[0002] Existing data storage devices dissipate heat by means of a single fan sucking air under negative pressure. However, when dissipating heat with a single fan, there are heat dissipation dead corners where air cannot reach, which easily causes the chips in the heat dissipation dead corner area to crash. Moreover, the heat dissipation efficiency of a single fan is relatively low and cannot fully meet the heat dissipation requirements of the data storage device. Summary of the Utility Model

[0003] The utility model provides a heat dissipation structure for a data storage device to overcome the technical problems of heat dissipation dead corners where air cannot reach and low heat dissipation efficiency when dissipating heat with a single fan.

[0004] To achieve the above object, the technical solution of the utility model is as follows:

[0005] A heat dissipation structure for a data storage device includes: a main housing, a first heat dissipation fan, and a second heat dissipation fan; the main housing is provided with a receiving cavity for accommodating the data storage device, and the data storage device is arranged in the receiving cavity; the first heat dissipation fan and the second heat dissipation fan are misaligned and installed on opposite side walls of the main housing, and the first heat dissipation fan and the second heat dissipation fan are respectively opposite to a first air duct opening and a second air duct opening provided on the side wall of the data storage device.

[0006] Further, the main housing includes a mounting frame, mounting plates respectively provided on adjacent two sides of the mounting frame, and a mounting frame; the mounting frame, the mounting plates, and the mounting frame form a receiving cavity for accommodating the data storage device.

[0007] Further, the data storage device includes a front cover, a hard disk box, and a hard disk. The hard disk box is arranged in the receiving cavity and is connected to the front cover at one end. The hard disk is arranged in the hard disk box in a suspended manner, and the first air duct opening and the second air duct opening are respectively provided on both side walls of the hard disk box.

[0008] Further, the first heat dissipation fan is arranged at one end of the side wall of the main housing close to the front cover, and the first heat dissipation fan is a blowing fan; the second heat dissipation fan is arranged at one end of the side wall of the main housing far from the front cover, and the second heat dissipation fan is a suction fan.

[0009] Further, both the first air duct opening and the second air duct opening are annular air duct openings composed of a plurality of through holes.

[0010] Further, each of the through holes is in an elliptical shape.

[0011] Further, on one side of the front cover close to the hard disk box, a first positioning pin column and a second through hole are oppositely provided. On one side of the mounting bracket close to the front cover, a first positioning pin column mounting hole and a second threaded hole are oppositely provided. After the mounting bracket and the front cover are connected in a matching manner through the first positioning pin column and the first positioning pin column mounting hole, they are fixed with screws.

[0012] Further, both the first cooling fan and the second cooling fan are axial fans.

[0013] Beneficial effects: In the utility model, the double fans composed of the first cooling fan and the second cooling fan work together. The first cooling fan blows air inward at one end of the data storage device, and the second cooling fan sucks air outward at the other end of the data storage device, so that air rapidly flows inside the data storage device through the first air duct opening and the second air duct opening, thereby quickly taking away the heat generated by the data storage device, without heat dissipation dead angles, and ensuring the stable operation of the data storage device.

Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] This embodiment provides a heat dissipation structure for a data memory, as Figure 1 shown, a main housing 1, a first cooling fan 2 and a second cooling fan 3; the main housing 1 is provided with a receiving cavity for receiving the data memory 4, and the data memory 4 is disposed in the receiving cavity; the first cooling fan 2 and the second cooling fan 3 are staggeredly installed on opposite side walls of the main housing 1, and the first cooling fan 2 and the second cooling fan 3 are respectively opposite to a first air duct opening 21 and a second air duct opening 31 provided on the side wall of the data memory 4.

[0022] Specifically, in this embodiment, by providing the first cooling fan 2 and the second cooling fan 3, a dual-fan is formed to work cooperatively. Among them, the first cooling fan blows air inward at one end of the data memory 4, and the second cooling fan sucks air outward at the other end of the data memory 4, so that air enters the interior of the data memory through the first air duct opening and flows out through the second air duct opening, thereby enabling the air to fully flow inside the data memory to take away the heat generated by the data memory and ensuring the stable operation of the data memory.

