Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pump source cover technology, specifically a pump source cover that prevents high temperature. Background Technology
[0002] Fiber optic pump sources have advantages such as small size, light weight, high electro-optical conversion efficiency, high reliability, and long lifespan, and have important applications in fields such as industrial processing, biomedicine, and national defense. Inside the pump source, there are many stray lights that are not in the expected optical path. These lights are continuously reflected and refracted inside and are eventually absorbed by the shell and cover plate. The shell material is generally a material with good thermal conductivity, so the absorption of stray light does not have a significant impact on the shell temperature. However, the pump source cover plate is usually made of 304 stainless steel, which has poor thermal conductivity. After the cover plate absorbs stray light, the temperature in the local area can reach 70-80 degrees Celsius or even higher, which can cause the internal optical components to fail or even burn out the pump source.

[0020] The heat dissipation assembly 10 includes symmetrically arranged support frames 12, with the bottom of each support frame 12 fixedly connected to the outer top of the cover plate body 1. An upper heat dissipation pipe 13 and a lower heat dissipation pipe 14 are fixedly installed between the two support frames 12. The upper heat dissipation pipe 13 is horizontally aligned with the heat dissipation fins 9, and the lower heat dissipation pipe 14 is horizontally aligned with the heat dissipation channel 4. Five exhaust shrouds 15 are evenly fixedly installed on the outer side of the upper heat dissipation pipe 13, with the side of the exhaust shroud 15 away from the upper heat dissipation pipe 13 horizontally aligned with the heat dissipation fins 9. Four exhaust pipes 16 are evenly fixedly installed on the outer side of the lower heat dissipation pipe 14, with the ends of the four exhaust pipes 16 away from the lower heat dissipation pipe 14 respectively fixedly passing through and extending into the four heat dissipation channels. Inside one end of 4, a main pipe 17 is fixedly installed through the middle of the top of the lower heat dissipation pipe 14, and the bottom of the main pipe 17 is connected to the interior of the lower heat dissipation pipe 14. Branch pipes 18 are fixedly installed on the top of both sides of the main pipe 17, and both branch pipes 18 are connected to the main pipe 17. The ends of the two branch pipes 18 away from the main pipe 17 are fixedly connected to the upper heat dissipation pipe 13. The ends of the branch pipes 18 away from the main pipe 17 are connected to the interior of the upper heat dissipation pipe 13. A cooling fan 19 is fixedly installed on the outside of the main pipe 17. Positioning brackets 20 are fixedly installed on both sides of the cooling fan 19, and the ends of the positioning brackets 20 away from the cooling fan 19 are fixedly connected to the outside of the support bracket 12.
[0021] During use, the interaction of the cover plate body 1, strip groove 2, connecting groove 3, heat dissipation channel 4, side heat dissipation groove 5, heat conduction strip 6, concave groove 7, heat dissipation strip 8, heat dissipation fins 9, and heat dissipation component 10 enables the pump source cover plate to achieve better heat conduction and heat dissipation during use, preventing its temperature from becoming too high and ensuring that the pump source can work normally. Furthermore, the interaction of the fixed mounting base 21 and fixed mounting hole 22 allows the cover plate body 1 to be fixedly installed during use, which is convenient for operation and also ensures that the cover plate body 1 achieves better stability.
[0022] Working principle: During operation, firstly, fixing bolts matching the diameter of the fixing mounting hole 22 are used to fix the fixing mounting base 21 to the corresponding position on the pump source housing, thereby fixing the cover plate body 1 on the pump source housing. Then, during use, the concave groove 7 increases the contact area between the heat conduction strip 6 and the hot air at the bottom of the cover plate body 1, allowing the heat conduction strip 6 to better conduct heat to the heat dissipation strip 8, and then through the heat dissipation strip 8 to the heat dissipation fins 9 for dissipation. At the same time, some heat on the cover plate body 1 is conducted to the interior of the heat dissipation channel 4, and some heat is dissipated through the side heat dissipation groove 5. Simultaneously, the cooling fan 19 is started, and the cooling fan 19 blows air into the interior of the main pipe 17. Part of the airflow is transported through the main pipe 17. The airflow is sent to the interior of the lower heat sink 14, and then transported to the interior of the four heat dissipation channels 4 through the four air outlet pipes 16, blowing out the hot air inside the four heat dissipation channels 4. At the same time, a portion of the air blown out by the cooling fan 19 is diverted to the interior of the two branch pipes 18 through the main pipe 17, and then transported to the interior of the upper heat sink 13 through the two branch pipes 18. The airflow inside the upper heat sink 13 is output through the five air outlet shrouds 15. The airflow blown out by the five air outlet shrouds 15 blows air onto the heat dissipation fins 9 on the top of the five heat sinks 8, so that the heat dissipation fins 9 can quickly dissipate heat. This allows the pump source cover to achieve better heat conduction and heat dissipation during use, preventing its temperature from getting too high, and thus ensuring that the pump source can work normally.
