Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and particularly relates to a box body structure and an electrical equipment. Background Art

[0002] When the dense hard disks inside an electrical equipment such as a JBOD system are working, a large amount of heat will be generated. If the heat is not dissipated in time, the temperature of the JBOD will rise, affecting the performance and service life of the hard disks. Generally, the heat dissipation solution for the JBOD is to blow the hot air out of the JBOD through a fan, and the fan is installed at the rear of the JBOD. If the air duct design is unreasonable, it will cause the temperature at the front of the JBOD to be low and the temperature at the rear to be high, increasing the probability of failures.

[0003] In the related art, referring to the attached Figure 1 , in a traditional JBOD storage server device, the hard disks 2' are mainly cooled by the cooling fans built in its chassis 1'. However, there is also a centralized cooling by a shared type fan wall 3' arranged on the rear wall or the front wall of the cabinet. The cooling air flow is to cross the entire device from one end to the other end for cooling. However, in this way, the temperature of the air flow will gradually increase during the flowing process, and the cooling effect on the hard disks 2' near the air inlet is better, while the cooling effect on the hard disks 2' far from the air inlet is worse, and the overall structure has uneven heat dissipation.

The installation area includes a plurality of installation sub-areas distributed along the first direction. The plurality of installation sub-areas are used for installing a plurality of heat-generating elements. The installation area communicates with the air inlet channel and the air outlet channel at positions corresponding to the plurality of installation sub-areas.

[0011] In one embodiment, the air outlet is disposed on a side of the box body opposite to the air inlet channel.

[0012] In one embodiment, the first direction is the horizontal direction, and the second direction is the up-down direction;

[0013] The air outlet channel is located above the installation area, and the air inlet channel is located below the installation area.

[0014] The present utility model further provides an electrical device, which includes a box body structure. The box body structure includes a box body, an air inlet and an air outlet are provided on the box body. An air inlet channel and an air outlet channel extending in the first direction are defined inside the box body. The air inlet channel and the air outlet channel are spaced apart in the second direction to define an installation area therebetween. The installation area includes a plurality of installation sub-areas distributed in the first direction, and the plurality of installation sub-areas are used for installing a plurality of heating elements. The installation area communicates with the air inlet channel and the air outlet channel at positions corresponding to the plurality of installation sub-areas. Wherein, the first direction and the second direction intersect;

[0015] The electrical device further includes a plurality of heating elements and a driving structure. The plurality of heating elements are correspondingly disposed in the plurality of installation sub-areas; the driving structure is used to drive the air flowing into the box body from the air inlet to flow through the air inlet channel, the installation area, and the air outlet channel and then be discharged from the air outlet.

[0016] In one embodiment, the electrical device includes a server, and the plurality of heating elements include a backplane and a plurality of hard disks.

[0017] In one embodiment, the electrical device further includes a power supply and / or an expansion board, and the power supply and / or the expansion board are located on one side of the plurality of hard disks in the first direction.

Since the air inlet passage extends along the first direction, when the cold air enters the installation area, it can enter each of the installation sub-areas through the positions of the installation area corresponding to the plurality of installation sub-areas, so as to dissipate heat from the heating elements installed in each of the installation sub-areas. After taking away the heat, the hot air is discharged from the air outlet through the air outlet passage.

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

[0028] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution where A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0030] When electrical equipment such as a JBOD system has densely packed hard disks working, a large amount of heat will be generated. If the heat is not dissipated in time, it will cause the temperature of the JBOD to rise, affecting the performance and lifespan of the hard disks. Generally, the heat dissipation solution for the JBOD is to blow the hot air out of the JBOD through a fan, and the fan is installed at the rear of the JBOD. If the air duct design is unreasonable, it will cause the temperature at the front of the JBOD to be low and the temperature at the rear to be high, increasing the probability of failures.

[0031] In the related art, referring to the attached Figure 1, in a traditional JBOD storage server device, the hard disks 2' are mainly cooled by the cooling fans built in its chassis 1'. However, there is also a centralized cooling method using a shared fan wall 3' installed on the rear wall or front wall of the cabinet. The cooling air flow dissipates heat by crossing the entire device from one end to the other. However, this method causes the temperature of the air flow to gradually increase during the flow process, resulting in a better cooling effect on the hard disks 2' near the air inlet and a worse cooling effect on the hard disks 2' far from the air inlet, and the overall structure has uneven heat dissipation.

