Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically a heat dissipation and ventilation structure for a multifunctional outdoor integrated distribution box. Background Technology

[0002] A distribution box is a low-voltage power distribution device that assembles switching equipment (such as circuit breakers), measuring instruments, protective electrical appliances (such as fuses), and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. It is one of the core devices for power distribution.

[0003] Existing distribution boxes require fans for cooling, but ordinary fans have limited cooling effect because their small airflow results in slow air circulation inside the box. This is especially problematic in hot summers, when the metal material of the distribution box causes even higher internal temperatures, making cooling with ordinary fans significantly less effective. Therefore, we propose a multi-functional outdoor integrated distribution box cooling and ventilation structure. Utility Model Content

[0004] This utility model provides a heat dissipation and ventilation structure for a multifunctional outdoor integrated power distribution box, which has the advantages of large air intake and good air blowing effect, and solves the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A heat dissipation and ventilation structure for a multifunctional outdoor integrated power distribution box includes a support frame, with legs at the four corners of the bottom of the support frame, and mounting plates at the bottom of both ends of the support frame. The mounting plates are mounted on the legs, and each mounting plate has a mounting opening in the middle. A fan housing is mounted on one side of the two mounting plates that are close to each other. The air inlet of the fan housing corresponds to the mounting opening. A fan wheel is provided inside the fan housing and is mounted on a drive shaft. The drive shaft and the fan housing are coaxially arranged and rotatably connected. The two drive shafts are connected to a drive device at their close ends. The top of the support frame is used to mount the power distribution box, and the air outlet of the fan housing extends into the power distribution box.

[0006] Preferably, the drive device includes a dual-head motor disposed between drive shafts, with both ends of the dual-head motor connected to the drive shafts respectively. The dual-head motor is mounted on a motor bracket, and both ends of the motor bracket are connected to support legs respectively.

[0007] Preferably, the edge of the fan casing is provided with a mounting base, and when the air inlet of the fan casing is placed inside the mounting port, the mounting base and the mounting plate are detachably connected.

[0008] Preferably, the air outlets of the fan casing are connected to the air inlet box via air guide pipes, and the air inlet box is installed on the bottom surface inside the distribution box.

[0009] The top of the air inlet box is sealed by two baffles. The sides of the two baffles that are far apart from each other are rotatably connected to the top of the air inlet box, allowing the baffles to rotate freely around the top of the air inlet box.

[0010] Both ends of the air inlet box are equipped with limiting devices corresponding to the baffles. Under the action of the limiting devices, the maximum opening angle of the baffles is less than 90°.

[0011] Preferably, the limiting device includes side plates located at the top of both ends of the air inlet box. The side plates are provided with baffles on both sides near the baffles. When the baffles are pushed open by the airflow, the baffles contact the baffles. When the airflow disappears, the two baffles automatically cover the top of the air inlet box due to gravity.

[0012] Preferably, the bottom of each outrigger is mounted on a support, which is mounted on a base.

[0013] Preferably, sealing plates are provided on both sides of the lower part of the support frame, and the sealing plates are connected to the support legs.

[0014] Compared with the prior art, in use, the dual-head motor drives the impeller to rotate inside the fan housing, so that the airflow from the air outlet of the fan housing fills the air inlet box. The airflow pushes open the two baffles, and then the airflow flows upward from the gap between the two baffles. The rising airflow blows away the heat of the electrical equipment. Moreover, when the two baffles are open, a strip-shaped opening is automatically formed between their tops. In this way, the airflow can blow upward with a certain area when it blows out of the opening. The airflow area is large and the heat dissipation effect is good. In addition, the dual-head motor and the fan housing are both located below the distribution box, so as not to occupy the internal space of the distribution box. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1 to 5 This utility model provides a technical solution: a heat dissipation and ventilation structure for a multifunctional outdoor integrated power distribution box, including a support frame 19, with legs 12 at the four corners of the bottom of the support frame 19, the bottom of each leg 12 being mounted on a support 13, the support 13 being mounted on a base 1, the base 1 being a concrete base, and the base 1 and the support 13 being mounted together by expansion bolts.

[0024] Mounting plates 3 are provided at both ends of the support frame 19. The mounting plates 3 are mounted on the legs 12. Each mounting plate 3 has a mounting opening 4 in the middle, which is a circular opening. A fan housing 2 is installed on the side of the two mounting plates 3 that are close to each other. The air inlet of the fan housing 2 corresponds to the mounting opening 4. The fan housing 2 is installed as follows: a mounting seat 11 is provided on the edge of the fan housing 2. The fan housing 2 is placed on the side of the mounting plate 3. At this time, the air inlet of the fan housing 2 can be placed in the mounting opening 4. Then, the mounting seat 11 is detachably connected to the mounting plate 3. The two are fastened with bolts, which makes it easy to install and remove the fan housing 2.

