Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention, and fig. 2 is an exploded structure diagram of fig. 1.

In a specific embodiment of the present invention, the variable duct wind scooper mainly includes a hood 2, a rotating shaft 3, a wind shield 4 and a locking mechanism 5.

The cover body 2 is a main body structure of the wind scooper, generally has a U-shaped structure, and is specifically covered in the case 1 to cover the heat generating components in the case 1. Generally, the top wall of the cover 2 is a plane and is parallel to the bottom plate of the chassis 1, and the two side walls of the cover 2 are vertical bending edges and respectively cling to the two side inner walls of the chassis 1.

The rotation shaft 3 is vertically connected to the bottom surface of the top wall of the cover 2, and the rotation shaft 3 hangs down from the top wall of the cover 2 and extends toward the bottom plate of the cabinet 1.

The wind deflector 4 is connected on the rotating shaft 3 and can rotate around the rotating shaft 3 to realize horizontal turning motion on the bottom surface of the top wall of the cover body 2 and the surface of the bottom plate of the case 1, and further realize circumferential angle position adjustment of the wind deflector 4 in the case 1.

Meanwhile, the wind shield 4 is always kept in a vertical state on the rotating shaft 3, because the radiating airflow of the case 1 generally flows along the length (depth) direction of the case 1, and the wind shield 4 is kept vertical, namely, the wind shield can be used for shielding wind, intercepting wind, guiding wind and the like by utilizing the side surfaces of two sides of the wind shield.

The locking mechanism 5 is mainly used for fixing the wind deflector 4 at the current angular position, so that after the wind deflector 4 performs horizontal overturning motion, the wind deflector 4 is kept at the target angular position for a long time, the guiding state of a preset angle is maintained, and the angular position is prevented from being changed due to blowing of heat dissipation airflow.

Therefore, the variable air duct air guide cover provided by the embodiment can realize real-time adjustment of the air duct of the heat dissipation air flow in the case 1 through the horizontal turning motion of the wind shield 4 on the rotating shaft 3, so that the heat dissipation air flow generates flow direction change in the corresponding direction when passing through the wind shield 4 in the flowing process, and further can guide the heat dissipation air flow to the region where the target heat generating component is located. Compared with the prior art, for servers with different configurations, the circumferential angle position of the wind shield 4 can be correspondingly adjusted according to the actual distribution condition of the target heating component in the case 1, and the universality for the servers with different configurations can be conveniently and quickly realized.

In an alternative embodiment of the rotating shaft 3, in order to improve the installation stability of the rotating shaft 3 in the cover 2, in this embodiment, the top end of the rotating shaft 3 is vertically connected to the bottom surface of the top wall of the cover 2 and extends all the way toward the bottom plate of the case 1 in the vertical direction, and the bottom end of the rotating shaft 3 is connected to the surface of the bottom plate of the case 1, that is, the top end of the rotating shaft 3 is connected to the top wall of the cover 2, and the bottom end of the rotating shaft 3 is connected to the bottom plate of the case 1, and the rotating shaft 3 is clamped and fixed between the cover 2 and the case 1.

Similarly, in this embodiment, one side of the wind deflector 4 is rotatably connected to the rotating shaft 3, and the top end of the wind deflector 4 can be extended to the top wall bottom surface of the cover 2 for abutting connection, and the bottom end of the wind deflector 4 can be extended to the bottom plate surface of the chassis 1. Of course, since the wind deflector 4 needs to ensure the rotational degree of freedom, the top end of the wind deflector 4 does not abut against the top wall of the cover 2 tightly, and the bottom end of the wind deflector 4 does not abut against the bottom plate surface of the chassis 1 tightly, but the height of the wind deflector 4 can be as large as possible to increase the wind shielding area. In addition, since other parts may be mounted on the bottom surface of the chassis 1, the height of the bottom end of the wind deflector 4 may be adjusted according to actual conditions to avoid motion interference.

Fig. 7 is a schematic view showing various horizontal turning states of the wind deflector 4, as shown in fig. 7.

Further, in order to ensure that the wind deflector 4 can realize 360-degree horizontal turnover movement and avoid the wind deflector 4 from generating movement interference with the inner wall of the case 1 in the process of horizontal turnover, in the embodiment, the rotating shaft 3 is specifically arranged at the center of the width direction of the cover body 2 and is generally arranged at the center of the length direction of the cover body 2. So set up, the distance of rotation axis 3 to 1 both sides inner wall of quick-witted case equals, as long as ensure that the length of deep bead 4 equals or is less than half of the width of cover body 2, can guarantee that deep bead 4 can carry out 360 horizontal turning motion, maximize wind channel control range round rotation axis 3.

