Once the battery is fully charged, the output voltage of the voltage regulation module will be maintained at around 12V. When the power consumption of the electronic device increases, the voltage regulation module, as a critical path for all power output from the host, will generate a large amount of heat, causing the electronic device to overheat. This poses a potential risk to the operation of the electronic device, and the heat transferred to the surface of the electronic device also reduces the user experience. Summary of the Invention

It should be noted that the following embodiments can be referenced, borrowed, or combined with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described again.

[0052] This application provides a temperature control system, see [link to relevant documentation]. Figure 1 As shown, the temperature control system 10 includes a power management unit 120 and a temperature control unit 110. The temperature control unit 110 includes a temperature sensing module 111 and a control module 112. The power management unit 120 includes a voltage regulation module 121. The control module 112 is electrically connected to the power management unit 120.

[0053] Optionally, the control module 112 can be electrically connected to the voltage regulation module 121 directly or through other modules in the power management unit 120 to reduce the voltage difference between the output voltage and the input voltage of the control voltage regulation module 121.

[0054] In some embodiments, participate Figure 1 As shown, the power management unit 120 also includes a power control module 122, which is electrically connected to the voltage regulation module 121.

[0055] The control module 112 is electrically connected to the power control module 122. If the temperature value corresponding to the temperature data is higher than the first preset temperature, the control module 112 sends a first control signal to the power control module 122 so that the power control module 122 controls the voltage difference between the output voltage and the input voltage of the voltage regulation module 121 to decrease based on the first control signal.

[0056] In this embodiment, the control module 112 sends a first control signal to the power control module 122 to reduce the voltage difference between the output voltage and the input voltage of the voltage regulation module 121 when the temperature value corresponding to the temperature data is higher than the first preset temperature, so that the voltage difference is within the first voltage difference range.

[0057] In some embodiments, see Figure 1 As shown, the temperature regulation system 10 also includes a central processing unit 130. A control module 112 is electrically connected to the central processing unit 130 and is used to send a second control signal to the central processing unit 130 if the temperature value corresponding to the temperature data is higher than a second preset temperature; the second control signal is used to control the workload of the central processing unit 130 to decrease.

[0058] The process of temperature regulation implemented by the temperature regulation unit in the embodiments of this application is further explained below.

[0059] This application provides a temperature regulation unit, see [link to relevant documentation] Figure 2 As shown, the temperature regulation unit 110 includes a temperature sensing module 111 and a control module 112.

[0060] The temperature sensing module 111 is used to set the voltage regulation module 121 within a first preset range.

[0061] The control module 112 is electrically connected to the temperature sensing module 111. The control module 112 is used to acquire the temperature data of the temperature sensing module 111. If the temperature value corresponding to the temperature data is higher than the first preset temperature, the control module 121 reduces the voltage difference between the output voltage and the input voltage so that the voltage difference is within the first voltage difference range.

[0062] Optionally, the first differential pressure range can be set according to the actual situation, or the first differential pressure range can be 0, so that the output voltage is equal to the input voltage.

[0063] In this embodiment, a temperature sensing module 111 is provided within a first preset range of the voltage regulation module 121. When the temperature value corresponding to the temperature data is higher than the first preset temperature, the control module 112 can control the voltage difference between the output voltage and the input voltage of the voltage regulation module 121 to decrease, so that the voltage difference is within the first voltage difference range. This achieves the technical effect of reducing the operating temperature of the voltage regulation module 121, that is, reducing the operating temperature of the power management unit 120, thereby avoiding the overheating of the electronic device, ensuring the normal operation of the electronic device, and also reducing the surface temperature of the electronic device, improving the user experience.

[0064] Optionally, the temperature sensing module 111 includes at least one temperature sensor. If the temperature sensing module 111 is a single temperature sensor, the temperature data from the temperature sensor is used as the corresponding temperature value. If the temperature sensing module 111 includes multiple temperature sensors, the temperature value corresponding to the temperature data can be the average temperature of the temperature data from all temperature sensors or the maximum temperature value among the temperature data from all temperature sensors.

