The existing open pluggable computer module (Open Pluggable Specification, OPS) or embedded PC module is generally installed in the rear shell of the display module, and is fixed on the back plate of the display module through fixing structures such as sliding rails and brackets, a protective shell is arranged outside the OPS or PC, an air inlet and an air outlet are formed in the protective shell, and heat generated by a CPU and a GPU is taken away through air sucked by a fan. However, due to the need of plugging the OPS or the PC, a certain gap is reserved between the protective shell arranged outside the OPS or the PC and the rear shell of the display module, the air inlet on the protective shell is not sealed with the inner cavity of the rear shell, and due to the fact that the board card is arranged in the inner cavity of the rear shell, the heating value is large, the air temperature in the cavity of the rear shell is high, hot air transmitted from the inner cavity of the rear shell can be sucked into the OPS or the PC under the action of the fan, and the heat dissipation effect of the OPS or the PC is reduced due to the fact that the air inlet temperature of the fan is increased, and the performance of the OPS or the PC is further affected.

The display device that this application provided includes display module assembly, housing assembly and pluggable computer module, but housing assembly includes backplate, backshell and wind path spare, but pluggable computer module hides and sets up in the backshell, but pluggable computer module includes fan radiator unit and circuit board subassembly, corresponds on backshell and the protective housing and is provided with the air intake that is used for ventilating, and fan radiator unit inhales the protective housing with external normal atmospheric temperature air through this air intake, and the high temperature air in the protective housing is discharged by the air outlet. The air duct piece is used for blocking heat generated by other boards in the rear shell from being sucked into the protective shell by the fan radiating component, so that only outside air can enter, and the radiating performance of the pluggable computer module is improved.

The following describes the technical scheme of the present invention and how the technical scheme of the present invention solves the above technical problems in detail with specific embodiments. It should be noted that the following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.

The application provides a display device 100, as shown in fig. 1-6, comprising a display module 110, a housing assembly 120 and a pluggable computer module 130, wherein the housing assembly 120 comprises a back plate 121, a back shell 122 and an air duct member 123, the display module 110, the back plate 121 and the back shell 122 jointly enclose a cavity 124, the pluggable computer module 130 is accommodated in the cavity 124, and a first air inlet 1221 is arranged on the back shell 122; the pluggable computer module 130 comprises a protective shell 131, a fan radiating component 132 and a circuit board component 133, wherein the circuit board component 133 and the fan radiating component 132 are arranged in the protective shell 131, and the protective shell 131 is provided with a second air inlet 1311 facing the fan radiating component 132; the space 140 is arranged between the protective shell 131 and the inner wall of the rear shell 122, the air duct piece 123 is arranged in the space 140, the first end of the air duct piece 123 is enclosed outside the edge of the second air inlet 1311, the second end extends to the first air inlet 1221, and the air duct piece 123 is internally provided with an air duct 1231 communicated with the first air inlet 1221 and the second air inlet 1311.

It should be noted that, a certain space 140 is generally provided between the housing and the protective case 131 of the pluggable computer module 130 for facilitating the plugging. In addition to the pluggable computer module 130, other circuit boards 111 are disposed inside the rear case 122 of the display device 100, and these boards 111 also generate heat when the display device 100 is in operation, so that the air temperature in the rear case 122 is high. If the space 140 between the rear case 122 and the protective case 131 is unobstructed, the heat generated by the board card 111 in the rear case 122 is sucked into the protective case 131 of the pluggable computer module 130 together when the fan heat dissipation assembly 132 in the protective case 131 sucks in the outside air, resulting in poor heat dissipation effect in the pluggable computer module 130.

In order to solve the problem, the air duct member 123 is disposed in the rear case 122, the air duct member 123 is filled in the space 140 between the protective case 131 and the rear case 122, it can be understood that the air duct member 123 is a hollow cylindrical structure with two open ends, the hollow part is an air duct 1231, one end opening of the air duct member 123 encloses the edge of the second air inlet 1311 disposed on the protective case 131, the other end extends to the rear case 122, and the opening of the other end is communicated with the first air inlet 1221 disposed on the rear case 122, namely, the first air inlet 1221 is communicated with the second air inlet 1311 through the air duct member 123. When the display device 100 works, the fan heat dissipation assembly 132 sequentially sucks the external air into the protective housing 131 through the first air inlet 1221, the air duct member 123 and the second air inlet 1311, and the temperature of the external air is lower than that of the internal air of the protective housing 131, so that the temperature of the external air can be reduced as the circuit board assembly 133 in the protective housing 131. It should be noted that, the air duct member 123 is disposed on the rear housing 122, so that the heat dissipation of all the adapted pluggable computer modules 130 can be optimized in the same manner, i.e. after any type of pluggable computer module 130 is installed, the air duct member 123 can play the same role, and has very strong adaptability.

