[0079] Specifically, the specific steps of step S2 include:

[0080] S2.1: Use the regression analysis method to construct a temperature model, and define the working temperature of the wind direction predictor as the dependent variable of the model; since the working temperature is affected by various environmental factors, for example, high humidity will increase the heat load of the wind direction predictor and thus cause the working temperature to rise, and low air pressure results in low air density and reduced heat dissipation ability, leading to an increase in the working temperature. Therefore, define each environmental parameter as an independent variable of the model, such as environmental temperature, humidity, wind speed, wind direction, and air pressure; the expression of the objective function of the model is as follows:

[0098] S2.10: Obtain the converged parameter group , substitute the parameter group into the temperature model. At this time, the training of the temperature model is completed, and the temperature model is output for subsequent prediction.

[0099] Specifically, the specific steps of step S3 include:

[0100] S3.1: Read the environmental parameter data in the parameter database and construct the environmental parameter matrix ; where is the number of collected samples.

In this embodiment, the heat dissipation device is a liquid cooling heat dissipation device. When the wind direction predictor works, the generated heat is transferred to the liquid cooling pipe through the radiator, and the heat is absorbed through the circulating flow of the coolant. Set the initial flow rate of the coolant to be constant, which is ;
