[0044] 1. The wind deflection assembly provided by the embodiments of the present application can adapt to heat dissipation assemblies in different heat dissipation scenarios, and can be combined by the first wind deflector and the second wind deflector to form wind deflection assemblies of different lengths to adapt to different heat dissipation scenarios, thereby avoiding the design of different production molds for wind deflection assemblies, reducing the cost of production molds, improving the reuse rate of wind deflector accessories, thereby reducing the development and manufacturing cost of wind deflectors and reducing production cost.

[0045] 2. The wind deflection assembly provided by the embodiments of the present application, the design of the first support block in the sub-assembled wind deflector one and the second support block in the sub-assembled wind deflector two can form a mutual support structure when the support blocks are connected with the corresponding ventilation assemblies, and the connection is fastened and stable, which can effectively prevent the corresponding components from deforming after being heated during the heat dissipation process, and prevent the connection components from being misaligned on the butt joint surface, thereby breaking the technical prejudice that the splicing structure in the prior art is not strong enough, is easy to fall off, and is misaligned, and in the effect experiment, the experimental results of the splicing structure and the overall structure are basically the same.

[0046] 3、The wind guide assembly provided by the embodiment of the present application connects the first wind guide cover and at least one second wind guide cover through the clamping piece, replaces the original whole wind guide structure, and has a wind guide effect basically equivalent to the whole structure. In the wind guide simulation experiment, when the upper part of the first wind guide cover is not provided with the remaining heat dissipation components, the front air inlet can be blocked by the baffle to prevent air flow from entering the upper part of the first wind guide cover.

For the upper part of the wind guide cover, the wind guide speed ratio of the spliced structure to the whole structure is 98:100, and the wind guide volume ratio of the spliced structure to the whole structure is 98:100. In actual application, the heat dissipation device composed of the wind guide assembly and the heat dissipation assembly can effectively dissipate heat for the heat dissipation components.

[0047] 4、The wind guide assembly provided by the embodiment of the present application can block the front air inlet when the wind guide assembly is not needed to guide air flow on the upper part, so as to prevent air flow from entering the upper part of the wind guide assembly and improve the air collection effect of the lower part of the wind guide assembly. When the wind guide assembly is needed to guide air flow on the upper part, the baffle can be removed to dissipate heat for the heat dissipation components behind the wind guide assembly, and air can be collected and sent flexibly.

[0048] 5、The wind guide assembly provided by the embodiment of the present application can form a high-low structure through the design of the first protruding part, the first recessed part, the corresponding second protruding part and the second recessed part, so as to effectively reduce the occupation of the internal space of the heat dissipation device by the whole wind guide assembly. Meanwhile, the high-low structure can increase the structural strength of the wind guide assembly. BRIEF DESCRIPTION OF DRAWINGS

[0064] It should also be understood that the terms "first", "second" and the like are only for descriptive purposes and should not be construed as indicating or implying relative importance.

[0065] Embodiment one

[0066] The present application provides a wind guide assembly, referring to Figure 1 , the wind guide assembly comprises: a first wind guide cover 1 and at least one second wind guide cover 2. Wherein, the first wind guide cover 1 and the second wind guide cover 2 are connected to adapt to the heat dissipation assembly.

[0067] Specifically, the heat dissipation assembly can be applied in the scene including server, computer and switch and other heat dissipation assemblies. The wind guide assembly structure can be configured above the heat dissipation assembly radiator. Since there are cables on the top of the wind guide cover, the cables are not suitable for direct contact with the radiator, so a long wind guide assembly is needed to assist the wind cooling. At the same time, since different servers or switches require different radiators, different heat dissipation scenes need to adapt to the wind guide assembly. A fixed length of the first wind guide cover 1 and a plurality of second wind guide cover 2 extension pieces can be combined to form different wind guide assemblies to adapt to different heat dissipation scenes. A second wind guide cover 2 is added behind the first wind guide cover 1. The number of second wind guide covers is not equal. This combination replaces the original different specifications of the fixed form of the wind guide cover, thereby avoiding the production of different wind guide cover molds, reducing the cost of production molds, improving the reuse rate of wind guide cover accessories, and thereby reducing the manufacturing cost of the wind guide cover. The connection mode of the first wind guide cover 1 and the second wind guide cover 2 can be splicing, clamping, hinging or docking assembly connection mode, which is not limited here. In subsequent embodiments, the clamping mode is described in detail.

