[0030] An efficient heat dissipation type LED display power supply provided by the utility model can effectively export the heat generated inside the power supply component to the outside of the power supply housing through the first heat dissipation channel by introducing the first heat dissipation component, that is, an active heat dissipation system including an inlet, an outlet and the first heat dissipation channel, by utilizing the principle of air convection.

Embodiment

[0031] An embodiment of the utility model provides an efficient heat dissipation type LED display power supply, as Figures 1 to 4 shown, which includes a power supply housing 10, a receiving space 110 is arranged inside the power supply housing 10, and a power supply component 120 is arranged inside the receiving space 110; a first heat dissipation component 20, the first heat dissipation component 20 includes an inlet 210, an outlet 220 and a first heat dissipation channel 230 connecting the inlet 210 and the outlet 220, the inlet 210 and the outlet 220 are arranged on the surface of the power supply housing 10, and the first heat dissipation channel 230 is arranged inside the power supply housing 10; a second heat dissipation component 30, the second heat dissipation component 30 includes a plurality of heat dissipation fins 310, a second heat dissipation channel 320 is formed between two adjacent heat dissipation fins 310, and the heat dissipation fins 310 are arranged on the surface of the power supply housing 10.

[0032] Among them, by introducing the first heat dissipation component 20, that is, an active heat dissipation system including an inlet 210, an outlet 220 and a first heat dissipation channel 230, the principle of air convection can be utilized to effectively export the heat generated inside the power supply component 120 to the outside of the power supply housing 10 through the first heat dissipation channel 230. This not only improves the heat transfer efficiency but also speeds up the heat dissipation rate, significantly reducing the operating temperature of the power supply component 120. The second heat dissipation component 30 can be composed of multiple heat dissipation fins 310, which not only increase the surface area of the power supply housing 10 but also form a second heat dissipation channel 320 between two adjacent fins. The increased surface area can greatly increase the contact area between the air and the heat source, further promoting heat exchange and dissipation, and effectively improving the overall heat dissipation performance. The efficient heat dissipation system helps to keep the power supply component 120 operating at a lower temperature, reducing the risk of aging, performance degradation or even damage of electronic components caused by high temperature. Therefore, this technical solution can improve the reliability and stability of the LED display power supply and extend its service life. Good heat dissipation performance also helps to reduce the temperature of the environment around the power supply and reduce the thermal impact on other electronic devices, thereby optimizing the operating environment of the entire LED display system and improving the overall performance and stability. This efficient heat dissipation structure enables the LED display power supply to better adapt to various high-temperature or harsh working environments, such as outdoor billboards, large event sites, etc., providing strong support for the wide application of LED displays.

[0033] Such as Figure 2As shown, the first heat dissipation channel 230 passes through the surface and / or inside of the power supply component 120. More specifically, a plurality of power supply components 120 are arranged in the accommodation space 110. More specifically, at least one first heat dissipation component 20 is correspondingly arranged for each power supply component 120. The heat dissipation channel is in direct contact with the outer surface of the power supply component 120, and can transfer the heat generated by the power supply component 120 to the air through heat conduction. This direct contact method can improve the heat dissipation efficiency, especially when the surface temperature of the power supply component 120 is relatively high. The first heat dissipation channel 230 may partially or completely pass through the inside of the power supply component 120. In this way, the heat inside the power supply component 120 can be more deeply derived, especially applicable to those power supply components 120 with relatively large internal heat generation. It can also be a combination of the above two structures, that is, the first heat dissipation channel 230 passes through the surface of the power supply component 120 and also penetrates into its interior, forming a comprehensive heat dissipation network. In this way, the surface heat can be quickly derived, and the heat accumulated inside can be effectively processed. To better control the heat dissipation of each power supply component 120, at least one first heat dissipation component 20 can be correspondingly arranged for each power supply component 120. This one-to-one configuration method can ensure that each power supply component 120 can obtain sufficient heat dissipation support. In some cases, if the heat dissipation requirements of the power supply components 120 are similar and the space permits, a one-to-many (that is, one heat dissipation component serves multiple power supply components 120) configuration method can also be adopted to simplify the structure and reduce costs. It can also be set in a many-to-one (that is, multiple heat dissipation components serve one power supply component 120) manner.

[0034] As Figure 1 and Figure 3 shown, more specifically, the inlet 210 and the outlet 220 are arranged on the same surface of the power supply housing 10. The inlet 210 and the outlet 220 are both located on the same surface of the power supply housing 10, which generally means that the heat dissipation channel extends along a certain direction (such as horizontal or vertical) of this surface. This can simplify the structure of the heat dissipation channel, enabling air to flow more directly and efficiently. To maximize the heat dissipation efficiency, the shapes, sizes of the inlet 210 and the outlet 220, and the channel between them can be carefully calculated and optimized. For example, a streamlined structure can reduce the resistance when air flows, improving the heat dissipation efficiency. Since the inlet 210 and the outlet 220 are both on the same surface, it is easier to set up dust-proof and waterproof structures to protect the power supply component 120 from the influence of the external environment.

