Description

Technical Field

[0001] This application relates to the technical field of servers, and particularly to a heat dissipation and air guiding device. Background Art

[0002] In a server chassis, hard disks, as key components for data storage, are numerous and densely arranged. During the continuous operation of the server, the high-speed rotation of the hard disks generates a large amount of heat. If the heat cannot be dissipated in time, it will cause the temperature of the hard disks to be too high, which will in turn affect the data reading and writing speed. In severe cases, it may even cause hard disk failures and endanger data security.

[0003] In most of the air guiding structures of the heat dissipation devices in the related art, fixed shapes are adopted, which are only applicable to server chassis with specific shapes and sizes. After the internal space layout of the server chassis is adjusted, it will affect the normal use of the heat dissipation device, resulting in poor air guiding effect, making it difficult to effectively guide the air flow, and further leading to low heat dissipation efficiency of the hard disks and causing hard disk failures.

[0026] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0027] The embodiment of the present application provides a heat dissipation and diversion device, which is arranged in a server chassis to guide the air blown out by a heat dissipation fan to the hard disk for heat dissipation of the hard disk.

[0028] Specifically, as Figures 1 to 8 shown, the embodiment of the present application provides a heat dissipation and diversion device, including: An air guide cover 1, the air guide cover 1 includes a first mounting plate 11 and a second mounting plate 12 arranged oppositely. An installation space is formed between the first mounting plate 11 and the second mounting plate 12. The two sides of the installation space are open along a first direction, and the two sides of the installation space along the first direction are respectively corresponding to the heat dissipation fan and the hard disk. The two sides of the installation space are open along a second direction for fixing to the server chassis, and the second direction is perpendicular to the first direction.

[0029] As Figures 1 to 3 shown, in some embodiments of the present application, the heat dissipation and air guiding device further includes a channel adjusting assembly 2. The channel adjusting assembly 2 includes a first adjusting mechanism 21 and two sets of air collecting structures arranged at intervals. The two sets of air collecting structures are movably arranged between the first mounting plate 11 and the second mounting plate 12. That is to say, the two sets of air collecting structures are arranged in the installation space and can move along the second direction in the installation space. A wind guiding channel is formed between the two sets of air collecting structures and the first mounting plate 11 and the second mounting plate 12. The wind guiding channel is arranged along the first direction; the first adjusting mechanism 21 includes a first adjusting rod 211 and two driving plates 212 sleeved on the first adjusting rod 211. The axial direction of the first adjusting rod 211 is perpendicular to the first direction. That is to say, the first adjusting rod 211 is arranged along the second direction. The two driving plates 212 are respectively connected to the two sets of air collecting structures, and the two driving plates 212 can move linearly in opposite directions along the axial direction of the first adjusting rod 211. That is to say, the two driving plates 212 approach or move away from each other to drive the two air collecting structures to approach or move away from each other in opposite directions, so as to adjust the width of the wind guiding channel.

[0030] Exemplarily, the air collecting structures are hermetically connected to the first mounting plate 11 and the second mounting plate 12 respectively, so as to prevent the air flow from flowing out through the gaps between the air collecting structures and the first mounting plate 11 and between the air collecting structures and the second mounting plate 12. One end of the wind guiding channel is the air inlet side and the other end is the air outlet side. The air inlet side is arranged opposite to the heat dissipation fan, and the air outlet side is arranged opposite to the hard disk, so that the air blown out by the heat dissipation fan enters the wind guiding channel through the air inlet side and flows to the hard disk through the air outlet side.

[0031] Since the first adjusting rod 211 can drive the two driving plates 212 to move linearly in opposite directions, that is, approach or move away from each other, when the first adjusting rod 211 moves, it can further drive the two air collecting structures to approach or move away from each other, so as to adjust the width of the wind guiding channel formed between the two air collecting structures. Furthermore, the widths of the air inlet side and the air outlet side of the wind guiding channel can be adjusted according to different specifications of the server chassis. When used in cooperation with different specifications of server chassis, good air guiding effects can be produced, and then the air flow can be effectively guided to timely and effectively dissipate the heat of the hard disk, avoiding the failure problems caused by the high temperature of the hard disk. The heat dissipation and air guiding device is applicable to different specifications of server chassis, reducing the troubles and cost problems brought by the need to customize different heat dissipation and air guiding devices due to the differences in the specifications of the server chassis. The operation is simple, improving the versatility and adaptability of the heat dissipation and air guiding device.

