Detailed Description
The term "module" as used in the following description refers to an Application Specific Integrated Circuit (ASIC), an electronic circuit, a microprocessor, a chip executing one or more software or firmware programs, a circuit design. The modules are configured to perform various algorithms, transformations, and/or logic processes to generate one or more signals. When the module is implemented in software, the module may be implemented in memory as a chip, a circuit design readable program by program execution.
Referring to fig. 1 and fig. 2, a multi-heat source wireless communication device according to a first embodiment of the invention can perform a multi-heat source temperature management method. The multi-heat source wireless communication device comprises a wireless communication module 110, a heat source assembly, a heat conducting component, a heat dissipation fin set 150, a cooling fan 160 and a temperature management module 170.
As shown in fig. 1, the wireless communication module 110 is configured to perform wireless communication. In one embodiment, the wireless communication module 110 may be a 5G communication module supporting the fifth generation mobile communication technology (5 th generationMobile Networks), but is not limited to a 3G/4G or other wireless communication protocol supporting communication module.
As shown in FIG. 1, the heat source assembly includes a plurality of heat sources including, but not limited to, a CPU 122, a system chipset 124, a graphics chip 126, a memory 128, and the like. The system chipset 124 may be, but is not limited to, a combination of a south bridge chip and a north bridge chip, a platform path controller (platform control hub, PCH), a memory controller (Memory Controller Hub, MCH), an I/O control hub (ICH), AMD Fusion Controller Hub, etc.
As shown in fig. 1, the heat conducting component includes one or more heat pipes 132 and a plurality of heat conducting fins 134, and the heat conducting fins 134 contact the wireless communication module 110 and the heat source assembly, respectively. In the case where the heat source combination has a plurality of heat sources, each of the heat sources corresponds to one of the heat conductive sheets 134, or only a part of the heat sources corresponds to one of the heat conductive sheets 134. For example, in this embodiment, one heat conducting fin 134 is disposed on each of the cpu 122 and the system chipset 124, and the other heat sources are not disposed with the heat conducting fin 134 and are not connected to the heat pipe 132. The heat conductive sheet 134 is made of a high heat conductive material, for example, the heat conductive sheet 134 may be a copper sheet. The heat pipes 132 are used to connect the respective heat conductive fins 134. In the case of only one heat pipe 132, the heat pipes 132 may be appropriately folded and configured, so that each heat conducting fin 134 is welded to a different portion of the heat pipe 132. In the case of a plurality of heat pipes 132, one or more heat conducting fins 134 may be selected to connect more than two heat pipes 132 simultaneously, so as to achieve parallel connection or series connection of the heat pipes 132. The heat dissipation fin set 150 is connected to the heat conduction component and is configured corresponding to the heat source combination, in particular to the cpu 122; the heat pipe 132 may be disposed through the heat sink fin set 150, such that the heat pipe 132 is located adjacent to the cpu 122; or the heat sink fin set 150 may be disposed on the heat conducting plate 134 contacting the cpu 122.
As shown in fig. 1, the cooling fan 160 is fixed to the heat sink fin group 150, and is used for forced air cooling of the heat sink fin group 150. In the first embodiment, the cooling fan 160 normally performs forced air cooling on the fin set 150 at a first rotation speed.
As shown in fig. 2, the temperature management module 170 is in signal connection with the wireless communication module 110, the heat source assembly, and the cooling fan 160. The temperature management module 170 is configured 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 configured 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 may obtain the temperature value by a temperature sensor such as a thermocouple, or may directly or indirectly obtain the temperature value by a Basic Input Output System (BIOS) and a return of the combination of the wireless communication module 110 and the heat source. Similarly, the temperature management module 170 obtains power consumption directly or indirectly through a Basic Input Output System (BIOS), and obtains the power consumption from the wireless communication module 110 and the return of the heat source combination. The power consumption is determined by the operating voltage, operating current, or operating frequency of the wireless communication module 110 and the heat source combination, and thus, the power consumption may be increased or decreased by increasing or decreasing the operating voltage, operating current, and/or operating frequency.
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 and executes the program codes into the memory 128. When the temperature management module 170 is implemented in software, it may be a chip or a circuit design.
Referring to fig. 2, 3 and 4, a flow of a method for performing temperature management of multiple heat sources by the multi-heat source wireless communication device is described as follows.
As shown in fig. 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 first threshold temperature. The temperature management module 170 performs system detection to detect the temperature and power consumption of the combination of the wireless communication module 110 and the heat source, as shown in Step 110.
For example, in the case that the wireless communication module 110 is a 5G communication module, the wireless communication module 110 has an optimal operation performance when the temperature is 60 ℃. When the temperature of the wireless communication module 110 exceeds 70 degrees, the performance of the wireless communication module 110 will quickly decline. Therefore, to maintain the operation performance of the wireless communication module 110, it is necessary to avoid the temperature value exceeding 70 degrees. At this time, the temperature management module 170 may set the first threshold temperature to 70 degrees, and set the appropriate temperature increment value (e.g. 5 degrees), so as to obtain the second threshold temperature value to 75 degrees and the third threshold temperature value to 80 degrees one by one.
