A structure of dissipating heat and shielding EMI of hard disk for internet refrigerator}

The present invention relates to an internet refrigerator, and more particularly, to a heat dissipation and electromagnetic shielding structure of a hard disk for an internet refrigerator capable of shielding electromagnetic waves while effectively dissipating heat generated from a hard disk, and protecting a hard disk substrate. .

Recently, Internet refrigerators have been provided that add a computer function to the general functions of refrigerators for storing food. The internet refrigerator performs various functions such as performing internet communication while performing a function of a general refrigerator.

1 shows an internet refrigerator, FIG. 2 shows a configuration of a base according to the prior art, and FIG. 3 shows a heat radiation and electromagnetic shielding structure of a hard disk for an internet refrigerator according to the prior art.

As shown in the figure, a storage compartment is formed inside the main body 10 of the refrigerator, and doors 12a and 12b for opening and closing the storage compartment are provided at both sides of the main body 10. The display unit 14 is installed on the front surface of the door 12b on one side of the doors 12a and 12b. The display unit 14 displays various information related to the operation of the refrigerator and the Internet to the outside, and is connected to the control device 16 installed on the upper portion of the main body 10 through a cable.

As shown in FIG. 2, the control device 16 includes a base 20 on which a plurality of printed circuit boards on which various electrical elements are installed for electrical control of a refrigerator and control of the Internet. Is provided, the hard disk 22 is installed on one side of the base 20.

The hard disk 22 stores various kinds of information for controlling the Internet refrigerator. In addition, a hard disk substrate 24 controlling the hard disk 22 is mounted on one side of the hard disk 22.

Electrically connected.

Meanwhile, the hard disk 22 generates a certain heat while operating. Therefore, if the heat generated in the hard disk 22 does not dissipate to the outside, the internal temperature of the hard disk case 26 continues to rise, causing malfunction of the hard disk 22, or further, the hard disk 22 It can also shorten the life.

Therefore, in order to dissipate heat generated in the hard disk 22 to the outside, as shown in FIG. 3, the upper surface 26a of the hard disk case 26 is the hard disk 22 and the hard disk substrate. An opening portion 26c is formed at the center to shield a portion of the upper surface of the 24, and both side surfaces 26b of the hard disk case 26 are part of both side surfaces of the hard disk 22 and the hard disk substrate 24. It is formed to shield.

Therefore, the hard disk 22 is exposed to the outside, except for a part of the upper surface and both sides of the shielded by the hard disk case 26. Therefore, the hard disk 22 can dissipate heat generated in the hard disk 22 to the outside through the exposed portion. The hard disk 22 and the hard disk case 26 have bolts B1 fastened to a plurality of fastening holes formed at both side surfaces of the hard disk 22 and both side surfaces 26b of the hard disk case 26. By being combined.

However, the heat dissipation structure of the hard disk for the Internet refrigerator according to the prior art having such a configuration has the following problems.

The hard disk 22 generates not only heat but also electromagnetic waves during operation. Therefore, when the hard disk case 26 is formed as described above, heat generated in the hard disk 22 can be sufficiently dissipated, but electromagnetic waves generated in the hard disk 22 are also hard disk case 26. Electromagnetic interference (EMI) may be emitted from the top, both sides, and the front and the rear of the hard disk 22 other than the portion shielded by the top surface 26a and the both sides 26b of .

In addition, since the hard disk substrate 24 provided on one side of the hard disk 22 is exposed to the outside through the opening 26c or the like, portions other than the portion shielded by the hard disk case 26 are exposed to the outside. The hard disk substrate 24 may be damaged by an external impact or the like.

The present invention is to solve such a conventional problem, an object of the present invention, while dissipating heat generated in the hard disk to the outside effectively, the Internet refrigerator hard disk that can shield the electromagnetic waves generated from the hard disk To provide a heat dissipation and electromagnetic shielding structure.

Another object of the present invention is to provide a heat dissipation and electromagnetic shielding structure of a hard disk for an internet refrigerator capable of protecting a hard disk substrate.
