[0045] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0046] In practical applications, a thermoelectric cooler (TEC) can be installed on the outside of a mobile terminal such as a laptop computer to dissipate heat. However, since the TEC is not connected to a fan, its heat dissipation relies on the keyboard, resulting in low efficiency of the TEC and a very hot keyboard. If the power of the TEC is insufficient, it is difficult to dissipate heat from the mobile terminal.

[0047] In an embodiment of the present invention, by controlling the temperature of the metal casing of a mobile terminal and the contact position with the user (such as the C-side) without increasing the volume and power consumption of a mobile terminal such as a laptop computer, the system can be kept cool in summer and hot in winter without increasing the size of the power adapter.

[0048] Take a laptop computer as an example, Figure 1 The C-side of the laptop is made of metal and has good thermal conductivity. One side of the TEC cooling sheet is directly attached to the lower part of the C-side of the laptop. Figure 1 The metal plate on the right side of the middle keyboard and below the palm rest, the other side of the TEC cooling sheet reuses the heat pipe of the CPU or graphics card chip cooling fan (the heat pipe is a highly thermally conductive material that can transfer heat throughout the laptop). The heat at the TEC location can be dissipated through the fan, and the TEC location is the cold side, and the heat from the CPU and graphics card can also be transferred to the TEC location through the heat pipe, thereby helping to cool the CPU and graphics card.

[0049] Moreover, a first temperature sensor can be set on the C-side of the laptop to collect the temperature of the C-side, and a second temperature sensor can be set at the camera position above the laptop screen to collect the ambient temperature as accurately as possible.

[0050] Furthermore, the TEC's power conduction and cooling / heating options are controlled by an embedded controller (EC), which can adjust the C-surface temperature based on ambient temperature and user preferences. Embedded controllers are used in laptop designs with intelligent power-saving features. They are responsible for managing the laptop's built-in keyboard, touchpad, and battery intelligent charge and discharge, as well as temperature monitoring.

[0051] At the software level, corresponding programs can be deployed in laptops, and users can adjust the C-side temperature. Most users will not set these parameters. This data can also be obtained based on surveys. Assume that the software defaults to 22 degrees in summer and 35 degrees in winter to ensure a good user experience.

[0052] For TEC, the specific control strategy can be as follows:

[0053] 1. When the power is turned on, by default, the control program reads the current date and time, obtains the C-side temperature that needs to be controlled, and transmits the current temperature value that needs to be controlled to the EC of the laptop.

[0054] 2. EC can read the ambient temperature and the temperature of the laptop's C-side to determine whether the C-side needs to be heated or cooled. When cooling is required (the same applies to heating), EC reads the power consumed by the laptop and uses the maximum power of the power adapter minus the power consumed by the laptop to drive TEC to work so that the C-side temperature reaches the set temperature.

[0055] Since it is usually set according to the maximum power of the laptop, and the laptop will not run at full power most of the time, the remaining power can be used by TEC as the maximum adjustable power to control the temperature of the C-side, thereby making maximum use of the existing conditions to achieve the above functions without changing the total power of the power adapter or the size of the adapter. The power that was not originally used by the laptop is used for temperature regulation, which does not increase the weight of the adapter of the portable notebook.

[0056] 3. The temperature control software on the laptop can also be set to prioritize temperature or CPU performance. When set to CPU performance priority, control is performed according to the second strategy. When set to temperature optimization, if the TEC power requirement exceeds the maximum power of the power adapter minus the current power consumption of the laptop, the CPU frequency can be throttled to reduce the current power consumption of the laptop and prioritize the TEC temperature control.

[0057] 4. When performing specific temperature control, the PID algorithm can be used to adjust the power of TEC to achieve precise control of the C-surface temperature.

[0058] It can be seen that the embodiment of the present invention only adds two temperature sensors and one TEC module, making full use of the heat pipes and EC originally existing in the laptop to achieve the above functions. The overall solution is simple and reliable, and adds advantages to the laptop at only a small cost.

[0059] The following is further explained:

[0060] Reference Figure 2 , shows a step flow chart of a temperature control method for a mobile terminal provided by an embodiment of the present invention. The mobile terminal can be provided with a metal shell, a first temperature sensor for collecting the temperature of a target area in the metal shell, and a thermoelectric cooler.

[0061] As an example, the mobile terminal may be a laptop computer, a tablet computer, a mobile phone, etc.

