Description

Technical Field

[0001] The present application relates to the technical field of advertising machine devices, and in particular to a heat dissipation structure and an advertising machine. Background Art

[0002] Many devices, such as advertising machines, projectors, and induction cookers, typically have built-in air-cooling devices with air inlets and outlets on their outer casings. These draw outside air in, passing through components inside the machine, such as the main control board and backlight panel, which generate significant heat when in operation. The heat-containing air is then released to the outside through the outlets. However, even with filters installed on the air inlet, dust inevitably accumulates inside the machine over time. This not only causes contamination, but also affects the internal electrical environment. In severe cases, it can shorten the lifespan of the device and cause failure.

[0003] Therefore, there is an urgent need for a new type of heat dissipation structure that can not only meet the heat dissipation requirements of the device, but also achieve a dust-proof effect to avoid affecting the electronic components inside the device. Utility Model Content

[0004] The present invention mainly aims at the above problems and proposes a heat dissipation structure and an advertising machine, aiming to solve the technical problems in the background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides a heat dissipation structure and an advertising machine, comprising a wave plate, a sealing connecting plate, and a first heat dissipation fan; the wave plate and the sealing connecting plate are arranged in the inner cavity of the shell of the electrical device; there are two sealing connecting plates, which are respectively connected to the two ends of the wave plate, and the three are connected to form a partition plate; the outer edge of the partition plate is connected to the side wall of the inner cavity of the shell of the electrical device, separating the electronic components in the inner cavity of the shell of the electrical device from the outside world; the first heat dissipation fan is used to drive air to flow on the surface of the partition plate.

[0006] Furthermore, the outer edge of the partition plate is connected to the side wall of the inner cavity of the shell of the electrical device, dividing the inner cavity of the shell of the electrical device into a first chamber and a second chamber that are not connected to each other; the electronic components of the electrical device are located in the first chamber; the second chamber is formed by the partition plate, the side wall of the shell of the electrical device and the rear cover of the electrical device; the rear cover of the electrical device is provided with a ventilation hole; the first cooling fan is located in the second chamber.

[0007] Furthermore, the sealing connection plate is a flat plate structure, and both ends of the wave plate are provided with plug-in grooves corresponding to the sealing connection plate.

[0008] Furthermore, it includes sealing plugs; a plurality of the sealing plugs are used to connect and seal the gap holes at the connection between the sealing connecting plate and the corrugated plate.

[0009] Furthermore, the cross-section of the corrugated plate has a crest and a trough profile that is V-shaped or curved.

[0010] Furthermore, the side of the corrugated plate that is not connected to the sealing connection plate is a straight side.

[0011] Furthermore, the length direction of the grooves on the wave plate is the same as the exhaust airflow direction or the blowing airflow direction of the first cooling fan in the second chamber.

[0012] Furthermore, it includes a second cooling fan, which is arranged in the chamber where the electronic components are located in the inner cavity of the electrical device housing and is located at one end of the wave plate or adjacent to the sealing connection plate.

[0013] Furthermore, a third cooling fan is included, which is arranged in the chamber where the electronic components are located in the inner cavity of the electrical device housing and is symmetrically distributed with the second cooling fan.

[0014] Furthermore, the length direction of the grooves on the wave plate is the same as the exhaust airflow direction or the blowing airflow direction of the second cooling fan and the third cooling fan in the first chamber.

[0015] Furthermore, the first cooling fan, the second cooling fan, and the third cooling fan are cross-flow impeller fans.

[0016] The present application also provides an advertising machine, comprising a heat dissipation structure as described above; further comprising a second cooling fan and a third cooling fan; further comprising a second cooling fan and a third cooling fan; the outer edge of the partition plate is connected to the side wall of the inner cavity of the shell of the advertising machine, dividing the inner cavity of the shell of the advertising machine into a first chamber and a second chamber that are not connected to each other; the back cover of the advertising machine is provided with a vent; the first cooling fan is located in the second chamber; a first spacer is provided between the display module of the advertising machine and the transparent protective layer of the advertising machine; a second spacer is provided between the display module and the partition plate; the second cooling fan and the third cooling fan are respectively provided at both ends of the display module, corresponding to fanning the first spacer and the second spacer to drive air circulation.

