[0021] The following disclosure provides many different embodiments or examples for implementing the different features of the provided subject matter. Specific examples of components and arrangements are described herein. Of course, these are only examples and are not intended to be limiting. The disclosure may repeat element symbols and / or letters in various examples. This repetition is for simplicity and clarity purposes and does not itself indicate the relationship between the various embodiments and / or configurations discussed.

[0022] The following is a detailed discussion of embodiments of the present disclosure. However, it should be appreciated that the present disclosure provides many applicable inventive concepts that can be embodied in a variety of specific contexts. The specific embodiments discussed are merely illustrative and do not limit the scope of the present disclosure.

[0023] Figure 1 is a perspective view of a display box 1 according to an embodiment of the present disclosure. Figure 2 is an exploded view of a display box 1 according to an embodiment of the present disclosure.

[0024] In some embodiments, the display box 1 may include a central portion 10, transparent covers 11, 12, a heat exchanger 13 (in Figure 2 ), the internal flow generator 14 (in Figure 2 ) and the external flow generator 15 (in Figure 2 (marked in).

[0025] The central portion 10 may have an inlet 10i and an outlet 10u opposite the inlet 10i. The central portion 10 may have a side 101 and a side 102 opposite the side 101. The central portion 10 may be configured to accommodate a heat exchanger 13. An internal flow generator 14 and an external flow generator 15 may be disposed adjacent to the central portion 10 and the heat exchanger 13.

[0026] The transparent cover 11 may be disposed on the side 101 of the central portion 10. The transparent cover 11 may be pivotally connected to the central portion 10 by one or more pivot joints (e.g., Figure 3The transparent cover 11 is rotatably connected to the central part 10 by a pivot joint 11p in the middle. The transparent cover 11 can be closed (e.g., at a first position) or opened (e.g., at a second position) relative to the central part 10 by one or more pivot joints.

[0027] The transparent cover 11 may be provided with one or more sealing components (e.g. Figure 3 The sealing assembly 11r in the transparent cover 11 is removably attached to the central portion 10. In some embodiments, the sealing assembly may include a rubber gasket or an O-ring. In some embodiments, the sealing assembly may be disposed between the transparent cover 11 and the central portion 10. In some embodiments, the sealing assembly may be arranged at the periphery of the transparent cover 11.

[0028] The transparent cover 11 and the central portion 10 may define a space on the side 101. The display module 21 may be disposed in the space on the side 101. In some embodiments, as in Figure 1 As shown in , when the transparent cover 11 is opened (eg, at the second position), the display module 21 may be exposed to the external environment (eg, air) or to the outside of the display box 1 .

[0029] In some embodiments, such as in Figure 3 , when the transparent cover 11 is closed (e.g., at the first position), the transparent cover 11 can be attached to the central portion 10 by a sealing component 11r. The transparent cover 11 and the sealing component 11r can isolate the space on the side 101 from the external environment (e.g., air). For example, the transparent cover 11, the central portion 10, and the sealing component 11r can define an airtight space for the display module 21.

[0030] The transparent cover 12 may be disposed on the side 102 of the central portion 10. The transparent cover 12 may be pivotally attached to the central portion 10 via one or more pivot joints (e.g., Figure 3 The transparent cover 12 is rotatably connected to the central part 10 by a pivot joint 12p in the middle. The transparent cover 12 can be closed (e.g., at a first position) or opened (e.g., at a second position) relative to the central part 10 by one or more pivot joints.

[0031] The transparent cover 12 may be provided by one or more sealing components (e.g., Figure 3 The sealing assembly 12r) in the transparent cover 12 is removably attached to the central portion 10. In some embodiments, the sealing assembly may include a rubber gasket or an O-ring. In some embodiments, the sealing assembly may be disposed between the transparent cover 12 and the central portion 10. In some embodiments, the sealing assembly may be arranged at the periphery of the transparent cover 12.

[0032] The transparent cover 12 and the central portion 10 may define a space on the side 102. The display module 22 (at Figure 2) can be placed in the space on the side 102. In some embodiments, such as in Figure 1 As shown in FIG. 1 , when the transparent cover 12 is opened (eg, at the second position), the display module 22 (at Figure 2 The display module 22 may be exposed to the external environment (eg, air) or to the outside of the display box 1. In some embodiments, the display module 22 is detachable. {0><}0{> Once the display module 22 housed in the display box fails or is damaged, the display box can be used again.

[0033] In some embodiments, such as in Figure 3 , when the transparent cover 12 is closed (e.g., at a first position), the transparent cover 12 can be attached to the central portion 10 by a sealing component 12r. The transparent cover 12 and the sealing component 12r can isolate the space on the side 102 from the external environment (e.g., air). For example, the transparent cover 12, the central portion 10, and the sealing component 12r can define an airtight space for the display module 22.

