[0030] 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.
[0031] Example 1: Please refer to Figures 1 to 10This utility model provides a technical solution: a waterproof busbar trunking shell structure, including a main busbar trunking shell 1, a heat dissipation mechanism 2 on the outer side of the main busbar trunking shell 1, a busbar body 10 installed inside the main busbar trunking shell 1, a positioning partition 15 on the outer side of the busbar body 10, the main busbar trunking shell 1 including a mounting top plate 11 and a heat dissipation side plate 12, the heat dissipation side plate 12 being fixed to the mounting top plate 11 by bolts, corrugated protrusions 13 being provided on the surfaces of both the heat dissipation side plate 12 and the mounting top plate 11, a sealing strip 14 being installed at the end of the heat dissipation side plate 12, one side of the sealing strip 14 being attached to the inner wall of the mounting top plate 11, thus... The mounting top plate 11 is fixed to the outside of the heat dissipation side plate 12 by bolts and sealed by the sealing strip 14. At the same time, the positioning and sealing are enhanced by the interlocking of the corrugated protrusions 13. The corrugated protrusions 13 on the mounting top plate 11 and the heat dissipation side plate 12 are the same size and are connected by the corrugated protrusions 13. During use, the mounting top plate 11 and the heat dissipation side plate 12 are more stable and the corrugated protrusions 13 can enhance the seal. Sealing grooves are provided on both ends of the heat dissipation side plate 12, and the sealing strip 14 is installed inside the sealing grooves to ensure that the sealing strip 14 is more stable during use.
[0032] As can be seen from the above description, the present invention has the following beneficial effects: during use, the corrugated protrusions 13 and the sealing strip 14 strengthen the sealing at the connection between the mounting top plate 11 and the heat dissipation side plate 12, thereby ensuring a better sealing effect during installation and use, and preventing leakage after installation and pouring and during subsequent use.
[0033] Further reading is available. Figures 1 to 10Both the mounting top plate 11 and the heat dissipation side plate 12 are fitted with reinforcing ribs 121. One side of the heat dissipation side plate 12 passes through the heat dissipation side plate 12 and intersects with the reinforcing ribs 121. The heat dissipation side plate 12 includes a heat-conducting outer shell 122 and a heat-conducting inner core 123 installed inside the heat-conducting outer shell 122. The reinforcing ribs 121 are inserted into the inner side of the heat-conducting inner core 123. The reinforcing ribs 121 strengthen the mounting top plate 11 and the heat dissipation side plate 12, and cooperate with the heat-conducting outer shell 122 and the heat-conducting inner core 123 to ensure heat conduction when heat is dissipated outward through the heat sink 21. The positioning partition 15 is provided with sealing buffer sleeves 151 on both the outer and inner sides. The positioning partition 15 is installed by fitting the sealing buffer sleeves 151 through the inner hole. On the outside of the busbar body 10, the positioning partition 15 is tightly attached to the inside of the main housing 1 of the busbar trunking through the sealing buffer sleeve 151. The positioning partition 15 and the sealing buffer sleeve 151 separate the inside of the main housing 1 of the busbar trunking. Together with the heat-conducting inner box 22 and the heat-conducting pipe 23, the busbar body 10 in the separated space is cooled quickly. The two sides of the mounting top plate 11 are integrally formed with the mounting main frame 111. The inner side of the mounting top plate 11 is fitted and fixed with the buffer pad 112. The mounting main frame 111 and the buffer pad 112 provide locking support for the mounting frame. The locking support of the mounting main frame 111 and the buffer pad 112, together with the elastic shock absorption of the buffer pad 112, ensures greater stability during installation and use.
[0034] Example 2: Please refer to Figures 1 to 10 As shown, based on Embodiment 1, this utility model provides a technical solution: the heat dissipation mechanism 2 includes a heat sink 21 mounted on the surface of the heat dissipation side plate 12 and a heat conduction pipe 23 mounted on the busbar body 10. A heat conduction inner box 22 is installed inside the heat dissipation side plate 12, with both ends of the inner box 22 communicating with both ends of the heat conduction pipe 23. The surface of the heat sink 21 is provided with heat dissipation protrusions 24, and one end of the heat sink 21 is provided with a heat conduction frame 25, which is installed inside the heat conduction inner box 22. The heat conduction pipe 23 is spirally wound around the outside of the busbar body 10, and the heat conduction pipe 23... The busbar body 10 generates heat by screwing quick connectors onto the two ends of the heat-conducting inner box 22. The heat is absorbed by the heat-conducting pipe 23 and the internal heat-conducting medium. The heat-absorbing medium flows under pressure into the heat-conducting inner box 22 and works with the heat-conducting frame 25 and the heat-conducting inner box 22 to quickly conduct heat to the heat dissipation side plate 12 and heat sink 21. The heat-conducting pipe 23 includes a conduit body 231. The inner wall of the conduit body 231 is provided with heat-conducting capillary protrusions 232. Heat-conducting ribs 233 are installed on the inner side of the conduit body 231. Together with the heat-conducting inner box 22 and the heat-conducting pipe 23, the busbar body 10 in the partition space is quickly cooled down.
[0035] Using the above technical solution, during use, the heat-conducting pipe 23 is wrapped around the outside of the bus body 10. When the bus body 10 dissipates heat, the heat is absorbed by the heat-conducting pipe 23 and the internal medium. After absorbing heat, the medium expands and flows into the heat-conducting inner box 22. The heat is then conducted to the heat dissipation side plate 12 and heat sink 21 through the heat-conducting inner box 22 and the heat-conducting frame 25, thereby accelerating heat dissipation.
[0036] The working principle and usage process of this utility model are as follows: During assembly, the heat pipe 23 is first installed on the bus body 10, and the positioning partition 15 is sleeved on the bus body 10 to separate the heat pipes 23. Then, it is installed between the heat dissipation side plates 12. One end of the heat pipe 23 is screwed onto the end interface of the heat-conducting inner box 22 through a quick connector, and a heat-conducting medium is introduced into the heat-conducting inner box 22 and the heat pipe 23. Then, the mounting top plate 11 is fixed to the outside of the heat dissipation side plate 12 with bolts and sealed with a sealing strip 14. At the same time, the positioning and sealing are strengthened by the interlocking between the corrugated protrusions 13. When in use, the heat generated by the bus body 10 is absorbed by the heat pipe 23 and the internal heat-conducting medium. The heat-absorbing medium flows into the heat-conducting inner box 22 under pressure. With the help of the heat-conducting frame 25 and the heat-conducting inner box 22, heat is quickly conducted and dissipated to the heat dissipation side plate 12 and the heat sink 21. With the help of the heat dissipation protrusions 24, heat dissipation can be accelerated.
[0037] During use, the mounting frame is secured by the main frame 111 and the buffer pad 112, and the elastic shock absorption of the buffer pad 112 ensures greater stability during installation and use. The main housing 1 of the busbar trunking is divided by the positioning partition 15 and the sealing buffer sleeve 151. The busbar body 10 in the divided space is quickly cooled by the heat-conducting inner box 22 and the heat-conducting pipe 23. The strength of the mounting top plate 11 and the heat dissipation side plate 12 is strengthened by the reinforcing ribs 121. When heat is dissipated outward through the heat sink 21, the heat-conducting outer shell 122 and the heat-conducting inner core 123 ensure heat conduction. When the heat-conducting pipe 23 absorbs heat from the busbar body 10, the heat-conducting capillary protrusions 232 and the heat-conducting ribs 233 accelerate the heat conduction to the internal medium, thereby quickly absorbing heat and cooling the busbar body 10.
