All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the application provides a cooling method which can be applied to a microcontroller and used for controlling and reducing the temperature of a bearing controller.
A cooling method provided in the embodiments of the present application will be described in detail below with reference to specific embodiments, as shown in fig. 1, the specific steps are as follows:
step 101: the current temperature of the bearing controller is obtained.
In the embodiment of the application, a bearing controller of the magnetic suspension water chilling unit generates a large amount of heat in the working process, and in order to reduce the temperature of the bearing controller, the microcontroller needs to acquire the current temperature of the bearing controller.
The specific process can be as follows: a temperature sensor is arranged beside a bearing controller and used for detecting the temperature of the bearing controller, and a microcontroller acquires sampling signals of the temperature sensor through an ADC (analog to digital converter) sampling module and then judges whether the sampling signals are zero or not. If the microcontroller judges that the sampling signal is zero, indicating that the temperature sensor has a fault, sending a fault alarm; if the microcontroller judges that the sampling signal is not zero, the temperature sensing is normal, and the microcontroller calculates the acquired temperature.
Step 102: and under the condition that the current temperature does not accord with the preset temperature condition, selecting a target control valve from the plurality of control valves according to the current temperature.
The cooling media controlled by any two control valves in the plurality of control valves are different, and the target control valve is one or more.
In this embodiment of the present application, after the microcontroller calculates the collected temperature, if it is determined that the current temperature of the bearing controller does not meet the preset temperature condition, the microcontroller is required to select a target control valve from the plurality of control valves according to the current temperature, where the target control valve is used to control input of a cooling medium into the bearing controller, and the cooling media controlled by any two control valves in the plurality of control valves are different. The target control valve may be one or more, and if the target control valve is plural, the target control valve may control plural kinds of cooling media.
The cooling medium comprises a first cooling medium and a second cooling medium, and the cooling amplitude of the first cooling medium in unit time is smaller than that of the second cooling medium in unit time. For example, the first cooling medium may be cooling water, and the second cooling medium may be a cooling medium, wherein the cooling water is a cooling medium other than the cooling medium.
Illustratively, the target control valves include three types, one type being a first control valve using cooling water and a second control valve using a cooling medium, and the last type being a second control valve using a cooling medium.
Step 103: and controlling the input of a cooling medium to a radiating plate of the bearing controller through a target control valve so as to reduce the temperature of the bearing controller.
In this embodiment, after the microcontroller selects the target control valve, the target control valve controls the input of the cooling medium to the heat dissipation plate of the bearing controller, so as to reduce the temperature of the bearing controller through the cooling medium.
After the microcontroller samples the temperature of the bearing controller after reduction, if the temperature after reduction is judged to be not in accordance with the preset temperature condition, the target control valve is selected again according to the temperature after reduction, the temperature of the bearing controller is reduced through a cooling medium in the target control valve, and the process is repeated until the temperature of the bearing controller is in accordance with the preset temperature condition.
Different target control valves can be selected according to the current temperature, different cooling media are adopted to reduce the temperature of the bearing controller in sequence, the cooling process of the bearing controller is stable and slow, the temperature of the bearing controller is gradually close to the ambient temperature, the phenomenon that the temperature of the bearing controller is different from the ambient temperature to generate condensate water greatly is avoided, and the safety of the bearing controller in the cooling process is improved.
The vapor in the air can condense into the comdenstion water and get into the bearing controller after meeting cold, makes the bearing controller have the short circuit risk, consequently should do sealed work to the bearing controller in advance, but need external debugging line when debugging the bearing controller, can't compromise the debugging and the sealed of bearing controller simultaneously. By adopting the scheme of the application, condensate water can not be generated, the bearing controller can be debugged in an open state, the normal operation of debugging work is ensured, and the test efficiency is improved.

