Detailed ways

The term "module" used in the following description refers to an application specific integrated circuit (ASIC), electronic circuit, microprocessor, chip, or circuit design that executes one or more software or firmware programs. Modules are configured to perform various algorithms, transformations, and/or logical processing to generate one or more signals. When the module is implemented in software, the module can be implemented in the memory through program execution as a program that can be read by the chip or circuit design.

Please refer to FIG. 1 and FIG. 2 , which illustrates a multi-heat source wireless communication device disclosed in the first embodiment of the present invention, which can perform a temperature management method of multiple heat sources. The multi-heat source wireless communication device includes a wireless communication module 110, a heat source combination, a heat conduction component, a heat dissipation fin set 150, a cooling fan 160 and a temperature management module 170.

As shown in Figure 1, the wireless communication module 110 is used to perform wireless communication. In a specific embodiment, the wireless communication module 110 may be a 5G communication module that supports the fifth generation mobile communication technology (5th generation Mobile Networks), but is not excluded from being a 3G/4G or communication module that supports other wireless communication protocols.

As shown in FIG. 1 , the heat source combination includes multiple heat sources, including but not limited to the central processing unit 122 , the system chipset 124 , the graphics chip 126 , the memory 128 , etc. The system chipset 124 may be, but is not limited to, a combination of a southbridge chip and a northbridge chip, a platform control hub (PCH), a memory controller (MemoryController Hub, MCH), an I/O path controller (I). /O control hub, ICH), AMD Fusion ControllerHub, etc.

As shown in FIG. 1 , the heat-conducting component includes one or more heat pipes 132 and a plurality of heat-conducting sheets 134 , and the heat-conducting sheets 134 respectively contact the wireless communication module 110 and the heat source combination. In the case where the heat source combination has multiple heat sources, each heat source corresponds to one thermal conductive sheet 134, or only some of the heat sources correspond to one thermal conductive sheet 134. Taking this embodiment as an example, the central processor 122 and the system chipset 124 are each provided with a thermal conductive sheet 134, while other heat sources are not configured with a thermal conductive sheet 134 and are not connected to the heat pipe 132. The thermal conductive sheet 134 is made of a high thermal conductive material. For example, the thermal conductive sheet 134 may be a copper sheet. The heat pipe 132 is used to connect each heat conducting sheet 134 . In the case where there is only one heat pipe 132, the heat pipe 132 can be appropriately bent and configured so that each heat conductive sheet 134 is welded to different locations on the heat pipe 132. When there are multiple heat pipes 132 , one or more thermal conductive sheets 134 can be selected to connect two or more heat pipes 132 at the same time to achieve parallel or series connection of the heat pipes 132 . The heat dissipation fin set 150 is connected to the thermal conductive component and is configured corresponding to the heat source combination, especially the central processor 122 ; the heat pipe 132 can be inserted through the heat dissipation fin set 150 , and the heat pipe 132 is positioned adjacent to the central processor 122 ; Or the heat dissipation fin set 150 may be disposed on the heat conductive sheet 134 contacting the CPU 122 .

As shown in FIG. 1 , the cooling fan 160 is fixed to the heat dissipation fin group 150 and is used for forced air cooling of the heat dissipation fin group 150 . In the first embodiment, the cooling fan 160 performs forced air cooling on the heat dissipation fin group 150 at a first rotation speed normally.

As shown in FIG. 2 , the temperature management module 170 is signally connected to the wireless communication module 110 , the heat source combination, and the cooling fan 160 . The temperature management module 170 is used to perform a system detection to detect the temperature value and power consumption of the wireless communication module 110 and the heat source combination. The temperature management module 170 is further used to adjust the power consumption of the wireless communication module 110 and the heat source combination, and adjust the rotation speed of the cooling fan 160 .

The temperature management module 170 can obtain the temperature value through a temperature sensor such as a thermocouple, or directly or indirectly through a basic input and output system (BIOS), through a combination of the wireless communication module 110 and the heat source. Similarly, the temperature management module 170 obtains the power consumption directly or indirectly through the basic input and output system (BIOS), and obtains the report from the wireless communication module 110 and the heat source combination. The power consumption is determined by the working voltage, working current or working frequency of the wireless communication module 110 and the heat source combination. Therefore, increasing or reducing the working voltage, working current and/or working frequency can increase or reduce the power consumption.

The temperature management module 170 may be implemented in hardware or software. When the temperature management module 170 is implemented in software, the CPU 122 loads the program code into the memory 128 and executes it. When the temperature management module 170 is implemented in software, it can be a chip or circuit design.

