[0002] Network Attached Storage (NAS) is a storage system connected to the network, which allows many users and applications to access, store and share data through the network. NAS generally has its own IP address, which enables it to be accessed through a local area network (LAN) or a wide area network (WAN). Whether in an enterprise environment or a personal home environment, NAS is often used to complete tasks such as file sharing, data backup and recovery.

[0003] The hard disk, circuit board and other components in the NAS generate a lot of heat during operation. At present, fans are generally installed inside the NAS to dissipate heat. Dissipation heat means that the fan is installed near the air outlet and blows air toward the air outlet.

[0031] The hard disk insertion space 21 is connected to the fan 5 to form a main air duct 6; the main control circuit board 4 is installed below the installation frame 2 and is spaced apart from the installation frame 2 to form a main control circuit board air duct 7; the main control circuit board air duct 7 is connected to the main air duct 6; the fan 5 drives the outside air to enter the main air duct 6 and the main control circuit board air duct 7 from the air inlet 111.

[0032] The utility model provides a network attached storage device with a mounting frame 2 to form a main air duct 6, a first hard disk 3 is inserted into the hard disk insertion space 21 of the mounting frame 2, the main air duct 6 is connected with the main control circuit board air duct 7, and a fan 5 is installed between the rear end of the mounting frame 2 and the rear cover 11, and is arranged corresponding to the air inlet 111 of the rear cover 11. In this way, the outside air is only drawn into the inside of the network attached storage device from the air inlet 111, and the fan 5 blows the air mainly to the main air duct 6 and the main control circuit board air duct 7, and finally, the air can be blown out from the gaps around the network attached storage device to achieve heat dissipation. In this heat dissipation method, the outside air is only drawn into the inside of the network attached storage device from the air inlet 111, and less dust enters. Moreover, since the fan 5 is always blowing out to dissipate heat, the dust inside is also easily blown to the outside, and dust is not easy to accumulate in the gaps around or inside the network attached storage device.

[0033] It is also important that the fan 5 of the utility model is directly connected to the main air duct 6 formed by the hard disk insertion space 21, and is connected to the main control circuit board air duct 7, which can directly and effectively dissipate the heat of the components with the largest heat generation in the network attached storage, namely the first hard disk 3 and the main control circuit board 4, and the heat dissipation effect is better.
