Description

A heat dissipation structure and an advertising machine Technical Field

[0001] This application relates to the field of advertising machine technology, specifically a heat dissipation structure and an advertising machine. Background Technology

[0002] Many devices, such as digital signage machines, projectors, and induction cookers, typically have built-in air-cooling systems with air inlets and outlets on their casings. This allows outside air to be drawn into the machine, flowing over components that generate significant heat during operation, such as the main control board and backlight panel, before being expelled through the outlets. However, even with filters at the air inlets, dust inevitably accumulates inside the machine over time. This not only causes dirt and grime but also affects the internal electrical environment, potentially shortening the device's lifespan and causing malfunctions.

[0003] Therefore, there is an urgent need for a new type of heat dissipation structure that can meet the heat dissipation requirements of the device and also achieve dust prevention, so as to avoid affecting the internal electronic components of the device.

[0004] Utility Model Content

[0005] This utility model addresses the above-mentioned problems by proposing a heat dissipation structure and an advertising machine, aiming to solve the technical problems in the background art.

[0006] To achieve the above objectives, this utility model provides a heat dissipation structure and an advertising machine, including a corrugated plate, a sealing connecting plate, and a first cooling fan; the corrugated plate and the sealing connecting plate are disposed in the inner cavity of the electrical device housing; there are two sealing connecting plates, which are respectively connected to both ends of the corrugated 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 electrical device housing, separating the electronic components of the inner cavity of the electrical device housing from the outside; the first cooling fan is used to drive air to flow on the surface of the partition plate.

[0007] Furthermore, the outer edge of the partition plate is connected to the inner wall of the electrical device's housing, dividing the inner cavity of the electrical device's housing into a first chamber and a second chamber that are not interconnected; the electronic components of the electrical device are located in the first chamber; the second chamber is formed by the partition plate, part of the side wall of the electrical device's housing, and the rear cover of the electrical device; the rear cover of the electrical device is provided with a ventilation opening; the first cooling fan is located in the second chamber.

[0008] Furthermore, the sealing connection plate is a flat plate structure, and the two ends of the corrugated plate are provided with insertion grooves corresponding to the sealing connection plate.

[0009] 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.

[0010] Furthermore, the cross-section of the wave plate has a V-shaped or curved profile for the crests and troughs.

[0011] Furthermore, the side of the corrugated plate that is not connected to the sealing connection plate is a straight edge.

[0012] Furthermore, the length direction of the groove on the wave plate is the same as the direction of the exhaust airflow or the blowing airflow of the first cooling fan in the second chamber.

[0013] Furthermore, it includes a second cooling fan, which is located in the cavity of the electronic components inside the housing of the electrical device, and is located at one end of the corrugated plate or adjacent to the sealing connection plate.

[0014] Furthermore, it includes a third cooling fan, which is located in the cavity of the electronic components inside the housing of the electrical device and is symmetrically distributed with the second cooling fan.

[0015] Furthermore, the length direction of the groove on the wave plate is the same as the direction of the exhaust airflow or the blowing airflow of the second and third cooling fans in the first chamber.

[0016] Furthermore, the first cooling fan, the second cooling fan, and the third cooling fan are cross-flow impeller fans.

[0017] This application also provides an advertising machine, including a heat dissipation structure as described above; it also includes a second cooling fan and a third cooling fan; the outer edge of the partition plate is connected to the inner wall of the advertising machine's housing cavity, dividing the inner cavity of the advertising machine's housing cavity into a first chamber and a second chamber that are not interconnected; the rear cover of the advertising machine is provided with a ventilation opening; the first cooling fan is located in the second chamber; a first interval area is provided between the display module of the advertising machine and the transparent protective layer of the advertising machine; a second interval area is provided between the display module and the partition plate; the second cooling fan and the third cooling fan are respectively located at both ends of the display module, corresponding to the first interval area and the second interval area to drive airflow circulation.

[0018] Compared with existing technologies, the heat dissipation structure and advertising machine provided by this utility model can transfer heat from the first chamber to the partition plate. Because the partition plate contains a corrugated plate, which has wavy folds compared to a regular flat plate, it has a larger surface area for the same perimeter, thus transferring more heat. The first cooling fan located in the second chamber draws outside air into the second chamber through an air intake vent. The air flows through the corrugated plate 1 with its wavy folds and is then blown out through an air outlet vent, thereby carrying away the heat generated by the corrugated plate and the first chamber during operation, achieving a cooling effect.

