Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically a busbar with a heat dissipation structure. Background Technology

[0002] Busbar trunking is a busbar system composed of a metal plate (steel or aluminum plate) as a protective shell, conductive bars, insulation materials, and related accessories. It can be manufactured as a plug-in type enclosed busbar with plug-in junction boxes at intervals, or as a feeder type enclosed busbar without junction boxes in the middle. In the power supply systems of high-rise buildings, power and lighting circuits are often installed separately, and busbar trunking, as the main power supply line, is installed vertically along the wall in electrical shafts, one or more runs. Depending on its purpose, a typical run of busbar trunking consists of a starting busbar, a straight-through busbar (with and without plug-in holes), an L-shaped vertical (horizontal) bend busbar, a Z-shaped vertical (horizontal) offset busbar, a T-shaped vertical (horizontal) tee busbar, an X-shaped vertical (horizontal) four-way busbar, a variable-capacity busbar, an expansion busbar, terminal end caps, a terminal junction box, a plug-in box, related accessories, and fastening devices. Busbar trunking can be classified into three types according to its insulation method: air-insulated plug-in busbar trunking, compact insulated plug-in busbar trunking, and high-strength plug-in busbar trunking. According to its structure and application, it can be classified into compact insulated, air-insulated, air-supplemented insulated, fire-resistant, resin-insulated, and sliding-contact busbar trunking. According to its outer shell material, it can be classified into steel shell, aluminum alloy shell, and steel-aluminum hybrid shell busbar trunking.

[0003] However, existing busbar trunking has certain shortcomings that need to be improved. It cannot effectively dissipate heat, affecting its safety. It is also inconvenient to install and has poor fixing effect, which has a certain impact on actual use.

[0004] Chinese Utility Model Patent Publication No. CN 214153942 U discloses a busbar trunking with a heat dissipation structure. This busbar trunking, by incorporating a fan, dust filter, dehumidification layer, and heat dissipation plate, allows the fan to dissipate some of the heat generated during busbar operation through ventilation windows and absorb some of it through the heat dissipation plate. The dust filter and dehumidification layer prevent external dust and moisture from entering the trunking, effectively dissipating heat and ensuring safe operation. However, this busbar trunking lacks a detachable design for the fan, dust filter, dehumidification layer, and heat dissipation plate. Over time, dust easily accumulates on the fan and dust filter, making cleaning difficult and eventually affecting heat dissipation efficiency, thus reducing its practicality. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a busbar trunking with a heat dissipation structure, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is: a busbar trunking with a heat dissipation structure, including a busbar trunking body, a top plate located on the top of the busbar trunking body, and connecting modules located on both sides of the busbar trunking body. A flow guiding component that is slidably connected to a slide is provided on the side of the busbar trunking body away from the connecting module. A through hole is opened on the side of the busbar trunking body close to the flow guiding component. A heat dissipation component is provided on the side of the through hole away from the busbar trunking body.

[0007] The flow guiding assembly includes a flow guiding plate, an inlet section, an outlet section, a contraction section, and a slider. The flow guiding plate is disposed between the top plate and the busbar trunking body. One end of the flow guiding plate is provided with an inlet section, and the other end of the flow guiding plate is provided with an outlet section. The contraction section is disposed in the center of the flow guiding plate. Slider blocks are disposed at both ends of the flow guiding plate near the top plate and the busbar trunking body.

[0008] Preferably, a fixing plate is fixedly installed on both sides of the top plate, a protective plate is provided on both sides of the connecting module, an expansion buckle is fixedly installed on the end of the busbar trunking body near the heat dissipation component, and a locking block is provided on the side of the expansion buckle away from the heat dissipation component.

[0009] The above technical solution effectively protects the connection module by setting up a protective plate, and the heat dissipation components can be quickly fixed by the cooperation of the expansion buckle and the locking block, thus improving the installation efficiency.

[0010] Preferably, the heat dissipation assembly includes a heat-conducting plate, positioning holes, grooves, heat dissipation fins, and sealing strips. The heat-conducting plate is disposed inside the through hole. Positioning holes corresponding to expansion buckles are provided at both ends of the heat-conducting plate. A groove is provided at the end of the heat-conducting plate near the busbar trunking body. Heat dissipation fins are provided at the end of the heat-conducting plate away from the busbar trunking body. A sealing strip is provided on the side of the heat-conducting plate near the through hole.

[0011] The above technical solution incorporates a heat dissipation component, which effectively dissipates the heat generated inside the busbar trunking during operation, preventing excessive internal temperature from damaging internal components and improving the product's lifespan.

[0012] Preferably, the sealing strip can be inserted into the groove, and the sealing strip is provided in three identical sets, which are distributed at equal distances on the heat-conducting plate.

