Description

[Technical Field]

[0001] This invention relates to a structure that covers a heat source. [Background technology]

[0002] Conventionally, in devices equipped with a heat source, such as image forming apparatuses that have a fixing device for fixing transfer toner, equipment for heat dissipation and cooling is provided to suppress high temperatures around the heat source and inside the housing that houses the heat source. For example, Patent Document 1 discloses a heat dissipation structure in which outside air is introduced into the image forming apparatus by a cooling fan and discharged outside the image forming apparatus by a heat dissipation fan. [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2007-249156 [Patent Document 2] Japanese Patent Publication No. 2020-34886 [Overview of the project] [Problems that the invention aims to solve]

[0004] Incidentally, a display device has been proposed in which a panel member is positioned between the display device and the decorative sheet, and an opening is provided in the panel member, thereby making the display information of the display device visible through the opening and the decorative sheet (see, for example, Patent Document 2).

[0005] In such display devices, if the heat dissipation from the heat source is poor, and the enclosure components, such as the panel, are made of acrylic, it can cause the corners of the acrylic to lift or accelerate deformation of the enclosure, leading to poor visibility. In addition, the heat generated from the heat source can cause the acrylic panel on the front of the monitor to warp in the opposite direction, pushing out the decorative sheet and resulting in a stepped appearance on the lower part of the monitor. Furthermore, high temperatures can cause the monitor, which is the heat source, to malfunction, making it an undesirable environment for monitor installation.

[0006] While it is conceivable to install cooling fans inside the enclosure of the display device, a better heat dissipation method was desired, especially for wall-mounted display devices, considering factors such as exhaust fumes from the cooling fan, the noise it makes, and the limited space it occupies within the enclosure.

[0007] Therefore, this invention was made to solve the above-mentioned unresolved problems and aims to provide a structure that can efficiently dissipate heat. [Means for solving the problem]

[0008] To achieve the above objective, according to one aspect of the present invention, a structure is provided that covers a heat source mounted on a wall, and has a housing comprising a front wall provided facing the wall on either side of the heat source, and a pair of side walls extending in the direction of the wall from each of the left and right ends of the front wall, wherein the housing forms a heat dissipation vent above the heat source in a front view, together with the wall, which is enclosed by the wall and the housing. [Effects of the Invention]

[0009] According to one aspect of the present invention, a structure with a simple structure and high heat dissipation effect can be provided. [Brief explanation of the drawing]

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] In the following description of the drawings, identical or similar parts are denoted by identical or similar reference numerals. It should be noted that the drawings are schematic, and the relationship between thickness and planar dimension, the ratio of thickness of each layer, and the like differ from actual conditions. Therefore, specific thicknesses and dimensions should be determined in consideration of the following description. Further, it is a matter of course that the drawings include portions having different dimensional relationships and ratios from each other.

[0013] Furthermore, the embodiments described below illustrate devices and methods for realizing the technical concept of the present invention, and the technical concept of the present invention does not limit the materials, shapes, structures, arrangements, etc., of the components to those described below. The technical concept of the present invention can be modified in various ways within the technical scope defined by the claims described in the patent claims. (Decorative sheet 10)

[0014] Figure 1 shows the decorative sheet 10. As shown in Figure 2, this decorative sheet 10 is used on the display panel (structure) 100, positioned in front of the display medium 110, and when not in use, it blends seamlessly with the wall surface and conceals the display medium 110. (Each layer of the decorative sheet 10)

[0015] As shown in Figure 1, the decorative sheet 10 is constructed by sequentially laminating the following three layers.

[0016] The following layers will be discussed later.

[0017] (1) Transparent sheet substrate 20

[0018] (2) Pattern layer 30

[0019] (3) Concealing layer 40

[0020] Furthermore, the layers of the decorative sheet 10 are not limited to (1) to (3) described above; for example, a protective layer may be provided on the outermost layer of the decorative sheet 10. (Layering order of each layer of decorative sheet 10)

[0021] The three layers constituting the decorative sheet 10 are laminated in the order of transparent sheet substrate 20 / concealing layer 40 / pattern layer 30, for example, as shown in Figure 1. At this time, the concealing layer 40 is positioned on the display medium 110 side (direction of arrow A) relative to the pattern layer 30. (Display panel 100)

[0022] As shown in Figures 2 and 3, the display panel 100 comprises the following parts.

