Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a heat dissipation method and related equipment. Background Art

[0002] With the improvement of science and technology, mobile phones have become an indispensable communication device in people's daily life. People use mobile phones for longer and longer periods of time. Long-term use will cause the mobile phone to heat up, affecting the service life of the mobile phone. Therefore, mobile phone cooling devices (such as mobile phone cooling cases) have become a market demand. However, the cooling cases currently on the market need to be opened or closed manually, which is not convenient enough. Summary of the invention

[0003] A heat dissipation method and related equipment provided in the embodiments of the present application are helpful to improve the timeliness and convenience of heat dissipation of mobile phones.

[0004] In a first aspect, a heat dissipation method is provided, which can be applied to a first device. The first device can be, for example, a mobile phone. The method includes: the first device is connected to a second device, the second device is a device for heat dissipation; the first device detects the temperature of the first device; the first device controls the heat dissipation state of the second device according to the temperature, and the heat dissipation state includes: starting heat dissipation, stopping heat dissipation, and heat dissipation power.

[0005] In the embodiment of the present application, the first device can automatically control the heat dissipation state of the second device according to the local temperature. On the one hand, manual operation by the user is not required, and the operation is relatively convenient. On the other hand, if the heat dissipation state is adaptively controlled according to the temperature, it can ensure that the heat dissipation state is adapted to the temperature. For example, it can avoid the situation where the temperature is low but the heat is being dissipated all the time, resulting in a waste of power consumption, or avoid the situation where the temperature is high but the heat is not being dissipated, resulting in a shortened device life.

[0006] In a possible design, the first device controls a heat dissipation state of the second device according to the temperature, including:

[0007] When the temperature is higher than a first threshold, the first device controls the second device to start heat dissipation; or,

[0008] When the temperature is lower than a second threshold, the first device controls the second device to stop heat dissipation; or,

[0009] After the second device starts to dissipate heat, the first device controls the heat dissipation power to be positively correlated with the temperature;

[0010] The second threshold is less than or equal to the first threshold.

[0011] In an embodiment of the present application, the first device can start heat dissipation in time when the temperature is high to protect the first device, and stop heat dissipation in time when the temperature is low to avoid wasting power consumption; moreover, after the second device starts heat dissipation, as the temperature of the first device decreases, the heat dissipation power of the second device can be reduced to avoid high-power heat dissipation all the time and waste power consumption.

[0012] In one possible design, the first device controls the heat dissipation state of the second device according to the temperature, including: the first device controls the charging state of the first device charging the second device according to the temperature, and when the charging state changes, the heat dissipation state of the second device changes accordingly; wherein the charging state includes: at least one of starting charging, stopping charging, and charging power.

[0013] In the embodiment of the present application, the first device can charge the second device. The first device can control the heat dissipation state of the second device by controlling the charging state of the second device. In this way, the storage capacity of the second device is relatively low, and it can be as light and thin as possible.

[0014] In a possible design, the first device controls, according to the temperature, a charging state of the first device charging the second device, including:

[0015] When the temperature is higher than a first threshold, the first device starts charging the second device;

[0016] When the temperature is lower than a second threshold, the first device stops charging the second device;

[0017] When the first device charges the second device, the first device controls the charging power to be positively correlated with the temperature;

[0018] The second threshold is less than or equal to the first threshold.

[0019] In an embodiment of the present application, when a first device with a wireless reverse charging function charges a second device, it can automatically start or stop charging the second device according to the temperature of the first device to control the second device to start or stop heat dissipation; moreover, after the second device starts to dissipate heat, the heat dissipation power of the second device can be controlled to be positively correlated with the temperature, thereby avoiding waste of power consumption caused by continuous high-power heat dissipation.

[0020] In a possible design, when the charging state changes, the heat dissipation state of the second device changes accordingly, including:

[0021] When the first device starts to charge the second device, the second device starts to dissipate heat;

[0022] When the first device stops charging the second device, the second device stops dissipating heat;

[0023] After the first device charges the second device, the heat dissipation power of the second device is positively correlated with the charging power.

[0024] In the embodiment of the present application, the first device can charge the second device. The first device can control the heat dissipation state of the second device by controlling the charging state of the second device. In this way, the storage capacity of the second device is relatively low, and it can be as light and thin as possible.

[0025] In one possible design, the first device includes a switch, and the switch is used to control the wireless reverse charging function of the first device, where the wireless reverse charging function is a function for the first device to wirelessly charge other devices; when the temperature is higher than a first threshold, the first device starts to charge the second device, including: when the temperature is higher than the first threshold, the first device controls the switch to be in an on state, and the first device starts to charge the second device; when the temperature is lower than a second threshold, the first device stops charging the second device, including: when the temperature is lower than the second threshold, the first device controls the switch to be in a off state, and the first device stops charging the second device.

[0026] In an embodiment of the present application, the state of the switch in the first device for controlling the wireless reverse charging function can change with the temperature of the first device. For example, when the temperature of the first device is high, the switch is in the on state, and the first device starts to charge the second device so that the second device starts to dissipate heat. When the temperature of the first device is low, the switch is in the off state, and the first device stops charging the second device so that the second device stops dissipating heat. In this process, there is no need for the user to manually trigger the switch, which is convenient to operate, and the first device controls the switch state according to the temperature of the device, which can not only improve the timeliness of heat dissipation, but also avoid wasting power consumption.

[0027] In one possible design, the first device includes an icon. When the temperature is higher than a first threshold, the first device controls the icon to be in a first state, and when the icon is in the first state, the switch is in an on state; when the temperature is lower than a second threshold, the first device controls the icon to be in a second state, and when the icon is in the second state, the switch is in a off state.

[0028] In the embodiment of the present application, the user can determine the state of the switch by the state of the icon, and then determine the charging state, which provides a better experience.

[0029] In one possible design, after the first device controls the switch to be in an on state, it also includes: when the first device receives an operation for closing the switch, the first device controls the switch to be in an off state, and the first device stops charging the second device; and / or, after the first device controls the switch to be in an off state, it also includes: when the first device receives an operation for turning on the switch, the first device controls the switch to be in an on state, and the first device starts charging the second device.

