Description

Technical Field

[0001] The present application relates to the technical field of server heat dissipation, and in particular to an air guide device and a heat dissipation system. Background Art

[0002] As the computing power and functions of servers increase, the power consumption of various components in the server gradually increases. There are more and more high-power devices that need to be cooled, and their distribution is becoming more and more dispersed. Therefore, air scoops for assisting server cooling have appeared on the market. However, during the operation of the server, different configurations may have different cooling requirements. This leads to the fact that in some cases, the air scoop cannot well match the cooling requirements of the current components, which may cause some components to overheat or the air volume cannot be fully utilized. Utility Model Content

[0003] Based on this, it is necessary to provide an air guide device and a heat dissipation system, which can adjust the air outlet of the air guide device according to different heat dissipation requirements so that it can better match the current heat dissipation requirements.

[0004] A wind guide device, comprising:

[0005] The air guide cover body has a first channel and a second channel that can be connected to the air outlet of the chassis, and the second channel can be connected to the external environment;

[0006] a wind shield, movably connected to the wind guide cover body, the wind shield being configured to move relative to the wind guide cover body to switch between a first position and a second position; and

[0007] A first locking mechanism connected to the air guide cover body;

[0008] The wind shield located at the first position blocks the first channel to close the first channel, and the wind shield is locked to the first locking mechanism; the wind shield located at the second position is separated from the first channel, and the first channel can be connected to the external environment.

[0009] In the above-mentioned wind guide device, the wind shield can move relative to the wind guide cover body to switch between the first position and the second position. When the wind shield is in the first position, it can block the first channel to close the first channel, so that the airflow flowing out of the chassis outlet cannot flow out through the first channel, but all flows out through the second channel, thereby concentrating the air volume to cool the components corresponding to the second channel. And when the wind shield is in the first position, it is locked in the first locking mechanism to prevent the wind shield from moving relative to the wind guide cover body, so that it can be stably maintained in the first position. When the wind shield is in the second position, the wind shield is separated from the first channel, and the first channel can be connected to the external environment at this time. Therefore, the airflow flowing out of the chassis outlet can flow out through the first channel and the second channel, thereby cooling the components corresponding to the first channel and the second channel at the same time. Therefore, the position of the wind shield can be adjusted to switch between the first position and the second position, thereby changing the flow pattern of the airflow to meet different heat dissipation requirements. For example, when the heat dissipation requirement of the device corresponding to the second channel is high and the heat dissipation requirement of the device corresponding to the first channel is low, the wind shield can be adjusted to the first position; when the devices corresponding to the first channel and the second channel both have certain heat dissipation requirements, the wind shield can be adjusted to the second position.

[0010] In some embodiments, the wind guide cover body has a plurality of the first channels, and the wind guide device has a plurality of the wind shielding members corresponding one by one to the plurality of the first channels, each of the wind shielding members can block the corresponding first channel when located at the first position, and each of the wind shielding members can be separated from the corresponding first channel when located at the second position.

[0011] By providing a plurality of wind shields corresponding to the plurality of first channels one by one, the positions of the corresponding wind shields can be adjusted according to the heat dissipation requirements of the components corresponding to the first channels, so that the components corresponding to the first channels can all obtain better heat dissipation, are less likely to overheat, and are less likely to waste air volume. In this way, a wider range of heat dissipation requirements can be better met, making the air guide device more widely applicable.

[0012] In some embodiments, the wind shield is rotatably connected to the wind guide cover body, and the wind shield is configured to rotate relative to the wind guide cover body to switch between the first position and the second position.

[0013] The wind shield can be adjusted to the first position or the second position by rotating the wind shield relative to the wind guide cover body to meet different heat dissipation requirements. This movement of the wind shield is simple and has low operation difficulty, making it easy to adjust the position of the wind shield.

[0014] In some embodiments, one of the wind shield and the wind guide cover body is provided with a rotation hole, and the other is provided with a rotation shaft, and the rotation shaft is rotationally matched with the rotation hole.

[0015] By cooperating with the axial hole between the wind shield and the wind guide cover body, a rotational connection between the two can be achieved, so that the wind shield can rotate relative to the wind guide cover body to adjust the position of the wind shield to the first position or the second position to meet different heat dissipation requirements.