[0023] The following parts will be discussed later.

[0024] (1)Display medium 110

[0025] (2) Construction wall 120

[0026] (3) Enclosure 130 (Transparent sheet substrate 20)

[0027] The transparent sheet substrate 20 serves as a support for the decorative sheet 10. While any transparent resin can be widely used, it is preferable to use a material with some heat resistance, such as PET (polyethylene terephthalate), because of the heat from the display medium 110. Specifically, for the transparent sheet substrate 20, for example, PET with a thickness of 200 μm is used.

[0028] By using a transparent sheet substrate 20 for the decorative sheet 10, the transparency of the decorative sheet 10 can be increased, improving visibility. This allows the display medium 110 to be used at low brightness, suppressing the temperature rise caused by the display medium 110 and improving visibility. In other words, by using a regular liquid crystal monitor for the display medium 110 and displaying at low brightness, the rise in surface temperature can be suppressed. By using a low-brightness display for the display medium 110, the surface temperature could be kept below 45°C, which is the temperature at which low-temperature burns occur.

[0029] Furthermore, by using the transparent sheet substrate 20, visibility can be improved even in low-brightness displays.

[0030] Furthermore, since low-brightness display is sufficient for the display medium 110, the use of a high-brightness monitor becomes unnecessary, thus reducing component costs. (Concealing layer 40)

[0031] The concealing layer 40 is formed on either side of the transparent sheet substrate 20, in this embodiment 1, on the surface opposite to the display medium 110, as shown in Figure 1, using a printing method. It is provided for the purpose of concealing the color of the display medium 110 while allowing a clear image to be displayed transparently.

[0032] The opacifying layer 40 preferably has a certain degree of light transmittance and openings 41 where no pigment is applied.

[0033] The visible light transmittance of the concealing layer 40 should preferably be between 10% and 70%.

[0034] If the percentage is less than 10%, the display visibility is poor, and if it exceeds 70%, the concealment is poor. (Placement of concealment layer 40)

[0035] The concealing layer 40 is always positioned on the display medium 110 side (in the direction of arrow A) relative to the pattern layer 30.

[0036] In contrast, if the concealing layer 40 is positioned on the observation side (in the direction of arrow B) of the pattern layer 30, the pattern layer 30 may become invisible or difficult to see. (Printing method for the opacity layer 40)

[0037] The opacity layer 40 was printed using an inkjet device, for example, with a white ink containing titanium dioxide. Specifically, the opacity layer 40 is printed on the back of the pattern layer 30, for example, with solid white printing.

[0038] While an inkjet printer was used as an example of a printing method, it is not limited to this.

[0039] In addition to inkjet printing, the prints are formed by applying various other printing methods, such as gravure printing, offset printing, letterpress printing, flexographic printing, screen printing, and electrostatic printing.

[0040] Furthermore, the printing method is not limited to the printing methods exemplified above. Any conventionally known image forming means can be applied, such as hand-drawing, suminagashi (marbling), transfer, photography, electrophotography, photosensitive resin, vacuum deposition, chemical corrosion, thermochromic, and discharge destruction. (Opening 41)

[0041] The opening 41 is the part that is not coated with pigment.

[0042] In other words, the concealing layer 40 is a layer made up of the following parts.

[0043] (1) Colored layer

[0044] The colored layer is the part to which the pigment and resin have been applied.

[0045] While various colors can be applied to the colored layer, bright colors are preferable, with white being the most desirable.

[0046] (2) Opening 41

[0047] The openings 41 are scattered throughout the colored layers, and are unpainted areas without pigment or resin. In other words, the openings 41 are empty spaces or gaps that are not printed.

[0048] In other words, when observing the surface with two layers, the transparent sheet substrate 20 and the concealing layer 40, the image is that of a part where you can directly see through the opening 41 to the other side.

[0049] The opening ratio of the opening 41 should preferably be between 2% and 40%.

[0050] If the density is less than 2%, the display visibility is poor, and if it exceeds 40%, the concealment is poor.

[0051] By providing an opening 41 in the concealing layer 40, the display medium 110 can be concealed while suppressing color changes when it is not displayed.

