Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the embodiments of the application.

[0045] Figure 1 Fig. 1 shows the structure diagram of the heat dissipation assembly provided by the embodiment of the application in a first working state, Figure 2 Fig. 2 shows the structure diagram of the heat dissipation assembly provided by the embodiment of the application in a second working state, Figure 3 Fig. 3 shows the structure diagram of the heat dissipation assembly provided by the embodiment of the application in a third working state, Figure 1 Fig. 4 shows the B-B sectional view of the heat dissipation assembly.

[0046] Please refer to Figures 1-3The heat dissipation assembly 100 of the present application comprises a shell; the shell comprises an outer shell 1 and an inner shell 2; along a first direction X, one end of the outer shell 1 is provided with a first air inlet 11, and the other end of the outer shell 1 is provided with an inner shell mounting port 12; a first air outlet 13 extending along the first direction X is further provided on the shell wall of the outer shell 1; along the first direction X, one end of the inner shell 2 is provided with a second air inlet 21, and the second air inlet 21 is oppositely arranged with the first air inlet 11; a second air outlet 22 extending along the first direction X is provided on the shell wall of the inner shell 2; the inner shell 2 is sleeved in the outer shell 1, along a second direction Y, the first air outlet 13 and the second air outlet 22 at least partially overlap to form an air outlet overlapping portion, the first air outlet 13 exposes at least part of the second air outlet 22, and the first direction X intersects with the second direction Y; the heat dissipation assembly 100 comprises a first working state and a second working state, in the first working state, the width of the air outlet overlapping portion along the first direction is L1; in the second working state, the width of the air outlet overlapping portion along the first direction is L2, wherein L1>L2.

[0047] Specifically, please continue to refer to Figure 1 and Figure 3 As shown in Figure 1 , when the heat dissipation assembly 100 is in the first working state, the inner shell 2 is located in the outer shell 1; at this time, along the first direction X, the first air outlet 13 and the second air outlet 22 have the maximum overlapping width, in some embodiments of the present application, if the width of the first air outlet 13 is a1, and the width of the second air outlet 22 is a2, when a1 is less than a2, the air outlet width of the heat dissipation assembly 100 at this time is a1; if a1 is greater than a2, then the air outlet width of the heat dissipation assembly 100 is a2.

[0048] Please refer to Figure 2 , as shown in Figure 2 , when the heat dissipation assembly 100 is in the second working state, at least part of the inner shell 2 is located outside the outer shell 1 along the first direction X; at this time, along the first direction X, the overlapping width of the first air outlet 13 and the second air outlet 22 is smaller than that of the structure shown in Figure 1 ; in some embodiments of the present application, the overlapping width of the first air outlet 13 and the second air outlet 22 is very small, so the air outlet width of the heat dissipation assembly 100 at this time is approximately the sum of the widths of the first air outlet 13 and the second air outlet 22.

[0049] Then, along the first direction X, when a smaller heat dissipation width is needed, the inner shell 1 is located in the outer shell 2, and the first air outlet 13 and the second air outlet 22 have the maximum overlapping width; when a larger heat dissipation width is needed, the inner shell 1 can be moved relative to the outer shell 2, and the first air outlet 13 and the second air outlet 22 have the minimum overlapping width, so that the width of the overall air outlet of the heat dissipation assembly 100 can be increased.

[0050] It should be noted that, Figure 1 Figure 2 The two different working states of the heat dissipation assembly 100 are only schematic, and the heat dissipation assembly 100 can not have only the two working states; wherein, Figure 1 The first working state of the heat dissipation assembly 100 can be regarded as a schematic diagram; Figure 2 The second working state of the heat dissipation assembly 100 can be regarded as a schematic diagram; along with the change of the width of the air outlet overlapping part in the first direction, the working state of the heat dissipation assembly 100 also includes a plurality of intermediate working states between Figure 1 Figure 2 The working states shown in the working states are not limited by the present application.

[0051] In summary, the heat dissipation assembly 100 of the present application can adjust the overlapping width of the first air outlet 13 and the second air outlet 22 along the first direction X according to the required heat dissipation width of the object to be cooled, so that the air outlet width of the heat dissipation assembly 100 is suitable for the required heat dissipation width of the object to be cooled, so that the air outlet of the heat dissipation assembly 100 can be more effectively applied, and the phenomenon of cold air waste caused by the air outlet width of the heat dissipation assembly 100 being greater than the required heat dissipation width of the object to be cooled can be avoided, so as to improve the cold air utilization rate of the heat dissipation device; on the other hand, the heat dissipation assembly 100 of the present application includes an inner shell 1 and an outer shell 2, and the inner shell 1 can be located in the outer shell 2, so that under the condition that the heat dissipation assembly 100 does not work, or in the case that the required heat dissipation width of the object to be cooled is small, the space occupied by the heat dissipation assembly 100 is small, which is suitable for carrying or placing; thirdly, the structure of the heat dissipation assembly 100 of the present application is independent, and can not depend on the object to be cooled, which is a relatively independent assembly, so it is convenient to assemble or maintain.

[0052] In addition, it should be noted that along the first direction X, the second air inlet 21 is arranged at one end of the inner shell 2 close to the first air inlet 11, and the other end of the inner shell 2 opposite to the position of the second air inlet 21 can be provided with a sealing structure 24 for end sealing, so that the cold air can only be blown out from the second air outlet 22 of the inner shell 2, avoiding the loss of wind power.

[0053] It should also be noted that, Figure 3 Figure 4 and Figure 4 Only one specific embodiment of the heat dissipation assembly 100 of the present application is given, which is intended to illustrate the cooperation relationship of the air outlets of the outer shell 1 and the inner shell 2 of the heat dissipation assembly 100, and is not as a constraint or limitation on the shape of the outer shell 1 or the shape of the inner shell 2.

[0054] Figure 4 ​​​The diagram shown is a structural diagram of the heat dissipation component provided in the embodiment of the present invention in its first working state; please refer to... Figure 4 The first air inlet 11 of the outer casing 1 includes a perforated plate, which includes a central region and an edge region surrounding the central region. The central region is provided with a central hole 111, and the edge region is provided with a plurality of edge holes at least partially surrounding the central hole. The width of the central hole 111 along the first direction X is greater than the width of the edge holes along the first direction X. In some optional embodiments, the edge holes include a first edge hole 112 and a second edge hole 113. The first edge hole 112 is located on the side of the second edge hole 112 closer to the central hole 111, and the width of the first edge hole 112 along the first direction X is greater than the width of the second edge hole 112 along the first direction X.