It can be appreciated that the air duct member 123 directly communicates the first air inlet 1221 with the second air inlet 1311, and isolates the second air inlet 1311 from other spaces in the rear case 122 where the board card 111 is disposed, so that heat generated by the board card 111 is prevented from entering the protective case 131, and heat dissipation performance of the pluggable computer module 130 is improved.

In an alternative embodiment, as shown in fig. 1-6, the second end of the air duct member 123 covers a portion of the first air inlet 1221.

It will be appreciated that the first end of the air duct 123 must entirely cover the second air inlet 1311 on the protective case 131, so as to ensure that the second air inlet 1311 and the space in the rear case 122 where the board card 111 is disposed are isolated from each other. The second end of the air duct member 123 only needs to be connected to the first air inlet 1221 on the rear case 122, and even if the first air inlet 1221 is partially covered, the air from the outside can be sucked into the protective case 131.

For example, when the radial width of the second air inlet 1311 is smaller than the radial width of the first air inlet 1221, and the radial width of the air duct member 123 is uniform, the second end of the air duct member 123 can only partially cover the first air inlet 1221, so that the heat generated by the board card 111 is prevented from entering the protective case 131, and the structure of the air duct member 123 is simpler and easier to manufacture, and it can be understood that the air duct member 123 has a hollow cylindrical structure with uniform radial width.

It is understood that the shape of the first air inlet 1221 and the second air inlet 1311 may be any shape, but is not limited to a circular shape or a square shape, and the cross-sectional shape of the air duct member 123 may be various, but it is required that one end of the air duct member 123 covers the second air inlet 1311 and the other end is communicated with the first air inlet 1221.

In one possible embodiment, as shown in fig. 1-6, a first end of the air channel member 123 abuts against the protective shell 131, and a second end of the air channel member 123 abuts against the rear shell 122.

It should be noted that, in order to prevent the heat generated by other boards 111 in the rear case 122 from entering the pluggable computer module 130, a sealing structure should be formed between the air duct member and the protective case 131 and between the air duct member and the rear case 122, i.e. one end of the air duct member 123 should be abutted against the protective case 131 and the other end should be abutted against the rear case 122, so the sealing performance of the air duct member 123 can be ensured, and the heat generated by other boards 111 is prevented from entering the pluggable computer module 130 to the greatest extent.

In one embodiment, the radial width of the air duct 1231 inside the air duct member 123 is greater than or equal to the radial width of the second air intake 1311.

It will be appreciated that since the duct member 123 needs to fully cover the second air inlet 1311, the radial width of the duct 1231 should be no less than the radial width of the second air inlet 1311. When the radial width of the air duct 1231 is equal to the radial width of the second air inlet 1311, a higher process accuracy is required in manufacturing and installing the air duct member 123 such that the air duct member 123 just surrounds the second air inlet 1311. When the radial width of the air duct 1231 is greater than the radial width of the second air inlet 1311, the air duct 123 is easier to be operated in the process to fully surround the second air inlet 1311, so that the process error is easier to be avoided, and the sealing reliability is improved.

In addition, the radial width of the air channel member 123 should be smaller than the width of the rear case 122 in this direction, and the air channel member 123 should be disposed so as to avoid other parts disposed in the rear case 122, and furthermore, the card 111 in the rear case 122 should be disposed at a position other than the air channel member 123 in the rear case 122.

Illustratively, an end of the air duct member 123 near the rear housing 122 encloses the edge of the first air inlet 1221, and the radial width of the air duct 1231 matches the radial width of the first air inlet 1221.

It will be appreciated that the radial width of the air duct 1231 is set to be matched with the first air opening, that is, the radial direction of the air duct 1231 is equal to or slightly larger than the radial width of the first air inlet 1221, so that, on one hand, the area of the air inlet covered by the air duct member 123 is maximized, so that air intake is smoother, and on the other hand, the occupied area of the air duct member 123 in the cavity 124 of the rear housing 122 can be reduced as much as possible, so as to avoid interference with other components.

It should be noted that, as shown in fig. 5 to 6, the sizes of the first air inlet 1221 and the second air inlet 1311 may be the same or different, and the air duct member 123 may be configured to have a uniform or gradual inner diameter of the air duct 1231 according to the relative sizes of the first air inlet 1221 and the second air inlet 1311, which is not limited herein.

Alternatively, the air channel member 123 is an elastic member. The air duct member 123 has elasticity, and can be filled between the rear shell 122 and the protective shell 131 of the pluggable computer module 130 in an interference manner, so that the air duct member 123 is tightly abutted against the rear shell 122 and the air duct member 123 and the protective shell 131, thereby realizing reliable tightness, and avoiding the heat emitted by other boards 111 in the rear shell 122 from entering the protective shell 131 to influence the working performance of the pluggable computer module 130.

