Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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.
As shown in fig. 1, an embodiment of the present invention provides an electronic device, which mainly includes: the main structures and the connection relationships of the housing 10, the heat generating device 20, the heat dissipation fan 30, the heat dissipation air duct 40, the air pressure sensor 50 and the processor 60 will be described in detail below.
The housing 10 has a receiving cavity (not shown) therein, and the receiving cavity can be used for receiving the heat generating device 20, the heat dissipation fan 30, the processor 60 and other components, and the specific shape and structure of the receiving cavity are not limited in this embodiment.
The heat generating device 20 is installed in the housing 10, and may be installed in the accommodating chamber.
The heat dissipation fan 30 is rotatably installed in the accommodating cavity, the accommodating cavity has a heat dissipation air duct 40 therein, the heat dissipation air duct 40 is disposed adjacent to the heat generating device 20, and the heat dissipation air duct 40 has an air inlet 41 and an air outlet 42 respectively communicated with the external environment.
It should be noted that fig. 1 only schematically shows several components of the heat generating device 20, the heat dissipating fan 30 and the heat dissipating air duct 40, and in fact, the positions and structures of these components are not limited to fig. 1. For example, the overall trend of the heat dissipation air duct 40 may also be a curved shape, and the inner diameter thereof may also be variably distributed; for another example, the number of the heat radiation fans 30 is not limited to 1, and may be plural.
In the embodiment of the present invention, the heat dissipation fan 30 is usually located near the center of the whole trend of the heat dissipation air duct 40, and subsequently, the heat dissipation air duct from the air inlet 41 to the position of the heat dissipation fan 30 may be referred to as an air inlet duct, and the heat dissipation air duct from the heat dissipation fan 30 to the air outlet 42 may be referred to as an air outlet duct.
In this embodiment, the air pressure sensor 50 is installed in the air inlet duct of the heat dissipation duct 40, and is used for detecting the real-time air pressure in the heat dissipation duct 40.
In the embodiment shown in fig. 1, the air pressure sensor 50 is installed in the air inlet duct, and can detect the real-time air pressure in the air inlet duct. Optionally, in other embodiments, the air pressure sensor 50 may also be installed in the air outlet duct of the heat dissipation air duct 40, and may detect the real-time air pressure in the air outlet duct. Optionally, air pressure sensors may be disposed in both the air inlet duct and the air outlet duct of the heat dissipation duct 40, and detect real-time air pressure in the air inlet duct and real-time air pressure in the air outlet duct, so that the processor 60 may further perform averaging operation, weighted averaging operation, and the like on the obtained real-time air pressure.
The processor 60 is respectively connected to the heat generating device 20, the heat dissipation fan 30 and the air pressure sensor 50, and the processor 60 adjusts (e.g., increases, decreases or maintains) the rotation speed of the heat dissipation fan 30 according to the real-time air pressure detected by the air pressure sensor 50; meanwhile, the processor 60 controls the operation of the heat generating device 20 (e.g., does not increase or decrease the power of the heat generating device 20, or maintains the power of the heat generating device 20) according to the real-time air pressure detected by the air pressure sensor 50.
The processor 60 may specifically compare the detected real-time air pressure with a preset threshold, for example, compare the detected real-time air pressure in the air intake duct with the preset threshold; comparing the detected real-time air pressure in the air outlet duct with a preset threshold value; or, averaging the detected real-time air pressure in the air inlet duct and the detected real-time air pressure in the air outlet duct, and comparing the average value with a preset threshold value.
Optionally, if the real-time air pressure (including the real-time air pressure in the air inlet duct, the real-time air pressure in the air outlet duct, and the average value, and the like) is greater than or equal to the first threshold, it is determined that the air outlet 42 (or the air outlet duct) of the heat dissipation duct 40 is blocked; alternatively, if the air pressure is less than or equal to a second threshold, it is determined that the air inlet 41 (or the air inlet duct) of the heat dissipation duct 40 is blocked, wherein the first threshold is greater than the second threshold.
Alternatively, if the processor 60 determines that the cooling air duct 40 is blocked, the rotation speed of the cooling fan 30 is reduced in the case that the cooling air duct is blocked, so as to protect the cooling fan 30 and prevent the blades of the cooling fan 30 from being damaged.
Alternatively, considering that the heat dissipation air duct 40 is generally unlikely to be completely blocked, if the processor 60 determines that the heat dissipation air duct 40 is blocked, the rotation speed of the heat dissipation fan 30 is increased under the condition that the heat dissipation air duct 40 is blocked, so as to protect the heat generating device 20 and prevent the heat generating device 20 from being damaged due to overheating.
Alternatively, if the detected real-time air pressure is greater than the second threshold value but less than the first threshold value, i.e. within the normal threshold range, the processor 60 may determine that the cooling air duct 40 is not blocked, and then may maintain the rotation speed of the cooling fan 30 and the power of the heat generating device 20.
