Description

Technical Field

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

[0002] Cast-in-place busbar trunking is a new type of metal-free busbar trunking with four protective functions: waterproof, fireproof, corrosion-proof, and explosion-proof. It is suitable for various harsh and high-cleanliness environments and is widely used in shipbuilding, papermaking, power plants, substations, petrochemicals, steel metallurgy, machinery and electronics, and large-scale construction. However, existing cast-in-place busbar trunking cools down slowly after casting, mostly relying on natural heat dissipation, which results in a long casting cycle and reduced work efficiency.

[0003] For example, patent CN221584252U describes a mold for casting busbar trunking, including a casting groove with notches on both sides. A baffle plate is detachably connected at each notch to seal the notch. The baffle plate has a through-slot for accommodating and fixing copper busbars. A guide plate is symmetrically fixed to the side of the through-slot away from the casting groove, with a gap between the guide plate and the copper busbar. This invention solves the risk of short circuits in the copper busbars that exists in traditional busbar trunking casting. However, after casting, the above device has a slow heat dissipation rate, failing to cool down quickly and reducing its operating efficiency.

[0004] Based on this, a fast heat dissipation busbar casting mold is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a fast heat dissipation busbar casting mold to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

A casting cavity is formed at the top of the casting mold, and baffles are movably connected to the left and right sides of the inner wall of the casting cavity. The top of the baffles is threadedly connected to the outer surface of bolts. Through grooves are evenly distributed on one side of the baffles, and copper busbars are inserted into the inner walls of the through grooves. The middle part of the copper busbars is located in the inner cavity of the casting cavity. A cooling mechanism is provided at the lower right side of the casting mold.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0009] In an alternative embodiment, the width of the inner cavity of the through groove near the baffle is greater than the width of the copper bar, and the width of the inner cavity of the through groove far from the baffle is adapted to the width of the copper bar.

[0010] In an alternative embodiment, the shape of the copper bar is an inverted "convex" shape.

[0011] In an alternative embodiment, the inner cavity of the pouring cavity and the outer wall of the baffle are both coated with epoxy resin release agent.

[0012] In an alternative embodiment, the cooling mechanism includes a shunt pipe. Three dust-proof grille plates are fixedly connected to the left part of the shunt pipe in a linear array. A heat dissipation fan is fixedly connected to the right side of the shunt pipe. The output end of the heat dissipation fan is fixedly connected to an air duct. The left part of the air duct penetrates through the outer wall of the shunt pipe and extends into the inner cavity of the shunt pipe. The left side surface of the shunt pipe is evenly distributed with air inlet pipes. The left side of the air inlet pipe is fixedly connected to the right side of the pouring mold. An air inlet is provided on the inner wall of the air inlet pipe. A cooling air duct is provided on the left part of the air inlet. The cooling air duct is opened at the bottom of the pouring mold.

[0015] In an alternative embodiment, the heat sink assembly is composed of a plurality of heat sinks, and the gaps between the plurality of heat sinks are interconnected with the air inlet.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] Through the cooperation among the heat dissipation fan, the air duct, the air inlet pipe, the air inlet, the cooling air duct and the heat sink assembly, the present utility model achieves the purpose of increasing the air flow rate, making the air flow faster after entering the cooling air duct, so as to take away the heat on the heat sink assembly faster and achieve the purpose of rapid heat dissipation and cooling.

Specific embodiments

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, as Figures 1-3 shown, a busbar pouring mold capable of rapid heat dissipation includes a pouring mold 1. Bolts 11 are threadedly connected to the tops of both left and right sides of the pouring mold 1. A pouring cavity 14 is opened at the top of the pouring mold 1. A baffle 12 is slidably connected to the inner wall of the pouring cavity 14 through a guide rail, and the top of the baffle 12 is fixed by a bolt 11. A plurality of through grooves 13 are evenly distributed on one side of the baffle 12. A copper row 15 is inserted into the inner wall of the through groove 13. The middle part of the copper row 15 is located in the inner cavity of the pouring cavity 14. A cooling mechanism 2 is provided at the lower right side position of the pouring mold 1;

[0025] In this embodiment, the baffle 12 is placed into the pouring cavity 14 in the pouring mold 1, and then the baffle 12 is fixed by a bolt 11. Then, both ends of the copper row 15 are placed into the inner cavity of the through groove 13, and at the same time, the middle part of the copper row 15 is located in the inner cavity of the pouring cavity 14. After the preliminary work is completed, epoxy resin is poured into the pouring cavity 14;

[0026] In one embodiment, as Figure 1 and Figure 3 shown, the width of the inner cavity of the through groove 13 near the baffle 12 is greater than the width of the copper row 15, and the width of the inner cavity of the through groove 13 far from the baffle 12 is adapted to the width of the copper row 15. Among them, when pouring epoxy resin into the pouring cavity 14, a part of it flows into the through groove 13 through the gap between the through groove 13 and the copper row 15, so as to wrap the copper row 15 near the baffle 12 and form an insulating layer.