[0068] In some embodiments, the second wind guide cover 2 comprises a sub-assembled wind guide cover two 22, and the first wind guide cover 1 is clamped with the sub-assembled wind guide cover two 22.

[0069] In some embodiments, the second wind deflector 2 comprises at least one sub-assembly wind deflector one 21. After all the sub-assembly wind deflectors one 21 are connected to each other, the first sub-assembly wind deflector one 21 is connected to the first wind deflector 1.

[0070] In some embodiments, the second wind deflector 2 further comprises at least one sub-assembly wind deflector one 21 and one sub-assembly wind deflector two 22. After all the sub-assembly wind deflectors one 21 are connected to each other, the first and last sub-assembly wind deflectors one 21 are connected to the first wind deflector 1 and the sub-assembly wind deflector two 22, respectively.

[0071] Specifically, the set of wind deflector components requires three sets of molds, corresponding to the first wind deflector 1, the sub-assembly wind deflector one 21, and the sub-assembly wind deflector two 22, respectively. If the overall assembled wind deflector length required by the heat dissipation scene is not long, and only one second wind deflector 2 is needed, the sub-assembly wind deflector two 22 can be assembled by corresponding connection with the first wind deflector 1. If multiple second wind deflectors 2 are required by the heat dissipation scene, for example, N second wind deflectors 2, then N-1 sub-assembly wind deflectors one 21 and one sub-assembly wind deflector two 22 can be included, where N is greater than or equal to 2. Among them, N-1 sub-assembly wind deflectors one 21 are connected to each other as a small whole, and the head and tail of the sub-assembly wind deflector one 21 are connected to the first wind deflector 1 and the sub-assembly wind deflector two 22, respectively, to form the assembled wind deflector as a whole. The abutting surfaces of the second wind deflector 2 and the first wind deflector 1 are connected by an abutting assembly except for the edge part. In particular, N second wind deflectors 2 can also be sub-assembly wind deflectors one 21, that is, N sub-assembly wind deflectors one 21 are included, and the first sub-assembly wind deflector one 21 is connected to the first wind deflector 1 after all the sub-assembly wind deflectors one 21 are connected to each other.

[0072] For example, the first wind deflector 1 corresponds to a conventional heat sink, and the second wind deflector 2 corresponds to the additional part compared to the conventional heat sink, thereby realizing the coverage of the first wind deflector 1 and the second wind deflector 2 on the overall heat sink of the heat dissipation device. By separately processing and producing the first wind deflector 1, the sub-assembly wind deflector one 21, and the sub-assembly wind deflector two 22, instead of using an integrated wind deflector, only three molds are needed to meet the production needs of all wind deflectors. Due to the small area of the second wind deflector 2, the cost of opening a mold for the second wind deflector 2 is reduced. Since the first wind deflector 1 is a basic accessory corresponding to the conventional heat sink, it will be used regardless of the type of heat sink it is applied to, which can improve the reuse rate of the first wind deflector 1 and effectively reduce the production cost of the first wind deflector 1 in batch production. The two are connected by the abutting assembly except for the edge part, increasing the contact area and connection strength of the two.

[0073] In some embodiments, the first wind deflector 1 comprises a first baffle 13, the first baffle 13 is provided with at least one first ventilation assembly 131, and the first baffle 13 is further provided with a first locking hole 132; the second wind deflector 2 comprises a locking column 25, and the second wind deflector 2 is clamped with the first wind deflector 1 through the locking column 25 and the first locking hole 132.

[0074] In some embodiments, the sub-assembled wind deflector two 22 comprises a second baffle 221, the second baffle 221 is connected with a second supporting block 222, and the second supporting block 222 is clamped with the first ventilation assembly 131.

[0075] In some embodiments, when the number of the second wind deflectors 2 is two or more, the sub-assembled wind deflector one 21 comprises a second ventilation assembly 211 and a second locking hole 213, the second ventilation assembly 211 is connected with a first supporting block 212; when the sub-assembled wind deflector one 21 is connected with the first wind deflector 1, the first supporting block 212 passes through the first ventilation assembly 131 to be clamped, and the sub-assembled wind deflector one 21 is clamped with the first wind deflector 1 through the locking column 25 and the first locking hole 132; when the sub-assembled wind deflector one 21 is connected with another sub-assembled wind deflector one 21, the sub-assembled wind deflector one 21 passes through the second ventilation assembly 211 of the other sub-assembled wind deflector one 21 through the first supporting block 212 to be clamped, and the sub-assembled wind deflector one 21 is clamped with the other sub-assembled wind deflector one 21 through the locking column 25 and the second locking hole 213; when the sub-assembled wind deflector one 21 is connected with the sub-assembled wind deflector two 22, the sub-assembled wind deflector two 22 passes through the second ventilation assembly 211 through the second supporting block 222 to be clamped, and the sub-assembled wind deflector two 22 is clamped with the sub-assembled wind deflector one 21 through the locking column 25 and the second locking hole 213.

