is determined based on the determined operation state information, and the current load state of the system is determined, which may also be determined by the heat generation amount. For example, the current heat production rate is matched with heat parameter thresholds representing different load levels, so as to determine the current load state of the system. Of course, the load state may be directly analyzed through the operation state information, or the load state may not be determined, only the thermal parameter may be determined, or only the load state may be determined, and the thermal parameter may not be determined, which is specific and not unique, and may be determined according to the actual situation. After the current heat parameter and the load state of the system are determined, the target radiator can determine an adjustment strategy of the output power of the target radiator according to the heat parameter and the load state, for example, if the heat parameter and the load state indicate that the current heat production of the system is large, the adjustment strategy is to improve the output power so as to adapt to the heat production state of the current system. And if the heat parameter and the load state indicate that the current heat production of the system is low, the adjustment strategy is to reduce the output power, so that the heat dissipation capacity of the radiator is reduced, and the energy consumption of the system is reduced.
As shown in fig. 3, the second embodiment:
determining the current energy consumption state of the system;
a second operating scenario that satisfies the energy consumption criteria is determined based on the current energy consumption state.
For example, the target control signal is a PWM signal, and when the PWM signal is not detected by the system or the target radiator, the current overall power consumption state of the system is determined immediately. Because the energy consumption of the system of each electronic device has a rated value, after the current energy consumption state of the system is determined, an energy consumption value matched with the current energy consumption state is obtained, and an available energy consumption value or an available energy consumption amount which can be currently provided by the system for the radiator can be determined based on the comparison between the energy consumption value and the rated value. When the energy consumption value or amount is determined, the heat sink may determine a matching output power adjustment strategy based on the value. For example, the amount of energy that can be supplied to the heat sink is higher, which increases the output power and decreases the output power. Of course, no matter how the adjustment is made, it is determined in combination with the rated power of the radiator.
In addition, when the output power is adjusted based on the energy consumption state, the final adjustment strategy can be determined by combining one or more of the current operation state, the heat parameter and the load state of the system in the first embodiment. That is, the final adjustment strategy can be matched with the current operation state of the system within the allowable range of the residual energy consumption.
As shown in fig. 4, example three:
determining a heating element matched with a target radiator;
the second operating scheme is determined in accordance with the different heating elements.
For example, the electronic device in this embodiment has a plurality of heat sinks, and the plurality of heat sinks respectively dissipate heat for the plurality of heat generating elements. For example, each heating element has at least one corresponding heat sink for dissipating heat therefrom. Assuming that the target control signal is a PWM signal, when the system or the target heat sink does not detect the signal, the system or each heat sink may determine the heating element corresponding to each heat sink, and then respectively and correspondingly determine a second operation scheme of each target heat sink based on the detected current operation state, heat generation state, etc. of each heating element obtained from the outside, wherein the second operation scheme matches the current operation state of the heating element corresponding to each target heat sink. For example, the heating element corresponding to the first heat sink is a CPU, and if the current CPU is in a high-speed operation state, the output power of the first heat sink needs to be increased to heat the heat dissipation amount, and if the current CPU is not in the high-speed operation state, the output power is reduced to reduce the heat dissipation amount, thereby avoiding excessive energy consumption.
Similarly, the determining manner of the second operation scheme in this embodiment may also be combined with the elements in the second embodiment to determine the second operation scheme, so that the finally determined second operation scheme can simultaneously meet the remaining energy consumption requirement and the heat dissipation requirement of the heating element.
As shown in fig. 5, example four:
determining a noise standard meeting the environment;
the second operating scheme is determined based on the noise criteria.
For example, the radiator generates a certain noise when operating, and the more the output power is increased, the more noise it generates. Therefore, in order to avoid the heat sink generating a large noise to affect the user in the surrounding environment, in this embodiment, when the system or the heat sink does not detect the target control signal, such as the PWM signal, the noise value characterizing the surrounding environment is actively detected or obtained from the external device, and the matching noise standard is determined based on the obtained noise value, such as performing matching search in the existing noise standard set, or determining through a network. Then, based on the noise standard, the current output power is determined to be suitable for the current environment, and the generated noise does not affect other people.
Similarly, in the present embodiment, when determining the second operation scheme, one or more elements in the first, second, and third embodiments may also be simultaneously combined to perform the determination, so as to ensure that the current operation scheme does not generate a large noise to affect surrounding users, and can also meet the heat dissipation requirements of the system or the heating element, and at the same time, no energy consumption is wasted.