[0032] The present utility model proposes a box structure and an electrical device, aiming to at least solve the technical problem of uneven heat dissipation when multiple heat-generating components are concentrated.

[0033] Please refer to Figures 2 to 4 , in an embodiment of the present utility model, a box structure 100 includes a box body 1. An air inlet 11 and an air outlet 12 are provided on the box body 1. An air inlet channel 13 and an air outlet channel 14 extending along a first direction are defined inside the box body 1. The air inlet channel 13 and the air outlet channel 14 are spaced apart in a second direction to define an installation area 15 therebetween. The installation area 15 includes a plurality of installation sub-areas distributed along the first direction, and the plurality of installation sub-areas are used for installing a plurality of heat-generating elements 4. The installation area 15 communicates with the air inlet channel 13 and the air outlet channel 14 at positions corresponding to the plurality of installation sub-areas, wherein the first direction and the second direction intersect.

[0034] In the technical solution of the present utility model, an air inlet channel 13 and an air outlet channel 14 extending along a first direction are defined inside the box body 1. The air inlet channel 13 and the air outlet channel 14 are spaced apart in a second direction to define an installation area 15 therebetween. The installation area 15 includes a plurality of installation sub-areas distributed along the first direction, and the plurality of installation sub-areas are used for installing a plurality of heat-generating elements 4. The installation area 15 communicates with the air inlet channel 13 and the air outlet channel 14 at positions corresponding to the plurality of installation sub-areas, and the first direction and the second direction intersect; thus, after the cold air enters the air inlet channel 13 inside the box body 1 through the air inlet 11, it flows to the installation area 15. Since the air inlet channel 13 extends along the first direction, when the cold air enters the installation area 15, it can enter each of the installation sub-areas through the positions of the installation area 15 corresponding to the plurality of installation sub-areas, so as to be able to dissipate heat from the heat-generating elements 4 installed in each of the installation sub-areas. After taking away the heat, the hot air is discharged from the air outlet 12 through the air outlet channel 14; with such a setting, the overall structure enables the cold air to flow through each heat-generating element 4 for heat dissipation, and the heat dissipation is more uniform.

[0035] In order to enable the cold air in the air inlet channel 13 to flow faster towards the installation area 15 without accumulating in the air inlet channel 13, so as to dissipate heat from the heating elements 4 in each installation sub-area, in an embodiment of the present invention, please refer to Figure 2 and Figure 4 , the air inlet 11 is arranged on one side of the box body 1 in the first direction; the side wall of the air inlet channel 13 opposite to the installation area 15 is inclined towards the air inlet 11 in a direction away from the installation area 15. With such a setting, after the cold air enters the air inlet channel 13 from the air inlet 11, under the action of an inclined side wall of the air inlet channel 13, the cold air flowing along the first direction is guided to flow along the second direction, so that it can flow towards the installation area 15 more quickly, and the heat dissipation effect is better. In another embodiment of the present invention, multiple pipes can be arranged to face each installation sub-area, but compared with the method of guiding the wind direction through an inclined surface, the structure is relatively complex. It can be understood that enabling the cold air in the air inlet channel 13 to flow faster towards the installation area 15 is not limited to this. The air inlet 11 can be set to directly face the installation area 15. In this way, by using the direct blowing method, after the cold air enters from the air inlet 11, it can also quickly reach the installation area 15. However, since the multiple heating elements 4 in the installation area 15 are distributed along the first direction, in order to ensure the uniformity of heat dissipation of each heating element 4, the air inlet 11 needs to be set very large. Under the action of the same wind force, it is difficult to ensure that the cold air will enter evenly from the air inlet 11, and when multiple box body structures 100 are stacked, it will affect the flow of air in another box body structure 100.

[0036] There are various ways to make the side wall of the air inlet channel 13 opposite to the installation area 15 inclined. In an embodiment of the present invention, please refer to Figure 2 , at least a part of a side wall of the box body 1 in the second direction is inclined to form the side wall of the air inlet channel 13 opposite to the installation area 15. In another embodiment, an inclined diversion plate can be arranged in the air inlet channel 13 to guide the wind direction to change from the first direction to the second direction; in comparison, directly setting a side wall of the box body 1 to be inclined to form the inclined side wall of the air inlet channel 13 can save materials and the production is simpler, and the external dimension of the box body 1 will be smaller.

