Description

Technical Field

[0001] The present invention relates to the field of thermal management technology, and in particular to a thermal management method and system for electronic devices, electronic equipment, and a computer-readable storage medium. Background Art

[0002] With the development of portable devices and integrated devices, the use of electronic devices is increasing. With the high-frequency use or long-term operation of the equipment, the heat generated by the electronic devices will gradually increase. When the electronic devices generate severe heat, their lifespan will be shortened, their performance will decline, and their response speed will become slower, which will in turn reduce the overall reliability of the electronic devices.

[0003] Considering that core electronic devices such as chips and batteries will generate a lot of heat during operation, temperature detection elements and heat dissipation elements are usually configured in electronic devices at present. The temperature detection element is used to detect the operating temperature of the electronic device, and the heat dissipation element, such as a fan heat sink, a water-cooled heat sink, etc., is used to cool and dissipate the heat of the heated electronic device to avoid the operating temperature of the electronic device being too high and causing it to burn out. However, in the prior art, there is a thermal resistance problem between the temperature detection element and the electronic device, resulting in a certain lag in the device operating temperature detected by the temperature detection element. When the operating state of the electronic device suddenly changes, the operating temperature of the electronic device may also change rapidly, and the temperature detection element cannot reflect the actual temperature of the electronic device in real time and quickly, that is, the real-time detection temperature of the temperature detection element is different from the actual operating temperature of the electronic device, so that the heat dissipation efficiency of the heat dissipation element cannot be adjusted in time, affecting the operating safety of the electronic device when it is heated.

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0078] See also Figure 1 According to a first aspect of an embodiment of the present invention, a thermal management method for an electronic device is provided, comprising the following steps S1 and S2:

[0079] Step S1, acquiring a first real-time electrical parameter of a first temperature sensor and a second real-time electrical parameter of a second temperature sensor;

[0080] Step S2, adjusting the operating power of the heat dissipation module according to the first real-time electrical parameter, the second real-time electrical parameter, and a preset first electrical parameter threshold corresponding to the first temperature sensor, so that the heat dissipation module dissipates heat for the target device based on the adjusted operating power;

[0081] Among them, the first real-time electrical parameter of the first temperature sensor has a mapping relationship with the real-time operating temperature of the target device, and the second real-time electrical parameter of the second temperature sensor has a mapping relationship with the real-time ambient temperature; the first temperature sensor is arranged on the surface of the target device, or the first temperature sensor is embedded in the circuit board or carrier board on which the target device is assembled.

[0082] It is worth noting that the temperature sensor is based on the temperature characteristics of the material. When the temperature changes, the resistance or potential inside the temperature sensing element will also change, thereby causing a change in the output electrical signal, such as a change in voltage, a change in current, a change in resistance, etc. Therefore, this embodiment characterizes the real-time operating temperature of the target device currently being detected by obtaining a first real-time electrical parameter of the first temperature sensor, and characterizes the current real-time ambient temperature by obtaining a second real-time electrical parameter of the second temperature sensor. Taking thermistors as an example, they can be divided into NTC (Negative Temperature Coefficient) thermistors and PTC (Positive Temperature Coefficient) thermistors according to different temperature coefficients. For NTC thermistors, their resistance values ​​will decrease as the temperature increases, and for PTC thermistors, their resistance values ​​will increase as the temperature increases. Therefore, different first real-time electrical parameters correspond to different real-time operating temperatures of the target device, that is, the first real-time electrical parameter of the first temperature sensor has a one-to-one mapping relationship with the real-time operating temperature of the target device, and different second real-time electrical parameters correspond to different real-time ambient temperatures, that is, the second real-time electrical parameter of the second temperature sensor has a one-to-one mapping relationship with the real-time ambient temperature. Based on this, this embodiment pre-sets the first electrical parameter threshold corresponding to the temperature sensor, and the real-time operating temperature corresponding to the first electrical parameter threshold indicates that the target device exceeds the normal operating temperature and needs to take heat dissipation and cooling measures. Among them, the ambient temperature can refer to the ambient temperature in the environment where the target device is located, and can also refer to the temperature of the medium that is in contact with the target device (contact includes direct contact and indirect contact) and can exchange heat with the target device.

[0083] In order to take heat dissipation and cooling measures in time, this embodiment needs to determine the control timing of the heat dissipation module based on the first real-time electrical parameter of the first temperature sensor and the preset first electrical parameter threshold. When the target device exceeds the normal operating temperature, it is necessary to control the heat dissipation module to start heat dissipation based on the first real-time electrical parameter. In addition, in order to accurately take heat dissipation and cooling measures, it is necessary to further adjust the operating power of the heat dissipation module based on the second real-time electrical parameter of the second temperature sensor. It can be understood that the second real-time electrical parameter represents the current real-time ambient temperature. When the real-time ambient temperature is low, the heat exchange efficiency between the target device, the heat dissipation module and the external environment is high. Therefore, the operating power of the heat dissipation module can be appropriately reduced to ensure the heat dissipation effect while saving the power consumption of the heat dissipation module as much as possible; when the real-time ambient temperature is high, the heat exchange efficiency between the target device, the heat dissipation module and the external environment is low. Therefore, it is necessary to appropriately increase the operating power of the heat dissipation module to ensure effective heat dissipation of the target device. Therefore, this embodiment can perform differential heat dissipation on the target device based on the difference in the real-time operating temperature of the target device and the difference in the real-time ambient temperature, effectively avoiding the occurrence of overheating of the target device.

[0084] In addition, the first temperature sensor in this embodiment can be directly arranged on the surface of the target device, so that the surface temperature of the target device can be directly detected, and feedback can be provided through the first real-time electrical parameter, which significantly improves the detection accuracy and real-time performance; the first temperature sensor can also be directly embedded in the circuit board or carrier board assembled with the target device, such as a substrate or PCB board. Compared with the traditional temperature detection element, the method of embedding in the circuit board or carrier board can make the distance between the first temperature sensor and the target device closer, thereby improving the detection accuracy and real-time performance. At the same time, the first temperature sensor is directly attached to the surface of the target device or embedded in the circuit board or carrier board assembled with the target device, which can reduce the volume of the entire thermal management system and facilitate the miniaturization of electronic equipment.