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 a 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 rotation speed greater than the first rotation speed, and controls the cooling fan 160 to increase the rotation speed to perform forced air cooling on the heat sink fin set 150 at the second rotation speed, as shown in Step 130. In this step, forced air cooling is mainly performed for the cpu 122; since the heat source assembly is connected to the wireless communication module 110 by one or more heat pipes 132, the average temperature between the wireless communication module 110 and the heat source assembly is reduced after the temperature of the cpu 122 is reduced, so that the temperature value of the wireless communication module 110 can be reduced.
As shown in fig. 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 the temperature of the wireless communication module 110 can be maintained from rising when the fan speed is increased, and if the temperature is increased, the temperature management module 170 needs to further execute other temperature management steps. After the rotation speed of the cooling fan 160 is increased to the second rotation speed, if the amount of 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 still continuously increases.
As shown in fig. 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. The power consumption of the heat source combination is reduced, and the heat source with the largest power consumption can be selected to execute the power consumption reduction. For example, the operating voltage, operating current, and/or operating frequency of the central processing unit 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 a 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. The condition that the temperature value of the wireless communication module 110 is greater than the third threshold temperature represents that the management scheme performed by the temperature management module 170 is insufficient to maintain the temperature value of the wireless communication module 110 below the first threshold temperature, and therefore an event trigger is performed to change the management condition. Executing the event trigger includes sending an alert message to alert the user that the power consumption of the heat source assembly needs to be further reduced or that the transmission speed of the wireless communication module 110 is reduced. Reducing the power consumption of the heat source combination will reduce the system operating efficiency; reducing the transmission speed of the wireless communication module 110 will result in a reduction in data transmission efficiency. The temperature management module 170 may change the settings of the first threshold temperature, the second threshold temperature, and the third threshold temperature automatically or manually via a user switch.
The second rotation speed is set according to the execution performance of the wireless communication module 110 or the cpu 122. For example, through a previous test, the cloud database 200 may store a performance map of the wireless communication module 110 and the heat source combination (the cpu 122 and the system chipset 124) separately operated. The performance table may include a comparison of the operating frequency of the cpu 122, a comparison of the temperature of the load change, a comparison of the temperature of the system chipset 124 at different hard disk data transmission speeds, and a comparison of the temperature of the wireless communication module 110 at different data transmission conditions (download rate and upload rate).
Through setting the performance of the wireless communication module 110 and querying the performance map, 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, and can determine the second rotation speed in cooperation with the relationship between the heat removal capacity of the cooling fan 160 and the rotation speed.
Referring to fig. 5 and 6, a multi-heat source wireless communication device according to a second embodiment of the invention is shown. The multi-heat source wireless communication device comprises 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 processing unit 122, and at least one cooling fan 160 and at least one heat dissipation fin set 150 correspond to the wireless communication module 110. Meanwhile, the multi-heat source wireless communication device further comprises a microphone 180 for detecting a noise of the cooling fan 160 to obtain the volume of the noise. In Step 170, since the temperature of the wireless communication module 110 exceeds the third threshold temperature, the event triggering performed by the temperature management module 170 may be an indication of the need to further increase the rotation speed of the cooling fan 160 to maintain the transmission efficiency of the wireless communication module 110. At this time, the temperature management module 170 may provide the option of increasing the rotation speed of the cooling fan 160 for the user to execute, and continuously receive the volume of the noise and generate the volume prompt message, so that the user can increase the second rotation speed to a third rotation speed, and the volume of the noise is maintained within an acceptable range. Alternatively, the temperature management module 170 may set a volume upper limit, and the third rotation speed is set such that the volume of the noise is not greater than the volume upper limit. The upper limit of the volume can be set by the user.
In addition, during the system test phase (Step 110), the temperature management module 170 tests the type of software being executed to determine the performance load of the wireless communication module 110 or the cpu 122. For example, when performing the internet operation, the wireless communication module 110 needs to maintain high transmission efficiency, and the performance of the cpu 122 is 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, and the initial first rotation speed may be maintained corresponding to the cpu 122. At this time, the rotation speed of the cooling fan 160 can be greatly increased without being limited by the upper volume limit. Similarly, if the performance load of the cpu 122 is increased and the wireless communication module 110 only needs to maintain low transmission efficiency when executing the game software, the rotation speed of the cooling fan 160 is increased, and the rotation speed of the cooling fan 160 corresponding to the cpu 122 can be increased.
Referring to fig. 7 and 8, a multi-heat source wireless communication device according to a third embodiment of the invention can perform a multi-heat source temperature management method. In the third embodiment, the configuration of the cooling fan 160 is omitted.
The temperature management module 170 sets only 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 is set to a lower temperature value approximately equal to the second threshold temperature of the first embodiment. The third threshold temperature may be set to be substantially the same as the third threshold temperature of the first embodiment.
As shown in fig. 9, in the third embodiment, after the system detection is performed in Step 110, step 120 and Step 130 are skipped, and the temperature management module 170 directly performs 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 temperature management method of the multiple heat sources of the present invention monitors the temperature value change of the wireless communication module 110 through system detection. When the temperature is too high, the present invention starts different cooling means one by one to control the temperature value of the wireless communication module 110 to be within the allowable range, so as to maintain the working efficiency of the wireless communication module 110. The temperature management method of multiple heat sources adopts multiple cooling means, so that the problems of rapid reduction of the overall efficiency of the system or overlarge noise of a fan caused by a single cooling means can be avoided.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