[0030] In the embodiment of the present application, the way in which the first device controls the switch according to the temperature can be called the automatic mode, and the way in which the user manually controls the switch can be called the manual mode. After the first device uses the automatic mode to control the switch to be turned on or off, the user can operate manually. For example, after the first device automatically controls the switch to be turned on according to the temperature, the user can manually turn it off; or, after the first device automatically controls the switch to be turned off according to the temperature, the user can manually turn it on. In short, the manual mode has a higher priority than the automatic mode to ensure that the user experience is prioritized.

[0031] In one possible design, after the first device receives an operation for turning off the switch and controls the switch to be in a closed state, the method further includes: within a first preset time period, the switch remains in the closed state, and the state of the switch does not change with changes in the temperature of the first device.

[0032] In the embodiment of the present application, after the first device automatically controls the switch to turn on according to the temperature, the user can manually turn it off. Since the temperature has not dropped, the first device may trigger the switch to turn on again according to the temperature. In order to avoid this situation, after the user manually turns off the switch, the first device controls the switch to remain in the off state to prioritize the user experience.

[0033] In a possible design, the method further includes: after the first device detects that a condition is met, controlling the state of the switch according to the temperature of the first device; wherein the condition includes at least one of the following:

[0034] The switch remains in the closed state for a period of time that reaches the first preset period of time; or,

[0035] The first device is restarted; or,

[0036] The first device reconnects to the second device; or,

[0037] The first device detects that the user manually controls the switch to enter an on state, and the switch remains in the on state for a time period that reaches a third preset time period.

[0038] In an embodiment of the present application, after the first device automatically controls the switch to turn on according to the temperature, the user can manually turn it off. In order to avoid the switch being triggered to turn on again due to high temperature in a short period of time, after the user manually turns off the switch, the first device controls the switch to remain in the closed state. When the first device detects that the conditions are met, it controls the state of the switch according to the temperature. In short, after the first device uses the automatic mode to control the switch to turn on or off, the user can operate manually. After the user manually operates, the automatic mode is prohibited for a short period of time, and after the conditions are met, the prohibition of the automatic mode is cancelled. Therefore, the manual mode has a higher priority than the automatic mode to ensure that the user experience is prioritized.

[0039] In one possible design, after the first device receives an operation to turn on the switch and controls the switch to be in an on state, the method further includes: within a second preset time period, the switch remains in the on state, and the state of the switch does not change with changes in the temperature of the first device.

[0040] In the embodiment of the present application, after the first device is turned off according to the temperature control switch, the user can manually turn it on. In order to avoid the switch automatically turning off again in a short time, after the user manually turns on the switch, the first device controls the switch to remain on to give priority to user experience.

[0041] In a possible design, the method further includes: after the first device detects that a condition is met, controlling the state of the switch according to the temperature of the first device; wherein the condition includes at least one of the following:

[0044] The first device reconnects to the second device; or,

[0045] The first device detects that the user manually controls the switch to enter an off state, and the time duration for which the switch remains in the off state reaches a fourth preset time duration.

[0046] In the embodiment of the present application, after the first device is turned off using the automatic mode control switch, the user can manually turn it on. After the user manually operates, the automatic mode is prohibited for a short period of time, and the prohibition of the automatic mode is cancelled after the conditions are met. Therefore, the manual mode has a higher priority than the automatic mode, ensuring that the user experience is prioritized.

[0047] In one possible design, after the first device is connected to the second device, the first device further includes: the first device outputs a first prompt message, and the first prompt message is used to prompt the second device to be in place. In the embodiment of the present application, the first device outputs a prompt after connecting to the second device to facilitate the user to determine whether the second device is in place, thereby improving the user experience.

[0048] In one possible design, before the first device charges the second device, the first device also includes: determining that the current remaining power is greater than or equal to the first power. In the embodiment of the present application, the first device charges the second device when determining that the current remaining power is large, so as to avoid the first device being shut down due to low remaining power.

[0183] The at least one involved in the embodiments of the present application includes one or more; wherein, more than one means greater than or equal to two. In addition, it should be understood that in the description of this specification, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as an explicit or implicit relative importance, nor can they be understood as an explicit or implicit order. For example, the first device and the second device do not represent the importance of the two or the order of the two, but are only for distinguishing the description. In the embodiments of the present application, "and / or" is only a description of the association relationship, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship.

[0184] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the specification. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0185] As used in this specification, the term “when” or “after” may be interpreted to mean “if” or “after” or “in response to determining that” or “in response to detecting that”, depending on the context. Similarly, the phrase “upon determining that” or “if (stated condition or event) is detected” may be interpreted to mean “if determining that” or “in response to determining that” or “upon detecting (stated condition or event)” or “in response to detecting (stated condition or event)”, depending on the context.

[0229] Figure 2B The software structure diagram of the electronic device provided in the embodiment of the present application. The electronic device may be the first device in the system, such as a mobile phone. Figure 2B As shown, the software structure of the electronic device can be a layered structure, and the electronic device can be a terminal in the system. The layered architecture is to divide the software into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. The layered architecture can be, for example, an event-driven architecture, a micro-kernel architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application is based on the layered architecture. The system is taken as an example to illustrate the software structure of the electronic device. The system is divided into five layers, from top to bottom: application layer, application framework layer, Android runtime and system library, kernel layer and hardware layer.

[0230] like Figure 2B As shown, the application layer can include a series of application packages, such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, video and other applications.

[0231] The application framework layer provides application programming interface (API) and programming framework for the applications in the application layer. The application framework layer includes some predefined functions. Figure 2B As shown, the application framework layer may include a heat dissipation shell control system. The heat dissipation shell control system includes a temperature control service and a power management service. Among them, the temperature control service is used to read the temperature and control the heat dissipation state of the heat dissipation shell according to the temperature. For example, the heat dissipation state includes starting heat dissipation or stopping heat dissipation. The power management service is used to control the opening or closing of the wireless reverse charging function. When the wireless reverse charging function is turned on, wireless charging is performed to other devices (for example, the heat dissipation shell). When the wireless reverse charging function is turned off, charging to other devices (for example, the heat dissipation shell) is stopped. Optionally, Figure 2B In the example above, the temperature control service and the power management service are located in the application framework layer. It is understandable that the temperature control service and the power management service can also be located in other layers, such as the system library or the application layer. The temperature control service and the power management service can be in the same layer or in different layers. The specific execution steps of the temperature control service and the power management service will be described in the following section. Fig.13 and Fig.14 Introduced in.