[0085] It is worth noting that due to the different temperature characteristics of different temperature sensors, the real-time operating temperature of the target device corresponding to different first real-time electrical parameters is different, and thus the corresponding first electrical parameter thresholds are also different. Therefore, this embodiment does not make specific limitations on the first electrical parameter threshold.

[0086] As a preferred embodiment, the first real-time electrical parameter is at least one of a first real-time voltage, a first real-time resistance and a first real-time current; the second real-time electrical parameter is at least one of a second real-time voltage, a second real-time resistance and a second real-time current; the first electrical parameter threshold is at least one of a first voltage threshold, a first resistance threshold and a first current threshold.

[0087] It is worth noting that the present embodiment can characterize the real-time operating temperature of the target device by obtaining at least one of the first real-time voltage, the first real-time resistance and the first real-time current. It can be understood that the real-time operating temperatures of the target device corresponding to the first voltage threshold, the first resistance threshold and the first current threshold are all abnormal operating temperature thresholds of the target device. If the first real-time voltage is obtained, the corresponding first voltage threshold is used to detect the real-time operating temperature of the target device. If the first real-time voltage does not meet the first voltage threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time voltage is higher than or equal to the real-time operating temperature of the target device corresponding to the first voltage threshold, it means that the current operating temperature of the target device has reached the abnormal operating temperature threshold and is in an abnormal temperature state, requiring heat dissipation. If the first real-time resistance is obtained, the corresponding first resistance threshold is used to detect the real-time operating temperature of the target device. If the first real-time resistance does not meet the first resistance threshold, that is, the target device corresponding to the first real-time resistance If the real-time operating temperature of the target device is higher than or equal to the real-time operating temperature of the target device corresponding to the first resistance threshold, it means that the operating temperature of the current target device has reached the abnormal operating temperature threshold, is in an abnormal temperature state, and needs to be cooled; if the first real-time current is obtained, the corresponding first current threshold is used to detect the real-time operating temperature of the target device. If the first real-time current does not meet the first current threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time current is higher than or equal to the real-time operating temperature of the target device corresponding to the first current threshold, it means that the operating temperature of the current target device has reached the abnormal operating temperature threshold, is in an abnormal temperature state, and needs to be cooled.

[0088] In addition, the present embodiment can also characterize the real-time ambient temperature conditions by obtaining at least one of a second real-time voltage, a second real-time resistance, and a second real-time current. In the actual thermal management process, based on the conditions for obtaining electrical parameters, voltage parameters, resistance parameters and / or current parameters can be selectively obtained. This embodiment is not specifically limited here, thereby significantly improving the versatility of the embodiments of the present invention.

[0089] As a preferred solution, the operating power of the heat dissipation module is adjusted according to the first real-time electrical parameter, the second real-time electrical parameter and the preset first electrical parameter threshold value corresponding to the first temperature sensor, specifically including:

[0090] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a first real-time current, the first electrical parameter threshold is a first current threshold, and the first real-time electrical parameter is greater than or equal to the first electrical parameter threshold, the heat dissipation module is controlled to operate in a low power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0091] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a first real-time voltage, the first electrical parameter threshold is a first voltage threshold, and the first real-time electrical parameter is less than or equal to the first electrical parameter threshold, controlling the heat dissipation module to operate in a low power mode, and adjusting the operating power of the heat dissipation module according to the second real-time electrical parameter;

[0092] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a first real-time resistor, the first electrical parameter threshold is a first resistance threshold, and the first real-time electrical parameter is less than or equal to the first electrical parameter threshold, controlling the heat dissipation module to operate in a low power mode, and adjusting the operating power of the heat dissipation module according to the second real-time electrical parameter;

[0093] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a first real-time current, the first electrical parameter threshold is a first current threshold, and the first real-time electrical parameter is less than or equal to the first electrical parameter threshold, the heat dissipation module is controlled to operate in a low power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0094] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a first real-time voltage, the first electrical parameter threshold is a first voltage threshold, and the first real-time electrical parameter is greater than or equal to the first electrical parameter threshold, the heat dissipation module is controlled to operate in a low power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0095] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a first real-time resistor, the first electrical parameter threshold is a first resistance threshold, and the first real-time electrical parameter is greater than or equal to the first electrical parameter threshold, the heat dissipation module is controlled to operate in a low power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0096] Wherein, the operating power of the heat dissipation module in the low power mode is less than 1 / 2 of the maximum operating power.

[0097] It is worth noting that for NTC thermistors, based on their negative temperature coefficient characteristics and Ohm's law, when the temperature of the detection object increases, their resistance and output voltage will decrease as the temperature increases, while the current flowing through the NTC thermistor will increase as the temperature increases.

[0098] Therefore, when the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a current parameter, and the first electrical parameter threshold is also a current parameter, if the first real-time current is greater than or equal to the first current threshold, it indicates that the real-time operating temperature of the target device continues to rise to the abnormal temperature threshold, or exceeds the abnormal temperature threshold, causing the first real-time current of the NTC thermistor to continue to rise to the first current threshold, or exceed the first current threshold.

[0099] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a voltage parameter, and the first electrical parameter threshold is also a voltage parameter, if the first real-time voltage is less than or equal to the first voltage threshold, it indicates that the real-time operating temperature of the target device continues to rise to the abnormal temperature threshold, or exceeds the abnormal temperature threshold, causing the first real-time voltage output by the NTC thermistor to continue to drop to the first voltage threshold, or be less than the first voltage threshold.

