Description

Technical Field

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

[0002] Busbar trunking is a closed metal device made of copper or aluminum busbars. It is mainly used to distribute large power to various components of a distributed system. Busbar trunking is usually composed of conductive bars, insulation materials and related accessories. In low-voltage power transmission trunk line projects, busbar trunking has increasingly replaced traditional wires and cables. It can reduce phase-to-phase short-circuit electromagnetic forces and is widely used in building power supply system wiring. The heat dissipation capacity of busbar trunking is particularly important. Busbar trunking with good heat dissipation capacity can quickly dissipate internal heat, thereby reducing or avoiding the impact of heat on the interior.

[0003] While traditional busbar trunking possesses a certain heat dissipation capability, it also has some shortcomings. For example, its heat dissipation structure is relatively simple, making it difficult to guarantee the heat dissipation effect of the trunking through a single method. Consequently, the internal heat can easily be severely affected by the inability to dissipate heat in a timely manner. In addition, the shape of its heat dissipation structure is relatively fixed, making it difficult to seal and protect when not in use. This allows external dust and impurities to easily enter the trunking and cause certain impacts. Therefore, a heat-dissipating busbar trunking is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a heat dissipation busbar trunking with a variety of heat dissipation structures. Therefore, it can ensure the heat dissipation effect of the trunking through dual heat dissipation methods, so that the internal structure of the trunking is not easily affected by the inability to dissipate the internal heat in time. In addition, the shape of its heat dissipation structure is relatively flexible, so it can be sealed and protected when not in use, so that external dust and impurities are not easily allowed to enter the trunking and cause problems, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heat dissipation busbar trunking includes a trunking body. A plurality of first heat dissipation components are arranged at equal intervals on the upper part of the trunking body. A protective cover is provided above each of the first heat dissipation components.

[0024] Please see Figure 1-6 This utility model provides a technical solution:

[0025] A heat dissipation busbar trunking includes a trunking body 1. A plurality of first heat dissipation components 2 are arranged at equal intervals on the upper part of the trunking body 1. A protective cover 3 is provided above the first heat dissipation components 2. A snap-fit ​​component 4 is provided between the first heat dissipation components 2 and the protective cover 3. The first heat dissipation components 2 and the protective cover 3 are connected by the snap-fit ​​component 4. A connecting component 5 is provided between the first heat dissipation components 2 and the trunking body 1. A plurality of first heat dissipation holes 6 are arranged at equal intervals on the front and rear walls of the trunking body 1. Second heat dissipation components 7 are provided on both the front and rear sides of the trunking body 1.

[0026] The first heat dissipation component 2 includes a heat-conducting support plate 201. Multiple heat-conducting seats 202 are arranged at equal intervals and fixedly connected to the top of the heat-conducting support plate 201. Heat dissipation fins 203 are fixedly connected to the top of each heat-conducting seat 202. The first heat dissipation component 2 can provide good heat dissipation for the tank 1, thus enabling the internal heat of the tank 1 to dissipate in a timely manner, preventing the internal structure from being affected by the inability to dissipate internal heat in a timely manner. The snap-fit ​​component 4 includes a positioning block 401 fixedly connected to the bottom of the side wall of the protective cover 3 and positioning slots 402 opened on both sides of the top of the heat-conducting support plate 201. The positioning block 401 and the positioning slots 402 are positioned correspondingly and matched in specifications. 4 can provide good positioning capability between the protective cover 3 and the first heat dissipation component 2, thus preventing the protective cover 3 from shifting or falling off during protection, thereby ensuring the protective effect of the protective cover 3 on the first heat dissipation component 2; the connecting component 5 includes connecting support plates 501 symmetrically and fixedly connected to the bottom of the two side walls of the heat conduction support plate 201, with connecting bolts 502 penetrating through the center of the connecting support plate 501, and connecting screw holes 503 with the same number, corresponding position and matching specifications as the connecting bolts 502 on the top of the tank 1. The connecting component 5 can provide good connection capability between the first heat dissipation component 2 and the tank 1, thus ensuring the structural stability of the first heat dissipation component 2 during normal use. The first heat dissipation component 2 can be disassembled and replaced when damaged, thus facilitating later maintenance; the second heat dissipation component 7 includes sliding supports 701 symmetrically arranged on the left and right and slidably connected to the front and rear walls of the tank 1. A sliding support plate 702 that fits against the front and rear walls of the tank 1 is fixedly connected between the two sliding supports 701. A number of second heat dissipation holes 703 are equally spaced on the sliding support plate 702, with the same number, corresponding position, and matching specifications as the first heat dissipation holes 6. A limit block 704 is fixedly connected to the side wall of the sliding support 701 away from the sliding support plate 702. Limit boxes 705 are fixedly connected to both the left and right ends of the front and rear walls of the tank 1. A limiting slot 706 is provided on the side wall of 705 near the limiting plug 704, which corresponds to the position of the limiting plug 704 and matches its specifications. Limiting grooves 707 are symmetrically provided at the upper and lower ends of the limiting slot 706. A fastening spring 708 is fixedly connected in the limiting groove 707, and a limiting clamping block 709 extending into the limiting slot 706 is fixedly connected to one end of the fastening spring 708 near the limiting slot 706. The shape of the second heat dissipation component 7 is relatively flexible, so it can not only ensure the unobstructed flow of the first heat dissipation hole 6 during normal use, but also seal and protect the first heat dissipation hole 6 when not in use, so that external dust and impurities are not easily allowed to enter the tank 1 through the first heat dissipation hole 6 and cause an impact.

