[0031] The display device includes a variety of, television is a representative display device, the display device of this kind of television is a kind of electronic product with thin as beauty, the thinner the television, the smaller the internal space, mainboard power supply and other internal devices will be very thin, the fin thin will lead to the heat dissipation rate reduces, space thin will affect gas flow, also can affect heat dissipation;And high-power power supply and high-level chip in display device high operation, can generate greater heat, due to the demand of ultra-thin body is not convenient for the installation of fan, therefore in this kind of display device represented by ultra-thin television, it is difficult to effectively cool the mainboard.

[0032] The utility model provides a kind of display device.

[0033] Please refer to Figure 1 And Figure 2 In the embodiment of the utility model, the display device 100 includes: mainboard 1, speaker box 2, gas guide pipe 3 and at least one check valve 4;Speaker box 2 has inner cavity and gas guide hole 21, the inner cavity is communicated with the outside of the speaker box 2 by the gas guide hole 21;Gas guide pipe 3 has air inlet 31, air outlet 32 and connecting port 33, which are communicated with each other, the gas guide pipe 3 is arranged between the mainboard 1 and the speaker box 2, the connecting port 33 is communicated with the gas guide hole 21, and the air outlet 32 is arranged towards the mainboard 1;At least one check valve 4, the check valve 4 is installed on the air outlet 32, for making gas from the gas guide hole 21 to the outside of the exhaust port one-way conduction.

[0034] In the design of the sound box 2, the air guide hole 21 (also known as a guide hole, a phase inversion hole or a gas discharge hole) is provided in the structure mainly to optimize the propagation of low-frequency sound and improve the sound quality performance. Gas flows in or out at the position of the air guide hole 21. The technical scheme of the utility model cools the main board 1 by using the gas flowing out of the air guide hole 21. Specifically, in order to make the gas blown out of the air guide hole 21 blow towards the main board 1 and have a relatively fast flow rate to cool the main board 1, a gas guide pipe 3 is provided. The gas guide pipe 3 has a connecting port 33 and an air outlet 32. The gas blown out of the air guide hole 21 enters the gas guide pipe 3 through the connecting port 33 and is blown out of the air outlet 32 of the gas guide pipe 3. The air outlet 32 of the gas guide pipe 3 is arranged towards the main board 1 so that the gas flowing out is blown out towards the main board 1 to cool the main board 1. The gas guide pipe 3 is arranged so that the cross-sectional area of the flow channel of the gas flow is relatively small, so that the pressure in the gas guide pipe 3 is relatively high and the flow rate is relatively fast, and the effect of air cooling is relatively good. Since the position of the air guide hole 21 of the sound box 2 not only has gas flowing out but also has gas flowing in, when gas flows towards the inner cavity of the sound box 2, the gas blown out to cool the main board 1 (which has been heated by the main board 1 and has a relatively high temperature at this time) will be sucked back into the sound box 2. When the gas is blown out of the air guide hole 21 again to cool the main board 1, the temperature of the blown-out gas is relatively high, and the cooling effect on the main board 1 is not good. In order to prevent the gas cooled by the main board 1 from being sucked back into the sound box 2 again, a one-way valve 4 is arranged at the position of the air outlet 32 so that the gas can only be blown out of the air outlet 32 and avoid entering the gas guide pipe 3 from the air outlet 32 to prevent hot air from flowing in and out repeatedly. Since the gas can only flow in one direction at the position of the air outlet 32, in order to make the gas flow back to the inner cavity normally and ensure the sound quality of the sound box 2, an air inlet 31 is arranged on one side of the gas guide pipe 3. The air inlet 31 is not arranged towards the main board 1 so that the temperature of the sucked-in gas is relatively low. The gas with a relatively low temperature is sucked in from the air inlet 31 and blown out from the air outlet 32.

[0035] When the gas is blown out of the air guide hole 21, since the gas guide pipe 3 also has the air inlet 31, when the gas is blown towards the main board 1, the gas will also be blown out of the air inlet 31, thus reducing the flow rate and flow volume of the gas blown out of the air outlet 32 and weakening the heat dissipation effect on the main board 1. Therefore, the one-way valve 4 is provided with two one-way valves. One of the one-way valves 4 is installed at the air outlet 32, and the other one-way valve 4 is installed at the air inlet 31. The one-way valve 4 installed at the air inlet 31 is used to make the gas flow from the outside of the air inlet 31 to the air guide hole 21 in one direction. Therefore, when the air guide hole 21 sucks in air, the gas outside the gas guide pipe 3 flows from the air inlet 31 to the connecting port 33; when the air guide hole 21 blows air, the gas outside the gas guide pipe 3 flows from the connecting port 33 to the air outlet.

