The first side door 10 is fixedly connected to an air inlet box 12, and three ventilation grooves 16 are provided on the surface of the air inlet box 12. A detachable connecting baffle 161 is provided on the surface of the ventilation groove 16. The air inlet box 12 is connected to the air inlet of the two-way flow ventilation fan 6 through a first telescopic tube 14. The second side door 11 is fixedly connected to an air outlet box 15, and a ventilation hole 13 is provided on one side surface of the air outlet box 15. The air outlet box 15 is connected to the air outlet of the two-way flow ventilation fan 6 through a second telescopic tube 17.

[0024] Furthermore, the storage rack 9 has three layers of partitions 91 for placing items, and three ventilation grooves 16 correspond to the partitions 91. The partitions 91 can be used to place electronic devices such as processors. The cold air discharged from the ventilation grooves 16 cools the electronic devices. If there are partitions 91 without electronic devices placed on them, the corresponding ventilation grooves 16 can be closed by connecting baffles 161.

[0025] The first connecting tube 7 and the second connecting tube 8 both include a skin layer 23, a sound-absorbing layer 24 is arranged inside the skin layer 23, a contact layer 25 is arranged inside the sound-absorbing layer 24, and the surface of the contact layer 25 is penetrated with evenly distributed through holes 26. The sound-absorbing layer 24 is made of sound-absorbing cotton material. The first connecting tube 7 and the second connecting tube 8 are used to transmit cold air and hot air.

The three ventilation slots 16 correspond to the partition 91. The blown cold air can cool the objects on the top of the partition 91. The air outlet box 15 absorbs the hot air released by the objects, and discharges it to the two-way flow ventilation fan 6 through the second telescopic tube 17, and then discharges it to the surrounding of the first air outlet slot 3 through the second connecting pipe 8. The first connecting pipe 7 and the second connecting pipe 8 will produce sound when the air flows during operation. The sound is absorbed by the sound-absorbing layer 24 through the through hole 26, thereby reducing the noise during air circulation and reducing the noise when the chassis is working. The display panel 28 can display the internal temperature of the chassis body 1 and adjust it.