[0032] In some embodiments of the present application, the width of the air guiding channel gradually increases in a direction away from the first adjusting rod 211. Specifically, the air guiding channel is located on one side or both sides of the first adjusting rod 211. When the air guiding channel is located on one side of the first adjusting rod 211, the end of the air guiding channel away from the first adjusting rod 211 is the air inlet side, and the width of the air guiding channel at the air inlet side is the largest. Along the air flow direction, the width of the air guiding channel gradually decreases; when the air guiding channel is located on both sides of the first adjusting rod 211, one end of the air guiding channel is the air inlet side and the other end is the air outlet side. Along the air flow direction, the width of the air guiding channel first gradually decreases and then gradually increases. By setting the width of the air inlet side of the air guiding channel to be relatively large, a relatively large range of air flow can be collected, so that the air blown out by the cooling fan can enter the air guiding channel through the air inlet side as much as possible, avoiding waste of air volume and improving the heat dissipation efficiency of the hard disk.

[0033] In some embodiments of the present application, the air collecting structure includes an air collecting plate 22. The included angle between the air collecting plate 22 and the axial direction of the first adjusting rod 211 is an acute angle. One end of the air collecting plate 22 is connected to the driving plate 212. An air guiding channel is formed between the driving plate 212, the air collecting plate 22, the first mounting plate 11, and the second mounting plate 12. The number of air collecting plates 22 is one or two. When the number of air collecting plates 22 is one, the air collecting plate 22 is disposed on one side of the first adjusting rod 211. The two air collecting plates 22 of the two air collecting structures are oppositely arranged on the same side of the first adjusting rod 211. The included angle between the air collecting plate 22 and the axial direction of the first adjusting rod 211 is an acute angle. Therefore, the width of the air guiding channel formed between the two air collecting plates 22 of the two air collecting structures gradually increases in a direction away from the first adjusting rod 211.

[0034] In some embodiments of the present application, each set of air collecting structures includes two air collecting plates 22, which are respectively arranged on both sides of the first adjusting rod 211. The angles between the two air collecting plates 22 and the axial direction of the first adjusting rod 211 can be the same or different. When the angles between the two air collecting plates 22 and the axial direction of the first adjusting rod 211 are the same, the two air collecting plates 22 are symmetrically arranged with respect to the first adjusting rod 211. The angles between the two air collecting plates 22 and the axial direction of the first adjusting rod 211 can also be different, so that one air collecting plate 22 is arranged corresponding to the cooling fan, and the other air collecting plate 22 is arranged corresponding to the hard disk. Exemplarily, the two air collecting plates 22 in each set of air collecting structures are respectively the first air collecting plate and the second air collecting plate. The first air collecting plate and the second air collecting plate are arranged on both sides of the first adjusting rod 211, and the angle α between the first air collecting plate and the axial direction of the first adjusting rod 211 is equal to the angle β between the second air collecting plate and the axial direction of the first adjusting rod 211. The ends of the two first air collecting plates away from the first adjusting rod 211 form the air inlet side of the air guiding channel, and the ends of the two second air collecting plates away from the first adjusting rod 211 form the air outlet side of the air guiding channel. The widths of the air inlet side and the air outlet side are equal. When α and β are not equal, the width of the air inlet side is not equal to the width of the air outlet side. Specifically, the widths of the air inlet side and the air outlet side are related to the sizes of the cooling fan and the hard disk. That is to say, the size of the angle between the first air collecting plate and the first adjusting rod 211 is related to the size of the cooling fan, and the size of the angle between the second air collecting plate and the first adjusting rod 211 is related to the size of the hard disk.

[0035] Combined with Figure 5 and Figure 6 As shown, in some embodiments of the present application, a first slider 221 is provided on the first side surface and / or the second side surface of the air collecting plate 22, and a first sliding groove 112 is provided at the corresponding position of the first mounting plate 11 and / or the second mounting plate 12. The first slider 221 is slidably arranged in the first sliding groove 112.