Further, in this embodiment, when executing the second operation scheme of the target radiator, the second operation scheme at least adapts to the current operation of the system, including:
and determining the running rotating speed of the cooling fan according to the current running state of the system.
That is, the target heat sink in this embodiment is a heat dissipation fan, and the output power of the target heat sink is actually used to adjust the rotation speed of the heat dissipation fan, for example, to increase the output power to increase the rotation speed of the fan, or to decrease the rotation speed of the fan. Of course, the specific form of the heat sink is not exclusive, i.e. not just a fan, but may also be another type of heat sink.
Further, in this embodiment, after the target radiator executes the second operation scheme, when it is determined that the target control signal is detected:
and switching the operation scheme of the target radiator to be the first operation scheme determined according to the target control signal.
That is, the system or the target radiator may detect the target control signal in real time or at regular time, and if the target control signal is detected, for example, a PWM signal, the operation scheme may be re-determined immediately according to the PWM signal, that is, the first operation scheme may be re-drawn, and the target radiator may be operated based on the newly drawn first operation scheme instead of the current second operation scheme.
As shown in fig. 6, an embodiment of the present application also provides an electronic device, where the electronic device includes:
a heat sink;
the controller is used for determining a first operation scheme of the target radiator according to the target control signal and executing the first operation scheme when the target control signal is detected; when the target control signal input is not detected, a second operation scheme of the target radiator is executed, wherein the second operation scheme at least adapts to the current operation state of the system.
The method and the device have the advantages that the target radiator can be operated according to the first operation scheme when the target control signal is detected, and the target radiator can be operated according to the second operation scheme matched with the current system operation condition according to the current system operation condition when the target control signal is not detected, so that the output power of the target radiator is matched with the current system state, system energy consumption is not wasted, and the heat dissipation requirement of the system can be met. The phenomenon that the energy consumption of the system is wasted because the heat is radiated at the maximum radiating power when the target control signal is not detected no matter whether the current radiating requirement of the system is strong or not is avoided, or the phenomenon that the overall operation of the system is influenced because the heat cannot be timely radiated because the heat is radiated at the minimum radiating power is avoided.
Specifically, the controller in this embodiment may be a separate device, or may be provided in the heat sink. In addition, the second operation scheme in this embodiment at least includes an adjustment strategy of the output power of the target radiator, and before the second operation scheme of the target radiator is executed, how the controller determines the second operation scheme is further included, and since the determination of the second operation scheme may be determined according to various different factors, that is, the determination method is not unique, in order to better explain the determination method, the following detailed description is given in conjunction with different embodiments:
the first embodiment is as follows:
the controller, prior to executing the second operating scenario of the target radiator, is further configured to:
determining the running state of the system;
the second operating scheme is determined based on the operating state of the system.
For example, the following are:
determining the heat parameters and the load state of the system according to the running state of the system;
a second operating profile is determined based on the thermal parameter and the load condition.
For example, taking the target control signal as the PWM signal as an example, when the controller detects the PWM signal, the first operation scheme is determined according to the PWM signal and the scheme is operated. When the controller does not detect the PWM signal, the current operation state of the whole system is first determined, for example, whether the system is currently in a standby state, a sleep state, a normal operation state or a high-load operation state, then the current heat parameter of the system, that is, the current heat generation amount of each heating device in the system is determined based on the determined operation state information, and the current load state of the system is determined, which may also be determined by the heat generation amount. For example, the current heat production rate is matched with heat parameter thresholds representing different load levels, so as to determine the current load state of the system. Of course, the load state may be directly analyzed through the operation state information, or the load state may not be determined, only the thermal parameter may be determined, or only the load state may be determined, and the thermal parameter may not be determined, which is specific and not unique, and may be determined according to the actual situation. After the current heat parameter and the load state of the system are determined, the target radiator can determine an adjustment strategy of the output power of the target radiator according to the heat parameter and the load state, for example, if the heat parameter and the load state indicate that the current heat production of the system is large, the adjustment strategy is to improve the output power so as to adapt to the heat production state of the current system. And if the heat parameter and the load state indicate that the current heat production of the system is low, the adjustment strategy is to reduce the output power, so that the heat dissipation capacity of the radiator is reduced, and the energy consumption of the system is reduced.
Example two:
the controller is further configured to:
determining the current energy consumption state of the system;
a second operating scenario that satisfies the energy consumption criteria is determined based on the current energy consumption state.
