Definitions
- the present invention relates to a high performing aluminium component such as busbars and other electrical conductors and heat sinks with a surface coating suitable for thermal radiation, a method for preparation and application of the coating on the components.
- the current rating of a busbar is limited by the maximum ambient temperature and the maximum permitted working temperature.
- heat is generated in the bar due to the electrical resistance, and the heat is evacuated or tapped from the bar by convection and radiation.
- an alloy with reduced electrical resistivity in combination with a high emissivity coating will improve the performance of electrical conductors.
- performance may be increased by providing ribs, corrugations or other surface modifications which enhances convection and thereby increase heat transfer. The result should be the smallest possible bar size. As energy costs rise, it is worth considering the lifetime cost of a busbar system, including capital cost and the cost of waste energy.
- Aluminium can substitute copper in many new application for electrical conductors.
- the increased copper prize increase the market pull for aluminium conductors and busbars.
- busbars thermal conductivity is very important due to the maximum limit on operational temperature.
- General known requirements as regards he maximum temperature limits for bus bars are in the range of 140 and 105°C.
- a high performing aluminium component suitable for thermal radiation applications such as aluminium busbars or heat sinks with high emissivity.
- Fig. 3 shows an alternative bus bar design with serrated surface in the form of longitudinal ribs.
- Standard black powder coating typically has an emissivity from 0.84 to 0.88.
- the emissivity is influenced by the binder system, pigmentation and the surface roughness. As is indicated above, black matt coatings have higher emissivity then black and glossy surfaces.
- the pigmentation of a black powder coating for interior applications can apply all types of pigments and binder systems since it is not affected by solar radiation or corrosive environment.
- the coating may be a dry powder coating type or wet type coating containing black pigments.
- the coating may be a thermosetting or thermoplastic polymer such as polyester or polyurethane, polyester epoxy, straight epoxy or acrylics.
- the coating may be any polymer based type such as an acrylic polymer coating, polyester resin type or polyurethane type.
- Figs. 1 and 2 shows respectively in perspective view and cross section, a busbar 1 of aluminium with a coating 2 according to the invention.
- the aluminium busbar is preferably made by extrusion of an age hardening 6000 aluminium alloy with high electrical conductivity and yield strength in the range from 100 to 180MPa.
- EC 6000 and EC 1000 each containing by weight %:
- the electrical conductivity can be increased by reducing the content of elements like Fe, Cu, Mn, Cr, Zn, Ti and V in a standard 6101 aluminium alloy and the above selected alloy lies within the desired electrical conductivity level.
- Such process may include the following process steps:
- the busbar will be held or stored at required temperature for some time to cure (dry or harden etc.) the coating.
- the tape will then finally removed after the coating has been cured / dried. .
- a temperature rise test has documented that the total effect of the selected alloy and use of the high emissivity black powder according to the invention was -10°K, or 7% performance improvement.
- Fig. 3 shows an alternative bus bar 5 where performance is increased by providing ribs 6, which enhances convection and thereby increase heat transfer.
- Other designs may also be provided such as corrugations, dents or other surface modifications.
- the bus bar may as well, as in the former example shown in Figs. 1 and 2 be provided with an uncoated part 7 in the longitudinal or transversal direction.
