Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a hard disk cage and electronic equipment. Background Art

[0002] In electronic devices such as servers that are equipped with a large number of hard disks, fans are often used to dissipate heat from the hard disk cage. As the performance of electronic devices improves, the demand for heat dissipation also increases, and the fan speed is getting higher and higher, which leads to increased vibration / noise. Affected by the airflow generated by the high-speed fan, the performance of the hard disk at work often decreases significantly. Therefore, how to ensure good performance of the hard disk while configuring a high-speed fan has become a technical problem that needs to be solved urgently by technical personnel in this field. Summary of the invention

[0003] On the one hand, this application provides the following technical solutions:

[0004] A hard disk cage, comprising:

[0005] A box body having a first side and a second side adjacent to each other and used for accommodating a hard disk;

[0006] An air guide plate is located outside the box body and connected to the box body, and has an air guide surface facing away from the first side. The air guide plate is used to guide part or all of the airflow from the outside of the box body blowing toward the first side to the second side, so as to achieve part or all of the airflow flowing along the air guide surface and the surface of the second side.

[0007] Optionally, in the above-mentioned hard disk cage, the first side is provided with an inlet for loading the hard disk, the air guide plate is movably provided on the box body, and the air guide plate has at least a first form and a second form within the range of movement relative to the box body, when in the first form, the air guide plate blocks the inlet and the air guide surface faces away from the inlet, and when in the second form, the air guide plate is located outside directly in front of the inlet.

[0008] Optionally, in the above-mentioned hard disk cage, when the air guide plate is in the first form, a gap not blocked by the air guide plate is formed between the first edge of the air guide plate close to the second side and the edge of the inlet, and the first edge is flush with the surface of the hard disk close to the second side.

[0009] Optionally, in the above-mentioned hard disk cage, one end of the air guide plate is hinged to the box body, and the air guide plate switches between the first form and the second form by rotating relative to the box body.

[0010] Optionally, in the above hard disk cage, the box body has a third side opposite to the second side, the cross-sectional profile of the air guiding surface is arched, and the air guiding plate is used to direct the first part and the second part of the air flow to the second side and the third side respectively, so as to enable the first part of the air flow to flow along the air guiding surface and the surface of the second side, and the second part of the air flow to flow along the air guiding surface and the surface of the third side.

[0011] Optionally, in the above hard disk cage, a sound-absorbing cotton is laid on the air guiding surface.

[0012] Optionally, in the above hard disk cage, it further includes:

[0013] A heat conducting member, which is arranged on the inner surface of the box body and is used to contact the outer surface of the hard disk installed in the box body, so as to conduct the heat on the hard disk to the box body.

[0014] Optionally, in the above hard disk cage, the heat conducting member includes a heat conducting gasket and a heat conducting spring piece. The heat conducting gasket and the heat conducting spring piece are respectively located on two opposite inner surfaces of the box body, and the elastic restoring force of the heat conducting spring piece presses the hard disk against the heat conducting gasket.

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] See Figures 1 to 8, an embodiment of the present application provides a hard disk cage, including a box body 1 and a wind guiding plate 2. Among them, the box body 1 is used to accommodate the hard disk 3 and has adjacent first and second sides. That is, the box body 1, as the main body part of the hard disk cage, has an accommodation space for containing the hard disk 3. The first and second sides are two adjacent side parts of the box body 1 in space. It should be noted that the above-mentioned second side is a solid side part of the box body 1, and the above-mentioned first side can be either a solid side part of the box body 1 or a space side part of the box body 1. For example, the first and second sides are respectively shell plates that form a part of the box body 1, or the first side is the opening of the accommodation space of the box body 1, and the second side is a shell plate that forms a part of the box body 1; the wind guiding plate 2 is located outside the box body 1 and is connected to the box body 1. The wind guiding plate 2 has a wind guiding surface facing away from the first side of the box body 1. The wind guiding plate 2 is used to guide part or all of the airflow blowing towards the first side from outside the box body 1 to the second side, so as to realize part or all of the airflow flowing along the wind guiding surface and the surface of the second side. That is, at least part of the airflow blowing towards the first side flows along the wind guiding surface of the wind guiding plate 2 to the second side of the box body 1 under the action of the wind guiding plate 2. It should be noted that the airflow flowing towards the second side flowing along the surface of the second side means that the airflow flows along the inner surface and / or outer surface of the second side. That is, the airflow flowing towards the second side can finally flow only along the inner surface of the second side, or only along the outer surface of the second side, or can flow along the inner surface and outer surface of the second side in two paths.