The air duct member 123 is, for example, a rubber member, a silicone member, or a foam member. These materials have good sealing properties and high elasticity, and can meet the sealing requirement of the air duct member 123.

In addition, as shown in fig. 3, the pluggable computer module 130 further includes a detachable frame member 134, the frame member 134 and the protective case 131 enclose a receiving cavity together, and the circuit board assembly 133 and the fan heat dissipation assembly 132 are both disposed in the receiving cavity; the frame member 134 is provided with a first air outlet 1341, and the first air outlet 1341 is used for exhausting hot air in the accommodating cavity.

It should be noted that, the protective housing 131 and the frame member 134 of the pluggable computer module 130 are enclosed together to form a complete outer housing, and the frame member 134 and the protective housing 131 together form a receiving cavity, so as to realize exchange of external air and hot air in the protective housing 131, and a first air outlet 1341 is provided on the frame member 134, so that the air with a higher temperature in the protective housing 131 is discharged from the first air outlet 1341.

It can be appreciated that the rear case 122 of the display device 100 is also provided with a second air outlet, and the hot air in the protective case 131 is discharged from the first air outlet 1341 on the frame member 134 and then discharged to the outside air through the second air outlet on the rear case 122.

In addition, it should be noted that, since the frame member 134 is located at a side of the pluggable computer module 130 and the protective case 131 is located at a front surface of the pluggable computer module 130, the directions of the frame member 134 and the protective case 131 are different, the second air inlet 1311 is provided on the protective case 131, and the first air outlet 1341 is provided on the frame member 134, so that the second air inlet 1311 and the first air outlet 1341 face different directions, and the heat generated from the first air outlet 1341 of the protective case 131 can be prevented from being directly sucked into the second air inlet 1311, thereby further improving the heat dissipation effect of the pluggable computer module 130.

Similarly, the second air outlet on the rear housing 122 of the display device 100 should also face in a different direction from the first air inlet 1221, so as to avoid the hot air emitted from the second air outlet of the rear housing 122 from being directly sucked into the first air inlet 1221.

In one embodiment, as shown in fig. 2-6, the first air inlet 1221 and the second air inlet 1311 are of a screen type structure. For example, a plurality of ventilation holes are respectively arranged at intervals in a certain area of the rear case 122 and the protective case 131, and the plurality of ventilation holes respectively form a first air inlet 1221 and a second air inlet 1311 of the filter mesh type. Because the fan heat dissipation assembly 132 has a certain suction standing force, when the fan heat dissipation assembly 132 sucks the external air, the external foreign matters may be sucked into the first air inlet 1221 and the second air inlet 1311 together, which affects the normal operation of the pluggable computer module 130. Compared with a large air inlet, the filter screen type air inlet has smaller aperture of each vent hole, can well resist the entry of foreign matters, and can not weaken the smooth degree of air suction of the fan radiating component 132 as long as the quantity of the vent holes is enough, so that the filter screen type air inlet has the function of blocking the external foreign matters while guaranteeing the air inlet quantity.

In another embodiment, as shown in fig. 2 and 3, the back plate of the display module 110 is provided with a fixing bracket 150, one of the fixing bracket 150 and the protective shell 131 is provided with a sliding slot, the other end is provided with a sliding rail, and the pluggable computer module 130 is fixed on the back surface of the display module 110 through the sliding slot and the sliding rail in a matching manner.

It should be understood that this embodiment only shows one possible installation manner of the pluggable computer module 130, and other schemes for implementing pluggable installation of the computer module can be adopted, such as a clamping connection, etc., which will not be described in detail herein.

The application provides a display device 100, which comprises a display module 110, a shell assembly 120 and a pluggable computer module 130, wherein the shell assembly 120 comprises a back plate 121, a back shell 122 and an air duct piece 123, the display module 110, the back plate 121 and the back shell 122 jointly enclose a cavity 124, the pluggable computer module 130 is accommodated in the cavity 124, and a first air inlet 1221 is formed in the back shell 122; the pluggable computer module 130 comprises a protective shell 131, a fan radiating component 132 and a circuit board component 133, wherein the circuit board component 133 and the fan radiating component 132 are arranged in the protective shell 131, and the protective shell 131 is provided with a second air inlet 1311 facing the fan radiating component 132; the space 140 is arranged between the protective shell 131 and the inner wall of the rear shell 122, the air duct piece 123 is arranged in the space 140, the first end of the air duct piece 123 is enclosed outside the edge of the second air inlet 1311, the second end extends to the first air inlet 1221, and the air duct piece 123 is internally provided with an air duct 1231 communicated with the first air inlet 1221 and the second air inlet 1311.
