[0044] The core of the utility model is to disclose an air guide structure 100 to improve assembly efficiency while avoiding interference between the air guide structure and the heating device.

[0045] Another core of the utility model is to disclose a fan heat dissipation assembly including the above-mentioned air guide structure.

[0046] The following is an explanation of the embodiments with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions of the utility model described in the claims. It should be noted that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings. In the absence of conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0047] Combination Figure 1-Figure 7The air guide structure 100 disclosed in the embodiment of the utility model is used to be arranged at the air outlet of the fan device 200, and includes a fixed air guide member 110 and a movable air guide member 120. The fixed air guide member 110 is used to be arranged on the fan device 200, and the movable air guide member 120 is rotatably arranged on the fixed air guide member 110 through a rotating shaft member 130. The movable air guide member 120 and the fixed air guide member 110 form an air guide channel 101 connected to the air outlet of the fan device 200, and the movable air guide member 120 has a contact portion that can be pushed by an interference device 300 and rotate around the rotating shaft member 130. Among them, the interference device 300 refers to a structure that is easy to interfere with the installation of the air guide structure 100, such as a heating device or a heating component.

[0048] When the air guide structure 100 disclosed in this embodiment is used for installation, the movable air guide member 120, which is easy to contact and interfere with the interference device 300, can rotate around the rotating shaft 130 at a certain angle relative to the fixed air guide member 110 when contacting the interference device 300, thereby realizing adaptive adjustment of the air guide structure 100.

[0049] Compared with the prior art, the utility model configures the air guide structure 100 as two independent structures, namely a fixed air guide member 110 and a movable air guide member 120. The fixed air guide member 110 can remain stationary relative to the fan device 200, and the movable air guide member 120 can rotate automatically to adjust its position according to the degree of interference between the air guide member 110 and the interference device 300, thereby avoiding the situation where the air guide structure 100 cannot be installed due to interference with the interference device 300 during the installation process, and at the same time, the uncontrollability of manual adjustment is avoided through adaptive adjustment.

[0050] The fixed air guide member 110 can be connected to the fan device 200 by bolt connection, bonding, welding, etc. Preferably, the connection is made in a detachable manner.

[0051] Those skilled in the art will appreciate that by adjusting the center of gravity of the movable air guide member 120, it is possible to ensure that the movable air guide member 120 remains motionless at the initial position when it is not subjected to the thrust of the interference device 300, or by setting a relevant limiting structure, it is possible to ensure that the movable air guide member 120 remains motionless at the initial position when it is not subjected to the thrust of the interference device 300 or other forces.

[0052] To further optimize the solution, in order to avoid vibration during the transportation of the air guide structure 100, a reset member is preferably provided to maintain the relative position of the movable air guide member 120 and the fixed air guide member 110. If the interference device 300 is defined to apply a forward rotation thrust to the movable air guide member 120, the reset member is used to apply a force to keep the movable air guide member 120 in the initial position to ensure the stability of the position of the movable air guide member 120. When the movable air guide member 120 is not in contact with the interference device 300 or no interference occurs, under the action of the reset member, the movable air guide member 120 can be stably maintained in the initial position; when the movable air guide member 120 is pushed to rotate by the interference device 300, the reset member is deformed and can provide a force for the movable air guide member 120 to rotate to the initial position.

[0053] For example, the reset member may be a return spring, which is disposed at the rotating shaft 130 and connected to the rotating shaft 130. When the movable air guide 120 is rotated by the force of the interference device 300, the return spring rotates and deforms with the rotating shaft 130, so as to be able to tighten the movable air guide 120 in the direction of the initial position until the movable air guide 120 is stabilized at a certain rotation position under the thrust of the interference device 300 and the pulling force of the return spring. Alternatively, the reset member may also be implemented as a torsion spring, which is disposed at the rotating shaft 130 and has two torsion arms connected to the fixed air guide 110 and the movable air guide 120 respectively. When the movable air guide 120 is rotated by the force of the interference device 300, the two torsion arms of the torsion spring approach each other, thereby providing a force to press the movable air guide 120 toward the initial position.