[0100] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a resistance parameter, and the first electrical parameter threshold is also a resistance parameter, if the first real-time resistance is less than or equal to the first resistance threshold, it indicates that the real-time operating temperature of the target device continues to rise to the abnormal temperature threshold, or exceeds the abnormal temperature threshold, causing the first real-time resistance of the NTC thermistor to continue to drop to the first resistance threshold, or be less than the first resistance threshold.

[0101] For a PTC thermistor, based on its positive temperature coefficient characteristics and Ohm's law, when the temperature of the detection object increases, its resistance and output voltage will increase with the temperature, while the current flowing through the PTC thermistor will decrease with the temperature.

[0102] Therefore, when the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a current parameter, and the first electrical parameter threshold is also a current parameter, if the first real-time current is less than or equal to the first current threshold, it indicates that the real-time operating temperature of the target device continues to rise to the abnormal temperature threshold, or exceeds the abnormal temperature threshold, causing the first real-time current of the PTC thermistor to continue to drop to the first current threshold, or be less than the first current threshold.

[0103] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a voltage parameter, and the first electrical parameter threshold is also a voltage parameter, if the first real-time voltage is greater than or equal to the first voltage threshold, it indicates that the real-time operating temperature of the target device continues to rise to the abnormal temperature threshold, or exceeds the abnormal temperature threshold, causing the first real-time voltage output by the PTC thermistor to continue to rise to the first voltage threshold, or exceed the first voltage threshold.

[0104] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a resistance parameter, and the first electrical parameter threshold is also a resistance parameter, if the first real-time resistance is less than or equal to the first resistance threshold, it indicates that the real-time operating temperature of the target device continues to rise to the abnormal temperature threshold, or exceeds the abnormal temperature threshold, causing the first real-time resistance of the PTC thermistor to continue to rise to the first resistance threshold, or exceed the first resistance threshold.

[0105] Furthermore, when it is determined that the real-time operating temperature of the target device reaches or exceeds the abnormal temperature threshold, although the target device is overheated at this time, the degree of overheating is relatively mild. Therefore, the heat dissipation module can be controlled to operate in a low-power mode, thereby ensuring the heat dissipation effect while reducing the power loss of the heat dissipation module. In addition, the current real-time ambient temperature can be clearly determined based on the second real-time electrical parameter. In order to consider the impact of the real-time ambient temperature on the heat dissipation effect, this embodiment further adjusts the operating power of the heat dissipation module in the low-power mode according to the second real-time electrical parameter.

[0106] It is worth noting that when it is detected that the first real-time electrical parameter of the temperature sensor meets the first electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time electrical parameter is lower than the real-time operating temperature of the target device corresponding to the first electrical parameter threshold, the initial operating power of the heat dissipation module before adjusting the operating power is restored to avoid increased power consumption of the electronic device due to continuous high power output of the heat dissipation power.

[0107] As a preferred embodiment, the method further comprises:

[0108] adjusting the operating power of the heat dissipation module according to the first real-time electrical parameter, the second real-time electrical parameter, and a preset second electrical parameter threshold value corresponding to the first temperature sensor;

[0109] Among them, the real-time operating temperature of the target device corresponding to the second electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the first electrical parameter threshold; the second electrical parameter threshold is at least one of a second voltage threshold, a second resistance threshold and a second current threshold.

[0110] It is worth noting that after adjusting the operating power of the heat dissipation module, the target device may continue to generate heat due to reasons such as dust accumulation on the heat dissipation module affecting the heat dissipation effect, excessive ambient temperature, excessive software running load, etc., and the operating temperature continues to rise. In order to further avoid burning of the target device, this embodiment additionally sets a second electrical parameter threshold. It can be understood that the real-time operating temperature of the target device corresponding to the second electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the first electrical parameter threshold, that is, the second electrical parameter threshold indicates that the target device is currently at a higher abnormal operating temperature. When the acquired first real-time electrical parameter does not meet the second electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time electrical parameter is higher than or equal to the real-time operating temperature of the target device corresponding to the second electrical parameter threshold, it indicates that the heat dissipation efficiency of the current heat dissipation module is insufficient, and its operating power needs to be further increased to improve the heat dissipation effect on the target device.

[0111] The first real-time electrical parameter obtained in this embodiment is at least one of a first real-time voltage, a first real-time resistance and a first real-time current, so the second electrical parameter threshold is correspondingly set to at least one of a second voltage threshold, a second resistance threshold and a second current threshold.

[0112] It can be understood that if the first real-time voltage is obtained, the corresponding second voltage threshold is used to detect the real-time operating temperature of the target device. If the first real-time voltage does not meet the second voltage threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time voltage is higher than or equal to the real-time operating temperature of the target device corresponding to the second voltage threshold, then it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, and the heat dissipation efficiency of the heat dissipation module needs to be further improved.

[0113] If the first real-time resistance is obtained, the corresponding second resistance threshold is used to detect the real-time operating temperature of the target device. If the first real-time resistance does not meet the second resistance threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time resistance is higher than or equal to the real-time operating temperature of the target device corresponding to the second resistance threshold, it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, and the heat dissipation efficiency of the heat dissipation module needs to be further improved.

[0114] If the first real-time current is obtained, the corresponding second current threshold is used to detect the real-time operating temperature of the target device. If the first real-time current does not meet the second current threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time current is higher than or equal to the real-time operating temperature of the target device corresponding to the second current threshold, then it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, and the heat dissipation efficiency of the heat dissipation module needs to be further improved.

