AI Technical Summary
The existing air guide device has foam at the connection to fill the gap, but the rebound effect of the foam causes the air guide parts to be relatively far away, affecting the sealing effect. The foam is prone to disengage or wear during multiple disassembly and assembly, further affecting the sealing effect.
A wind guide device is designed, including a closure plate having a first state and a second state. In the first state, the closure plate is located at the connection of the air guide member to close the gap. In the second state, the closure plate is away from the second air guide member to facilitate the disassembly and assembly of the air guide member. The closure plate switches between two positions by driving components such as magnetic suction components or elastic components.
Through the design of the closure plate, the clearance at the connection of the air guide parts is ensured, and the problem of relatively distance between the air guide parts caused by foam rebound is avoided. During the multiple disassembly and assembly, the wear chance of the closure plate is reduced, and the good closure effect is maintained.

[0027] The utility model discloses an air guide device, which ensures the sealing effect of the gap. The utility model also provides an electronic device.
[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] like Figure 1 As shown, the embodiment of the utility model provides a wind guide device, including a first wind guide component 100 and a second wind guide component 200 corresponding to the first wind guide component 100. The airflow can flow between the first wind guide component 100 and the second wind guide component 200. Specifically, the first wind guide component 100 can guide the airflow flowing to the second wind guide component 200; the first wind guide component 100 can also guide the airflow flowing out of the second wind guide component 200.
[0030] The first air guide component 100 includes a main body 120 and a closing plate 110 movably connected to the main body 120, and the closing plate 110 has a first state and a second state;
[0031] Among them, when the closing plate 110 is in the first state, the closing plate 110 moves to the first position relative to the main body 120, and the closing plate 110 is located at the connection between the first air guide component 100 and the second air guide component 200; when the closing plate 110 is in the second state, the closing plate 110 moves to the second position relative to the main body 120, and the closing plate 110 is away from the second air guide component 200.
[0032] The air guiding device provided by the embodiment of the utility model, when the closing plate 110 is in the first state, the closing plate 110 moves to the first position relative to the main body 120, so that the closing plate 110 is located at the connection between the first air guiding component 100 and the second air guiding component 200, thereby shielding the connection between the first air guiding component 100 and the second air guiding component 200, avoiding the setting of foam filling gap, thereby ensuring the stability of the corresponding positions of the first air guiding component 100 and the second air guiding component 200, and ensuring the sealing effect of the gap generated at the connection between the first air guiding component 100 and the second air guiding component 200. Furthermore, when the closing plate 110 is in the second state, the closing plate 110 moves from the first position relative to the main body 120 to the second position relative to the main body 120, and the closing plate 110 is away from the second air guide component 200, so that the first air guide component 100 and the second air guide component 200 are relatively separated due to the gap generated at the connection, so as to reduce the chance of wear during the disassembly and assembly of the first air guide component 100 and the second air guide component 200, and ensure the sealing effect of the gap generated at the connection between the first air guide component 100 and the second air guide component 200 when the closing plate 110 is switched to the first state again.
[0033] Since the airflow can flow between the first air guide component 100 and the second air guide component 200, the gap generated at the connection between the first air guide component 100 and the second air guide component 200, when the closing plate 110 is in the first state, the closing plate 110 is located at the connection between the first air guide component 100 and the second air guide component 200, which can limit the gas from overflowing from the gap and affecting the airflow effect. For example, in the state where gas overflows at the gap, the total amount of airflow will be reduced after the ground airflow flows through the connection between the first air guide component 100 and the second air guide component 200, thereby affecting the subsequent heat dissipation effect of the airflow. Or, in the state where gas overflows at the gap, the gas overflowing from the ground will form a backflow, thereby affecting the overall heat dissipation effect. Therefore, the air guide device provided by the embodiment of the utility model can ensure the sealing effect of the gap generated at the connection between the first air guide component 100 and the second air guide component 200, thereby ensuring the heat dissipation effect.
[0034] It is understandable that both the first air guide component 100 and the second air guide component 200 have air flow channels, and gas can flow between the air flow channels of the first air guide component 100 and the air flow channels of the second air guide component 200. Specifically, the first air guide component 100 can be a PSU (Power Supply Unit) air guide cover in the server, that is, a dedicated air guide cover arranged at the rear end of the PSU, and the second air guide component 200 can be a power cage (also called a power supply compartment) of the PSU.