[0055] Please continue to refer to this. Figure 2 ,exist Figure 4 In the structure shown, the width of the central hole 111 along the first direction X is greater than the width of the edge hole along the first direction X. Specifically, a perforated plate is provided at one end of the outer shell 1 along the first direction X. Along the first direction X, the perforated plate includes a central region and an edge region surrounding the central region. The central region is provided with the central hole 111, and the edge region is provided with a first edge hole 112 and a second edge hole 113 surrounding the central hole 111. The first edge hole 112 is closer to the central hole 111 than the second edge hole 113, and the central hole 111 has the largest cross-sectional area, while the second edge hole 113 has the smallest cross-sectional area. In this embodiment, the central hole 111, the first edge hole 112 surrounding the central hole 111, and the second edge hole 113 together form the first air inlet 11 of the heat dissipation assembly 100. Cold air is sent into the outer shell 1 through the first air inlet 11 from the outside of the outer shell 1. Since the central hole 111 has the largest cross-sectional area, the air volume passing through the central hole 111 is the largest. Since the second edge hole 113, which is relatively far from the central hole 111, has the smallest cross-sectional area, the air volume entering the outer shell from the second edge hole 113 is the smallest. Thus, the air volume is larger closer to the center of the perforated plate and smaller closer to the edge of the perforated plate. Therefore, along the direction perpendicular to the first direction X, the air volume is concentrated towards the center of the outer shell 1. Consequently, the air volume entering the outer shell 1 from the first air inlet 11 has a larger wind force in the center of the outer shell 1, and therefore, the distance the wind is transmitted is farther.

[0056] In some embodiments of the present invention, such as Figure 5As shown, along the first direction X, when the inner casing 2 extends a long distance relative to the outer casing 1, the overlapping width of the first air outlet 13 and the second air outlet 22 is very small, at this time, the air outlet width of the heat dissipation assembly 100 is about the sum of the width of the first air outlet 13 and the width of the second air outlet 22, that is, the width of the air outlet of the heat dissipation assembly 100 in this state is relatively wide; since the air entering the outer casing 1 from the first air inlet 11 continuously flows out from the air outlet of the heat dissipation assembly 100 during transmission, the farther away from the first air inlet 11, the smaller the air volume, and the second air outlet 22 of the heat dissipation assembly 100 far away from the first air inlet 11 is prone to air volume shortage; the present application adopts a hole plate structure at one end of the first air inlet 11 of the heat dissipation assembly 100, and uses the hole plate structure to strengthen the air volume of the central region of the outer casing 1, so that to a certain extent, the air force of the central region of the outer casing 1 can be increased, so as to ensure the air volume of the second air outlet 22 far away from the first air inlet 11, so that the cold air is released in the entire width range of the second air outlet 22, so as to better meet the heat dissipation requirement.

[0057] It should be noted that, Figure 2 The hole plate shown in the figure is only one embodiment of the present application, and does not limit the hole plate structure of the present application, for example, the shape of the hole can be circular or other special shapes; the edge hole around the center hole 111 can be one circle, two circles or other numbers.

[0058] Figure 3 The structure of the inner casing provided by the embodiment of the present application is shown in the figure, please combine it with the figures, Figure 5 , Figure 1 and Figure 2 The inner casing 2 further comprises an inner air duct 23; along the first direction X, the inner air duct 23 is in communication with the second air outlet 22; the inner air duct 23 comprises a first end 23A and a second end 23B arranged oppositely, the first end 23A is located on the side of the second end 23B close to the first air inlet 11; the cross-sectional area of the first end 23A along the second direction Y is greater than the cross-sectional area of the second end 23B along the second direction Y.

[0059] Specifically, please combine Figure 3 , Figure 5 , Figure 6 and Figure 5As mentioned above, the farther away from the first air inlet 11, the smaller the air volume; especially when the air outlet width of the heat dissipation assembly 100 is wide, the second air outlet 22 of the heat dissipation assembly 100 far away from the first air inlet 11 is prone to insufficient air volume; based on this, the inner air duct 23 is arranged in the inner shell 2 of the present application; the inner air duct 23 is in communication with the second air outlet 22; the inner air duct 23 includes the first end 23A and the second end 23B arranged oppositely, and the first end 23A is located on the side of the second end 23B close to the first air inlet 11; the cross-sectional area of the first end 23A along the second direction Y is larger than that of the second end 23B along the second direction Y; in some preferred embodiments of the present application, along the first direction X, from the first end 23A to the second end 23B, the cross-sectional area of the inner air duct 23 along the direction perpendicular to the first direction X is gradually reduced; since the air pressure is proportional to the air volume and inversely proportional to the cross-sectional area, the reduction of the cross-sectional area helps to increase the air pressure, so that the inner air duct 23 with the gradually reduced cross-sectional area along the first direction X from the first end 23A to the second end 23B can compensate for the reduction of the air volume to a certain extent, so that the cold air with a certain air force is released in the entire width range of the second air outlet 22, so as to better meet the heat dissipation requirements.

[0060] Figure 6 The figure shows a schematic view of a component of an inner air duct provided by an embodiment of the present application; please refer to Figure 2 and Figure 3 In some optional embodiments of the present application, the inner air duct 23 includes the first baffle 231 and the second baffle 232 arranged oppositely along the third direction Z; the third direction Z intersects the first direction X, and the third direction Z intersects the second direction Y; the first baffle 231 includes the first surface a facing the second baffle 232, the second baffle 232 includes the second surface β facing the first baffle 231, and the included angle between the plane where the first surface a is located and the plane where the second surface β is located is γ, wherein 0°<γ<90°; the second air outlet 22 at least partially does not overlap with the first baffle 231 along the second direction Y, and the second air outlet 22 at least partially does not overlap with the second baffle 232 along the second direction Y.