[0115] As a preferred solution, the operating power of the heat dissipation module is adjusted according to the first real-time electrical parameter, the second real-time electrical parameter and the preset second electrical parameter threshold value corresponding to the first temperature sensor, specifically including:

[0116] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a first real-time current, the second electrical parameter threshold is a second current threshold, and the first real-time electrical parameter is greater than or equal to the second electrical parameter threshold, the heat dissipation module is controlled to operate in a high power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0117] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a first real-time voltage, the second electrical parameter threshold is a second voltage threshold, and the first real-time electrical parameter is less than or equal to the second electrical parameter threshold, the heat dissipation module is controlled to operate in a high power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0118] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a first real-time resistance, the second electrical parameter threshold is a second resistance threshold, and the first real-time electrical parameter is less than or equal to the second electrical parameter threshold, the heat dissipation module is controlled to operate in a high power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0119] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a first real-time current, the second electrical parameter threshold is a second current threshold, and the first real-time electrical parameter is less than or equal to the second electrical parameter threshold, the heat dissipation module is controlled to operate in a high power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0120] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a first real-time voltage, the second electrical parameter threshold is a second voltage threshold, and the first real-time electrical parameter is greater than or equal to the second electrical parameter threshold, the heat dissipation module is controlled to operate in a high power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0121] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a first real-time resistance, the second electrical parameter threshold is a second resistance threshold, and the first real-time electrical parameter is greater than or equal to the second electrical parameter threshold, the heat dissipation module is controlled to operate in a high power mode, and the operating power of the heat dissipation module is adjusted according to the second real-time electrical parameter;

[0122] Wherein, the operating power of the heat dissipation module in the high power mode is greater than 1 / 2 of the maximum operating power.

[0123] It is worth noting that when the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a current parameter, and the second electrical parameter threshold is also a current parameter, if the first real-time current is greater than or equal to the second current threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time current of the NTC thermistor to continue to rise to the second current threshold, or exceed the second current threshold.

[0124] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a voltage parameter, and the second electrical parameter threshold is also a voltage parameter, if the first real-time voltage is less than or equal to the second voltage threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time voltage output by the NTC thermistor to continue to drop to the second voltage threshold, or be less than the second voltage threshold.

[0125] When the first temperature sensor is an NTC thermistor, the first real-time electrical parameter is a resistance parameter, and the second electrical parameter threshold is also a resistance parameter, if the first real-time resistance is less than or equal to the second resistance threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time resistance of the NTC thermistor to continue to drop to the second resistance threshold, or be less than the second resistance threshold.

[0126] In addition, when the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a current parameter, and the second electrical parameter threshold is also a current parameter, if the first real-time current is less than or equal to the second current threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time current of the PTC thermistor to continue to drop to the second current threshold, or be less than the second current threshold.

[0127] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a voltage parameter, and the second electrical parameter threshold is also a voltage parameter, if the first real-time voltage is greater than or equal to the second voltage threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time voltage output by the PTC thermistor to continue to rise to the second voltage threshold, or exceed the second voltage threshold.

[0128] When the first temperature sensor is a PTC thermistor, the first real-time electrical parameter is a resistance parameter, and the second electrical parameter threshold is also a resistance parameter, if the first real-time resistance is greater than or equal to the second resistance threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time resistance of the PTC thermistor to continue to rise to the second resistance threshold, or exceed the second resistance threshold.

[0129] Furthermore, when it is determined that the real-time operating temperature of the target device reaches or exceeds a higher abnormal temperature threshold, it indicates that the current target device is seriously overheated, and therefore it is necessary to control the heat dissipation module to operate in a high-power mode to ensure the heat dissipation effect on the target device. In addition, the current real-time ambient temperature can be clearly determined based on the second real-time electrical parameter. In order to consider the impact of the real-time ambient temperature on the heat dissipation effect, this embodiment further adjusts the operating power of the heat dissipation module in the high-power mode according to the second real-time electrical parameter.

[0130] It is worth noting that when it is detected that the first real-time electrical parameter of the temperature sensor meets the second electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time electrical parameter is lower than the real-time operating temperature of the target device corresponding to the second electrical parameter threshold, but has not yet met the first electrical parameter threshold, the heat dissipation module can be restored to operate in low power mode to avoid increased power consumption of the electronic device due to continuous high power output of the heat dissipation power.

[0131] As a preferred solution, the adjusting the operating power of the heat dissipation module according to the second real-time electrical parameter specifically includes:

[0132] Acquire a third electrical parameter threshold corresponding to the second temperature sensor; wherein the third electrical parameter threshold is at least one of a third voltage threshold, a third resistance threshold, and a third current threshold;

[0133] When the second temperature sensor is an NTC thermistor, the second real-time electrical parameter is a second real-time current, and the third electrical parameter threshold is a third current threshold, if the second real-time current is greater than or equal to the third current threshold, the heat dissipation module is controlled to increase its operating power; if the second real-time current is less than the third current threshold, the heat dissipation module is controlled to reduce its operating power;

[0134] When the second temperature sensor is an NTC thermistor, the second real-time electrical parameter is a second real-time voltage, and the third electrical parameter threshold is a third voltage threshold, if the second real-time voltage is less than or equal to the third voltage threshold, the heat dissipation module is controlled to increase its operating power; if the second real-time voltage is greater than the third voltage threshold, the heat dissipation module is controlled to reduce its operating power;

[0135] When the second temperature sensor is an NTC thermistor, the second real-time electrical parameter is a second real-time resistor, and the third electrical parameter threshold is a third resistance threshold, if the second real-time resistance is less than or equal to the third resistance threshold, the heat dissipation module is controlled to increase its operating power; if the second real-time resistance is greater than the third resistance threshold, the heat dissipation module is controlled to reduce its operating power;

[0136] When the second temperature sensor is a PTC thermistor, the second real-time electrical parameter is a second real-time current, and the third electrical parameter threshold is a third current threshold, if the second real-time current is less than or equal to the third current threshold, the heat dissipation module is controlled to increase its operating power; if the second real-time current is greater than the third current threshold, the heat dissipation module is controlled to reduce its operating power;

[0137] When the second temperature sensor is a PTC thermistor, the second real-time electrical parameter is a second real-time voltage, and the third electrical parameter threshold is a third voltage threshold, if the second real-time voltage is greater than or equal to the third voltage threshold, the heat dissipation module is controlled to increase its operating power; if the second real-time voltage is less than the third voltage threshold, the heat dissipation module is controlled to reduce its operating power;

[0138] When the second temperature sensor is a PTC thermistor, the second real-time electrical parameter is a second real-time resistance, and the third electrical parameter threshold is a third resistance threshold, if the second real-time resistance is greater than or equal to the third resistance threshold, the heat dissipation module is controlled to increase its operating power; if the second real-time resistance is less than the third resistance threshold, the heat dissipation module is controlled to reduce its operating power.