[0035] In a specific embodiment, when the closing plate 110 is in the first state, the closing plate 110 contacts the surface of the second air guide component 200, and is used to close the connection between the first air guide component 100 and the second air guide component 200. That is, the closing plate 110 can achieve surface contact between the closing plate 110 and the second air guide component 200 by moving or rotating, so as to close the gap between the first air guide component 100 and the second air guide component 200 by surface contact.
[0036] In this embodiment, the closing plate 110 is preferably rotatably connected to the main body 120. That is, one end of the closing plate 110 is hinged to the main body 120, and the closing plate 110 is switched between the first state and the second state by rotating the closing plate 110 relative to the main body 120. In the first state, at least the other end of the closing plate 110 contacts the surface of the second air guide member 200.
[0037] The closing plate 110 can also be made to slide with the main body 120, and the closing plate 110 can slide in the direction close to and away from the second air guide component 200 by sliding the closing plate 110 relative to the main body 120. Among them, one end of the closing plate 110 faces away from the second air guide component 200, and the other end of the closing plate 110 faces the second air guide component 200. In the process of the closing plate 110 switching from the second state to the first state, the other end of the closing plate 110 moves toward the second air guide component 200; when the closing plate 110 is in the first state, one end of the closing plate 110 is connected to the main body 120, and the other end of the closing plate 110 contacts the surface of the second air guide component 200. That is, when projected in a direction perpendicular to the first air guide component 100 and the second air guide component 200, a part of the orthogonal projection area of the closing plate 110 overlaps with the orthogonal projection area of the main body 120, and another part of the orthogonal projection area of the closing plate 110 overlaps with the orthogonal projection area of the second air guide component 200.
[0038] Of course, the closing plate 110 can also be made to contact the end of the second air guide component 200 toward the first air guide component 100, so as to form the effect of the closing plate 110 and the second air guide component 200 docking. In this embodiment, the closing plate 110 can be slidably matched with the main body 120, and the closing plate 110 can slide relative to the main body 120 in the direction close to and away from the second air guide component 200, so as to realize the switching of the closing plate 110 between the first state and the second state. That is, when projected in a direction perpendicular to the first air guide component 100 and the second air guide component 200, a part of the orthographic projection area of the closing plate 110 overlaps with the orthographic projection area of the main body 120 or the orthographic projection area of the closing plate 110 contacts but does not overlap with the orthographic projection area of the main body 120, and the orthographic projection area of the closing plate 110 contacts but does not overlap with the orthographic projection area of the second air guide component 200.
[0039] In this embodiment, the surface of the second air guide component 200 may include its inner surface and outer surface. It is understandable that the inner surface of the second air guide component 200 can enclose the air guide channel in the second air guide component 200 or the inner surface of the second air guide component 200 belongs to the channel wall of the air guide channel in the second air guide component 200. The outer surface of the second air guide component 200 is the surface of the second air guide component 200 facing outward when the second air guide component 200 is correctly installed.
[0040] In the embodiment of the utility model, the second air guide component 200 has a first surface and a second surface opposite to each other, and the first surface is located on the outer surface of the second air guide component 200; when the closing plate 110 is in the first state, the closing plate 110 contacts the first surface or the second surface. That is, the closing plate 110 can achieve the effect of sealing the connection between the first air guide component 100 and the second air guide component 200 by contacting the first surface, and can also achieve the effect of sealing the connection between the first air guide component 100 and the second air guide component 200 by contacting the second surface.
[0041] When the closing plate 110 is in the first state, in an embodiment where the closing plate 110 is used to contact the first surface to close the connection between the first air guide component 100 and the second air guide component 200, the closing plate 110 can be located outside the second air guide component 200. By moving the closing plate 110 relative to the main body 120, the closing plate 110 is adjusted in position outside the second air guide component 200, thereby enabling the closing plate 110 to switch to the first position relative to the main body 120, thereby achieving contact with the first surface of the second air guide component 200.
[0042] When the closing plate 110 is in the first state, in the embodiment where the closing plate 110 is used to contact the second surface to close the connection between the first air guide component 100 and the second air guide component 200, the closing plate 110 may be located inside the second air guide component 200, that is, the closing plate 110 is located in the air guide channel of the second air guide component 200. By the movement of the closing plate 110 relative to the main body 120, the closing plate 110 is adjusted in the air guide channel of the second air guide component 200, so that the closing plate 110 is switched to the first position relative to the main body 120, so as to contact the second surface of the second air guide component 200.