[0061] Specifically, please refer to Figure 4 and combine with Figure 5 , Figure 6 , Figure 6 and Figure 7In some embodiments of the present application, when the inner casing 2 extends a long distance relative to the outer casing 1, the overlapping width of the first air outlet 13 and the second air outlet 22 is very small; the distance between the other end of the inner casing 2 (the distal end of the inner casing 2) opposite to the second air inlet 21 and the first air inlet 11 is relatively long, at this time, the cold air enters the outer casing 1 from the first air inlet 11, and when the cold air is transmitted towards the distal end of the inner casing 2 under the action of air pressure, the cold air is continuously blown out from the first air outlet 13 and the second air outlet 22 in the process of transmission, therefore, the closer to the distal end of the inner casing 2, the smaller the air volume of the corresponding position of the inner casing 2. Based on this, please refer to Figs. 5 and Figure 7 The present application adds the first baffle 231 and the second baffle 232 in the inner casing 2, the first baffle 231 includes a first surface a towards the second baffle 232, the second baffle 232 includes a second surface β towards the first baffle 231, the included angle between the plane where the first surface a is located and the plane where the second surface β is located is γ, wherein 0°<γ<90°, the purpose of setting the first baffle 231 and the second baffle 232 is to make the air duct in the inner casing 2 narrower and narrower towards the second end 23B of the inner casing, based on the similar reasons as mentioned above, the narrower and narrower air duct is beneficial to make up for the loss of air volume, improve air pressure, and make the cold air be able to be smoothly transmitted to the distal end of the inner casing 2 of the inner casing 2; in this way, the air outlet 22 at the distal end of the inner casing 2 can blow out the cold air with a certain air force to meet the demand of the overall air outlet width of the heat dissipation assembly 100.

[0062] In some optional embodiments of the present application, the value range of γ can be 8°<γ<30°; specifically, the value of γ is related to the length of the inner air duct 23, the shape of the inner air duct 23 and other factors, and can be adjusted according to actual needs.

[0063] Figure 7 Fig. 4 shows the application structure schematic diagram of the heat dissipation device provided by the embodiment of the present application, please refer to Figure 1 In some embodiments of the present application, the heat dissipation assembly 100 further includes the air blower 6, and the air blower 6 is located on the side of the first air inlet 11 away from the inner casing mounting port 12.

[0064] Please continue to refer to Figure 3 In the present application, the side of the first air inlet 11 away from the inner casing mounting port 12 needs to have the air blower 6, in this way, the cold air blown out from the air blower 6 enters the outer casing 1 and the inner casing 2 through the first air inlet 11, and in the process of transmission in the outer casing 1 and the inner casing 2, the cold air is released from the first air outlet 13 and the second air outlet 22 to dissipate heat to the object to be cooled, such as the display panel 200. In some embodiments of the present application, the air blower 6 can be a blower or a fan.

[0065] Please continue to refer to Figure 4 ,Figure 5 、 Figure 6 、 Figure 1 and Figure 3 In some optional embodiments of the present application, along the first direction X, the first end 23A of the inner air duct 23 comprises a third air inlet 25, which is in communication with the first air inlet 11; the third air inlet 25 comprises a wind blocking part, which comprises a first wind blocking part 233 connected with the first baffle 231, a second wind blocking part 234 connected with the second baffle 232, and at least one of the inner shell 2 and the outer shell 1 abutting against the wind blocking part to form the third air inlet 25.

[0066] Please continue to refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 3 and Figure 4 In some specific embodiments of the present application, along the first direction X, both ends of the first baffle 231 and the second baffle 232 are located at both ends of the inner shell 2; along the second direction Y, both ends of the first baffle 231 and the second baffle 232 extend to the shell wall of the inner shell 2 respectively; the end of the first baffle 231 and the second baffle 232 close to the first air inlet 11 and the shell wall of the inner shell 2 along the second direction Y enclose the third air inlet 25; along the third direction Z, the first baffle 231 and the second baffle 232 are located on both sides of the second air outlet 22. In some other embodiments of the present application, the first wind blocking part 233 and the second wind blocking part 234 are located on the outside of the inner shell 2, and the first wind blocking part 233 and the second wind blocking part 234 are in contact with the outer shell 1 to form the third air inlet 25, at this time, the shape of the third air inlet 25 is similar to the shape of a horn mouth.

[0067] When the heat dissipation assembly 100 is working, cold air enters the outer shell 1 from the first air inlet 100, and during the transmission along the first direction X, the cold air is continuously blown out from the first air outlet 11; when the cold air is transmitted to the inner shell 2, it will enter the inner air duct 23 from the third air inlet 25, and during the transmission in the inner air duct 23, the cold air will be blown out from the corresponding second air outlet 22.

[0068] Please continue to refer to Figure 5 、 Figure 6 、 Figure 1 and Figure 2 The present application is provided with the first wind blocking part 233 and the second wind blocking part 234, so that the cold air can be prevented from flowing out from the gap between the inner air duct 23 and the shell wall of the inner shell 2, and the cold air can be made to enter the inner air duct 23 from the third air inlet 25, so as to strengthen the air power in the inner air duct 23.

[0069] It should be noted that the first wind blocking part 233 and the first baffle 231 in the present application can be a split structure, and the two are fixedly connected through screws or the like; the first wind blocking part 233 and the first baffle 231 can also be an integral structure, and are integrally formed through injection molding, sheet metal or the like, having a natural connection relationship; similarly, the second baffle 232 and the second wind blocking part 234 can be a split structure, and are fixedly connected; the second baffle 232 and the second wind blocking part 234 can also be an integral structure; the present application does not limit this.

[0070] It should also be noted that the inner air duct 23 in the embodiment of the present application only adds the first baffle 231 and the second baffle 232 in the inner shell 2, so as to play a role in gathering wind power and making up for insufficient wind power, and has the characteristics of simple structure and easy implementation. Although the embodiment of the present application only provides a composition structure of the inner air duct 23, the implementation mode of the inner air duct 23 of the present application is not limited to the structure given in the embodiment of the present application, and any other structure that can play a role in gathering wind power can be applied to the present application, such as a split structure given in the embodiment of the present application, or a whole structure such as a cylindrical structure, and the cross section can be polygonal, circular or other irregular shapes.

[0072] Specifically, please continue to refer to Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 8Since the display panel 200 has a certain height in the second direction Y, in order to increase the heat dissipation uniformity of the display panel 200 in the first direction Y as much as possible, the air outlet adjusting structure is arranged at the first air outlet 13 and / or the second air outlet 22, so that the air outlet adjusting structure 3 at the first air outlet 13 and / or the second air outlet 22 can be deflected by adjusting, the air pressure and the air direction of the first air outlet 13 and / or the second air outlet 22 are changed, so that the air of the first air outlet 13 and / or the second air outlet 22 can be blown far away, so as to cool the upper part of the display panel; the first air outlet 13 and / or the second air outlet 22 can also be blown close to the lower end of the display panel for rapid cooling. Therefore, the heat dissipation assembly 100 with the air outlet adjusting structure can adjust the air direction and the air pressure according to the heat dissipation area of the object to be cooled, so that the object to be cooled can be cooled more uniformly along the second direction Y, and the phenomenon of local temperature being too low or local temperature being too high is avoided, and the working reliability of the object to be cooled is improved.