[0052] Furthermore, by providing openings 41 in the concealing layer 40, the transparency of the decorative sheet 10 can be increased, improving visibility. As a result, the display medium 110 can be used at low brightness, suppressing the temperature rise caused by the display medium 110 and improving visibility.

[0053] The opaque layer 40, including the colored layer and the opening 41, has an overall visible light transmittance of 10% to 70%.

[0054] If the percentage is less than 10%, the display visibility is poor, and if it exceeds 70%, the concealment is poor. (Picture layer 30)

[0055] The pattern layer 30 is formed on the surface of the opacity layer 40 using a printing method and is provided for the purpose of adding design to the decorative sheet 10.

[0056] The pattern layer 30 may be applied to the entire surface, provided that it has a certain degree of light transmittance.

[0057] Since the pattern layer 30 does not require an "opening 41" like the concealing layer 40, it is possible to create a highly detailed design.

[0058] Specifically, the pattern layer 30 was printed using an inkjet device, and the "wood grain pattern" was printed using four colors of ink, such as cyan, magenta, yellow, and black.

[0059] Although an inkjet device was used as an example of a printing method for the pattern layer 30, the method is not limited to this, and various printing methods can be applied, similar to the opacity layer 40. (Pattern of layer 30)

[0060] While "wood grain pattern" is given as an example of the pattern type for pattern layer 30, it is not limited to this and can be any type depending on the purpose of use and the user's preference. In addition to wood grain, other common patterns include stone patterns and abstract patterns. The type of pattern is not limited to the examples given above, and may also include, for example, full-surface solid printing. (Display medium 110)

[0061] The display medium 110 is placed on the back side of the decorative sheet 10, as shown in Figures 2 and 3. For example, the display medium 110 has a density of 300 cd / m². 2 More than 1200cd / m 2 The following general-purpose LCD displays (700cd) can be used.

[0062] The display medium 110 is fixed to the construction wall 120, for example, by a mounting bracket 120a.

[0063] Although a liquid crystal display (LCD) is given as an example of the display medium 110, it is not limited to this, and cathode ray tube displays (CRTs), plasma displays (PDPs), electroluminescent displays (ELDs), and field emission displays (FEDs) may also be used. (Construction wall 120)

[0064] The construction wall 120 is for supporting the housing 130 in addition to the display medium 110.

[0065] The display medium 110 is fixed to the construction wall 120, for example, by mounting brackets 120a. The display medium 110 is positioned at approximately the user's eye level, and the housing 130 is formed to a size that can cover the entire display medium 110. The construction wall 120 may be an existing wall. That is, the display panel 100 may be constructed by fixing the display medium 110 and the housing 130 to an existing wall, or the display panel 100 may be constructed including the construction wall 120 so that the display panel 100 can be installed as a standalone unit in any location. (Cabinet 130)

[0066] The housing 130 is made of a material that ensures strength, such as sheet metal, and is fixed to the construction wall 120 by a jig 120b.

[0067] As shown in Figures 2 to 4, the enclosure 130 surrounds the front, left and right sides, and top of the display medium 110, and the enclosure 130 is slightly shorter in length than the height of the construction wall 120. However, the vertical length of the enclosure 130 is not limited to this, and it should be at least long enough to cover the display medium 110.

[0068] The housing 130 has a front wall 130a, left and right side walls 130b, and a reinforcing plate 130c at its upper end. Furthermore, it has support walls 130d and 130e located slightly above and slightly below the window portion 131, which will be described later, when viewed from the front.

[0069] The front wall 130a of the enclosure 130 is a long, rectangular plate in the vertical direction, located in front of the display medium 110, and its front surface is free of irregularities and highly flat.

[0070] Furthermore, the back surface of the front wall 130a is also formed flat so as to face the surface of the display medium 110.

[0071] The upper edge of the front wall 130a is positioned above the upper edge of the display medium 110, and its width is also set to be slightly larger than the width of the display medium 110.

[0072] The left and right side walls 130b extend toward the display medium 110, with their planes bent in a channel (U) shape from the left and right ends of the front wall 130a.

