[0001] The utility model relates to the technical field of LED driving power supplies, in particular to a high-efficiency heat dissipation type LED driving power supply device. Background Art

[0002] With the rapid development of LED lighting technology, LED lamps have been widely used in the lighting field due to their high efficiency, energy saving, and environmental protection. However, the normal operation of LED lamps is highly dependent on stable and efficient LED driver power supplies. During long-term operation, the internal components of the LED driver power supply will generate a lot of heat. If the heat dissipation is poor, it will directly lead to an increase in the temperature of the driver power supply, affecting the circuit performance, and even causing failures, shortening the service life of the LED lamp.

The heat dissipation device has a plurality of heat dissipation fins, which are evenly distributed outside the cylindrical cavity. Although the energy-saving high-power LED mining lamp is also provided with a fan device, a temperature sensor and a heat dissipation device, the driving power supply is a structure that generates a large amount of heat and is arranged on the upper surface of the fan device. The heat dissipation effect is still poor, and it is easy to malfunction due to overheating and has a short service life. Utility Model Content

DETAILED DESCRIPTION

[0031] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] like Figures 1 to 4 As shown, a high-efficiency heat dissipation type LED driving power supply device includes a driving power supply body 1, an outer shell 2, a heat dissipation inner shell 3, spiral fins 4, a heat dissipation fan 6, an air outlet cover 7 and a temperature sensor. Among them, the two ends of the outer shell 2 are connected with its inner cavity. The heat dissipation inner shell 3 is connected to the inner wall of the outer shell 2 through the spiral fins 4. A plurality of spiral fins 4 are evenly arranged around the outer peripheral wall of the heat dissipation inner shell 3. The inner wall of the outer shell 2, the outer wall of the heat dissipation inner shell 3 and the two adjacent spiral fins 4 form a spiral heat dissipation flow channel 5. The inner wall of the outer shell 2, the outer wall of the heat dissipation inner shell 3 and the two adjacent spiral fins 4 form a spiral heat dissipation flow channel 5. Compared with the straight heat dissipation air channel, the spiral heat dissipation air channel realizes multiple turns and uniform distribution of the airflow through its complex structure. This design not only increases the contact area of ​​the airflow, but also enables the heat to be more evenly dissipated in the entire air channel, accelerates the exchange of heat with the outside air, thereby effectively reducing the overall temperature of the device and achieving the effect of efficient heat dissipation. The driving power supply body 1 is installed in the heat dissipation inner shell 3. The cooling fan 6 is mounted on one end of the outer shell 2 and blows air toward the spiral cooling channel 5. The air outlet cover 7 is mounted on the other end of the outer shell 2. The temperature sensor is mounted on the heat dissipation inner shell 3 and is electrically connected to the cooling fan 6.

[0033] The high-efficiency heat dissipation type LED driving power supply device is combined by arranging a driving power supply body 1, an outer shell 2, a heat dissipation inner shell 3, spiral fins 4, a heat dissipation fan 6, an air outlet cover 7 and a temperature sensor, and adopts a combination design of the heat dissipation inner shell 3, the heat dissipation fins, the heat dissipation fan 6 and the temperature sensor to form an efficient heat dissipation system. On the one hand, there are a plurality of spiral fins 4 between the inner peripheral wall of the outer shell 2 and the outer peripheral wall of the heat dissipation inner shell 3, and heat is dissipated through the heat dissipation inner shell 3 and the heat dissipation fins to form a first heat dissipation; on the other hand, the temperature sensor monitors the temperature change of the heat dissipation inner shell 3 in real time, and forms an electrical connection with the heat dissipation fan 6 to realize intelligent temperature control. When the temperature sensor detects that the temperature of the heat dissipation inner shell 3 is higher than the set stability, the heat dissipation fan 6 starts to work and blows air toward the spiral heat dissipation flow channel 5 to take away the heat on the heat dissipation inner shell 3 and the spiral fins 4, so as to achieve the effect of rapid cooling and form a second heat dissipation. Under the design of double heat dissipation, the heat dissipation performance is significantly improved, the damage of the driving power supply body 1 due to overheating is effectively avoided, and its service life is extended, thereby achieving the effect of efficient heat dissipation and enhancing the stability and safety of the device.

[0034] Preferably, the temperature sensor is connected to the inner wall of the heat dissipation inner shell 3. Installing the temperature sensor on the inner wall of the heat dissipation inner shell 3, closer to the driving power supply body 1, can monitor the temperature change of the heat dissipation inner shell 3 faster and more accurately in real time, effectively avoiding damage to the driving power supply body 1 due to overheating.

[0035] In this embodiment, a mounting opening 31 for placing the heat dissipation inner shell 3 in the cavity is opened at one end of the heat dissipation inner shell 3; the left and right sides of the inner wall of the heat dissipation inner shell 3 are respectively provided with a first clip hook 9 and a second clip hook 10 for clamping and fixing the left and right sides of the driving power supply body 1; the driving power supply body 1 is embedded in the cavity of the heat dissipation inner shell 3 from the mounting opening 31 and is pressed and contacted with the other end of the heat dissipation inner shell 3; an end cover 11 is provided on one end of the heat dissipation inner shell 3, which is adapted to fit with the mounting opening 31 and presses the driving power supply body 1 to be fixed in the cavity of the heat dissipation inner shell 3. By setting the first card support hook portion 9, the second card support hook portion 10 and the end cover 11; the driving power supply body 1 is embedded into the cavity of the heat dissipation inner shell 3 from the installation port 31, and the left and right sides of the driving power supply body 1 are clamped and fixed by using the first card support hook portion 9 and the second card support hook portion 10, and then the end portion of the other end of the heat dissipation inner shell 3 and the end cover 11 are used to press the driving power supply body 1 to be fixed in the cavity of the heat dissipation inner shell 3, so that the driving power supply body 1 is stably installed in the heat dissipation inner shell 3, the structural connection is stable and reliable, and it is easy to disassemble and assemble.