[0073] Figure 8 Fig. 1 shows a structure diagram of an air outlet adjusting structure of a heat dissipation assembly according to an embodiment of the present application, please refer to Figure 8 In some optional embodiments of the present application, the first air outlet 13 includes opposite first and second side walls 131 and 132 along the third direction Z, and the air outlet adjusting structure 3 is located at least at the first air outlet 13; the third direction Z intersects the first direction X and the second direction Y; the heat dissipation assembly 100 includes a driving assembly, and the air outlet adjusting structure 3 is deflected towards or away from the first side wall 131 under the action of the driving assembly.

[0074] Specifically, please continue to refer to Figure 8 In some embodiments of the present application, the first air outlet 13 is located on the shell wall of the outer shell 1, specifically, the first air outlet 13 is an opening on the outer shell 1, and the opening extends along the first direction X; along the third direction Z, the first air outlet 13 is formed by the gap between the first and second side walls 131 and 132, and the air outlet adjusting structure 3 can be located at least at the first air outlet 13; in some embodiments of the present application, the air outlet adjusting structure 3 also extends along the first direction X, and the length of the air outlet adjusting structure 3 along the first direction X is approximately the same as the length of the first air outlet 13 along the first direction X.

[0075] Please continue to refer to Figure 8 , Figure 8The display panel 200 in the figure is a heat dissipation object, and the heat dissipation object can also be other devices; in order to make the air force relatively concentrated, the air outlet adjusting structure 3 of the present application is generally arranged close to the second side wall 132, and the heat dissipation object, such as the display panel 200, is arranged on the shell on the side of the first side wall 131. In this way, the gap between the air outlet adjusting structure 3 and the first side wall 131 becomes the main air outlet part of the first air outlet 13.

[0076] The present application adjusts the size of the main air outlet part of the first air outlet 13 through the air outlet adjusting structure 3 arranged at least at the first air outlet 13, which is deflected towards or away from the first side wall 131 under the action of the driving assembly. In this way, the size of the main air outlet part of the first air outlet 13 can be adjusted through the air outlet adjusting structure 3. Figure 8 As shown in the figure, when the air outlet adjusting structure 3 is deflected towards the first side wall 131, the gap between the air outlet adjusting structure 3 and the first side wall 131 is reduced, and the included angle between the air outlet adjusting structure 3 and the first side wall 131 is also reduced. At this time, the air pressure is enhanced, and the wind blows lower in the third direction Z, so that the cooling part is mainly concentrated in the area close to the first air outlet 13 of the heat dissipation object. When the air outlet adjusting structure 3 is deflected away from the first side wall 131, the gap between the air outlet adjusting structure 3 and the first side wall 131 is increased, and the included angle between the air outlet adjusting structure 3 and the first side wall 131 is also increased. At this time, the air pressure is relatively reduced, and the wind blows higher in the third direction Z, so that the cooling part covers the area away from the first air outlet 13 of the heat dissipation object. In this way, the present application can heat the area close to the first air outlet 13 of the heat dissipation object and the area away from the first air outlet 13 of the heat dissipation object through the air outlet adjusting structure 3 arranged at least at the first air outlet 13, so as to improve the working reliability of the heat dissipation object.

[0077] Please continue to refer to Figure 9 In some optional embodiments of the present application, the air outlet adjusting structure 3 includes a first air outlet adjusting structure 31 and a second air outlet adjusting structure 32, the first air outlet adjusting structure 31 is arranged corresponding to the first air outlet 13, and the second air outlet adjusting structure 32 is arranged corresponding to the second air outlet 22; along the third direction Z, the second air outlet 22 includes opposite third and fourth side walls 133 and 134, the first air outlet adjusting structure 31 is at least partially located between the first and second side walls 131 and 132, the second air outlet 22 is at least partially located between the third and fourth side walls 133 and 134, and the second air outlet adjusting structure 32 is located between the first air outlet adjusting structure 31 and the third side wall 133, and at least one of the first and second air outlet adjusting structures 31 and 32 is connected with the driving assembly.

[0078] Specifically, please continue to refer to Figure 9The application is provided with air outlet adjusting structures 3 at the first air outlet 13 and the second air outlet 22, the first air outlet adjusting structure 31 is located at least partially between the first side wall 131 and the second side wall 132, and the second air outlet adjusting structure 32 is located between the first air outlet adjusting structure 31 and the third side wall 133. In this way, no matter whether the inner shell 2 is located in the outer shell 1 or the inner shell 2 is extended relative to the outer shell 1, and no matter whether the first air outlet 13 and the second air outlet 22 overlap in the first direction, the air pressure and the air direction at the first air outlet 13 and the second air outlet 22 can be adjusted for the whole heat dissipation assembly 100. In this way, the air pressure and the air direction can be adjusted according to the heat dissipation requirement of the object to be cooled, so as to ensure the appropriate working temperature of the object to be cooled.

[0079] Figure 1 Fig. 1 shows the installation schematic diagram of the first air outlet adjusting structure provided by the embodiment of the application, please refer to Figure 2 , and combine Figure 10 with Figure 10 , the first air outlet adjusting structure 31 of the application can be plate-shaped, and a rotating shaft 31A is fixedly arranged at one end of the first air outlet adjusting structure 31 close to the first air outlet 11. The driving assembly 7 is arranged in the outer shell 1, and the driving assembly 7 can drive the rotating shaft 31A to rotate, so that the deflection of the first air outlet adjusting structure 31 can be realized.

[0080] Figure 8 Fig. 2 shows the linkage structure schematic diagram of the first air outlet adjusting structure and the second air outlet adjusting structure provided by the embodiment of the application; please refer to Figure 9 In some optional embodiments of the application, the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 include a linkage structure 33, the linkage structure 33 includes a recess 331 and a protrusion 332 which are mutually embedded, the recess 331 is arranged in one of the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, and the protrusion 332 is arranged in the other one of the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32.

[0081] Specifically, please combine Figure 10 , Figure 11 with Figure 11In some optional embodiments of the present application, the linkage structure 33 is arranged on the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, the linkage structure 33 comprises the recess 331 and the protrusion 332 which are mutually embedded, thus, when the first air outlet adjusting structure 31 is deflected, the second air outlet adjusting structure 32 is deflected along with the first air outlet adjusting structure 31, thus, when the driving of the air outlet adjusting structure 3 is performed, the first air outlet adjusting structure 31 or the second air outlet adjusting structure 32 can be driven only; therefore, the present application can reduce the number of driving assemblies by arranging the linkage structure 33 on the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, and the structure of the heat dissipation assembly 100 is simpler, and the heat dissipation assembly 100 is more energy-saving.