[0016] In some embodiments, the first locking mechanism includes a first plug-in portion connected to the wind guide cover body, and a second plug-in portion is provided on the wind shield. One of the first plug-in portion and the second plug-in portion is a slot and the other is an insert block. The insert block can be inserted into the slot to lock the wind shield in the first position.

[0017] By inserting the plug-in fitting structure into the slot, the wind shield reaching the first position can be locked there, making it difficult for the first channel to open due to leaving the first position, thereby allowing the first channel to remain in a closed state more stably.

[0018] In some embodiments, the first locking mechanism includes a plurality of the first plug-in portions that are spaced apart from each other, and the wind shield is provided with a plurality of the second plug-in portions that plug and cooperate with the plurality of the first plug-in portions in a one-to-one correspondence.

[0019] By means of the corresponding plug-in cooperation of the plurality of first plug-in parts and the plurality of second plug-in parts, the wind shielding member can be locked therein more stably, so that the first channel can be kept in a closed state more stably.

[0020] In some embodiments, the first locking mechanism can be snapped onto the wind shield located at the first position to lock the wind shield at the first position.

[0021] By means of the snap-fitting cooperation between the first locking mechanism and the wind shield, the wind shield that reaches the first position can be locked there, so that it is not easy for the first channel to open due to the wind shield leaving the first position, thereby allowing the first channel to remain in a closed state more stably.

[0022] In some embodiments, the wind guiding device includes a second locking mechanism, and the wind shielding member located at the second position can be locked to the second locking mechanism.

[0023] The wind shield member that reaches the second position is locked there by the second locking mechanism, so that it is not easy to block the first channel after leaving the second position and cause the first channel to close, thereby allowing the first channel to remain in an open state more stably.

[0024] In some embodiments, the second locking mechanism includes a resisting member connected to the wind deflector body, and the resisting member can resist the wind shield to lock the wind shield in the second position.

[0025] By the abutting member abutting against the wind shield member, the wind shield member reaching the second position can be locked there, making it difficult for it to leave the second position and block the first channel to cause the first channel to close, thereby allowing the first channel to remain open more stably.

[0026] A heat dissipation system comprises the above-mentioned air guiding device.

[0027] The above-mentioned heat dissipation system, by applying the above-mentioned air guide device, can adjust the air outlet of the air guide device according to different heat dissipation requirements of the server, so as to better match the current heat dissipation requirements.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0042] See also Figures 1 to 3 , an air guiding device provided in one embodiment of the present application includes an air guiding cover body 100, an air shield 200 and a first locking mechanism 300. The air guiding cover body 100 has a first channel 110 and a second channel 120 which can be connected to the air outlet of the chassis, and the second channel 120 can be connected to the external environment. The air shield 200 is movably connected to the air guiding cover body 100, and the air shield 200 is configured to move relative to the air guiding cover body 100 to switch between a first position and a second position. The first locking mechanism 300 is connected to the air guiding cover body 100. The air shield 200 located at the first position blocks the first channel 110 to close the first channel 110, and the air shield 200 is locked to the first locking mechanism 300; the air shield 200 located at the second position is separated from the first channel 110, and the first channel 110 can be connected to the external environment.

[0043] In the above-mentioned wind guide device, the wind shield 200 can move relative to the wind guide cover body 100 to switch between the first position and the second position. When the wind shield 200 is in the first position, it can block the first channel 110 to close the first channel 110, so that the airflow flowing out of the chassis outlet cannot flow out through the first channel 110, but all flows out through the second channel 120, thereby concentrating the air volume to cool the corresponding components at the second channel 120. And when the wind shield 200 is in the first position, it is locked in the first locking mechanism 300, thereby preventing the wind shield 200 from moving relative to the wind guide cover body 100, so that it can be stably maintained in the first position. When the wind shield 200 is in the second position, the wind shield 200 is separated from the first channel 110. At this time, the first channel 110 can be connected to the external environment. Therefore, the airflow flowing out of the chassis outlet can flow out through the first channel 110 and the second channel 120, thereby cooling the components corresponding to the first channel 110 and the second channel 120 at the same time. Therefore, the position of the wind shield 200 can be adjusted to switch between the first position and the second position, thereby changing the flow mode of the airflow to meet different heat dissipation requirements. For example, when the heat dissipation requirement of the component corresponding to the second channel 120 is high and the heat dissipation requirement of the component corresponding to the first channel 110 is low, the wind shield 200 can be adjusted to the first position; when the components corresponding to the first channel 110 and the second channel 120 both have certain heat dissipation requirements, the wind shield 200 can be adjusted to the second position.