[0036] Specifically, the first side surface of the air collecting plate 22 is the side surface of the air collecting plate 22 opposite to the first mounting plate 11, and the second side surface of the air collecting plate 22 is the side surface of the air collecting plate 22 opposite to the second mounting plate 12. The first slider 221 is in sliding fit with the first sliding groove 112. On the one hand, it can realize the sliding fit between the air collecting plate 22 and the first mounting plate 11 and the second mounting plate 12. On the other hand, it can guide the moving path of the air collecting plate 22.

[0037] In some embodiments of the present application, the air collecting plate 22 is rotatably connected to the driving plate 212, and the first sliding is rotatably arranged on the first side surface, and the first sliding groove 112 is arranged in parallel with the air collecting plate 22. When the air collecting plate 22 moves along with the driving plate 212, the first slider 221 slides along the first sliding groove 112, forcing the air collecting plate 22 to rotate around the hinge point with the driving plate 212, so as to change the inclination angle and width of the air guiding channel.

[0038] Specifically, as Figure 4 shown, the first side and / or the second side of the air collecting plate 22 bulge outwards to form a first pin 223, and the first slider 221 is rotatably mounted on the first pin 223. Both sides of the air collecting plate 22 are slidably connected to the first mounting plate 11 and the second mounting plate 12 through the matching structure of the first slider 221 and the first chute 112. A sealing arrangement is provided between the first side of the air collecting plate 22 and the first mounting plate 11, and between the second side of the air collecting plate 22 and the second mounting plate 12, so as to ensure that there is no gap between the air collecting plate 22 and the first mounting plate 11 and the second mounting plate 12 during the movement of the air collecting plate 22, preventing air leakage.

[0039] In some embodiments of the present application, in order to prevent the first slider 221 from disengaging from the first chute 112, a limiting groove is provided on the side wall of the first chute 112, and a limiting block is correspondingly provided on the side surface of the first slider 221. When the first slider 221 is mounted in the first chute 112, the limiting block is correspondingly arranged in the limiting groove and can slide in the limiting groove, improving the stability of the mounting structure of the air collecting plate 22 with the first mounting plate 11 and the second mounting plate 12.

[0040] In some embodiments of the present application, a flexible sealing member 23 is connected between the air collecting plate 22 and the driving plate 212 to achieve a sealed connection between the air collecting plate 22 and the driving plate 212. Exemplarily, the flexible sealing member 23 is an arc-shaped plate structure made of a flexible material. One end of the flexible sealing member 23 is connected to the driving plate 212, and the other end is connected to the air collecting connection, enabling the air collecting plate 22 to rotate by a certain angle to adjust the inclination angle of the air collecting plate 22. At the same time, the flexible sealing member 23 seals the gap between the driving plate 212 and the air collecting plate 22, preventing air leakage. The flexible sealing member 23 serves a dual role of a hinge and a baffle.

[0041] In some embodiments of the present application, a leakage prevention extrusion column 222 is provided at one end of the air collecting plate 22 away from the first adjusting rod 211, and the leakage prevention extrusion column 222 is made of an elastic material. Specifically, during use, the leakage prevention extrusion column 222 fits against the inner wall of the server chassis, further ensuring the sealing of the air guiding channel.

[0042] In some embodiments of the present application, a first threaded section 2111 and a second threaded section 2112 are provided on the first adjusting rod 211. The spiral directions of the first threaded section 2111 and the second threaded section 2112 are opposite. The two driving plates 212 are provided with driving portions, and the driving portions are provided with threaded holes and are respectively connected to the first threaded section 2111 and the second threaded section 2112 through the threaded holes. By rotating the first adjusting rod 211, the driving plates 212 move along the first adjusting rod 211.