[0037] It can be understood that if the heating element 4 is directly installed on a side wall of the box body 1, to a certain extent, it will hinder the diffusion of cold air and lead to a poor heat dissipation effect. Therefore, in an embodiment of the present invention, please refer to Figure 2 and Figure 3, the cabinet structure 100 further includes a support member 2 disposed in the cabinet 1, and the support member 2 is used to suspend the plurality of heating elements 4 in the installation area 15. With this arrangement, the heating elements 4 can be supported by the support member 2, so that there is a certain gap between the heating elements 4 and the air inlet passage 13, which is beneficial to the diffusion of the cold air entering the cabinet 1; at the same time, when one side wall of the cabinet 1 is inclined, it is not convenient to directly install the heating elements 4, and the arrangement of the support member 2 can make the installation of the heating elements 4 more convenient.

[0038] There are various specific forms of the support member 2. For example, a directly fixed bracket can be used to lift the heating element 4. However, for some heating elements 4, please refer to Figure 3 , for example, the backplane 42 and the hard disk 41 need to be installed horizontally. As a circuit board, many electronic components on the surface of the backplane 42 make it not flat itself. When using a fixed bracket to support the backplane 42, it can usually only adapt to a single model of the backplane 42, and the versatility is low; therefore, in the embodiments of the present invention, please refer to Figure 2 and Figure 3 , the support member 2 includes a plurality of support portions 21 extending in the second direction, and one end of the support portion 21 is threadedly connected to the opposite side wall of the air inlet passage 13 and the installation area 15; thus, the plurality of support portions 21 threadedly connected to one side wall of the air inlet passage 13 can adjust their own heights, and can also adjust the height of one or more of the support portions 21 in response to the heating element 4 with a complex shape, so as to be able to adapt to different shapes of the heating elements 4, and the application range is wide.

[0039] The air outlet 12 can be arranged at any position of the cabinet 1. However, when the air outlet 12 is arranged on one side wall of the cabinet 1 in the first direction, the cold air in the air inlet passage 13 may not flow through the entire installation area 15 and directly discharge from the air outlet 12, resulting in poor heat dissipation effect. Therefore, in the embodiments of the present invention, please refer to Figure 2 and Figure 4 , the air outlet 12 is arranged on the side of the cabinet 1 opposite to the air inlet passage 13. With this arrangement, the air flow path in the cabinet 1 is optimized, so that the cold air can flow through the entire installation area 15 as much as possible, improving the heat dissipation effect.

[0040] In order to improve the efficiency of hot air exhausting from the interior of the box body 1, in an embodiment of the present utility model, a side wall of the box body 1 opposite to the air inlet channel 13 is missing to form an opening, and the opening constitutes the air outlet 12. In this way, the air outlet 12 for the hot air to flow out of the box body 1 is relatively large, and when installing or removing the heating element 4, the air outlet 12 can be used as an opening for user operation, which is convenient to use.

[0041] The first direction can be a horizontal direction or a vertical direction, and the same applies to the second direction. It can be understood that the density of cold air is greater than that of hot air. When the cold air flows upward, convection can be formed, enabling the hot air to form a cycle upward, and the diffusion speed of the overall cold air is relatively fast. Therefore, in an embodiment of the utility model, the first direction is the horizontal direction, and the second direction is the vertical direction; the air outlet channel 14 is located above the installation area 15, and the air inlet channel 13 is located below the installation area 15. In this way, the cold air in the air inlet channel 13 enters the installation area 15 upward, then continues to enter the air outlet channel 14 upward and is discharged from the air outlet 12. The cold air diffuses faster in the box body 1, which is convenient to uniformly take away the heat from each heating element 4.

[0042] Please refer to Figure 3 and Figure 4 , the present utility model also proposes an electrical device 200, which includes a plurality of heating elements 4, a driving structure 3, and a box body structure 100. The specific structure of the box body structure 100 refers to the above-mentioned embodiment. Since this electrical device 200 adopts all the technical solutions of the above-mentioned all embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one. Among them, the plurality of heating elements 4 are correspondingly arranged in the plurality of installation sub-areas, and the driving structure's 3 function is to drive the air flowing into the box body 1 from the air inlet 11 to flow through the air inlet channel 13, the installation area 15, and the air outlet channel 14 and then be discharged from the air outlet 12.