[0232] It is understandable that although Figure 2BAlthough not shown in the figure, the application framework layer may also include a content provider, a view system, a phone manager, a resource manager, a notification manager, etc. The content provider is used to store and obtain data and make the data accessible to the application. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc. The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface including a text message notification icon may include a view for displaying text and a view for displaying pictures. The phone manager is used to provide communication functions for electronic devices. For example, the management of call status (including connected, hung up, etc.). The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, etc. The notification manager enables the application to display notification information in the status bar, which can be used to convey notification-type messages and can disappear automatically after a short stay without user interaction. For example, the notification manager is used to notify the completion of downloads, message reminders, etc. The notification manager can also be a notification that appears in the top status bar of the system in the form of an icon or scroll bar text, such as a notification of an application running in the background, or a notification that appears on the screen in the form of a dialog window. For example, a text message is prompted in the status bar, a prompt sound is emitted, an electronic device vibrates, an indicator light flashes, etc.

[0233] Android Runtime includes core libraries and virtual machines. Android runtime is responsible for scheduling and management of the Android system. The core library consists of two parts: one is the function that the Java language needs to call, and the other is the Android core library. The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform object life cycle management, stack management, thread management, security and exception management, and garbage collection.

[0234] The system library can include multiple functional modules. For example: surface manager, media library, 3D graphics processing library (for example: OpenGL ES), 2D graphics engine (for example: SGL), etc. Among them, the surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications. The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc. The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis, and layer processing, etc. The 2D graphics engine is a drawing engine for 2D drawing.

[0235] The kernel layer is the layer between hardware and software. The kernel layer includes at least wifi driver, display driver, camera driver, audio driver, sensor driver, etc.

[0236] The hardware layer includes one or more cameras, and may also include other hardware such as sensors, displays, radio transmitters, etc. Among them, the radio transmitter is used to transmit radio to charge other devices.

[0237] Understandably, Figure 2B The software structure shown does not constitute a specific limitation on the software structure of the electronic device. The software structure of the electronic device in the embodiment of the present invention may include: Figure 2B More or fewer modules in Figure 2B More or fewer layers, or a layer contains more than Figure 2B More or fewer modules, etc. In addition, Figure 2B The combination / connection relationship between modules can also be adjusted and modified.

[0238] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0239] As the functions of mobile phones are improved, people use mobile phones more and more frequently. If you use a mobile phone for a long time, the mobile phone will heat up. The heating of the mobile phone will not only affect the user experience, but also affect the service life of the mobile phone. There are mobile phone heat dissipation devices on the market, such as mobile phone heat dissipation shells (hereinafter referred to as heat dissipation shells). A switch is provided on the heat dissipation shell to control the heat dissipation shell to start or stop heat dissipation. For example, when the switch on the heat dissipation shell is pressed by the user, the heat dissipation shell starts to dissipate heat. When the switch on the heat dissipation shell is popped up, the heat dissipation shell stops dissipating heat. It should be understood that this method requires a switch to be set on the heat dissipation shell, so the volume of the heat dissipation shell will be relatively large. After the heat dissipation shell is installed on the mobile phone, it is more difficult for the user to hold the mobile phone, and the convenience of operating the mobile phone is reduced. In addition, the heat dissipation shell is located on the back of the mobile phone, and the user operates on the front of the mobile phone. If you need to click the switch on the heat dissipation shell, you need to turn it over to operate, which is more cumbersome.

[0240] In the embodiment of the present application, the mobile phone can control the heat dissipation shell to start or stop heat dissipation. In this way, there is no need to set a switch on the heat dissipation shell, which can be made thin and light. Moreover, since the mobile phone can control the heat dissipation shell, the user does not need to turn the phone over to operate, which is more convenient.

[0241] One possible implementation method is to set a switch on the mobile phone, which is used to control the heat dissipation shell to start or stop heat dissipation. It should be noted that the switch mentioned in this article can be an icon on the foreground of the mobile phone, or it can be a switch set in the background of the mobile phone (for example, a piece of software code in the background of the mobile phone can realize the function of the switch). If it is a switch in the background of the mobile phone, in order to facilitate user operation, an icon can be displayed in the foreground, which can be used to control the switch. For example, when the icon is in a certain state, the switch is turned on, and when the icon is in another state, the switch is turned off. For the sake of ease of understanding, the following mainly takes the example of the switch being an icon in the foreground of the mobile phone as an example.

[0242] For example, see Figure 3 , the mobile phone displays interface 301. Interface 301 includes icon 302. Icon 302 is a switch for controlling the heat dissipation shell to start or stop heat dissipation. It should be noted that, Figure 3 In the example, interface 301 is an interface of the control center in the mobile phone. In fact, it can also be other interfaces, such as an interface in the setting application in the mobile phone, which is not limited in the embodiment of the present application. Optionally, icon 302 can always exist in interface 301, or, when the mobile phone is not connected to the heat dissipation shell, icon 302 is not displayed in interface 301, and after the mobile phone is connected to the heat dissipation shell, icon 302 is displayed in interface 301. Among them, the way in which the mobile phone controls the heat dissipation shell to start or stop heat dissipation through the switch (i.e., icon 302) includes the following method A or method B.

[0243] In mode A, the user manually triggers a switch (ie, icon 302 ) to control the heat dissipation housing to start or stop heat dissipation.

[0244] For example, see Figure 4A (a), the mobile phone displays interface 301. Interface 301 includes icon 302. At this time, icon 302 is in a closed state (for example, icon 302 is not highlighted, and highlighting includes highlighting, bolding, etc.). When the mobile phone receives an operation (for example, clicking) on ​​icon 302, it displays the following Figure 4A (b) interface 303, in which icon 302 is in an on state (for example, icon 302 is highlighted, and highlighting includes highlighting, bolding, etc.). After icon 302 is in the on state, the mobile phone background controls the heat dissipation shell to start heat dissipation. Figure 4A In (b), when the mobile phone receives an operation (e.g., click) on icon 302, it returns to Figure 4A In the interface 301 of (a), the icon 302 is in the off state. After the icon 302 is in the off state, the mobile phone background controls the heat dissipation shell to stop heat dissipation.