[0043] Exemplarily, the driving part may include a threaded connector and a moving sleeve. The threaded connectors on the two driving parts are respectively engaged with the first threaded section 2111 and the second threaded section 2112. The moving sleeve is rotatably sleeved on the threaded connector, and relative rotation can occur between the moving sleeve and the threaded connector in the circumferential direction, and they are relatively fixed in the axial direction. When the first adjusting rod 211 rotates, driving the two threaded connectors to be respectively engaged with the first threaded section 2111 and the second threaded section 2112, it will drive the two threaded connectors to rotate around the circumference of the first adjusting rod 211 while moving in the opposite direction along the axial direction of the first adjusting rod 211. The moving sleeve and the threaded connector can rotate relative to each other but cannot move relative to each other in the axial direction. Thus, while the threaded connector moves, it will drive the moving sleeve to move linearly along the axial direction of the first adjusting rod 211, and the two moving sleeves move linearly in opposite directions to make the two moving sleeves approach or move away from each other.

[0044] By rotating the first adjusting rod 211, it is possible to simultaneously drive the two moving sleeves to move linearly in opposite directions, and then drive the two groups of air collecting structures to move linearly in opposite directions to adjust the width of the air guiding channel. The structure is simple and the operation is convenient.

[0045] In some embodiments of the present application, a first installation channel extending along the second direction is provided inside the first installation plate 11. The first adjusting rod 211 is rotatably inserted into the first installation channel. The first installation channel extends from one side surface of the first installation plate 11 along the second direction to the other side surface, and the first end of the first installation channel is formed on one side surface of the second installation plate 12 along the second direction. The second end of the first installation channel is located inside the first installation plate 11. The second end of the first adjusting rod 211 is inserted into the first installation channel, and the second end of the first adjusting rod 211 is rotatably connected to the second end of the first installation channel. The first end of the first adjusting rod 211 is located outside the first installation channel to form a first knob 211a for operating the rotation of the first adjusting rod 211.

[0046] On the side wall of the first mounting plate 11 facing the second mounting plate 12, a second sliding groove 111 is provided throughly. The second sliding groove 111 is in the same extending direction as and communicates with the first mounting channel. The driving part of the driving plate 212 passes through the second sliding groove 111 and is respectively threadedly connected to the first threaded section 2111 and the second threaded section 2112. The number of the second sliding grooves 111 is two. The two second sliding grooves 111 are respectively arranged corresponding to the first threaded section 2111 and the second threaded section 2112. The driving part on the driving plate 212 is slidably arranged in the second sliding groove 111, driving the air collecting structure to move linearly, thereby changing the width of the air guiding channel formed between the two air collecting structures. The setting of the second sliding groove 111 plays a guiding role for the moving path of the driving plate 212, so that the driving plate 212 can only move linearly and cannot rotate. By the sliding fit between the end of the driving plate 212 far from the driving part and the second mounting plate 12, the rotation of the driving plate 212 is also restricted.

[0047] In some embodiments of the present application, a positioning rod 24 is provided on the side of the driving plate 212 facing away from the air guiding channel. The positioning rod 24 is arranged along the axial direction of the first adjusting rod 211, and an anti-slip positioning part 241 is provided at the end of the positioning rod 24 far from the driving plate 212. When the first adjusting rod 211 rotates, it drives the driving plate 212 and the air collecting plate 22 to move synchronously. Furthermore, the positioning rod 24 will also move accordingly. During use, according to the size of the server chassis, the distance between the two driving plates 212 is adjusted so that the anti-slip positioning part 241 on the positioning rod 24 abuts against the side wall of the server chassis, enabling the heat dissipation and air guiding device to be installed in the server chassis.

[0048] In some embodiments of the present application, the air guiding cover 1 further includes a support member 13. The support member 13 is supported and connected between the first mounting plate 11 and the second mounting plate 12, and a through hole 131 is provided on the support member 13. The positioning rod can slidably pass through the through hole 131. Exemplarily, the number of the support members 13 is two. The support members 13 are arranged opposite to the side of the driving plate 212 facing away from the air guiding channel. Each support member 13 corresponds to two positioning rods, and two through holes 131 are provided on the support member 13. The two corresponding positioning rods 24 pass through the two through holes 131. The cooperation between the positioning rod and the through hole 131 plays a guiding role for the moving path of the driving plate 212, ensuring the stable operation of the driving plate 212.