[0139] Specifically, in order to accurately adjust the operating power of the heat dissipation module according to the second real-time electrical parameter, the present embodiment first obtains the third electrical parameter threshold corresponding to the second temperature sensor. It can be understood that the third electrical parameter threshold is used to characterize the current ambient temperature threshold. If the second real-time electrical parameter satisfies the third electrical parameter threshold, that is, the real-time ambient temperature corresponding to the second real-time electrical parameter is lower than the real-time ambient temperature corresponding to the third electrical parameter threshold, then it indicates that the current real-time ambient temperature is lower than the ambient temperature threshold, that is, the real-time ambient temperature is low; and if the second real-time electrical parameter does not satisfy the third electrical parameter threshold, that is, the real-time ambient temperature corresponding to the second real-time electrical parameter is higher than or equal to the real-time ambient temperature corresponding to the third electrical parameter threshold, then it indicates that the current real-time ambient temperature is greater than or equal to the ambient temperature threshold, that is, the real-time ambient temperature is high.

[0140] The second real-time electrical parameter obtained for this embodiment is at least one of a second real-time voltage, a second real-time resistance and a second real-time current, so the third electrical parameter threshold is correspondingly set to at least one of a third voltage threshold, a third resistance threshold and a third current threshold.

[0141] It can be understood that if the second real-time voltage is obtained, the corresponding third voltage threshold is used to detect the real-time ambient temperature. If the second real-time voltage does not meet the third voltage threshold, that is, the real-time ambient temperature corresponding to the second real-time voltage is higher than or equal to the real-time ambient temperature corresponding to the third voltage threshold, it means that the current real-time ambient temperature is high. If the second real-time voltage meets the third voltage threshold, that is, the real-time ambient temperature corresponding to the second real-time voltage is lower than the real-time ambient temperature corresponding to the third voltage threshold, it means that the current real-time ambient temperature is low.

[0142] If the second real-time resistance is obtained, the corresponding third resistance threshold is used to detect the real-time ambient temperature. If the second real-time resistance does not meet the third resistance threshold, that is, the real-time ambient temperature corresponding to the second real-time resistance is higher than or equal to the real-time ambient temperature corresponding to the third resistance threshold, it means that the current real-time ambient temperature is high. If the second real-time resistance meets the third resistance threshold, that is, the real-time ambient temperature corresponding to the second real-time resistance is lower than the real-time ambient temperature corresponding to the third resistance threshold, it means that the current real-time ambient temperature is low.

[0143] If the second real-time current is obtained, the corresponding third current threshold is used to detect the real-time ambient temperature. If the second real-time current does not meet the third current threshold, that is, the real-time ambient temperature corresponding to the second real-time current is higher than or equal to the real-time ambient temperature corresponding to the third current threshold, it means that the current real-time ambient temperature is high. If the second real-time current meets the third current threshold, that is, the real-time ambient temperature corresponding to the second real-time current is lower than the real-time ambient temperature corresponding to the third current threshold, it means that the current real-time ambient temperature is low.

[0144] Further, when the second temperature sensor is an NTC thermistor, the second real-time electrical parameter is a current parameter, and the third electrical parameter threshold is also a current parameter, if the second real-time current is greater than or equal to the third current threshold, it indicates that the real-time ambient temperature has reached or exceeded the ambient temperature threshold, causing the second real-time current of the NTC thermistor to continuously rise to the third current threshold, or exceed the third current threshold; if the second real-time current is less than the third current threshold, it indicates that the real-time ambient temperature is less than the ambient temperature threshold, and the current real-time ambient temperature is low.

[0145] When the second temperature sensor is an NTC thermistor, the second real-time electrical parameter is a voltage parameter, and the third electrical parameter threshold is also a voltage parameter, if the second real-time voltage is less than or equal to the third voltage threshold, it indicates that the real-time ambient temperature has reached or exceeded the ambient temperature threshold, causing the second real-time voltage output by the NTC thermistor to continuously drop to the third voltage threshold, or be less than the third voltage threshold; if the second real-time voltage is greater than the third voltage threshold, it indicates that the real-time ambient temperature is less than the ambient temperature threshold, and the current real-time ambient temperature is low.

[0146] When the second temperature sensor is an NTC thermistor, the second real-time electrical parameter is a resistance parameter, and the third electrical parameter threshold is also a resistance parameter, if the second real-time resistance is less than or equal to the third resistance threshold, it indicates that the real-time ambient temperature has reached or exceeded the ambient temperature threshold, causing the second real-time resistance of the NTC thermistor to continuously drop to the third resistance threshold, or be less than the third resistance threshold; if the second real-time resistance is greater than the third resistance threshold, it indicates that the real-time ambient temperature is less than the ambient temperature threshold, and the current real-time ambient temperature is low.

[0147] In addition, when the second temperature sensor is a PTC thermistor, the second real-time electrical parameter is a current parameter, and the third electrical parameter threshold is also a current parameter, if the second real-time current is less than or equal to the third current threshold, it indicates that the real-time ambient temperature has reached or exceeded the ambient temperature threshold, causing the second real-time current of the PTC thermistor to continuously drop to the third current threshold, or be less than the third current threshold; if the second real-time current is greater than the third current threshold, it indicates that the real-time ambient temperature is less than the ambient temperature threshold, and the current real-time ambient temperature is low.

[0148] When the second temperature sensor is a PTC thermistor, the second real-time electrical parameter is a voltage parameter, and the third electrical parameter threshold is also a voltage parameter, if the second real-time voltage is greater than or equal to the third voltage threshold, it indicates that the real-time ambient temperature has reached or exceeded the ambient temperature threshold, causing the second real-time voltage output by the PTC thermistor to continuously rise to the third voltage threshold, or exceed the third voltage threshold; if the second real-time voltage is less than the third voltage threshold, it indicates that the real-time ambient temperature is less than the ambient temperature threshold, and the current real-time ambient temperature is low.

