Description

Technical Field

[0001] The utility model relates to the technical field of display screen heat dissipation, in particular to a heat dissipation type LED display screen. Background Art

[0002] Led display is a kind of display widely used in daily life, integrating microelectronics technology, computer technology, and information processing. It is widely used in commercial advertising and information dissemination with its advantages of bright colors, wide dynamic range, low power consumption, long life, impact resistance, stable and reliable operation, etc., and can meet the needs of different environments. At present, most of the liquid crystal display screens are produced, and the display screen body is installed with the whole machine shell. After the signal and power are connected, the display screen body outputs image data. At the same time, the cooling device on the whole machine shell dissipates heat and cools the display screen body, so that the display screen body can stably output image data.

[0003] This type of LED display screen includes a display screen body and a shell, wherein the front side of the shell is fixedly connected to the display screen body, the back side of the bottom plate is fixedly connected to a fixing block, a threaded hole is opened on one side of the fixing block, a fan is connected to one side of the outer surface of the shell by bolts, and a filter is fixedly connected to the outer side of the fan and the shell by bolts. This LED display screen heat dissipation device is provided with a shell, a fixing block, bolts, a filter, and a fan. When in use, the fan is first placed in the vent, and air passes through the vent during the heat dissipation process. The heat sink built into the host is mostly in the shape of long strips, and the contact area between the heat sink surface and the air is small, resulting in poor heat dissipation effect. In addition, the fan of the current heat dissipation device is installed close to the heat sink of the host, and the small spacing causes slow air circulation and poor cooling efficiency. At the same time, the fan and the filter are fixed to the shell with bolts. When the fan and the filter need to be cleaned and replaced, the bolts must be removed repeatedly, which increases the workload.

[0004] Therefore, it is necessary to provide a new heat dissipation type LED display screen to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a heat dissipation type LED display screen.

[0006] The utility model provides a heat dissipation type LED display screen, comprising a screen host and a protective shell fixed on the rear side thereof, and a heat dissipation cavity is formed between the screen host and the protective shell, two rows of heat dissipation fins arranged horizontally extend from the body of the screen host on the back side, and the upper and lower surfaces of the heat dissipation fins are in an arc shape bent downward, an air inlet is penetrated on one side above the protective shell, and an air outlet is penetrated on the other side below the protective shell, and slide grooves are respectively arranged inside the air inlet and the air outlet, an air inlet fan and a first filter are clamped in the air inlet slide groove, and an air outlet fan and a second filter are clamped in the air outlet slide groove, and the heat dissipation cavity of the heat dissipation shell is arranged in an arc shape away from the opposite ends of the air inlet and the air outlet.

[0007] Furthermore, the heat dissipation fins are arranged in multiple rows and extend into the interior of the protective shell.

[0008] Furthermore, bolt holes are opened at four corners of the protective shell, bolts are arranged in the bolt holes, and the protective shell is fixedly connected to the screen host by bolts.

[0009] Furthermore, the air inlet chute includes an upper chute and a lower chute, and the upper chute and the lower chute are opened vertically to the screen host. A filter No. 1 is placed in horizontal contact with the upper chute, and an air intake fan is placed in horizontal contact with the lower chute.

[0010] Furthermore, the chute, the air outlet fan and the second filter at the air outlet are arranged in a centrally symmetrical manner with respect to the air inlet.

[0011] Furthermore, the lower slide groove is provided with a card slot arranged in a vertical direction on a side away from the screen host.

[0012] Compared with the related art, the heat dissipation type LED display screen provided by the utility model has the following beneficial effects:

[0013] 1. The heat sink fins are arranged horizontally and are arc-shaped on the upper and lower sides, which increases the contact area between the gaps between the heat sink fins and the air, and the heat dissipation effect is better than that of traditional heat sinks.

[0014] 2. When the host is started, the motor will drive the air intake fan and the air outlet fan to rotate. When the air intake fan rotates, it drives the external air flow into the heat dissipation cavity. At the same time, the air outlet fan is also running and drawing air outward. The high-temperature air goes along the gap between the heat dissipation fins to the heat dissipation cavity above the air outlet fan, and is discharged out of the protective shell through the air outlet fan and the No. 2 filter in turn. The entire heat dissipation process only uses the air intake fan and the air outlet fan, and there is a lot of space in the heat dissipation cavity for air to enter, which not only saves costs, but also has higher air entry efficiency and better heat dissipation effect of the device.

[0015] 3. When replacement is required, first lift the No. 1 filter upwards. If it cannot be lifted, pull it out horizontally. Then pull the fan out horizontally from the lower slide. The removal process is convenient and quick, and replacement is easy. The setting of the upper slide and slot can effectively prevent the No. 1 filter and the intake fan from sliding off, ensuring the complete performance of the device.

[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 , Figure 1 This is a schematic diagram of the overall structure of the heat dissipation type LED display screen provided by the utility model; Figure 2 This is a schematic diagram of the back structure of the heat dissipation type LED display screen provided by the utility model; Figure 3 A schematic diagram of the explosion structure provided by the utility model; Figure 4 for Figure 3 A is a partial enlarged schematic diagram shown; Figure 5 A cross-sectional schematic diagram of the protective shell.

