Microchannel heat exchanger
Microchannel Heat Exchanger (MCHE) is a compact heat exchanger with hydraulic diameter of heat transfer channels ≤1 mm (10–1000 μm). It is composed of porous flat tubes, headers and louver fins. Fluids flow inside micro-scale channels to achieve high-efficiency heat transfer.

Core Structure
Porous Flat Tubes：Contain dozens of parallel microchannels; standard dimensions: thickness 1.6–2 mm × width 16–25 mm, channel equivalent diameter 0.5–1 mm.
Headers：Connect both ends of flat tubes, with internal baffles for multi-pass flow distribution to guarantee uniform medium distribution.
Fins：Mainly louver type with fin pitch 1.2–2.5 mm, enhancing air-side heat transfer and structural rigidity.
Printed Circuit Heat Exchanger (PCHE)：Adopts chemically etched microchannels bonded by diffusion welding, resistant to high temperature and high pressure, applied in extreme working conditions such as chemical industry, nuclear power and hydrogen energy.
Core Advantages
High Efficiency & Compact Size：Large specific surface area and thin thermal boundary layer; heat transfer efficiency is 2–5 times higher than conventional exchangers, with volume reduced by 30%–60%.
Lightweight & Low Refrigerant Charge：Light weight and low refrigerant filling volume, meeting space and energy efficiency demands of vehicle, airborne and precision equipment.
High Pressure & Temperature Resistance：Aluminum alloy versions withstand 4–10 MPa; PCHE can operate under extreme conditions up to 60 MPa and 900℃.
Precise Temperature Control：Small temperature difference (≤3 K) and fast thermal response, ideal for electronic cooling, biomedicine and fine chemical processes.
Materials & Weight
Main Materials：Conventional: 3003 aluminum alloy，High-pressure service: 5052 aluminum alloy，Corrosion-resistant service: stainless steel / titanium alloy
Weight Performance：30%–70% lighter than copper tube-aluminum fin heat exchangers; refrigerant charge reduced by over 50%.