[0076] Specifically, referring to Figure 2 When the number of the second wind deflectors 2 is one, the second wind deflector 2 is the sub-assembled wind deflector two 22. The sub-assembled wind deflector two 22 comprises a second baffle 221, the second baffle 221 is connected with a second supporting block 222, and the second supporting block 222 of the sub-assembled wind deflector two 22 is clamped with the first ventilation assembly 131 of the first wind deflector 1. Referring to Figure 3 and Figure 4 When the number of the second wind deflectors 2 is more than one, taking the number of the second wind deflectors 2 as four in the drawings as an example, which comprises three sub-assembled wind deflectors one 21 and one sub-assembled wind deflector two 22, the sub-assembled wind deflector one 21 comprises a second ventilation assembly 211 and a second 213, and the second ventilation assembly 211 is connected with a first supporting block 212. Referring to Figure 4 and Figure 5, first three sub-assembly wind scoops one 21 are connected with each other, the latter sub-assembly wind scoops one 21 are clamped through the first support block 212 through the second ventilation assembly 211 of the former sub-assembly wind scoops one 21, and are clamped with the former sub-assembly wind scoops one 21 through the locking column 25 and the second locking hole 213 cooperation.The first sub-assembly wind scoops one 21 and the first wind scoops 1 are connected when three sub-assembly wind scoops one 21 are clamped and assembled, the first sub-assembly wind scoops one 21 are clamped through the first support block 212 through the first ventilation assembly 131 of the first wind scoops 1, and are clamped with the first wind scoops 1 through the locking column 25 and the first locking hole 132 cooperation.Then, the last sub-assembly wind scoops one 21 and the sub-assembly wind scoops two 22 are connected, and the sub-assembly wind scoops two 22 are clamped through the second support block 222 through the second ventilation assembly 211, and are clamped with the sub-assembly wind scoops one 21 through the locking column 25 and the second locking hole 213 cooperation.In this way, the assembly of the wind guide assembly is completed.It should be noted that the above assembly process of the wind guide assembly is only an example, and the number of sub-assembly wind scoops one 21 is not limited to three, and the corresponding number can be selected according to the actual heat dissipation length.In addition, the installation sequence is also only an example, and the first wind scoops 1 can be installed first or the sub-assembly wind scoops two 22 can be installed first, and the assembly is flexible, and the actual scene can be flexibly selected.The first ventilation assembly 131 and the second ventilation assembly 211 can be ventilation holes or ventilation grilles and other components with ventilation function;In addition, the locking column 25 can also be a structure of a docking column or a clamping column and a to-be-connected component matched with each other;Similarly, the first locking hole 132 and the second locking hole 213 can be corresponding to a docking hole or a clamping buckle, a clamping hole and other structure forms to realize the corresponding matching connection mode.It should be noted that the first support block 212 and the second support block 222 have the same structure, and the first support block 212 and the second support block 222 form a mutual support structure with the first ventilation assembly 131 and the second ventilation assembly 211, which is clamped and fastened stably, and can effectively avoid the deformation of each component after being heated during heat dissipation;The first support block 212 and the second support block 222 can be hollow structures to facilitate simultaneous auxiliary air guide.

[0077] In some embodiments, the first wind scoops 1 include first protrusions 11 and first recesses 12, and the second wind scoops 2 include second protrusions 23 and second recesses 24 corresponding to the first protrusions 11 and the first recesses 12, respectively.