[0049] As shown in the figure, in some embodiments of the present application, the heat dissipation and air guiding device further includes an air guiding adjustment assembly 3. The air guiding adjustment assembly 3 is at least provided on the air outlet side of the air guiding channel. That is to say, the air guiding adjustment assembly 3 is provided on the air outlet side of the air guiding channel, or the air guiding adjustment assembly 3 is provided on the air outlet side and the air inlet side of the air guiding channel.

[0050] The air guiding and adjusting component 3 is adjusted according to the size of the hard disk. Specifically, the air guiding and adjusting component 3 includes a second adjusting mechanism and multiple partition plates 32 connected to the second adjusting mechanism. The multiple partition plates 32 are arranged at intervals along the width direction of the air guiding channel. The second adjusting mechanism is connected to the multiple partition plates 32 and is used to drive the multiple partition plates 32 to move synchronously, so that the multiple partition plates 32 gather or disperse with each other. The space between two adjacent partition plates 32 corresponds to one hard disk. By equidistantly adjusting the distance between adjacent partition plates 32 through the second adjusting mechanism, the multiple partition plates 32 can gather or disperse with each other, adapting to hard disks of different widths, making the space between two adjacent partition plates 32 exactly face one hard disk, and improving the air guiding effect.

[0051] During use, the second adjusting mechanism is located between the air outlet of the air guiding channel and the partition plate 32, and the end face of the partition plate 32 away from the second adjusting mechanism abuts against the joint of two adjacent hard disks.

[0052] In some embodiments of the present application, the second adjusting mechanism includes multiple connecting rods 31, a foldable mechanism, and a driving mechanism. The multiple connecting rods 31 are respectively connected to the multiple partition plates 32 correspondingly. Third sliders 36 are provided at both ends of the connecting rod 31. Multiple third chutes 113 are arranged at intervals along the width direction of the air guiding channel on the first mounting plate 11 and the second mounting plate 12. The third chutes 113 extend along the second direction. The third sliders 36 are slidably arranged in the third chutes 113. The driving mechanism is connected to at least one third slider 36 and drives the third slider 36 to slide in the third chutes 113. A set of foldable structures is arranged between two adjacent connecting rods 31. The two ends of the foldable structure are respectively rotatably connected to the two connecting rods 31. The foldable structure can be folded or unfolded along the width direction of the air guiding channel to drive the multiple partition plates 32 to gather or disperse with each other.

[0053] Exemplarily, the number of the connecting rods 31 is equal to the number of the partition plates 32, and they are connected in a one-to-one correspondence. The foldable mechanism is connected to the inner side surface of the connecting rod 31, and the partition plate 32 is connected to the outer side surface of the connecting rod 31. Herein, the inner side surface of the connecting rod 31 is the side of the connecting rod 31 facing the air guiding channel, and the outer side surface of the connecting rod 31 is arranged opposite to the inner side surface. The driving mechanism includes a second adjusting rod 35. A third threaded section is provided on the second adjusting rod 35. A second installation channel is arranged on the first installation plate 11 or the second installation plate 12 along the second direction. The second installation channel communicates with a third sliding groove 113 at the outermost edge. The second end of the second adjusting rod 35 is rotatably inserted into the second installation channel and the third sliding groove 113. The first end of the second adjusting rod 35 is located in the second installation channel, and the second end of the second adjusting rod 35 forms a second knob 351 for operating and rotating the second adjusting rod 35. A threaded hole is provided on the third slider 36, and the third slider 36 is connected to the third threaded section through the threaded hole. By rotating the second adjusting rod 35, the third slider 36 moves along the axial direction of the second adjusting rod 35. The third sliding groove 113 guides the movement of the third sliding groove 113, restricting the rotation of the third slider 36 and ensuring that the third slider 36 can only move in a straight line. Furthermore, the connecting rod 31 connected to the third slider 36 moves in a straight line with the third slider 36, driving the shape of the foldable structure to change, pushing the adjacent connecting rods 31 and the foldable mechanism to move, and further causing the multiple connecting rods 31 to gather or disperse from each other. A sub-channel is formed between adjacent partition plates 32. The gathering or dispersing of the multiple connecting rods 31 synchronously and equally changes the width of each sub-channel to adapt to different hard disk widths.