[0043] In the technical solution of the present utility model, in this way, during the operation of the heating element 4, the driving structure 3 drives the air to flow. After the cold air enters the air inlet channel 13 in the box body 1 through the air inlet 11, it flows to the installation area ①5. Since the air inlet channel 13 extends along the first direction, when the cold air enters the installation area 15, it can enter each installation sub-area through the positions of the installation area 15 corresponding to the plurality of installation sub-areas, so as to dissipate heat from the heating elements 4 installed in each installation sub-area. After taking away the heat, the hot air passes through the air outlet channel 14 and is discharged from the air outlet 12; with such a setting, the overall structure enables the cold air to flow through each heating element 4 for heat dissipation, and the heat dissipation is more uniform.

[0044] In some embodiments, the driving structure 3 may be an air pump communicating with the air inlet 11 or the air outlet 12; in some embodiments, the driving structure 3 may be a fan module disposed on the housing 1 or outside the housing 1.

[0045] The housing structure 100 may be provided as one or multiple. In one embodiment, please refer to Figure 3 , the housing structure 100 is provided as multiple, and the multiple housing structures 100 are spaced apart in the second direction. By stacking the multiple housing structures 100, the space utilization rate is higher.

[0046] Furthermore, in one embodiment, please refer to Figure 3 , the air inlet 11 is disposed on one side of the housing 1 in the first direction, and the air inlet channel 13 is inclined towards the air inlet 11 in a direction away from the installation area 15 on the opposite side wall of the installation area 15; at least a part of one side wall of the housing 1 in the second direction is inclined to form the opposite side wall of the air inlet channel 13 and the installation area 15; the air outlet 12 is disposed on one side wall of the housing 1 in the second direction and opposite to the air inlet channel 13; the first direction is the horizontal direction, and the second direction is the vertical direction; the air outlet channel 14 is located above the installation area 15, and the air inlet channel 13 is located below the installation area 15; the fan module is located on the side opposite to the multiple housing structures 100 and the air inlet 11. With such a setting, when the multiple housing structures 100 are spaced apart in the second direction, when cold air enters the air inlet channel 13 from the air inlet 11, in addition to being able to change the cold air to flow from bottom to top, the inclined side wall of the air inlet channel 13, when the cold air is discharged from the air outlet 12, the inclined side wall of the housing 1 can change the movement of the hot air in the vertical direction to the horizontal direction, that is, the flow direction of the hot air can be changed to face the fan module, so that the fan module can quickly suck away the hot air, which can accelerate the overall air flow and has a better heat dissipation effect.

[0047] There are various types of the electrical equipment 200. For example, the electrical equipment 200 may be a power distribution cabinet, a transformer or a server. In one embodiment of the present invention, the electrical equipment 200 is provided as a server, and the corresponding multiple heating elements 4 include a backplane 42 and multiple hard disks 41.

[0048] In the related art, for the server, it further includes a power supply 4' and an expansion board. Please refer to Figure 1, the power supply 4' and the expansion board are usually placed in front of the multiple hard disks 2'. In order to allow the air flow to flow towards the multiple hard disks 2', it is necessary to stagger the power supply 4' from the multiple hard disks 2' to avoid the air flow, which will result in a low utilization rate of the overall space.

[0049] In the embodiment of the present invention, please refer to Figure 3 , the electrical device 200 further includes a power supply 5 and / or an expansion board 6. The power supply 5 and / or the expansion board 6 is located on one side of the multiple hard disks 41 in the first direction. The power supply 5 and / or the expansion board 6 does not block the air flow and can save space to place more of the hard disks 41. Among them, the power supply 5 and the expansion board 6 can be separately arranged on both sides or can be arranged on the same side; preferably, the power supply 5 and the expansion board 6 are arranged on the same side of the multiple hard disks 41 in the first direction and on the side opposite to the drive structure 3. In this way, while facilitating wiring, the installation space is saved.

[0050] The above is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