[0043] In order to facilitate the closing plate 110 to move to the first position relative to the main body 120, the air guide device further includes a first driving component, which can drive the closing plate 110 to move to the first position relative to the main body 120. The first driving component can provide a driving force directly applied to the closing plate 110, so that the closing plate 110 can move relative to the main body 120 under the action of the driving force, and the closing plate 110 moves to the first position. In addition, when the closing plate 110 moves to the first position, the driving force provided by the first driving component can be continuously provided, so that the closing plate 110 is maintained in the first position, ensuring the sealing effect on the gap.
[0044] Of course, the driving force provided by the first driving component may disappear when the closing plate 110 moves to the first position, and the closing plate 110 may maintain the first position through its own gravity, friction or an additional driving force. No specific restrictions are made here and all are within the protection scope.
[0045] The driving force provided by the first driving component can be a contact driving force or a non-contact driving force. The contact driving force can use a cylinder or a motor as the first driving component, and the driving end of the first driving component contacts the closing plate 110, and the closing plate 110 is driven to move through the driving end. The non-contact driving force is that the first driving component does not contact the physical structure of the closing plate 110, and the movement of the closing plate 110 relative to the main body 120 is driven by magnetic force or air flow pressure.
[0046] Specifically, in the first embodiment, the first driving component includes a magnetic component 300 arranged on the second air guide component 200, and the closing plate 110 can generate a magnetic force with the magnetic component 300. Under the action of the magnetic force, the closing plate 110 can move to a first position relative to the main body 120 so that the closing plate 110 is located at the connection point.
[0047] In the first embodiment described above, the driving force provided by the first driving component is a non-contact driving force, that is, the magnetic attraction force generated by the closing plate 110 and the magnetic attraction component 300. The magnetic attraction component 300 can be set as a magnet, and the closing plate 110 is a metal plate that can generate magnetic attraction with the magnet; the closing plate 110 can also be made of a magnetic material, and the magnetic attraction component 300 is a metal part that can generate magnetic attraction with the magnet; or, the closing plate 110 is made of a magnet, and the magnetic attraction component 300 is also a magnet, and the relative positions of the closing plate 110 and the magnetic attraction component 300 are respectively positive and negative, so that the closing plate 110 and the magnetic attraction component 300 can also generate magnetic attraction.
[0048] Moreover, in an embodiment where the magnetic attraction component 300 is a metal part that can generate magnetic attraction force with a magnet, the second air guide component 200 can be set as a metal part, and the magnetic attraction component 300 is a partial structure on the second air guide component 200, that is, the second air guide component 200 and the magnetic attraction component 300 can be an integrated structure or a split structure.
[0049] In order to improve the sealing effect and the stability of the surface contact between the closing plate 110 and the second air guide component 200, the magnetic component 300 can be arranged on the second air guide component 200 and protrude from the surface of the second air guide component 200, and the closing plate 110 has a recessed structure that cooperates with the magnetic component 300; when the closing plate 110 is in the first state, the magnetic component 300 can be partially or completely embedded in the recessed structure, and the surface of the second air guide component 200 is in contact with the surface of the closing plate 110.
[0050] In the second embodiment, the first driving component includes a first elastic component, one end of the first elastic component is connected to the closing plate 110, and the other end of the first elastic component is connected to the main body 120. The closing plate 110 can move to a first position relative to the main body 120 under the elastic restoring force of the first elastic component, so that the closing plate 110 is located at the connection point.
[0051] In the above-mentioned second embodiment, the driving force provided by the first driving component is a contact driving force, that is, one end of the first elastic component is connected to the closing plate 110, and the other end of the first elastic component is connected to the main body 120. The elastic restoring force of the first elastic component is applied to the closing plate 110 through one end of the first elastic component connected to the closing plate 110, thereby forming a driving force that drives the closing plate 110 to move to the first position relative to the main body 120.
[0052] Specifically, the first elastic component may be a torsion spring, and the two ends of the first elastic component are torsion arms of the torsion spring. The first elastic component may also be a tension spring or a compression spring, etc. The first elastic component may also be an elastic block or an elastic rope made of an elastic material, etc.
[0053] In order to facilitate moving the closing plate 110 to the second position so that the closing plate 110 is in the second state, the air guiding device also includes a second driving component, which can drive the closing plate 110 to move to the second position relative to the main body 120.
[0054] In a specific embodiment, the second driving component includes a second elastic component 400, one end of the second elastic component 400 is connected to the closing plate 110, and the other end of the second elastic component 400 is connected to the main body 120; the closing plate 110 can move relative to the main body 120 under the elastic restoring force of the second elastic component 400, so that the closing plate 110 switches from the first state to the second state.
