Definitions

  • Micro channel heat exchangers MCHXs and their alloys of construction were developed for automotive applications. Initial applications of these alloy systems resulted in poor corrosion performance, however, in heating, ventilation and air conditioning (HVAC) applications, such as roof top chillers. This problem is especially pronounced in coastal and/or industrial environments, where deterioration of the MCHX tubing can result in refrigerant leaks and system shutdown within a year. In addition, in coastal locations, fin disbonding due to corrosion effects may be a significant problem.
  • HVAC heating, ventilation and air conditioning
  • FIG. 4 is a perspective view of a manifold of the MCHX of FIG. 1.
  • This invention involves aluminum micro channel heat exchanger (MCHX) alloy systems including multi-channel (or multi-port) extruded tubes, with or without sacrificial anodic surface treatments, such as zinc, fin alloys cladded with a silicon rich lower melting point layer, a manifold (or header) alloy and a brazing flux.
  • MCHX micro channel heat exchanger
  • the tube 40 includes at least one of 31108 alloy material (especially with lithium flux), which includes 0.21-0.25 wt% silicon, 0.12 wt% iron, 0.01 wt% copper, 0.90-1.10 wt% manganese, 0.05 wt% magnesium, 0.02 wt% chromium, 0.03 wt% zinc and 0.14-0.20 wt% titanium, 31107 alloy material and 31104 alloy material, which includes 0.10 wt% silicon, 0.01 wt% copper, 0.05 wt% magnesium, 0.05 wt% zinc, 0.12 wt% iron, 1.10 wt% manganese (or magnesium), 0.05 wt% chromium and 0.05 wt% titanium, and extends from the first manifold 20 to the second manifold 30.
  • 31108 alloy material especially with lithium flux
  • the tube 40 may be plural in number with each of the plural tubes 40 extending from the first manifold 20 to the second manifold 30.
  • Each of the plural tubes 40 is also formed to define multiple channels 41.
  • the tube 40 may have a non-circular cross-section, such as an elongate cross-section, with the multiple channels 41 being arrayed along the non-circular cross-section.
  • the multiple channels 41 would be arrayed along the elongations of the tube 40.
  • the fin structure 50 may also be plural in number with each of the plural fin structures disposed in thermal communication with the tube(s) 40.
  • the fin structures 50 may include louvers 52 arranged along a longitudinal length of the tube(s) 40 to increase fin structure surface area and, therefore, heat transfer.
