The computer host is composed of complex electronic components, among which storage devices such as memory, hard disk, etc. are used as data storage units to store digital signals temporarily or permanently to improve the computing speed of the computer. When the storage device is in operation, heat is generated due to the relationship between the current. When the heat is too high, the operating speed of the storage device will be reduced, and in severe cases, it will even be damaged. Only a small part of the existing computer storage devices are equipped with heat dissipation devices. In these storage devices, the heat is mainly dissipated by the way that the fan rotates to form air convection to take away the heat.

Referring to FIG. 2 , it is a schematic diagram of the structure of a hard disk device provided in an embodiment of the present invention, comprising: the hard disk device 2 comprises a hard disk 21, a storage chip 22, a connector 23, and a rib 24; a plurality of the storage chips 22 are provided on the side wall of the hard disk 21 connected to the thermal paste 4, the first end of the hard disk 21 is connected to the slot 11 through the connector 23, and the adjacent second and third ends of the hard disk 21 are provided with the rib 24; wherein the edge of the rib 24 is provided with a rod groove 241 for contacting the motor device 5.

Among them, the distance between the slot 11 and the fixing rod 51 is greater than the length of the hard disk 21. The hard disk 21 and the motherboard 1 are electrically connected through the connector 23 and the slot 11, so that the connector 23 on the hard disk 21 can be smoothly inserted into the slot 11, thereby enabling the hard disk 21 and the motherboard 1 to exchange information.

It should be noted that the retaining edge 24 is a component made of elastic material, and the rod groove 241 on the retaining edge 24 is in elastic contact with the fixing rod 51.

The copper base plate 31 has a high heat dissipation efficiency and can quickly dissipate the heat from the hard disk 21 after absorbing the heat, thereby enabling the hard disk 21 to work normally.

In an optional embodiment, the heat sink 32 is made of aluminum alloy material.

It can be understood that the heat sink 32 made of aluminum alloy material is relatively light, so that the overall weight of the heat sink 3 is within the tolerance range of the hard disk 21 .

The working principle of the embodiment of the present invention is:

During installation, one side of the heat conductive paste 4 is attached to the inner side of the heat dissipation plate 3, and the other side of the heat conductive paste 4 is fixedly connected to the hard disk 21.

The edge of the retaining edge 24 of the hard disk device 2 is provided with a rod groove 241 and slides in contact with the fixed rod 51. Then the rod sleeve 52 is sleeved on the fixed rod 51 and fixed, and the motor 54 is fixedly connected to the connecting rod 53, so that the motor 54 is fixed on the main board 1, and the fan blade 55 installed on the motor 54 is directly facing the central part of the bottom plate 31, and the motor 54 is connected to the power supply. When the computer is working, the hard disk 21 records information into the storage chip 22. Under the action of the current, the temperature of the hard disk 21 rises. At this time, the motor 54 runs synchronously and rotates to drive the fan blade 55 to rotate and blow air, forming an airflow on the surface of the bottom plate 31. The airflow is divided into two directions and flows on the surface of the bottom plate 31 under the guidance of the heat sink 32 fixed on the surface of the bottom plate 31. The heat sink 32 designed as an arc surface and provided with a heat dissipation groove 321 contacts the airflow for heat exchange. The airflow continuously flows to take away the heat on the heat sink 3 and continuously blows in cold air, so that the heat sink 32 continuously dissipates heat, improves the heat dissipation efficiency, ensures the normal operation of the hard disk 21, and enables the computer to run at high speed.