Referring to FIG. 2 , FIG. 3 and FIG. 4 , the flow of the multi-heat source wireless communication device executing the multi-heat source temperature management method is described as follows.

As shown in Figure 3, the temperature management module 170 sets a first threshold temperature, a second threshold temperature and a third threshold temperature in advance; wherein the third threshold temperature is greater than the second threshold temperature, and the second threshold temperature is greater than the third threshold temperature. A threshold temperature. The temperature management module 170 performs system detection to detect the temperature value and power consumption including detecting the combination of the wireless communication module 110 and the heat source, as shown in step 110 .

For example, when the wireless communication module 110 is a 5G communication module, the best working performance will be achieved when the temperature of the wireless communication module 110 is 60 degrees Celsius. When the temperature value of the wireless communication module 110 exceeds 70 degrees, the performance of the wireless communication module 110 will decline rapidly. Therefore, to maintain the working performance of the wireless communication module 110, it is necessary to avoid the temperature exceeding 70 degrees. At this time, the temperature management module 170 can set the first threshold temperature to 70 degrees and set an appropriate temperature increment value (for example, 5 degrees) to obtain the second threshold temperature value of 75 degrees and the third threshold temperature value of 80 degrees. Spend.

As shown in FIG. 2 and FIG. 3 , the temperature management module 170 determines whether the temperature value of the wireless communication module 110 is greater than the first threshold temperature, as shown in step 120 . When the temperature value of the wireless communication module 110 is greater than the first threshold temperature, the temperature management module 170 determines a second rotational speed that is greater than the first rotational speed, and controls the cooling fan 160 to increase the rotational speed to perform forced air cooling on the heat sink fin group 150 at the second rotational speed. As shown in step 130. In this step, forced air cooling is mainly performed on the central processor 122; since the heat source combination and the wireless communication module 110 are connected by one or more heat pipes 132, after the temperature of the central processor 122 is reduced, the wireless communication module 110 The average temperature in combination with the heat source will also be reduced, so the temperature value of the wireless communication module 110 can be reduced.

As shown in FIGS. 2 and 3 , the temperature management module 170 determines whether the temperature value of the wireless communication module 110 is greater than the second threshold temperature, as shown in step 140 . This step is mainly used to determine whether increasing the fan speed can keep the temperature of the wireless communication module 110 from continuing to rise. If it continues to rise, the temperature management module 170 needs to further perform other temperature management steps. After the rotation speed of the cooling fan 160 is increased to the second rotation speed, if the heat that can be removed is still lower than the combination of the wireless communication module 110 and the heat source, the temperature value of the wireless communication module 110 will continue to rise.

As shown in FIGS. 2 and 3 , when the temperature value of the wireless communication module 110 is greater than the second threshold temperature, the temperature management module 170 reduces the power consumption of the heat source combination, as shown in step 150 . To reduce the power consumption of a heat source combination, you can select the heat source with the largest power consumption to reduce power consumption. For example, the operating voltage, operating current and/or operating frequency of the central processor 122 is reduced.

As shown in FIG. 2 and FIG. 4 , the temperature management module 170 determines whether the temperature value of the wireless communication module 110 is greater than the third threshold temperature, as shown in step 160 . When the temperature value of the wireless communication module 110 is greater than the third threshold temperature, the temperature management module 170 performs an event trigger, as shown in Step 170 . Whether the temperature value of the wireless communication module 110 is greater than the third threshold temperature means that the management plan executed by the temperature management module 170 is no longer sufficient to maintain the temperature value of the wireless communication module 110 below the first threshold temperature, so an event trigger needs to be executed. to change management conditions. Execution of event triggering includes issuing a warning message to prompt the user to further reduce the power consumption of the heat source combination or to reduce the transmission speed of the wireless communication module 110 . Reducing the power consumption of the heat source combination will reduce the operating efficiency of the system; reducing the transmission speed of the wireless communication module 110 will reduce the data transmission efficiency. The temperature management module 170 can change the settings of the first threshold temperature, the second threshold temperature and the third threshold temperature automatically or manually by the user.

The setting of the second rotation speed is mainly determined based on the execution performance of the wireless communication module 110 or the central processor 122 . For example, through prior testing, the cloud database 200 may store a performance comparison table calculated separately by the wireless communication module 110 and the heat source combination (the central processing unit 122 and the system chipset 124). The performance comparison table may include the operating frequency of the CPU 122, the temperature comparison of load changes, the temperature comparison of the system chipset 124 at different hard disk data transmission speeds, and the wireless communication module 110 under different data transmission conditions (download rate and upload rate) temperature comparison.

