As shown in fig. 8, the heat dissipation system 10 according to an embodiment of the present application performs operation control according to the following steps:
step S100: acquiring the temperature of a heat pipe of a heat dissipation heat pipe;
step S102: judging whether the temperature of the heat pipe is not less than a temperature threshold value or not, and generating a first judgment result;
step S104: if the first judgment result is yes, determining a rotating speed gear corresponding to the rotating speed of the fan before the lifting;
step S106: the rotating speed gear is lifted, and the fan is controlled to operate according to the rotating speed corresponding to the lifted rotating speed gear;

step S120: and when the output frequency is the lowest frequency threshold value, if the temperature of the heat pipe is not less than the temperature threshold value, controlling the compressor to stop running and sending fault prompt information.
In the embodiment, the temperature of the heat pipe of the heat dissipation heat pipe is obtained through the temperature sensor and fed back to the microcontroller, so that the rotating speed of the fan is controlled through the microcontroller; specifically, when the temperature of the heat pipe is not less than the temperature threshold, the temperature is too high, so that the working medium in the heat radiating heat pipe can be boiled and gasified, and whether the fan is located at the highest gear or not and the number of gears which can be lifted by the fan can be determined by determining the gear of the rotating speed corresponding to the rotating speed of the fan before lifting; for example, the fan can be lifted from 1 gear to 2 gears, namely, the fan can be lifted step by step, also can be lifted from 1 gear to 3 gears directly, namely, the fan can be adjusted by jumping gears, and also can be adjusted in a stepless speed regulation mode, namely, no specific gear exists, the wind speed is changed continuously, and the wind speed is not directly jumped from one speed to another speed; the air flow is further accelerated by increasing the wind speed, the air flow around the heat dissipation heat pipe is accelerated, and the heat dissipation efficiency is improved; furthermore, the fan increases the rotating speed of the fan at intervals of a first time interval, so that the air flow can be gradually accelerated, namely the heat dissipation effect of the fan on the heat dissipation heat pipe is gradually increased, the heat dissipation efficiency near the heat dissipation heat pipe is further accelerated, and the phenomenon that the working medium in the heat dissipation heat pipe is boiled and gasified due to overhigh temperature is avoided; along with the gear of the fan is increased and the heat dissipation heat pipes continuously dissipate heat, the temperature of the heat pipes can be gradually reduced, and after the temperature of the heat pipes is smaller than a temperature threshold value, the fan is not required to be continuously accelerated, so that the adjustment of the rotating speed of the fan can be stopped, the power consumption is reduced, and the energy is saved.
In the control process, the microcontroller is connected with the temperature sensor and the fan, so that the rotating speed of the fan can be intelligently adjusted along with the change of the temperature of the heat pipe, the heat dissipation heat pipe is effectively protected, and the service life of the heat dissipation heat pipe is prolonged.
Furthermore, with the continuous rise of the temperature of the heat pipes of the heat dissipation heat pipes, the rotating speed of the fan may rise to the limit rotating speed, and the temperature of the heat pipes is still not less than the temperature threshold value, which indicates that the heat dissipation heat pipes cannot be cooled by the fan at this time, and the output power of the compressor is adjusted to reduce the power consumption and reduce the heat productivity of the product, so that the heat dissipation workload of the heat dissipation heat pipes is reduced, the temperature of the heat pipes is reduced, the heat dissipation heat pipes are prevented from being too high, the heat dissipation heat pipes are protected, the service life of the heat dissipation heat pipes is prolonged, and the stability and the reliability of the product; furthermore, when the output frequency is the lowest frequency threshold, if the temperature of the heat pipe is not less than the temperature threshold, it indicates that the heat pipe is still at a high temperature under the condition that the calorific value of the product is very low, and generally a fault occurs, so that the operation of the compressor is stopped, and a fault prompt message is sent out to avoid generating a larger problem, and avoid generating a condition that the temperature of the heat pipe is too high, so as to form effective protection for the heat pipe.
It will be appreciated that in order to connect the blower to the microcontroller, a signal receiver may also be provided in the blower to communicate with the microcontroller and enable the microcontroller to control the speed of the blower via the signal receiver.
According to the heat dissipation system 10 of another embodiment of the present application, the heat dissipation heat pipe 100 can be protected; by integrally controlling the heat dissipation system 10, a good heat dissipation effect can be achieved on the frequency conversion module 12, and meanwhile, the heat dissipation heat pipe 100 is protected from the situation that the heat dissipation effect is reduced or even the service life of the heat dissipation heat pipe 100 is reduced due to overhigh temperature.
Specifically, the heat dissipation system 10 of the present application adds a temperature sensor 106 to the heat dissipation device of the heat dissipation heat pipe 100 to measure the heat pipe temperature TR; and the temperature sensor 106 is disposed on an insulated section of the pipe.
As shown in fig. 9, the control steps of the present embodiment are as follows:
step S200: the system normally operates;
step S202: detecting whether the temperature TR of the heat pipe is larger than a temperature threshold TF 1;
step S204: if so, judging whether the wind level is the highest;
step S206: when the wind shield is not the highest, the wind shield rises by one shield;
step S208: when the wind gear is the highest, judging whether the frequency of the compressor is the lowest;
step S210: if not, the compressor frequency is decreased aHZ;
step S212: if yes, the system is shut down, and system failure is prompted.
When the temperature TR of the heat pipe is detected to exceed the threshold TF1, the rotating speed of the fan is preferentially increased to enhance the heat dissipation effect; when the increase of the rotating speed of the fan can not reduce the temperature of the heat pipe to be lower than TF1, the output frequency of the compressor is started to be reduced until the temperature is reduced to be lower than TF 1.
Wherein, the threshold TF1 is a protection temperature close to the boiling and gasification temperature of the working medium in the heat-radiating heat pipe.
The main control principles of the heat dissipation system 10 of the present application are as follows:
1) detecting the temperature TR of the heat pipe after the system starts to operate;
2) if TR is less than or equal to TF1, normally controlling a system compressor and a fan;
3) if TR is greater than TF1, increasing the first-gear rotating speed of a system fan, and if TR cannot be reduced to TF1, increasing the windshield by one gear at intervals of t1 (namely a first time interval) until the windshield is increased to the highest;
4) when the windshield rises to the maximum, TR still cannot be reduced to TF1, and the compressor output frequency starts to be reduced, wherein the TR is reduced by aHZ every time interval t2 (namely, the second time interval);
5) when TR is reduced to TF1, the system frequency and windshield resume normal control.
The temperature sensor, the microcontroller, the fan, the compressor and other parts in the heat dissipation system are connected, the control logic can be realized, the heat dissipation system can be integrally controlled, a good heat dissipation effect can be achieved on the frequency conversion module, meanwhile, the heat dissipation heat pipe is protected from being too high in temperature, the working medium inside the heat dissipation heat pipe is boiled and gasified, the heat dissipation effect is reduced, and even the service life of the heat dissipation heat pipe is reduced.
Above combine the figure to describe in detail the technical scheme of the utility model, through the utility model discloses a technical scheme has set up temperature sensor at the adiabatic section of heat dissipation heat pipe and has detected the heat pipe temperature, has still set up microcontroller and temperature sensor and has connected, and according to heat pipe temperature control fan rotational speed, perhaps the output of adjustment compressor is less than the temperature threshold value until the heat pipe temperature, such cooling system can provide effective protection for the heat dissipation heat pipe, avoid heat dissipation heat pipe high temperature, make its inside working medium boiling gasification and lead to the radiating effect seriously to descend, the life of heat dissipation heat pipe has still been promoted.