[0036] Since the hot air is upwardly floating, blowing air from the position below the main plate 1 to the main plate 1 is more conducive to making the hot air (due to the heat exchange between the gas and the main plate 1, and the heat exchange between the main plate 1 and the surrounding gas) away from the main plate 1, thereby reducing the temperature around the main plate 1. Therefore, the main plate 1 is located at the position above the sound box 2, the upper end of the air duct 3 is provided with the air outlet 32, the lower end of the air duct 3 is provided with the connecting port 33, and the side wall of the air duct 3 is provided with the air inlet 31.

[0037] In order to reduce the temperature of the main plate 1, the main plate 1 has a plurality of heat dissipation fins 12, the main plate 1 has a plate body 11 and a plurality of heat dissipation fins 12, the plurality of heat dissipation fins 12 are arranged in the left-right direction and are arranged in the up-down direction, the plurality of heat dissipation fins 12 are arranged in the left-right direction and are arranged in the up-down direction, and the plurality of heat dissipation fins 12 are arranged in the left-right direction and are arranged in the up-down direction. The air outlet 32 is arranged towards the lower end of the plurality of heat dissipation fins 12, so that the air blown out of the air outlet 32 is blown along the extension direction of the heat dissipation channel to each heat dissipation channel, thereby taking away the heat of the heat dissipation fins 12 on both sides of the heat dissipation channel, and further cooling the plate body 11, thereby achieving the cooling of the whole main plate 1.

[0038] For the specific setting mode of the one-way valve 4, please refer to Figure 5 In one embodiment, the one-way valve 4 includes a main body 41 and at least one protruding portion 42, the at least one protruding portion 42 is arranged on one side of the main body 41, and the protruding portion 42 is elastically arranged; wherein the air passage of the one-way valve 4 is arranged from the free end of the protruding portion 42 to the other side of the main body 41, so as to form an air outlet port 421 at the free end of the protruding portion 42 and an air inlet port 411 at the other side of the main body 41, and the protruding portion 42 is tapered in the direction from the air inlet port 411 to the air outlet port 421. Take the one-way valve 4 installed in the air outlet 32 as an example: in the direction from the other side of the main body 41 to the free end, the part of the air passage located in the protruding portion 42 is tapered, and the part of the air passage located in the main body 41 is uniform. When blowing air towards the main plate 1, the gas expands the air passage from the inside and is blown out of the air outlet 32, and when inhaling, the gas pressure further presses the side wall of the air passage due to the inclined surface on the outside of the protruding portion 42 and the larger pressure, so that the opposite side wall of the air passage abuts, thereby closing the air passage and preventing the gas from passing through the air passage, thereby achieving the effect of one-way conduction. The at least one protruding portion 42 of the one-way valve 4 is elastically arranged, which can be made of rubber, silicone or other materials.

[0039] Since the sound box 2 and the main plate 1 are standard products, it is inconvenient to integrally arrange the air duct 3 with one of the sound box 2 or the main plate 1, and for the main plate 1 with low heat production, it is not necessary to dissipate heat by the sound box 2, so the air duct 3 can be detachably arranged between the main plate 1 and the sound box 2. According to the condition of the main plate 1, the air duct 3 is selectively arranged.

[0040] The specific connection mode can refer to Figure 3 and Figure 4 One end of the air duct 3 provided with the connecting port 33 is fixedly connected with the sound box 2 through a screwing element. The position of the air duct 3 is determined. Since the sound box 2 vibrates and the other side of the air duct 3 is a cantilever, the air duct 3 is prevented from swinging and interfering or colliding with other mounting components, so the display device 100 further comprises a plug-in element 5 fixedly arranged on the outer circumferential side of the air duct 3, and the plug-in element 5 is plugged in the main plate body 11 in the up-down direction. In order to facilitate plugging, one side of the main plate body 11 towards the plug-in element 5 is provided with a first plug-in groove 111, and the plug-in element 5 is provided with a second plug-in groove 51 corresponding to the first plug-in groove 111, and the openings of the first plug-in groove 111 and the second plug-in groove 51 are both expanded to facilitate the corresponding plugging of the first plug-in groove 111 and the second plug-in groove 51. The two plug-in grooves are plugged in each other relative to the plugging of one plug-in groove and the plate body, and the connection effect is more firm.

[0041] In order to facilitate the mounting of the one-way valve 4 and to replace the one-way valve 4 when the elastic part (rubber material has aging problem) of the one-way valve 4 ages and the elastic effect is weakened, the air duct 3 comprises a first pipe body 3a and a second pipe body 3b, the first pipe body 3a and the second pipe body 3b are detachably connected, and the first pipe body 3a and the second pipe body 3b jointly form the air inlet 31, the air outlet 32 and the connecting port 33. When the first pipe body 3a and the second pipe body 3b are detached, the one-way valve 4 can be taken out, and when the first pipe body 3a and the second pipe body 3b are connected by a screwing element or a buckle, the one-way valve 4 is fixed between the first pipe body 3a and the second pipe body 3b.

[0042] The above only describes the exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by referring to the content of the present application and the drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