[0034] The display box 1 , the display module 21 and the display module 22 may be collectively referred to as a double-sided display.

[0035] Although the display box 1 is illustrated as being used in combination with the display module 21 and the display module 22, the present invention is not limited thereto. The display box 1 may be a general display box used in combination with other devices, other displays, or other panels.

[0036] The heat exchanger 13 may be disposed in the central portion 10. In some embodiments, the heat exchanger 13 may be integrated in the central portion 10. In some embodiments, the heat exchanger 13 may be defined by the central portion 10. In some embodiments, the heat exchanger 13 may be a part of the central portion 10. The heat exchanger 13 may include channels for an internal heat exchange circuit and channels for an external heat dissipation path (relative to the Figure 3 further described).

[0037] The internal flow generator 14 may be disposed adjacent to the inlet 10i of the central portion 10. In some embodiments, the internal flow generator 14 may include a fan. In some embodiments, the internal flow generator 14 may be configured to generate an internal air flow through the internal heat exchange circuit.

[0038] The external flow generator 15 may be disposed adjacent to the outlet 10u of the central portion 10. In some embodiments, the external flow generator 15 may include a fan. In some embodiments, the external flow generator 15 may be configured to generate an external air flow or an ambient air flow through the external heat dissipation path.

[0039] Figure 3 is a cross-sectional view of a display box 1 according to an embodiment of the present disclosure.

[0040] In some embodiments, heat exchanger 13 may include an aluminum extrusion (e.g., a t-slot aluminum extrusion). In some embodiments, heat exchanger 13 may include a plurality of channels or units. For example, central portion 10 may include or define channel C1, channel C2, channel C3, and channel C4. In some embodiments, channel C1, channel C3, channel C4, and channel C2 may be stacked one above the other in sequence. In some embodiments, heat exchanger 13 may be integrally formed or formed as a single piece.

[0041] Channel C1 of heat exchanger 13 may be fluidly conductive to a space defined by transparent cover 11, central portion 10, and sealing assembly 11r for accommodating display module 21. Channel C1 may be adjacent to and thermally connected to display module 21. Channel C1 may define a portion of internal heat exchange loop C1i.

[0042] Channel C2 of heat exchanger 13 may be fluidly conductive to a space defined by transparent cover 12, central portion 10, and sealing assembly 12r for accommodating display module 22. Channel C2 may be adjacent to and thermally connected to display module 22. Channel C2 may define a portion of an internal heat exchange loop C2i.

[0043] The internal heat exchange circuit C2i can be fluidly conductive to the internal heat exchange circuit C1i (relative to Figure 6 Further described). Therefore, the space defined by the transparent cover 11, the central portion 10 and the sealing component 11r for accommodating the display module 21 can be fluidly conducted to the space defined by the transparent cover 12, the central portion 10 and the sealing component 12r for accommodating the display module 22.

[0044] The channels C3 and C4 of the heat exchanger 13 may be fluidly conducted to the external environment through the inlet 10i and the outlet 10u. For example, an external air flow may enter the channels C3 and C4 through the inlet 10i and exit the channels C3 and C4 through the outlet 10u. The channel C3 may define an external heat dissipation path C3e. The channel C4 may define an external heat dissipation path C4e. The external flow generator 15 may be disposed adjacent to the channels C3 and C4 and configured to generate an external air flow through the external heat dissipation paths C3e and C4e.

[0045] Channel C3 may be adjacent to and thermally connected to channel C1. In some embodiments, an external heat dissipation path C3e defined by channel C3 may be configured to dissipate heat from an internal heat exchange loop C1i defined by channel C1. In some embodiments, a flow direction of channel C1 may be opposite to a flow direction of channel C3.

[0046] Channel C4 may be adjacent to and thermally connected to channel C2. In some embodiments, an external heat dissipation path C4e defined by channel C4 may be configured to dissipate heat from an internal heat exchange loop C2i defined by channel C2. In some embodiments, the flow direction of channel C2 may be opposite to the flow direction of channel C4.

[0047] In some embodiments, the display module 21 may be supported or carried on the heat exchanger 13 by one or more carriers (or supporting elements) 21s. For example, the carrier 21s may provide mechanical support for the display module 21. For example, the carrier 21s may directly contact the display module 21 (e.g., the backlight layer 21c of the display module 21) and directly contact the heat exchanger 13. For example, the display module 21 may have a front side configured to emit light and a rear side directly contacting the carrier 21s.

[0048] In some embodiments, the display module 21 may include a display panel 21a, an optical film 21b, and a backlight layer 21c. The display panel 21a may be disposed between the optical film 21b and the transparent cover 11. The optical film 21b may be disposed between the display panel 21a and the backlight layer 21c. The backlight layer 21c may be disposed between the optical film 21b and the carrier 21s.

