Example two
Corresponding to the above embodiment, the present application provides a regulating and controlling method for phase change, liquid cooling, and air cooling three-dimensional combined heat dissipation, as shown in fig. 4, the method includes the following steps:
step S1: and reading the first time temperature of the heat generating component, and executing the operation of the corresponding grade according to the first time temperature.
In a specific embodiment, the executing the operation of the corresponding grade according to the first time temperature specifically includes: when the temperature at the first moment is within a first-level threshold range, controlling the phase change heat dissipation part to work; when the temperature at the first moment is within the range of a secondary threshold value, controlling the phase change heat dissipation part and the liquid cooling heat dissipation part to work; and when the temperature at the first moment is within the range of the three-level threshold value, controlling the phase change heat dissipation part, the liquid cooling heat dissipation part and the air cooling heat dissipation fin to work.
In one specific embodiment, a primary threshold range of "1-15" is set, wherein the primary threshold range includes a "15" temperature point, a secondary threshold range of "15-25" includes a "25" temperature point, and a tertiary threshold range of "greater than 25" temperature. The temperature sensor is used for acquiring the temperature of the component at the first moment, and the controller is used for receiving the temperature at the first moment and controlling the corresponding heat dissipation process. When the temperature collected by the specific temperature sensor is 10 ℃, the temperature of the heating part at the moment corresponds to the range of the primary threshold value, the controller controls the phase-change heat dissipation part to start working, and the liquid cooling heat dissipation part and the air cooling heat dissipation fins do not work at the moment. When the temperature acquired by the temperature sensor is 20 ℃, and the temperature of the heating component corresponds to the range of the secondary threshold value, the controller controls the phase change heat dissipation part and the liquid cooling heat dissipation part to work simultaneously; when the temperature collected by the temperature sensor is 30 ℃, the temperature of the heating part corresponds to the three-level threshold range, and the controller controls the phase-change heat dissipation part, the liquid-cooling heat dissipation part and the air-cooling heat dissipation fins to work simultaneously so as to ensure that the temperature of the heating part is kept in a normal working range.
Step S2: and reading the temperature of the heat generating component at the second moment, and comparing the temperature at the second moment with the temperature at the first moment.
In a specific embodiment, when the absolute value of the difference between the second time temperature and the first time temperature is less than or equal to a preset threshold, the corresponding operation is not executed; and when the absolute value of the difference value between the second moment temperature and the first moment temperature is greater than a preset threshold value, executing operation.
In a specific embodiment, the preset threshold is set to be "5 ℃", for example, the temperature at the first time K is 5 ℃, the temperature at the second time (K + 1) is acquired to be "8 ℃", the difference between the temperatures at the first time K and the second time (K + 1) is calculated to be "3", at this time, the difference between the temperatures at the first time K and the second time (K + 1) is smaller than the preset threshold "5 ℃", and at this time, the corresponding operation is not executed; when the collected temperature at the second time (K + 1) is "18 ℃", calculating to obtain that the difference value between the temperatures at the first time K and the second time (K + 1) is "13", and at this time, the temperature difference value between the first time and the second time is greater than a preset threshold value "5 ℃", and executing corresponding operation.
And step S3: and if the second moment temperature is less than the first moment temperature, executing the operation of lowering the grade.
Specifically, the liquid cooling heat dissipation part and the phase change heat dissipation part work simultaneously at the first moment, and the reduced operation is to adjust the phase change heat dissipation part to perform heat dissipation work at the second moment; when the phase change heat dissipation part, the liquid cooling heat dissipation part and the air cooling heat dissipation fin work simultaneously at the first moment, the operation of the lower level is adjusted to be that the phase change heat dissipation part and the liquid cooling heat dissipation part work simultaneously at the second moment; and when the phase change heat dissipation part works at the first moment, the phase change heat dissipation part is not adjusted and continues to work.
Through the step S2, a relationship between a difference between the second time temperature and the first time temperature and a preset threshold is specifically determined, and when the preset threshold is "6" and the first time temperature is "20 ℃", the corresponding operation is that the phase change heat dissipation part and the liquid cooling heat dissipation part work simultaneously; acquiring the temperature of 10 ℃ at the second moment, wherein the temperature at the second moment is lower than the temperature at the first moment, and executing the grade reduction operation that the liquid cooling heat dissipation part is closed and the phase change heat dissipation part only works; if the temperature at the second moment is acquired at the moment and is 18 ℃, the absolute value of the difference between the temperature at the second moment and the temperature at the first moment is 2, and the absolute value of the difference is smaller than a preset threshold value 6, the corresponding operation is not executed at the moment, and the state that the current phase-change heat dissipation part and the current liquid-cooling heat dissipation part work simultaneously is still maintained.
And step S4: and if the temperature at the second moment is greater than or equal to the temperature at the first moment, continuing to execute the current operation and increasing to execute the operation at a higher level.
In a specific embodiment, according to the method in step S3, it can be known that, when the phase-change heat dissipation part is operated at the first time, the higher-level operation is performed to adjust the liquid-cooled heat dissipation part to operate, and at the same time, the phase-change heat dissipation part is kept to operate; when the corresponding operation at the first moment is that the liquid cooling heat dissipation part and the phase change heat dissipation part work, executing higher-level operation to adjust the air cooling heat dissipation fins to perform heat dissipation work, and simultaneously keeping the liquid cooling heat dissipation part and the phase change heat dissipation part also work; when the operation corresponding to the first moment is that the air-cooled heat dissipation part, the liquid-cooled heat dissipation part and the phase-change heat dissipation part all work, and the temperature at the second moment is greater than or equal to the temperature at the first moment, other operations are not performed.
In a specific embodiment, a preset threshold is set to be "5", the temperature at the first moment is "6 ℃", the corresponding operation at the first moment is that the phase-change heat dissipation part performs heat dissipation independently, the temperature at the second moment is collected to be "10 ℃", and because the absolute value of the temperature difference between the temperature at the second moment and the temperature at the first moment is smaller than the preset threshold, no other operation is performed; the temperature of the second time is collected to be 15 ℃, and the temperature difference between the second time and the first time is larger than a preset threshold value, so that the liquid cooling heat dissipation part and the phase change heat dissipation part are adjusted to work in a combined manner at the second time.
In a specific embodiment, the preset threshold is set to be "5", the temperature at the first moment is "28 ℃", the corresponding operation at the first moment is that the air-cooled heat dissipation fin, the liquid-cooled heat dissipation part and the phase-change heat dissipation part work simultaneously, the temperature at the second moment is collected to be "30 ℃", and as the operation at the first moment is the highest-level operation, the current heat dissipation working state is continuously maintained at this moment, and higher-level adjustment is not performed.