[0025] The fan housing 2 houses a fan impeller. Compared to a fan, the impeller exerts greater pressure during rotation, thus requiring a larger air intake. The impeller is mounted on the drive shaft 16. During installation, the drive shaft 16 must be coaxially aligned with the fan housing 2 and rotated together, allowing the impeller to rotate within the fan housing 2. In this configuration, the impeller and fan housing 2 together form the fan. The ends of the two drive shafts 16, close to each other, are connected to a drive unit. This drive unit simultaneously drives the impeller to rotate, drawing in cool outside air into the fan housing 2 and expelling it from the outlet. Figure 2 and Figure 3As shown, the drive device includes a dual-head motor 15 disposed between drive shafts 16. The two ends of the dual-head motor 15 are respectively connected to drive shafts 16, and the two are specifically connected by a coupling. The dual-head motor 15 is mounted on a motor bracket 14, and the two ends of the motor bracket 14 are respectively connected to support legs 12.

[0026] The motor bracket 14 includes two strip-shaped seats distributed below the dual-head motor 15. Figure 3 (As indicated by arrow A), the legs of the dual-head motor 15 are bolted to the strip-shaped base. Both ends of the strip-shaped base are connected to the strip-shaped rod, and both ends of the strip-shaped rod are fixed to the support leg 12. For example... Figure 3 As shown, the two strip seats are located below the dual-head motor 15, and there is a certain gap between them and the mounting plate 3, which facilitates the installation of the fan housing 2.

[0027] Based on the above embodiments, the distribution box 9 is installed on top of the support frame 19, and the air outlets of the fan casing 2 all extend into the distribution box 9. This is to allow the airflow generated by the fan wheel to be sent into the distribution box 9. Figure 4 As shown, a hole corresponding to the air outlet is provided at the bottom of the distribution box 9 (e.g., Figure 4 (As indicated by the middle arrow B), when the fan casing 2 is installed, the air outlet can be placed inside the hole and extended into the distribution box 9;

[0028] The airflow from the outlet can be directly sent into the distribution box 9, or the outlet of the fan casing 2 can be connected to the air inlet box 6 through the air guide pipe 18. The air inlet box 6 is installed on the bottom surface inside the distribution box 9. The top of the air inlet box 6 is sealed by two baffles 5. The sides of the two baffles 5 that are far apart from each other are rotatably connected to the top of the air inlet box 6, so that the baffles 5 can rotate freely around the top of the air inlet box 6. Both ends of the air inlet box 6 are equipped with limiting devices corresponding to the baffles 5. The limiting devices are set to prevent the opening angle of the baffles 5 from exceeding 90°. Figure 4 and Figure 5 As shown, the limiting device includes side plates 8 located at the top of both ends of the air inlet box 6. The side plates 8 are respectively provided with baffles 17 on both sides near the baffles 5. When the baffles 5 are pushed open by the airflow, the baffles 5 contact the baffles 17. Under the action of the limiting device, that is, under the obstruction of the baffles 17, the maximum angle of the baffles 5 opening is less than 90°. In other words, when the airflow from the air outlet fills the air inlet box 6, the air pressure inside the air inlet box 6 opens the two baffles 5, and then the airflow flows upward from the gap between the two baffles 5. When the dual-head motor 15 stops rotating, the airflow inside the air inlet box 6 disappears, and the two baffles 5 automatically cover the top of the air inlet box 6 due to gravity, thereby sealing the top of the air inlet box 6.

[0029] It should be emphasized that the side plate 8 and the baffle 5 are fitted with a gap, and the side plate 8 can also prevent airflow from flowing out from both sides of the baffle 5;

[0030] The baffle 5 can be equipped with a counterweight to give it a certain downward pressure capability. This allows the baffle 5 to close quickly when the airflow disappears. When the two baffles 5 are open, a strip-shaped opening is formed between the tops of the two baffles 5. This allows the airflow to blow upwards with a certain area when it blows out of the opening, so that the airflow can blow better onto the electrical equipment.

[0031] Based on the above embodiments, further optimization can be achieved by providing sealing plates 7 on both sides of the lower part of the support frame 19. The sealing plates 7 are connected to the support legs 12, so that the lower part of the support frame 19 is sealed by the sealing plates 7 and the mounting plates 3.

[0032] In practical applications, the dual-head motor 15 will also generate heat when it is working. Therefore, heat dissipation vents can be opened on the sealing plate 7 and the mounting plate 3, and a fan can be installed on the drive shaft 16 or the shaft of the dual-head motor 15. The fan will rotate with the drive shaft 16 or the dual-head motor 15, thereby dissipating the heat generated by the dual-head motor 15 and cooling it down.

[0033] Based on the above embodiments, further optimization is possible. At least one ventilation opening 10 is provided on both sides of the top of the distribution box 9. An exhaust fan can be installed in the ventilation opening 10 to quickly exhaust the air inside the distribution box 9.

[0034] Based on the above embodiments, further optimizations can be made, with filters detachably installed on both the vent 10 and the air inlet of the fan housing 2.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
