[0016] This application proposes an electronic device and a temperature control method therefor to solve the problems mentioned in the background art. To make the features and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings.

[0020] Figure 1 This is a block diagram of an electronic device according to an embodiment of this application. The electronic device 10 includes a fan 110, a current-blocking module 120, a battery 130, and a control module 140. The electronic device 10 further includes a heating module 150 and a processor 160.
[0021] As described above, the fan 110 is used to dissipate first (system) heat energy (indicated by arrows in the figure) within the electronic device 10. The flow-blocking module 120 is disposed on a dissipation path of the first heat energy. The control module 140 is electrically connected to the flow-blocking module 120. The control module 140 may be disposed next to the battery 130. The control module 140 is used to measure a temperature of the battery 130 and determine whether the temperature is below a threshold (e.g., 10 degrees Celsius). When the temperature is below the threshold, the control module 140 controls a state of the flow-blocking module 120 to dissipate (e.g., all or part) the first heat energy to the battery 130, thereby increasing or maintaining the temperature of the battery 130. When the temperature is not lower than the threshold, the control module 140 controls the state of the flow-blocking module 120 to prevent the first heat energy from dissipating to the battery 130 (e.g., directly blowing it out of the electronic device 10).
[0022] In other words, as described above, in low-temperature environments, the electronic device of this application can utilize existing heat sources to raise or maintain the temperature of the battery.
[0023] In some embodiments, the control module 140 can determine whether the electronic device 10 is in a first operating state or a second operating state. The first operating state may include a normal use state of the electronic device 10, and the second operating state may include a standby state (or sleep power-saving mode) of the electronic device 10, but this application is not limited thereto. When the electronic device 10 is in the first operating state and the temperature is below the threshold, the control module 140 can control the state of the flow-blocking module 120 to allow (e.g., all or part of) the first heat energy to escape to the battery 130, thereby increasing or maintaining the temperature of the battery 130. When the electronic device 10 is in the first operating state and the temperature is not lower than the threshold, the control module 140 can control the state of the flow-blocking module 120 to prevent the first heat energy from escaping to the battery (e.g., directly blowing it out of the electronic device 10).
[0024] In some embodiments, the heating module 150 may be disposed adjacent to the battery 130 and electrically connected to the control module 140. In some embodiments, when the electronic device 10 is in the second operating state and the temperature is below the threshold, the control module 140 may control the heating module 150 to turn on, triggering the heating module 150 to provide second heat energy to the battery, thereby increasing or maintaining the temperature of the battery 130. When the electronic device 10 is in the second operating state and the temperature is not lower than the threshold, the control module 140 may control the heating module 150 to turn off. That is, when the electronic device is in standby mode, there is no existing (system) heat source available. At this time, heat energy can be provided by the heating module instead.
[0025] In some embodiments, when the electronic device 10 is in the first operating state and the temperature is below the threshold, the control module 140 can control the heating module 150 to turn on, triggering the heating module 150 to provide second heat energy to the battery, thereby increasing or maintaining the temperature of the battery 130. That is, in low-temperature environments, in addition to utilizing the system heat source, the heating module can also be turned on to more effectively increase or maintain the battery temperature.
[0026] In some embodiments, the heating module 150 may be further electrically connected to an outer layer (not shown) of the battery 130, and the outer layer of the battery 130 comprises a thermally conductive material. For example, the thermally conductive material may comprise a thermally conductive but non-conductive adhesive (e.g., aluminum nitride (AlN), ceramic, graphite, epoxy compounds, etc.), a thermally conductive and conductive adhesive (e.g., graphite, copper, gold, silver, aluminum, etc.), or a combination thereof, but this application is not limited thereto.
[0027] In some embodiments, the state may include a switch state. When the switch state is on, the first thermal energy can pass through the flow-blocking module 120, such as... Figure 2 As shown. Figure 2 This is a block diagram of an electronic device when the switch is in the ON state, according to an embodiment of this application. Figure 2 The dashed line indicates that the flow obstruction module (e.g., a return orifice) is open. When the switch is closed, the first heat energy can bypass the flow obstruction module 120 (e.g., be directly blown out of the electronic device 10).
[0028] In some embodiments, the state may include an inclined state relative to the dissipation path. When the inclined state is perpendicular to the dissipation path, the first heat energy may not pass through the flow-blocking module 120 (e.g., it may be directly blown out of the electronic device 10). When the inclined state is not perpendicular to the dissipation path, the first heat energy can pass through the flow-blocking module 120, such as... Figure 3 As shown. Figure 3 This is a block diagram of an electronic device according to an embodiment of this application when the tilt state is not perpendicular to the dissipation path. For example, the current-blocking module is in the state of being either on or unblocked until the battery temperature is not lower than a threshold.
[0029] In some embodiments, a default state of the flow-blocking module 120 is to be off or blocked, so that (all) of the first heat energy flows to the outside of the electronic device 10.
[0030] In some embodiments, the battery 130 may be a lithium battery. The electronic device 10 may include at least one of a laptop computer and a portable device, but this application is not limited thereto.
[0031] In some embodiments, a source of the first thermal energy may include the processor 160 in the electronic device. The processor may include at least one of a central processing unit (CPU), a graphics processing unit (GPU), and a neural processing unit (NPU), but this application is not limited thereto.
[0032] Based on the above embodiments, the following temperature control methods for processing electronic devices can be obtained (e.g., summarized as follows). Figure 4 This is a schematic flowchart illustrating a temperature control method for electronic devices according to an embodiment of this application. Figure 4 As shown, this temperature control method includes the following steps:
[0033] In step S402, the temperature of the battery in the electronic device is measured, and then step S404 is executed.
[0034] In step S404, it is determined whether the electronic device is in a first operating state or a second operating state. If the electronic device is in the first operating state, step S406 is executed. If the electronic device is in the second operating state, step S408 is executed.
[0035] In step S406, it is determined whether the temperature is lower than a threshold. If the temperature is lower than the threshold, step S410 is executed. If the temperature is not lower than the threshold, step S412 is executed.
[0036] In step S408, it is determined whether the temperature is lower than the threshold. If the temperature is lower than the threshold, step S414 is executed. If the temperature is not lower than the threshold, step S416 is executed.
[0037] In step S410 (i.e., when the electronic device is in the first operating state and the temperature is below the threshold), the state of the current-blocking module in the electronic device is controlled so that the first heat energy in the electronic device can be dissipated to the battery, and then step S412 is executed.
[0038] In step S412 (i.e., when the electronic device is in the first operating state and the temperature is not lower than the threshold), the state of the current blocking module is controlled so that the first heat energy is not dissipated to the battery, and then step S414 is executed.
[0039] In step S414 (i.e., when the electronic device is in the second operating state and the temperature is below the threshold), the heating module in the electronic device is controlled to turn on to trigger the heating module to provide second heat energy to the battery, and then step S416 is executed.
[0040] In step S416, (i.e., when the electronic device is in the second operating state and the temperature is not lower than the threshold), the heating module is controlled to shut down.
[0041] In summary, the electronic device and temperature control method of this application can utilize existing heat sources to raise or maintain the temperature of the battery, thereby avoiding the impact of low temperature environment on the performance of the electronic device.
