Aluminum vapor deposition reflectors for LED lighting

As higher brightness levels are achieved for LEDs, Kansai Pipe has been developing reflectors for high-intensity LEDs employing aluminum coating.

Features

  • Aluminum is the only metal with a reflectivity of 90% or higher across a wide wavelength range.
  • Kansai Pipe’s vapor deposition line boasts the world’s fastest film forming speed.
  • Can be vapor deposited on any base material.

Applications

Ceramic, glass, metal, resin

Circulating flow type heat sinks (patent pending)

Employing our pipe fabrication technology, Kansai Pipe has been developing high-efficiency heat sinks.

Features

  • High performance
    Circulating flow can be expected to improve performance by approximately 8% to 10% compared to a fin type heat sink of the same size.
  • Lightweight
    Simply replacing a conventional fin type heat sink with circulating flow tubes can reduce weight up to 40%.
  • Design compatibility
    Cooling air escapes more easily than with a fin type heat sink, providing greater design freedom for tight spaces. With circulating flow there is almost no pressure loss.
  • Low noise
    The cross-sectional width reduces the airflow noise characteristic of fin type heat sinks.

Applications

Automobile radiators, heat sinks for laptop computers, exhaust heat recovery heat exchangers

Circulating flow type heat sinks

External resin parts for LCD TVs

High-strenght magnesium alloy pipe

Kansai Pipe has developed magnesium alloy pipe over 20% stronger than previous materials and boasting high dimensional precision.

Description

With a density less than 1/4 that of iron and approximately 2/3 that of aluminum, magnesium is the lightest of all metal structural materials. Magnesium alloys offer exceptional specific strength, vibration absorption, electromagnetic shielding performance and recyclability. Demand for these materials is growing, especially in the fields of mobile electronics and automobiles.
  Kansai Pipe has successfully developed high-strength magnesium alloy pipe that is stronger and tougher than previous extruded materials yet offers high dimensional precision.

Features

  • Tensile strength is improved by about 20% or more while maintaining the equivalent or greater ductility than previous extruded materials, achieving a tensile strength of 280 MPa for AZ31 alloy (containing 3% aluminum and 1% zinc) and 330 MPa for AZ61 alloy (containing 6% aluminum and 1% zinc).
  • Strength-enhanced pipe achieves a tensile strength of 380 MPa with AZ31 alloy.
  • Can be cold bended (pipe with an outer diameter of D = 21.5 mm and wall thickness of t = 1 mm can be bent to a minimum radius of R = 2.8D, approximately the same as for aluminum alloy).
  • Higher dimensional precision than previous extruded materials, maintaining the same level of precision as drawn aluminum material.
  • Pipe can be fabricated in outer diameters of 10 to 40 mm and wall thicknesses of 0.5 to 5 mm.
  • In addition to a round cross section, pipe can also be fabricated with an oblong, elliptical, or other irregularly shaped cross section.

Applications

High-strength magnesium alloy pipe is expected to be used in a wide range of applications, including medical goods such as wheelchairs and stretchers, in sporting goods such as bicycles and racquets, and also as a structural material for automobiles.

Circulating flow tubes have helical channels that produce a swirling flow of air. The effect of the resulting turbulent flow diminishes the boundary layer that prevents heat exchange. Circulating flow heat exchangers exploit this swirling flow effect.
