The ventilation plate 105 and the heat plate 104 form an installation on the box 101. The wind force component is located in the installation groove and is fixed on the heat sink 104. When the wind force component is powered on and started, it can convert electrical energy into kinetic energy to rotate at high speed to generate wind force, thereby generating wind force inside the box body 101 through the heat sink 104, and sending outside air into the box body 101 with the cooperation of the ventilation plate 105, so as to realize the gas exchange between the inside and outside of the box body 101 and play a heat dissipation role for the inside of the box body 101.

At the same time, when the temperature inside the box 101 is high, the temperature sensor 108 transmits a signal that the temperature inside the box 101 is too high to the power supply box 107, so that the power supply box 107 supplies power to the fan 106, thereby starting the fan 106. The energized coil of the fan 106 rotates under the force in the magnetic field, so that the blades of the fan 106 rotate at a high speed, and then generate wind force, and the generated wind force is transmitted to the inside of the box 101 through the heat sink 104, thereby accelerating the air flow rate inside the box 101, so that the inside of the box 101 can be cooled, and the internal components of the box 101 are prevented from being damaged due to excessive temperature.

The setting of the handle 201 provides a force point for the operator, so that the operator can easily install and remove the ventilation plate 105 through the handle 201. The number of the magnetic plates 202 is twice the number of the metal frames 109, and every two of the magnetic plates 202 are connected to the ventilation plate 105. The force plate 202 is a group, which is respectively fixed on the upper and lower ends of the front side of the ventilation plate 105. The magnetic plate 202 is made of magnet material. After the ventilation plate 105 is inserted into the metal frame 109, the magnetic plate 202 abuts against the metal frame 109.