[0245] In mode B, the mobile phone can automatically control the switch (ie, icon 302) to control the heat dissipation shell to start or stop heat dissipation.

[0246] For example, the mobile phone automatically controls the switch (i.e., icon 302) according to the temperature of the mobile phone to control the heat dissipation shell to start or stop heat dissipation. Figure 4B (a), the mobile phone displays interface 301. Interface 301 includes icon 302. At this time, icon 302 is in a closed state. When the mobile phone determines that the temperature of the mobile phone is higher than the first threshold, the display is as follows: Figure 4B (b) interface 303. Icon 302 in interface 303 is turned on, so the mobile phone controls the heat dissipation shell to start dissipating heat. When the mobile phone background detects that the local temperature is less than the second threshold, the front desk returns to Figure 4B (a) interface 301, icon 302 is in the closed state. At this time, the mobile phone controls the heat dissipation shell to stop heat dissipation. The second threshold is less than or equal to the first threshold.

[0247] Please compare the corresponding Figure 4A Corresponding to method B Figure 4B . Figure 4A In the example, the transition from (a) to (b) or from (b) to (a) is manually performed by the user. Figure 4B In the example, the movement from (a) to (b) or from (b) to (a) is automatically controlled by the mobile phone. Figure 4B The method does not require manual operation by the user, and the operation is convenient. In addition, the mobile phone controls the start and stop of the heat dissipation shell according to the temperature of the mobile phone, which can achieve timely heat dissipation without wasting power. For example, when the temperature of the mobile phone is too high, the heat dissipation shell is controlled to start heat dissipation and reduce the temperature of the mobile phone in time. When the temperature of the mobile phone is low, the heat dissipation shell is controlled to stop heat dissipation to avoid wasting power.

[0248] Optionally, the mobile phone can only use method A (for example, the factory default configuration can only use method A), or only use method B (for example, the factory default configuration can only use method B), or both method A and method B can be used, and the user can set the mobile phone to use method A or method B. For the convenience of description, method A can be called manual mode, and method B can be called automatic mode. The user can set the mobile phone to use manual mode or automatic mode. For example, when the first device receives a first operation for setting the automatic mode, the automatic mode is used. When the first device receives a second operation for setting the manual mode, the manual mode is used. For example, see Figure 5 (a), the mobile phone displays an interface 501, and the interface 501 includes an automatic mode option 502. Optionally, the interface 501 may be an interface in a mobile phone setting application or other interfaces, which is not limited in the embodiment of the present application. It should be noted that, Figure 5 In (a), option 502 is in an unselected state. When the mobile phone receives an operation for option 502 (i.e., the first operation), the following is displayed: Figure 5 (b) Interface 503. Option 502 in interface 503 is in a selected state, so the mobile phone uses the automatic mode, that is, mode B. Figure 5 In (b), when the mobile phone receives an operation for option 502 (i.e., the second operation), it returns Figure 5 In the interface 501 of (a), option 502 is selected, so the mobile phone uses the manual mode, namely mode A. As mentioned above, in mode B, the mobile phone uses the first threshold and the second threshold in the process of controlling the switch (i.e., icon 302) according to the temperature of the mobile phone. The first threshold and the second threshold can be set by the user. For example, Figure 5 (b) Interface 503 may also display a line 504 and a slider 505 for setting the first threshold, as well as prompt information, such as "automatically dissipate heat when the temperature exceeds the first threshold." After the user understands the function of the first threshold according to the prompt information, the user may change the position of the slider 505 on line 504. For example, the further to the left the position is, the lower the first threshold is, and the further to the right the position is, the higher the first threshold is. Figure 5(b), the interface 503 may also display a line 506 and a slider 507 for setting the second threshold, as well as prompt information, such as "the temperature is lower than the second threshold and the heat dissipation stops automatically". After the user knows the role of the second threshold according to the prompt information, the position of the slider 507 on the line 506 can be changed. For example, the more to the left, the lower the second threshold, and the more to the right, the higher the second threshold. It can be understood that the second threshold is less than or equal to the first threshold, so after the user sets the first threshold, the mobile phone can display a mark 508 on the line 506 to indicate that the slider 507 can only move within the left range of the mark 508 on the line 506 and cannot exceed the mark 508. In short, the user can set the temperature threshold (first threshold) for turning on the trigger switch (i.e., icon 302) and the temperature threshold (second threshold) for turning off the trigger switch (i.e., icon 302) by himself, which provides a better experience.

[0249] When the phone is set to manual mode, the automatic mode is disabled. The automatic mode is disabled, which can be understood as the phone not executing the processing flow of the automatic mode, such as not detecting the temperature and controlling the start or stop of the heat sink according to the temperature. Figure 4B In automatic mode, the state of the switch (i.e., icon 302) changes with the temperature. When the temperature is higher than the first threshold, icon 302 is in the on state, and when the temperature is lower than the second threshold, icon 302 is in the off state. Therefore, from the mobile phone UI, the automatic mode is disabled, that is, the state of the switch (i.e., icon 302) does not change with the temperature. In this case, icon 302 can only be triggered manually by the user, that is, using manual mode.

[0250] When the phone is set to automatic mode, the manual mode can still be used. In short, the manual mode has a higher priority than the automatic mode. Once the phone is set to manual mode, the automatic mode cannot be used, but after the phone is set to automatic mode, the manual mode can be used. In this way, user needs can be prioritized. The following are two examples.