[0031] In the case where the fan configured for the hard disk cage blows air towards the first side of the box body 1, the wind guiding plate 2 can use its wind guiding surface facing away from the first side to guide part or all of the airflow to the second side adjacent to the first side, so as to realize part or all of the above-mentioned airflow flowing along the wind guiding surface and the surface of the second side. In this way, at least part of the airflow blowing towards the first side changes direction and flows along the surface of the second side of the box body 1. Through such an airflow flow form, the disturbance of the airflow to the hard disk cage can be weakened, so that the increase of vibration / noise can be avoided as much as possible even when a high-speed fan is configured, ensuring that the working performance of the hard disk 3 is good.

[0032] In a preferred embodiment, an inlet 11 for inserting the hard disk 3 is provided on the first side. That is, the hard disk 3 is inserted into the accommodation space of the box body 1 through the inlet 11. The air guide plate 2 is movably arranged on the box body 1. The air guide plate 2 has at least a first form and a second form within the range of relative movement with respect to the box body 1. When in the first form, the air guide plate 2 blocks the inlet 11 and the air guide surface faces away from the inlet 11. When in the second form, the air guide plate 2 is located outside the front of the inlet 11. That is, the air guide plate 2 avoids the space required in front of the inlet 11 when inserting the hard disk 3. That is to say, when the air guide plate 2 is in the second form, it will not interfere with the hard disk 3 entering and exiting the box body 1. In the above structure, when the air guide plate 2 is in the first form, it can direct part or all of the air flow blowing from outside the box body 1 towards the inlet 11 to the side of the box body 1 adjacent to the inlet 11. In this way, while acting as a cover plate for the inlet 11, the air guide plate 2 plays a role in directing at least part of the air flow to the second side of the box body 1.

[0033] In order to movably arrange the air guide plate 2 on the box body 1, there are various connection forms between the air guide plate 2 and the box body 1. For example, the air guide plate 2 can be hinged to the box body 1, so as to realize that the air guide plate 2 can rotate relative to the box body 1, as Figure 1 , Figure 2 , Figure 5 and Figure 6 shown. One end of the air guide plate 2 is hinged to the box body 1. The air guide plate 2 realizes the switching between the first form and the second form by rotating relative to the box body 1. That is, after the air guide plate 2 is lifted outwards from the inlet 11, it is in the aforementioned second form. Rotating the air guide plate 2 to buckle towards the inlet 11 can switch from the second form to the aforementioned first form. For another example, the air guide plate 2 can be slidably connected to the box body 1, so as to realize that the air guide plate 2 can slide relative to the box body 1. By sliding the air guide plate 2, its relative position with respect to the box body 1 is changed, so that it can be switched between the aforementioned first form and the second form.

[0034] In addition, in other embodiments, the first side of the box body 1 may also be the side that does not have the inlet 11 provided, but also needs to avoid the direct blowing of the air flow. At this time, the air guide plate 2 can be arranged to be movably connected or fixedly connected to the box body 1 according to needs.

[0035] As Figure 1 and Figure 2 shown, in this embodiment, a plurality of inlets 11 are arranged side by side on the first side of the box body 1, and the air guide plate 2 is arranged corresponding to each inlet 11 one by one. It is easy to understand that the air guide plate 2 and the inlet 11 can also be arranged in a one-to-many form, that is, one air guide plate 2 can block at least two inlets 11 at the same time.