[0054] In some embodiments of the present application, the foldable structure includes two connecting rods 33 connected by rotation. The two connecting rods 33 are connected in a V shape between two adjacent connecting rods 31, and the ends of the connecting rods 33 are rotatably connected to the connecting rods 31. The V-shaped openings of two adjacent sets of foldable structures are arranged in opposite directions.

[0055] Specifically, a connecting column 34 is formed on the inner side surface of the connecting rod 31. The end of the connecting rod 33 is rotatably connected to the connecting column 34. The two connecting rods 33 in each set of foldable structures are rotatably connected. The connecting rods 33 of multiple sets of foldable structures are connected end to end to form a parallel four-bar linkage 33 mechanism. When the leftmost third slider 36 moves in the third sliding groove 113, the connecting rod 31 connected to the third slider 36 will push the connecting rod 33 connected to it to move, and further will push the remaining connecting rods 31 to move synchronously and equally, realizing the equal-distance adjustment between multiple partition plates 32.

[0056] In some embodiments of the present application, air guide plates 14 are provided on at least one side of the first mounting plate 11 along the first direction, second air guide plates are provided at corresponding positions of the second mounting plate 12, a partition plate 32 is arranged between the first air guide plate and the second air guide plate, and the partition plate 32 is connected to the corresponding connecting rod 31 through an elastic member 37, so that when the partition plate 32 moves in the second direction, the end faces at both ends of the partition plate 32 are respectively attached to the first air guide plate and the second air guide plate.

[0057] Exemplarily, as Figure 8 shown, an installation space for the connecting rod 31 and an installation space for the partition plate 32 are formed between the third slider 36 on the first mounting plate 11 and the correspondingly arranged third slider 36 on the second mounting plate 12. Both ends of the connecting rod 31 are respectively connected to two oppositely arranged third sliders 36. The partition plate 32 is located outside the connecting rod 31, and the partition plate 32 includes a first connecting section and a second connecting section. The end faces at both ends of the first connecting section are respectively in sliding fit with two corresponding third sliders 36, and the end faces at both ends of the second connecting section are respectively arranged corresponding to the first air guide plate and the second air guide plate. The first connecting section is movably arranged between two correspondingly arranged third sliders 36 along the first direction, and the inner side of the first connecting section is connected to the outer side surface of the connecting rod 31 through an elastic member 37. In some embodiments of the present application, the elastic member 37 is a strong spring. The purpose of such a setting is to make the end faces at both ends of the second connecting section of the partition plate 32 be respectively attached to the first air guide plate and the second air guide plate when the partition plate 32 moves along with the connecting rod 31.

[0058] During use, the elastic member 37 is always in a stretched state, generating a continuous restoring force. Under the action of the restoring force of the elastic member 37, the partition plate 32 tightly presses against the inner side walls of the first air guide plate and the second air guide plate. A seamless seal is formed between the partition plate 32 and the first air guide plate and the second air guide plate, improving the sealing effect between adjacent sub-channels, and thus improving the flow guiding effect.

[0059] The heat dissipation and diversion device according to the embodiment of the present application can be installed by rotating the first knob 211a to adjust the position of the anti-slip positioning portion 241 to squeeze the inner wall of the server. It can adapt to server chassis of different widths, improve the versatility and adaptability of the product, and reduce the trouble and cost of customizing different heat dissipation devices due to differences in server specifications. Compared with the traditional complex installation method, the operation is more simple and fast, saving installation time and labor costs. The channel adjustment component 2 can adaptively change the angle and position of the air collecting plate 22 according to the movement of the driving plate 212 and the action of the first sliding groove 112. At the same time, the flexible seal 23 and the anti-leakage extrusion column 222 ensure the airtightness of air conduction, can better adapt to the complex structure and different spatial layouts inside the server chassis, effectively guide the air flow, and improve the heat dissipation efficiency. By rotating the second knob 351, the equal-distance adjustment of the partition plate 32 can be realized, which is convenient to align the partition plate 32 with the edge of the hard disk, reasonably divide the heat dissipation space of the hard disk, so that each hard disk can have a relatively independent and appropriate sub-channel, avoid the mutual interference of heat between hard disks, and further improve the overall heat dissipation effect of the hard disks.

[0060] The above has introduced in detail a heat dissipation and diversion device provided by the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
