Description

Technical Field

[0002] The existing bus ducts mainly include three types: fully enclosed bus ducts (such as dense bus ducts), cast bus ducts and air-type bus ducts. Since fully enclosed bus ducts and cast bus ducts are fully enclosed structures, they have the disadvantage of poor heat dissipation performance. Even if the fully enclosed bus duct increases the heat dissipation area through the aluminum shell, due to the fitting design of the internal conductive copper busbars, the heat dissipation efficiency of the internal copper busbars is much lower than the heat dissipation efficiency of the copper busbars on both sides, which easily causes the central temperature inside the bus duct to be higher; the air-type bus duct is an open bus duct structure with gaps between each copper busbar, but in order to improve insulation and safety, a thicker rubber insulation layer will be provided on the outer surface of the copper busbar, which seriously affects the heat dissipation efficiency of the copper busbar, and heat dissipation is only achieved through natural convection of air, which is difficult to effectively dissipate heat. Therefore, this application is based on the existing dense bus duct and air-type bus duct structures to improve and propose a silicone rubber composite insulation bus duct and a strong heat dissipation structure.

[0035] Example, by Figures 1 to 8 The present invention provides a silicone rubber composite insulated bus duct and a strong heat dissipation structure, comprising a support frame 1 and a split busbar assembly 2, the split busbar assembly 2 being snapped into the interior of the support frame 1, a plurality of strong cooling assemblies 3 being provided on one side of the support frame 1, and a plurality of strong cooling assemblies 2 4 being provided on the other side of the support frame 1, a plurality of strip support plates 5 being fixedly provided at the bottom end of the interior of the support frame 1, a plurality of cooling fans 6 being fixedly provided on the strip support plates 5, and the cooling fans 6 being located directly below the strong cooling assemblies 1 3 and 2 4, the split busbar assembly 2 being composed of a plurality of busbar units 7, a heat dissipation gap groove 8 being formed between two adjacent busbar units 7, and between the two outermost busbar units 7 and the inner side wall of the support frame 1, a temperature sensing cable 9 being provided at the top of the busbar unit 7, and a thermostat 10 being fixedly provided on the side of the support frame 1;

[0036] The busbar unit 7 is arranged separately and forms a heat dissipation gap groove 8, which can increase the contact area between the busbar unit 7 and the external air, thereby improving the heat dissipation efficiency. The heat dissipation fan 6 can blow air into the heat dissipation gap groove 8 to accelerate air convection, thereby achieving efficient convection heat dissipation. The temperature sensing cable 9 realizes comprehensive monitoring of the temperature of the busbar unit 7. When the temperature of a local area of ​​the busbar unit 7 is too high, the busbar unit 7 in the area is emergency heat dissipated. During emergency heat dissipation, liquid nitrogen is sprayed through the strong cooling component 1 3 and the strong cooling component 2 4, and the liquid nitrogen is dispersed by the heat dissipation fan 6. The liquid nitrogen evaporates to achieve efficient heat absorption of the busbar unit 7, thereby achieving efficient emergency heat dissipation, avoiding local overheating of the busbar unit 7 and fire.

[0037] The busbar unit 7 is composed of an aluminum alloy upper ferrule 11, an aluminum alloy lower ferrule 12, a copper busbar 13 and a composite insulation layer 14. The aluminum alloy upper ferrule 11 and the aluminum alloy lower ferrule 12 are respectively clamped to the top and bottom ends of the support frame 1. The copper busbar 13 is clamped between the aluminum alloy upper ferrule 11 and the aluminum alloy lower ferrule 12.

The aluminum oxide powder adhesion layer 17 is connected to the inner and outer surfaces of the silicone rubber layer 15 through the coupling agent layer 16 and fills the interior of the strip-shaped through-slots 18.