[0054] The above-mentioned reset member can also be implemented as a compression spring or a tension spring, and its two ends are respectively connected to the fixed air guide member 110 and the movable air guide member 120. When the movable air guide member 120 rotates due to the force of the interference device 300, the compression spring is compressed or the tension spring is stretched, thereby providing a force to reset the movable air guide member 120, which will not be repeated here.

[0055] Combination Figure 4-Figure 5 In one embodiment, the movable air guide member 120 includes a main air guide plate and a guide plate 123. The main air guide plate is rotatably disposed on the fixed air guide member 110 through a rotating shaft member 130. The guide plate 123 is connected to the main air guide plate and has an angle with the extension direction of the main air guide plate. It is inclined toward the direction of the fixed air guide member 110 and is used as the above-mentioned contact portion to abut against the interference device 300.

[0056] Those skilled in the art can understand that the interference device 300 is usually a regular box-shaped structure as a whole, and the fan device 200 is used to provide a heat exchange airflow that can blow against the side walls of the interference device 300 to drive the airflow to exchange heat. Therefore, the air outlet direction of the air guide channel 101 of the air guide structure 100 usually needs to be parallel to the side walls of the interference device 300, that is, the air guide channel 101 of the air guide structure 100 usually needs to outlet air horizontally, and because the fan device 200 is used to generate a cold airflow for heat exchange, for the sake of heat dissipation efficiency, the fan device 200 should be set at a higher position to avoid the cold airflow from sinking directly to the bottom. Therefore, the interference device 300 is easy to interfere with the air guide structure 100 in that the part of the air guide channel 101 outlet of the air guide structure 100 overlaps with the interference device 300, resulting in part of the airflow being unable to flow horizontally directly. Therefore, combined with Figure 4 and Figure 5 The setting of the guide plate 123 can ensure that the air guide structure 100 and the interference device 300 are in contact and realize automatic position adjustment, while also ensuring that the heat exchange airflow can be blown out in the horizontal direction and upward in the horizontal direction at the outlet of the air guide channel 101.

[0057] Combination Figure 7 The movable air guide 120 is usually an integrated structure and is formed by bending a metal plate. If the air outlet direction of the fan device 200 itself / the air outlet is a horizontal air outlet direction, the main air guide plate has a certain inclination angle relative to the horizontal direction, so as to guide the heat exchange airflow with a lower temperature to a higher position, so as to facilitate the circulation of the heat exchange airflow. At the same time, since the heat exchange airflow usually needs to flow in the horizontal direction, the main air guide plate includes an inclined portion 121 and a horizontal portion 122, and the inclined portion 121 and the horizontal portion 122 are connected. When the movable air guide member 120 is in the initial position, the inclined portion 121 has an angle with the air outlet direction of the fan device 200, and the horizontal portion 122 remains parallel to or has a smaller angle with the air outlet direction of the fan device 200, that is, the inclined portion 121 has an angle with the horizontal direction, and the horizontal portion 122 remains parallel to or has a smaller angle with the horizontal direction. The heat exchange airflow blown out by the fan device 200 can first flow upward under the guidance of the inclined portion 121, and then be blown out in the horizontal direction under the guidance of the horizontal portion 122.

[0058] The inclined portion 121 and the horizontal portion 122 are both plate-shaped structures.

[0059] The fixed air guide member 110 includes an air guide side plate 112 and an air guide top plate 111. The air guide side plates 112 are used to connect with the fan equipment 200, and there are two of them, which are arranged on both sides of the movable air guide member 120. The two sides of the movable air guide member 120 are rotatably connected to the air guide side plates 112 through the rotating shaft member 130. The air guide top plate 111 is opposite to the movable air guide member 120, and both sides are connected to the air guide side plates 112. The air guide side plates 112, the air guide top plate 111 and the movable air guide member 120 together form the above-mentioned air guide channel 101.