The first threshold and the second threshold mentioned above can be obtained specifically according to the real-time air pressure detected when the cooling fan 30 works normally, the cooling fan 30 at this position works normally, that is, the rotation speed of the cooling fan 30 is normal, and the air inlet duct (including the position of the air inlet 41) and the air outlet duct (including the position of the air outlet 42) are not blocked.
It should be noted that, in fig. 1, the heat generating device and the processor are shown separately, and in the practical application process, the heat generating device and the processor may also be integrated, for example, the processor is a main heat generating source of the electronic device, and the heat generating device is the processor itself.
The blocking of the air duct mentioned in the embodiments of the present specification may specifically be a blocking of dust accumulation, a blocking of fingers or clothes of a user, and the like.
Optionally, the processor 60 may also control the electronic device to issue a prompt in the event that it is determined that the cooling air duct 40 is blocked.
The embodiment may be an audible and visual prompt, or may be a UI interface prompt, for example, in the form of a notification message, an early warning dialog, etc.
Optionally, if it is determined that the air inlet 41 of the heat dissipation air duct 40 is completely or partially blocked, a warning dialog box pops up on the display interface of the electronic device to remind the user to clear the obstacle of the air inlet 41.
Optionally, if it is determined that the air outlet 42 of the heat dissipation air duct 40 is completely or partially blocked, a warning dialog box is popped up on the display interface of the electronic device to remind the user to clear the obstacle of the air outlet.
According to the electronic equipment provided by the embodiment of the invention, the real-time air pressure in the heat dissipation air channel is detected through the air pressure sensor arranged in the heat dissipation air channel, so that the processor can determine whether the heat dissipation air channel is blocked according to the real-time air pressure, adjust the rotating speed of the heat dissipation fan and control the heating device to work according to the determination result, and the problem that whether the heat dissipation air channel is blocked cannot be determined in the related technology is solved; meanwhile, a solution is provided for the working mechanism of the cooling fan and the heating device when the cooling air duct is blocked, and the effect of protecting the cooling fan or the heating device can be realized.
For example, when the heat dissipation duct is blocked: the processor reduces the rotating speed of the cooling fan to protect the cooling fan and prevent the fan blades of the cooling fan from being damaged; the processor increases the rotating speed of the cooling fan to protect the heating device and prevent the heating device from being damaged due to overheating.
For another example, in the case that the heat dissipation air duct is blocked, the processor does not increase or decrease the power of the heat generating device, so as to protect the heat generating device and prevent the heat generating device from being damaged due to overheating.
The electronic equipment provided by the embodiment of the invention can greatly reduce the problems of deteriorated heat dissipation performance, increased system power consumption, damaged fan service life and the like of the electronic equipment caused by blockage of the heat dissipation air duct, is more humanized and is convenient for improving the difference and reputation of the electronic equipment.
In the above embodiment, when the processor 60 determines whether the cooling air duct 40 is blocked, the detected real-time air pressure is compared with the first threshold and the second threshold, optionally, in order to improve the accuracy of determining whether the cooling air duct is blocked and reduce the probability of misjudgment as much as possible, in this embodiment, the processor 60 may further adjust the first threshold and the second threshold according to at least one of the following:
1) atmospheric pressure at the location of the electronic device.
For a user in a high altitude area, the atmospheric pressure at the location of the electronic device is generally low, for example, lower than the standard atmospheric pressure value, and the first threshold value and the second threshold value may be appropriately lowered; for a user in a low altitude area, the atmospheric pressure at the location of the electronic device is generally higher, for example, higher than the standard atmospheric pressure value, and the first threshold value and the second threshold value may be appropriately increased.
In a preferred embodiment, the electronic device further includes a storage module (not shown) connected to the processor 60, and the storage module stores the atmospheric pressure and the correspondence table between the first threshold and the second threshold, and the optimal values of the first threshold and the second threshold under the current atmospheric pressure can be quickly determined by looking up the table.
Optionally, the electronic device shown in fig. 1 further includes a positioning module (not shown), which is installed in the housing 10 and is used for detecting the position of the electronic device; the processor 60 is connected to the positioning module, and the processor 60 further determines an altitude of a location where the electronic device is located according to the location where the electronic device is located, determines an atmospheric pressure of the location where the electronic device is located according to the altitude, and adjusts the first threshold and the second threshold according to the atmospheric pressure of the location where the electronic device is located.
2) The rotational speed of the cooling fan 30.
It can be understood that the faster the rotation speed of the cooling fan 30 is, the smaller the air pressure in the cooling air duct 40 is, and conversely, the slower the rotation speed of the cooling fan 30 is, the larger the air pressure in the cooling air duct 40 is, so that this embodiment can appropriately reduce the first threshold value and the second threshold value when the rotation speed of the cooling fan 30 is detected to be faster; when it is detected that the rotation speed of the heat dissipation fan 30 is slow, the first threshold value and the second threshold value are appropriately increased.