[0149] When the second temperature sensor is a PTC thermistor, the second real-time electrical parameter is a resistance parameter, and the third electrical parameter threshold is also a resistance parameter, if the second real-time resistance is greater than or equal to the third resistance threshold, it indicates that the real-time ambient temperature has reached or exceeded the ambient temperature threshold, causing the second real-time resistance of the PTC thermistor to continuously rise to the third resistance threshold, or exceed the third resistance threshold; if the second real-time resistance is less than the third resistance threshold, it indicates that the real-time ambient temperature is less than the ambient temperature threshold, and the current real-time ambient temperature is low.

[0150] Furthermore, when it is judged that the current real-time ambient temperature has reached or exceeded the ambient temperature threshold, it indicates that the heat exchange efficiency between the current target device, the heat dissipation module and the external environment is low. In order to ensure the heat dissipation effect of the target device, it is necessary to control the heat dissipation module to increase its operating power; and when it is judged that the current real-time ambient temperature is lower than the ambient temperature threshold, it indicates that the heat exchange efficiency between the current target device, the heat dissipation module and the external environment is high. Therefore, the heat dissipation module can be controlled to appropriately reduce its operating power, thereby saving the power consumption of the heat dissipation module while ensuring the heat dissipation effect.

[0151] It is worth noting that this embodiment does not limit the sensor type and parameter type of the first temperature sensor and the second temperature sensor to be the same or different. The combination of the sensor type and parameter type of the first temperature sensor and the second temperature sensor can be as follows:

[0152] (1) Both the first temperature sensor and the second temperature sensor are NTC thermistors, and the parameter types of the acquired first real-time electrical parameter and the acquired second real-time electrical parameter are both current parameters.

[0188] As a preferred embodiment, the method further comprises:

[0189] Controlling the operating state of the target device according to the first real-time electrical parameter, a fourth electrical parameter threshold value and a fifth electrical parameter threshold value corresponding to the first temperature sensor;

[0190] Among them, the real-time operating temperature of the target device corresponding to the fourth electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the second electrical parameter threshold, and the real-time operating temperature of the target device corresponding to the fifth electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the fourth electrical parameter threshold; the fourth electrical parameter threshold is at least one of a fourth voltage threshold, a fourth resistance threshold and a fourth current threshold, and the fifth electrical parameter threshold is at least one of a fifth voltage threshold, a fifth resistance threshold and a fifth current threshold.

[0191] It is worth noting that after controlling the heat dissipation module to operate in high-power mode, the target device may still continue to generate heat due to reasons such as dust accumulation on the heat dissipation module affecting the heat dissipation effect, excessive ambient temperature, excessive software running load, etc., and the operating temperature continues to rise. In order to further prevent the target device from burning out, this embodiment additionally sets a fourth electrical parameter threshold and a fifth electrical parameter threshold corresponding to the first temperature sensor, and judges the timing of controlling the operating state of the target device based on the fourth electrical parameter threshold and the fifth electrical parameter threshold. It can be understood that the real-time operating temperature of the target device corresponding to the fourth electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the second electrical parameter threshold, that is, the fourth electrical parameter threshold indicates that the target device is currently at a higher abnormal operating temperature, and the abnormal operating temperature threshold is higher than the abnormal operating temperature threshold corresponding to the second electrical parameter threshold. When the acquired first real-time electrical parameter does not meet the fourth electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time electrical parameter is higher than or equal to the real-time operating temperature of the target device corresponding to the fourth electrical parameter threshold, it indicates that the heat dissipation effect of the current heat dissipation module is insufficient, and the operating state of the target device needs to be adjusted at the same time to reduce its own heat generation; and the real-time operating temperature of the target device corresponding to the fifth electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the fourth electrical parameter threshold, that is, the fifth electrical parameter threshold indicates that the target device has currently reached the limited operating temperature, and its own heat generation needs to be further reduced to avoid burning.

[0192] The first real-time electrical parameter obtained for this embodiment is at least one of the first real-time voltage, the first real-time resistance and the first real-time current, so the fourth electrical parameter threshold is correspondingly set to at least one of the fourth voltage threshold, the fourth resistance threshold and the fourth current threshold, and the fifth electrical parameter threshold is correspondingly set to at least one of the fifth voltage threshold, the fifth resistance threshold and the fifth current threshold.

[0193] It can be understood that if the first real-time voltage is obtained, the corresponding fourth voltage threshold and fifth voltage threshold are used to detect the real-time operating temperature of the target device. If the first real-time voltage does not meet the fourth voltage threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time voltage is higher than or equal to the real-time operating temperature of the target device corresponding to the fourth voltage threshold, then it means that the operating temperature of the current target device has reached a higher abnormal operating temperature threshold, the heat dissipation effect of the heat dissipation module is insufficient, and the heat generation of the target device itself needs to be reduced at the same time; if the first real-time voltage does not meet the fifth voltage threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time voltage is higher than or equal to the real-time operating temperature of the target device corresponding to the fifth voltage threshold, then it means that the operating temperature of the current target device has reached the limited operating temperature threshold, and it cannot continue to operate, and the heat generation of the target device itself needs to be further reduced.

[0194] If the first real-time resistance is obtained, the corresponding fourth resistance threshold and fifth resistance threshold are used to detect the real-time operating temperature of the target device. If the first real-time resistance does not meet the fourth resistance threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time resistance is higher than or equal to the real-time operating temperature of the target device corresponding to the fourth resistance threshold, it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, the heat dissipation effect of the heat dissipation module is insufficient, and the heat generation of the target device itself needs to be reduced at the same time; if the first real-time resistance does not meet the fifth resistance threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time resistance is higher than or equal to the real-time operating temperature of the target device corresponding to the fifth resistance threshold, it means that the current operating temperature of the target device has reached the limited operating temperature threshold and cannot continue to operate, and the heat generation of the target device itself needs to be further reduced.

