[0028] Embodiment 1:

[0029] Please refer to Figures 1-5 The above technical solutions are described in detail by the following embodiments.

[0030] A cabinet type network server comprises:

[0031] The cabinet 1 comprises a plurality of stands 11, the top of the stand 11 is provided with a top plate 15, the top plate 15 is provided with a fan 16 above, a plurality of servers 4 are stacked and installed between the stands 11 through crossbars 12, the servers 4 are provided with auxiliary air ducts 3 on the left and right sides, the auxiliary air ducts 3 are provided with main air ducts 2 on the front and back sides, the main air ducts 2 transmit the negative pressure generated by the fan 16 to the servers 4, and the auxiliary air ducts 3 are used for conveying hot air between the servers 4 to the fan 16.

[0032] The fan cover 17 is fixedly installed above the top plate 15 through screws, the fan cover 17 wraps the fan 16, and the fan cover 17 is a perforated metal plate.

[0033] The stand 11 is used for supporting the main body, the bottom of the stand 11 is fixedly installed with a bottom plate 13 through screws, and the edge of the bottom plate 13 and the outer side of the top plate 15 are fixedly installed with side plates 14 through screws.

[0034] The cabinet door 18 is rotatably installed on the front and back sides of the stand 11 through hinges and other rotating elements. The cabinet door 18 is a perforated metal plate and a square steel pipe welded together.

[0035] The main air duct 2 comprises a main air pipe 21 fixedly installed outside the cross bar 12, and a first air outlet 22 is arranged at the top of the main air pipe 21 and located below the fan 16.

[0036] When the fan 16 works, air can be discharged to the outside, and negative pressure is generated below. The first air outlet 22 is half the size of the fan 16, and can transmit part of the negative pressure of the fan 16 to the inside of the main air pipe 21. The remaining part of the fan 16 is blocked, and negative pressure can still be generated in the cabinet 1 to discharge hot air on both sides of the server 4.

[0037] A first air inlet pipe 23 is horizontally arranged outside the middle of the main air pipe 21 and located between two adjacent servers 4.

[0038] The negative pressure in the main air pipe 21 can be transmitted to the first air inlet pipe 23, and the hot air between the servers 4 can enter the main air pipe 21 from the first air inlet pipe 23 and then be discharged from the fan 16.

[0039] A guide plate 24 is rotatably installed inside the head of the first air inlet pipe 23, and a power source 25 is connected to the guide plate 24. When the power source 25 works, it can drive the guide plate 24 to rotate.

[0040] The power source 25 can be a rudder, which is fixedly installed outside the first air inlet pipe 23 by screws, and the output shaft of the power source 25 is connected to the guide plate 24. When the power source 25 works, it can drive the guide plate 24 to rotate, thereby changing the ventilation area of the first air inlet pipe 23 and the amount of air entering the first air inlet pipe 23, so as to control the cooling effect of the servers 4 at different heights.

[0041] The auxiliary air duct 3 comprises an auxiliary air outlet pipe 31 fixedly installed outside the cross bar 12 and located between the main air pipes 21, and the top opening of the auxiliary air outlet pipe 31 is higher than the topmost server 4.

[0042] When the fan 16 works, negative pressure can be generated above the topmost server 4, thereby generating negative pressure at the top opening of the auxiliary air outlet pipe 31.

[0043] An auxiliary air outlet pipe 31 is connected to a second air inlet pipe 32 outside the middle of the auxiliary air outlet pipe 31, and a second fan 33 is arranged between two adjacent servers 4 below the second air inlet pipe 32. The second fan 33 is used to inject air into the second air inlet pipe 32.

[0044] The second fan 33 is a centrifugal fan, which can send the hot air between two adjacent servers 4 into the auxiliary air outlet pipe 31 through the second air inlet pipe 32, and then discharge the hot air from the top of the auxiliary air outlet pipe 31, and finally discharge the hot air outside the cabinet 1 by the fan 16.

[0045] A temperature detection component 34 is provided on the outside of the second air inlet duct 32. The temperature detection component 34 is used to detect the ambient temperature.

[0046] When the temperature detection component 34 detects that the ambient temperature is high, it controls the corresponding power source 25 to work, driving the guide plate 24 to rotate to a horizontal state, so as to maximize the ventilation volume.

[0047] If the temperature still does not drop effectively, control the second fan 33 to operate, actively draw in hot air and discharge it from the auxiliary exhaust pipe 31.

[0048] In this embodiment, when the operator uses this device, the temperature detection component 34 is used to detect the temperature between two adjacent servers 4.

[0049] When the temperature detection component 34 detects that the ambient temperature is high, it controls the corresponding power source 25 to work, driving the guide plate 24 to rotate to a horizontal state, so as to maximize the ventilation volume.

[0050] At this time, the fan 16 is working and can exhaust air to the outside, creating negative pressure below. The first exhaust port 22 can transfer a portion of the negative pressure from the fan 16 to the inside of the main air duct 21.

[0051] The negative pressure inside the main air duct 21 can draw in hot air from the first air inlet duct 23 and then discharge it from the first exhaust port 22 at the top of the main air duct 21.

[0052] If the temperature still does not drop effectively, control the second fan 33 to operate, actively draw in hot air and discharge it from the auxiliary exhaust pipe 31.

[0053] Cold air from outside can enter through cabinet door 18, effectively cooling server 4.
