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.

[0058] In the description of this application, it should be noted that, unless otherwise defined, all technical and scientific terms used in the present invention have the same meaning as those commonly understood by those skilled in the art. 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.

[0059] See also Figure 1According 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:

[0060] Step S1, obtaining real-time electrical parameters of the temperature sensor;

[0061] Step S2, adjusting the operating power of the heat dissipation module according to the real-time electrical parameter and a preset first electrical parameter threshold, so that the heat dissipation module dissipates heat for the target device based on the adjusted operating power;

[0062] Among them, the real-time electrical parameters of the temperature sensor have a mapping relationship with the real-time operating temperature of the target device; the temperature sensor is arranged on the surface of the target device, or the temperature sensor is embedded in the circuit board or carrier board on which the target device is assembled.

[0063] 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, resulting in changes in the output electrical signal, such as changes in voltage, current, resistance, etc. Therefore, this embodiment characterizes the real-time operating temperature of the target device currently being detected by acquiring the real-time electrical parameters of the 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 value decreases as the temperature increases, and for PTC thermistors, their resistance value increases as the temperature increases. Therefore, different real-time electrical parameters of the temperature sensor correspond to different real-time operating temperatures of the target device, that is, the real-time electrical parameters of the temperature sensor and the real-time operating temperature of the target device have a one-to-one mapping relationship. Based on this, this embodiment pre-sets the first electrical parameter threshold corresponding to the temperature sensor. 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. In order to be able to take heat dissipation and cooling measures in a timely and accurate manner, the present embodiment needs to determine the control timing of the heat dissipation module based on the real-time electrical parameters of the temperature sensor and the preset first electrical parameter threshold. When the target device exceeds the normal operating temperature, it is necessary to adjust the operating power of the heat dissipation module based on the acquired real-time electrical parameters, so as to be able to perform differentiated heat dissipation for different operating conditions of the target device, effectively avoiding the occurrence of overheating of the target device.

[0064] In addition, the 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 real-time electrical parameters, which significantly improves the detection accuracy and real-time performance; the 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 traditional temperature detection elements, the method of embedding in the circuit board or carrier board can make the distance between the temperature sensor and the target device closer, thereby improving the detection accuracy and real-time performance. At the same time, the 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.

[0065] 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 real-time electrical parameters is different, and thus the corresponding first electrical parameter threshold is also different. Therefore, this embodiment does not make specific limitations on the first electrical parameter threshold.

[0066] As a preferred solution, the real-time electrical parameter is at least one of real-time voltage, real-time resistance and 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.

[0067] It is worth noting that this embodiment can characterize the real-time operating temperature of the target device by obtaining at least one of the real-time voltage, real-time resistance and 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 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 real-time voltage does not meet the first voltage threshold (when the temperature sensor is an NTC thermistor, the real-time electrical parameter is the real-time voltage, the first electrical parameter threshold is the first voltage threshold, and the real-time electrical parameter is less than or equal to the first electrical parameter threshold; when the temperature sensor is a PTC thermistor, the real-time electrical parameter is the real-time voltage, the first electrical parameter threshold is the first voltage threshold, and the real-time electrical parameter is greater than or equal to the first electrical parameter threshold), it means that the current operating temperature of the target device has reached the abnormal operating temperature threshold, is in an abnormal temperature state, and needs to be cooled; if the 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 real-time resistance does not meet the first resistance threshold (when the temperature sensor is an NTC thermistor, the real-time electrical parameter is the real-time resistance, the first electrical parameter threshold is the first resistance threshold, and the real-time electrical parameter is less than or equal to the first When the real-time electrical parameter meets the electrical parameter threshold; when the temperature sensor is a PTC thermistor, the real-time electrical parameter is a real-time resistance, the first electrical parameter threshold is a first resistance threshold, and the real-time electrical parameter is greater than or equal to the first electrical parameter threshold), it indicates 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 dissipated; if the real-time current is obtained (when the temperature sensor is an NTC thermistor, the real-time electrical parameter is the real-time current, the first electrical parameter threshold is the first current threshold, and the real-time electrical parameter is greater than or equal to the first electrical parameter threshold; when the temperature sensor is a PTC thermistor, the real-time electrical parameter is the real-time current, the first electrical parameter threshold is the first current threshold, and the real-time electrical parameter is less than or equal to the first electrical parameter threshold), the corresponding first current threshold is used to detect the real-time operating temperature of the target device. If the real-time current does not meet the first current threshold, it indicates 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 dissipated.

