Description

Technical Field

[0001] This utility model relates to the field of display screen cabinet technology, specifically to a display screen cabinet with high-efficiency heat dissipation. Background Technology

[0002] LED displays are a new type of imaging electronic device made by arranging light-emitting diodes in sequence. Due to their high brightness, wide viewing angle, and long lifespan, they are widely used in products such as outdoor advertising screens. The LED display cabinet mainly serves to fix and protect the LED display, protecting the internal components from external environmental influences and preventing damage. The LED display cabinet fixes all the display components, such as unit boards and power supplies, inside the cabinet, making the connection of the entire display more convenient and simple. The LED display cabinet can also fix the frame structure of the entire display, making the display more convenient and stable during placement or installation.

[0003] As LED displays become more powerful and their applications become more widespread and complex, the heat generated during operation accumulates inside the cabinet. The cabinet typically relies on a single fan for heat dissipation, which is inefficient and ineffective, resulting in high internal temperatures and affecting the lifespan of the LED display. Therefore, improvements are urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a display screen enclosure with high-efficiency heat dissipation to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation display screen enclosure, comprising:

[0006] The main body of the cabinet has a display screen mounting frame on one side, a heat dissipation bracket fixed inside the main body of the cabinet, and a cooling fan installed on the outer wall of the main body of the cabinet away from the display screen mounting frame.

[0007] A water-cooled heat dissipation structure is provided on the surface of a heat dissipation bracket. The water-cooled heat dissipation structure includes a heat exchange tube assembly, an inlet pipe, an outlet pipe, and a storage tank. The heat exchange tube assembly is mounted on the surface of the heat dissipation bracket. The inlet pipe is fixed to one end of the heat exchange tube assembly, and the outlet pipe is fixed to the other end of the heat exchange tube assembly. The storage tank is mounted on the outer wall of the main body of the housing below the cooling fan. Semiconductor cooling chips are mounted on the surface of the heat dissipation bracket on one side of the water-cooled heat dissipation structure.

[0008] Preferably, the inner surface of the display screen mounting frame is provided with dovetail grooves, and a dovetail slider is provided on one side of the dovetail groove. The dovetail slider is slidably connected to the dovetail groove, which facilitates the adjustment of the position of the elastic clip.

[0009] Preferably, the display screen mounting frame is connected to the main body of the cabinet by bolts, which facilitates fixing the display screen mounting frame to the main body of the cabinet.

[0010] Preferably, the water-cooled heat dissipation structure further includes a first circulation pump, a heat sink, and a second circulation pump. The first circulation pump is installed on the outer wall of the main body of the tank on one side of the liquid storage tank. The input end of the first circulation pump is connected to the liquid storage tank, and the output end of the first circulation pump is connected to the inlet pipe. The second circulation pump is installed on the outer wall of the main body of the tank on the other side of the liquid storage tank. The input end of the second circulation pump is connected to the outlet pipe, and the output end of the second circulation pump is connected to the liquid storage tank, which facilitates the circulation of the coolant.

[0011] Preferably, the heat sinks are all fixed on the outer surface of the liquid storage tank to facilitate the heat dissipation of the coolant inside the tank.

[0012] Preferably, elastic clips are fixed on the outer wall of the dovetail slider on the side away from the dovetail groove, which facilitates the fixing of the LED display wire harness and makes the wiring neater.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the high-efficiency heat dissipation display cabinet is equipped with multiple heat dissipation structures, which have high heat dissipation efficiency and good heat dissipation effect, reduce the temperature inside the cabinet, and extend the service life of the LED display.

[0014] The system incorporates a heat dissipation bracket, heat exchanger assembly, inlet pipe, outlet pipe, first circulation pump, storage tank, heat sink, second circulation pump, thermoelectric cooler, and cooling fan. Since the heat exchanger assembly is mounted on the heat dissipation bracket, during LED display operation, the first circulation pump draws coolant from the storage tank and introduces it into the heat exchanger assembly through the inlet pipe. As the coolant flows within the heat exchanger assembly, it carries away heat from the main body of the cabinet. Simultaneously, the cooling fan accelerates the airflow within the main body of the cabinet, rapidly dissipating heat to the outside. The second circulation pump draws coolant out through the outlet pipe and returns it to the storage tank. The heat sink facilitates heat dissipation from the coolant inside the storage tank, allowing for reuse after cooling. Furthermore, since the thermoelectric cooler is mounted on one side of the heat exchanger assembly, with its cooling surface facing the LED display, it further dissipates heat from the LED display. This multi-layered heat dissipation structure within the cabinet ensures rapid and effective heat dissipation, reducing the internal temperature of the cabinet and extending the lifespan of the LED display.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 One embodiment of this utility model provides: a high-efficiency heat dissipation display screen housing, comprising:

[0023] The cabinet body 1 has a display screen mounting frame 2 on one side, a heat dissipation bracket 3 is fixed inside the cabinet body 1, and a heat dissipation fan 6 is installed on the outer wall of the cabinet body 1 on the side away from the display screen mounting frame 2.