[0195] If the first real-time current is obtained, the corresponding fourth current threshold and fifth current threshold are used to detect the real-time operating temperature of the target device. If the first real-time current does not meet the fourth current threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time current is higher than or equal to the real-time operating temperature of the target device corresponding to the fourth current threshold, then it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, the heat dissipation effect of the heat dissipation module is insufficient, and the heat generation of the target device itself needs to be reduced at the same time; if the first real-time current does not meet the fifth current threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time current is higher than or equal to the real-time operating temperature of the target device corresponding to the fifth current threshold, then it means that the current operating temperature of the target device has reached the limited operating temperature threshold, and it cannot continue to operate, and the heat generation of the target device itself needs to be further reduced.

At this time, it is necessary to control the target device to reduce its operating power so that the target device reduces its heat generation, and under the joint action of the heat dissipation module, the target device is quickly cooled to the normal operating temperature.

[0205] When the first temperature sensor is an NTC thermistor, and the parameter types of the first real-time electrical parameter and the fourth electrical parameter threshold are both resistances, if the first real-time resistance is less than or equal to the fourth resistance threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold after reaching the abnormal temperature threshold corresponding to the second electrical parameter threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time resistance of the NTC thermistor to continue to drop to the fourth resistance threshold, or be less than the fourth resistance threshold.

[0206] When the first temperature sensor is a PTC thermistor, and the parameter types of the first real-time electrical parameter and the fourth electrical parameter threshold are both current, if the first real-time current is less than or equal to the fourth current threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold after reaching the abnormal temperature threshold corresponding to the second electrical parameter threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time current of the PTC thermistor to continue to drop to the fourth current threshold, or be less than the fourth current threshold. At this time, it is necessary to control the target device to reduce its operating power so that the target device reduces its heat generation, and under the joint action of the heat dissipation module, the target device is quickly cooled to the normal operating temperature.

[0207] When the first temperature sensor is a PTC thermistor, and the parameter types of the first real-time electrical parameter and the fourth electrical parameter threshold are both voltage, if the first real-time voltage is greater than or equal to the fourth voltage threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold after reaching the abnormal temperature threshold corresponding to the second electrical parameter threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time voltage of the PTC thermistor to continue to rise to the fourth voltage threshold, or exceed the fourth voltage threshold. At this time, it is necessary to control the target device to reduce its operating power so that the target device reduces its heat generation, and under the joint action of the heat dissipation module, the target device is quickly cooled to the normal operating temperature.

[0208] When the first temperature sensor is a PTC thermistor, and the parameter types of the first real-time electrical parameter and the fourth electrical parameter threshold are both resistance, if the first real-time resistance is greater than or equal to the fourth resistance threshold, it indicates that the real-time operating temperature of the target device continues to rise to a higher abnormal temperature threshold after reaching the abnormal temperature threshold corresponding to the second electrical parameter threshold, or exceeds the higher abnormal temperature threshold, causing the first real-time resistance of the PTC thermistor to continue to rise to the fourth resistance threshold, or exceed the fourth resistance threshold. At this time, it is necessary to control the target device to reduce its operating power so that the target device reduces its heat generation, and under the joint action of the heat dissipation module, the target device is quickly cooled to the normal operating temperature.

[0209] It is worth noting that when it is detected that the first real-time electrical parameter of the first temperature sensor meets the fourth electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time voltage is lower than the real-time operating temperature of the target device corresponding to the fourth voltage threshold, the initial operating power of the target device before the operating power is reduced is restored to restore the efficient operation of the target device.

[0223] In an optional embodiment, when it is detected that the first real-time electrical parameter of the first temperature sensor meets the fifth electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time electrical parameter is lower than the real-time operating temperature of the target device corresponding to the fifth electrical parameter threshold, the operation of the target device is restored to ensure that the electronic device continues to operate normally. In addition, in order to further ensure the safe operation of the target device, the operation of the target device can also be restored when it is detected that the first real-time electrical parameter of the first temperature sensor meets the first electrical parameter threshold, which is not specifically limited in this embodiment.

[0224] As a preferred solution, the method specifically controls the heat dissipation module to increase or decrease its operating power through the following steps:

[0225] When the heat dissipation module operates in the low power mode, obtaining a first temperature control coefficient corresponding to the first real-time electrical parameter based on a preset temperature control coefficient mapping table;

[0226] According to the temperature difference between the real-time ambient temperature corresponding to the second real-time electrical parameter and the ambient temperature threshold corresponding to the third electrical parameter threshold, obtaining the power adjustment value corresponding to the temperature difference from a preset power adjustment value mapping table;

[0227] According to the maximum operating power of the heat dissipation module, the first temperature control coefficient and the power adjustment value, the expression: P1 = P0 × C1 + P c , determine the first target operating power, and control the operating power of the heat dissipation module to increase or decrease to the first target operating power; wherein P0 represents the maximum operating power, C1 represents the first temperature control coefficient, which is greater than 0 and less than 0.5, P c represents the power adjustment value, P1 represents the first target operating power;

[0228] When the heat dissipation module operates in the high power mode, acquiring a second temperature control coefficient corresponding to the first real-time electrical parameter based on the temperature control coefficient mapping table;

[0229] According to the temperature difference between the real-time ambient temperature corresponding to the second real-time electrical parameter and the ambient temperature threshold corresponding to the third electrical parameter threshold, obtaining the power adjustment value corresponding to the temperature difference from a preset power adjustment value mapping table;

[0230] According to the maximum operating power of the heat dissipation module, the second temperature control coefficient and the power adjustment value, the expression: P2 = P0 × C2 + P c , determine a second target operating power, and control the operating power of the heat dissipation module to increase or decrease to the second target operating power; wherein C2 represents the second temperature control coefficient, which is greater than 0.5 and less than or equal to 1, and P2 represents the second target operating power;

[0231] The temperature control coefficient mapping table records temperature control coefficients corresponding to different first real-time electrical parameters; and the power adjustment value mapping table records power adjustment values ​​corresponding to different temperature differences.