[0073] The reinforcing plate 130c, and the support walls 130d and 130e have the same shape as shown in Figures 4 and 5. The reinforcing plate 130c is provided at the upper end of the housing 130, in contact with the front wall 130a and the left and right side walls 130b. The support wall 130d is provided in contact with the front wall 130a and the left and right side walls 130b at a position slightly above the upper end of the window section 131, and the support wall 130e is provided in contact with the front wall 130a and the left and right side walls 130b at a position slightly below the lower end of the window section 131. In Figure 5, (a) is a plan view of the reinforcing plate 130c, (b) is a side view, (c) is a front view, and (d) is a perspective view.

[0074] Furthermore, as shown in Figure 4, a mounting member 134a for attaching an adjuster 134 is provided near the lower end of the housing 130. The mounting member 134a is formed in a shape roughly resembling the Japanese katakana character "コ" in plan view and is fixed in contact with the front wall 130a and the left and right side walls 130b. The portion of the mounting member 134a that contacts the left and right side walls 130b is formed to be wider, and the adjuster 134 is attached to the wider portion. By providing the adjuster 134, a gap is created between the lower end of the housing 130 and the mounting surface.

[0075] Since the reinforcing plate 130c and the support walls 130d and 130e have the same shape, the reinforcing plate 130c will be described here.

[0076] As shown in Figures 4 to 6, the reinforcing plate 130c, in plan view, is in contact with each of the left and right side walls 130b and the front wall 130a. It has the shape of an isosceles triangle cut out from a rectangle with one long side being the part in contact with the front wall 130a and the parts in contact with the left and right side walls 130b being the short sides, with the apex located in the center of the longitudinal direction and slightly inward from the long side on the front wall 130a side towards the other long side, and a part of the other long side as the base. In addition, the parts of the reinforcing plate 130c that are in contact with the front wall 130a and the parts that are in contact with the side walls 130b are bent into the shape of the letter "L". When the housing 130 is attached to the construction wall 120, a heat dissipation hole 133 is formed surrounded by the reinforcing plate 130c and the construction wall 120, and the heat dissipation hole 133 has the shape of an isosceles triangle in plan view.

[0077] Here, the reinforcing plate 130c is formed such that the area of ​​the heat dissipation holes 133 in a plan view is 30% or more but less than 100% of the area of ​​the opening enclosed by the housing 130 and the construction wall 120 in a plan view.

[0078] Furthermore, the reinforcing plate 130c has a cutout hole 130cc formed therein. By providing this cutout hole 130cc, the shape of the heat dissipation holes can be changed after the housing 130 has been installed, according to the environment of the installation location. This makes it possible to change the area and shape of the heat dissipation holes 133 according to the installation environment of the display panel 100.

[0079] The reinforcing plate 130c is formed from sheet metal having the same thickness as the housing 130, for example, and is manufactured simultaneously with the housing 130 by copper plate pressing.

[0080] The reinforcing plate 130c has a shape in which, for example, in a plan view, an isosceles triangle with a base of 661 mm and a depth (i.e., height) of 128 mm is cut out from a rectangle having a length of 665 mm between the left and right ends that are in contact with the side wall 130b and a width length of 130 mm in contact with the side wall 130b, with its vertices located at two points 2 mm inward from each of the left and right side walls 130b, and at a point 2 mm inward from the long side on the front wall 130a side in the longitudinal center of the rectangle.

[0081] In this case, the opening area of ​​the heat dissipation vent 133 is 42.304 mm². 2 Therefore, the area of ​​the opening enclosed by the casing 130 and the construction wall 120 is 86.450 mm². 2 Since ((635+15+15)×(115+15)), the ratio of the opening area of ​​the heat dissipation holes 133 to the area of ​​the opening enclosed by the housing 130 and the construction wall 120 is approximately 50% (48.9%).

[0082] The reinforcing plate 130c is attached to the housing 130 by screws, or by known methods such as adhesive or double-sided tape.

[0083] The notch structure of the reinforcing plate 130c can be arbitrarily set as long as it has an isosceles triangular shape that satisfies the condition of the opening area of ​​the heat dissipation hole 133. Furthermore, from the viewpoint of reinforcing the housing 130 described later, it is preferable that the reinforcing plate 130c is in contact with the front wall 130a and the left and right side walls 130b, and is in contact with the entire width direction of the front wall 130a and the left and right side walls 130b.