[0065] Optionally, the distance between the temperature sensing module 111 and the voltage regulation module 121 is within a first preset range. The first preset range can be set according to the actual situation, for example, the first preset range is 0.5mm-5mm, including 0.5mm and 5mm.

[0066] In some embodiments, the control module 112 is further configured to control the workload of the central processing unit 130 to decrease if the temperature value corresponding to the temperature data is higher than the second preset temperature, so as to reduce the operating current of the central processing unit 130; the second preset temperature is higher than the first preset temperature.

[0067] Optionally, the first preset temperature can be 70°C and the second preset temperature can be 90°C.

[0068] The embodiments of this application can solve the problem of reducing the temperature of the power management unit 120 by changing the output voltage while ensuring that the performance of the electronic device is not reduced in high-performance mode. Furthermore, if the temperature continues to rise and reaches the usage limit, the control module 112 can issue an instruction to reduce the performance of the central processing unit 130, thereby changing the total current and achieving the purpose of reducing the temperature of the power management unit 120.

[0069] Research revealed that during the operation of the power management unit 120, the voltage regulation module 121, consisting of two switching submodules that alternately turn on and off (i.e., switching operation), experiences wear and tear on the switching devices due to repeated switching. Thermal imaging analysis showed that the voltage regulation module 121 is one of the common heat sources on the motherboard. Furthermore, the voltage regulation module 121 is often located far from the active cooling area of ​​the fan, making it prone to heat accumulation and increasing temperature.

[0070] Based on the above, see Figure 3 As shown, the voltage regulation module 121 includes a first switch submodule 1211 and a second switch submodule 1212. The first end of the first switch submodule 1211 and the first end of the second switch submodule 1212 are electrically connected to a first voltage terminal and a second voltage terminal, respectively. The second end of the first switch submodule 1211 and the second end of the second switch submodule 1212 are electrically connected and electrically connected to a third voltage terminal. The voltage at the first voltage terminal is the input voltage, and the voltage at the third voltage terminal is the output voltage.

[0071] The control module 112 is specifically used to control the first switch submodule 1211 to turn on and the second switch submodule 1212 to turn off if the temperature value corresponding to the temperature data is higher than the first preset temperature, so as to reduce the voltage difference between the output voltage and the input voltage.

[0072] In some embodiments, the control module 112 is specifically used to control the number of working cores of the central processing unit 130 to be reduced to a set number, so as to reduce the workload. For example, from 4 cores to 1 core.

[0073] Optionally, see Figure 3 As shown, the first switch submodule 1211 includes a switch device Q1, the second switch submodule 1212 includes a switch device Q2, the input voltage of the first voltage terminal is Vin, the second voltage terminal is grounded, and the output voltage of the third voltage terminal is Vout. Figure 3 As shown, Charger represents the power control module 122, EC represents the control module 112, CPU represents the central processing unit 130, Thermal Sensor represents the temperature sensing module 111, I2C Bus Control represents the first control signal, and Prochot Signal represents the second control signal. EC (embedded controller) is an embedded controller, a chip, which can be software-controlled such as a keyboard; Charger is the power controller circuit, and the power controller circuit and voltage regulation module 121 together form the power management unit 120. Switching devices Q1 and Q2 can be MOSFETs.

[0074] Optionally, the Charger is the main interface for all power inputs and outputs on the laptop motherboard, and it also has the function of charging the battery. Due to the high integration of the components, the temperature on the motherboard is high when the current is too large.

[0075] See Figure 3As shown, switching devices Q1 and Q2 work together under normal conditions. A typical SwitchPower outputs a voltage of around 12. The thermal sensor is placed around switching devices Q1 and Q2, for example, the thermal sensor is placed within the first preset range of switching device Q1.

[0076] The thermal sensor detects the temperatures of switching devices Q1 and Q2. When the temperature is too high, Q1 is initially turned on while Q2 is turned off. At this time, the input voltage Vin equals the output voltage Vout. Switch Q2 does not generate any temperature at this point, and the normally open operation of Q1 causes its temperature to decrease. If the temperature continues to rise, a Prochot Signal is sent via the EC (Electronic Control Unit) to degrade CPU performance. This reduces the current flowing through Q1, causing the temperatures of both Q1 and Q2 to decrease.