[0062] The target area may be the location where the metal shell of the mobile terminal contacts the user, such as the C-side of a laptop or the location of the hand tray in the C-side of a laptop. The thermoelectric cooler may be arranged on one side of the inside of the target area, that is, inside the mobile terminal, such as Figure 1 The middle setting is on the right side of the laptop keyboard and below the palm rest.

[0063] A thermoelectric cooler is a device based on the Peltier effect, which typically consists of two materials and transfers heat from one side of the device to the other while forcing a DC current through it.

[0064] Specifically, the following steps may be included:

[0065] Step 201 : When the mobile terminal is powered on, an expected temperature value for the target area is obtained, and a regional temperature value of the target area collected by the first temperature sensor is obtained.

[0066] After the mobile terminal is powered on, an application deployed in the mobile terminal and used to control the temperature of the target area can obtain an expected temperature value for the target area, that is, a temperature value that the target area is expected to reach.

[0067] Moreover, since the first temperature sensor is deployed in the target area, the real-time regional temperature value of the target area can be collected by the first temperature sensor and transmitted to the application.

[0068] In one embodiment of the present invention, obtaining the expected temperature value for the target area includes:

[0069] An expected temperature value for the target area determined according to current time information is acquired.

[0070] In one embodiment, the current time information may be obtained from the server, and then based on the current time information, the temperature value corresponding to the time information may be obtained from a preset database as the expected temperature value.

[0071] In one embodiment of the present invention, obtaining the expected temperature value for the target area includes:

[0072] A temperature setting interface is provided to the user, and in response to the user's operation on the temperature setting interface, an expected temperature value for the target area is determined.

[0073] In another embodiment, a temperature setting interface may be provided to the user through an application program, and the user may input or select a corresponding temperature value through the temperature setting interface as the expected temperature value.

[0074] Step 202: Determine the required power according to the expected temperature value and the regional temperature value.

[0075] After obtaining the expected temperature value and the regional temperature value, the expected temperature value and the regional temperature value can be compared to determine whether to control the TEC for heating or cooling, and further determine the power consumption required to control the TEC for heating or cooling to reach the expected temperature value, that is, the required power.

[0076] In one embodiment of the present invention, the mobile terminal may further be provided with a second temperature sensor for collecting ambient temperature. The second temperature sensor may be provided above the screen of the mobile terminal, such as at a camera position, so as to accurately collect the ambient temperature. The determining the required power according to the expected temperature value and the regional temperature value may include:

[0077] Acquire the ambient temperature value collected by the second temperature sensor; and determine the required power supply power according to the expected temperature value, the regional temperature value, and the ambient temperature value.

[0078] Since different ambient temperatures require different amounts of power to adjust the temperature to the same degree, after determining the expected temperature value and the regional temperature value, the ambient temperature value collected by the second temperature sensor can be further obtained and combined with the ambient temperature value to determine the required power.

[0079] In one embodiment of the present invention, the mobile terminal may further be provided with a humidity sensor for collecting ambient humidity. The humidity sensor may be provided above the screen of the mobile terminal, such as at a camera position, so as to accurately collect ambient humidity. Before determining the required power according to the expected temperature value and the regional temperature value, the following steps may also be included:

[0080] Acquire the ambient humidity value collected by the humidity sensor; and update the expected temperature value according to the ambient humidity value.

[0081] In order to ensure that the adjusted temperature does not exceed the dew point, condensation does not form on the touch surface, and the use is more reliable, the ambient humidity value can be collected through a humidity sensor. Then, the initially obtained expected temperature value can be adjusted based on the ambient humidity value to avoid condensation on the metal casing of the mobile terminal at the expected temperature value, thereby improving the user experience.

[0082] Step 203 , when the current remaining power of the mobile terminal does not meet the required power, determining the current temperature control mode of the mobile terminal, and determining the target power allocated to the thermoelectric cooler according to the temperature control mode.

[0083] The remaining power can be obtained by subtracting the power currently used by the mobile terminal from the maximum power of the power adapter.

[0084] After determining the required power power, we can further determine whether the current remaining power power of the mobile terminal meets the required power power. When the remaining power power is greater than or equal to the required power power, the remaining power power meets the required power power. When the remaining power power is less than the required power power, the remaining power power does not meet the required power power.

[0085] When the current remaining power of the mobile terminal does not meet the required power, that is, the remaining power is less than the required power, the current temperature control mode of the mobile terminal can be determined, and then the target power allocated to the thermoelectric cooler can be determined according to the temperature control mode.