[0049] For example, the display panel 21a may include a glass panel, a liquid crystal panel, a plastic panel or other types of panels. For example, the optical film 21b may include a diffuser, a reflector, a polarizer, a filter, a light guide element, a lens or other optical elements. The backlight layer 21c may include a plurality of light-emitting pixels.

[0050] In some embodiments, the internal flow generator 14 may be disposed adjacent to the carrier 21s. In some embodiments, the internal flow generator 14 may be disposed adjacent to the channel C1 of the heat exchanger 13. In some embodiments, the internal flow generator 14 may be configured to generate an internal air flow through the internal heat exchange circuit C1i. For example, the internal flow generator 14 may be fluidly conducted to the channel C1. The internal flow generator 14 may be configured to discharge air from the channel C1 into a space defined by the transparent cover 11, the central portion 10, and the sealing component 11r for accommodating the display module 21.

[0051] In some embodiments, the internal air flow generated by the internal flow generator 14 may flow between the transparent cover 11 and the display panel 21a, and between the display panel 21a and the optical film 21b. Then, the internal air flow may flow into the channel C1 through the opening (or hole) C1h on the side wall of the channel C1.

[0052] In some embodiments, the internal heat exchange circuit C1i can be isolated from the external environment. For example, the external air flow cannot enter the internal heat exchange circuit C1i. For example, the internal heat exchange circuit C1i can be isolated from the external heat dissipation path C3e by a baffle C1b. The baffle C1b can be part of the heat exchanger 13 or can be connected to the heat exchanger 13. The baffle C1b can extend from the side wall of the channel C1.

[0053] In some embodiments, the display module 22 may be supported or carried on the heat exchanger 13 by one or more carriers (or support elements) 22s. For example, the carrier 22s may provide mechanical support for the display module 22. For example, the carrier 22s may directly contact the display module 22 (e.g., the backlight layer 22c of the display module 22) and directly contact the heat exchanger 13. For example, the display module 22 may have a front side configured to emit light and a rear side directly contacting the carrier 22s.

[0054] In some embodiments, similar to the display module 21 , the display module 22 may include a display panel 22 a , an optical film 22 b , and a backlight layer 22 c .

[0055] In some embodiments, the internal flow generator 14 may be disposed adjacent to the carrier 22s. In some embodiments, the internal flow generator 14 may be disposed adjacent to the channel C2 of the heat exchanger 13. In some embodiments, the internal flow generator 14 may be configured to generate an internal air flow through the internal heat exchange loop C2i. For example, the internal flow generator 14 may be fluidly conducted to the channel C2. The internal flow generator 14 may be configured to discharge air from the channel C2 into a space defined by the transparent cover 12, the central portion 10, and the sealing component 12r for accommodating the display module 22.

[0056] In some embodiments, the internal air flow generated by the internal flow generator 14 may flow between the transparent cover 12 and the display panel 22a, and between the display panel 22a and the optical film 22b. Then, the internal air flow may flow into the channel C2 through the opening (or hole) C2h on the side wall of the channel C2.

[0057] In some embodiments, the internal heat exchange circuit C2i can be isolated from the external environment. For example, the external air flow cannot enter the internal heat exchange circuit C2i. For example, the internal heat exchange circuit C2i can be isolated from the external heat dissipation path C4e by a baffle C2b. The baffle C2b can be part of the heat exchanger 13 or can be connected to the heat exchanger 13. The baffle C2b can extend from the side wall of the channel C2.

[0058] Figure 4 According to the embodiment of the present disclosure Figure 3 A cross-sectional view of a portion of the display box 1 in FIG.

[0059] The external heat dissipation path C3e defined by the channel C3 can be isolated from the space on the side 101 (and from the channel C1) by the baffle C1b. The baffle C1b can extend from the side wall of the channel C3 (or the side wall of the channel C1) to a portion of the transparent cover 11.

[0060] When the transparent cover 11 is closed or not closed, the external heat dissipation path C3 e defined by the channel C3 may be isolated from the space on the side surface 101 by the baffle C1 b.

[0061] The internal air flow of the internal heat exchange circuit C1i can flow into the channel C1 through the opening C1h on the side wall of the channel C1.

[0062] The external heat dissipation path C4e defined by the channel C4 can be isolated from the space on the side 102 (and from the channel C2) by the baffle C2b. The baffle C2b can extend from the side wall of the channel C4 (or the side wall of the channel C2) to a portion of the transparent cover 12.

[0063] When the transparent cover 12 is closed or not closed, the external heat dissipation path C4 e defined by the channel C4 can be isolated from the space on the side surface 102 by the baffle C2 b.

[0064] The internal air flow of the internal heat exchange circuit C2i can flow into the channel C2 through the openings C2h on the side walls of the channel C2.

[0065] Figure 5 According to the embodiment of the present disclosure Figure 3 A cross-sectional view of a portion of the display box 1 in FIG.