[0027] Workflow: The tank 1 can transmit large currents, and its power distribution is convenient, maintenance is easy, safety and reliability are guaranteed, and it also saves space. The first heat dissipation component 2 can provide good heat dissipation for the tank 1, thus enabling the internal heat of the tank 1 to dissipate in a timely manner, preventing the internal structure from being affected by the inability to dissipate the internal heat in time. The internal heat of the tank 1 is transferred to the heat-conducting support plate 201 through the tank 1, and then to the heat dissipation fins 203 through the heat-conducting base 202. Finally, heat dissipation is achieved through heat exchange between the heat dissipation fins 203 and the outside air. The protective cover 3 can seal and protect the first heat dissipation component 2 when not in use to prevent external factors from affecting the first heat dissipation component 2. The snap-fit ​​component 4 can be used for the protective cover 3. The protective cover 3 provides good positioning capability with the first heat dissipation component 2, thus preventing displacement or falling off during protection and ensuring the protective effect of the protective cover 3 on the first heat dissipation component 2. When not in use, simply place the protective cover 3 on the outside of the first heat dissipation component 2, and then insert the positioning block 401 at its bottom into the positioning slot 402 on the heat conduction support plate 201 for positioning and locking. When in use, simply remove the protective cover 3. The connecting component 5 provides good connection capability between the first heat dissipation component 2 and the tank 1, thus ensuring the structural stability of the first heat dissipation component 2 during normal use and allowing for disassembly and replacement if the first heat dissipation component 2 is damaged, thereby facilitating later maintenance. When installing the first heat dissipation component 2, first place it on top of the tank 1, align the connecting bolt 502 on the connecting support plate 501 with the corresponding connecting screw hole 503, and finally screw the connecting bolt 502 into the connecting screw hole 503. Disassembly is similar. The first heat dissipation hole 6 provides good heat dissipation for the tank 1, allowing outside air to flow and exchange heat with the inside of the tank 1. Therefore, the internal heat of the tank 1 can be dissipated in a timely manner, preventing the internal structure from being affected by the inability to dissipate heat in time. The second heat dissipation component 7 has a more flexible shape, so it can not only ensure the unobstructed flow of the first heat dissipation hole 6 during normal use, but also seal and protect the first heat dissipation hole 6 when not in use, thus preventing damage. External dust and impurities enter the tank 1 through the first heat dissipation hole 6, causing an impact. During normal heat dissipation, the sliding support plate 702 is first slid to the right by the sliding support 701, so that the position of the second heat dissipation hole 703 corresponds to the position of the first heat dissipation hole 6. At this time, the first heat dissipation hole 6 is not blocked by the sliding support plate 702, so it can dissipate heat normally. At the same time, the right-side limiting block 704 will be inserted into the limiting slot 706 in the right-side limiting box 705. The insertion of the limiting block 704 will squeeze the limiting clamp 709 in the limiting slot 706, causing the limiting clamp 709 to move into the adjacent limiting clamp groove 707. At the same time, it will squeeze the fastening spring 708. The fastening spring 708 will then drive the limiting clamp 709 to reset through its own rebound force.This allows the two limiting clamps 709 to press against and position the right-side limiting block 704, preventing the sliding support plate 702 from sliding to the left due to failure to be positioned, which would cause the sliding support plate 702 to block the first heat dissipation hole 6. Similarly, when not in use, simply slide the sliding support plate 702 to the left using the sliding support 701 to close and block the first heat dissipation hole 6, and finally position it by inserting the left-side limiting block 704 into the left-side limiting box 705.