[0086] In one embodiment of the present invention, determining the target power allocated to the thermoelectric cooler according to the temperature control mode may include:

[0087] When the temperature control mode is the temperature priority mode, the power used by other components in the mobile terminal is reduced, and the target power allocated to the thermoelectric cooler is determined based on the reduction in the power used by other components in the mobile terminal.

[0088] In the temperature priority mode, the power usage of other components in the mobile terminal can be reduced, such as by reducing the CPU frequency to reduce its power usage. Then, the target power power allocated to the thermoelectric cooler can be determined based on the reduction in the power usage of other components in the mobile terminal. That is, the target power power that can be allocated can be equal to the remaining power power of the mobile terminal and the sum of the reduced power power of other components.

[0089] In one embodiment of the present invention, determining the target power allocated to the thermoelectric cooler according to the temperature control mode may include:

[0090] In a case where the temperature control mode is a performance priority mode, the target power allocated to the thermoelectric cooler is determined with the current remaining power of the mobile terminal as the maximum power.

[0091] In performance priority mode (such as CPU performance priority), it is necessary to prioritize the operation of other components such as the CPU and cannot limit their power usage. In this case, the current remaining power of the mobile terminal can only be used as the maximum power and directly used as the target power allocated to the thermoelectric cooler.

[0092] In one embodiment of the present invention, the method may further include:

[0093] In a case where the current remaining power of the mobile terminal meets the required power, a target power allocated to the thermoelectric cooler is determined according to the required power.

[0094] When the current remaining power of the mobile terminal meets the required power, that is, the remaining power is greater than the required power, the required power can be directly determined as the target power.

[0095] Step 204: Control the thermoelectric cooler to control the temperature of the target area according to the target power.

[0096] After the target power is determined, the thermoelectric cooler can be controlled to control the temperature of the target area according to the target power, thereby reaching or approaching the expected temperature value.

[0097] When performing specific temperature control, the PID algorithm can be used to adjust the TEC power to achieve precise control of the C-surface temperature. PID stands for Proportional, Integral, and Differential coefficient, representing three control algorithms. The combination of these three algorithms can effectively correct deviations in the controlled object, thereby achieving a stable state.

[0098] In an embodiment of the present invention, a mobile terminal is provided with a metal casing, a first temperature sensor for collecting the temperature of a target area in the metal casing, and a thermoelectric cooler. The thermoelectric cooler is fitted on one side of the interior of the target area. When the mobile terminal is turned on, an expected temperature value for the target area is obtained, and a regional temperature value of the target area collected by the first temperature sensor is obtained. A required power is determined based on the expected temperature value and the regional temperature value. When the current remaining power of the mobile terminal does not meet the required power, a current temperature control mode of the mobile terminal is determined, and a target power allocated to the thermoelectric cooler is determined based on the temperature control mode. According to the target power, the thermoelectric cooler is controlled to perform temperature control on the target area. This achieves temperature regulation of the area in the casing of the mobile terminal by the thermoelectric cooler, solves the problem of temperature discomfort that usually occurs at the contact point between the metal casing of the mobile terminal and the user, does not require an additional power adapter, has low power consumption, and meets the demand for mobile terminals to be miniaturized and lightweight.

[0099] Reference Figure 3 , shows a step flow chart of another temperature control method for a mobile terminal provided by an embodiment of the present invention, the mobile terminal can be provided with a metal shell, a first temperature sensor for collecting the temperature of a target area in the metal shell, and a thermoelectric cooler.

[0100] As an example, the mobile terminal may be a laptop computer, a tablet computer, a mobile phone, etc.

[0101] The target area may be the location where the metal shell of the mobile terminal contacts the user, such as the C-side of a laptop or the location of the hand tray in the C-side of a laptop. The thermoelectric cooler may be arranged on one side of the inside of the target area, that is, inside the mobile terminal, such as Figure 1 The middle setting is on the right side of the laptop keyboard and below the palm rest.

[0102] A thermoelectric cooler is a device based on the Peltier effect, which typically consists of two materials and transfers heat from one side of the device to the other while forcing a DC current through it.

[0103] Specifically, the following steps may be included:

[0104] Step 301 : When the mobile terminal is powered on, an expected temperature value for the target area is obtained, and a regional temperature value of the target area collected by the first temperature sensor is obtained.

