[0039] DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0041] During use of a notebook computer, excessive load can cause overloading operation of hardware components such as CPU, GPU, and display card, thereby causing heating problems. Meanwhile, long-time use of the notebook computer can also cause internal temperature rise and heating. Since temperature rise of the notebook computer can cause poor user experience of using the notebook computer, the notebook computer is usually cooled to ensure normal operation of the notebook computer.

[0042] In feasible embodiments of the present application, the notebook heat sink is used to blow heat away from the bottom of the notebook computer, forcibly blow heat out of the notebook computer, and introduce cold air to increase air flow at the bottom of the notebook computer, so that each heating element in the notebook computer is cooled.

[0043] In the embodiments of the present application, the structure of the notebook heat sink can refer to Fig. 1, which is a three-dimensional schematic diagram of the notebook heat sink in an embodiment of the present application. The notebook heat sink includes a main body shell 1, a heat dissipation fan 2, a sponge gasket 3, a fan control part 4, and a control circuit board 5. The control circuit board 5 is arranged in the main body shell 1, the fan control part 4 is partially arranged in the main body shell 1 and partially exposed on the surface of the main body shell 1. An air outlet groove 6 is formed on one side of the main body shell 1, and an air inlet 7 is formed on the other side. The heat dissipation fan 2 is partially arranged in the main body shell 1 and partially arranged in the air outlet groove 6. The sponge gasket 3 is arranged around the air outlet groove 6. The fan control part 4 and the heat dissipation fan 2 are electrically connected to the control circuit board 5.

[0044] When the notebook radiator is powered on, the user places the notebook computer on the sponge pad 3 so that the notebook computer covers the opening of the air outlet groove 6, and the opening and air outlet speed of the cooling fan 2 can be controlled through the fan control part 4, the cooling fan 2 brings the air at the air inlet 7 to the air outlet groove 6 and blows to the inside of the notebook computer, the sponge pad 3 fills the gap between the air outlet groove 6 and the notebook computer, so that more air blown by the cooling fan 2 can blow into the notebook computer, and the cooling efficiency is improved.

[0045] At present, most of the notebook cooling devices are manually controlled temperature, when the notebook temperature is found to be increased, the notebook is cooled by manually controlling the cooling device. The manual control method cannot accurately determine the current temperature of the notebook, and cannot accurately position the speed to be adjusted, thereby causing poor cooling effect.

[0046] Therefore, in order to accurately and efficiently cool the notebook, in the embodiment of the present application, a cooling method is provided, please refer to Fig. 2, which is a flowchart of the cooling method in the embodiment of the present application, the cooling method is applied to a radiator, the radiator includes a fan, the speed of the fan is controlled according to the current temperature of the radiator to cool the notebook, and the cooling method specifically includes:

[0047] Step 110, the current temperature of the object to be cooled is acquired in real time, and a cooling mode selected by a user is acquired.

[0048] In the embodiment of the present application, the object to be cooled can be hardware in the notebook that needs to be cooled, for example, can be GPU, CPU and the like.

[0049] The temperature monitoring of the object to be cooled can be realized by a device capable of monitoring temperature, a device for detecting the temperature of the GPU or CPU of the notebook can be selected to be installed on the notebook, or a temperature measuring software can be installed on the notebook, the temperature measuring software can be directly input into the bottom layer of windows to acquire the temperature, or the temperature of the computer can be acquired in real time by reading the data of the measurement and control software such as Luda, and the way of acquiring the temperature is not limited. The temperature measuring device or the temperature measuring software is connected with the radiator through an electrical signal, and the detected temperature is sent to the radiator, so as to achieve the purpose of monitoring the temperature of the object to be cooled in real time.

[0050] Secondly, the embodiment of the present application provides a plurality of cooling modes, and the cooling speed of different cooling modes is different, and the user can select according to the cooling demand.

[0051] Step 120, the current temperature of the object to be cooled and the cooling mode are analyzed to determine the target speed of the fan of the radiator.

[0052] After the current temperature of the object to be cooled and the cooling mode selected by the user are obtained through step 110, the current temperature and the cooling mode are analyzed, the speed required for the fan of the cooler to reach if the temperature of the object to be cooled needs to be reduced to the normal temperature range is determined, and the speed is taken as the target speed.

[0053] Step 130, the fan is controlled to move at the target speed to cool the object to be cooled.

[0054] After the target speed is obtained, the fan of the cooler is controlled to move at the target speed to cool the object to be cooled.

[0055] The embodiment of the present application considers the cooling demand of the user on one hand, and monitors the temperature of the object to be cooled in time on the other hand, analyzes the cooling demand of the user and the temperature of the object to be cooled, and realizes real-time adjustment of the speed of the fan of the cooler, so as to achieve high-efficiency cooling effect.