[0023] In a specific embodiment, as Figure 2 shown, the main housing 1 includes a mounting frame 11, mounting plates 12 and a mounting frame 13 respectively provided on adjacent sides of the mounting frame; the mounting frame 11, the mounting plates 12 and the mounting frame 13 form a receiving cavity for receiving the data memory; as Figure 2 shown, the mounting frame 11 includes two side walls and a cross beam, the two side walls are connected by the cross beam in the middle, and the two side walls are respectively located at both ends of the mounting plate 12, the mounting frame 13 is opposite to the cross beam and is respectively connected to the two side walls and the mounting plate 12.

[0024] Specifically, the two side walls of the mounting frame 11 are respectively provided with mounting grooves for mounting the cooling fans, and the two cooling fans are respectively disposed in the mounting grooves and fixed by screws.

[0025] In a specific embodiment, the first cooling fan 2 is disposed at one end of the side wall of the main housing close to the front cover 41, and the first cooling fan is a blowing fan; the second cooling fan 3 is disposed at one end of the side wall of the main housing away from the front cover 41, and the second cooling fan is a suction fan. Specifically, a dual-fan solution of blowing on one side and sucking on the other side is adopted to meet the requirement of sufficiently cooling the data memory and avoid the existence of heat dissipation dead angles.

[0026] In a specific embodiment, the data memory 4 includes a front cover 41, a hard disk box 42, and a hard disk 43. The hard disk box 42 is disposed in the accommodation cavity and one end thereof is connected to the front cover 41. The hard disk 43 is disposed in the hard disk box 42 in a suspended manner, and the first air duct opening 21 and the second air duct opening 31 are respectively provided on both side walls of the hard disk box 42.

[0027] In this embodiment, as Figure 3 and Figure 4 shown, the hard disk box 42 is an integral structure, including a bottom plate, side plates provided on both sides of the bottom plate, and upper side plates respectively connected to the side plates at an angle. A plurality of threaded posts are respectively provided on both side walls of the hard disk 43, and screw holes are respectively provided on both side plates of the hard disk box 42. The hard disk 43 and the hard disk box 42 are connected by screws; the size of the hard disk box is larger than that of the hard disk, and the hard disk is disposed in the hard disk box in a suspended state, so that there is a gap between the bottom plate of the hard disk box 42 and the bottom plate of the hard disk 43, a gap between the side plates of the hard disk box 42 and the side plates of the hard disk 43, and a gap between the upper side plate of the hard disk box 42 and the upper cover of the hard disk 43. And when the data memory 4 is installed in the accommodation cavity, a gap for ensuring air circulation is also formed between the upper cover of the hard disk 43 and the mounting plate 12. During heat dissipation, air enters from the first air duct opening 21, then circulates through a plurality of gaps, thereby taking away the heat generated by the hard disk and flowing out from the second air duct opening to achieve the heat dissipation function.

[0028] Specifically, in this embodiment, the material of the hard disk box is selected as a galvanized steel plate with a thermal conductivity of 60 W / (m·K). The galvanized steel plate has the characteristics of high strength, high heat dissipation performance, and corrosion resistance.

On the side of the mounting bracket 11 close to the front cover 41, a positioning pin post mounting hole 111 and a threaded hole are oppositely provided. The mounting bracket 11 and the front cover 41 are connected by matching the positioning pin post and the positioning pin post mounting hole 111 and then fixed by screws.

[0030] In a specific embodiment, both the first air duct opening 21 and the second air duct opening 31 are annular air duct openings composed of a plurality of through holes. Specifically, in this embodiment, preferably, each air duct opening is provided with eight through holes, and each of the through holes is elliptical in shape with a size of 8x4 mm, so that air can fully enter the data memory through the air duct opening, ensuring the maximum ventilation effect under the condition of stable air pressure.

[0031] Specifically, according to the designed air duct, both the first cooling fan 2 and the second cooling fan 3 are selected as axial fans. According to the installation space of the cooling fans, the sizes of both the first cooling fan 2 and the second cooling fan 3 are 50*50*10 mm, and the calculation of the required air volume is as follows:

[0032] According to the empirical formula: Q = 1.76*W / △T

[0033] Wherein, Q is the air volume; W is the total power, and W = 35 w; △T is the allowable temperature rise, and △T = 10°C.

[0034] In this embodiment, according to the air volume requirement, the operating points of the first cooling fan 2 and the second cooling fan 3 are designed at 1 / 2 - 2 / 3 of the air volume.

[0035] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