[0044] Specifically, the above-mentioned air guide device is arranged at the air outlet on the back of the server chassis. In some embodiments, the position of the second channel 120 corresponds to the CPU and the motherboard. The CPU and the motherboard are both components with high heat dissipation requirements in the server. Therefore, the second channel 120 is always kept in an open state, and the airflow flowing out of the chassis air outlet can always flow into the external environment through the second channel 120, thereby taking away the heat generated by the CPU and the motherboard, making it less likely to overheat. The position of the first channel 110 corresponds to components such as the network card and the graphics card. If, under certain configurations, the heat dissipation requirements of such components are not high, the wind shield 200 can be adjusted to the first position to close the first channel 110. The airflow in the chassis mainly flows through the CPU and the motherboard corresponding to the second channel 120 to reach the air outlet, and then flows into the external environment through the second channel 120. If under certain configurations, the heat dissipation demand of such components increases, the wind shield 200 can be adjusted to the second position to open the first channel 110, and part of the airflow in the chassis flows through the CPU and motherboard corresponding to the second channel 120 to reach the air outlet, and flows into the external environment through the second channel 120; part of the airflow in the chassis flows through components such as the network card and graphics card corresponding to the first channel 110 to reach the air outlet, and flows into the external environment through the first channel 110.

[0045] See also Figures 1 to 3In some embodiments, the wind guide cover body 100 has a plurality of first channels 110, and the wind guide device has a plurality of wind shielding members 200 corresponding one by one to the plurality of first channels 110, each wind shielding member 200 can block the corresponding first channel 110 when located at the first position, and each wind shielding member 200 can be separated from the corresponding first channel 110 when located at the second position.

[0046] Specifically, as shown in the accompanying drawings, the wind guide cover body 100 has two second channels 120 arranged at intervals, and three first channels 110 arranged at intervals, and each second channel 120 has a first channel 110 on both sides. Each first channel 110 is provided with a corresponding wind shield 200 and a first locking mechanism 300, and each wind shield 200 is movably connected to the wind guide cover body 100, and can move relative to the wind guide cover body 100 to switch between the first position and the second position. When each wind shield 200 is in the first position, it can block the corresponding first channel 110 to close the first channel 110, and the wind shield 200 is locked to the corresponding first locking mechanism 300. When each wind shield 200 is in the second position, it can be separated from the corresponding first channel 110 so that the corresponding first channel 110 can be connected to the external environment. In other embodiments, the second channel 120 and the first channel 110 can also be set to other numbers, and the position distribution can also be set to other ways.

[0047] In the above embodiment, by providing a plurality of windshield members 200 corresponding to a plurality of first channels 110, the position of each windshield member 200 can be adjusted according to the heat dissipation requirements of the server components corresponding to each first channel 110, so that the components corresponding to each first channel 110 can be well cooled, less prone to overheating, and less prone to air volume waste. In this way, more heat dissipation requirements can be better met, and the application range of the air guide device is wider. For example, when a component corresponding to one of the first channels 110 has a higher heat dissipation requirement, the windshield member 200 corresponding to the first channel 110 can be adjusted to the second position.

[0048] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the wind shield 200 is rotatably connected to the wind guide cover body 100, and the wind shield 200 is configured to rotate relative to the wind guide cover body 100 to switch between the first position and the second position.

[0049] Specifically, the wind shield 200 is disposed on the surface of the wind guide cover body 100, and the first position and the second position are two extreme positions on the rotation path of the wind shield 200 relative to the wind guide cover body 100. The position of the wind shield 200 can be adjusted by simply rotating the wind shield 200 relative to the wind guide cover body 100, so that the first channel 110 is opened or closed to meet different heat dissipation requirements. This movement form of the wind shield 200 is simple, and the operation difficulty is relatively low, and the position adjustment of the wind shield 200 is easy to achieve.