[0078] Specifically, referring to Figure 2The top surface of the first air guide cover 1 is provided with a first protruding part 11 and a first recessed part 12, wherein the first protruding part 11 and the first recessed part 12 can be arranged at intervals. In some heat dissipation scenarios, the first protruding part 11 can correspond to the heat sink, and the first recessed part 12 can correspond to the memory bar. Similarly, the top surface of the second air guide cover 2 is provided with a second protruding part 23 and a second recessed part 24 corresponding to the first protruding part 11 and the first recessed part 12, respectively. The abutting surfaces of the first recessed part 12 and the second recessed part 24 are connected through the abutting assembly. By corresponding the first protruding part 11 and the first recessed part 12 to the heat sink and the memory bar, respectively, a high-low relief surface structure is formed, which effectively reduces the occupation of the air guide assembly on the internal space of the heat dissipation device, and at the same time, the high-low relief structure increases the structural strength of the air guide assembly to a certain extent; the abutting surfaces of the first recessed part 12 and the second recessed part 24 are connected, and the air vents of the first protruding part 11 corresponding to the heat sink are reasonably avoided, so as to realize the reasonable connection of the abutting surfaces.

[0079] For example, the CPU consumes a large amount of heat and needs a large amount of heat dissipation, and the heat dissipation of the heat sink on the CPU is also relatively high. Therefore, when designing, it is necessary to consider that the air volume passes through the CPU heat sink as much as possible. Referring to Figure 10 W1 is the width of the CPU heat sink position, W2 is the width of the memory bar position, and W3 is the width of the memory bar to the edge of the air guide assembly. The calculation formula of the proportion of the convex part corresponding to the entire air guide assembly is:

[0080]

[0081] Wherein, n1 is the number of CPU heat sink positions, n2 is the number of memory bar positions, and n3 is the number of memory bar to air guide assembly edge positions. For example, referring to Figure 10 n1=2, n2=4, and n3=2. Generally, the proportion of the convex part is between 37% and 39%.

[0082] In some embodiments, a plurality of reinforcing rib protrusions 121 are arranged on the first recessed part 12, the reinforcing rib protrusions 121 are separated by air passages 122 and empty grooves 124, and a partition plate 123 is further arranged on the first recessed part 12.

[0083] Specifically, the inner wall of the first recessed part 12 is provided with reinforcing rib protrusions 121 at intervals. The reinforcing rib protrusions 121 are divided into air passing channels 122 and empty grooves 124. When there is only a conventional radiator, the installation space of a graphics processor can be provided at the rear of the first air guide cover 1. The graphics processor or other components requiring heat dissipation are installed at the rear of the overall air guide assembly. The air passing channels 122 can be used to dissipate heat. When the graphics processor or other components are installed, air can pass through the air passing channels 122, and the air flow is guided by the first air vent assembly 131 and the second air vent assembly 211 to achieve cooling of the graphics processor during use.

[0084] In some embodiments, the first recessed part 12 is further provided with a wind shield 14.

[0085] Specifically, the first recessed part 12 is further provided with a wind shield 14 away from the second air guide cover 2. When no other components requiring heat dissipation (such as the graphics processor mentioned above) are installed at the rear of the first air guide cover 1, the front air vent can be blocked by the wind shield 14 to prevent air flow from entering the upper part of the first air guide cover 1, thereby reducing the amount of air entering the first air guide cover 1.

[0086] In some embodiments, the sub-assembled air guide cover 1 21 further comprises a baffle 214.

[0087] Specifically, referring to Figure 6 and Figure 7 , the baffle 214 is arranged in the second recessed part 12. When components such as graphics processors are installed at the rear of the first air guide cover 1 or the overall air guide assembly, referring to Figure 7 , the wind shield 14 can be opened to avoid blocking the front air vent assembly, so that air flow enters the upper part of the first air guide cover 1 and passes through the air passing channels 122, and the air flow is guided by the first air vent assembly 131 and the second air vent assembly 211 to achieve cooling of the graphics processor during use. At the same time, due to the presence of the partition 123 and the baffle 214, the air flow between the first air vent assembly 131 and the second air vent assembly 211 is collected, further improving the cooling effect of the graphics processor and other components. It should be noted that, in order to ensure the cooling effect of the components on the first air guide cover 1, referring to Figure 7 , only the sub-assembled air guide cover 1 21 and the first air guide cover 1 can be assembled to make the air flow pass through the second air vent assembly 211 and be discharged from the overall assembled air guide cover, thereby dissipating heat from the graphics processor and other components at the rear of the overall air guide cover. When there are no components installed at the rear of the first air guide cover 1, referring to Figure 6The front air vent assembly can be blocked by the baffle 14 to prevent air flow into the upper part of the first air deflector 1, thereby reducing the amount of air entering the first air deflector 1. At this time, the first air deflector 1, the sub-assembly air deflector 1 21 and the sub-assembly air deflector 2 22 form an air deflector assembly, which reduces the air flow in the upper part of the first air deflector 1. In particular, the two end edges of the first air deflector 1 and the side of the partition 123 away from the air passage 122 also have a wire slot, and the sub-assembly air deflector 1 21 and the sub-assembly air deflector 2 22 also have a wire slot corresponding to the wire slot position of the first air deflector 1. The wire slot is used to assist the cable routing above the overall air deflector assembly, and the wire slot is used to accommodate the cable above, reducing the space occupied by the cable.

