Description of the Invention: [Technical Field] The present invention relates to a thermal management device and method, and in particular to a suitable application Temperature management device and method for mobile electronic devices. [Prior Art] A mobile electronic device such as a general mobile phone, a smart phone, or a notebook computer includes many components. Conventional temperature management focuses on the most heat-generating components such as a central processing unit (CPU) or a graphics processing unit (GPU). For example, the hardware is designed to facilitate heat dissipation of these components, or The way the pulse frequency cools these components. Traditional temperature management is designed to prevent hardware components from crashing or damaging due to overheating, with an emphasis on maintaining the device itself, regardless of the user's perception. Mobile electronic devices are often in contact with the user's skin, and if overheated, the user may feel uncomfortable or even burnt. In recent years, the operating clock frequency of various hardware components has rapidly increased, and it has been able to meet the needs of most users. It is no longer appropriate to pursue speed and ignore heat. In addition, the use of Internet, multimedia and communication technologies is becoming more and more diverse. The types of mobile electronic devices are becoming more and more complicated. In some models, the most heated component is no longer a central processing unit and graphics processing unit, but other components, such as a mobile phone's communication module or battery charger. Mobile electronic devices with many functions' different functions are usually handled by different components, for example

The number of the above components is not limited, and there may be only one or more. Each of the above components has a corresponding temperature sensor to measure the temperature thereof, and a corresponding outer casing portion, when the user touches the corresponding outer casing portion, a corresponding user touch signal is triggered, and A corresponding touchdown should be 1 to the sensation of the $4 (four) dragon time touch signal. The outer casing portion corresponding to each of the above components is the outer casing 110 of the mobile electronic device 100, and is most susceptible to the temperature of the component. In the present embodiment, the touch sensors 131 to 133 correspond to the temperature sensing states 141 to 143, respectively. For the sake of brevity, the above elements are not shown green in Figures i and 2. In the present embodiment, the 'per-side touch sensing ^m to 133 splitting filaments are placed in the temperature sensors 141 to 143, respectively, at the same positions as their corresponding members.

If the touch sensor has sufficient _ sensitivity, even if it does not require actual skin contact, as long as the user and the case are within a certain distance, even if the clothing is touched, the touch sensor will be reduced to the eye. The t_sensor 131 133 receives the user's touch signal and can notify the controller 120 by issuing an interrupt. If the user touches at least the outer shell portion of the rainbow, the corresponding user touches the cymbal, and the temperature of at least one of the components corresponding to the touched outer shell portion is higher than a preset threshold. 'Control if m will manage the tree ride temperature that meets the above conditions until the temperature of the above-mentioned components is all below _ below the corresponding critical value, or the user stops touching the above-mentioned outer casing portion. Controller 120 can include a table that is used to store the threshold values for each of the above components. For each component, the corresponding critical value is the upper temperature limit of the component for which the temperature is not higher than a preset value. For the user's power, the temperature of the housing U0 should not exceed the human body temperature, otherwise the user will feel discomfort or even burn. Therefore, in this embodiment, the preset value must be less than or equal to the human body temperature. The temperature management of the component by the controller 120 refers to the use of various techniques to lower the component temperature below a corresponding critical value. For example, as shown in FIG. 3, in the embodiment of FIG. 3, the control ti 120 includes a frequency control unit 15A. For components that operate according to the clock signal, the frequency control unit can reduce the operating rate of the component, to manage the component tear temperature, and cool the component; the frequency control A 150 can also suspend the component operation clock.

If a component supports at least one communication protocol and supports a plurality of different communication frequencies, the frequency control unit 150 can reduce the communication frequency of the component to perform temperature management on the component to cool the component. For example, a communication module supporting a 3G communication protocol is necessarily compatible with a 2G communication protocol. If the temperature exceeds a corresponding threshold, the frequency control unit 150 can control the communication module to use a 2G communication protocol to send and receive messages or data. Since the 2G communication frequency is lower than the 3G communication frequency, this allows the component to enter the low frequency operation and reduce the component temperature. 4 is a flow chart of a temperature management method in accordance with an embodiment of the present invention.

Figure 5 may show the state of the controller 120 of Figure 1, or the state of the apparatus performing the method of Figure 4. If the user does not touch any part of the housing of the mobile electronic device, the user is in a conventional state 510 to perform conventional temperature management of the mobile electronic device. If the shell portion is touched by the user and triggers the user to touch the signal, then the scanning state 520 is entered, and the touch sensors corresponding to each shell portion are scanned one by one to determine which shell or portions are touched, and Check the temperature of each component corresponding to the part of the shell being touched. If only one component of the mobile electronic device is hot, there is a part of the housing that needs to be detected, and only one touch 'sensor' does not have to be scanned one by one. After the handle is swept, if the corresponding part of the component is touched by the user and the user touches the signal, and the temperature of the component itself is higher than the corresponding critical value, the temperature is lowered to 53G, and the condition is met.
