Description

Technical Field

[0001] The utility model relates to the field of LED displays, in particular to a heat dissipation structure of an LED display. Background Art

[0002] LED display is a display screen that controls the display mode of semiconductor light emitting diodes to display various information such as text, graphics, images, animations, quotes, videos, and recording signals. When the LED display is working, a lot of heat will be generated inside. If the heat is not dissipated in time, it will cause the display to malfunction. Therefore, it is necessary to set up a heat dissipation structure to dissipate the heat of the display.

[0003] The existing LED display heat dissipation structure generally dissipates heat through air cooling or water cooling. Air cooling uses a fan to blow air to the LED display to dissipate heat, while water cooling sends condensed water into a cooling pipe to absorb heat by flowing inside the cooling pipe, thereby achieving the purpose of dissipating heat for the LED display. However, after the condensed water absorbs heat for a long time, the temperature of the condensed water will increase. In order to prevent the condensed water from continuing to cool the LED display after the temperature has increased, the condensed water needs to be replaced so that the replaced condensed water can continue to absorb the heat generated by the operation of the LED display. However, since the condensed water is replaced frequently and the replacement process is more troublesome, the heat dissipation effect of the LED display is affected. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a heat dissipation structure for an LED display to solve the technical problem that condensed water needs to be replaced frequently, thereby affecting the heat dissipation of the LED display.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation structure of an LED display, comprising a shell, a radiator is provided on the back of the shell, a water storage chamber, a cooling chamber and an exchange chamber are respectively provided inside the radiator, a cooling component is provided inside the exchange chamber, and the cooling component comprises a water guide hopper provided above the exchange chamber, a dispersion plate provided below the exchange chamber, a protective cover installed on one side of the radiator and a reflux pipe connected between the exchange chamber and the water storage chamber, a one-way valve is installed at one end of the reflux pipe, a water guide pipe is connected to the bottom of the water guide hopper, and a semiconductor refrigeration plate is provided inside the protective cover.

[0006] By adopting the above technical solution, when the condensed water after absorbing heat flows into the water pipe, the setting of the water pipe can prolong the flow time of the condensed water inside the exchange chamber, so that the semiconductor refrigeration plate can cool the condensed water.

[0007] Furthermore, a cooling pipe is installed inside the cooling cavity, and a water outlet end of the cooling pipe is connected to a water outlet pipe extending into the interior of the exchange cavity.

[0008] By adopting the above technical solution, after the condensed water flows into the interior of the cooling pipe through the water pipe, the condensed water will flow inside the cooling pipe, thereby cooling the display.

[0009] Furthermore, a water pump is installed inside the water storage chamber, a water inlet end of the water pump is connected to a water inlet pipe, and a water delivery pipe is connected between a water outlet end of the water pump and a water inlet end of the cooling pipe.

[0010] By adopting the above technical solution, when the LED display needs to be cooled, the water pump can be started. The water pump can extract condensed water through the water inlet pipe, so that the condensed water flows into the water supply pipe.

[0011] Furthermore, a water guide plate is installed on one side of the exchange chamber, and one side of the water guide plate is inclined downward along the direction of the semiconductor refrigeration plate.

[0012] By adopting the above technical solution, part of the water will flow onto the water guide plate after being dispersed by the dispersion plate, and then flow toward the semiconductor refrigeration plate through the water guide plate.

[0013] Furthermore, a water inlet is provided on one side of the top of the radiator, and a sealing plug is provided inside the water inlet.

[0014] By adopting the above technical solution, the sealing plug can block the water inlet, preventing the water storage chamber from communicating with the outside through the water inlet, thereby preventing cold air from being discharged through the water inlet.

[0015] Furthermore, threads are provided on the inner wall of the water inlet and on the lower part of the outer wall of the sealing plug, and the sealing plug is threadedly connected to the water inlet.

[0016] By adopting the above technical solution, when condensed water needs to be added into the water storage chamber, the user can rotate the sealing plug and unscrew the sealing plug from the water inlet, and then the condensed water can be added into the water storage chamber.

