Abstract：Through comparative experiments,analyze the heat transfer performance,overall capacity and energy efficiency of all-aluminum microchannel heat exchangers and copper tube aluminum fin heat exchangers.The results indicate that the whole machine equipped with an all-aluminum heat exchanger has significant advantages in terms of capacity and energy efficiency,but its capacity decays severely under low-temperature heating conditions,the problem of uneven flow separation still needs further improvement.