[0035] As Figure 1 and Figure 3As shown, at least two faces of the power supply housing 10 are provided with a first heat dissipation component 20. More specifically, the heat dissipation fins 310 are integrally formed with the power supply housing 10. The fact that at least two faces of the power supply housing 10 are provided with the first heat dissipation component 20 means that heat can be dissipated simultaneously from multiple directions. This multi-face heat dissipation structure can more effectively reduce the temperature of the power supply component 120 and improve the overall heat dissipation efficiency. The heat dissipation fins 310 and the power supply housing 10 are made by an integral molding process, and there are no additional connecting parts or interfaces between them. This can improve the structural stability and durability. The integrally formed heat dissipation fins 310 can more effectively transfer heat from the power supply component 120 to the outside of the power supply housing 10, reducing the thermal resistance and the risk of heat accumulation.

[0036] As Figure 2 shown, at least two mounting parts 130 are provided on one side of the power supply housing 10, and a third heat dissipation channel 140 is formed between the two mounting parts 130. More specifically, it further includes a fan, and the air blown by the fan flows through at least one of the first heat dissipation channel 230, the second heat dissipation channel 320, and the third heat dissipation channel 140.

[0037] In this way, at least two mounting parts 130 are provided on one side of the power supply housing 10. These two mounting parts 130 are not only used to fix or mount the power supply module, but also cleverly form a third heat dissipation channel 140 therebetween. This structure makes full use of the space of the power supply housing 10 and increases an additional heat dissipation path. As Figure 2 shown, the first heat dissipation channel 230 and the third heat dissipation channel 140 can be respectively located on both sides of the power supply component 120, and the second heat dissipation channel 320 can be provided on the other side face of the power supply component 120, so as to further enhance the heat dissipation effect.

[0038] An efficient heat dissipation type LED display power supply provided by an embodiment of the present utility model further includes a blower, which is an active heat dissipation component, and its main function is to blow air to increase the heat dissipation effect. The air blown by the blower is set to flow through at least one or more of the first heat dissipation channel 230, the second heat dissipation channel 320, and the third heat dissipation channel 140, thereby strengthening the heat dissipation capacity of these channels. Among them, if the air blown by the blower flows through the first heat dissipation channel 230, it can directly accelerate the air flow in the channel and help to take out the heat inside the power supply component 120 more quickly. For the second heat dissipation channel 320 formed by the heat dissipation fins 310, the air flow of the blower can increase the heat exchange efficiency between the fins and the surrounding air, and further reduce the temperature of the power supply housing 10. As an additional heat dissipation path, the third heat dissipation channel 140, the air flow of the blower can further promote the heat exchange in this area, making the heat dissipation of the entire power supply housing 10 more uniform and efficient. The addition of the blower and the synergistic effect of multiple heat dissipation channels significantly improve the heat dissipation efficiency of the entire LED display power supply. This helps to reduce the working temperature of the power supply component 120 and improve the stability and reliability of the system. By reasonably arranging the mounting parts 130 and the heat dissipation channels, and integrating the blower, the internal space of the power supply housing 10 is fully utilized and optimized. This layout not only improves the heat dissipation efficiency, but also makes the entire power supply structure more compact and reasonable. The effective heat dissipation structure reduces the risk of aging, performance degradation or even damage of electronic components caused by high temperature. This helps to improve the overall reliability of the LED display power supply and extend its service life. Good heat dissipation performance helps to maintain the stable operation and high-quality display effect of the LED display, thereby enhancing the user's viewing experience.

[0039] Compared with the prior art, an efficient heat dissipation type LED display power supply provided by an embodiment of the present utility model, by introducing a first heat dissipation component, that is, an active heat dissipation system including an inlet, an outlet and a first heat dissipation channel, can utilize the principle of air convection to effectively export the heat generated inside the power supply component out of the power supply housing through the first heat dissipation channel. This structure not only improves the heat transfer efficiency, but also speeds up the heat dissipation speed, significantly reducing the working temperature of the power supply component. The second heat dissipation component includes a plurality of heat dissipation fins, which not only increase the surface area of the power supply housing, but also form a second heat dissipation channel between two adjacent fins. Such an increased surface area can increase the contact area between the air and the heat source, further promoting heat exchange and dissipation, and effectively improving the overall heat dissipation performance.

[0040] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model.