[0084] Furthermore, the thickness of the sheet metal forming the reinforcing plate 130c can be arbitrarily set according to the required strength. (Various parts of the front wall 130a)

[0085] The front wall 130a includes the following parts, as shown in Figures 2 and 3.

[0086] (1) Window section 131

[0087] (2) Transparent plate 132 (Window section 131)

[0088] As shown in Figures 2 and 3, the window section (display window section) 131 faces the display surface of the display medium 110 fixed to the construction wall 120 and is formed to penetrate it.

[0089] The window portion 131 is an opening smaller than the display area in order to conceal the area around the display surface of the display medium 110.

[0090] Although the window section 131 is formed relatively high on the front wall of the housing 130, it is not limited to this position and may be formed in the center, although this is not shown in the illustration. (Transparent plate 132)

[0091] The transparent plate 132 is fitted and fixed into the window portion 131 of the housing 130, and is made of a highly transparent material such as acrylic, glass, or PET. Furthermore, the thickness of the transparent plate 132 is set to be between 2 mm and 5 mm in order to maintain strength and transparency.

[0092] The size of the transparent plate 132 is made smaller than the window portion 131 of the front wall 130a in order to align its surface with the front wall 130a, so that it fits into the window portion 131 and is flush with the front surface of the front wall 130a.

[0093] Furthermore, the thickness of the transparent plate 132 is greater than that of the front wall 130a, and its rear surface faces the display surface of the display medium 110.

[0094] Since the front wall 130a is provided with a window 131, the portion of the display medium 110 other than the display surface is covered by the front wall 130a, and as a result, unevenness and color differences caused by partial material differences between the display medium 110 and the housing 130 can be concealed. (Effects / Actions)

[0095] The display panel 100 has its front and sides covered by the housing 130, and the space enclosed by the housing 130 and the installation wall 120 is relatively narrow. The display medium 110 is a heat source, but since the top and bottom ends of the housing 130 are open, a heat exhaust path is formed in the space enclosed by the housing 130 and the installation wall 120, exiting from the bottom end to the top end of the housing 130. Therefore, it is possible to suppress temperature rise and other changes within the space enclosed by the housing 130 and the installation wall 120, thereby suppressing changes in the temperature environment. As a result, it is possible to suppress high temperatures inside the housing 130, such as around the display medium 110, due to heat exhaust, thereby suppressing deformation of the housing 130 and malfunction of the display medium 110. As a result, it is possible to reduce the risk of malfunction and low-temperature burns caused by the temperature rise of the display medium 110 as a heat source.

[0096] Furthermore, it is conceivable to provide the heat dissipation holes 133 near the display medium 110, which is the heat source. However, in the display panel 100, they are located at the upper end of the housing 130, above the display medium 110 when viewed from the front. Since warm air tends to move upward, by considering the airflow around the display medium 110, which is the heat source, and positioning the heat dissipation holes 133 above the display medium 110, heat can be dissipated efficiently, and the temperature near the display medium 110, which is the heat source, can be suppressed from rising.

[0097] Furthermore, as shown in Figure 6, the reinforcing plate 130c has a shape in which an isosceles triangle is cut out from a rectangle that is in contact with each of the pair of side walls 130b and the front wall 130a at the upper end of the housing 130, forming part of the heat dissipation holes 133 and in contact with the front wall 130a and side walls 130b of the housing 130.

[0098] Here, the housing 130 has a shape resembling the Japanese katakana character "コ" when viewed from above. If a force is applied to the front wall 130a of such a "コ"-shaped housing 130, the front wall 130a may deform and dent. In particular, in the case of the display panel 100 shown in Figure 2, since it is installed so as to become part of the wall, if that wall faces a passageway, there is a possibility that people or objects may collide with the front wall 130a of the housing 130.

[0099] In the display panel 100 according to this embodiment, the reinforcing plate 130c is shaped to be in contact with the front wall 130a and the left and right side walls 130b, respectively, as described above. Therefore, the reinforcing plate 130c acts to suppress deformation of the housing 130, including the front wall 130a, thereby reinforcing the housing 130.