[0050] In other embodiments, the wind shield 200 is slidably connected to the wind scoop body 100 , and the wind shield 200 is configured to slide relative to the wind scoop body 100 to switch between the first position and the second position.

[0051] Specifically, the first position and the second position are two extreme positions on the sliding path of the wind shield 200 relative to the wind scoop body 100. By sliding the wind shield 200 relative to the wind scoop body 100, the first channel 110 can be opened or closed to meet different heat dissipation requirements.

[0052] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, one of the wind shield 200 and the wind guide cover body 100 is provided with a rotation hole 131 , and the other is provided with a rotation shaft 210 , and the rotation shaft 210 is rotationally matched with the rotation hole 131 .

[0053] Specifically, in the embodiment shown in the drawings, the air guide cover body 100 is provided with a connecting plate 130 fixedly connected thereto, the connecting plate 130 is provided with a rotation hole 131, and the wind shield 200 is provided with a rotating shaft 210. The rotating shaft 210 is inserted into the rotation hole 131 and rotates with it. By rotating the rotating shaft 210 in the rotation hole 131, the wind shield 200 can be rotated relative to the air guide cover body 100. In other embodiments, the positions of the rotating shaft 210 and the rotating hole 131 can also be interchanged, that is, the rotating shaft 210 is provided on the air guide cover body 100, and the rotating hole 131 is provided on the wind shield 200.

[0054] In the above embodiment, by cooperating with the axial hole between the wind shield 200 and the wind guide cover body 100, a rotational connection between the two can be achieved, so that the wind shield 200 can rotate relative to the wind guide cover body 100 to adjust the position of the wind shield 200 to reach the first position or the second position to meet different heat dissipation requirements.

[0055] Preferably, both ends of the wind shield 200 are provided with a rotating shaft 210, and the wind guide cover body 100 is correspondingly provided with two connecting plates 130, and each connecting plate 130 is provided with a rotating hole 131. The two rotating shafts 210 are inserted into the corresponding rotating holes 131 and rotated therewith.

[0056] Specifically, the rotating shaft 210 is made of a slightly elastic material. When installing, one of the rotating shafts 210 is inserted into the corresponding rotating hole 131, and the other rotating shaft 210 is squeezed to elastically deform and inserted into the other corresponding rotating hole 131.

[0057] In the above embodiment, by providing two sets of shaft hole matching structures, the stability and smoothness of the wind shield 200 when rotating relative to the wind guide cover main body 100 can be improved.

[0058] See also Figure 1 , Figure 5 and Figure 6 In some embodiments, the first locking mechanism 300 includes a first plug-in portion 310 connected to the wind guide cover body 100, and a second plug-in portion 220 is provided on the wind shield 200. One of the first plug-in portion 310 and the second plug-in portion 220 is a slot and the other is an insert block, and the insert block can be inserted into the slot to lock the wind shield 200 in the first position.

[0059] Specifically, in the embodiment shown in the accompanying drawings, the first plug-in portion 310 is a plug-in block, and the second plug-in portion 220 is a slot. The first plug-in portion 310 is protrudingly arranged on the surface of the air scoop body 100. The first plug-in portion 310 can be integrally formed with the air scoop body 100, or fixed by means of clamping, welding, or bonding. After the plug-in block is inserted into the slot, a part of the plug-in block abuts against the slot wall of the slot to prevent the plug-in block from falling out of the slot when no external force is applied. Alternatively, after the plug-in block is inserted into the slot, the two are interference fit to prevent the plug-in block from falling out of the slot when no external force is applied. The plug-in block and the slot can be set to any shape, which is not limited here. In other embodiments, the positions of the slot and the slot can also be interchanged, that is, the second plug-in portion 220 is set as a plug-in block, and the first plug-in portion 310 is set as a slot.

[0060] In the above embodiment, the wind shield 200 that reaches the first position can be locked there by inserting the plug into the slot, so that it is not easy for the first channel 110 to open due to leaving the first position, thereby allowing the first channel 110 to remain in a closed state more stably.

[0061] Furthermore, the first plug-in portion 310 is an insert block and includes an arc portion 311 and two straight portions 312, and each end of the arc portion 311 is connected to a straight portion 312. After the insert block is inserted into the slot, the arc portion 311 abuts against the slot wall of the slot to prevent the insert block from falling out of the slot when no external force is applied.