[0068] As a preferred solution, the operating power of the heat dissipation module is adjusted according to the real-time electrical parameter and the preset first electrical parameter threshold, specifically including:

[0069] When the temperature sensor is an NTC thermistor, the real-time electrical parameter is a real-time current, the first electrical parameter threshold is a first current threshold, and the real-time electrical parameter is greater than or equal to the first electrical parameter threshold, adjusting the operating power of the heat dissipation module according to the real-time electrical parameter;

[0070] When the temperature sensor is an NTC thermistor, the real-time electrical parameter is a real-time voltage, the first electrical parameter threshold is a first voltage threshold, and the real-time electrical parameter is less than or equal to the first electrical parameter threshold, adjusting the operating power of the heat dissipation module according to the real-time electrical parameter;

[0071] When the temperature sensor is an NTC thermistor, the real-time electrical parameter is a real-time resistance, the first electrical parameter threshold is a first resistance threshold, and the real-time electrical parameter is less than or equal to the first electrical parameter threshold, adjusting the operating power of the heat dissipation module according to the real-time electrical parameter;

[0072] When the temperature sensor is a PTC thermistor, the real-time electrical parameter is a real-time current, the first electrical parameter threshold is a first current threshold, and the real-time electrical parameter is less than or equal to the first electrical parameter threshold, the operating power of the heat dissipation module is adjusted according to the real-time electrical parameter;

[0073] When the temperature sensor is a PTC thermistor, the real-time electrical parameter is a real-time voltage, the first electrical parameter threshold is a first voltage threshold, and the real-time electrical parameter is greater than or equal to the first electrical parameter threshold, the operating power of the heat dissipation module is adjusted according to the real-time electrical parameter;

[0074] When the temperature sensor is a PTC thermistor, the real-time electrical parameter is a real-time resistance, the first electrical parameter threshold is a first resistance threshold, and the real-time electrical parameter is greater than or equal to the first electrical parameter threshold, the operating power of the heat dissipation module is adjusted according to the real-time electrical parameter.

[0075] 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.

[0076] Therefore, when the temperature sensor is an NTC thermistor, and the parameter types of the real-time electrical parameter and the first electrical parameter threshold are both current, if the 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 real-time current of the NTC thermistor to continue to rise to the first current threshold, or exceed the first current threshold. At this time, it is necessary to enhance the heat dissipation efficiency of the heat dissipation module so that the target device can be quickly cooled to the normal operating temperature. Therefore, this embodiment adjusts the operating power of the heat dissipation module according to the real-time current obtained.

[0077] When the temperature sensor is an NTC thermistor, and the parameter types of the real-time electrical parameter and the first electrical parameter threshold are both voltage, if the 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 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. At this time, it is necessary to enhance the heat dissipation efficiency of the heat dissipation module so that the target device can be quickly cooled to the normal operating temperature. Therefore, this embodiment adjusts the operating power of the heat dissipation module according to the obtained real-time current.

[0078] When the temperature sensor is an NTC thermistor, and the parameter types of the real-time electrical parameter and the first electrical parameter threshold are both resistance, if the 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 real-time resistance of the NTC thermistor to continue to drop to the first resistance threshold, or be less than the first resistance threshold. At this time, it is necessary to enhance the heat dissipation efficiency of the heat dissipation module so that the target device can be quickly cooled to the normal operating temperature. Therefore, this embodiment adjusts the operating power of the heat dissipation module according to the obtained real-time resistance.

[0079] 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 increase in temperature, while the current flowing through the NTC thermistor will decrease with the increase in temperature.

