Description

Technical Field

[0001] This utility model belongs to the field of LED power supply heat dissipation technology, and specifically relates to a heat dissipation mechanism for LED power supplies. Background Technology

[0002] LED power supplies are a type of power supply that provides power to electronic devices. They are also known as power supplies, which convert alternating current (AC) into direct current (DC) through transformers and rectifiers. This device is called a rectifier power supply or a driver power supply. However, existing LED power supplies have poor heat dissipation. Generally, they rely on a simple cooling fan for heat dissipation, making it difficult to quickly dissipate the heat generated by electrical components, which significantly affects their lifespan. Therefore, we propose a heat dissipation mechanism for LED power supplies. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation mechanism for LED power supplies. By designing a shell, sealing plate, heat dissipation box, box cover, driver power supply, and heat dissipation components, the heat generated by the driver power supply during operation can be quickly absorbed by the heat-absorbing copper sheet and transferred to the copper tube, and then quickly absorbed again by the heat dissipation fins. Finally, it is quickly discharged from the heat dissipation holes by the cooling fan, which effectively improves the heat dissipation performance of the LED power supply, increases its service life, and has a compact overall structure and strong practicality.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation mechanism for an LED power supply, comprising a housing, a sealing plate at the top of the housing, a heat dissipation box inside the housing, a box cover at the top of the heat dissipation box, a driving power supply installed inside the heat dissipation box, and a heat dissipation component on the side of the heat dissipation box. The heat dissipation component includes a copper tube installed on the side of the heat dissipation box, a heat-absorbing copper fin connected to the end of the copper tube near the driving power supply, the side of the heat-absorbing copper fin away from the copper tube being attached to the surface of the driving power supply, heat dissipation fins fixedly sleeved on the surface of the copper tube, a horizontal plate on one side of the heat dissipation fins, a cooling fan installed on the side of the horizontal plate, and heat dissipation holes on the side of the housing.

[0005] Preferably, it also includes an auxiliary component, which includes a frame located on one side of the heat dissipation hole, a dustproof mesh provided on the inner side of the frame, and fixing screws provided at the four corners of the side of the frame.

[0006] Preferably, the distance between the horizontal plate and the heat dissipation fins is two centimeters.

[0007] Preferably, the crossbar is made of plastic.

[0008] Preferably, the side of the frame is parallel to the side of the outer shell.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. By designing the outer shell, sealing plate, heat dissipation box, box cover, driver power supply, and heat dissipation components, the heat generated by the driver power supply during operation can be quickly absorbed by the heat-absorbing copper fins and transferred to the copper pipe, then quickly absorbed again by the heat dissipation fins, and finally quickly discharged from the heat dissipation holes by the cooling fan. This effectively improves the heat dissipation performance of the LED power supply, increases its service life, and has a compact overall structure with strong practicality.

[0011] 2. By designing auxiliary components, external dust will not easily enter the LED power supply during use, thus ensuring that the heat dissipation performance of the LED power supply is not affected. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a technical solution: a heat dissipation mechanism for an LED power supply, including a housing 1, a sealing plate 2 at the top of the housing 1, a heat dissipation box 3 inside the housing 1, a box cover 4 at the top of the heat dissipation box 3, a driver power supply 5 installed inside the heat dissipation box 3, and a heat dissipation component on the side of the heat dissipation box 3. The heat dissipation component includes a copper pipe 7 installed on the side of the heat dissipation box 3, a heat-absorbing copper fin 6 connected to the end of the copper pipe 7 near the driver power supply 5, the side of the heat-absorbing copper fin 6 away from the copper pipe 7 being in contact with the surface of the driver power supply 5, and heat dissipation fins 8 fixedly sleeved on the surface of the copper pipe 7. A horizontal plate 9 is also provided on one side of the heat dissipation fins 8, and a cooling fan 10 is installed on the side of the horizontal plate 9. Heat dissipation holes 11 are also provided on the side of the housing 1. The distance between the horizontal plate 9 and the heat dissipation fins 8 is two centimeters, so that the heat dissipation fan 10 on the horizontal plate 9 can be effectively dissipated. The hot air fan 10 can better remove the heat from the heat sink fins 8, and the horizontal plate 9 is made of plastic, which effectively saves material costs. The heat dissipation effect of existing LED power supplies is poor. Generally, they are cooled by a simple cooling fan inside. The heat generated by electrical components is not easily dissipated quickly, which has a significant impact on their service life. By designing the outer shell 1, sealing plate 2, heat dissipation box 3, box cover 4, driver power supply 5, and heat dissipation components, the heat generated by the driver power supply 5 when it is working can be quickly absorbed by the heat-absorbing copper plate 6 and transferred to the copper pipe 7, and then quickly absorbed by the heat sink fins 8. Finally, it is quickly discharged from the heat dissipation hole 11 by the cooling fan 10, which effectively improves the heat dissipation performance of the LED power supply, increases its service life, and has a compact overall structure with strong practicality.

[0018] In this embodiment, preferably, please refer to... Figure 1 As shown, it also includes auxiliary components, including a frame 12 located on one side of the heat dissipation hole 11. A dustproof mesh 13 is provided on the inner side of the frame 12, and fixing screws 14 are provided at the four corners of the side of the frame 12. The side of the frame 12 is parallel to the side of the outer shell 1, so that there is no gap between the frame 12 and the outer shell 1 after the frame 12 is installed in the designated position. By designing auxiliary components, external dust will not easily enter the inside of the LED power supply during use, thereby ensuring that the heat dissipation performance of the LED power supply will not be affected.