[0036] In order to achieve a better heat dissipation effect when the driving power source body 1 is installed in the heat dissipation inner shell 3, a spacing space 12 is provided between the outer peripheral side wall of the driving power source body 1 and the inner peripheral side wall of the heat dissipation inner shell 3. Under the effect of the spacing space 12, there is a spacing between the driving power source body 1 and the inner peripheral side wall of the heat dissipation inner shell 3, so as to avoid the driving power source body 1 being tightly installed in the heat dissipation inner shell 3, and the heat dissipation effect is better.

[0037] In order to form a spiral air duct with better sealing performance, the cavity of the outer shell 2 is a cylindrical cavity; the heat dissipation inner shell 3 is cylindrical; and the spiral fin 4 has a spiral surface 41 that fits the inner peripheral side wall of the outer shell 2. The cavity of the outer shell 2, the heat dissipation inner shell 3 and the spiral surface 41 are designed in this way to form a spiral air duct with better sealing performance. When combined with the heat dissipation fan 6, the heat on the heat dissipation inner shell 3 and the spiral fin 4 is taken away, so as to achieve a rapid cooling effect and improve the heat dissipation efficiency of the device.

[0038] In addition, in this embodiment, there are three spiral fins 4. The spiral air duct is designed in this way, and the internal space of the spiral air duct is large, the heat dissipation area is increased, the airflow velocity is fast, the heat exchange with the outside air is accelerated, and the heat on the heat dissipation inner shell 3 and the spiral fins 4 is better taken away, so as to achieve the effect of rapid cooling and improve the heat dissipation efficiency of the device. Of course, the number of spiral fins 4 can be reasonably designed according to demand, and can also be 4, 5, 6, etc.

[0039] In order to improve the material of the high-efficiency heat dissipation type LED driving power supply device to achieve a better heat dissipation effect, the heat dissipation inner shell 3 and the spiral fins 4 are both made of copper or aluminum alloy.

[0040] In order to facilitate the wiring of the driving power source body 1 , a wire hole 8 communicating with the cavity of the heat dissipation inner shell 3 is provided on the other end of the heat dissipation inner shell 3 and the end cover 11 .

[0041] In this embodiment, a snap-fitting groove 21 is provided on the other end of the outer shell 2; a snap-fitting portion 71 adapted to snap-fit ​​with the snap-fitting groove 21 is provided on the air outlet cover 7 at a position corresponding to the snap-fitting groove 21. The heat dissipation fan 6 is mounted on one end of the outer shell 2 by means of a bolt 13. By providing the snap-fitting portion 71 to be snap-fitted with the snap-fitting groove 21, a simple detachable connection between the other end of the outer shell 2 and the air outlet cover 7 is realized, and a simple detachable connection between one end of the shell and the heat dissipation fan 6 is realized by means of the bolt 13, the structure is simple, and disassembly and assembly are convenient.

[0042] In summary, the embodiment of the utility model provides a high-efficiency heat dissipation type LED driving power supply device, wherein the high-efficiency heat dissipation type LED driving power supply device has the following advantages:

[0043] 1. The inner wall of the outer shell 2, the outer wall of the heat dissipation inner shell 3 and the two adjacent spiral fins 4 are surrounded to form a spiral heat dissipation flow channel 5. Compared with the straight heat dissipation duct, the spiral heat dissipation duct realizes multiple turns and uniform distribution of the airflow through its complex structure. This design not only increases the contact area of ​​the airflow, but also enables the heat to be more evenly dissipated in the entire air duct, accelerates the exchange of heat with the outside air, thereby effectively reducing the overall temperature of the device and achieving the effect of efficient heat dissipation.

[0044] 2. The high-efficiency heat dissipation type LED driving power supply device is combined by arranging a driving power supply body 1, an outer shell 2, a heat dissipation inner shell 3, spiral fins 4, a heat dissipation fan 6, an air outlet hood 7 and a temperature sensor, and adopts a combination design of a heat dissipation inner shell 3, heat dissipation fins, a heat dissipation fan 6 and a temperature sensor to form an efficient heat dissipation system. On the one hand, there are a plurality of spiral fins 4 between the inner peripheral wall of the outer shell 2 and the outer peripheral wall of the heat dissipation inner shell 3, and heat is dissipated through the heat dissipation inner shell 3 and the heat dissipation fins to form a first heat dissipation; on the other hand, the temperature sensor monitors the temperature change of the heat dissipation inner shell 3 in real time, and forms an electrical connection with the heat dissipation fan 6 to realize intelligent temperature control. When the temperature sensor detects that the temperature of the heat dissipation inner shell 3 is higher than the set stability, the heat dissipation fan 6 starts to work and blows air toward the spiral heat dissipation flow channel 5 to take away the heat on the heat dissipation inner shell 3 and the spiral fins 4, so as to achieve a rapid cooling effect and form a second heat dissipation. Under the design of double heat dissipation, the heat dissipation performance is significantly improved, and the damage of the driving power supply body 1 due to overheating is effectively avoided, and its service life is extended, thereby achieving the effect of efficient heat dissipation and enhancing the stability and safety of the device.