[0080] Therefore, when the temperature sensor is a PTC thermistor, and the parameter types of the real-time electrical parameter and the first electrical parameter threshold are both current, if the 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 real-time current of the PTC thermistor to continue to drop to the first current threshold, or be less than the first current threshold. At this time, it is necessary to enhance the heat dissipation efficiency of the heat dissipation module so that the target device can be quickly cooled to the normal operating temperature. Therefore, this embodiment adjusts the operating power of the heat dissipation module according to the real-time current obtained.

[0081] When the temperature sensor is a PTC thermistor, and the parameter types of the real-time electrical parameter and the first electrical parameter threshold are both voltage, if the 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 real-time voltage output by the PTC thermistor to continue to rise to the first voltage threshold, or exceed the first voltage threshold. At this time, it is necessary to enhance the heat dissipation efficiency of the heat dissipation module so that the target device can be quickly cooled to the normal operating temperature. Therefore, this embodiment adjusts the operating power of the heat dissipation module according to the real-time current obtained.

[0082] When the temperature sensor is a PTC thermistor, and the parameter types of the real-time electrical parameter and the first electrical parameter threshold are both resistance, if the 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 real-time resistance of the PTC thermistor to continue to rise to the first resistance threshold, or exceed the first resistance threshold. At this time, it is necessary to enhance the heat dissipation efficiency of the heat dissipation module so that the target device can be quickly cooled to the normal operating temperature. Therefore, this embodiment adjusts the operating power of the heat dissipation module according to the obtained real-time resistance.

[0083] It is worth noting that when it is detected that the real-time electrical parameter of the temperature sensor meets 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.

[0084] As a preferred embodiment, the method further comprises:

[0085] Controlling the operating state of the target device according to the real-time electrical parameter, the preset second electrical parameter threshold and the third electrical parameter threshold;

[0086] 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 real-time operating temperature of the target device corresponding to the third electrical parameter threshold is greater than the real-time operating temperature of the target device corresponding to the second electrical parameter threshold;

[0087] The second electrical parameter threshold is at least one of a second voltage threshold, a second resistance threshold, and a second current threshold; the third electrical parameter threshold is at least one of a third voltage threshold, a third resistance threshold, and a third current threshold.

[0088] It is worth noting that after adjusting the operating power of the heat dissipation module, the target device may continue to heat up due to reasons such as dust accumulation on the heat dissipation module affecting the heat dissipation effect, too high ambient temperature, too large software running load, etc., and the operating temperature continues to rise. In order to further avoid the target device from burning out, the second electrical parameter threshold and the third electrical parameter threshold are additionally set in this embodiment, and the control timing of the operating state of the target device is judged based on these two electrical parameter thresholds. 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 real-time electrical parameter obtained does not meet the second electrical parameter threshold, it means that the current heat dissipation module can no longer effectively cool down, and the operating state of the target device needs to be adjusted to reduce its own heat generation; and the real-time operating temperature of the target device corresponding to the third 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 third electrical parameter threshold indicates that the target device has currently reached a limited operating temperature and needs to further reduce its own heat generation to avoid burning out.

[0089] The real-time electrical parameter obtained for this embodiment is at least one of real-time voltage, real-time resistance and real-time current, so the second electrical parameter threshold is correspondingly set to at least one of the second voltage threshold, the second resistance threshold and the second current threshold, and the third electrical parameter threshold is also correspondingly set to at least one of the third voltage threshold, the third resistance threshold and the third current threshold.

[0090] It can be understood that if the real-time voltage is obtained, the corresponding second voltage threshold and third voltage threshold are used to detect the real-time operating temperature of the target device. If the real-time voltage does not meet the second voltage threshold, it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, and the heat dissipation module can no longer effectively dissipate the heat for the target device, and the heat generation of the target device itself needs to be reduced; if the real-time voltage does not meet the third voltage threshold, it means that the current operating temperature of the target device has reached the specified operating temperature threshold and cannot continue to operate, and the heat generation of the target device itself needs to be further reduced.

[0091] If the real-time resistance is obtained, the corresponding second resistance threshold and third resistance threshold are used to detect the real-time operating temperature of the target device. If the real-time resistance does not meet 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 module can no longer effectively dissipate the heat for the target device, and the heat generation of the target device itself needs to be reduced; if the real-time resistance does not meet the third 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.