[0056] In step 120 of the embodiment of the present application, the current temperature of the object to be cooled and the cooling mode are analyzed to determine the target speed of the fan of the cooler, and specifically include:

[0057] Step 121, the preset total temperature range is divided into multiple temperature intervals according to a preset division standard.

[0058] In an embodiment of the present application, a temperature interval and a total temperature range can be preset, the total temperature range is divided into multiple intervals according to the temperature interval as the division standard, and the total temperature range is divided into multiple intervals. For example, the temperature interval can be set to 10℃, the total temperature range can be set to 0℃-100℃, and then the total temperature range can be divided into 10 temperature intervals, such as [0℃-10℃), [10℃-20℃), [20℃-30℃), …, [80℃-90℃), [90℃-100℃].

[0059] It can be understood that the smaller the temperature interval is divided, the more temperature intervals are divided, and the more accurate the speed adjustment result based on the temperature interval is, and then the cooling effect is better.

[0060] Step 122, the current temperature of the object to be cooled is compared with each temperature interval to determine the target temperature interval in which the current temperature of the object to be cooled is located.

[0061] Specifically, the current temperature of the object to be cooled obtained in step 110 is compared and analyzed with the temperature intervals divided in step 121 to find in which temperature interval the current temperature of the object to be cooled falls. For example, if the temperature intervals include ten, namely [0℃-10℃), [10℃-20℃), [20℃-30℃), …, [80℃-90℃), [90℃-100℃], and the current temperature of the object to be cooled is 44℃, then the current temperature of the object to be cooled is in the temperature interval of [30℃-40℃), which is taken as the target temperature interval.

[0062] Step 123, analyzing the target temperature interval and the cooling mode to determine the target rotating speed of the fan of the heat sink.

[0063] In an embodiment of the present application, the cooling mode is at least two and more than two, and the cooling speed, energy consumption and noise size of different cooling modes are different. Step 123, analyzing the target temperature interval and the cooling mode to determine the target rotating speed of the fan of the heat sink, specifically including:

[0064] Step 1231, obtaining a temperature-rotating speed table, the temperature-rotating speed table including the rotating speed corresponding to the target cooling mode in different temperature intervals, the target cooling mode being any one of all cooling modes.

[0065] In an embodiment of the present application, the cooling mode can include a breeze mode, a gale mode and a hurricane mode. It can be understood that the cooling speed of the breeze mode is relatively slow, the cooling speed of the hurricane mode is relatively fast, and the cooling speed of the gale mode is between the cooling speed of the breeze mode and the cooling speed of the hurricane mode.

[0066] In an embodiment of the present application, the total temperature range can be determined as 0℃-100℃, and the total temperature range is divided into eight temperature intervals, namely [0℃-30℃], [31℃-40℃], [41℃-50℃], [51℃-60℃], [61℃-70℃], [71℃-80℃], [81℃-90℃] and [91℃-100℃]. Based on this, the temperature-rotating speed table can refer to Table 1, which is the temperature-rotating speed table in the embodiment of the present application. The temperature-rotating speed table in this embodiment includes the rotating speed corresponding to each temperature interval in the breeze mode, the gale mode and the hurricane mode.

[0067] Table 1 Temperature-rotating speed table

[0068] Mode / Temperature 0℃-30℃ 31℃-40℃ 41℃-50℃ 51℃-60℃ 61℃-70℃ 71℃-80℃ 81℃-90℃ 91℃-100℃ Clear mode 300rpm 400rpm 500rpm 600rpm 700rpm 800rpm 900rpm 1000rpm Gale mode 600rpm 800rpm 1000rpm 1200rpm 1400rpm 1600rpm 1800rpm 2000rpm Hurricane mode 1000rpm 1200rpm 1400rpm 1600rpm 1800rpm 2000rpm 2200rpm 2400rpm

[0069] Step 1232, analyze according to the target temperature interval, the cooling mode and the temperature speed table, and obtain the target speed of the fan of the radiator.

[0070] Specifically, after obtaining the temperature speed table, the target speed corresponding to the target temperature interval in the temperature speed table under the cooling mode selected by the user is found, so that the fan of the radiator is controlled to move at the target speed.

[0071] The embodiment of the present application realizes efficient cooling by monitoring the temperature of the object to be cooled in real time, changing the speed of the fan of the radiator when the temperature of the object to be cooled reaches the threshold of a certain temperature interval, and adjusting the speed of the fan of the radiator based on the current temperature of the object to be cooled.

