The heat transfer plate 12 is connected to the surface of the bracket 11 close to the main plate 300, and a gap is formed between the heat transfer plate 12 and the bracket 11. As can be appreciated. The base 10 also has a supporting function.

It is understood that, in the present embodiment, the heat transfer plate 12 and the bracket 11 may be integrally formed. The heat transfer plate 12 contacts an electronic component to be cooled and receives heat generated by the electronic component, and the heat dissipation device 100 dissipates heat from the electronic component.

The heat conductive pipes 20 are substantially "U" shaped. The heat transfer pipe 20 includes a connection pipe 21, a first extension pipe 22, and a second extension pipe 23. The middle end of the heat conducting pipe 20, i.e. the connecting pipe 21, is inserted and connected to the gap between the bracket 11 and the heat transfer plate 12. The connection pipe 21 may be used to be in sufficient contact with the heat transfer plate 12 and receive heat transferred from the heat transfer plate 12. Two ends of the connecting tube 21 extend to a side away from the base 10 and away from the heat transfer plate 12, respectively, to form the first extending tube 22 and the second extending tube 23.

It is understood that the first extension pipe 22 and the second extension pipe 23 are located at both ends of the connection pipe 21, and substantially form a "U" shape with the connection pipe 21. The heat pipe 20 may be used to receive heat transferred by the heat transfer plate 12. In an embodiment, the heat pipe 20 is used to dissipate heat of the hard disk 200. It is understood that the heat conducting pipe 20 is internally provided with a heat conducting liquid which evaporates upon heat to take away the generated heat. The heat conductive pipe 20 may also transfer heat of the hard disk 200 to the first heat sink 30.

In the present embodiment, the mounting member 50 includes a holding portion 51 and a fixing portion 52. The holding portion 51 is substantially a sheet-like structure. The fixing portion 51 is sleeved on the first extension pipe 22 and the second extension pipe 23, and is disposed on the surface of the first heat sink 30 away from the base 10 to prevent the first heat sink 30 from separating from the heat pipe 20.

In the present embodiment, the fixing portion 52 is connected to the holding portion 51. Specifically, the fixing portion 52 has a substantially rectangular shape. The fixing portion 52 may be connected to both ends of the holding portion 51 for fixing the hard disk 200. Specifically, the fixing portion 52 is vertically disposed at two sides of the first heat sink 30, and one end of the fixing portion 52 is connected to the holding portion 51. In this embodiment, the mounting member 50 may be a metal plate made of metal, such as aluminum.

Specifically, the fixing portion 52 fixes an end of the hard disk 200 to the fixing portion 52 by a fixing member 522, so as to fix the hard disk 200 to the fixing portion 52. Further, the hard disks 200 are vertically installed at both sides of the heat sink 100.

In this embodiment, according to different positions of the fixing hole 521, the heat dissipation device 100 can fix hard disks with different sizes to dissipate heat of the hard disks with different sizes. In this embodiment, the heat dissipation device 100 can dissipate heat of two hard disks at the same time.