[0060] The above-mentioned fixed air guide member 110 can be set as an integrated structure and formed by bending a metal plate. Figure 6 A mounting flap 113 is provided at the end of the wind guide side plate 112, and the mounting flap 113 can be connected to the fan device 200 by bolt connection or the like.

[0061] Combination Figure 6 The movable air guide member 120 is perpendicular to the two air guide side plates 112 and can rotate between the two air guide side plates 112. In order to achieve the rotation connection with the air guide side plates 112, the movable air guide member 120 is combined with the movable air guide member 120 to rotate between the two air guide side plates 112. Figure 7 Rotating matching plates 125 are provided on both sides of the inclined portion 121 , and a rotating shaft hole for the rotating shaft member 130 to pass through is opened on the rotating matching plates 125 . The inclined portion 121 is rotatably connected to the fixed air guide member 110 through the rotating matching plates 125 .

[0062] A further optimized solution is to set the rotating matching plate 125 and the wind guide side plate 112 to always overlap each other during the rotation of the movable wind guide 120, so as to ensure that the formed wind guide structure 100 does not leak air from both sides. In addition, by reasonably setting the shape of the rotating matching plate 125, the rotating matching plate 125 can limit the extreme position of the rotation of the movable wind guide 120.

[0063] For example, combined with Figure 4-Figure 7 When the movable air guide member 120 is pushed to rotate by the interference device 300, the rotating matching plate 125 follows the rotation until it abuts against the air guide top plate 111, and the movable air guide member 120 cannot continue to rotate.

[0064] The movable air guide 120 can also be maintained in the initial position by setting a limiter, for example, a first limiter can be set on the fixed air guide 110, and the first limiter is used to abut against the movable air guide 120 to limit the initial position of the movable air guide 120 rotation; or a second limiter 124 is set on the movable air guide 120, and the second limiter 124 is used to abut against the fixed air guide 110 to limit the initial position of the movable air guide 120 rotation. The first limiter and the second limiter can also be set at the same time.

[0065] The above-mentioned first limit member can be a limit structure (such as a flap, a stop column, a limit block) arranged on the side of the air guide side plate 112 facing away from the fan equipment 200. When the movable air guide member 120 is in the initial position, the first limit member can contact the inclined portion 121 and limit the continued movement of its position.

[0066] See also Figure 7 The above-mentioned second limiting member can be a limiting structure (such as a flap, a blocking column, a limiting block) arranged on the horizontal part 122 and extending in the direction of the air guide top plate 111. When the movable air guide member 120 is in the initial position, the second limiting member can contact the air guide top plate 111 and limit the continued movement of its position.

[0067] The fan heat dissipation assembly disclosed in the embodiment of the utility model includes the above-mentioned air guide structure 100 and the fan device 200, so it also has the above-mentioned structure and beneficial effects, which will not be repeated here.

[0068] In one embodiment, the fan heat dissipation assembly disclosed in the embodiment of the utility model is used to be arranged in a sealed box 400 and dissipate heat for the interference device 300 in the sealed box 400. Figure 1-Figure 3 The fan device 200 has an air outlet and an air return outlet, and the air outlet is arranged above the return air outlet. The air outlet is connected to the above-mentioned air guide structure 100, which can blow out cooling air with a relatively low temperature. The cooling air returns to the fan device 200 from the return air outlet after heat exchange with the interference device 300. The fan device 200 has a cooling system. The cooling air with a relatively high temperature is cooled by the cooling system at the fan device 200 and can be discharged from the air outlet again for heat exchange circulation.

[0069] The fan device 200 can be detachably mounted on the side wall of the sealed box 400 through the mounting assembly 210. The sealed box 400 can be a housing of an electronic device, and the interference device 300 is a functional component inside the housing of the electronic device. The sealed box 400 can also be a sealed container, and the interference device 300 is an electronic device running inside the container.

Various modifications to these embodiments will be obvious to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. The specific technical means in some embodiments can be combined in part or in whole into another embodiment without being explicitly excluded by another embodiment. Therefore, the utility model will not be limited to the embodiments shown in this article, but will conform to the widest range consistent with the principles and novel features disclosed herein.
