[0001] This utility model relates to the field of communication base station cabinet technology, specifically a heat exchange device suitable for 5G communication base station cabinets. Background Technology

[0002] With the rapid development of 5G communication technology, heat dissipation in 5G base station cabinets has become a key factor restricting their efficient and stable operation. As 5G networks are fully deployed, the number of base stations is increasing dramatically, and the number and power consumption of their internal electronic devices are growing explosively. The peak power of 5G base stations can reach 3-4 times that of 4G base stations, and the density of 5G base stations is 2-3 times higher than that of 4G base stations, resulting in a large amount of heat being generated inside the cabinets.

[0003] Existing cabinet equipment typically uses fans to achieve heat exchange. However, fans are fixed with multiple bolts, which means that each bolt must be removed individually during maintenance. Especially when the bolts are corroded, the removal process may damage the bolt holes on the door panel, requiring subsequent tapping repair, which increases maintenance time and costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heat exchange device suitable for 5G communication base station cabinets, which solves the problem mentioned in the background technology that the fan is fixed by multiple bolts, which requires disassembling each bolt individually during maintenance, increasing maintenance time and costs.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0020] Example 1:

[0021] Please see Figures 1-4 This utility model provides a heat exchange device suitable for 5G communication base station cabinets, including a cabinet 1. The top left and right sides of the cabinet 1 are provided with heat dissipation holes 13. Heat dissipation components 2 are installed on the heat dissipation holes 13. Fixing components 3 are provided on both sides of the heat dissipation holes 13. The fixing components 3 include a snap-fit ​​frame 31. The snap-fit ​​frame 31 is provided with a snap-fit ​​groove 36. The heat dissipation component 2 includes a heat dissipation frame 21 with a heat dissipation fan 22 installed. Both ends of the heat dissipation frame 21 are provided with snap-fit ​​plates 24. The heat dissipation component 2 is installed in the snap-fit ​​groove 36 through the snap-fit ​​plates 24. A pressure plate 33 is provided in the snap-fit ​​groove 36. A moving rod 32 is fixedly installed on the back side of the pressure plate 33. The moving rod 32 passes through the snap-fit ​​frame 31. A spring 35 is sleeved on the moving rod 32. Both ends of the spring 35 are connected to the inner wall of the snap-fit ​​groove 36 and the pressure plate 33, respectively.

[0022] A guide plate 34 is provided on the pressure plate 33 near the opening of the snap-fit ​​groove 36, and the guide plate 34 is inclined.

[0023] A soft pad 23 is attached to the back side of the heat sink 21;

[0024] An air inlet 11 is provided at the bottom of the cabinet 1, and a metal frame 12 is provided on the top periphery of the air inlet 11. The metal frame 12 is located in the inner cavity of the cabinet 1.

[0025] A dustproof net 4 is installed in the cabinet 1. A magnetic suction plate 41 is installed around the dustproof net 4. The magnetic suction plate 41 is magnetically connected to the metal frame 12. The dustproof net 4 is installed on the metal frame 12 through the magnetic suction plate 41.

[0026] Another magnetic plate 41 and a dust filter 4 are installed on the air outlet surface of the heat sink 21. The dust filter 4 is magnetically attached to the heat sink 21 via the magnetic plate 41.

[0027] Specifically, the air inlet 11 at the bottom of cabinet 1 introduces external air into the cabinet. The air is filtered by the dust filter 4 before entering the inner cavity of cabinet 1. The cooling fan 22 in the heat sink 2 generates suction, causing the hot air inside cabinet 1 to be exhausted through the heat dissipation vent 13 at the top. The air inlet 11 and the heat dissipation vent 13 form an air circulation path, continuously carrying away the heat generated by the equipment inside cabinet 1, achieving heat exchange and heat dissipation. The soft pad 23 on the back of the heat sink 21 can directly contact cabinet 1. When the cooling fan 22 vibrates during operation, the soft pad 23 cushions the collision and friction between the heat sink 21 and cabinet 1, thereby reducing abnormal noise caused by vibration and maintaining quiet operation of the equipment. At the same time, the soft pad 23 also prevents wear and tear on components caused by direct hard contact between the heat sink 21 and cabinet 1, extending the service life of both. The dustproof net 4 on the air outlet surface of the heat dissipation bracket 21 prevents external dust from flowing back into the heat dissipation hole 13, and the dustproof net 4 at the air inlet 11 filters the incoming air. Together, they maintain the cleanliness of the inside of the cabinet 1 and prevent dust from affecting the heat dissipation effect.

[0028] During installation, the snap-fit ​​plate 24 of the heat sink 2 is aligned with the snap-fit ​​slot 36 of the snap-fit ​​bracket 31 and inserted. After the snap-fit ​​plate 24 contacts the guide plate 34, it pushes the pressure plate 33 along the inclined guide plate 34, causing the pressure plate 33 to compress the spring 35. This process eliminates the need for manual operation of the moving rod 32, simplifying the installation steps and improving installation efficiency. As the snap-fit ​​plate 24 continues to penetrate deeper into the snap-fit ​​slot 36 until it is fully inserted, the spring 35 releases some of its elasticity to push the pressure plate 33, causing the pressure plate 33 to press tightly against the snap-fit ​​plate 24. At this time, the spring 35 is still under a certain compression state, and the continuous elasticity ensures that the heat sink 2 is firmly installed and fixed. During disassembly, the heat sink 2 is pulled outwards to remove the snap-fit ​​plate 24 from the snap-fit ​​slot 36, completing the disassembly of the heat sink 2 for easy maintenance and cleaning.

[0029] The magnetic plate 41 provides a way to install and fix the dustproof net 4. The dustproof net 4 is magnetically connected to the metal frame 12 or the heat sink 21 through the magnetic plate 41, so that the dustproof net 4 can be installed and removed without tools and can be completed manually. This connection method facilitates the regular cleaning or replacement of the dustproof net 4, ensuring that the dustproof effect is always good, while avoiding the disassembly and assembly troubles of traditional fixing methods, reducing maintenance time and costs.

[0030] Working principle: When installing the heat sink 2, the snap-fit ​​plate 24 is aligned with the snap-fit ​​groove 36 of the snap-fit ​​bracket 31 and inserted. After the snap-fit ​​plate 24 contacts the guide plate 34, it pushes the pressure plate 33 along the inclined surface, so that the pressure plate 33 compresses the spring 35. After the snap-fit ​​plate 24 is fully inserted into the snap-fit ​​groove 36, the spring 35 releases part of the elastic force and pushes the pressure plate 33 to press the snap-fit ​​plate 24 tightly. At this time, the spring 35 is still in a certain compressed state. The continuous elastic force ensures that the heat sink 2 is installed firmly. The dustproof net 4 is magnetically connected to the metal frame 12 and the heat sink bracket 21 through the magnetic suction plate 41 on the periphery.

[0031] After the heat sink 2 and the dust filter 4 are installed in place, the cooling fan 22 of the heat sink 2 generates suction, which causes the hot air inside the cabinet 1 to be discharged through the top heat dissipation hole 13. The air inlet 11 at the bottom of the cabinet 1 introduces external air, which enters the inner cavity of the cabinet 1 after being filtered by the dust filter 4. The air inlet 11 and the heat dissipation hole 13 form an air circulation, and the heat of the internal equipment is carried away by the air circulation to achieve heat exchange and heat dissipation.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