[0105] After the mobile terminal is powered on, an application deployed in the mobile terminal and used to control the temperature of the target area can obtain an expected temperature value for the target area, that is, a temperature value that the target area is expected to reach.

[0106] Moreover, since the first temperature sensor is deployed in the target area, the real-time regional temperature value of the target area can be collected by the first temperature sensor and transmitted to the application.

[0107] Step 302: Determine the required power according to the expected temperature value and the regional temperature value.

[0108] After obtaining the expected temperature value and the regional temperature value, the expected temperature value and the regional temperature value can be compared to determine whether to control the TEC for heating or cooling, and further determine the power consumption required to control the TEC for heating or cooling to reach the expected temperature value, that is, the required power.

[0109] Step 303 : When the current remaining power of the mobile terminal does not meet the required power, determine the current temperature control mode of the mobile terminal.

[0110] The remaining power can be obtained by subtracting the power currently used by the mobile terminal from the maximum power of the power adapter.

[0111] After determining the required power power, we can further determine whether the current remaining power power of the mobile terminal meets the required power power. When the remaining power power is greater than or equal to the required power power, the remaining power power meets the required power power. When the remaining power power is less than the required power power, the remaining power power does not meet the required power power.

[0112] When the current remaining power of the mobile terminal does not meet the required power, that is, the remaining power is less than the required power, the current temperature control mode of the mobile terminal can be determined, and then the target power allocated to the thermoelectric cooler can be determined according to the temperature control mode.

[0113] Step 304: When the temperature control mode is the temperature priority mode, reduce the power used by other components in the mobile terminal, and determine the target power allocated to the thermoelectric cooler based on the reduction in the power used by other components in the mobile terminal.

[0114] In the temperature priority mode, the power usage of other components in the mobile terminal can be reduced, such as by reducing the CPU frequency to reduce its power usage. Then, the target power power allocated to the thermoelectric cooler can be determined based on the reduction in the power usage of other components in the mobile terminal. That is, the target power power that can be allocated can be equal to the remaining power power of the mobile terminal and the sum of the reduced power power of other components.

[0115] Step 305: Control the thermoelectric cooler to control the temperature of the target area according to the target power.

[0116] After the target power is determined, the thermoelectric cooler can be controlled to control the temperature of the target area according to the target power, thereby reaching or approaching the expected temperature value.

[0117] When performing specific temperature control, the PID algorithm can be used to adjust the TEC power to achieve precise control of the C-surface temperature. PID stands for proportional, integral, and differential, representing three control algorithms. The combination of these three algorithms can effectively correct deviations in the controlled object, thereby achieving a stable state.

[0118] Reference Figure 4 , shows a step flow chart of another temperature control method for a mobile terminal provided by an embodiment of the present invention, the mobile terminal can be provided with a metal shell, a first temperature sensor for collecting the temperature of a target area in the metal shell, and a thermoelectric cooler.

[0119] As an example, the mobile terminal may be a laptop computer, a tablet computer, a mobile phone, etc.

[0120] The target area may be the location where the metal shell of the mobile terminal contacts the user, such as the C-side of a laptop or the location of the hand tray in the C-side of a laptop. The thermoelectric cooler may be arranged on one side of the inside of the target area, that is, inside the mobile terminal, such as Figure 1 The middle setting is on the right side of the laptop keyboard and below the palm rest.

[0121] A thermoelectric cooler is a device based on the Peltier effect, which typically consists of two materials and transfers heat from one side of the device to the other while forcing a DC current through it.

[0122] Specifically, the following steps may be included:

[0123] Step 401 : When the mobile terminal is powered on, an expected temperature value for the target area is obtained, and a regional temperature value of the target area collected by the first temperature sensor is obtained.

[0124] After the mobile terminal is powered on, an application deployed in the mobile terminal and used to control the temperature of the target area can obtain an expected temperature value for the target area, that is, a temperature value that the target area is expected to reach.

[0125] Moreover, since the first temperature sensor is deployed in the target area, the real-time regional temperature value of the target area can be collected by the first temperature sensor and transmitted to the application.

[0126] Step 402: Determine the required power according to the expected temperature value and the regional temperature value.

[0127] After obtaining the expected temperature value and the regional temperature value, the expected temperature value and the regional temperature value can be compared to determine whether to control the TEC for heating or cooling, and further determine the power consumption required to control the TEC for heating or cooling to reach the expected temperature value, that is, the required power.