[0055] Specifically, the second elastic component 400 may be a torsion spring, and the two ends of the second elastic component 400 are torsion arms of the torsion spring. The second elastic component 400 may also be a tension spring or a compression spring, etc. The second elastic component 400 may also be an elastic block or an elastic rope made of an elastic material, etc.
[0056] The first driving component and the second driving component can be operated at intervals, that is, only one driving component applies a corresponding driving force to the closing plate 110. The first driving component and the second driving component can also drive the closing plate 110 together, which requires an external operator or an external instrument to assist in driving the closing plate 110.
[0057] Taking the implementation in which the first elastic component includes the magnetic component 300 and the second driving component includes the second elastic component 400 as an example, the different distances between the closing plate 110 and the magnetic component 300 can make the magnetic attraction forces generated by the closing plate 110 and the magnetic component 300 different, and the maximum value of the magnetic attraction forces generated by the closing plate 110 and the magnetic component 300 can overcome the elastic restoring force of the second elastic component 400. Therefore, when the closing plate 110 is in the first state, the distance between the closing plate 110 and the magnetic component 300 is small enough to make the magnetic attraction forces generated by the closing plate 110 and the magnetic component 300 be the maximum value, ensuring that the magnetic attraction forces generated by the closing plate 110 and the magnetic component 300 can overcome the elastic restoring force of the second elastic component 400, thereby ensuring that the closing plate 110 can maintain the first position relative to the main body 120, thereby ensuring the stability of the closing plate 110 at the connection between the first air guide component 100 and the second air guide component 200. When it is necessary to switch the closing plate 110 from the first state to the second state, the closing plate 110 can be moved manually by an operator or by an external device applying force, so that the closing plate 110 moves a distance to the second position relative to the main body 120. During this process, the sum of the force provided by the operator manually or by an external device and the elastic restoring force of the second elastic component 400 is greater than the maximum value of the magnetic attraction force generated by the closing plate 110 and the magnetic component 300. At least the closing plate 110 needs to be moved to a predetermined distance away from the magnetic component 300, so that the magnetic attraction force generated by the closing plate 110 and the magnetic component 300 at the predetermined distance is less than the elastic restoring force of the second elastic component 400, so that the closing plate 110 is driven by the elastic restoring force of the second elastic component 400 to move to the second position relative to the main body 120.
[0058] In order to further improve the sealing effect of the gap, the closing plate 110 has an elastic layer. When the closing plate 110 is in the first state, the elastic layer is located between the closing plate 110 and the second air guide component 200 and is in an elastic deformation state. The elastic layer can be made of elastic materials such as rubber. Through the elastic deformation of the elastic layer, the gap between the closing plate 110 and the second air guide component 200 can be effectively avoided, thereby further improving the sealing effect of the gap generated by the connection between the first air guide component 100 and the second air guide component 200.
[0059] In order to improve the position control of the closing plate 110 , the main body 120 has a limiting structure 121 capable of limiting the movement of the closing plate 110 . The limiting structure 121 can limit the closing plate 110 to the second position when the closing plate 110 is in the second state.
[0060] In a specific embodiment, one end of the closing plate 110 is hinged to the main body 120 via a rotating shaft 122, and a torsion spring as the second elastic member 400 is sleeved on the rotating shaft 122. The limiting structure 121 is a covering structure on the main body 120 that covers one end of the closing plate 110, one side of the closing plate 110 contacts a torsion arm of the torsion spring, and the other side of the closing plate 110 contacts the edge of the covering structure, which can limit the closing plate 110 from continuing to move when it is in the second state, so that the closing plate 110 is limited to the second position.
[0061] The rotating shaft 122 may be made of existing components such as a PIN Header, or the rotating shaft 122 may be processed separately.
[0062] The embodiment of the utility model further provides an electronic device, comprising a heat-generating component and any of the above-mentioned air-guiding devices; wherein, when the closing plate 110 of the air-guiding device is in a first state, the airflow guided by the air-guiding device can flow through the heat-generating component.
[0063] Since the above-mentioned air guide device has the above-mentioned technical effects, the electronic device having the above-mentioned air guide device should also have the same technical effects, which will not be described one by one here.
[0064] The electronic device may be specifically a server, or may be other equipment having at least two air guide components.
[0065] In this embodiment, the heat-generating component may be located in the air flow channel of one of the first air guide component 100 and the second air guide component 200 , or may be located outside the first air guide component 100 and the second air guide component 200 .
[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
