[0031] The utility model provides a heat dissipation structure for a power supply of an LED display screen, wherein a baffle is arranged between an air inlet and an air outlet, wherein one end of the baffle is connected to a power supply housing, and a vent is formed between the other end and the power supply housing, so that a U-shaped air duct is formed inside the power supply housing, wherein one end of the U-shaped air duct is connected to the air inlet, and the other end is connected to the air outlet, and a fan is arranged on the U-shaped air duct, so that heat dissipation inside the power supply of the LED display screen can be achieved through air inlet and outlet on one side of the power supply housing, wherein the structure of the U-shaped air duct can better achieve heat dissipation of the power supply housing as a whole. Example

[0032] The utility model provides a LED display screen power supply heat dissipation structure, such as Figures 1 to 3 As shown, it includes a power supply shell 1, wherein the power supply shell 1 includes an air inlet 11 and an air outlet 12, the air inlet 11 and the air outlet 12 are arranged on the same side of the power supply shell 1, and a baffle plate 13 is arranged inside the power supply shell 1, and the baffle plate 13 is arranged between the air inlet 11 and the air outlet 12; one end of the baffle plate 13 is connected to the power supply shell 1, and a vent 14 is formed between the other end and the power supply shell 1; the baffle plate 13 forms a U-shaped air duct 15 inside the power supply shell 1, one end of the U-shaped air duct 15 is connected to the air inlet 11, and the other end is connected to the air outlet 12; a fan 16 is arranged on the U-shaped air duct 15, and the fan 16 is used to suck gas into the power supply shell 1 and / or to discharge gas from the power supply shell 1.

[0033] In this way, the baffle plate 13 forms a U-shaped air duct 15 inside the power supply housing 1. One end of the U-shaped air duct 15 is connected to the air inlet 11, and the other end is connected to the air outlet 12. Through this structure, it can be ensured that the air forms a cycle inside the power supply housing 1, so as to effectively take the heat out of the inside of the power supply. One or more fans 16 are installed on the U-shaped air duct 15. The fan 16 can adjust the speed as needed to control the flow speed of the air inside the power supply housing 1. The fan 16 can be used to draw external cold air into the power supply housing 1, and can also be used to discharge hot air from the inside of the power supply housing 1. The air inlet 11 and the air outlet 12 can be additionally provided with dustproof and waterproof structures to ensure that the inside of the power supply housing 1 will not be corroded by dust and rain in an outdoor environment. At the same time, the size and position of the air inlet 11 and the air outlet 12 are also carefully designed to ensure the smoothness and efficiency of air flow.

[0034] An exemplary description of one possible working principle of the LED display power supply heat dissipation structure provided by the utility model is given: when the LED display power supply starts working, the fan 16 starts to run. External cold air enters the power supply housing 1 through the air inlet 11, and is heated by the heat inside the power supply when passing through the U-shaped air duct 15. Then, the hot air is discharged from the power supply housing 1 through the air outlet 12. In this process, the role of the fan 16 can be to increase the air flow speed and improve the heat dissipation efficiency. Through the cooperation of the U-shaped air duct 15 and the fan 16, efficient air flow and heat exchange can be achieved, thereby ensuring that the LED display power supply can still maintain good heat dissipation performance when running under high load. The fan 16 can adjust the speed as needed to achieve energy saving and consumption reduction. At the same time, due to the high heat dissipation efficiency, the service life of the LED display power supply can be extended and the maintenance cost can be reduced. The heat dissipation structure is suitable for LED display power supplies in various environments and application scenarios. Especially in outdoor environments, its dustproof and waterproof design can ensure that the inside of the power supply housing 1 is not affected by the external environment.

[0035] like Figure 1 and Figure 2 As shown, more specifically, the fan 16 may be arranged at the air inlet 11 and / or the air outlet 12 and / or the vent 14. That is, one or more fans 16 may be arranged at any position in the air inlet 11, the air outlet 12, the vent 14 or the U-shaped air duct 15. Among them, the heat dissipation efficiency of the fan 16 arranged at the air outlet 12 may be relatively high, the fan 16 arranged at the air inlet 11 may make the air volume entering the power supply housing 1 relatively large, and the fan 16 arranged at the vent 14 may cooperate with the fan 16 arranged at other positions in the U-shaped air duct 15 to increase the overall ventilation volume, thereby improving the heat dissipation effect. In this way, the fan 16 is arranged at any position of the air inlet 11, the air outlet 12, the vent 14 or the U-shaped air duct 15, and can be flexibly adjusted according to actual conditions to achieve an efficient heat dissipation effect. When the fan 16 is arranged at the air inlet 11, the air volume entering the power supply housing 1 can be increased, thereby accelerating the convection and exchange of internal heat. The fan 16 is arranged at the air outlet 12, which can more effectively discharge the hot air inside the power supply and improve the heat dissipation efficiency. The fan 16 is arranged at the vent 14, which can cooperate with the fan 16 arranged at other positions of the U-shaped air duct 15 to improve the overall ventilation volume and heat dissipation effect.

[0036] like Figure 1 and Figure 2As shown, more specifically, the air outlet 12 may be arranged above the air inlet 11. In this way, the gas enters the power supply housing 1 from the air inlet 11 below the air outlet 12, and is discharged from the air outlet 12 above the air inlet 11 after passing through the U-shaped air duct 15. The density of the heated gas decreases and moves upward. The air outlet 12 is arranged above the air inlet 11 so that the heated gas can be discharged faster, which can improve the heat dissipation efficiency. The air outlet 12 is located above the air inlet 11. When the fan 16 is working, the external cold air enters the power supply housing 1 from the air inlet 11, and is heated and rises after passing through the heat source such as the power module, circuit board, etc. in the U-shaped air duct 15. Since the hot air has a low density, it will naturally rise and be discharged from the air outlet 12 located above. The air outlet 12 is located above the air inlet 11, and the natural phenomenon of hot air rising is used to discharge the heated gas faster, thereby improving the heat dissipation efficiency.