[0036] ​In a preferred embodiment, when the air guide plate 2 is in the first state, a gap not blocked by the air guide plate 2 is formed between the first edge of the air guide plate 2 near the second side and the edge of the inlet 11, and the first edge is flush with the surface of the hard disk 3 near the second side. Figure 7 and Figure 8 As shown, the right side of the box body 1 in the figure is the aforementioned first side, the lower side of the box body 1 is the aforementioned second side, the first edge is the lower edge of the air guide plate 2 (including the plate body 21 and the sound-absorbing cotton 22) in the figure, and the first edge is flush with the lower surface of the hard disk 3 in the figure. Since there is a gap between the lower surface of the hard disk 3 and the inner surface of the box body 1, a gap is formed between the first edge and the edge of the corresponding second side of the inlet 11. The air outlet of the fan faces the first side of the box body 1, which can cool the hard disk cage. The airflow from the fan blowing toward the first side of the box body 1 flows to the second side of the box body 1, that is, the lower part of the box body 1 in the figure, under the action of the air guide plate 2. Since a gap is formed between the lower edge of the air guide plate 2 and the edge of the inlet 11, the airflow passes through the gap into the gap between the lower surface of the hard disk 3 and the inner surface of the box body 1, and flows along the lower surface of the hard disk 3 and the inner surface of the second side of the box body 1. In this way, the airflow can more efficiently take away the heat generated by the hard disk 3. Figure 7 and Figure 8 It can be seen that the air guide surface of the air guide plate 2 can be paved with sound-absorbing cotton 22, which can further reduce the noise generated when the airflow blows onto the hard disk cage.

[0037] In addition, in other embodiments, the first edge of the air guide plate 2 can also be set to be flush with the outer surface of the second side of the box body 1 when the air guide plate 2 is in the first form, that is, the air guide plate 2 completely blocks the inlet 11. At this time, the airflow flowing to the second side under the action of the air guide plate 2 will flow along the outer surface of the second side and take away the heat on the box body 1.

[0038] In order to improve the heat dissipation effect, in a preferred embodiment, the hard disk cage may further include a heat conductive member, which is arranged on the inner surface of the box body 1 and is used to contact the outer surface of the hard disk 3 installed in the box body 1 to conduct the heat on the hard disk 3 to the box body 1. Specifically, the heat conductive member may include a heat conductive pad 4 and / or a heat conductive spring 6, for example, Figure 7 In the exemplary structure shown, the heat conducting member is a thermally conductive gasket 4 arranged on the upper and lower inner surfaces of the box body 1. After the hard disk 3 is installed in the box body 1, it contacts the thermally conductive gasket 4. The thermally conductive gasket 4 located at the bottom in the figure conducts the heat from the hard disk 3 to the second side of the box body 1, and the thermally conductive gasket 4 located at the top conducts the heat from the hard disk 3 to the third side of the box body 1 opposite to the second side. Figure 8 The exemplary structure shown is Figure 7The difference lies in that the heat-conducting gasket 4 located at the lower part in the figure is replaced with a heat-conducting elastic piece 6. The elastic restoring force of the heat-conducting elastic piece 6 squeezes the hard disk 3 towards the heat-conducting gasket 4. That is to say, while the heat-conducting elastic piece 6 conducts the heat on the hard disk 3 to the second side of the box body 1, it also enhances the contact force between the hard disk 3 and the heat-conducting component, thereby improving the stability of the hard disk 3 in the box body 1 and ensuring reliable contact between the hard disk 3 and the heat-conducting component. In addition, in other embodiments, the Figure 7 in the heat-conducting gasket 4 can be entirely replaced with Figure 8 the heat-conducting elastic piece 6 in

[0039] Refer to Figure 7 and Figure 8 , the heat on the hard disk 3 is conducted to the second side and the third side of the box body 1 through the heat-conducting component, that is, the lower side part and the upper side part of the box body 1 in the figure. The air-guiding surface of the air-guiding plate 2 is set to an arc shape, and all the airflows blown from the fan 5 towards the first side of the box body 1 are guided to the second side. In order to improve the air-cooling efficiency, in a preferred embodiment, the cross-sectional profile of the air-guiding surface can be set to an arch shape. The air-guiding plate 2 is used to guide the first part and the second part of the airflows to the second side and the third side respectively, so as to enable the first part of the airflows to flow along the air-guiding surface and the surface of the second side, and the second part of the airflows to flow along the air-guiding surface and the surface of the third side. That is, after the airflows from the blower are blown onto the hard disk cage, they are guided by the air-guiding plate 2 and flow along the two opposite side parts of the box body 1 in two paths, while taking away the heat of these two side parts. Specifically, the arch-shaped air-guiding surface can be set to a semi-circular shape or a semi-elliptical shape.

The fan 5 is located outside the box body 1, and the air outlet of the fan 5 is arranged towards the first side of the box body 1.
