Preferably, the carrier board 30 in the hollow area 2011 is parallel or coplanar with the connection frame 201.

In this embodiment, the connecting frame 201 is mounted to the bottom of the accommodating space P101 through the sliding assembly 202, which can ensure that the connecting frame 201 slides smoothly and reliably between the first position and the second position. When the carrier board 30 is in the third position, it is located in the hollow area 2011 and is parallel or coplanar with the connecting frame 201, which can ensure that the carrier board 30 and the sliding frame 20 have a compact structure, a small footprint, and are convenient for use in the third position. The

electrical components

60a and 60b on the carrier board 30 are accommodated in the accommodating space P101.

Figures 1 and 9, Figure 10 show that in this example, it also includes a heat sink 60, which is provided on the cabinet 10 to dissipate heat for the

electrical components

60a, 60b in the accommodating space P101 In this way, using the heat sink 60 to actively dissipate the

electrical components

60a, 60b in the accommodating space P101 can improve the heat dissipation effect, ensure that the cabinet 10 maintains a proper ambient temperature, and ensure that the

electrical components

The first heat dissipating fan 601 is provided on the cabinet 10 for blowing air into the accommodating space P101; The second heat dissipation fan 602 is arranged on the cabinet 10 and away from the first heat dissipation fan 601, and is used for sucking the hot air in the accommodating space P101 and expelling it to the outside.

That is to say, the first heat dissipation fan 601 and the second heat dissipation fan 602 have opposite air outlet directions, and the first heat dissipation fan 601 has an air outlet direction toward the accommodating space P101 and can blow air into the accommodating space P101, while the second heat dissipation fan The air outlet direction of the fan 602 faces the outside of the accommodating space P101, and the hot air in the accommodating space P101 can be sucked and discharged to the outside of the cabinet 10. In this way, the inward blowing and outward exhausting methods can make the cabinet 10 Circulate air inside and outside to achieve the purpose of rapid heat dissipation and improve the heat dissipation effect.

Reach the purpose of refrigeration. Since the first heat dissipation fan 601 is configured such that the wind blown in passes through the cold surface of the semiconductor cooling fin 603, when the wind blown in by the first heat dissipation fan 601 passes through the cold surface of the semiconductor cooling fin 603, the temperature will be relatively high. Low cold air, the cold air then flows into the accommodating space P101, which can absorb the heat in the accommodating space P101 to form hot air. The hot air is further sucked by the second heat dissipation fan 602 and discharged out of the cabinet 10. In this way, Achieve better heat dissipation effect.

It should be noted that in order to save power, a temperature sensor and a controller can be configured to detect the temperature value in the accommodating space P101 through the temperature sensor. When the temperature value exceeds the threshold, the controller controls the semiconductor refrigeration sheet 603 to work, and uses semiconductor refrigeration. Sheet 603 realizes rapid heat dissipation. When the temperature value does not exceed the threshold, only the first heat dissipation fan 601 and the second heat dissipation fan 602 need to be controlled to work, and the first heat dissipation fan 601 and the second heat dissipation fan 602 can meet the heat dissipation requirement.

On top, and the ventilation space P102 is communicated with the accommodation space P101 by a connecting piece. In this way, the air blown by the first heat dissipation fan 601 enters the ventilation space P102, and passes through the cold surface of the semiconductor refrigeration fin 603 to cool down to form cold air , The cold air flows upwards into the accommodating space P101 through the connecting piece, absorbs the heat in the accommodating space P101, and then forms hot air. The hot air flow path is shown by the arrow in Figure 10. In this way, the independent air supply space P102 is used to cool the wind blown in by the first cooling fan 601, which can make the wind contact with the semiconductor cooling fins 603 sufficiently, and the resulting cold air temperature will be higher. Low, and ultimately, better heat dissipation effect can be achieved.