[0019] Because the outer edge of the partition plate is connected to the inner wall of the electrical device's housing, it divides the inner cavity of the electrical device into two non-communicating chambers: a first chamber and a second chamber. This prevents outside air from entering the first chamber and dust particles from contaminating the electronic components of the electrical device, thus avoiding dirt or malfunctions. At the same time, it also provides a certain degree of waterproofing to the first chamber, extending the service life of the equipment. Attached Figure Description

[0028] Referring to Figures 1, 3, and 4, this embodiment provides a heat dissipation structure and an advertising machine, including a corrugated plate 1, a sealing connecting plate 2, and a first cooling fan 3. The corrugated plate 1 and the sealing connecting plate 2 are disposed in the inner cavity of the electrical device housing. There are two sealing connecting plates 2, which are respectively connected to both ends of the corrugated 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 inner cavity side wall of the electrical device housing 4, separating the electronic components inside the electrical device housing from the outside. The first cooling fan 3 is used to drive air to flow on the surface of the partition plate 150.

[0029] In this embodiment, the electrical device housing may not have a back cover; the partition plate 150 directly serves as the back cover of the electrical device housing. The first cooling fan 3 can be located outside the electrical device housing and can be selected as a waterproof fan.

[0030] Electrical appliances can be the advertising machines mentioned below, or they can be projectors, induction cookers, computer mainframes, and other electrical equipment.

[0031] Referring to Figures 1-4, this embodiment provides a heat dissipation structure and an advertising machine, including a corrugated plate 1, a sealing connecting plate 2, and a first cooling fan 3. The corrugated plate 1 and the sealing connecting plate 2 are disposed in the inner cavity of the electrical device's housing. There are two sealing connecting plates 2, which are respectively connected to both ends of the corrugated 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 inner wall of the electrical device's housing 4, dividing the inner cavity of the electrical device's housing 4 into a first chamber 510 and a second chamber 520 that are not interconnected. 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, part of the side wall of the electrical device's housing, and the rear cover plate 6 of the electrical device. The rear cover plate 6 of the electrical device is provided with a ventilation opening (not shown). The first cooling fan 3 is located in the second chamber 520.

[0032] In some embodiments, the outer contour of the partition plate 150 can be modeled after the contour of the inner cavity sidewall of the housing 4 of the electrical device; the box or cabinet is generally a regular rectangle, but some boxes or cabinets are irregular shapes. In this case, the partition plate 150 corresponds to the inner contour and is also irregularly shaped, so that the outer edge abuts against the inner cavity sidewall of the housing 4, separating the first chamber 510 and the second chamber 520 into non-communicating sections.

[0033] In some embodiments, the first cooling fan 3 may be provided corresponding to the ventilation opening.

[0034] The ventilation opening consists of at least one air inlet and one air outlet. Depending on the direction of the fan blades of the first cooling fan 3, the corresponding ventilation opening is either an air inlet or an air outlet.

[0035] The ventilation opening is not limited to being located on the rear cover plate 6, but can also be located in other parts of the housing 4.

[0036] During operation, the heat from the first chamber 510 is transferred to the partition plate 150. Because the partition plate 150 contains a corrugated plate 1, which has wavy folds compared to a regular flat plate, it has a larger surface area for the same perimeter, thus transferring more heat. Meanwhile, the first cooling fan 3 located in the second chamber 520 draws outside air into the second chamber 520 through an air intake vent. The air flows over the corrugated plate 1 with its wavy folds, enhancing airflow and convection on the surface of the partition plate 150, and then is blown out through the exhaust vent, thereby carrying away the heat generated by the corrugated plate 1 and the first chamber 510 during operation, achieving a cooling effect.

[0037] Since the outer edge of the partition plate 150 is connected to the inner wall of the housing 4 of the electrical device, the inner cavity of the housing 4 of the electrical device is divided into a first chamber 510 and a second chamber 520 that are not connected to each other. Therefore, outside air will not enter the first chamber 510, and dust particles will not be mixed in with the electronic components of the electrical device, causing dirt or malfunction. At the same time, it can also provide a certain waterproof effect for the first chamber 510 and improve the service life of the equipment.

[0038] Example 1

[0039] The sealing connection plates 2 at both ends of the corrugated plate 1 are integral with the corrugated plate 1 and belong to the same plate. The sealing connection plate 2 has a corrugated connection structure with the corrugated plate 1, which gradually transitions to a straight structure. The straight section of the sealing connection plate 2 is connected to the inner cavity side wall of the electrical device housing 4, thereby separating the first chamber 510 and the second chamber 520 into non-communicating sections.

[0040] Example 2

[0041] The sealing connecting plates 2 at both ends of the corrugated plate 1 are not integral structures with the corrugated plate 1, but are three independent entities. The sealing connecting plates 2 can be connected to the corrugated plate 1 by welding, gluing, screw connection, etc. At one end of the sealing connecting plate 2 connected to the corrugated plate 1, there is a corrugated connection structure with the corrugated plate 1, and at the other end, it gradually transitions to a straight structure.

[0042] Example 3

[0043] Please refer to Figures 2 and 3. The sealing connection plate 2 is a flat plate structure, and the two ends of the corrugated plate 1 are provided with insertion grooves 101 corresponding to the sealing connection plate 2.

[0044] Includes sealing plugs 7; a plurality of the sealing plugs 7 are used to connect and block the gap holes 102 at the connection between the sealing connecting plate 2 and the corrugated plate 1.