[0082] Figure 10 Another linkage structure of the first air outlet adjusting structure and the second air outlet adjusting structure is shown in the figure; in some optional embodiments of the present application, the heat dissipation assembly 100 comprises the linkage structure 33, the linkage structure comprises the guide rail 333 and the recess, the recess comprises the first recess 334 of the first air outlet adjusting structure 31 and the second recess 335 of the second air outlet adjusting structure 32, the guide rail 333 is located between the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, and the first recess 334 and the second recess 335 are embedded with the guide rail 333 respectively.

[0083] Please continue to refer to Figure 11 , based on the similar reasons as mentioned above, the linkage structure 33 is arranged on the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, and the first air outlet adjusting structure 31 or the second air outlet adjusting structure 32 can be driven only when the driving of the air outlet adjusting structure 3 is performed; therefore, the present application can reduce the number of driving assemblies by arranging the linkage structure 33 on the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, and the structure of the heat dissipation assembly 100 is simpler, and the heat dissipation assembly 100 is more energy-saving.

[0084] In addition, in some embodiments of the present application, Figure 9 The main body of the first air outlet adjusting structure 31 shown in Figure 10 The main body of the second air outlet adjusting structure 32 shown in is a rectangular plate; along the first direction, Figure 10 The recess 331, the protrusion 332 and Figure 11The first groove 334 and the second groove 335 shown in the figure extend from one end of the rectangular plate to the other end of the rectangular plate, so that the protrusion 332 can be inserted into the first groove from one end of the first groove 331, facilitating the matching installation of the groove 331 and the protrusion 332; similarly, facilitating the matching installation of the first groove 334 and the second groove 335 and the guide rail 333. In some embodiments of the application, the groove 331, the first groove 334 and the second groove 335 are dovetail grooves, which have the characteristics of simple processing on the one hand, and on the other hand, the dovetail groove and the dovetail-shaped protrusion matched therewith have relatively good engagement force, which can prevent the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 from being forcibly rotated during rotation.

[0085] In addition, please continue to refer to Figure 12 or Figure 9 In the case of the linkage structure 33 provided on the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32, the motor included in the driving assembly can be one or two. When the number of motors is 1, the motor has two functions of forward rotation and reverse rotation. When the motor rotates in the forward direction, the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 deflect in one direction; when the motor rotates in the reverse direction, the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 deflect in the other direction.

[0086] Figure 10 The figure shows a structure schematic diagram of a driving assembly provided by an embodiment of the application. Please refer to Figure 11 and Figure 12 or Figure 8 and Figure 12 When the number of motors in the driving assembly 7 is 2, the driving assembly 7 includes a first motor 41 and a second motor 42. The first motor 41 only deflects in the forward direction, and the first motor 41 is connected with the first air outlet adjusting structure 31 to drive the first air outlet adjusting structure 31 to deflect toward the first side wall 131. The second air outlet adjusting structure 32 deflects toward the first side wall 131 together with the first air outlet adjusting structure 31 under the action of the linkage structure 33. The second motor 42 only deflects in the reverse direction, and the second motor 42 is connected with the second air outlet adjusting structure 32 to drive the second air outlet adjusting structure 32 to deflect away from the first side wall 131. The first air outlet adjusting structure 31 deflects away from the first side wall 131 together with the second air outlet adjusting structure 32 under the action of the linkage structure 33.

[0087] Please refer to Figure 1 and Figure 2In some optional embodiments of the present application, the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 can also be linked together in the case that no linkage structure 33 is additionally added on the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32. The specific implementation structure is as follows: along the third direction Z, the first air outlet adjusting structure 31 is located at the side of the second air outlet adjusting structure 32 facing the first side wall 131, and the second air outlet adjusting structure 32 is in contact with the first air outlet adjusting structure 31; the driving assembly 7 comprises a first motor 71 and a second motor 72, the first motor 71 is connected with the first air outlet adjusting structure 31, and the second motor 72 is connected with the second air outlet adjusting structure 32. In this way, when the first motor 71 works and the second motor 72 does not work, the first motor 71 drives the first air outlet adjusting structure 31 to deflect towards the first side wall 131, and since the second air outlet adjusting structure 32 is located at the side of the first air outlet adjusting structure 31 facing the first side wall 131, the second air outlet adjusting structure 32 also deflects towards the first side wall 131 under the action of the first air outlet adjusting structure 31; when the second motor works and the first motor does not work, the second motor drives the second air outlet adjusting structure 32 to deflect away from the first side wall, and since the first air outlet adjusting structure 31 is located at the side of the second air outlet adjusting structure 32 away from the first side wall, the first air outlet adjusting structure 31 also deflects away from the first side wall under the action of the second air outlet adjusting structure 32. In this embodiment, the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 not only have simple structure, but also only need to start one motor of the driving assembly when adjusting the air direction, and the other motor can not work, so that the energy consumption is saved, and the noise is smaller during heat dissipation.

[0088] In some optional embodiments of the present application, the driving assembly comprises a first driving assembly and a second driving assembly, the first driving assembly is connected with the first air outlet adjusting structure 31, and the second driving assembly is connected with the second air outlet adjusting structure 32.

[0089] Specifically, please continue to refer to Figure 8 , Figure 11 , Figure 12 and Figure 13 , Figure 8In some embodiments of the present application, the driving assembly comprises a first driving assembly and a second driving assembly, wherein the first driving assembly is connected with the first air outlet adjusting structure 31, and the second driving assembly is connected with the second air outlet adjusting structure 32; in this way, the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 can be adjusted independently in the case that the deflection between the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 has no linkage relationship; at this time, the first driving assembly and the second driving assembly can drive the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 to deflect synchronously, or the deflection angles of the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 can be inconsistent according to the heat dissipation requirements of the heat dissipation object; generally speaking, since the second air outlet 22 is far away from the first air inlet 11, in some embodiments of the present application, the gap between the second air outlet adjusting structure 32 and the first side wall 131 will be smaller in the case of the same deflection direction. Therefore, by setting the first driving assembly connected with the first air outlet adjusting structure 31 and the second driving assembly connected with the second air outlet adjusting structure 32, the present application can flexibly adjust the air pressure and the air direction at the first air outlet 13 and the second air outlet 22, and more easily meet the heat dissipation requirements of the heat dissipation object.

[0090] In some optional embodiments of the present application, the heat dissipation assembly 100 comprises a third working state, in which the plane where the first air outlet adjusting structure 31 is located and the plane where the second air outlet adjusting structure 32 is located comprise an air adjusting included angle θ, 0 < θ < 90°.