[0072] In the embodiment of the present application, the cooling mode can also include a custom cooling mode, so that step 123, analyzing according to the target temperature interval and the cooling mode, determines the target speed of the fan of the radiator, specifically including:

[0073] A, after the user selects the custom cooling mode, the cooling adjustment parameter and the parameter speed curve of the user are obtained, and the parameter speed curve contains the linear relationship between the cooling adjustment parameter and the speed.

[0074] The custom cooling mode can be manual adjustment of the speed of the fan of the radiator by the user, or the speed of the fan of the radiator can be determined after analyzing the cooling demand of the user.

[0075] Specifically, after obtaining that the cooling mode selected by the user is the customized cooling mode, the cooling demand of the user is obtained. The cooling demand includes various parameter types, and the parameter types can include sound, speed, energy saving, etc. The user adjusts according to the requirement of each parameter type, and generates a cooling adjustment parameter. For example, each parameter type can set an adjustment range for the user to adjust, such as providing an adjustment gear of 0-100 for the user to select, and the gear selected by the user is the cooling adjustment parameter. Therefore, the cooling adjustment parameter can at least include one or a combination of the noise adjustment parameter, the speed adjustment parameter and the energy saving adjustment parameter. When the user is sensitive to noise and wants to maintain a quiet environment, a lower gear can be selected in the adjustment range; if the user wants to cool quickly, a higher gear can be selected in the adjustment range; if the user wants to save energy, a lower gear can be selected in the adjustment range.

[0076] In the embodiment of the application, through multiple experimental analysis and calculation, a linear fitting curve between the gear of each parameter type and the speed, i.e., a parameter speed curve, is obtained. The parameter speed curve at least includes a noise speed curve, a speed speed curve, an energy saving speed curve, etc.

[0077] B. According to the cooling adjustment parameter of the user and the parameter speed curve, calculation and analysis are performed to obtain the target speed of the fan of the radiator.

[0078] Specifically, according to the cooling adjustment parameter selected by the user and the parameter speed curve, the speed corresponding to each parameter type is obtained. For example, the noise adjustment parameter is calculated with the noise speed curve to obtain the first speed corresponding to the noise parameter type; the speed adjustment parameter is calculated with the speed speed curve to obtain the second speed corresponding to the speed parameter type; and the energy saving adjustment parameter is calculated with the energy saving speed curve to obtain the third speed corresponding to the energy saving parameter type.

[0079] After obtaining the speed corresponding to each parameter type, the target speed of the fan of the radiator is obtained based on the speed corresponding to each parameter type and the weight of each parameter set in advance.

[0080] The embodiment of the application considers the cooling demand of different users, performs personalized setting of the user, obtains the cooling demand suitable for different users, and achieves better cooling effect.

[0081] In an embodiment of the application, when the cooling mode selected by the user is not obtained, the default cooling mode set in advance is taken as the cooling mode selected by the user.

[0082] Specifically, in consideration of the fact that the user may forget to select the cooling mode, resulting in failure to perform cooling heat dissipation, in order not to affect the normal operation of the heat dissipation device, a default cooling mode is set in advance, the default cooling mode is taken as the cooling mode selected by the user, and then the object to be cooled is cooled.

[0083] In an embodiment of the present application, the heat dissipation device comprises a storage module, which is used to store the cooling mode selected by the user each time; then the default cooling mode can be the cooling mode selected by the user last time.

[0084] Specifically, the storage module has a memory function, after the user selects the cooling mode each time, the cooling mode selected this time is stored, and when the user does not select the cooling mode next time, the cooling mode selected by the user last time is taken as the cooling mode next time.

[0085] An embodiment of the present application provides a heat dissipation device, please refer to Fig. 3, which is a structural block diagram of the heat dissipation device of the embodiment of the present application, and the device comprises a signal receiving module 301, a rotating speed analysis module 302 and a heat dissipation module 303.

[0086] The signal receiving module 301 is used to acquire the current temperature of the object to be cooled and the cooling mode selected by the user in real time.

[0087] The rotating speed analysis module 302 is used to analyze the current temperature of the object to be cooled and the cooling mode, and determine the target rotating speed of the fan of the heat dissipation device.

[0088] The heat dissipation module 303 is used to control the fan to move at the target rotating speed, so as to perform heat dissipation on the object to be cooled.

[0089] The heat dissipation device provided by the embodiment of the present application can monitor the temperature of the object to be cooled in real time, select the appropriate rotating speed of the fan according to the temperature of the object to be cooled, and adjust the rotating speed of the fan of the heat dissipation device in real time based on the current temperature, so as to realize timely and efficient heat dissipation.