[0045] 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 position of the insertion groove 101 can be the center dividing line of the cross-section of the corrugated plate 1. The sealing connecting plate 2 is a flat plate structure, with one end inserted into the insertion groove 101, so that the insertion groove 101 serves as a connection base, facilitating further welding or glue connection between the corrugated plate 1 and the sealing connecting plates 2 at both ends, strengthening the connection, and sealing the gap hole 102.

[0046] Alternatively, the sealing plug 7 can be directly used to connect and seal the gap hole 102.

[0047] In some embodiments, the cross-section of the wave plate 1 has a V-shaped or curved profile for the crests and troughs.

[0048] Compared to heat dissipation fin plates, wave plate 1 is easier to process and manufacture, and its cost is lower. This is because wave plate 1 can be made from ordinary flat plates with a single stamping stroke of a stamping die to produce a wave-shaped surface.

[0049] Heat sink fins often require machine tools to cut and process rows of fins, which is energy-intensive and inefficient.

[0050] Moreover, the wave plate 1, as the plate body, makes it easier to wipe away dust and clean.

[0051] Please refer to Figures 2 and 3. The side of the corrugated plate 1 that is not connected to the sealing connecting plate 2 is a straight edge.

[0052] When the edge contour projection of the wave plate 1 is rectangular from the frontal view, the two sides of the wave plate 1 are straight edges.

[0053] In this way, the straight side of the wave plate 1 is connected to the inner wall of the shell 4, making them fit better and increasing the degree of non-communication between the first chamber 510 and the second chamber 520.

[0054] Preferably, the length direction of the groove on the wave plate 1 is the same as the direction of the exhaust airflow or the blowing airflow of the first cooling fan 3.

[0055] This type of airflow channel facilitates rapid airflow, carrying away heat and preventing heat buildup.

[0056] Please refer to Figure 2, which includes a second cooling fan 8. The second cooling fan 8 is located in the cavity of the electronic components inside the housing of the electrical device. When the electrical device is equipped with a rear cover plate 6, it is the first cavity 510, and is located at one end of the corrugated plate 1 or adjacent to the sealing connection plate 2.

[0057] The second cooling fan 8 blows air into the first chamber 510, which facilitates temperature and heat balance and allows heat to be transferred to the wave plate 1 more fully.

[0058] Please refer to Figure 2, which includes a third cooling fan 9. The third cooling fan 9 is located in the cavity of the electronic components inside the housing of the electrical device. When the electrical device is equipped with a rear cover plate 6, it is the first cavity 510, and is symmetrically distributed with the second cooling fan 8.

[0059] The third cooling fan 9 works in conjunction with the second cooling fan 8 to enhance airflow circulation within the first chamber 510.

[0060] In some embodiments, in order to accelerate and enhance the flow of outside air in the second chamber 520, other fans that cooperate with the first cooling fan 3 may be added to the second chamber 520.

[0061] Preferably, the length direction of the groove on the wave plate 1 is the same as the direction of the exhaust airflow or the blowing airflow of the second cooling fan 8 and the third cooling fan 9 in the first chamber 510.

[0062] Preferably, the first cooling fan 3, the second cooling fan 8, and the third cooling fan 9 are cross-flow impeller fans.

[0063] This application also provides an advertising machine, including a heat dissipation structure as described above; it also includes a second cooling fan 8 and a third cooling fan 9; the outer edge of the partition plate 150 is connected to the inner cavity side wall of the advertising machine housing 4, dividing the inner cavity of the advertising machine housing 4 into a first chamber 510 and a second chamber 520 that are not interconnected; the rear cover plate 6 of the advertising machine is provided with a ventilation opening; the first cooling fan 3 is located in the second chamber 520 and is arranged corresponding to the ventilation opening; a first interval area 12 is provided between the display module 10 of the advertising machine and the transparent protective layer 11 of the advertising machine; a second interval area 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 located at both ends of the display module 10, and drive airflow circulation corresponding to the first interval area 12 and the second interval area 13.

[0064] The display module 10 of the advertising machine is generally a display screen with one end face used to display images or videos, while the back of the display screen contains various electronic components, such as the main control board and driver board. The display screen end face of the display module 10 faces the transparent protective layer 11, and a first gap area 12 is provided between the display module 10 and the transparent protective layer 11.

[0065] The transparent protective layer 11 can be any of glass, tempered glass, or acrylic sheet. The back of the display screen of the display module 10 is relatively close to the corrugated plate 1 of the partition plate 150.

[0066] By setting up a second cooling fan 8 and a third cooling fan 9, corresponding to the air ducts in the first interval zone 12 and the second interval zone 13 respectively, the airflow circulation within the first chamber 510 is enhanced, allowing heat from the display screen side to be easily transferred to the corrugated plate 1 for dissipation. Furthermore, the layout of the second cooling fan 8 and the third cooling fan 9 is reasonable, avoiding any impact on the thickness of the advertising machine.