[0066] The internal flow generator 14 (on the left side) may be disposed adjacent to the channel C1 and may be fluidly conductive to the channel C1. The internal flow generator 14 may be configured to exhaust air from the channel C1 and generate an internal air flow of the internal heat exchange loop C1i that flows between the transparent cover 11 and the display panel 21a and between the display panel 21a and the optical film 21b.

[0067] The internal flow generator 14 (on the right side) may be disposed adjacent to the channel C2 and may be fluidly conductive to the channel C2. The internal flow generator 14 may be configured to exhaust air from the channel C2 and generate an internal air flow of the internal heat exchange loop C2i that flows between the transparent cover 12 and the display panel 22a and between the display panel 22a and the optical film 22b.

[0068] Figure 6 is a perspective view of a portion of a display box 1 according to an embodiment of the present disclosure. Figure 6The transparent cover 11, the internal flow generator 14, the external flow generator 15 and the display module 22 are not shown.

[0069] The width w1 of the transparent cover 12 (and the transparent cover 11) of the display box 1 may be greater than the width w2 of the display module 21 (and the display module 22). When the transparent covers 11 and 12 are closed, the transparent covers 11 and 12 may define an airtight space for the display modules 21 and 22. On at least one side of the display box 1, the internal heat exchange circuit C1i may be fluidly conducted to the internal heat exchange circuit C2i. For example, the internal heat exchange circuit C1i and the internal heat exchange circuit C2i may be fluidly conducted through a path P that passes through channels C1, C2, C3, and C4.

[0070] According to some embodiments of the present disclosure, since the channels C1, C2, C3, and C4 of the heat exchanger 13 are integrated in the central portion 10, the size of the display cabinet 1 is reduced. In addition, by isolating the external heat dissipation path C3e and the external heat dissipation path C4e from the internal heat exchange circuit C1i and the internal heat exchange circuit C2i, the waterproofness of the display cabinet 1 is improved. In addition, since the internal heat exchange circuit C1i and the internal heat exchange circuit C2i are fluidly conducted, the temperature on the sides 101 and 102 of the central portion 10 can be balanced. The heat dissipation efficiency can be improved.

[0071] Fig. 7A , 7B 7C, 7D, 7E, 7F and 7G are cross-sectional views of a portion of a display box according to an embodiment of the present disclosure. In some embodiments, the heat exchanger 13 of the display box 1 may have a Fig. 7A , 7B , 7C, 7D, 7E, 7F and 7G.

[0072] refer to Fig. 7A , the heat exchanger 13 may have four groups, and each group has channels C1, channels C3, channels C4, and channels C2 stacked one above the other in sequence. In some embodiments, the heat exchanger 13 may include but is not limited to one, two, three, four, or more groups.

Channel C3 defines an external heat dissipation path shared by channels C1 and C2.

[0074] refer to Figure 7C , Figure 7C The heat exchanger 13 in is similar to Figure 7B The heat exchanger 13 in the embodiment of the present invention is different in that Figure 7C The heat exchanger 13 in FIG. 1 has an interconnecting channel C5 extending between the sides 101 and 102. The interconnecting channel C5 may pass through the channel C1, the channel C3, and the channel C2. The channel C1 and the channel C2 may be fluidically conducted (or thermally conducted) through the interconnecting channel C5, as indicated by the arrows. For example, one or more openings may be formed between the channel C1 and the interconnecting channel C5, and one or more openings may be formed between the channel C2 and the interconnecting channel C5. The channel C1 and the channel C2 may be fluidically conducted through the interconnecting channel C5 by heat convection. Alternatively, the channel C1 and the channel C2 may be thermally conducted through the interconnecting channel C5 by heat conduction. Thus, in addition to fluid conduction on at least one side of the display box (such as on the Figure 6 In addition to the above (as shown in FIG. 1 ), the display box may further have fluid conduction (or heat conduction) on its central portion to facilitate temperature balancing.

[0075] refer to Fig.7D , Fig.7D The heat exchanger 13 in is similar to Figure 7C , the difference is that channel C3 can be surrounded by channel C1 and channel C2 and channel C1 and channel C2 can be fluidly conductive (or thermally conductive) without interconnecting channel C5, as indicated by the arrows. For example, one or more openings can be formed between channel C1 and channel C2. Channel C1 and channel C2 can be fluidly conductive by thermal convection. Alternatively, channel C1 and channel C2 can be thermally conductive by thermal conduction.

[0076] refer to Fig. 7E , Fig. 7E The heat exchanger 13 in is similar to Fig.7D The heat exchanger 13 in FIG. 1 is different in that the channel C1 and the channel C2 are formed together as a single piece. For example, the channel C1 and the channel C2 may be a combination of the channels on the sides 101 and 102.