[0251] Example 1: After the mobile phone determines that the temperature is greater than the first threshold, it automatically starts the switch (i.e., icon 302) to control the heat dissipation shell to start heat dissipation. The user can manually turn off the switch to control the heat dissipation shell to stop heat dissipation. A possible scenario is that after the mobile phone is set to automatic mode, the user is using the mobile phone for call services (e.g., voice or video calls). When the call time is long, the mobile phone will heat up. When the mobile phone detects that the temperature is higher than the first threshold, it automatically triggers the switch (e.g., icon 302) to start to control the heat dissipation shell to start heat dissipation. Since the heat dissipation shell will generate noise after it is started, it will affect the call quality. At this time, the user can manually turn off the switch to control the heat dissipation shell to stop heat dissipation. It should be noted that in this scenario, in order not to affect the call quality, the user manually turns off the switch to stop heat dissipation, but the temperature of the mobile phone does not drop, so the mobile phone will continue to execute the automatic mode processing flow, that is, the mobile phone will automatically turn on the switch again to start heat dissipation. In order to avoid this situation, the mobile phone can disable the automatic mode after detecting that the user manually stops heat dissipation. For example, after the mobile phone detects that the user manually turns off the switch, it can control the switch to remain in the off state within the first preset time, that is, the mobile phone will not control the state of the switch according to the temperature within the first preset time, that is, the state of the switch does not change with the change of temperature. When the mobile phone detects that the first condition is met, the disablement of the automatic mode is canceled. Among them, canceling the disablement of the automatic mode means that the mobile phone background can execute the processing flow of the automatic mode, and the state of the switch (i.e., icon 302) can change with the change of temperature in the mobile phone UI. Among them, the first condition includes at least one of the following:

[0252] (1) The disabling time reaches a first preset time. That is, after the mobile phone has disabled the automatic mode for a period of time, the disabling of the automatic mode will be automatically cancelled.

[0253] (2) The phone is restarted. That is, after the phone is restarted, the automatic mode is disabled.

[0254] (3) The heat sink is reinstalled. That is, after the user reinstalls the heat sink, the automatic mode is disabled.

[0255] (4) The user manually controls the switch to enter the on state, and the switch remains in the on state for a third preset time period.

[0256] Taking (4) above as an example, after the mobile phone automatically turns on the switch according to the temperature, the user manually turns off the switch. If the switch remains on for a third preset time (for example, 2 minutes, 5 minutes), it automatically switches to automatic mode. For example, the mobile phone uses automatic mode by default. Suppose the user is currently using the mobile phone to make a call. During the call, the temperature of the mobile phone rises, and the background uses the automatic mode to control the switch to turn on to start heat dissipation. Suppose the user manually turns off the switch due to noise, then the switch will remain off. Suppose the user manually turns on the switch after ending the call. At this time, the switch will remain on for a period of time (the third preset time). After the third preset time, the mobile phone enters automatic mode again.

[0257] Example 2: After the mobile phone determines that the temperature is lower than the second threshold value and automatically turns off the switch (i.e., icon 302) to control the heat dissipation shell to stop heat dissipation, the user can manually turn on the switch to control the heat dissipation shell to start heat dissipation. A possible scenario is that the temperature of the mobile phone has dropped below the second threshold value, so the mobile phone automatically turns off the switch (i.e., icon 302) to stop heat dissipation. However, due to some reasons (such as the second threshold value is high), the user still feels hot. At this time, the user can manually turn on the switch (i.e., icon 302) to continue heat dissipation. It should be noted that in this scenario, after the mobile phone automatically turns off the switch, the user turns on the switch, but the temperature of the mobile phone is already lower than the second threshold value, so the mobile phone will continue to execute the processing flow of the automatic mode, that is, the mobile phone will automatically turn off the switch again to stop heat dissipation. In order to avoid this situation, the mobile phone can disable the automatic mode after detecting that the user manually turns on the heat dissipation. For example, after the mobile phone detects that the user manually turns on the switch, the switch can be controlled to remain in the turned-on state within the second preset time length, that is, within the second preset time length, the mobile phone will not control the state of the switch according to the temperature, that is, the state of the switch does not change with the change of temperature. When the mobile phone detects that the second condition is met, the disablement of the automatic mode is cancelled. The second condition includes at least one of the following:

[0258] (1) The disabled time reaches a second preset time.

[0259] (2) Restart your phone.

[0260] (3) Reinstall the heat sink.

[0261] (4) The user manually controls the switch to enter the off state, and the switch remains in the off state for a period of time that reaches a fourth preset period of time.

[0262] In the above embodiment, the mobile phone has a switch (e.g., icon 302) that can be used to control the heat dissipation shell to start or stop heat dissipation. In specific implementation, the mobile phone controls the heat dissipation shell to start or stop heat dissipation through the switch (e.g., icon 302), which can include the following method 1 or method 2.

[0263] Method 1: The mobile phone and the heat dissipation shell can communicate. The mobile phone can send control information to the heat dissipation shell, and the control information is used to control the heat dissipation shell to start or dissipate heat. For example, when the switch is in the on state, the mobile phone sends control information 1 to the heat dissipation shell, and control information 1 is used to indicate the start of heat dissipation. When the switch is in the off state, the mobile phone sends control information 2 to the heat dissipation shell, and control information 2 is used to indicate the stop of heat dissipation. Among them, whether the switch is in the on state or the off state can be manually controlled by the user (that is, the manual mode mentioned above) or automatically controlled by the mobile phone according to the temperature (that is, the automatic mode mentioned above).

[0264] Method 2: The mobile phone can charge the heat dissipation shell. For example, when the switch is in the on state, the mobile phone starts to charge the heat dissipation shell, and the heat dissipation shell starts to dissipate heat. When the switch is in the off state, the mobile phone stops charging the heat dissipation shell, and the heat dissipation shell stops dissipating heat. Among them, whether the switch is in the on state or the off state can be manually controlled by the user (that is, the manual mode in the previous text) or automatically controlled by the mobile phone according to the temperature (that is, the automatic mode in the previous text). It should be noted that the charging in this article can be wireless charging or wired charging. For example, when the mobile phone and the heat dissipation shell are wiredly connected, the charging method can be wired charging. The mobile phone and the heat dissipation shell are wirelessly connected (for example, connected by magnetic induction), and the charging method can be wireless charging. Taking wireless charging as an example, the mobile phone needs to have a wireless reverse charging function. The so-called wireless reverse charging refers to the mobile phone as a power source to wirelessly charge other devices. The heat dissipation shell acts as a radio receiving end to receive the wireless charging of the mobile phone.