[0091] Figure 13As shown in the structural schematic view of the air outlet adjusting structure of the heat dissipation assembly provided by the embodiment of the present application, in some embodiments of the present application, the angle formed between the surface of the first air outlet adjusting structure 31 close to the display panel 200 (the heat dissipation object) and the surface of the display panel 200 close to the first air outlet adjusting structure 31 is ∠C; the angle formed between the surface of the second air outlet adjusting structure 32 close to the display panel 200 (the heat dissipation object) and the surface of the display panel 200 close to the second air outlet adjusting structure 32 is ∠D, and ∠D is smaller than ∠C, and the difference between ∠D and ∠C is equal to the air adjusting angle θ between the plane where the first air outlet adjusting structure 31 is located and the plane where the second air outlet adjusting structure 32 is located. By including the air adjusting angle θ between the plane where the first air outlet adjusting structure 31 is located and the plane where the second air outlet adjusting structure 32 is located, the present application can make the angle formed between the surface of the first air outlet adjusting structure 31 close to the display panel 200 (the heat dissipation object) and the surface of the display panel 200 close to the first air outlet adjusting structure 31 relatively large, and the angle formed between the surface of the second air outlet adjusting structure 32 close to the display panel 200 (the heat dissipation object) and the surface of the display panel 200 close to the second air outlet adjusting structure 32 relatively small, so that the air force at the second air outlet adjusting structure 32 can be compensated to some extent, and the phenomenon of insufficient air force at the second air outlet adjusting structure 32 can be avoided, so as to better ensure the heat dissipation effect of the heat dissipation object.

[0092] Please continue to refer to Figure 8 and Figure 13 In some optional embodiments of the present application, the heat dissipation assembly 100 further includes a sealing element 4 for sealing the gap between the air outlet adjusting structure 3 and one side wall of the first air outlet 13; and / or, the sealing element 4 is used for sealing the gap between the air outlet adjusting structure 3 and one side wall of the second air outlet 22.

[0093] Specifically, please continue to refer to Figure 8 and Figure 13 In some optional embodiments of the present application, in order to enable the air outlet adjusting structure 3 to normally flip and not interfere with the side wall at the first air outlet 13 and / or the second air outlet 22, the air outlet adjusting structure 3 and the side wall have a certain gap therebetween; for example, Figure 14 and Figure 15As shown, the gaps between the first air outlet adjustment structure 31 and the second side wall 132, and between the second air outlet adjustment structure 32 and the fourth side wall 134, are both air leakage gaps. To prevent air from blowing out of these gaps and affecting heat dissipation, the present invention provides a first sealing element 41 at the first air outlet adjustment structure 31 and a second sealing element 42 at the second air outlet adjustment structure. The first sealing element 41 seals the gap between the first air outlet adjustment structure 31 and the second side wall 132, and the second sealing element 42 seals the gap between the second air outlet adjustment structure 32 and the fourth side wall 134. Thus, by providing sealing elements at the air leakage gaps, the present invention can prevent air leakage at these gaps, thereby ensuring effective airflow at the first air outlet 13 and the second air outlet 22, ensuring heat dissipation, and improving cooling efficiency.

[0094] Figure 14 The diagram shown is a structural schematic of the air outlet adjustment structure of a heat dissipation component provided in an embodiment of the present invention. Figure 16 yes Figure 14 Top view of area A in the middle. Figures 14 to 16 yes Figures 14 to 16 A schematic diagram of an air outlet adjustment structure is provided below; please refer to it. Figure 15 Along the third direction Z, the first air outlet adjustment structure 31 and / or the second air outlet adjustment structure 32 are provided with protrusions 3A on the surface near the first sidewall 131.

[0095] For details, please refer to [link / reference]. Figure 16 In the heat dissipation assembly 100 of the present invention, protrusions 3A are provided on the surfaces of the first air outlet adjustment structure 31 and / or the second air outlet adjustment structure 32 near the first sidewall 131 along the third direction Z; therefore, the distance between the first air outlet adjustment structure 31 and the second air outlet adjustment structure 32 and the first sidewall 131 is reduced along the third direction Z due to the presence of the protrusions 3A; furthermore, please refer to Figure 14 and Figure 15 The protrusions 3A can be arranged in a row along the first direction X at the first air outlet adjustment structure 31 and the second air outlet adjustment structure 32. Then, at the position where the protrusions 3A are arranged along the first direction X, the airflow is relatively strong, which can achieve the effect of local airflow enhancement at the first air outlet 13 or the second air outlet 22, thereby accelerating the heat dissipation of the display panel 200.

[0096] Furthermore, in some embodiments of the present invention, protrusions 3A may be provided on the surfaces of the first air outlet adjustment structure 31 and the second air outlet adjustment structure 32 near the first side wall 131, or protrusions 3A may be provided only on the surface of the second air outlet adjustment structure 32 near the first side wall 131. In this way, the phenomenon of reduced airflow caused by the second air outlet 22 being far away from the first air inlet 13 can be compensated.

[0097] It needs to be explained that, Figure 16 , Figure 1 and Figure 2 Only the example that the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 are provided with a row of protrusions 3A near the surface of the first side wall 131 is given, and in specific applications, the protrusions 3A can be provided as two rows or more rows according to the size of the first air outlet 13 and the second air outlet 22 and the air force of the air blower.

[0098] Please combine Figure 5 , Figure 1 and Figure 2 In some optional embodiments of the present application, the inner shell 2 and the outer shell 1 further comprise a sliding structure 5 extending along the first direction X; the sliding structure 5 comprises a sliding rail and a sliding groove 51 in sliding cooperation with each other, the sliding rail is arranged on one of the outer wall of the inner shell 2 and the inner wall of the outer shell 1, and the sliding groove 51 is arranged on the other one of the outer wall of the inner shell 2 and the inner wall of the outer shell 1.