[0017] Compared to the prior art, the heat dissipation structure and advertising machine provided by the present invention can transfer heat from the first chamber to the partition plate. Because the partition plate is provided with a corrugated plate, which has wavy folds compared to ordinary flat plates, the corrugated plate has a larger area for the same circumference and can therefore transfer more heat. A first cooling fan located in the second chamber draws outside air into the second chamber through the air inlet vents. The air flows through the corrugated corrugated plate 1 and is then blown out of the air outlet vents to the outside, thereby removing heat generated by the corrugated plate and the first chamber during operation, achieving a heat dissipation and cooling effect.

[0018] Since the outer edge of the partition plate is connected to the side wall of the inner cavity of the shell of the electrical device, the inner cavity of the shell of the electrical device is divided into a first chamber and a second chamber that are not connected to each other, so the outside air will not enter the first chamber, and the dust particles contained therein will not enter the electronic components of the electrical device to cause dirt or malfunction. At the same time, it can also provide a certain waterproof effect for the first chamber, thereby improving the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Please refer to Figure 1 、 Figure 3 and Figure 4This embodiment provides a heat dissipation structure and an advertising machine, including a wave plate 1, a sealing connection plate 2, and a first heat dissipation fan 3; the wave plate 1 and the sealing connection plate 2 are arranged in the inner cavity of the housing of the electrical device; the sealing connection plates 2 are two in number, respectively connected to the two ends of the wave plate 1, and the three are connected to form a partition plate 150; the outer edge of the partition plate 150 is connected to the side wall of the inner cavity of the housing 4 of the electrical device, separating the electronic components in the inner cavity of the electrical device housing from the outside world; the first heat dissipation fan 3 is used to drive air to flow on the surface of the partition plate 150.

[0028] In this embodiment, the housing of the electrical device may not be provided with a back cover, and the partition plate 150 directly serves as the back cover of the housing of the electrical device. The first cooling fan 3 may be provided outside the housing of the electrical device and may be a waterproof fan.

[0029] The electrical device may be the advertising machine described below, or may be a projector, an induction cooker, a computer host or other electrical equipment.

[0030] Please refer to Figure 1 - Figure 4 This embodiment provides a heat dissipation structure and an advertising machine, including a wave plate 1, a sealing connection plate 2, and a first cooling fan 3; the wave plate 1 and the sealing connection plate 2 are arranged in the inner cavity of the housing of an electrical device; the sealing connection plates 2 are two in number, connected to the two ends of the wave plate 1 respectively, and the three are connected to form a partition plate 150; the outer edge of the partition plate 150 is connected to the side wall of the inner cavity of the housing 4 of the electrical device, dividing the inner cavity of the housing 4 of the electrical device into a first chamber 510 and a second chamber 520 that are not connected to each other; the electronic components of the electrical device are located in the first chamber 510; the second chamber 520 is formed by the partition plate 150, the side wall of the housing of the electrical device, and the rear cover plate 6 of the electrical device; the rear cover plate 6 of the electrical device is provided with a vent (not shown); the first cooling fan 3 is located in the second chamber 520.

[0031] In some embodiments, the outer contour of the partition plate 150 can be shaped like the contour of the inner side wall of the shell 4 of the electrical device; the box or cabinet is generally a regular rectangular body, and some boxes or cabinets are irregularly shaped. Then the corresponding internal contour of the partition plate 150 is also a corresponding irregular shape, so that the outer edge abuts the inner side wall of the shell 4, separating the first chamber 510 and the second chamber 520 so that they are not connected to each other.

[0032] In some embodiments, the first cooling fan 3 may be provided corresponding to the vent.