[0092] If the real-time current is obtained, the corresponding second current threshold and third current threshold are used to detect the real-time operating temperature of the target device. If the real-time current does not meet the second current threshold, it means that the current operating temperature of the target device has reached a higher abnormal operating temperature threshold, and the heat dissipation module can no longer effectively dissipate the heat for the target device, and the heat generation of the target device itself needs to be reduced; if the real-time current does not meet the third current 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.

[0103] When the temperature sensor is a PTC thermistor, and the parameter types of the real-time electrical parameter and the second electrical parameter threshold are both current, if the 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 after reaching the abnormal temperature threshold corresponding to the first electrical parameter threshold, or exceeds the higher abnormal temperature threshold, causing the real-time current of the PTC thermistor to continue to decrease to the second current threshold, or be less than the second 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.

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.

[0106] It is worth noting that when it is detected that the real-time electrical parameter of the temperature sensor meets the second electrical parameter threshold, the initial operating power of the target device before reducing the operating power is restored to restore the efficient operation of the target device.

[0121] As a preferred solution, the adjusting the operating power of the heat dissipation module according to the real-time electrical parameters specifically includes:

[0122] When the temperature sensor is an NTC thermistor and the real-time electrical parameter is a real-time current, the target operating power of the heat dissipation module is determined by the following expression: P=P0×(A1 / I0), and the operating power of the heat dissipation module is controlled to be adjusted to the target operating power;

[0123] When the temperature sensor is an NTC thermistor and the real-time electrical parameter is a real-time voltage, the target operating power of the heat dissipation module is determined by the following expression: P=P0×(U0 / A1), and the operating power of the heat dissipation module is controlled to be adjusted to the target operating power;

[0125] When the temperature sensor is a PTC thermistor and the real-time electrical parameter is a real-time current, the target operating power of the heat dissipation module is determined by the following expression: P=P0×(I0 / A1), and the operating power of the heat dissipation module is controlled to be adjusted to the target operating power;

[0126] When the temperature sensor is a PTC thermistor and the real-time electrical parameter is a real-time voltage, the target operating power of the heat dissipation module is determined by the following expression: P=P0×(A1 / U0), and the operating power of the heat dissipation module is controlled to be adjusted to the target operating power;

[0127] When the temperature sensor is a PTC thermistor and the real-time electrical parameter is a real-time resistance, the target operating power of the heat dissipation module is determined by the following expression: P=P0×(A1 / R0), and the operating power of the heat dissipation module is controlled to be adjusted to the target operating power;

[0128] Among them, P represents the target operating power, P0 represents the maximum operating power of the heat dissipation module, A1 represents the real-time electrical parameter, I0 represents the real-time current value of the temperature sensor corresponding to the heat dissipation module when it is running at full power, U0 represents the real-time voltage value of the temperature sensor corresponding to the heat dissipation module when it is running at full power, and R0 represents the real-time resistance value of the temperature sensor corresponding to the heat dissipation module when it is running at full power.

[0129] It is worth noting that when the temperature of the NTC thermistor increases, its resistance and output voltage will decrease as the temperature increases, while the current flowing through the NTC thermistor will increase as the temperature increases. Therefore, in this embodiment, when the temperature sensor is an NTC thermistor and the real-time electrical parameter is the real-time current, based on the maximum operating power of the heat dissipation module and its current when it is running at full power, the target operating power of the heat dissipation module is determined by the formula P=P0×(A1 / I0) when the real-time current is greater than or equal to the first current threshold. It can be understood that as the real-time operating temperature of the target device continues to rise, the power adjustment coefficient: (A1 / I0) will also continue to rise, thereby achieving the maximum operating power of the heat dissipation module. The operating power of the heat dissipation module is dynamically adjusted according to the real-time operating temperature of the target device, and the operating power of the heat dissipation module can be increased as the real-time operating temperature of the target device increases, ensuring the reliability of heat dissipation.

