Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a compact distribution box with an embedded heat dissipation duct. Background Technology

[0002] Commercially available distribution boxes typically have cooling ducts to dissipate heat from their internal electrical components. These ducts draw in cool external air, carrying away the heat from the internal components before leaving the distribution box. However, when these distribution boxes are used in dusty environments, dust can enter the box with the air, contaminating the electrical components and causing short circuits and other malfunctions. To address this issue, we need to innovate the technology based on existing distribution boxes. Utility Model Content

[0003] The purpose of this invention is to provide a compact distribution box with an embedded heat dissipation duct to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compact distribution box with an embedded heat dissipation duct, comprising:

[0005] The distribution box has a groove on the rear side of its inner wall and an air duct at its bottom. The groove is connected to the air duct. There are exhaust vents on both the left and right sides of the distribution box, and the exhaust vents are connected to the air ducts. A heat-conducting plate is installed in the groove. Heat dissipation fins are evenly placed in the air duct. A dustproof plate is installed at the bottom of the distribution box. The heat dissipation fins are evenly arranged on the top of the dustproof plate. A cooling fan is installed in the exhaust vent.

[0006] Preferably, the front side of the heat-conducting plate is flush with the rear side of the inner wall of the distribution box, and the front side of the heat-conducting plate is uniformly provided with heat-conducting grooves. The heat-conducting plate is located on the rear side of the vertical mounting bracket inside the distribution box.

[0007] Preferably, the rear side of the heat-conducting plate is in contact with the front side of the heat dissipation fins, and a convex block is provided on the rear side of the heat dissipation fins.

[0008] Preferably, the rear side of the air duct is uniformly provided with convex grooves, the convex grooves penetrate the bottom of the distribution box, and the convex blocks are disposed in the convex grooves.

[0009] Preferably, the bottom of the dustproof plate has two sets of through holes evenly distributed throughout, and the bottom of the distribution box has two sets of threaded holes evenly distributed throughout.

[0010] Preferably, a bolt is provided in the through hole, and the bolt is screwed into the threaded hole. Two sets of fixing ears are evenly provided on the left and right sides of the distribution box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention separates the air duct from the inner cavity of the distribution box using a heat-conducting plate, thereby preventing dust from entering the distribution box through the air duct. Furthermore, since the heat-conducting plate is close to the vertical mounting bracket inside the distribution box, it can quickly absorb the heat generated by the electrical components and conduct it to the heat dissipation fins, where it is cooled by the cooling fan.

[0013] By opening air ducts on the outside of the distribution box and installing heat dissipation fins inside the air ducts, while embedding heat conduction plates inside the air ducts, the heat dissipation components can be made to not occupy the internal space of the distribution box, and the structure of the entire distribution box can be made more compact.

[0014] By unscrewing the bolts, the dust cover and heat sink fins can be easily moved downwards and pulled out, making it easy to clean the dust cover, heat sink fins, the inside of the air duct, and the back of the heat conduction plate, thus improving the convenience of dust cleaning of the device.

[0021] 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.