[0033] The ventilation openings include at least one air inlet and one air outlet. Depending on the direction of the fan blades of the first heat dissipation fan 3, the corresponding ventilation openings are air inlets or air outlets.

[0034] The vents are not limited to being provided on the rear cover 6 , but may also be provided on other locations of the housing 4 .

[0035] During operation, heat from the first chamber 510 is transferred to the partition plate 150. Because the partition plate 150 includes a corrugated plate 1, which has wavy folds compared to a conventional flat plate, the corrugated plate 1 has a larger surface area for a plate of the same circumference, thus transferring more heat. The first cooling fan 3, located in the second chamber 520, draws outside air into the second chamber 520 through the air intake vents. This air flows through the corrugated corrugated plate 1, strengthening air flow and convection on the surface of the partition plate 150. The air is then blown out through the air outlet vents, removing heat generated by the corrugated plate 1 and the first chamber 510 during operation, achieving a cooling effect.

[0036] Since the outer edge of the partition plate 150 is connected to the side wall of the inner cavity of the shell 4 of the electrical device, the inner cavity of the shell 4 of the electrical device is divided into a first chamber 510 and a second chamber 520 that are not connected to each other, then the outside air will not enter the first chamber 510, and the dust particles contained therein will not enter the electronic components of the electrical device to cause dirt or malfunction. At the same time, it can also provide a certain waterproof effect for the first chamber 510, thereby improving the service life of the equipment.

[0037] Example 1

[0038] The sealing connecting plates 2 at both ends of the wave plate 1 are an integral structure with the wave plate 1 and belong to the same plate. The sealing connecting plates 2 are a wavy connection structure with the wave plate 1, gradually transitioning to a straight structure. The straight structure section of the sealing connecting plate 2 is connected to the side wall of the inner cavity of the shell 4 of the electrical device, thereby separating the first chamber 510 and the second chamber 520 so that they are not connected to each other.

[0039] Example 2

[0040] The sealing connecting plates 2 at both ends of the corrugated plate 1 are not integral with the corrugated plate 1 but are three separate entities. The sealing connecting plates 2 can be connected to the corrugated plate 1 by welding, gluing, screwing, or other methods. One end of the sealing connecting plate 2 is connected to the corrugated plate 1 and has a wavy structure, while the other end gradually transitions to a straight structure.

[0041] Example 3

[0042] Please refer to Figure 2 and Figure 3 The sealing connecting plate 2 is a flat plate structure, and both ends of the wave plate 1 are provided with plug-in grooves 101 corresponding to the sealing connecting plate 2.

[0043] It includes sealing plugs 7; multiple sealing plugs 7 are used to connect and seal the gap holes 102 at the connection between the sealing connecting plate 2 and the wave plate 1.

[0044] In this embodiment, the sealing connecting plates 2 at both ends of the corrugated plate 1 are not integral with the corrugated plate 1; the insertion slot 101 can be located at the center dividing line of the cross section of the corrugated plate 1. The sealing connecting plate 2 is a flat plate, with one end inserted into the insertion slot 101. The insertion slot 101 serves as a connection base, facilitating further welding or gluing of the corrugated plate 1 and the sealing connecting plates 2 at both ends, strengthening the connection and sealing the gap holes 102.

[0045] Alternatively, the sealing plug 7 may be directly selected to connect and seal the gap hole 102 .

[0046] In some embodiments, the cross-section of the wave plate 1 has a crest and a trough profile that are V-shaped or curved.

[0047] Compared with the heat dissipation fin plate, the wave plate 1 is easier to manufacture and has a lower cost because the wave plate 1 can be made from an ordinary flat plate with a single stamping die stroke to produce a wavy surface.

[0048] However, heat sink fin plates often require machine tools to plane and process rows of fins, which is energy-intensive and inefficient.

[0049] Moreover, the corrugated plate 1 as the plate body is more convenient to wipe off dust and clean.