[0037] like Figure 1 and Figure 2 As shown, an LED display power supply heat dissipation structure provided by an embodiment of the utility model further includes a power supply component 17, and the power supply component 17 is arranged on the U-shaped air duct 15. More specifically, the power supply component 17 is arranged in the middle of the U-shaped air duct 15, so that the wind in the U-shaped air duct 15 can pass through the power supply component 17 from all sides, increasing the contact area between the gas and the power supply component 17, thereby improving the heat dissipation effect of the power supply component 17.

[0038] like Figure 1 and Figure 2 As shown, the power supply 17 includes a fin 171, and the fin 171 is at least arranged on one surface of the power supply 17. More specifically, the power supply 17 includes a plurality of fins 171, and a heat dissipation air duct is provided between two fins 171. The wind in the U-shaped air duct 15 can pass through the heat dissipation air duct to improve the heat dissipation effect of the fin 171. In this way, the power supply 17 is placed in the middle of the U-shaped air duct 15, and a plurality of fins 171 are provided on its surface. The fins 171 can increase the heat dissipation area of ​​the power supply 17 and improve the heat dissipation efficiency. A heat dissipation air duct is formed between the fins 171, so that the wind in the U-shaped air duct 15 can pass through the heat dissipation air duct, further improving the heat dissipation effect of the fin 171. By arranging a plurality of fins 171 on the power supply 17, and forming a heat dissipation air duct between the fins 171, the wind in the U-shaped air duct 15 can pass through the heat dissipation air duct, thereby increasing the contact area between the gas and the power supply 17 and improving the heat dissipation effect.

[0039] One end of the power supply 17 is connected to the inner wall of the power supply housing 1, and the power supply 17 is arranged on a side close to the vent 14. Figure 3As shown, a through hole 172 is provided on the power supply component 17, and the through hole 172 is adapted to the vent 14. More specifically, the power supply component 17 is arranged to be parallel to the baffle plate 13, one end of the power supply component 17 is connected to the inner wall of the power supply housing 1, and the other end faces the air inlet 11 or the air outlet 12. In this way, it can be understood that the power supply component 17 is arranged on one side of the vent, and the wind of the U-shaped air duct 15 can pass through the vent and then through the through hole 172 adapted to the vent 14, and then the wind can pass through the power supply component 17 from all sides, increasing the contact area between the gas and the power supply component 17, thereby improving the heat dissipation effect of the power supply component 17. One or more through holes 172 are provided on the power supply component 17, and these through holes 172 are adapted to the vent 14. The size and number of the through holes 172 can be adjusted according to the heat dissipation requirements of the power supply component 17. The through holes 172 can enable the wind to flow through the power supply component 17 more evenly, thereby increasing the contact area between the gas and the power supply component 17 and improving the heat dissipation effect. The power supply unit 17 is arranged on a side close to the vent 14. In this way, when the fan 16 is working, the wind in the U-shaped air duct 15 can pass through the vent 14 and then through the through hole 172 on the power supply unit 17, passing through the four sides of the power supply unit 17, thereby achieving efficient heat dissipation. Alternatively, the wind in the U-shaped air duct 15 can pass through the through hole 172 on the power supply unit 17 and then through the vent 14. In other words, multiple power supply units 17 can be arranged in the U-shaped air duct 15.

[0040] like Figure 2 As shown, the LED display screen power supply heat dissipation structure provided by the embodiment of the utility model further includes a temperature detection component 18, and the temperature detection component 18 is arranged in the power supply housing 1. Figure 1 As shown, more specifically, a power supply heat dissipation structure of an LED display screen provided by an embodiment of the utility model also includes a temperature display 19, which is arranged outside the power supply housing 1 and electrically connected to the temperature detection member 18. A temperature detection member 18 is arranged in the power supply housing 1 to monitor the temperature inside the power supply in real time. The temperature detection member 18 can select a high-precision temperature sensor to ensure the accuracy of the measurement data. The temperature display 19 is arranged outside the power supply housing 1 and electrically connected to the temperature detection member 18. The temperature display 19 can intuitively display the temperature data inside the power supply, which is convenient for users or maintenance personnel to understand the heat dissipation status of the power supply. Through the temperature detection member 18 and the temperature display 19, the temperature changes inside the power supply can be monitored in real time to ensure that the power supply operates within the normal operating temperature range. When the internal temperature of the power supply exceeds the preset safety threshold, the temperature display 19 can send an early warning signal to remind the user or maintenance personnel to take measures to dissipate heat in time. Combined with the temperature detection data, the heat dissipation structure can be further optimized, such as adjusting the position of the power supply member 17, increasing the number of heat dissipation fins 171, etc., to improve the heat dissipation efficiency.

[0041] Compared with the prior art, an LED display power supply heat dissipation structure provided by an embodiment of the utility model is provided, by arranging a baffle between the air inlet and the air outlet, one end of the baffle is connected to the power supply shell, and a vent is formed between the other end and the power supply shell, so that a U-shaped air duct is formed inside the power supply shell, one end of the U-shaped air duct is connected to the air inlet, and the other end is connected to the air outlet, and by arranging a fan on the U-shaped air duct, the heat dissipation inside the LED display power supply can be achieved by the air entering and exiting one side of the power supply shell, wherein the structure of the U-shaped air duct can better achieve the heat dissipation of the power supply shell as a whole.

[0042] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model.