[0099] Specifically, please continue to refer to Figure 5 , Figure 1 and Figure 2 In some optional embodiments of the present application, the inner shell 2 and the outer shell 1 are connected through the sliding structure 5, so that when the object to be cooled needs a smaller cooling width, the inner shell 2 can be nested in the outer shell 1, at this time, as shown in Figure 2 , the air outlet width of the cooling assembly 100 is the width of the first air outlet 13; when the object to be cooled needs a wider cooling width, the inner shell 2 can slide out to the outside of the outer shell 1 through the sliding structure 5, at this time, as shown in Figure 5 , the air outlet width of the cooling assembly 100 is approximately equal to the sum of the width of the first air outlet 13 and the width of the second air outlet 22; in addition, when the air outlet width of the cooling assembly 100 needs to be narrowed, the inner shell 22 can also slide into the outer shell 1 through the sliding structure 5; the present application changes the air outlet width of the cooling assembly 100 by sliding the inner shell 2, in this process, the sliding structure 5 mainly plays a role in reducing the friction between the inner shell 2 and the outer shell 1, and also plays a guiding role. Therefore, by arranging the sliding structure 5 between the inner shell 2 and the outer shell 1 of the cooling assembly 100, the present application can make the adjustment of the air outlet width of the cooling assembly 100 easier and more accurate; in addition, the present application sets the sliding structure by means of the inner wall of the outer shell 1 and the outer wall of the inner shell 2, which has the characteristic of simple structure.

[0100] It needs to be explained that, Figure 2 and Figure 5The sliding structure 5 shown is two, two sliding structures 5 are symmetrically arranged on both sides of the second air outlet 22 along the third direction Z, so that the connection reliability between the inner shell 2 and the outer shell 1 can be enhanced; but the setting position of the sliding structure 5 of the present application is not limited to Figure 17 and Figure 18 The position shown, the number of sliding structures 5 can be one, or multiple, such as in some embodiments, along the second direction Y, the sliding structure 5 can be located at a position opposite the second air outlet 22.

[0101] Figure 1 The structure shown is a structure schematic diagram of a display device provided by an embodiment of the present application, Figure 2 The explosion structure shown is a structure schematic diagram of a display device provided by an embodiment of the present application; based on the same inventive concept, the present application also provides a display device, comprising a display panel 200 and a heat dissipation assembly 100 as described above; along the second direction Y, the display panel 200 is located on one side of the first air outlet 13; the heat dissipation assembly 100 is used to dissipate heat for the display panel 200.

[0102] Please refer to Figure 7 , Figure 14 , Figure 17 , Figure 18 , Figure 7 and Figure 17 , the display device of the present application adopts the heat dissipation assembly 100, the display panel 200 is located on one side of the first air outlet 13, the respective constituent structures of the heat dissipation assembly 100 and the display panel 200 are not dependent on each other, the independence of the heat dissipation assembly 100 and the display panel 200 in structure is good, and the reliability is high. In addition, the inner shell 2 of the heat dissipation assembly of the present application can be located in the outer shell 1, so that the display device of the present application also has the characteristics of small volume and easy to carry; in addition, since the heat dissipation assembly 100 of the present application has the characteristics of adjustable air outlet width, air outlet wind power and wind direction, therefore, the display panel 200 of the present application can be ensured to be in a normal working temperature range, therefore, the display device of the present application has the characteristics of good working performance reliability. Finally, the display device of the present application has other beneficial effects of the heat dissipation assembly 100 provided by the embodiments of the present application, and the specific description of the heat dissipation assembly 100 can be referred to the specific description of the heat dissipation assembly 100 of each embodiment above, which will not be repeated here.

[0103] Please continue to refer to Figure 18 and Figure 7 and Figure 17 In some optional embodiments of the present application, the display device comprises a first working mode, in the first working mode, at least one side of the display panel 200 extends along the first direction X.

[0104] Specifically, please continue to refer to Figure 18 and Figure 7 andFigure 17 The display device of the present application comprises a first working mode, in which at least one side edge of the display panel 200 extends along the first direction X, and the first air outlet 13 and the second air outlet 22 of the heat dissipation assembly 100 also extend along the first direction X. In this way, the heat dissipation assembly 100 can better dissipate heat for the display panel 200 in the display device of the present application.

[0105] Further, generally, the display panel comprises a driving chip, which generates the largest amount of heat. Therefore, in some embodiments of the present application, the driving chip is arranged at the lower part of the display panel 200 along the second direction Y, and the lower part of the display panel 200 is close to the heat dissipation assembly 100 when the display panel 200 is combined with the heat dissipation assembly 100, so that the heat dissipation at the driving chip is more convenient.

[0106] In some optional embodiments of the present application, the deflection of the first air outlet adjusting structure 31 and the second air outlet adjusting structure 32 can be adjusted according to the temperature of the area close to the heat dissipation assembly 100 and the area away from the heat dissipation assembly 100 along the second direction Y of the display panel 200, so as to change the direction of the air outlet, so that the heat dissipation assembly 100 can effectively dissipate heat in the high-temperature area and ensure the normal operation of the display 200. For example, when the temperature above the display panel (i.e., the area away from the heat dissipation assembly 100) is higher than a set value, the driving assembly drives the first air outlet adjusting structure 31 and / or the second air outlet adjusting structure 32 to turn inward together, and the air speed and stroke of the heat dissipation assembly 100 are higher, so as to dissipate heat in the area above the display panel. When the temperature above the display panel 200 is lower than the set value, the driving assembly drives the first air outlet adjusting structure 31 and / or the second air outlet adjusting structure 32 to turn outward together, and at this time, the display assembly 100 mainly dissipates heat for the lower driving chip.

[0107] Please refer to Figure 18 , Figure 1 and Figure 2 In some optional embodiments of the present application, the display panel 200 is a flexible display panel, and the display panel 200 comprises a winding and unwinding state. Along the first direction X, the flexible display panel comprises a fixed end 01 and a moving end 02, the fixed end 01 is fixedly connected with the outer shell 1, and the moving end 02 can move along the first direction X relative to the fixed end 01 to unwind the flexible display panel. The moving end 02 is provided with a first magnet 021. Along the first direction X, the inner shell 2 is provided with a second magnet 022 at the end opposite to the first air inlet 13. The second magnet 022 is located on the moving path of the first magnet 021.

[0108] Specifically, when the display panel 200 is a flexible display panel, the display panel 200 includes a winding and an unwinding state. At this time, the overlap width of the first air outlet 13 and the second air outlet 22 can be adjusted according to the unfolded width of the display panel 200 in the first direction, so that the width of the air outlet of the heat dissipation component 100 matches the area of ​​the flexible display panel that needs heat dissipation. Specifically, the present invention provides a first magnet 021 on the moving end 02; a second magnet 022 is provided at the end of the inner shell 2 opposite to the first air inlet 13 along the first direction X; the second magnet 022 is located on the moving path of the first magnet 021. Thus, please refer to... Figure 17 , Figure 18 , Figure 17 and Figure 18 In some optional embodiments of the present invention, along the first direction X, as the flexible display panel unfolds, when the first magnet 021 of the moving end 02 of the flexible display panel meets the second magnet 022 of the inner shell 1, the first magnet 021 and the second magnet 022 generate magnetic attraction. As the flexible display panel further unfolds, the inner shell 2 also moves toward the outer shell 1. At this time, the overlap width of the first air outlet 13 and the second air outlet 22 in the first direction X gradually narrows, and the width of the outlet air of the heat dissipation component 100 is adapted to the unfolded width of the flexible display panel 200. In this way, the heat dissipation component 100 can meet the heat dissipation requirements of flexible display panels with different unfolded widths.