[0027] In one embodiment, as Figure 2 shown, the outer shape of the copper row 15 is an inverted "convex" shape. The specific outer shape makes the copper row 15 not slide left and right after being placed into the pouring cavity 14, which is convenient for shaping.

[0028] In one embodiment, as Figure 1As shown, the inner cavity of the casting cavity 14 and the outer wall of the baffle 12 are both coated with epoxy resin release agent. Applying epoxy resin release agent to the inner cavity of the casting cavity 14 and the outer wall of the baffle 12 facilitates the subsequent demolding of the already shaped busbar trunking and prevents epoxy resin from sticking to the casting cavity 14 and the baffle 12.

[0029] In one embodiment, such as Figure 2 and Figure 4 As shown, the cooling mechanism 2 includes a distribution pipe 21. Dustproof grilles 211 are evenly distributed inside the left side of the distribution pipe 21. A cooling fan 22 is fixedly connected to the right side of the distribution pipe 21. An air duct 23 is fixedly connected to the output end of the cooling fan 22, penetrating the side wall of the distribution pipe 21 and communicating with its inner cavity. Air inlet pipes 24 are evenly distributed on the left surface of the distribution pipe 21. The left side of the air inlet pipes 24 is fixedly connected to the right side of the casting mold 1. An air inlet 25 is provided on the inner wall of the air inlet pipes 24. A cooling air duct 26 is provided on the left side. The cooling air duct 26 is opened at the bottom of the casting mold 1. Multiple heat sink assemblies 27 are fixedly connected in a linear array on the inner wall of the cooling air duct 26. By starting the cooling fan 22, air is blown into the distribution pipe 21 through the air duct 23. The dustproof grid 211 in the distribution pipe 21 blocks larger particles in the air. Then the air enters the air inlet 25 and is transported to the cooling air duct 26 to remove the heat from the heat sink assembly 27.

[0030] In one embodiment, such as Figure 2 and Figure 4 As shown, the air inlet 25 is shaped like a trumpet, with the left side smaller than the right side. When air enters from the larger end of the air inlet 25 and exits from the smaller end, the air pressure is increased, thereby increasing the airflow speed.

[0031] In one embodiment, such as Figure 2 As shown, the smaller hole on the left side of the air inlet 25 is connected to the cooling air duct 26, and the larger hole on the right side of the air inlet 25 is connected to the dustproof grille 211 and the diversion pipe 21. The dustproof grille 211 blocks larger particles in the air, preventing them from entering the air inlet 25 and the cooling air duct 26.

[0032] In one embodiment, such as Figure 2 As shown, the heat sink assembly 27 is composed of multiple heat sinks, and the gaps between the multiple heat sinks are connected to the air inlet 25. When the air enters the cooling air duct 26 through the air inlet 25, it quickly carries away the heat on the heat sink assembly 27, thereby accelerating the heat dissipation rate of the heat sink assembly 27.

[0033] The above embodiment discloses a fast-heat dissipating busbar casting mold. During busbar casting, a baffle 12 is placed into the casting cavity 14 within the casting mold 1, and then fixed with bolts 11. Next, both ends of the copper busbar 15 are placed into the inner cavity of the through-slot 13, with the middle portion of the copper busbar 15 positioned within the inner cavity of the casting cavity 14. After this preliminary work, epoxy resin is poured into the casting cavity 14. A portion of the epoxy resin entering the casting cavity 14 flows into the through-slot 13 through the gap between the through-slot 13 and the copper busbar 15, thus wrapping the copper busbar 15 near the baffle 12 to form an insulating layer, preventing short circuits between the copper busbars 15. When the epoxy resin casting is complete and setting is required, the upper casting portion of the mold is sealed, and then the cooling fan 22 is activated, discharging air through the air duct 23. Air is blown into the distribution pipe 21, where the dustproof grille 211 blocks larger particles. The air then enters the air inlet 25, which transports it to the cooling duct 26. The shape of the air inlet 25 increases the airflow velocity, allowing the air to carry away heat from the heat sink assembly 27 more quickly. This increases the heat dissipation speed, enabling the epoxy resin-cast busbar in the casting cavity 14 to cool and solidify faster, resulting in rapid heat dissipation. In summary, by sending air into the distribution pipe 21 via the cooling fan 22, and by accelerating airflow through the air inlet 25, the airflow velocity within the cooling duct 26 is increased, allowing for faster heat removal from the heat sink assembly 27 and improved heat dissipation efficiency.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