[0050] Please refer to Figure 2 and Figure 3 The side of the corrugated plate 1 that is not connected to the sealing connecting plate 2 is a straight side.

[0051] If the edge outline of the corrugated plate 1 is projected as a rectangle when viewed from the front, both sides of the corrugated plate 1 are straight edges.

[0052] In this way, the straight side of the wave plate 1 is connected to the side wall of the inner cavity of the shell 4, which is more closely fitted, so that the first cavity 510 and the second cavity 520 are more interconnected.

[0053] Preferably, the length direction of the grooves on the wave plate 1 is the same as the exhaust airflow direction or the blowing airflow direction of the first cooling fan 3 .

[0054] The air duct formed in this way is more convenient for air flow to circulate quickly, taking away heat and avoiding heat accumulation.

[0055] Please refer to Figure 2 , including a second cooling fan 8, which is arranged in the chamber where the electronic components are located in the inner cavity of the electrical device shell. When the electrical device is provided with a rear cover plate 6, it is the first chamber 510 and is located at one end of the wave plate 1 or adjacent to the sealing connecting plate 2.

[0056] The second cooling fan 8 blows the air in the first chamber 510 to balance the temperature and heat, and the heat is more fully transferred to the corrugated plate 1 .

[0057] Please refer to Figure 2 , including a third cooling fan 9, the third cooling fan 9 is arranged in the chamber where the electronic components are located in the inner cavity of the electrical device shell. When the electrical device is provided with a rear cover plate 6, it is the first chamber 510, and is symmetrically distributed with the second cooling fan 8.

[0058] The third cooling fan 9 cooperates with the second cooling fan 8 to enhance the air flow circulation in the first chamber 510 .

[0059] In some embodiments, in order to accelerate and strengthen the flow of external air in the second chamber 520 , another fan cooperating with the first cooling fan 3 may be provided in the second chamber 520 .

[0060] Preferably, the length direction of the grooves on the wave plate 1 is the same as the exhaust airflow direction or the blowing airflow direction of the second cooling fan 8 and the third cooling fan 9 in the first chamber 510 .

[0061] Preferably, the first cooling fan 3, the second cooling fan 8, and the third cooling fan 9 are cross-flow impeller fans.

[0062] The present application also provides an advertising machine, including a heat dissipation structure as described above; also including a second cooling fan 8 and a third cooling fan 9; the outer edge of the partition plate 150 is connected to the side wall of the inner cavity of the shell 4 of the advertising machine, dividing the inner cavity of the shell 4 of the advertising machine into a first chamber 510 and a second chamber 520 that are not connected to each other; the back cover 6 of the advertising machine is provided with a vent; the first cooling fan 3 is located in the second chamber 520 and is arranged corresponding to the vent; a first spacer 12 is provided between the display module 10 of the advertising machine and the transparent protective layer 11 of the advertising machine; a second spacer 13 is provided between the display module 10 and the partition plate 150; the second cooling fan 8 and the third cooling fan 9 are respectively provided at both ends of the display module 10, corresponding to the first spacer 12 and the second spacer 13 to fan and drive air circulation.

[0063] The display module 10 of an advertising machine typically has one end surface for displaying images or videos, with the back surface housing various electronic components, such as the main control board and driver board. The display end surface of the display module 10 faces the transparent protective layer 11, with a first spacer 12 positioned between the display module 10 and the transparent protective layer 11.

[0064] The transparent protective layer 11 can be made of any of glass, tempered glass, and acrylic. The back side of the display screen of the display module 10 is relatively close to the corrugated plate 1 of the partition plate 150 .

[0065] By providing second and third cooling fans 8 and 9, corresponding to the air ducts in first and second compartments 12 and 13, respectively, air circulation within first chamber 510 is enhanced, allowing heat from the display screen to be easily transferred to corrugated plate 1 for dissipation. Furthermore, the layout of second and third cooling fans 8 and 9 is optimized to minimize the impact on the thickness of the advertising display.