[0017] Furthermore, the water guide pipe is in a snake shape, and the water guide bucket is located directly below the water outlet pipe.

[0018] By adopting the above technical solution, after water flows out of the water outlet pipe, the water will flow onto the water guide bucket, and continue to flow downward and flow into the inside of the water guide pipe.

[0019] Furthermore, the dispersion plate is located directly below the water outlet of the water pipe, and the dispersion plate is in the shape of an isosceles triangle.

[0020] By adopting the above technical solution, after the water flows out through the water guide pipe, the water will impact the dispersion plate, causing the water to flow to both sides, so that the water can flow in a dispersed manner.

[0021] Furthermore, the cooling pipe is in a snake shape, and a display body is installed inside the shell.

[0022] By adopting the above technical solution, the condensed water can flow into the cooling pipe to dissipate the heat of the display body.

[0023] In summary, the utility model mainly has the following beneficial effects:

[0024] The utility model is provided with a cooling component. When the condensed water after absorbing heat flows into the exchange chamber through the water outlet pipe, the condensed water will flow into the water guide pipe through the water guide bucket. The provision of the water guide pipe can prolong the flow time of the condensed water in the exchange chamber. After the water flows out of the water guide pipe, the water will impact the dispersion plate, causing the water to flow to both sides so as to disperse the water flow. The water flowing onto the water guide plate will flow in the direction close to the semiconductor refrigeration plate, thereby facilitating the semiconductor refrigeration plate to cool the water in the exchange chamber. The cooled water will flow back to the water storage chamber through the reflux pipe and the one-way valve for recycling. In this way, the flow time of the water in the exchange chamber can be prolonged, thereby improving the cooling effect of the semiconductor refrigeration plate on the water. At the same time, there is no need to replace the condensed water, so that the condensed water can continuously cool the display. Moreover, this process can prevent the condensed water after absorbing heat from flowing back to the water storage chamber for recycling without being cooled, thereby improving the subsequent cooling effect on the display.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0031] The following describes an embodiment of the utility model based on its overall structure.

[0032] Embodiment 1:

[0033] A heat dissipation structure of an LED display, such as Figure 1-Figure 4 As shown, it includes a shell 1, a radiator 2 is provided on the back of the shell 1, and a water storage chamber 7, a cooling chamber 8 and an exchange chamber 10 are respectively provided inside the radiator 2. A cooling component 9 is provided inside the exchange chamber 10, and a water pump 6 is installed inside the water storage chamber 7. The water inlet end of the water pump 6 is connected with a water inlet pipe, and a water pipe 5 is connected between the water outlet end of the water pump 6 and the water inlet end of the cooling pipe 3. When the LED display needs to be cooled, the water pump 6 can be started. The water pump 6 can extract condensed water through the water inlet pipe so that the condensed water flows into the water pipe 5. A cooling pipe 3 is installed inside the cooling chamber 8, and the water outlet end of the cooling pipe 3 is connected with a water outlet pipe 4 extending to the inside of the exchange chamber 10. After the condensed water flows into the cooling pipe 3 through the water pipe 5, the condensed water will flow inside the cooling pipe 3, so that the display can be cooled. The cooling pipe 3 is in a snake shape. A display body 13 is installed inside the shell 1, so that after the condensed water flows into the cooling pipe 3, the display body 13 can be cooled.

[0034] Specifically, the cooling component 9 includes a water guide 901 arranged at the upper part of the exchange chamber 10, a dispersion plate 905 arranged at the lower part of the exchange chamber 10, a protective cover 904 installed on one side of the radiator 2, and a return pipe 907 connected between the exchange chamber 10 and the water storage chamber 7. The dispersion plate 905 is located directly below the water outlet of the water pipe 902. The dispersion plate 905 is shaped like an isosceles triangle, so that after the water flows out through the water pipe 902, the water will impact the dispersion plate 905, causing the water to flow to both sides, so that the water can flow in a dispersed manner.

