The wind power adjusting module 45 is disposed on the circuit board 2 and connected to the fan 44, and the wind power adjusting module 45 is used for adjusting the wind power of the fan 44 according to the temperature in the shielding device.
As shown in fig. 2, the wind adjusting module 45 includes a temperature detecting unit 451, a control unit 452, and a motor control unit 453. The temperature detection unit 451 is used for detecting the temperature inside the shield and outputting a temperature signal; the control unit 452 is connected to the temperature detection unit 451 and receives the temperature signal to output an adjustment signal; the motor control unit 453 is connected to the control unit 452 and receives the adjustment signal. The fan 44 includes a motor 441, and a motor control unit 453 is connected to the motor 441 and adjusts the rotation speed of the motor 441 according to the adjustment signal.
Specifically, the temperature detecting unit 451 is a temperature sensor, the shielding module 3 generates more heat when the workload is large, the temperature in the shielding device increases accordingly, and the temperature detecting unit 451 can detect the temperature inside the shielding device in real time and output a temperature signal. The control Unit 452 may be a Micro Controller Unit (MCU), the control Unit 452 is connected to the temperature detection Unit 451, the temperature detection Unit 451 outputs a temperature signal to the control Unit 452, a temperature threshold is set on the control Unit 452, when the voltage of the temperature signal is lower than or equal to the temperature threshold voltage, the temperature inside the shielding device is within a normal range, the shielding module 3 is in normal load operation, and the fan 44 can meet the heat dissipation requirement only with a small wind force, so as to save energy; when the voltage of the temperature signal is higher than the temperature threshold voltage, the temperature in the shielding device exceeds the normal range, the shielding module 3 may work in an overload state, and then the control unit 452 outputs an adjusting signal to the motor control unit 453, and the motor control unit 453 adjusts the rotating speed of the motor 441, so that the wind power of the fan 44 is increased, and the efficient heat dissipation effect is achieved.

As shown in fig. 3, in the present embodiment, the heat dissipation plate 41 includes a first heat dissipation area 411 corresponding to the area where the shield module 3 is located and a second heat dissipation area 412 corresponding to the other area, and the heat dissipation fins 43 are divided into a first heat dissipation fin 431 provided at the first heat dissipation area 411 and a second heat dissipation fin 432 provided at the second heat dissipation area 412. The first and second heat dissipation fins 431 and 432 extend in the same direction, and the distance between the first heat dissipation fins 431 is smaller than the distance between the second heat dissipation fins 432. Since the shielding module 3 mainly works in the shielding device, the number of the first heat dissipation fins 431 on the first heat dissipation area 411 may be greater than the number of the second heat dissipation fins 432 on the second heat dissipation area 412, so that the heat dissipation efficiency of the shielding module 3 is improved, and the working stability of the shielding module 3 is improved. Further, the first heat sink 431 and the second heat sink 432 are disposed in an offset manner, and the fan 44 is disposed at an end of the casing 42 close to the second heat sink 432. Thus, when the fan 44 blows the air flow between the second heat dissipation fins 432 into the first heat dissipation fins 431, the air flow is divided into two parts by the first heat dissipation fins 431 and flows through the two sides of the first heat dissipation fins 431, so that the contact time between the air flow and the first heat dissipation fins 431 is increased, and the heat dissipation efficiency is further improved.
In addition, the width of the fan 44 is greater than the width of the second heat dissipation area 412, and the second heat dissipation fins 432 on the two side peripheries of the second heat dissipation area 412 extend outward from one end close to the fan 44 toward the fan 44. Specifically, the width of the fan 44 is larger than the width of the second heat dissipation area 412, so that a larger airflow can be generated to blow into the second heat dissipation area 412 for heat dissipation, and the heat dissipation effect is better. Further, the end surface of the second heat sink 432 near the end of the fan 44 is defined to form a concave surface, so that the airflow blown by the fan 44 can enter the second heat dissipation area 412 uniformly and synchronously, and the heat dissipation balance is improved.
As shown in fig. 1, in the present embodiment, the cover 42 further includes a base plate located at the bottom of the cover 42 and three-sided side plates disposed on the periphery of the base plate, and the three-sided side plates and the base plate constitute the cover 42; and the case 42 and the heat dissipation plate 41 define a heat dissipation space 6 having one side opened; wherein, a plurality of air inlets 421 are arranged on the side plate arranged on the back of the fan 44, and the air outlet direction of the fan 44 is opposite to the opening. Because inlet hole 421 and opening set up relatively, make the route that the air current passes through second radiating area 412 and first radiating area 411 shorten to the radiating efficiency has been improved, on the other hand because the heat dissipation capacity of first radiating area 411 is great, consequently with the setting that the opening is close to first radiating area 411, further shortened first radiating area 411 and sent out the external time with the heat, improved radiating efficiency.