[0040] The heat of the copper busbar 13 can be transferred to the alumina powder adhesion layer 17, and then the heat is transferred to the aluminum alloy upper ferrule 11 and the aluminum alloy lower ferrule 12 through the alumina powder adhesion layer 17. The coupling agent layer 16 solidifies the alumina powder adhesion layer 17 and improves the thermal conductivity stability of the alumina powder adhesion layer 17. The silicone rubber thin layer 15 can improve the insulation performance, and the strip grooves 18 can transfer the heat.

[0041] The support frame 1 is composed of an L-shaped side support plate 19, an L-shaped side support plate 20, a plurality of clamping limit bottom plates 21 and a plurality of clamping limit top plates 22. The clamping limit bottom plate 21 and the clamping limit top plate 22 are respectively clamped to the bottom end and the top end of the L-shaped side support plate 19 and the L-shaped side support plate 20. The top end of the clamping limit bottom plate 21 and the bottom end of the clamping limit top plate 22 are both provided with a clamping groove 23 that matches the busbar unit 7. The clamping limit bottom plate 21 and the clamping limit top plate 22 are both connected to the L-shaped side support plate 19 and the L-shaped side support plate 20 by bolts 24. The L-shaped side support plate 19 and the L-shaped side support plate 20 are both provided with a plurality of strip-shaped heat dissipation grooves 25.

[0042] The L-shaped side support plate 19, the L-shaped side support plate 20, the plurality of clamping limit bottom plates 21 and the plurality of clamping limit top plates 22 realize the supporting and clamping functions, thereby improving the installation stability of the busbar unit 7. The strip-shaped heat dissipation grooves 25 can further improve the heat dissipation efficiency. The busbar unit 7 can be independently disassembled and installed through the independent clamping installation structure, thereby improving the convenience of repairing and maintaining the busbar unit 7 in the later stage.

[0043] The temperature sensing cable 9 is installed in an S-shaped structure at the top of the split busbar assembly 2, which can achieve comprehensive temperature measurement;

[0045] When the forced cooling components 1 3 and 2 4 are working, the solenoid valve 28 is opened, and the liquid nitrogen inside the liquid nitrogen tank 26 flows out or is dispersed in the form of steam. The main pipe 27 and the plurality of branch pipes 29 guide the liquid nitrogen. By cooperating with the cooling fan 6, the liquid nitrogen or low-temperature nitrogen gas can be diffused, and the evaporation of the liquid nitrogen or low-temperature nitrogen gas is used to achieve efficient heat absorption, thereby realizing emergency heat dissipation protection.

[0046] The aluminum alloy upper ferrule 11 is composed of a ferrule body 31, a strip cover plate 32 and several extended heat dissipation sleeves 33.

[0047] Heat is transferred to the aluminum alloy upper ferrule 11. At this time, the evaporative liquid 36 inside the U-shaped inner cavity 35 is evaporated by the heat to form steam. The steam carries the heat upward to the heat dissipation inner cavity 37, and heat is dissipated by extending the heat dissipation sleeve 33. The steam then condenses and flows back, forming a cycle of evaporative heat dissipation, thereby improving the efficiency of conventional heat dissipation of the bus duct.

[0050] During operation, by setting up multiple busbar units and setting up heat dissipation gap grooves between the busbar units, each busbar unit can form an independent structure, which can increase the contact area with the external air and thus improve the heat dissipation efficiency. By setting up a busbar unit composed of an aluminum alloy upper ferrule, an aluminum alloy lower ferrule, a copper busbar and a composite insulation layer, and setting up a heat dissipation fan, heat conduction heat dissipation can be achieved, and the heat convection efficiency can be improved, thereby further improving the heat dissipation efficiency.

By setting up a composite insulation layer composed of a thin silicone rubber layer, a coupling agent layer and an aluminum oxide powder attachment layer, and setting up a strip through groove, the insulation performance can be improved while also improving the thermal conductivity efficiency. The aluminum oxide powder attachment layer is reinforced by the coupling agent layer, and the heat can be transferred to the aluminum alloy upper ferrule and the aluminum alloy lower ferrule through the aluminum oxide powder attachment layer.