[0013] The above technical solution enables the quick installation of the sealing strip by matching the groove with the sealing strip. By setting three sets of identical sealing strips, it is possible to effectively prevent external dust from entering the interior of the busbar trunking body when the heat dissipation components are connected to the busbar trunking body. Over time, excessive dust inside the busbar trunking body will affect its use.

[0014] Preferably, the cross-section of the through hole is the same as the cross-section of the heat-conducting plate, and the heat-conducting plate and the through hole are connected by plug-in joint.

[0015] The above technical solution, by setting the heat-conducting plate and through hole for plug-in installation, enables rapid installation of the heat-conducting plate and busbar trunking body, effectively preventing misalignment during installation, improving installation efficiency while reducing installation difficulty.

[0016] Preferably, the locking block and the expansion buckle are mating components, and the expansion buckle and the positioning hole are mating components.

[0017] The above technical solution uses expansion buckles and positioning holes as mating components to position the heat-conducting plate during installation. In addition, the locking block and expansion buckles can be used as mating components to quickly fix the heat-conducting plate to the busbar trunking body. Furthermore, when the heat dissipation components need to be cleaned later, the heat-conducting plate and the busbar trunking body can be quickly disassembled, thereby improving work efficiency.

[0018] Preferably, the width of the outlet section is greater than the width of the inlet section, and the width of the contraction section is greater than the width of the outlet section.

[0019] With the above technical solution, when the flow guiding component is slidably installed on both sides of the bus trunking body, when the air enters from the inlet section and flows to the contraction section, the air pressure near the port on the leeward side of the contraction section is relatively low, which generates an adsorption effect and causes air flow, thereby accelerating the air circulation speed and effectively queuing the heat on the heat dissipation fins quickly, thereby improving the heat dissipation efficiency.

[0020] Compared with the prior art, the present invention provides a busbar trunking with a heat dissipation structure, which has the following advantages:

[0021] 1. This busbar trunking with a heat dissipation structure allows for quick installation of the heat-conducting plate and the busbar trunking body by first installing the sealing strip in the groove, then using the design of inserting the heat-conducting plate and the through hole, and further using the expansion buckle and positioning hole as matching components. This enables quick installation of the heat-conducting plate and the busbar trunking body, effectively preventing misalignment during installation, improving installation efficiency and reducing installation difficulty. The locking block and expansion buckle as matching components enable quick fixation of the heat-conducting plate and the busbar trunking body. It also facilitates quick disassembly of the heat-conducting plate and the busbar trunking body when cleaning the heat dissipation components later, thereby improving cleaning efficiency. By setting three sets of sealing strips, it is possible to effectively prevent external dust from entering the interior of the busbar trunking body when the heat dissipation components are connected to the busbar trunking body, improving the working environment of the internal components and thus extending the service life of the equipment.

[0022] 2. The busbar trunking with heat dissipation structure has a flow guiding component that is slidably installed on both sides of the busbar trunking body through the cooperation of a slider and a sliding groove. When the air enters from the inlet section and flows to the contraction section, the air pressure near the port on the leeward side of the contraction section is relatively low, which generates an adsorption effect and causes air flow, thereby accelerating the air circulation speed and effectively queuing the heat on the heat dissipation fins, thereby improving the heat dissipation efficiency.

[0031] 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.

[0032] Example 1: As Figure 1-7 As shown, the present invention provides a busbar trunking with a heat dissipation structure, including a busbar trunking body 1, a top plate 2 located on the top of the busbar trunking body 1, and connecting modules 4 located on both sides of the busbar trunking body 1. A flow guiding component 6 that is slidably connected to a slide 7 is provided on the side of the busbar trunking body 1 away from the connecting module 4. A through hole 8 is provided on the side of the busbar trunking body 1 close to the flow guiding component 6. A heat dissipation component 9 is provided on the side of the through hole 8 away from the busbar trunking body 1.

[0033] The flow guiding assembly 6 includes a flow guiding plate 601, an inlet section 602, an outlet section 603, a contraction section 604, and a slider 605. The flow guiding plate 601 is provided between the top plate 2 and the busbar trunking body 1. One end of the flow guiding plate 601 is provided with an inlet section 602, and the other end of the flow guiding plate 601 is provided with an outlet section 603. The contraction section 604 is provided in the middle of the flow guiding plate 601. Slider 605 is provided at both ends of the flow guiding plate 601 near the top plate 2 and the busbar trunking body 1.