[0130] In this embodiment, when the temperature sensor is an NTC thermistor and the real-time electrical parameter is the real-time voltage, based on the maximum operating power of the heat dissipation module and its voltage when operating at full power, the target operating power of the heat dissipation module when the real-time voltage is less than or equal to the first voltage threshold is determined by the formula P=P0×(U0 / A1). It can be understood that as the real-time operating temperature of the target device continues to rise, although the real-time voltage output by the temperature sensor will continue to decrease, the power adjustment coefficient: (U0 / A1) will continue to increase as the real-time voltage decreases, thereby achieving dynamic adjustment of the operating power of the heat dissipation module according to the real-time operating temperature of the target device within the maximum operating power of the heat dissipation module, and being able to increase the operating power of the heat dissipation module as the real-time operating temperature of the target device increases, thereby ensuring the reliability of heat dissipation.

[0131] In this embodiment, when the temperature sensor is an NTC thermistor and the real-time electrical parameter is the real-time resistance, based on the maximum operating power of the heat dissipation module and its resistance when operating at full power, the target operating power of the heat dissipation module when the real-time resistance is less than or equal to the first resistance threshold is determined by the formula P=P0×(R0 / A1). It can be understood that as the real-time operating temperature of the target device continues to rise, although the real-time resistance of the temperature sensor will continue to decrease, the power adjustment coefficient: (R0 / A1) will continue to increase as the real-time resistance decreases, thereby achieving dynamic adjustment of the operating power of the heat dissipation module according to the real-time operating temperature of the target device within the maximum operating power of the heat dissipation module, and being able to increase the operating power of the heat dissipation module as the real-time operating temperature of the target device increases, thereby ensuring the reliability of heat dissipation.

[0132] In addition, when the temperature of the detection object of the PTC thermistor increases, its resistance and output voltage will increase with the increase of temperature, while the current flowing through the PTC thermistor will decrease with the increase of temperature. Therefore, in this embodiment, when the temperature sensor is a PTC thermistor and the real-time electrical parameter is the real-time current, based on the maximum operating power of the heat dissipation module and its current when it is running at full power, the formula P=P0×(I0 / A1) is used to determine the target operating power of the heat dissipation module when the real-time current is less than or equal to the first current threshold. It can be understood that as the real-time operating temperature of the target device continues to rise, although the real-time current flowing through the temperature sensor continues to decrease, the power adjustment coefficient: (I0 / A1) will continue to increase as the real-time current decreases, thereby realizing the dynamic adjustment of the operating power of the heat dissipation module according to the real-time operating temperature of the target device within the maximum operating power of the heat dissipation module, and being able to increase the operating power of the heat dissipation module as the real-time operating temperature of the target device increases, thereby ensuring the reliability of heat dissipation.

[0133] In this embodiment, when the temperature sensor is a PTC thermistor and the real-time electrical parameter is the real-time voltage, based on the maximum operating power of the heat dissipation module and its voltage when operating at full power, the target operating power of the heat dissipation module when the real-time voltage is greater than or equal to the first voltage threshold is determined by the formula P=P0×(A1 / U0). It can be understood that as the real-time operating temperature of the target device continues to rise, the power adjustment coefficient: (A1 / U0) will also continue to rise accordingly, thereby achieving dynamic adjustment of the operating power of the heat dissipation module according to the real-time operating temperature of the target device within the maximum operating power of the heat dissipation module, and being able to increase the operating power of the heat dissipation module as the real-time operating temperature of the target device increases, thereby ensuring the reliability of heat dissipation.

[0134] In this embodiment, when the temperature sensor is a PTC thermistor and the real-time electrical parameter is the real-time resistance, based on the maximum operating power of the heat dissipation module and its resistance when operating at full power, the target operating power of the heat dissipation module when the real-time resistance is greater than or equal to the first resistance threshold is determined by the formula P=P0×(A1 / R0). It can be understood that as the real-time operating temperature of the target device continues to rise, the power adjustment coefficient: (A1 / R0) will also continue to rise accordingly, thereby achieving dynamic adjustment of the operating power of the heat dissipation module according to the real-time operating temperature of the target device within the maximum operating power of the heat dissipation module, and being able to increase the operating power of the heat dissipation module as the real-time operating temperature of the target device increases, thereby ensuring the reliability of heat dissipation.