For example, the target control signal is a PWM signal, and when the PWM signal is not detected by the controller, the current overall power consumption state of the system is determined immediately. Because the energy consumption of the system of each electronic device has a rated value, after the current energy consumption state of the system is determined, an energy consumption value matched with the current energy consumption state is obtained, and an available energy consumption value or an available energy consumption amount which can be currently provided by the system for the radiator can be determined based on the comparison between the energy consumption value and the rated value. When the energy consumption value or amount is determined, the heat sink may determine a matching output power adjustment strategy based on the value. For example, the amount of energy that can be supplied to the heat sink is higher, which increases the output power and decreases the output power. Of course, no matter how the adjustment is made, it is determined in combination with the rated power of the radiator.
In addition, when the output power is adjusted based on the energy consumption state, the final adjustment strategy can be determined by combining one or more of the current operation state, the heat parameter and the load state of the system in the first embodiment. That is, the final adjustment strategy can be matched with the current operation state of the system within the allowable range of the residual energy consumption.
Example three:
the controller is further configured to:
determining a heating element matched with a target radiator;
the second operating scheme is determined in accordance with the different heating elements.
For example, the electronic device in this embodiment has a plurality of heat sinks, and the plurality of heat sinks respectively dissipate heat for the plurality of heat generating elements. For example, each heating element has at least one corresponding heat sink for dissipating heat therefrom. Assuming that the target control signal is a PWM signal, when the controller does not detect the PWM signal, the controller may determine the heating element corresponding to each radiator, and then determine the second operation scheme of each target radiator based on the detected current operation state, heat generation state, etc. of each heating element obtained from the outside, respectively. Wherein the second operation scheme matches the current operation state of the heating element corresponding to each target radiator. For example, the heating element corresponding to the first heat sink is a CPU, and if the current CPU is in a high-speed operation state, the output power of the first heat sink needs to be increased to heat the heat dissipation amount, and if the current CPU is not in the high-speed operation state, the output power is reduced to reduce the heat dissipation amount, thereby avoiding excessive energy consumption.
Similarly, the determining manner of the second operation scheme in this embodiment may also be combined with the elements in the second embodiment to determine the second operation scheme, so that the finally determined second operation scheme can simultaneously meet the remaining energy consumption requirement and the heat dissipation requirement of the heating element.
Example four:
the controller is further configured to:
determining a noise standard meeting the environment;
the second operating scheme is determined based on the noise criteria.
For example, the radiator generates a certain noise when operating, and the more the output power is increased, the more noise it generates. Therefore, in order to avoid the heat sink generating a large noise to affect the user in the surrounding environment, in this embodiment, when the controller does not detect the target control signal, such as the PWM signal, it actively detects or obtains the noise value representing the surrounding environment from the external device, and determines the matching noise standard based on the obtained noise value, such as performing matching search in the existing noise standard set, or determining through a network. Then, based on the noise standard, the current output power is determined to be suitable for the current environment, and the generated noise does not affect other people.
Similarly, in the present embodiment, when determining the second operation scheme, one or more elements in the first, second, and third embodiments may also be simultaneously combined to perform the determination, so as to ensure that the current operation scheme does not generate a large noise to affect surrounding users, and can also meet the heat dissipation requirements of the system or the heating element, and at the same time, no energy consumption is wasted.
Further, in this embodiment, the target heat sink is a cooling fan, and when the controller executes a second operation scheme of the target heat sink, where the second operation scheme at least adapts to the current operation of the system, the specific steps are as follows:
and determining the running rotating speed of the cooling fan according to the current running state of the system.
That is, in the embodiment, the output power of the target heat sink is actually used to adjust the rotation speed of the heat dissipation fan, for example, the output power is increased to increase the rotation speed of the fan, and conversely, the rotation speed of the fan is decreased. Of course, the specific form of the heat sink is not exclusive, i.e. not just a fan, but may also be another type of heat sink.
Further, in this embodiment, when it is determined that the target control signal is detected after the target radiator executes the second operation scheme, the controller is further configured to:
and switching the operation scheme of the target radiator to be the first operation scheme determined according to the target control signal.
That is, the controller may detect the target control signal in real time or at regular time, and if the target control signal is detected, for example, the target control signal is a PWM signal, the controller may immediately re-determine the operation scheme according to the PWM signal, i.e., re-establish the first operation scheme, and replace the current second operation scheme, so that the target radiator operates based on the newly established first operation scheme.
