Low Noise Cooling From 10 Watts/°C TO 20 Watts/°C

  • A patent pending passive sealed enclosure cooler design consisting of a smaller, high performance aluminum finned heat sink and a larger, extruded aluminum heat sink bonded to the opposite sides of a common mounting plate
  • The smaller heat sink side has a dedicated fan impinging hotter air inside the enclosure onto the heat sink
  • The larger, extruded heat sink side has no fans (LNC-10) or ultra-low power fans (LNC-20) for quiet, natural convection (with fan assistance as in the LNC-20 case) heat dissipation to the outside ambient
  • Multiple heat pipes are embedded in the mounting plate, efficiently spreading heat from the smaller heat sink side to the larger heat sink side
  • “Thin profile”, i.e., only 3.70″ intrusion into the enclosure
  • Similar to the HSC series: dual axial ball bearing fans for years of maintenance free operation, Rugged high quality construction, ease of installation, and a minimum number of penetrations by cover fasteners, mounting fasteners or external fan wires