[0024] The water-cooled heat dissipation structure 4 is set on the surface of the heat dissipation bracket 3. The water-cooled heat dissipation structure 4 includes a heat exchange tube assembly 401, an inlet pipe 402, an outlet pipe 403, and a storage tank 405. The heat exchange tube assembly 401 is installed on the surface of the heat dissipation bracket 3. The inlet pipe 402 is fixed to one end of the heat exchange tube assembly 401, and the outlet pipe 403 is fixed to the other end of the heat exchange tube assembly 401. The storage tank 405 is installed on the outer wall of the main body 1 of the box below the cooling fan 6. Semiconductor cooling chips 5 are installed on the surface of the heat dissipation bracket 3 on one side of the water-cooled heat dissipation structure 4.

[0025] The inner surface of the display mounting frame 2 is provided with dovetail grooves 7, and a dovetail slider 8 is provided on one side of the dovetail groove 7. The dovetail slider 8 is slidably connected to the dovetail groove 7, which facilitates the adjustment of the position of the elastic clip 9.

[0026] The display screen mounting frame 2 is connected to the cabinet body 1 by bolts, which makes it easy to fix the display screen mounting frame 2 to the cabinet body 1;

[0027] The water-cooled heat dissipation structure 4 also includes a first circulation pump 404, a heat sink 406, and a second circulation pump 407. The first circulation pump 404 is installed on the outer wall of the main body 1 of the housing on one side of the liquid storage tank 405. The input end of the first circulation pump 404 is connected to the liquid storage tank 405, and the output end of the first circulation pump 404 is connected to the inlet pipe 402. The second circulation pump 407 is installed on the outer wall of the main body 1 of the housing on the other side of the liquid storage tank 405. The input end of the second circulation pump 407 is connected to the outlet pipe 403, and the output end of the second circulation pump 407 is connected to the liquid storage tank 405, which facilitates the circulation of coolant.

[0028] The heat sinks 406 are all fixed on the outer surface of the liquid storage tank 405 to facilitate the heat dissipation of the coolant inside the liquid storage tank 405.

[0029] Elastic clips 9 are fixed on the outer wall of the dovetail slider 8 on the side away from the dovetail groove 7, which facilitates the fixing of the LED display wire harness and makes the wiring more neat.

[0030] In this embodiment, the following steps are taken: First, the display screen mounting frame 2 is fixed to the main body 1 of the housing with bolts. The LED display screen is installed inside the display screen mounting frame 2. Since the heat exchange tube assembly 401 is mounted on the heat dissipation bracket 3, when the LED display screen is working, the first circulation pump 404 draws coolant from the storage tank 405 and introduces it into the heat exchange tube assembly 401 through the inlet pipe 402. As the coolant flows inside the heat exchange tube assembly 401, it carries away the heat inside the main body 1. At the same time, the cooling fan 6 operates, which increases the airflow speed inside the main body 1, allowing the heat to be quickly dissipated to the outside. The second circulation pump 407 draws coolant out through the outlet pipe 403 and transports it back into the storage tank 405. The heat sink 406 facilitates the cooling of the storage tank 405. The liquid cooling system allows for heat dissipation and reuse after cooling. Furthermore, since the semiconductor cooling chip 5 is installed on one side of the heat exchange tube assembly 401, with its cooling surface facing the LED display screen, it can further dissipate the heat from the LED display screen, resulting in faster heat dissipation and better heat dissipation of the cabinet, reducing the internal temperature of the cabinet and extending the service life of the LED display screen. Secondly, since the inner surface of the display screen mounting frame 2 is provided with multiple sets of dovetail grooves 7, the dovetail slider 8 can slide along the dovetail grooves 7 and has a certain damping effect. The position of the dovetail slider 8 can be adjusted as needed. When wiring the LED display screen, the wire harness can be fixed by clamping it in the elastic clip 9, which facilitates neat wiring, prevents the wire harness from tangling, and facilitates subsequent inspection and maintenance.