[0100] In particular, the portions of the reinforcing plate 130c that contact the left and right side walls 130b become the parts that withstand the force when a person or other object collides with the front wall 130a, thereby preventing or reducing deformation of the front wall 130a.

[0101] In this case, in order to reinforce the housing 130, reducing the area of ​​the isosceles triangle cut out to create the reinforcing plate 130c and increasing the area of ​​the reinforcing plate 130c would further suppress the deformation of the housing 130. However, if the area of ​​the reinforcing plate 130c is increased, the opening of the heat dissipation hole 133 will become smaller, which may prevent sufficient heat dissipation.

[0102] However, in the above embodiment, the opening area of ​​the heat dissipation holes 133 is set to be 30% or more but less than 100% of the opening area of ​​the opening consisting of the housing 130 and the construction wall 120. Therefore, even when the reinforcing plate 130c is provided, sufficient heat can be dissipated. In other words, from the viewpoint of heat dissipation, it is preferable to use the opening consisting of the housing 130 and the construction wall 120 as a heat dissipation hole without providing the reinforcing plate 130c. However, since the opening area of ​​the heat dissipation holes 133 is set to be large enough to obtain a heat dissipation effect, the strength of the housing 130 can be ensured and a sufficient heat dissipation effect can be obtained, which is advantageous in terms of quality assurance and area.

[0103] Furthermore, the reinforcing plate 130c is provided with a hole 130cc. By utilizing this hole 130cc, the shape can be adjusted to allow for sufficient heat dissipation according to the environment of the installation site, even after the display panel 100 has been installed, thus enabling flexible adaptation to each installation location. <Variation> (1) The reinforcing plate 130c is not limited to a shape in which an isosceles triangle is cut out from a rectangular plate, as shown in Figures 5 and 6. For example, as shown in Figure 7, the reinforcing plate 130c may be made into a shape in which a rectangle is cut out from a rectangle that is in contact with the front wall 130a and the left and right side walls 130b, with a part of one of the longer sides on the side facing the construction wall 120 as the other longer side, thereby forming a rectangular opening in plan view. The shape of the reinforcing plate 130c can be arbitrarily set as long as the area of ​​the heat dissipation hole 133 in plan view is 30% or more and less than 100% of the area of ​​the opening enclosed by the housing 130 and the construction wall 120 in plan view, and can be set considering the installation conditions of the housing 130 and the ease of processing. By setting the reinforcing plate 130c to fall within this range, sufficient heat dissipation capacity can be achieved. For example, if the width of the front wall 130a is 800 mm, and the widths of the left and right side walls 130b are 72.5 mm, then the area of ​​the opening enclosed by the housing 130 and the construction wall 120 is 58,000 mm². 2 In this case, the shape of the opening of the heat exhaust hole 133, surrounded by the reinforcing plate 130c and the construction wall 120, is 725 mm wide and 40 mm deep, and the opening area of ​​the heat exhaust hole 133 is 29,000 mm². 2 If it is rectangular in shape, the area of ​​the heat dissipation holes 133 is (29,000 mm²). 2 ) The opening area of ​​the opening enclosed by the housing 130 and the construction wall 120 is 58,000 mm². 2 Since it is 50% of the total, sufficient heat dissipation can be achieved. (2) In the above embodiment, a reinforcing plate 130c is provided, but in cases where the display panel 100 is installed away from a passageway, or when the possibility of collision with people or objects is low, the reinforcing plate 130c does not necessarily have to be provided. In this case, the opening enclosed by the housing 130 and the construction wall 120 becomes a heat dissipation vent, so a greater heat dissipation effect can be obtained compared to when a reinforcing plate 130c is provided. (3) As shown in Figures 2 and 3, the reinforcing plate 130c can be installed at any position that is above the display medium 110 when viewed from the front, not limited to the upper end of the housing 130. (4) In the above embodiment, the case in which the structure is applied to a display panel 100 has been described, but it is not limited to this, and can also be applied to a structure that covers a heat source mounted on a wall, such as lighting, video equipment, air conditioning equipment, or heating appliances, from the front and sides. (5) In the above embodiment, the reinforcing plate was described as being in the shape of an isosceles triangle or a rectangle cut out from a rectangle connected to the front wall 130a and a pair of side walls 130b. However, it is not limited to this, and as long as the condition is satisfied that the opening area of ​​the heat dissipation holes 133 is 30% or more but less than 100% of the opening area of ​​the opening made up of the housing 130 and the construction wall 120, the shape cut out from the rectangle connected to the front wall 130a and the pair of side walls 130b is not limited to an isosceles triangle or a rectangle. [Examples]

[0104] Examples of the present invention are described below.