By setting the performance of the wireless communication module 110 and querying the performance comparison table, the temperature management module 170 can determine the optimal performance distribution of the heat source combination when the wireless communication module 110 maintains the set performance, in conjunction with the heat removal capability of the cooling fan 160 and The relationship between the rotational speed can determine the second rotational speed.

Referring to FIG. 5 and FIG. 6 , a multi-heat source wireless communication device according to a second embodiment of the present invention is shown. The multi-heat source wireless communication device includes a plurality of cooling fans 160 and a heat dissipation fin set 150, wherein at least one cooling fan 160 and at least one heat dissipation fin set 150 correspond to the central processor 122, and at least one cooling fan 160 and at least one heat dissipation fin The slice set 150 corresponds to the wireless communication module 110 . At the same time, the multi-heat source wireless communication device further includes a microphone 180 for detecting a noise of the cooling fan 160 to obtain the volume of the noise. In step 170, because the temperature of the wireless communication module 110 exceeds the third threshold temperature, the event triggered by the temperature management module 170 may be a prompt that the rotation speed of the cooling fan 160 needs to be increased to maintain the transmission of the wireless communication module 110. efficiency. At this time, the temperature management module 170 can provide the option of increasing the rotation speed of the cooling fan 160 for the user to execute, and continuously receives the volume of the noise and generates volume prompt information for the user to increase the second rotation speed to a third rotation speed, and The level of noise is maintained within an acceptable range. Alternatively, the temperature management module 170 can set an upper volume limit, and the third rotation speed is set so that the volume of the noise is not greater than the upper volume limit. The aforementioned volume upper limit can be set by the user.

In addition, during the system detection phase (Step 110 ), the temperature management module 170 detects the type of software being executed to determine the performance load of the wireless communication module 110 or the central processor 122 . For example, when performing Internet access operations, the wireless communication module 110 needs to maintain high transmission efficiency, and the performance of the central processor 122 will be reduced. At this time, the rotation speed of the cooling fan 160 may be increased only for the cooling fan 160 corresponding to the wireless communication module 110 , while the cooling fan 160 corresponding to the central processor 122 maintains the initial first rotation speed. At this time, the rotation speed of the cooling fan 160 can be greatly increased without being limited by the upper limit of the volume. Similarly, if game software is executed and the performance load of the CPU 122 is increased, and the wireless communication module 110 only needs to maintain low transmission efficiency, the speed of the cooling fan 160 can be increased only for the cooling fan 160 corresponding to the CPU 122 Promote.

Referring to FIG. 7 and FIG. 8 , a multi-heat source wireless communication device is disclosed according to a third embodiment of the present invention, which can perform a temperature management method for multiple heat sources. In the third embodiment, the configuration of the cooling fan 160 is omitted.

The temperature management module 170 only sets the second threshold temperature and the third threshold temperature; wherein the third threshold temperature is greater than the second threshold temperature. The second threshold temperature at this time will be set to a lower temperature value, which is approximately equal to the second threshold temperature of the first embodiment. The third threshold temperature can be set to be substantially the same as the third threshold temperature of the first embodiment.

As shown in Figure 9, in the third embodiment, after performing the system detection in Step 110, Step 120 and Step 130 are skipped, and the temperature management module 170 directly executes Step 140 to determine whether the temperature value of the wireless communication module 110 is greater than the second threshold temperature. When the temperature value of the wireless communication module 110 is greater than the second threshold temperature, the temperature management module 170 reduces the power consumption of the heat source combination, as shown in step 150 . When the temperature value of the wireless communication module 110 is greater than the third threshold temperature, the temperature management module 170 performs event triggering, as shown in step 160 and step 170 .

The multi-heat source temperature management method of the present invention monitors changes in the temperature value of the wireless communication module 110 through system detection. When the temperature is too high, the present invention activates different cooling methods one by one to control the temperature value of the wireless communication module 110 within the allowable range to maintain the working efficiency of the wireless communication module 110 . The multi-heat source temperature management method uses multiple cooling methods to avoid the problem of a single cooling method causing a rapid decrease in the overall system performance or excessive fan noise.

Of course, the present invention can also have various other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention. However, these corresponding Changes and deformations should fall within the protection scope of the appended claims of the present invention.