Correspondingly, in this embodiment, the length of the wind deflector 4 is specifically half of the width of the cover 2, that is, 2 wind deflectors 4 can be simultaneously arranged in the cover 2 side by side, and because the width of the cover 2 is approximately equal to the width of the chassis 1, only 2 wind deflectors 4 need to be distributed side by side, and the heat radiation airflow of the chassis 1 can be completely cut off. Meanwhile, the longitudinal inner side of the wind deflector 4 is pivotally connected to the rotary shaft 3, and the longitudinal outer side of the wind deflector 4 is almost abutted against the inner wall of the cover 2 in parallel with the width direction.

In addition, the specific number of the wind deflectors 4 is not fixed, and generally at least two wind deflectors are provided. As described above, when two wind deflectors 4 are provided, the heat radiation airflow can be completely cut off. Of course, only 1 wind deflector 4 may be provided, and at this time, the wind deflector 4 can only achieve the function of blocking half of the heat dissipation airflow, for example, the heat generating component is provided on the left side of the chassis 1, and the wind deflector 4 only needs to be horizontally turned to the right side, and vice versa. In the same way, 3 or more wind deflectors 4 can be arranged, and the stopping, blocking and guiding functions of the wind deflectors 4 on the heat dissipation airflow are more complex. However, no matter how many wind deflectors 4 are arranged on the rotating shaft 3, the horizontal turning motion of each wind deflector 4 is independent and does not influence each other, that is, each wind deflector 4 can independently perform the turning motion without influencing the turning motion of the other wind deflectors 4.

As shown in fig. 3, fig. 3 is a schematic view showing a specific structure of the windshield 4.

In an alternative embodiment of the wind deflector 4, the wind deflector 4 is embodied in a split structure, and mainly includes a front panel 41, a rear panel 42, a positioning hole 43 and a positioning column 44. The front panel 41 and the rear panel 42 are two side surface structures of the wind screen 4, and they are fastened and connected together. Specifically, the front panel 41 and the rear panel 42 are adhered to each other by an adhesive, and may be connected by a fastener such as a screw. The positioning hole 43 is opened on the inner surface of the front panel 41, the positioning column 44 is convexly arranged on the inner surface of the rear panel 42, and the positioning column 44 can form shaft hole clamping fit with the positioning hole 43. With such an arrangement, the front panel 41 and the rear panel 42 can be quickly positioned and connected by the matching between the positioning hole 43 and the positioning column 44.

In addition, in order to ensure that the user can accurately adjust the circumferential angular position of each wind deflector 4 in the cover 2, the present embodiment adds an index plate 6 on the surface of the cover 2. Specifically, the index plate 6 is covered on the top surface of the cover 2, and has a generally disk shape, and is provided with a scale on its circumferential edge for indicating an angle. So set up, when the user needs the circumferential angle position of accurate adjustment deep bead 4, only need contrast the angle scale on the graduated disk 6, with deep bead 4 adjustment to the target position can. Of course, since the wind shielding plate 4 is disposed in the cover 2, it is not easy to observe, in this embodiment, the index plate 6 is made of a transparent material, and the cover 2 may also be made of a transparent material.

As shown in fig. 4, fig. 4 is a schematic structural diagram of the locking mechanism 5.

In an alternative embodiment of the locking mechanism 5, the locking mechanism 5 mainly comprises a pin member 51 and a locking hole 52. The plug pin assemblies 51 can be vertically and telescopically inserted into the wind shield 4, and the clamping holes 52 are formed in the bottom surface of the dividing plate 6 and are uniformly distributed along the circumferential direction of the dividing plate 6. This joint hole 52 can form the joint cooperation with bolt subassembly 51 to stretch out to the top of deep bead 4 back along vertical direction at bolt subassembly 51, insert and establish into the joint and connect in the hole 52 and form the connection. So set up, after the adjustment of the circumference angular position of deep bead 4, can upwards slide bolt subassembly 51 on the deep bead 4, utilize the joint hole 52 of graduated disk 6 bottom surface to fix bolt subassembly 51 to fix deep bead 4 at current angular position.