[0035] Specifically, a one-way valve 908 is installed at one end of the reflux pipe 907. The setting of the one-way valve 908 allows the water inside the exchange chamber 10 to flow back into the water storage chamber 7, while the water in the water storage chamber 7 cannot flow into the exchange chamber 10 through the one-way valve 908 and the reflux pipe 907. The bottom of the water guide bucket 901 is connected to a water guide pipe 902. When water flows out of the water outlet pipe 4, the water will flow to the water guide bucket 901 and continue to flow downward and flow into the water guide pipe 902. The water guide pipe 902 is snake-shaped. The water guide bucket 901 is located directly below the water outlet pipe 4. A semiconductor cooling plate 903 is provided inside the protective cover 904. When the condensed water after absorbing heat flows into the water guide pipe 902, the setting of the water guide pipe 902 can extend the flow time of the condensed water in the exchange chamber 10, so that the semiconductor cooling plate 903 can cool the condensed water.

[0036] Embodiment 2:

[0037] On the basis of the above-mentioned first embodiment, in order to make the water dispersed by the impact dispersion plate 905 flow toward the direction close to the semiconductor cooling plate 903, the following structure is set.

[0038] See also Figure 2-Figure 4 A water guide plate 906 is installed on one side of the exchange chamber 10. One side of the water guide plate 906 is tilted downward in the direction of the semiconductor refrigeration plate 903. After part of the water is dispersed by the dispersion plate 905, it will flow onto the water guide plate 906 and then flow toward the semiconductor refrigeration plate 903 through the water guide plate 906.

[0039] Embodiment three:

[0040] On the basis of the above-mentioned first embodiment, since it is necessary to add condensed water into the water storage chamber 7 to facilitate the subsequent condensed water to flow into the cooling tube 3 to cool the display, the following structure is set.

[0041] See also Figure 1-Figure 3 A water inlet 11 is provided on one side of the top of the radiator 2, and a sealing plug 12 is provided inside the water inlet 11. The sealing plug 12 can block the water inlet 11 to prevent the water storage chamber 7 from communicating with the outside through the water inlet 11, thereby preventing cold air from being discharged through the water inlet 11. Threads are provided on the inner wall of the water inlet 11 and the lower part of the outer wall of the sealing plug 12. The sealing plug 12 is threadedly connected to the water inlet 11. When condensed water needs to be added to the water storage chamber 7, the user can rotate the sealing plug 12 and unscrew the sealing plug 12 from the water inlet 11. At this time, condensed water can be added to the inside of the water storage chamber 7.

[0042] The working principle of the utility model is as follows: first, the user can rotate the sealing plug 12 to unscrew the sealing plug 12 from the water inlet 11, and then add the condensed water into the water storage chamber 7 through the water inlet 11. After the addition is completed, the sealing plug 12 is rotated back to the water inlet 11 to seal the water inlet 11. When the LED display needs to be cooled, the water pump 6 and the semiconductor refrigeration sheet 903 can be started. The water pump 6 can extract the condensed water through the water inlet pipe, so that the condensed water flows into the water delivery pipe 5. After the condensed water flows into the cooling pipe 3 through the water delivery pipe 5, the condensed water will flow inside the cooling pipe 3, so that the display can be cooled.

[0043] After absorbing heat, the condensed water will flow into the water guide 901 through the water outlet pipe 4. The setting of the water guide pipe 902 can prolong the flow time of the condensed water in the exchange chamber 10. After the water flows out of the water guide pipe 902, the water will impact the dispersion plate 905, causing the water to flow to both sides so as to disperse the water flow. The water flowing onto the water guide plate 906 will flow toward the direction close to the semiconductor refrigeration plate 903, thereby facilitating the semiconductor refrigeration plate 903 to cool the water in the exchange chamber 10. The cooled water will flow back to the water storage chamber 7 through the reflux pipe 907 and the one-way valve 908 for recycling.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
