Product Details

1. What It Is & What It Does

AESIMA Microchannel Heat Exchangers use flattened aluminum tubes with internal passages measuring just 1-2 mm in width, allowing refrigerant to flow through dozens of mini-channels in parallel. The result: dramatically more surface area in an incredibly small package. Vehicle air conditioning and modern heat pump systems rely exclusively on microchannel designs.
What it does: Multiple tiny parallel channels maximize refrigerant contact with tube surfaces while minimizing refrigerant charge volume (less fluid needed). Combined with fins, achieves extreme compactness.
Typical uses: Vehicle AC systems, heat pump condensers/evaporators, residential mini-split AC, commercial rooftop units,
automotive thermal management.Key specifications: design pressures 30-50 bar, temperatures -40°C to +150°C, with refrigerant charge 20-60% lower than traditional coils.

Microchannel Heat Exchanger micro-port parallel flow principle: isometric exploded view showing flat tube aluminum extrusion (16-25mm wide × 1.2-1.8mm thick rectangular profile) with internal micro-ports (10-20 parallel channels 0.5-1.5mm hydraulic diameter), louvered aluminum fins (0.08-0.12mm thickness with stamped louvers, 14-20 FPI) brazed to flat tubes, inlet/outlet aluminum manifolds with internal baffles distributing refrigerant, refrigerant (red) flowing through parallel micro-ports, ambient air (blue arrows) flowing perpendicular through louvered fins (cross-flow), micro-port internal structure detail inset (15-20 parallel channels with integral aluminum webs, high surface density 700-1,200 m²/m³, 30-50% less refrigerant), louvered fin air flow detail (louvers creating turbulence, 30-50% better heat transfer), side view showing stacked flat tubes with manifolds, 30-50% less refrigerant charge, CAB vacuum brazing, bottom comparison (microchannel flat tube 16mm×1.5mm with 15 micro-ports vs round tube 9.5mm OD single passage, microchannel advantage 2-3× surface density 50% less refrigerant)

uD83CuDF10 OEM Equipment	High-capacity chiller systems, district cooling loops	All Types	Integrate into OEM systems; minimal charge

Automotive Climate Control — Nearly all new vehicles (since 2010) use microchannel condensers. OEM preference for space/weight efficiency drives 100% market adoption.
Heat Pump Systems — Residential/commercial air-source heat pumps use microchannel designs for both heating and cooling cycles.Superior part-load efficiency.
Mini-Split AC Units — Compact indoor/outdoor units, wall-mounted or ceiling-cassette styles. Consumer preference for sleek appearance drives compact design.
Commercial Rooftop Units — Packaged HVAC units benefit from reduced footprint and weight. Installation on older buildings with load restrictions becomes possible.
Chiller Systems — Centrifugal/screw chiller condensers employ microchannel technology for efficiency and compactness.
Mobile Equipment — Portable cooling units, truck-mounted refrigeration, emergency response vehicles. Space constraints demand ultra-compact designs.