[0265] By comparing the first method and the second method, it can be seen that in the first method, the switch is used to control the device to send control information to the heat dissipation shell to control the heat dissipation shell to start or stop heat dissipation. In the second method, the switch is used to control the device to start or stop charging the heat dissipation shell to control the heat dissipation shell to start or stop heat dissipation. Therefore, if the mobile phone uses the first method, the switch can be icon 302. If the mobile phone adopts the second method, the switch can be icon 302, or it can also be a switch for controlling the wireless reverse charging function of the mobile phone. For example, see Figure 6 , the mobile phone displays interface 601. Interface 601 includes icon 602. Icon 602 is used to control the opening or closing of the wireless reverse charging function of the mobile phone. It should be noted that, Figure 6 In the example, the interface 601 is the interface of the control center in the mobile phone. In fact, it can also be other interfaces, such as an interface in the setting application in the mobile phone, which is not limited in the embodiment of the present application. Among them, the mobile phone controls the way of starting or stopping the charging of the heat dissipation shell by the switch (i.e., icon 602), including the following method C or method D.

[0266] Mode C: The user manually triggers the switch (i.e., icon 602) to start or stop the wireless reverse charging function of the mobile phone. When the wireless reverse charging function is started, the mobile phone charges the heat dissipation shell. When the wireless reverse charging function is stopped, the mobile phone stops charging the heat dissipation shell. For example, see Fig. 7A (a), the mobile phone displays interface 601. Interface 601 includes icon 602. At this time, icon 602 is in a closed state. When the mobile phone receives an operation (e.g., click) on icon 602, it displays the following Fig. 7A (b) Interface 603. Icon 602 in interface 603 is turned on. The mobile phone starts the wireless reverse charging function and starts charging the heat dissipation shell. After the heat dissipation shell is charged, it starts to dissipate heat. Fig. 7A In (b), when the mobile phone receives an operation on icon 602, it returns to Fig. 7A (a) interface 601. Icon 602 is in the on state. The mobile phone turns off the wireless reverse charging function and stops charging the heat dissipation shell. The heat dissipation shell stops dissipating heat after charging stops.

[0267] Mode D: The mobile phone automatically controls the switch (i.e., icon 602) to control the mobile phone to start or stop charging the heat dissipation case. For example, the mobile phone automatically controls the switch (i.e., icon 602) according to the temperature of the mobile phone. For example, see Figure 7B (a), the mobile phone displays an interface 601. The interface 601 includes an icon 602. The icon 602 is in a closed state. When the mobile phone detects that the temperature is higher than the first threshold, the display is as follows: Figure 7B (b) Interface 603. Icon 602 in interface 603 is in an on state. At this time, the wireless reverse charging function is started in the background of the mobile phone to start charging the heat dissipation shell. Figure 7B In (b), when the mobile phone detects that the temperature is lower than the second threshold, the foreground returns to Figure 5 (a) interface 501. Icon 602 is in a closed state. The wireless reverse charging function is turned off in the background of the mobile phone, and charging to the heat dissipation shell is stopped.

[0268] Please compare the corresponding Fig. 7A Corresponding to method D Figure 7B . Fig. 7A In the example, the transition from (a) to (b) or from (b) to (a) is manually performed by the user. Figure 7B In the example above, the transition from (a) to (b) or from (b) to (a) is automatically controlled by the mobile phone background. Figure 7BIn this method, there is no need for manual operation by the user, and the operation is convenient. Moreover, the mobile phone controls whether to charge the heat dissipation shell according to the temperature of the mobile phone, and then controls the heat dissipation shell to start or stop heat dissipation, so that the heat dissipation can be timely and power consumption is not wasted. For example, when the temperature of the mobile phone is too high, the heat dissipation shell starts to charge, so that the heat dissipation shell starts to dissipate heat and the temperature of the mobile phone is reduced in time. For another example, when the temperature of the mobile phone drops, the heat dissipation shell stops charging, so that the heat dissipation shell stops dissipating heat, avoiding power consumption.

[0269] Optionally, the mobile phone can only use mode C (for example, the factory default configuration can only use mode C), or only use mode D (for example, the factory default configuration can only use mode D), or both mode C and mode D can be used. The user can set the mobile phone to use mode C or mode D. For the convenience of description, mode C can be called manual mode and mode D can be called automatic mode. The user can set the mobile phone to use manual mode or automatic mode. For example, see Figure 8 (a), the mobile phone displays interface 801. Interface 801 includes option 802 for automatic mode. Optionally, interface 801 may be an interface in a mobile phone setting application or other interface, which is not limited in the present embodiment. It should be noted that when option 802 is not selected, it is in the automatic mode state. Figure 8 In the state (a), the mobile phone uses manual mode, namely mode C. Figure 8 In (a), when the mobile phone receives an operation for option 802, the following is displayed: Figure 8 (b) interface 803. Option 802 in interface 803 is selected. Therefore, the mobile phone uses the automatic mode, that is, mode D. Optionally, Figure 8 In (b), the mobile phone may also display a line 804 and a slider 805 for setting the first threshold, as well as a prompt message, such as "automatically charging when the temperature exceeds the first threshold." After the user understands the function of the first threshold according to the prompt message, the user may change the position of the slider 805 on the line 804. For example, the further to the left the position is, the lower the first threshold is, and the further to the right the position is, the higher the first threshold is. Optionally, Figure 8 In (b), the mobile phone may also display a line 806 and a slider 807 for setting the second threshold, as well as a prompt message, such as "charging automatically stops when the temperature is lower than the second threshold". After the user knows the function of the second threshold according to the prompt message, the position of the slider 807 on the line 806 can be changed. For example, the further to the left the position is, the lower the second threshold is, and the further to the right the position is, the higher the second threshold is. It can be understood that the second threshold is less than or equal to the first threshold, so after the user sets the first threshold, the mobile phone can display a mark 808 on the line 806 to indicate that the slider 807 can only move within the range to the left of the mark 808 on the line 806 and cannot exceed the mark 808.

[0270] When the mobile phone is set to manual mode (i.e., mode C), the automatic mode is disabled. When the mobile phone is set to automatic mode (i.e., mode D), the manual mode can still be used. That is, the priority of the manual mode is higher than that of the automatic mode. For this part, please refer to Example 1 and Example 2 above. You only need to replace the icon 302 in Example 1 and Example 2 above with icon 602. For the sake of brevity, it will not be repeated.