[0077] This application aims to address the issue of reducing Charger temperature in high-performance mode of electronic devices by altering the output voltage without compromising performance. Furthermore, if the temperature continues to rise and reaches its operating limit, the EC (Engineer Control Center) can send a command to the CPU to reduce CPU performance, thereby altering the total current and lowering the Charger temperature. On one hand, this application can automatically change the output voltage Vint from the Charger to the motherboard, reducing the voltage drop and thus lowering the Charger's operating temperature. On the other hand, when the Charger temperature exceeds a certain level, this application can send a Prochot Signal to the CPU to reduce CPU performance, thereby lowering the Charger temperature and achieving forced Charger cooling.

[0078] This application embodiment allows the EC to obtain the Charger's operating temperature via a temperature sensor placed around the Charger. If the operating temperature is too high, the Charger regulating switch Q2 is turned off, and switch Q1 is turned on, causing a change in the output voltage and reducing the voltage difference, thereby achieving the technical effect of lowering the Charger's operating temperature. The temperature reduction control in this application embodiment is dynamically adjusted, and the EC's control function can be turned on and off by installing the Setup software.

[0079] The embodiments of this application feature the combination of key components and software and hardware technologies, requiring changes to the circuit connection to the EC during the design phase, and the internal program to control the output voltage.

[0080] Optionally, see Figure 3As shown, the voltage regulation module 121 also includes an inductor. The first end of the inductor is electrically connected to the second end of both the first switch submodule 1211 and the second end of both the second switch submodule 1212. The second end of the inductor is electrically connected to the third voltage terminal. The power control module 122 is electrically connected to the control terminal of both the first switch submodule 1211 and the control terminal of both the second switch submodule 1212.

[0081] Optionally, the first terminals of switching devices Q1 and Q2 serve as the first terminals of the first switching submodule 1211 and the second switching submodule 1212, respectively; the second terminals of switching devices Q1 and Q2 serve as the second terminals of the first switching submodule 1211 and the second switching submodule 1212, respectively. The control terminals of switching devices Q1 and Q2 serve as the control terminals of the first switching submodule 1211 and the second switching submodule 1212, respectively.

[0082] It is understandable that the control module 112 can be directly electrically connected to the control terminals of both the first switch submodule 1211 and the second switch submodule 1212, and directly control the on and off states of the first switch submodule 1211 and the second switch submodule 1212.

[0083] Research has revealed that previous circuit designs did not detect the temperature of the Charger, often overlooking the disadvantage of excessively high temperatures. By adding a temperature sensor to this heat source, when the temperature is too high, a Prochot Signal can be sent to the CPU via the EC, causing the CPU to reduce performance and the overall power consumption to decrease, thereby cooling the Charger and forming a closed-loop temperature control system for the Charger.

[0084] This embodiment of the application uses a temperature sensor placed near the Charger heat source to monitor the Charger's temperature in real time. When the temperature is too high, the switching device Q1 is turned on directly, eliminating the various losses of the alternating switch power in its output circuit, reducing the pathway for heat generation in the Charger, and thus lowering the temperature. When the Charger temperature drops to a reasonable value, it will switch back to normal voltage.

[0085] Based on the same inventive concept, this application provides a temperature regulation method, which includes: acquiring temperature data from a temperature sensing module 111; if the temperature value corresponding to the temperature data is higher than a first preset temperature, then controlling the voltage difference between the output voltage and the input voltage of a voltage regulation module 121 to reduce the voltage difference within a first voltage difference range.

[0086] In some embodiments, after acquiring the temperature data from the temperature sensing module 111, the method further includes:

[0087] If the temperature value corresponding to the temperature data is higher than the second preset temperature, the workload of the central processing unit 130 is reduced so as to reduce the operating current of the central processing unit 130; the second preset temperature is higher than the first preset temperature.

[0088] As an example, this application provides a temperature regulation method applied to the temperature regulation unit of this application embodiment. See [link to relevant documentation]. Figure 4 As shown, the temperature regulation method includes steps S401 to S403.

[0089] 401. Obtain temperature data from temperature sensing module 111.

[0090] The temperature regulation method in this embodiment is executed by the control module 112.