In the embodiment of the application, the microcontroller calculates the absolute value of the difference between the current temperature and the target temperature, then the opening degree of the target control valve is adjusted according to the absolute value, the absolute value and the opening degree of the target control valve are in a direct proportion or inverse proportion relation, the adjustment of the opening degree of the target control valve can change the flow of the cooling medium passing through the bearing controller in unit time, in order to avoid the condition that the temperature of the bearing controller is too low to generate condensed water, the flow of the cooling medium passing through the bearing controller in unit time is reduced, and therefore the cooling speed of the bearing controller is reduced.
As an alternative embodiment, the selecting a target control valve from the plurality of control valves according to the current temperature includes: in the case where the current temperature is not greater than the first temperature threshold, a first control valve for controlling the input of the first cooling medium into the bearing controller is selected from the plurality of control valves.
In the embodiment of the application, after the microcontroller obtains the current temperature of the bearing controller, if the current temperature is determined to be not greater than the first temperature threshold, the first control valve for controlling the input of the first cooling medium into the bearing controller is selected from the plurality of control valves, wherein the first temperature threshold is the smallest value among the plurality of temperature thresholds.
Illustratively, there are three temperature thresholds, T1、T2、T3Wherein, T1<T2<T3. The current temperature of the bearing controller is Ta，T1Can be regarded as the ambient temperature, if Ta≤T1Indicating that the current temperature is not greater than ambient temperature to avoid condensationWater, cooling water may be used to increase the temperature of the bearing controller.
As an alternative embodiment, when the first control valve is selected, adjusting the opening degree of the target control valve according to the magnitude of the absolute value includes: and adjusting the opening degree of the first control valve according to the magnitude of the absolute value, wherein the magnitude of the absolute value is in negative correlation with the opening degree of the first control valve.

The larger the absolute value is, the larger the difference between the current temperature and the first temperature threshold is, the current temperature is lower than the normal temperature, in order to enable the temperature of the bearing controller to be close to the normal temperature, the unit time flow rate of the first cooling medium can be reduced, and the normal temperature can be reached by adopting a small amount of the first cooling medium for heating.
Illustratively, the absolute value of the difference between the current temperature and the target temperature is | Ta-T1|，|Ta-T1The larger the value of | is, the smaller the opening degree of the first control valve is.
As an alternative embodiment, the selecting a target control valve from the plurality of control valves according to the current temperature includes: and under the condition that the current temperature is greater than the first temperature threshold and not greater than the second temperature threshold, selecting a first control valve for controlling the input of a first cooling medium into the bearing controller and a second control valve for controlling the input of a second cooling medium into the bearing controller from the plurality of control valves, wherein the temperature reduction amplitude of the first cooling medium in unit time is smaller than that of the second cooling medium in unit time.
In this embodiment, after the microcontroller obtains the current temperature of the bearing controller, if it is determined that the current temperature is greater than the first temperature threshold and not greater than the second temperature threshold, a first control valve for controlling input of a first cooling medium into the bearing controller and a second control valve for controlling input of a second cooling medium are selected from the plurality of control valves, where the second temperature threshold is higher than the first temperature threshold, and a temperature decrease range of the first cooling medium per unit time is smaller than a temperature decrease range of the second cooling medium per unit time.
Illustratively, there are three temperature thresholds, T1、T2、T3Wherein, T1<T2<T3. The current temperature is TaIf T is2≥Ta>T1The temperature of the bearing controller is higher than the normal temperature, the cooling effect on the bearing controller cannot be achieved only by adopting cooling water, and then the bearing controller can be cooled by adopting the cooling water and a cooling medium at the same time.
As an alternative embodiment, when the first control valve and the second control valve are selected, adjusting the opening degree of the target control valve according to the magnitude of the absolute value includes: controlling the first control valve to be at the maximum opening degree; and adjusting the opening degree of the second control valve according to the magnitude of the absolute value, wherein the magnitude of the absolute value is positively correlated with the opening degree of the second control valve.
In this embodiment, when the first control valve and the second control valve are selected, it indicates that the current temperature of the bearing controller is higher than the normal temperature, so the microcontroller can control the first control valve to be the maximum opening, and since the cooling speed of the second cooling medium per unit time is greater than that of the first cooling medium, the opening of the second control valve can be adjusted, and the temperature of the bearing controller is adjusted through the second cooling medium.
The microcontroller adjusts the opening degree of the second control valve according to the magnitude of the absolute value, the magnitude of the absolute value is in positive correlation with the opening degree of the second control valve, and the larger the absolute value is, the larger the opening degree of the second control valve is. The larger the absolute value is, the larger the difference between the current temperature and the first temperature threshold is, the larger the difference between the current temperature and the normal temperature is, the larger the opening degree of the second control valve can be increased by the bearing controller, the flow of the second cooling medium in unit time is increased, and the cooling speed is accelerated.
As an alternative embodiment, when selecting the second control valve, selecting the target control valve from the plurality of control valves according to the current temperature includes: and selecting a second control valve for controlling the input of the second cooling medium into the bearing controller from the plurality of control valves when the current temperature is greater than the second temperature threshold and not greater than the third temperature threshold.

The larger the absolute value is, the larger the difference between the current temperature and the first temperature threshold is, the larger the difference between the current temperature and the normal temperature is, the higher the temperature of the bearing controller is compared with the normal temperature, the unit time flow of the second cooling medium can be increased, and the second cooling medium is adopted for cooling to improve the cooling speed.