[0271] It should be noted that when a mobile phone has a wireless reverse charging function, it can charge not only the heat dissipation case but also other devices. One possible implementation method is that when a mobile phone is connected to another device, it can determine whether the device is a heat dissipation case. If it is a heat dissipation case, it can determine whether the current mode is set to automatic mode or manual mode. If it is manual mode, use method C, and if it is automatic mode, use method D. If the device connected to the mobile phone is not a heat dissipation case, the mobile phone only uses the manual mode and does not use the automatic mode. The implementation process of the mobile phone determining whether the device connected to it is a heat dissipation case will be described later. Fig. 9 Introduced in.

[0272] The following embodiments are mainly described by taking the automatic mode as an example.

[0273] See also Fig. 9 , is a flow chart of a heat dissipation method provided in an embodiment of the present application. The method can be applied to a system, such as Figure 1 The system shown. Fig. 9 , the process includes:

[0274] S901, a first device is connected to a second device.

[0275] Among them, "connection" includes: wired connection or wireless connection. Alternatively, "connection" may also include: connection through Bluetooth, Near Field Communication (NFC), etc. Alternatively, "connection" may also include: connection through magnetic induction. For example, a Hall sensor is provided on the first device, and a magnetic device is provided on the second device. When the Hall sensor on the first device senses the magnetic device on the second device, it is determined that the first device is connected to the second device. In this way, S301 can be refined into the first device sensing the second device. Among them, the principle of electromagnetic induction between the Hall sensor and the magnetic device is not introduced in detail in the embodiments of the present application.

[0276] Optionally, after the first device is connected to the second device, the first device may output prompt information 1, which is used to prompt the second device that the connection is successful or that the second device is in place. For example, prompt information 1 may be vibration, ringing, or may also be information such as text and / or pictures displayed on the display screen of the first device.

[0277] Optionally, after the first device is connected to the second device, the device model of the second device may be read, and the first device determines whether the second device is a heat dissipation device according to the device model. If so, S902 is executed.

[0278] S902, the first device detects the temperature of the device.

[0279] Exemplarily, a temperature sensor is provided in the first device for detecting the temperature of the device.

[0280] Optionally, before S902, the first device may further perform the step of determining whether the current mode of the first device is the automatic mode. If it is the automatic mode, perform S903; otherwise, the manual mode may be used. Figure 5 or Figure 8 The interface shown determines whether the current mode of the first device is the automatic mode, which will not be repeated here. The manual mode has been described above and will not be repeated.

[0281] S903, the first device controls the heat dissipation state of the second device according to the temperature, where the heat dissipation state includes: starting heat dissipation, stopping heat dissipation, and heat dissipation power.

[0282] For example, S903 may include any one of the following (1) to (4):

[0283] (1) When the temperature is higher than a first threshold, the first device controls the second device to start heat dissipation.

[0284] (2) When the temperature is lower than a second threshold, the first device controls the second device to stop heat dissipation.

[0285] The second threshold is less than or equal to the first threshold. The first threshold may be a default setting of the first device system or a user-specified setting. The second threshold may be a default setting of the first device system or a user-specified setting. For the method of user-specifying the first threshold and the second threshold, please refer to the above text. Figure 5 or Figure 8 , which will not be repeated here.

[0286] As mentioned above, a switch may be set on the first device, and the switch is used to control the second device to start or stop heat dissipation. Therefore, S903 may include: the first device controls the switch to be in an on state or a off state according to the temperature. When the switch is in the on state, the second device is controlled to start heat dissipation. When the switch is in the off state, the second device is controlled to stop heat dissipation. The switch may be Figure 3 Icon 302 in, or, Figure 6Assuming that the switch is icon 302, S903 can adopt the above method one, that is, the first device and the second device can communicate. For example, when the temperature of the first device is higher than the first threshold, the first device controls the switch to be in the on state, and the first device sends control information 1 to the second device, and control information 1 is used to indicate the start of heat dissipation. When the temperature of the first device is lower than the second threshold, the first device controls the switch to be in the off state, and the first device sends control information 2 to the second device, and control information 2 is used to indicate the stop of heat dissipation. Assuming that the switch is icon 602, the first device can adopt the above method two, that is, the first device can charge the second device. For example, when the temperature of the first device is higher than the first threshold, the first device controls the switch (i.e., icon 602) to be in the on state, the first device starts to charge the second device, and the second device starts to dissipate heat. When the temperature of the first device is lower than the second threshold, the first device controls the switch to be in the off state, the first device stops charging the second device, and the second device stops dissipating heat.

[0287] (3) After the second device starts to dissipate heat, the first device controls the heat dissipation power of the second device to be positively correlated with the temperature.

[0288] In an embodiment of the present application, after the first device controls the second device to start dissipating heat, it can also control the heat dissipation power of the second device to change with the temperature according to the temperature. For example, after the second device starts to dissipate heat, the temperature of the first device gradually decreases, and correspondingly, the heat dissipation power of the second device also decreases, which can save power consumption. For another example, after the second device starts to dissipate heat, the temperature of the first device may rise again (for example, the user uses the first device to play games, watch videos, make phone calls, etc.). At this time, the first device can control the heat dissipation power of the second device to increase to cool down as soon as possible. Optionally, the heat dissipation power of the second device is positively correlated with the temperature of the first device, including: the heat dissipation power of the second device changes linearly or nonlinearly with the temperature of the first device. Taking linear change as an example, when the temperature of the first device rises, the heat dissipation power of the second device increases in real time, and when the temperature of the first device decreases, the heat dissipation power of the second device decreases in real time. Taking nonlinear changes as an example, when the temperature of the first device increases by [0 degrees, 5 degrees), the heat dissipation power of the second device remains unchanged. When the temperature of the first device increases by greater than or equal to 5 degrees, the heat dissipation power of the second device increases by ΔP; or, when the temperature of the first device decreases by [0 degrees, 5 degrees), the heat dissipation power of the second device remains unchanged. When the temperature of the first device decreases by greater than or equal to 5 degrees, the heat dissipation power of the second device decreases by ΔP.