[0024] In the specific implementation process, Figures 1 to 5As shown, a heat dissipation type LED display screen includes a screen host 1 and a protective shell 2 fixed to the rear side thereof, and a heat dissipation cavity 3 is formed between the screen host 1 and the protective shell 2. Two rows of heat dissipation fins 4 arranged horizontally extend from the body of the screen host 1 on the back side. The upper and lower surfaces of the heat dissipation fins 4 are in an arc shape bent downward. An air inlet 5 is penetrated through one side of the upper part of the protective shell 2, and an air outlet 6 is penetrated through the other side of the lower part of the protective shell 2. Slide grooves are respectively arranged inside the air inlet 5 and the air outlet 6. An air inlet fan 7 and a first filter 8 are clamped in the slide groove of the air inlet 5, and an air outlet fan 9 and a second filter 10 are clamped in the slide groove of the air outlet 6. The heat dissipation cavity 3 of the heat dissipation shell is arranged in an arc shape away from the opposite end of the air inlet 5 and the air outlet 6;

[0025] Specifically, the main engine starts the motor intake fan 7 to drive the external air flow into the heat dissipation cavity 3. The arc-shaped shell below the protective shell 2 has a guiding effect, and the air flows horizontally toward the heat dissipation fins 4 and takes away the heat released by the heat dissipation fins 4. The upper and lower surfaces of the heat dissipation fins 4 are arc-shaped, so that the contact area between the gaps between the heat dissipation fins 4 and the air becomes larger, and the heat dissipation effect is better than that of the traditional heat sink. The exhaust fan 9 operates to draw air outward, and the high-temperature air is discharged out of the protective shell 2 through the exhaust fan 9 and the second filter 10 in turn. The entire heat dissipation process only uses the intake fan 7 and the exhaust fan 9, and there is a large space in the heat dissipation cavity 3 for air to enter, which not only saves costs, but also has higher air entry efficiency and better heat dissipation effect of the device.

[0026] The heat dissipation fins 4 are arranged in multiple rows and extend into the interior of the protective shell 2. Bolt holes are opened at the four corners of the protective shell 2. Bolts 14 are arranged in the bolt holes. The protective shell 2 is fixedly connected to the screen host 1 by the bolts 14. The air inlet 5 slide groove includes an upper slide groove 11 and a lower slide groove 12. The upper slide groove 11 and the lower slide groove 12 are opened vertically to the screen host 1. The upper slide groove 11 is horizontally contacted with a No. 1 filter 8, and the lower slide groove 12 is horizontally contacted with an intake fan 7. The slide groove at the air outlet 6, the air outlet fan 9 and the No. 2 filter 10 are centrally symmetrically arranged with the air inlet 5.

[0027] It should be noted that the operation of the air inlet fan 7 and the air outlet fan 9 will inevitably bring in dust in the air, so the filter and fan need to be cleanable and removable. The double-layer slide groove and card slot 13 opened at the air outlet 6 and the air inlet 5 are for facilitating the removal and placement of the fan and filter.

[0028] The lower slide 12 is provided with a card slot 13 arranged in a vertical direction on one side away from the screen host 1;

[0029] It should be noted that when the filter and fan at the air inlet 5 need to be replaced, first lift the No. 1 filter 8 upwards, and then pull it out horizontally when it cannot be lifted, and then pull the fan out horizontally from the lower slide 12. The removal process is convenient and fast, and replacement is easy. The setting of the upper slide 11 and the slot 13 can effectively prevent the No. 1 filter 8 and the air intake fan 7 from sliding off, thereby ensuring the complete performance of the device.

[0030] The working principle provided by the utility model is as follows: when the utility model is implemented, the main engine starts the motor to drive the air inlet fan 7 and the air outlet fan 9 to rotate, driving the external air flow into the heat dissipation cavity 3, protecting the guiding effect of the arc-shaped shell below the shell 2, and the air flows horizontally toward the heat dissipation fins 4, and takes away the heat released by the heat dissipation fins 4. The heat dissipation fins 4 are arranged horizontally and the upper and lower surfaces are arc-shaped, so that the contact area between the gaps between the heat dissipation fins 4 and the air becomes larger, and the heat dissipation effect is better than that of the traditional heat sink. The air outlet fan 9 operates to draw air outward, and the high-temperature air passes through the air outlet fan 9 and the second filter 10 row in turn. Outside the protective shell 2, the entire heat dissipation process only uses the air intake fan 7 and the air outlet fan 9, and there is a large amount of space in the heat dissipation cavity 3 for air to enter, which not only saves costs, but also increases the air entry efficiency and the heat dissipation effect of the device. The double-layer slide grooves and card slots 13 opened at the air outlet 6 and the air inlet 5 are for easy replacement. First, lift the No. 1 filter 8 upward, and then pull it out horizontally when it cannot be lifted. Then, pull the fan out horizontally from the lower slide groove 12. The taking process is convenient and easy, and the setting of the upper slide groove 11 and the card slot 13 can effectively prevent the No. 1 filter 8 and the air intake fan 7 from sliding off, thereby ensuring the complete performance of the device.