[0105] The heat dissipation state was measured for three cases: when the heat dissipation holes 133 shown in Figure 6 are isosceles triangles (Example 1), when the heat dissipation holes 133 are rectangular (Example 2) as shown in Figure 7, and when there are no heat dissipation holes 133 (Comparative Example). The heat dissipation state was measured using the verification housing 130' and verification reinforcement plate 130c' shown in Figure 8. In Figure 8, (a) is a front view of the verification housing 130', and (b) is a top view of the verification housing 130'. The verification enclosure 130' comprises a front panel 101' and a support member 102' that supports the front panel 101'. A front wall 130a' is fitted into a portion of the front panel 101', and the front wall 130a' and the front panel 101' are sealed with masking tape 103'. On the side of the front panel 101' opposite the support member 102', one end of a side wall 130b' is fixed along both the left and right ends of the front wall 130a', and a rear panel 104' is fixed to the other end of the side wall 130b' so as to close the space between the left and right side walls 130b'. The verification reinforcement plate 130c' is provided above the front panel 101', penetrating the front panel 101', and is positioned so that the side of the verification reinforcement plate 130c' with a notch for forming the heat dissipation hole 133' is flush with the rear panel 104'. The lower surface of the verification reinforcement plate 130c' is in close contact with the upper ends of the left and right side walls 130b' and the upper end of the rear panel 104', thereby forming a hollow rectangular prism section surrounded by the front panel 101' including the front wall 130a', the rear panel 104', and the left and right side walls 130b'. The heat dissipation hole 133' is formed by closing the upper end of this rectangular prism section with the verification reinforcement plate 130c'. The verification housing 130' simulates the housing 130 by having this configuration. In this verification enclosure 130', a verification heat source (monitor), not shown in the figure, was attached to the rear panel 104', which, when viewed from the front, is located in the center of the front panel 101' in the left-right direction and slightly above the center in the up-down direction. In the verification enclosure 130', the front wall 130a', side wall 130b', and reinforcing plate 130c' simulate the front wall 130a, side wall 130b, and reinforcing plate 130c of enclosure 130, respectively, while the rear panel 104' simulates the construction wall 120.

[0106] The reinforcing plate 130c′ used for verification in Example 1 is a plate-like member that simulates the shape of an isosceles triangle with a base of 661 mm and a depth (i.e., height) of 128 mm, with vertices at two locations on one of the long sides of the rectangle, 2 mm inward from each of the left and right ends in the longitudinal direction, and at the center in the longitudinal direction, 2 mm inward from the other long side of the rectangle, and has an isosceles triangular slit with a base of 661 mm and a depth (i.e., height) of 128 mm. The reinforcing plate 130c′ is attached to the front panel 101′ by penetrating it, such that the end opposite to the side that forms the base of the isosceles triangular slit is on the front wall 130a′ side.

[0107] The reinforcing plate 130c' in Example 2 is formed of a plate-like member simulating a shape obtained by cutting out a rectangle having a length in the longitudinal direction of 725 mm and a length in the lateral direction of 40 mm from a rectangle having a long side with a length corresponding to the length between the left and right side walls 130b' and a short side with a length corresponding to the length in the width direction of the side wall 130b', and has a rectangular slit with a long side of 725 mm and a short side of 40 mm. The reinforcing plate 130c' in Example 2 is attached through the front panel 101' such that the side opposite to the side where the rectangular slit is formed faces the front wall 130a' side.

[0108] In the comparative example, a plate-like member without a slit was used instead of the reinforcing plate 130c'.