[0289] If the first device uses the above method 1 (i.e., the first device and the second device can communicate), the first device can send control information to the second device to control the second device to increase or decrease the heat dissipation power. For example, when the temperature of the first device decreases, control information 3 is sent to the second device, and control information 3 is used to instruct to reduce the heat dissipation power. When the temperature of the first device increases, control information 4 is sent to the second device, and control information 4 is used to instruct to increase the heat dissipation power.

[0290] If the first device uses the second method above (that is, the first device can charge the second device), then the first device can adjust the charging power of the second device according to the temperature to adjust the heat dissipation power of the second device. Among them, the charging power is positively correlated with the temperature, and the heat dissipation power of the second device is positively correlated with the charging power. For example, when the temperature of the first device decreases, the first device reduces the charging power to the second device to reduce the heat dissipation power of the second device. When the temperature of the first device increases, the first device increases the charging power to the second device to increase the heat dissipation power of the second device. Exemplarily, the charging power is positively correlated with the temperature of the first device, including: the charging power changes linearly or nonlinearly with the temperature of the first device. Similarly, the heat dissipation power of the second device is positively correlated with the charging power, including: the heat dissipation power of the second device changes linearly or nonlinearly with the charging power. Taking nonlinear change as an example, the first device stores the corresponding relationship between temperature and charging power, as shown in the following table:

[0291] temperature Charging power Above 30 degrees Power 1 20-30 degrees Power 2, less than power 1 Below 10-20 degrees Power 3, less than power 2 Below 10 degrees 0

[0292] In this way, the first device can determine the corresponding charging power according to the current temperature. When the temperature is different, the charging power is different, and the heat dissipation power of the second device is different.

[0293] See also Fig.10 , is another flow chart of the heat dissipation method provided in one embodiment of the present application. Fig.10 It can be understood that Fig. 9 Refinement, for example, Fig.10 S1003 to S1009 are Fig. 9 A refinement of S903 in . Fig.10 , the process includes:

[0294] S1001, a first device is connected to a second device.

[0295] S1002, the first device detects the temperature of the device.

[0296] Among them, the implementation principle of S1001-S1002 is the same as Fig. 9 The implementation principles of S901-S902 are the same and will not be repeated.

[0297] S1003, the first device determines whether the temperature is higher than the first threshold. If so, execute S1004, otherwise, S1002 may be executed immediately or after waiting for a first time period, S1002 may be executed. The first time period may be a pre-set temperature detection cycle, such as 30 seconds, and the specific time is not limited in the embodiment of the present application.

[0298] S1004, the first device determines whether the remaining power is greater than the first power. If so, execute S1005, otherwise, output prompt information 2, prompt information 2 is used to prompt whether to charge the second device. When the first device receives the confirmation instruction, execute S1005.

[0299] The first power level may be pre-set or user-specified, and is not limited in the embodiment of the present application.

[0300] Optionally, S1004 may be executed or not, so it is indicated by a dotted line in the figure. If S1004 is executed, that is, the first device charges the second device when the remaining power is sufficient, the first device can be prevented from automatically shutting down due to low power. If S1004 is not executed, that is, when the first device determines that the temperature is higher than the first threshold, it directly charges the second device regardless of the remaining power, which can ensure that the first device dissipates heat in time and prevent the mobile phone from overheating and causing damage to the device.

[0301] S1005: The first device starts charging the second device.

[0302] Optionally, before the first device charges the second device, it may first determine the charging power adapted to the second device to prevent the second device from being burned out due to excessively high charging power, or the second device from being unable to start in time due to excessively low charging power. Among them, the first device determines the charging power adapted to the second device, which may include: the first device determines the device model of the second device, and determines the charging power according to the device model of the second device. For example, a corresponding relationship is stored in the first device, and the corresponding relationship includes the charging power corresponding to different device models. After the first device determines the device model of the second device, it may determine the charging power corresponding to the device model of the second device based on the corresponding relationship. After determining the charging power, the first device charges the second device based on the charging power. In the foregoing, there are multiple ways for the first device to determine the device model of the second device, for example, the first device sends a query instruction to the second device, the query instruction is used to query the device model of the second device, the first device receives the query result returned by the second device, and the query result is used to indicate the device model of the second device.

[0303] In some embodiments, after the first device starts charging the second device, the charging power of the first device charging the second device may change with the temperature of the first device. For example, when the temperature of the first device decreases, the charging power decreases, and correspondingly, the heat dissipation power of the second device decreases. For example, when the temperature of the first device increases, the charging power increases, and correspondingly, the heat dissipation power of the second device increases.

[0304] S1006: The second device starts to dissipate heat.

[0305] S1007, the first device determines whether the temperature is lower than the second threshold. If so, execute S1008, otherwise, return to continue to execute S1007, for example, return to immediately execute S1007 or wait for a second time period before executing S1007. The second time period may be pre-set. The second time period may be the same as or different from the first time period.

[0306] S1008: The first device stops charging the second device.

[0307] S1009: The second device stops heat dissipation.

[0308] As described above, a switch (e.g., icon 602) is provided on the first device. The first device can control whether to charge the second device through the switch. Therefore, when the first device detects that the temperature is higher than the first threshold, the control switch is in the on state, and the first device starts to charge the second device so that the second device starts to dissipate heat. When the first device detects that the temperature is lower than the second threshold, the control switch is in the off state, and the first device stops charging the second device so that the second device stops dissipating heat.

[0309] It is understandable that, during the process of charging the second device from the first device, the remaining power of the first device gradually decreases. Optionally, before S1007, if the first device detects that the remaining power is less than the second power, it can output prompt information 3 to prompt the user whether to continue charging. If a confirmation instruction is received, charging continues until the temperature is lower than the second threshold value. If a cancellation instruction is received, charging the second device is stopped. Among them, the second power is less than or equal to the first power, and the specific value is not limited in the embodiment of this application.

The heat sink control system in the first device reads the temperature through the temperature sensor. When the heat sink control system determines that the temperature is higher than the first threshold, it notifies the radio transmitter to start powering. After the radio receiver in the second device receives the radio, it drives the radiator to dissipate heat. When the heat sink control system determines that the temperature is lower than the second threshold, it notifies the radio transmitter to stop powering. The radiator in the second device stops dissipating heat.