[0062] See also Figure 1 and Figure 6In some embodiments, the first locking mechanism 300 includes a plurality of first plug-in portions 310 that are spaced apart from each other, and the wind shield 200 is provided with a plurality of second plug-in portions 220 that are plugged in and matched with the plurality of first plug-in portions 310 in a one-to-one correspondence.

[0063] Specifically, for a larger windshield 200, multiple groups of first plug-in portions 310 may be provided to lock the windshield 200. When the windshield 200 reaches the first position, each first plug-in portion 310 is plugged with a corresponding second plug-in portion 220 to prevent the windshield 200 from continuing to rotate. For a smaller windshield 200, one or more groups of first plug-in portions 310 may be provided.

[0064] In the above embodiment, the wind shield 200 can be locked therein more stably through the corresponding plug-in cooperation of the plurality of first plug-in portions 310 and the plurality of second plug-in portions 220, so that the first channel 110 can be kept in a closed state more stably.

[0065] See also Figure 1 , Figure 5 and Figure 6 In other embodiments, the first locking mechanism 300 can be snapped onto the wind shield 200 at the first position to lock the wind shield 200 at the first position.

[0066] Specifically, the first locking mechanism 300 may include a card slot, and a card block is provided on the windshield 200. The card block is inserted into the card slot to inhibit the windshield 200 from continuing to rotate, thereby locking the windshield 200 there. Alternatively, the card block and the card slot may be interchangeable, that is, the first locking mechanism 300 includes the card block, and the card slot is provided on the windshield 200. Alternatively, the position locking of the windshield 200 may also be achieved through other conventional card connection structures.

[0067] In the above embodiment, the wind shield 200 that reaches the first position can be locked there by the snap-fitting cooperation between the first locking mechanism 300 and the wind shield 200, so that it is not easy for the first channel 110 to open due to leaving the first position, thereby allowing the first channel 110 to remain in a closed state more stably.

[0068] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the wind guiding device includes a second locking mechanism 400 , and the wind shielding member 200 located at the second position can be locked to the second locking mechanism 400 .

[0069] Specifically, the second locking mechanism 400 is connected to the air scoop body 100 and is correspondingly arranged at the second position. The wind shield 200 that has reached the second position is locked there by the second locking mechanism 400, so that it is not easy to block the first channel 110 after leaving the second position and cause the first channel 110 to close, thereby allowing the first channel 110 to remain in an open state more stably.

[0070] See also Figure 1 , Figure 3 and Figure 4 In some embodiments, the second locking mechanism 400 includes a resisting member 410 connected to the wind guide cover body 100, and the resisting member 410 can resist the wind shield member 200 to lock the wind shield member 200 in the second position.

[0071] Specifically, the abutment member 410 is protrudingly disposed on the surface of the wind scoop body 100. The abutment member 410 can be integrally formed with the wind scoop body 100, or fixed by clamping, welding, or bonding. When the wind shield 200 reaches the second position, its end will abut against the abutment member 410, thereby preventing it from leaving the second position when no external force is applied.

[0072] In the above embodiment, the supporting member 410 is supported on the wind shield member 200, so that the wind shield member 200 reaching the second position can be locked there, making it difficult for it to leave the second position and block the first channel 110 to cause the first channel 110 to close, thereby allowing the first channel 110 to remain in an open state more stably.

[0073] Preferably, the second locking mechanism 400 includes a plurality of abutting members 410 protruding from the surface of the wind guide cover body 100. When the wind shield 200 reaches the second position, the plurality of abutting members 410 abut against the end of the wind shield 200 to prevent the wind shield 200 from leaving the second position when no external force is applied. By providing a plurality of abutting members 410 to abut against the wind shield 200 at the same time, the wind shield 200 can be locked therein more stably, so that the first channel 110 can be kept in an open state more stably.

[0074] In other embodiments, the second locking mechanism 400 may also adopt a structure similar to the first locking mechanism 300 to lock the position of the windshield 200 by plugging or snapping. Alternatively, the position of the windshield 200 may also be locked by snapping.

[0075] See also Figures 1 to 3 , a heat dissipation system provided in one embodiment of the present application includes the air guide device in any one of the above embodiments.