[0109] It should be noted that the opening area of the slit of the reinforcing plate 130c' is set to be 30% or more and less than 100% relative to the area of the opening surrounded by the front panel 101', the side wall 130b' and the rear panel 104'. During the measurement, the temperature of the test room was kept at 20 to 25°C, and the humidity was kept at around 70%. In addition, in order to reproduce the situation where the air inside the housing 130 circulates from the bottom surface to the heat exhaust holes, in the verification housing 130', any gaps that may occur between each of the front panel 101' and the rear panel 104' and the side wall 130b' were sealed with duct tape (not shown). Temperature measurement was performed every 1 hour, with the time when the monitor as a verification heat source was started defined as 0 hour. During the measurement, an infrared thermal imager was placed at a position 10 cm away from the surface of the front wall 130a' on the support member 102' side, and a temperature distribution image of the front wall 130a' was acquired. In addition, the temperature of the monitor itself as the verification heat source was separately measured, the measured temperature was taken as the maximum temperature of the monitor and plotted for each elapsed time to track the change over time.

[0110] In Example 1, the opening area of the isosceles triangular slit of the reinforcing plate 130c' for verification is 42.304 mm 2 and the area of the opening formed by the front panel 101', the rear panel 104' and the side wall 130b' is 86.450 mm 2In this case, the ratio of the opening area is 42.304 mm². 2 / 86.450mm 2 = 48.9%. Furthermore, in Example 2, the opening area of ​​the rectangular slit is 29,000 mm². 2 The area of ​​the opening, which consists of the front panel 101', the rear panel 104', and the side wall 130b', is 86.450 mm². 2 In this case, the ratio of the opening area is 29.000 mm². 2 / 86.450mm 2 = 33.5%

[0111] Figure 9(a) is a graph showing the change in the maximum monitor temperature over time in Example 1, and Figure 9(b) is a temperature distribution image of the verification housing 130' as viewed from the support member 102' side, obtained by an infrared thermal imaging device. The temperature distribution image of Example 1 shows a temperature distribution in the range of 24.4°C to 37.5°C, and the temperature in the center of the acquired temperature distribution image was approximately 33.3°C.

[0112] Figure 10(a) is a graph showing the change in the maximum monitor temperature over time in Example 2, and Figure 10(b) shows a temperature distribution image of the verification housing 130' as viewed from the support member 102' side, obtained by an infrared thermal imaging device. The temperature distribution image in Example 2 shows a temperature distribution in the range of 23.3°C to 37.5°C, and the temperature in the center of the acquired temperature distribution image was approximately 36.6°C.

[0113] Figure 11(a) is a graph showing the change in the maximum monitor temperature over time in the comparative example, and Figure 11(b) is a temperature distribution image of the verification housing 130' as viewed from the support member 102' side, obtained by an infrared thermal imaging device. In the temperature distribution image of the comparative example, a temperature distribution occurred in the range of 22.9°C to 38.1°C, and the temperature at the center of the acquired temperature distribution image, i.e., near the installation position of the verification heat source, was approximately 37.3°C. The central part of the acquired temperature distribution image is the area where the temperature is predicted to be high, which corresponds to, for example, the heat source used for verification.

[0114] In the comparative example, under a sealed condition, the maximum monitored temperature consistently remained in the high-temperature range of around 42°C throughout the 5-hour test, as shown in Figure 11. The temperature in the central part of the acquired temperature distribution image was approximately 37.3°C, confirming that not much heat was being transferred.

[0115] After performing measurements in the comparative example, verification was carried out using the reinforcing plate 130c' in Example 1, where the heat dissipation holes 133' are isosceles triangles, and the reinforcing plate 130c' in Example 2, where the heat dissipation holes 133' are rectangular. As a result, as shown in Figures 9 and 10, the maximum monitored temperature consistently remained in the high temperature range of around 42°C during the 5-hour test. Furthermore, the temperature in the central part of the acquired temperature distribution image was approximately 33.3°C for Example 1 and 36.6°C for Example 2, confirming that heat was transferred. From these results, it is considered that the temperature threshold can be kept low or the temperature rise can be slowed down.

[0116] Based on the above verification results, it was confirmed that the ratio of the opening area of ​​the exhaust vent 133', i.e., the exhaust vent 133, must be 30% or more. Furthermore, while the temperature difference between Examples 1 and 2 and the comparative example is slight during long-term use, even a slight difference raises concerns about low-temperature burns and malfunctions of the display device.