[0109] In the display device of the present invention, the width of the outlet air of the heat dissipation component 100 is adapted to the unfolded width of the flexible display panel 200, so that the heat dissipation component 100 can meet the heat dissipation requirements of flexible display panels with different unfolded widths. In addition, the present invention achieves the adaptation of the outlet air width of the heat dissipation component 100 to the unfolded width of the flexible display panel 200 through the cooperation of the first magnet 021 and the second magnet 022, which has the characteristics of simple and ingenious structure.

[0110] Furthermore, it should be noted that the display panel 200 of the display device of the present invention can be a non-flexible display panel or a flexible display panel. When the display panel is a non-flexible display panel, the overlap width of the first air outlet 13 and the second air outlet 22 can be adjusted according to the size of the display panel 200 in the first direction so that the air outlet width of the heat dissipation component 100 matches the area of ​​the non-flexible display panel that needs to be dissipated, so as to meet the normal operating temperature range of the display device.

[0111] Please continue to refer to this. Figure 17 and Figure 18 In some optional embodiments of the present invention, an adsorption type fixing seat 14 is provided on the shell wall of the heat dissipation component 100, and the display panel 200 is fixedly connected to the heat dissipation component 100 through the adsorption type fixing seat 14.

[0112] Specifically, please continue to refer to Figure 1 and Figure 3 , the display panel 200 is fixedly connected with the heat dissipation assembly 100 through the adsorbing fixing seat 14, which can bring the following advantages:

[0113] Firstly, when the display panel 200 needs to be cooled, the display panel 200 can be detachably connected at the first air outlet 13 and / or the second air outlet 22 of the heat dissipation assembly 100, and the display panel 200 is cooled by the heat dissipation assembly 100; when the display panel 200 does not need to be cooled, the display panel 200 can also be removed; the heat dissipation assembly 100 can be used to cool other display panels 200 that need to be cooled.

[0114] Secondly, when the display device is assembled, the display panel 200 is only needed to be installed at the air outlet of the heat dissipation assembly by magnetic attraction or other means, and can be operated by hand, so that quick assembly can be realized.

[0115] Thirdly, the display panel 200 does not need to be cooled at all times during work, and when the heat of the display panel 200 accumulates to a certain degree, the display panel 200 can be cooled by the heat dissipation assembly 100, and when the temperature of the display panel reaches the qualified temperature, the display panel does not need to be cooled; at this time, the heat dissipation assembly 100 can be used to cool other display panels 200 that need to be cooled, so that one heat dissipation assembly 100 can meet the cooling needs of multiple display panels.

[0116] In an exhibition, the display device needs to be used for a long time to display products, and for some display devices with large screen size and long working time, the phenomenon of heating is easy to occur, so timely cooling is needed; the display device with the heat dissipation assembly is more suitable for such occasions, which not only has the advantage of convenient carrying, but also is easy to assemble and can be quickly used.

[0117] It should be further pointed out that please combine Figure 17 , Figure 18 , Figure 3 and Figure 9 , in some embodiments of the present application, the display panel includes a fixed end 01 which does not have a display function and mainly serves a fixing and mounting function and does not need to be cooled; therefore, in order to effectively utilize the wind force, the first air outlet 13 at the outer shell 1 is arranged away from the fixed end 01, so that along the first direction X, the first air outlet 13 is reserved a distance H1 from one end of the first air inlet 11 of the outer shell 1; please refer to Figure 17 , since the fixed end 01 does not need to be cooled, one end of the inner shell 2 is also apart from the first air inlet 11 along the first direction X by h1, and the value of h1 is approximately equal to H1. In addition, as Figure 18As shown, the position between one end of the inner housing 2 and the first air inlet 11 can be used to set the driving assembly.

[0118] In addition, please continue to refer to ​ and ​ , along the second direction Y, the first air outlet 13 is located at the top of the outer housing 1, and the shell wall opposite to the first air outlet 13 is the bottom of the outer housing 1, and the outer surface of the bottom is a plane. The bottom of the outer housing 1 is a plane, and the heat dissipation assembly 100 can be placed horizontally on the ground without other auxiliary supports or devices, and has the characteristics of good stability.

[0119] In summary, the display panel and display device provided by the present application at least achieve the following beneficial effects:

[0120] The heat dissipation assembly 100 of the present application can adjust the overlapping width of the first air outlet 13 and the second air outlet 22 along the first direction X according to the required heat dissipation width of the object to be cooled, so that the air outlet width of the heat dissipation assembly 100 is suitable for the required heat dissipation width of the object to be cooled. In this way, on the one hand, the air outlet of the heat dissipation assembly 100 can be more effectively applied, avoiding the phenomenon of cold air waste caused by the air outlet width of the heat dissipation assembly 100 being larger than the required heat dissipation width of the object to be cooled, so as to improve the cold air utilization rate of the heat dissipation device; on the other hand, the heat dissipation assembly 100 of the present application includes an inner housing 1 and an outer housing 2, and the inner housing 1 can be located in the outer housing 2. In this way, under the condition that the heat dissipation assembly 100 is not working, or in the case that the required heat dissipation width of the object to be cooled is small, the space occupied by the heat dissipation assembly 100 is small, which is suitable for carrying or placing; thirdly, the structure of the heat dissipation assembly 100 of the present application is independent, and can not depend on the object to be cooled, which is a relatively independent assembly, so it is convenient to assemble or maintain.

[0121] The display device of the present application adopts the heat dissipation assembly 100, and the display panel 200 is located on one side of the first air outlet 13. The respective constituent structures of the heat dissipation assembly 100 and the display panel 200 are independent of each other, and the heat dissipation assembly 100 and the display panel 200 have good structural independence and high reliability. In addition, the inner housing 2 of the heat dissipation assembly of the present application can be located in the outer housing 1, so that the display device of the present application also has the characteristics of small size and easy to carry. In addition, since the heat dissipation assembly 100 of the present application has the characteristics of adjustable air outlet width, air outlet air power and air direction, the display panel 200 of the present application can be ensured to be in a normal working temperature range, and therefore the display device of the present application has the characteristics of good working performance and reliability.
