Microchannel Heat Exchangers: Engineered for Higher Efficiency
Microchannel heat exchangers(MCHE) are among the best choices for your high-efficiency heat transfer needs. Utilizing integral brazing technology between fins and flat-channel tubes, these heat exchangers feature thinner aluminum material with higher thermal conductivity, resulting in low thermal resistance and pressure drop. The flat tubes contain multiple microchannels, each providing ample contact with the coolant. This ensures uniform coolant flow, expands the heat transfer surface area, and delivers superior heat transfer efficiency.
Microchannel Heat Exchanger, the Cost-effective Option
Microchannel heat exchangers offer high cost-effectiveness, meeting your heat transfer needs while reducing expenses. The microchannel coil production process employs advanced brazing technology, resulting in a compact structure with high strength. Constructed entirely from aluminum, the product is lighter in weight, lowering transportation costs and preventing electrochemical corrosion between dissimilar metals, thereby indirectly extending its service life. Overall, microchannel heat exchangers typically reduce total costs by 5% to 30%.

Available Surface Treatment for Your Microchannel Heat Exchanger
Before surface treatment, microchannel coils typically undergo acid pickling pretreatment to remove surface oxide layers and impurities, followed by the application of a protective coating. Basic protection can be achieved through passivation, commonly using a trivalent chromium process (TCP) coating. E-coating is employed for high-salt spray and severe corrosion environments, while powder coating is used for certain products where aesthetics are a priority. Each surface treatment method extends the service life of microchannel coils to varying degrees.
