Then it is discharged through the exhaust port on the top of the cabinet. The cooperation of the exhaust fan and the intake fan can realize the convection of the air and increase the heat dissipation effect.

Preferably, the cabinet is provided with an air intake filter screen for filtering at the position of the air inlet. The air intake filter realizes the filtration of the air, preventing the outside dust from entering the cabinet and destroying the electronic components.

Preferably, two air intake fans are symmetrically arranged on the left and right sides of the air exhaust duct.

Preferably, there are three partitions located on the left and right sides of the exhaust duct, respectively.

Preferably, a chute is provided at the upper part of the partition plate, and the partition plate is slidably connected to the placing plate through the chute. Through the push-pull placement, the equipment can be quickly installed, repaired and replaced.

Preferably, a controller is provided on the upper right side of the cabinet, and the controller is electrically connected to the exhaust fan and the intake fan respectively.

Advantages of the present invention:

1. The outside air is drawn into the air inlet through the air inlet by the air inlet fan, enters the air inlet duct, and then is discharged into the cabinet through the air inlet on the outer wall of the air inlet duct, and then the hot air inside the cabinet passes through the side wall of the exhaust duct. The ventilation hole is then discharged through the exhaust port on the top of the cabinet. The cooperation of the exhaust fan and the intake fan can achieve air convection and increase the heat dissipation effect.

2. Through the push-pull structure placement plate, the equipment can be quickly installed, repaired and replaced.

3. The air inlet filter is installed at the position of the air inlet, which can filter the air and prevent the external dust from entering the cabinet and destroying the electronic components.

Detailed ways

In order to make the technical means, creative features, achievement goals and effects realized by the present invention easy to understand, the present invention will be further described below with reference to the specific embodiments.

As shown in Figure 1-2, a cooling network cabinet includes a cabinet body 1, a cabinet door 2 on the front side of the cabinet body 1, and a roller 3 at the bottom of the cabinet body 1. The middle of the inner cavity of the cabinet body 1 is provided with a row The air duct 4, the left and right side walls of the air exhaust duct 4 are provided with a number of through holes, the inner cavity of the air exhaust duct 4 is provided with an exhaust fan 5, and the upper part of the cabinet 1 is provided with a connection with the exhaust duct 4. The air outlet 6, the inner cavity of the cabinet body 1 is provided with partitions 7 at equal intervals on the left and right sides of the air exhaust duct 4, the inner cavity of the cabinet body 1 and the bottom position of the air exhaust duct 4 are provided with fixed plates 8, An air intake fan 9 is arranged at the bottom of the inner cavity of the cabinet body 1 , and an air intake pipe 10 is connected to the air outlet of the air intake fan 9 . The air inlet 11 is also provided with an air inlet 12 at the bottom position of the inner cavity of the cabinet body 1 . The air intake fan 9 draws in the outside air through the air inlet 12, enters the air inlet duct 10, and then discharges into the cabinet 1 through the air inlet 11 on the outer wall of the air inlet duct 10, and then the hot air inside the cabinet 1 passes through the exhaust.