[0088] In some embodiments, the locking column 25 includes a support column 251 and at least one pawl 252 connected to the support column 251.

[0089] Specifically, referring to Figure 8 , the first locking hole 132 and the second locking hole 213 have the same structure, and the first locking hole 132 and the second locking hole 213 include a thickened portion 1321, which can effectively increase the upper limit of the stress when the locking hole is assembled with the locking column 25. Referring to Figure 9 , the locking column 25 includes a support column 251 and at least one pawl 252 connected to the support column 251. For example, the front end of the pawl 252 has a guide structure, the diameter of the end of the pawl 252 is 7.50mm, which is smaller than the diameter of the locking hole 8.00mm, so that the pawl 252 can smoothly pass through the first locking hole 132 or the second locking hole 213. In particular, when the pawl 252 is inserted, the pawl 252 and the locking hole have a gap of 0.2mm, and when assembled in place, the pawl 252 will rebound, and the pawl 252 will make a knocking sound when it rebounds, which can remind the operator to assemble in place. The guide angle of the front end of the pawl 252 can generate two components of force on the pawl 252 when the pawl 252 advances in the locking hole. One component causes the pawl 252 to bend inward, which is beneficial to the structure of the pawl 252; the other component is the resistance to the pawl 252, and since the angle of the pawl 252 is 68.2 degrees, which is greater than 45 degrees, the resistance to the forward movement of the pawl 252 is smaller, and the force assisting the inward bending of the pawl 252 is larger. The number of pawls 252 can be three, or it can be configured as needed according to different strength requirements. Referring to Figure 11 , Figure 11The locking column 25 is matched with the locking hole. The cross-sectional view shows that a is the gap distance between the outer wall of the supporting column 251 and the inner wall of the locking hole, b is the gap distance between the bottom surface of the locking column 25 and the bottom surface of the locking hole, c is the gap distance between the bottom surface of the pawl 252 and the top surface of the locking hole, d is the height of the supporting column 251, e is the interference amount of the bottom surface of the pawl 252 and the projection surface of the locking hole, r is the radius of the supporting column 251, and R is the radius of the locking hole. Generally, a is 0.10 mm to 0.20 mm, r+a=R, b is 0 to 0.15 mm, c is 0.05 mm to 0.2 mm, d is greater than or equal to 3 mm, e is 0.5 mm to 0.8 mm, the diameter of the locking hole is the diameter of the locking column plus 2a, the height from the pawl surface to the bottom surface of the locking column is the height of the locking hole plus c, and the outer diameter of the pawl is the diameter of the locking hole plus 2e. When the first wind deflector 1, the sub-assembled wind deflector one 21 and the sub-assembled wind deflector two 22 are connected, the supporting block is inserted into the corresponding component of the ventilation assembly, the misalignment between the first wind deflector 1, the sub-assembled wind deflector one 21 and the sub-assembled wind deflector two 22 on the butt joint surface can be avoided, and the deformation of each component after being heated can also be effectively avoided. The locking column 25 is matched with the locking hole, so that the first wind deflector 1, the sub-assembled wind deflector one 21 and the sub-assembled wind deflector two 22 are connected and tightly installed, and the installation is stable.

[0090] In the embodiment, different lengths of the wind deflector assembly can be adapted to different heat dissipation scenes. The first wind deflector 1 with a fixed length and the plurality of second wind deflectors 2 extension pieces are combined to form the wind deflector assembly with different lengths, which is adapted to different heat dissipation scenes. The extension piece second wind deflector 2 is added behind the short first wind deflector 1, so that the combination replaces the original long wind deflector, thereby avoiding different wind deflector production molds, reducing the production mold cost, improving the wind deflector accessory reuse rate, and reducing the manufacturing cost of the wind deflector.