[0034] Specifically, fixing plates 3 are fixedly installed on both sides of the top plate 2, and protective plates 5 are provided on both sides of the connecting module 4. An expansion buckle 10 is fixedly installed at the end of the busbar trunking body 1 near the heat dissipation component 9, and a locking block 11 is provided on the side of the expansion buckle 10 away from the heat dissipation component 9. The advantage is that the protective plates 5 can effectively protect the connecting module 4, and the cooperation between the expansion buckle 10 and the locking block 11 can achieve quick fixing of the heat dissipation component 9, thus improving installation efficiency.

[0035] Specifically, the heat dissipation component 9 includes a heat-conducting plate 901, a positioning hole 902, a groove 903, heat dissipation fins 904, and a sealing strip 905. The heat-conducting plate 901 is provided inside the through hole 8. Positioning holes 902 corresponding to the expansion buckle 10 are provided at both ends of the heat-conducting plate 901. A groove 903 is provided at the end of the heat-conducting plate 901 near the busbar trunking body 1. Heat dissipation fins 904 are provided at the end of the heat-conducting plate 901 away from the busbar trunking body 1. A sealing strip 905 is provided on the side of the heat-conducting plate 901 near the through hole 8.

[0036] The advantage is that the heat dissipation component 9 is set up, which can effectively dissipate the heat generated inside the bus trunking body 1 during operation, prevent the internal temperature from being too high and damage to the internal components, and improve the service life of the product.

[0037] Specifically, the sealing strip 905 can be inserted into the groove 903. Three identical sets of sealing strips 905 are provided, evenly distributed on the heat-conducting plate 901. The advantage is that by adapting the groove 903 to the sealing strip 905, quick installation of the sealing strip 905 is possible. Furthermore, by using three identical sets of sealing strips 905, it is easier to connect the heat dissipation component 9 to the busbar trunking body 1, effectively preventing external dust from entering the interior of the busbar trunking body 1. Over time, excessive dust accumulation inside the busbar trunking body 1 can affect its operation.

[0038] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, the cross-section of the through hole 8 is the same as that of the heat-conducting plate 901, and the heat-conducting plate 901 and the through hole 8 are connected by a plug-in joint. The advantage is that by designing the heat-conducting plate 901 and the through hole 8 to be connected by a plug-in joint, the heat-conducting plate 901 and the busbar trunking body 1 can be installed quickly, which can effectively prevent misalignment during installation, improve installation efficiency and reduce installation difficulty.

[0040] Specifically, the locking block 11 and the expansion buckle 10 are mating components, and the expansion buckle 10 and the positioning hole 902 are mating components. The advantage is that the expansion buckle 10 and the positioning hole 902, as mating components, can position the heat-conducting plate 901 during installation. Furthermore, the locking block 11 and the expansion buckle 10, as mating components, allow for quick fixing of the heat-conducting plate 901 to the busbar trunking body 1. This also allows for quick disassembly of the heat dissipation assembly 9 when cleaning it later, thus improving work efficiency.

[0041] Specifically, the width of the outlet section 603 is greater than the width of the inlet section 602, and the width of the contraction section 604 is greater than the width of the outlet section 603. The advantage is that when the flow guiding assembly 6 is slidably installed on both sides of the busbar trunking body 1, when air enters from the inlet section 602 and flows to the contraction section 604, the air pressure near the port on the leeward side of the contraction section 604 is relatively low, thus generating an adsorption effect and causing airflow. This accelerates the airflow speed, effectively dissipating heat from the heat dissipation fins 904 quickly, thereby improving heat dissipation efficiency.

[0042] Working principle: In use, the sealing strip 905 is first quickly installed in the groove 903. Then, the heat-conducting plate 901 and the through hole 8 are designed for plug-in installation. With the expansion buckle 10 and the positioning hole 902 as cooperating components, the heat-conducting plate 901 and the busbar trunking body 1 can be quickly installed. This effectively prevents misalignment during installation, improves installation efficiency, and reduces installation difficulty. The locking block 11 and the expansion buckle 10 are used as cooperating components to quickly fix the heat-conducting plate 901 and the busbar trunking body 1. This also facilitates the cleaning of the heat dissipation component 9 later. The quick disassembly of component 1 improves cleaning efficiency. By setting three sets of sealing strips 905, it is easy to connect the heat dissipation component 9 to the bus trunk body 1, effectively preventing external dust from entering the interior of the bus trunk body 1, improving the working environment of internal components, and thus extending the service life of the equipment. Subsequently, the flow guiding component 6 is slidably installed on both sides of the bus trunk body 1. When the air enters from the inlet section 602 and flows to the contraction section 604, the air pressure near the port on the leeward side of the contraction section 604 is relatively low, which generates an adsorption effect and causes air flow, thereby accelerating the air circulation speed and effectively quenching the heat on the heat dissipation fins 904, thereby improving the heat dissipation efficiency.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