In this embodiment, the processor 60 may determine the rotational speed of the cooling fan 30 by the power of the cooling fan 30.
In a preferred embodiment, the electronic device further includes a storage module (not shown) connected to the processor 60, the storage module stores therein the rotation speed of the cooling fan 30 and the correspondence table between the first threshold and the second threshold, and the optimal values of the first threshold and the second threshold at the current rotation speed of the cooling fan 30 can be quickly determined by looking up the table.
3) The temperature within the cooling air duct 40.
It can be understood that, the higher the temperature in the cooling air duct 40 is, the lower the air pressure in the cooling air duct 40 is, whereas, the lower the temperature in the cooling air duct 40 is, the higher the air pressure in the cooling air duct 40 is, therefore, this embodiment can suitably reduce the first threshold and the second threshold when detecting that the temperature in the cooling air duct 40 is high; when the temperature in the heat dissipation air duct 40 is detected to be low, the first threshold value and the second threshold value are appropriately increased.
In a preferred embodiment, the electronic device further includes a storage module (not shown) connected to the processor 60, the storage module stores a table of correspondence between the temperature in the cooling air duct 40 and the first threshold and the second threshold, and the optimal value of the first threshold and the second threshold at the current temperature of the cooling air duct 40 can be quickly determined by looking up the table.
Optionally, the electronic device shown in fig. 1 further includes a temperature sensor 70, where the temperature sensor 70 is installed in the heat dissipation air duct 40 and is configured to detect a real-time temperature in the heat dissipation air duct 40; the processor 60 is connected to the temperature sensor 70 and the processor also adjusts the first threshold and the second threshold based on the real-time temperature.
Alternatively, the processor 60 may also adjust the rotation speed of the cooling fan 30 according to the real-time temperature detected by the temperature sensor 70 and the real-time air pressure detected by the air pressure sensor 50; the processor 60 controls the operation of the heat generating device 20 according to the real-time temperature detected by the temperature sensor 70 and the real-time air pressure detected by the air pressure sensor 50.
Specifically, for example, if the real-time air pressure is greater than or equal to the first threshold and the real-time temperature gradually increases, it is determined that the air outlet of the heat dissipation air duct is blocked, the rotation speed of the heat dissipation fan 30 is reduced or increased, and the power of the heat generating device 20 is not increased or reduced; for another example, if the real-time air pressure is less than or equal to the second threshold and the real-time temperature gradually increases, it is determined that the air inlet of the air duct is blocked, the rotation speed of the heat dissipation fan 30 is reduced or increased, and the power of the heat generating device 20 is not increased or reduced.
In the embodiment, the rotation speed of the cooling fan is reduced mainly for protecting the cooling fan, preventing the fan blades of the cooling fan from being damaged and reducing the power consumption of the electronic equipment; the rotation speed of the cooling fan is increased to protect the heating device and increase the cooling performance.
According to the embodiment, the change of the real-time temperature in the heat dissipation air duct is detected, so that the accuracy of determining whether the heat dissipation air duct is blocked can be improved, the probability of misjudgment is reduced as much as possible, and the user experience is improved.
Optionally, the processor 60 further adjusts the rotation speed of the heat dissipation fan 30 according to the real-time temperature detected by the temperature sensor 70, the real-time air pressure detected by the air pressure sensor 50, and the power of the heat generating device 20; the processor 60 controls the operation of the heat generating device 20 according to the real-time temperature detected by the temperature sensor 70, the real-time air pressure detected by the air pressure sensor 50, and the power of the heat generating device 20.
Specifically, for example, if the real-time air pressure is greater than or equal to the first threshold, the real-time temperature gradually increases, and the power of the heat generating device 20 is lower than the preset threshold, it is determined that the air outlet of the heat dissipation air duct is blocked, the rotation speed of the heat dissipation fan 30 is reduced or increased, and the power of the heat generating device 20 is not increased or reduced; for another example, if the real-time air pressure is less than or equal to the second threshold, the real-time temperature gradually increases, and the power of the heat generating device 20 is lower than the preset threshold, it is determined that the air inlet of the heat dissipation air duct is blocked, the rotation speed of the heat dissipation fan 30 is reduced or increased, and the power of the heat generating device 20 is not increased or reduced.
In the embodiment, the rotation speed of the cooling fan is reduced mainly for protecting the cooling fan, avoiding damage to the fan blades of the cooling fan and reducing power consumption of the electronic equipment; the rotation speed of the cooling fan is increased to protect the heating device and increase the cooling performance.
According to the embodiment, the accuracy of determining whether the air channel is blocked can be further improved by detecting the real-time temperature change and the power condition of the heating device, the probability of misjudgment is reduced as much as possible, and the user experience is improved.