[0128] Step 403 : When the current remaining power of the mobile terminal does not meet the required power, determine the current temperature control mode of the mobile terminal.

[0129] The remaining power can be obtained by subtracting the power currently used by the mobile terminal from the maximum power of the power adapter.

[0130] After determining the required power power, we can further determine whether the current remaining power power of the mobile terminal meets the required power power. When the remaining power power is greater than or equal to the required power power, the remaining power power meets the required power power. When the remaining power power is less than the required power power, the remaining power power does not meet the required power power.

[0131] When the current remaining power of the mobile terminal does not meet the required power, that is, the remaining power is less than the required power, the current temperature control mode of the mobile terminal can be determined, and then the target power allocated to the thermoelectric cooler can be determined according to the temperature control mode.

[0132] Step 404 : When the temperature control mode is the performance priority mode, the target power allocated to the thermoelectric cooler is determined with the current remaining power of the mobile terminal as the maximum power.

[0133] In performance priority mode (such as CPU performance priority), it is necessary to prioritize the operation of other components such as the CPU and cannot limit their power usage. In this case, the current remaining power of the mobile terminal can only be used as the maximum power and directly used as the target power allocated to the thermoelectric cooler.

[0134] Step 405: Control the thermoelectric cooler to control the temperature of the target area according to the target power.

[0135] After the target power is determined, the thermoelectric cooler can be controlled to control the temperature of the target area according to the target power, thereby reaching or approaching the expected temperature value.

[0136] When performing specific temperature control, the PID algorithm can be used to adjust the TEC power to achieve precise control of the C-surface temperature. PID stands for proportional, integral, and differential, representing three control algorithms. The combination of these three algorithms can effectively correct deviations in the controlled object, thereby achieving a stable state.

[0137] Reference Figure 5 , shows a step flow chart of another temperature control method for a mobile terminal provided by an embodiment of the present invention, the mobile terminal can be provided with a metal shell, a first temperature sensor for collecting the temperature of a target area in the metal shell, and a thermoelectric cooler.

[0138] As an example, the mobile terminal may be a laptop computer, a tablet computer, a mobile phone, etc.

[0139] The target area may be the location where the metal shell of the mobile terminal contacts the user, such as the C-side of a laptop or the location of the hand tray in the C-side of a laptop. The thermoelectric cooler may be arranged on one side of the inside of the target area, that is, inside the mobile terminal, such as Figure 1 The middle setting is on the right side of the laptop keyboard and below the palm rest.

[0140] A thermoelectric cooler is a device based on the Peltier effect, which typically consists of two materials and transfers heat from one side of the device to the other while forcing a DC current through it.

[0141] Specifically, the following steps may be included:

[0142] Step 501 : When the mobile terminal is powered on, an expected temperature value for the target area is obtained, and a regional temperature value of the target area collected by the first temperature sensor is obtained.

[0143] After the mobile terminal is powered on, an application deployed in the mobile terminal and used to control the temperature of the target area can obtain an expected temperature value for the target area, that is, a temperature value that the target area is expected to reach.

[0144] Moreover, since the first temperature sensor is deployed in the target area, the real-time regional temperature value of the target area can be collected by the first temperature sensor and transmitted to the application.

[0145] Step 502: Determine the required power according to the expected temperature value and the regional temperature value.

[0146] After obtaining the expected temperature value and the regional temperature value, the expected temperature value and the regional temperature value can be compared to determine whether to control the TEC for heating or cooling, and further determine the power consumption required to control the TEC for heating or cooling to reach the expected temperature value, that is, the required power.

[0147] Step 503 : When the current remaining power of the mobile terminal meets the required power, determine the target power to be allocated to the thermoelectric cooler according to the required power.

[0148] When the current remaining power of the mobile terminal meets the required power, that is, the remaining power is greater than the required power, the required power can be directly determined as the target power.

[0149] Step 504: Control the thermoelectric cooler to control the temperature of the target area according to the target power.

[0150] After the target power is determined, the thermoelectric cooler can be controlled to control the temperature of the target area according to the target power, thereby reaching or approaching the expected temperature value.

[0151] When performing specific temperature control, the PID algorithm can be used to adjust the TEC power to achieve precise control of the C-surface temperature. PID stands for proportional, integral, and differential, representing three control algorithms. The combination of these three algorithms can effectively correct deviations in the controlled object, thereby achieving a stable state.