[0091] Optionally, the control module 112 acquires the temperature data from the temperature sensing module 111.

[0092] 402. If the temperature value corresponding to the temperature data is higher than the first preset temperature, the voltage difference between the output voltage and the input voltage of the control voltage adjustment module 121 is reduced so that the voltage difference is within the first voltage difference range.

[0093] Optionally, the control module 112 determines whether the temperature value corresponding to the temperature data is higher than the first preset temperature. If the temperature value corresponding to the temperature data is higher than the first preset temperature, the control module 121 reduces the voltage difference between the output voltage and the input voltage so that the voltage difference is within the first voltage difference range.

[0094] Optionally, reducing the voltage difference between the output voltage and the input voltage of the control voltage regulation module 121 includes controlling the first switch submodule 1211 to be turned on and the second switch submodule 1212 to be turned off, so as to reduce the voltage difference between the output voltage and the input voltage.

[0095] 403. If the temperature value corresponding to the temperature data is higher than the second preset temperature, the workload of the central processing unit 130 is reduced so as to reduce the operating current of the central processing unit 130; the second preset temperature is higher than the first preset temperature.

[0096] Optionally, the control module 112 determines whether the temperature value corresponding to the temperature data is higher than the second preset temperature. If the temperature value corresponding to the temperature data is higher than the second preset temperature, the control module 130 reduces the workload of the central processing unit 130 so as to reduce the operating current of the central processing unit 130.

[0097] Optionally, reducing the workload of the central processing unit 130 includes reducing the number of working cores of the central processing unit 130 to a set number. For example, reducing the number of cores from 4 to 1.

[0098] As an example, combined Figure 3 The temperature regulation system shown in this application, and the temperature regulation method of this embodiment, include:

[0099] Setting 1: The first preset temperature for switching between Mode 1 and Mode 2 when the Charger temperature is too high, for example, set to 70 degrees.

[0100] Setting 2: When the temperature continues to rise after changing to mode 1 and reaching the second preset temperature, the EC will send a Prochot Signal to the CPU, causing the CPU's Prochot to reduce the CPU load and reduce the current to lower the temperature.

[0101] Mode 1: Switching devices Q1 and Q2 alternately turn on and off, operating in a switching power supply state.

[0102] Mode 2: Switch Q1 is normally open. In this mode, the heat generated by switch Q1 is caused by its internal equivalent resistance, and switch Q2 is disconnected.

[0103] Based on the above, the temperature adjustment method of this application includes steps one to six.

[0104] Step 1: Detect the temperature and determine the temperature value, then proceed to Step 2.

[0105] Step 2: Determine if the temperature value is greater than the design value of 1. If yes, proceed to Step 3; otherwise, proceed to Step 4.

[0106] Step 3: The EC sets the Charger data as the first control signal, switches to mode 2 based on the first control signal, that is, the switching device Q1 is always on and the switching device Q2 is off, and then continues to detect the temperature and executes step 5.

[0107] Step 4: Determine if the current mode is mode 2. If yes, switch to mode 1. If no, proceed to step 1.

[0108] Step 5: Determine if the temperature value is greater than the design value of 2. If yes, proceed to step 6; otherwise, proceed to step 1.

[0109] Step 6: The EC sends a Prochot Signal to the CPU as a second control signal, causing the CPU to reduce its performance.

[0110] Based on the same inventive concept, this application provides a temperature regulating device, see [link to relevant documentation]. Figure 5 As shown, the temperature regulating device 50 includes an acquisition module 510 and an regulating module 520.

[0111] The acquisition module 510 is used to acquire temperature data from the temperature sensing module 111.

[0112] The adjustment module 520 is used to reduce the voltage difference between the output voltage and the input voltage of the voltage adjustment module 121 if the temperature value corresponding to the temperature data is higher than the first preset temperature, so that the voltage difference is within the first voltage difference range.

[0113] Optionally, the adjustment module 520 is used to send a first control signal to the power control module 122 if the temperature value corresponding to the temperature data is higher than the first preset temperature, so that the power control module 122 controls the voltage difference between the output voltage and the input voltage of the voltage adjustment module 121 to decrease based on the first control signal.