Further, in an alternative embodiment with respect to the latch assembly 51, the latch assembly 51 mainly includes a sliding rod 511, an elastic member 512 and a pressing cap 513, and a through hole 45 and a ring 46 are provided on the wind deflector 4.

As shown in fig. 5 and 6, fig. 5 is a detailed structural schematic diagram of the plug pin assembly 51, and fig. 6 is an exploded structural schematic diagram of fig. 5.

The through hole 45 is formed in the outer side edge of the wind deflector 4 in the length direction, extends in the vertical direction, and has through upper and lower ends, and the through hole is mainly used for being matched with the sliding rod 511, so that the sliding rod 511 can slide up and down in the through hole 45. The ring 46 is formed on an inner wall of the through hole 45, and has an inner diameter larger than that of the through hole 45, and is mainly used for mounting the elastic member 512, such as a spring, so that the bottom end of the elastic member 512 abuts against or is connected to the top surface of the ring 46.

The sliding rod 511 is a main structure of the plug pin assembly 51, and the elastic element 512 is not only mounted on the annular platform 46, but also sleeved on the sliding rod 511, for example, a spring is sleeved on the periphery of the sliding rod 511. The pressing cap 513 is arranged at the top end of the sliding rod 511, and is mainly used for a user to perform pressing operation, meanwhile, the bottom end face of the pressing cap 513 is kept in butt joint with the top end of the elastic piece 512, and the top end of the pressing cap 513 is mainly used for forming clamping fit with the clamping hole 52 in the bottom face of the index plate 6.

With the arrangement, when the wind shield 4 needs to be unlocked to adjust the circumferential position, a user only needs to press the top end face of the pressing cap 513 in the clamping hole 52 or pull the bottom end of the sliding rod 511 from the bottom, so that the sliding rod 511 descends in the through hole 45 until the pressing cap 513 is separated from the clamping hole 52, the wind shield 4 can be unlocked, at the moment, the wind shield 4 can be freely turned horizontally, and therefore circumferential angle position adjustment is achieved, in the process, the elastic part 512 is continuously compressed, and the pressing cap 513 is pressed to be separated from the clamping hole 52 and then is abutted to the bottom face of the index plate 6 under the elastic action of the elastic part 512; when need lock deep bead 4 in order to keep it at current circumferential position, the user only need with deep bead 4 level upset to target angular position for originally the butt press cap 513 in the graduated disk 6 bottom surface aim at the joint hole 52 of target angular position department can, later under the elastic force effect of elastic component 512, press cap 513 will be automatic upward and stretch out to in the joint hole 52, form the joint and lock.

Furthermore, in order to avoid the pressing cap 513 from suddenly rushing out of the clamping hole 52 under the action of the elastic force to cause the plug pin assembly 51 to be separated from the wind deflector 4, a limiting plate 514 is additionally arranged at the bottom end of the sliding rod 511 in the embodiment to abut against the bottom surface of the wind deflector 4 through the limiting plate 514, so that the maximum ascending stroke of the sliding rod 511 in the through hole 45 is limited.

The embodiment also provides a server, which mainly includes a chassis 1 and a variable air duct wind scooper disposed in the chassis 1, wherein the specific content of the variable air duct wind scooper is the same as the related content, and is not described herein again.

The variable air duct wind scooper provided by the embodiment can be applied to various scenes in a server.

As shown in fig. 8, fig. 8 is a first application scenario of the wind scooper. If two heating components (such as CPUs) are arranged in parallel in the server, the two wind shields 4 can be respectively turned to an angle parallel to the length direction of the case 1, so that the internal space of the wind shield is divided into two parts, the heat dissipation airflow is divided into two parts, and the two heating components are respectively cooled.

As shown in fig. 9, fig. 9 is a second application scenario of the wind scooper. When the server is not fully assembled and only one side is provided with a heating component, one of the wind shields 4 can be turned to the other side of the case 1 and is vertically opposite to the radiating airflow, so that part of the radiating airflow on the side is stopped, and the other wind shield 4 can be turned to be parallel to the length of the case 1, and the part of the radiating airflow on the side can be ensured to smoothly pass through.

As shown in fig. 10, fig. 10 is a third application scenario of the wind scooper. For the remaining more complex configurations, two wind deflectors 4 or a greater number of wind deflectors 4 may be selected, depending on the actual situation, in their respective circumferential angular positions, so that an arbitrary angle (non-zero degree) is formed between the two wind deflectors 4.