[0232] Specifically, the present embodiment sets a corresponding temperature control coefficient for each first real-time electrical parameter, thereby forming the temperature control coefficient mapping table. It can be understood that when the first real-time electrical parameter does not meet the first electrical parameter threshold, that is, the real-time operating temperature of the target device corresponding to the first real-time electrical parameter is higher than or equal to the real-time operating temperature of the target device corresponding to the first electrical parameter threshold, the temperature control coefficient is greater than 0 and less than 0.5, so as to control the operating power of the heat dissipation module within 1 / 2 of the maximum operating power; and when the first real-time electrical parameter does not meet the second electrical parameter threshold, the temperature control coefficient is greater than 0.5 and less than or equal to 1, so as to control the operating power of the heat dissipation module within a range greater than 1 / 2 of the maximum operating power. In addition, the higher the real-time operating temperature of the target device corresponding to the first real-time electrical parameter, the greater the temperature control coefficient, so as to improve the operating efficiency of the heat dissipation module, and the lower the real-time operating temperature of the target device corresponding to the first real-time electrical parameter, the smaller the temperature control coefficient, so as to reduce the operating efficiency of the heat dissipation module. Exemplarily, assuming that the first temperature sensor is a PTC thermistor, and the parameter type of the first real-time electrical parameter obtained is resistance, if the first real-time resistance is greater than or equal to the first resistance threshold, the corresponding temperature control coefficient is greater than 0 and less than 0.5, and within this range, as the first real-time resistance increases, the temperature control coefficient gradually increases; and if the first real-time resistance is greater than or equal to the second resistance threshold, the corresponding temperature control coefficient is greater than 0.5 and less than or equal to 1, and within this range, as the first real-time resistance increases, the temperature control coefficient gradually increases. Of course, the temperature control coefficient mapping table in this embodiment not only records the temperature control coefficient corresponding to the first real-time resistance under the PTC thermistor, but also records the temperature control coefficients under different types of temperature sensors and different real-time electrical parameters. This is just one example, and this embodiment will not be described in detail here.

[0233] Further, in this embodiment, the temperature difference between the real-time ambient temperature corresponding to the second real-time electrical parameter and the ambient temperature threshold corresponding to the third electrical parameter threshold is the result of subtracting the current real-time ambient temperature from the ambient temperature threshold, so it can be negative, 0 or positive. Since the temperature difference can represent the current heat exchange efficiency, specifically, when the temperature difference is less than 0, it means that the current heat exchange efficiency is high, and when the temperature difference is greater than or equal to 0, it means that the current heat exchange efficiency is low, therefore, in this embodiment, a corresponding power adjustment value is set for each temperature difference, thereby forming the power adjustment value mapping table. It can be understood that the power adjustment value can also be negative, 0 or positive. When the power adjustment value is negative, it means that the operating power of the heat dissipation module needs to be reduced at present. When the power adjustment value is 0, it means that under the temperature control coefficient obtained above, there is no need to further adjust the operating power of the heat dissipation module. When the power adjustment value is positive, it means that the operating power of the heat dissipation module needs to be increased at present. Based on this, when the temperature difference is negative, the heat exchange efficiency is high at this time, so the corresponding power adjustment value is negative, and as the temperature difference gradually decreases, the power adjustment value will gradually decrease. For example, the power adjustment value corresponding to the temperature difference of -3°C is greater than the power adjustment value corresponding to the temperature difference of -5°C, so as to appropriately reduce the operating power of the heat dissipation module when the heat exchange efficiency is high. When the temperature difference is 0, the heat exchange efficiency is moderate at this time. In order to balance the heat dissipation effect and power consumption at the same time, the corresponding power adjustment value is 0, that is, under the temperature control coefficient obtained above, there is no need to further adjust the operating power of the heat dissipation module. When the temperature difference is positive, the heat exchange efficiency is low at this time, so the corresponding power adjustment value is positive, and as the temperature difference gradually increases, the power adjustment value will gradually increase. For example, the power adjustment value corresponding to the temperature difference of 7°C is less than the power adjustment value corresponding to the temperature difference of 15°C, so as to appropriately increase the operating power of the heat dissipation module when the heat exchange efficiency is low.

[0234] It can be understood that, since the mapping relationship between the second real-time electrical parameter and the real-time ambient temperature has been determined, the ambient temperature threshold corresponding to the third electrical parameter threshold can be determined based on the mapping relationship.

[0235] Furthermore, in this embodiment, the expression: P1 = P0 × C1 + P c , determine the first target operating power in low power mode, since the power adjustment value P c The value of can be a negative number or a non-negative number, so it is possible to dynamically adjust the operating power of the heat dissipation module based on the second real-time electrical parameter within a low power range, fully considering the impact of ambient temperature on the heat exchange efficiency, and significantly improving the adjustment accuracy of the operating power of the heat dissipation module.

[0236] By the expression P2 = P0 × C2 + Pc , determine the second target operating power in high power mode, since the power adjustment value P c The value of can be a negative or non-negative number, so it is possible to dynamically adjust the operating power of the heat dissipation module based on the second real-time electrical parameter within a high power range, fully considering the impact of ambient temperature on the heat exchange efficiency, and significantly improving the adjustment accuracy of the operating power of the heat dissipation module.

The temperature detection has high accuracy and no hysteresis. In addition, the real-time electrical parameter of the second temperature sensor is used to determine the real-time ambient temperature to take into account the current heat exchange efficiency, so that the operating power of the heat dissipation module can be adjusted in a timely and accurate manner in combination with the first real-time electrical parameter and the second real-time electrical parameter to avoid the occurrence of overheating of the electronic device.