[0022] Please see Figures 1-5 A compact distribution box with an embedded heat dissipation duct includes a distribution box 1. A groove is formed on the rear side of the inner wall of the distribution box 1. A duct is formed at the bottom of the distribution box 1, and the groove is connected to the duct. A set of exhaust vents is formed on both the left and right sides of the distribution box 1, and the exhaust vents are connected to the duct. A heat-conducting plate 11 is fixedly installed in the groove, separating the duct from the inner cavity of the distribution box 1 to prevent dust from entering the distribution box 1 through the duct. Heat dissipation fins 16 are evenly arranged in the duct. A dustproof plate 14 is placed at the bottom of the distribution box 1, and the heat dissipation fins 16 are evenly fixedly arranged on the top of the dustproof plate 14. A set of exhaust vents is fixedly installed in the exhaust vents. The front side of the heat-conducting plate 11 is flush with the rear side of the inner wall of the distribution box 1. The front side of the heat-conducting plate 11 has evenly distributed heat-conducting grooves. The heat-conducting plate 11 is located behind the vertical mounting bracket inside the distribution box 1. When electrical components on the vertical mounting bracket inside the distribution box 1 generate heat, the heat-conducting plate 11 can absorb the heat generated by the electrical components due to its proximity to the vertical mounting bracket. Furthermore, the heat-conducting grooves on the surface of the heat-conducting plate 11 increase the contact area between the heat-conducting plate 11 and the air, thereby improving the efficiency of the heat-conducting plate 11 in absorbing the heat generated by the electrical components. Heat absorbed by the heat plate 11 is conducted to the heat dissipation fins 16. At this time, the cooling fan 13 drives external air through the dustproof plate 14 into the air duct, providing air cooling to the heat plate 11 and the heat dissipation fins 16. The airflow is then exhausted through the exhaust vent. The rear side of the heat plate 11 is in contact with the front side of the heat dissipation fins 16. A convex block 17 is fixedly installed on the rear side of the heat dissipation fins 16. Convex grooves are evenly distributed on the rear side of the air duct, penetrating the bottom of the distribution box 1. The convex block 17 is slidably disposed within the convex grooves. Two sets of through holes are evenly distributed through the bottom of the dustproof plate 14, and two sets of threaded holes are evenly distributed on the bottom of the distribution box 1. The through holes are equipped with… There is a bolt 15, which is screwed into the threaded hole. The convex block 17 is inserted into the convex groove, so that the heat dissipation fin 16 can be stabilized on the back side of the heat conduction plate 11. Then, the bolt 15 passes through the through hole of the dustproof plate 14 and is screwed into the threaded hole of the distribution box 1, so as to fix the dustproof plate 14 to the bottom of the distribution box 1, and then fix the heat dissipation fin 16 in the air duct. The dustproof plate 14 can perform preliminary filtration of the air entering the air duct. Two sets of fixing ears 12 are evenly fixed on the left and right sides of the distribution box 1, respectively. Expansion bolts are used to pass through the fixing ears 12 and connect to the bolt holes on the wall, so as to install the distribution box 1 on the wall.

[0023] Working principle: Expansion bolts are used to connect the fixing lugs 12 to the bolt holes on the wall, thereby installing the distribution box 1 on the wall. The convex block 17 is inserted into the convex groove, thus stabilizing the heat dissipation fins 16 behind the heat-conducting plate 11. Then, bolts 15 are threaded through the through holes of the dustproof plate 14 and screwed into the threaded holes of the distribution box 1, thus fixing the dustproof plate 14 to the bottom of the distribution box 1, and further fixing the heat dissipation fins 16 inside the air duct. The dustproof plate 14 provides preliminary filtration of the air entering the air duct. The heat-conducting plate 11 separates the air duct from the inner cavity of the distribution box 1, thus preventing dust from entering the distribution box 1 through the air duct. When the electrical components on the vertical mounting bracket inside the distribution box 1 generate heat, the heat-conducting plate 11, being close to the vertical mounting bracket, absorbs this heat. Furthermore, the heat-conducting grooves on the surface of the heat-conducting plate 11 increase its contact area with the air, thereby improving its efficiency in absorbing the heat. The absorbed heat is then conducted to the heat dissipation fins 16. At this point, the cooling fan 13 draws external air through the dustproof plate 14 into the air duct, cooling the heat-conducting plate 11 and the heat dissipation fins 16. The airflow is then exhausted through the exhaust vent.

[0024] By opening an air duct on the outside of the distribution box 1 and installing the heat dissipation fins 16 inside the air duct, while embedding the heat conduction plate 11 inside the air duct, the heat dissipation components do not occupy the internal space of the distribution box 1, and the structure of the entire distribution box 1 can be more compact. When the distribution box 1 is in heat dissipation operation for a long time, the dustproof holes on the dustproof plate 14 will be blocked by dust, and dust will accumulate in the air duct. At this time, after unscrewing the bolt 15, the dustproof plate 14 and the heat dissipation fins 16 can be moved downward and pulled out, so that the dustproof plate 14 and the heat dissipation fins 16 can be easily cleaned. At the same time, a cleaning stick can be inserted into the air duct to wipe it, so as to clean the air duct and the heat conduction plate 11, thereby improving the convenience of dust cleaning of the device.
