The uneven distribution of refrigerants is a key issue in outdoor heat exchanger research.In this study, two types of baffles were designed, and a total of seven samples were prepared and placed in the heat exchanger header for experimental research.Through experiments, the refrigerant distribution and heat transfer performance of the six working conditions of the heat exchanger as an evaporator and whelen arges spotlight the four working conditions of the condenser were analyzed.The results show that using baffles achieves a good refrigerant distribution effect, and the addition of two baffles (A and B) can help improve the uneven distribution of the refrigerant in the heat exchanger and improve the heat transfer performance.In addition, the type and number of baffles and the position of the inlet and outlet of the heat exchanger have an impact on the heat transfer performance.

When the heat exchanger is used as an evaporator, the increase in the number of baffles increases the refrigerant capacity of baffle A by 15.28% and baffle B by 10.87%, reducing the pressure drop of baffle A by 26.07% and baffle B by 58.82%.

The rise in the inlet and outlet positions reduces the pressure drop of baffle A by 55.56% and increases the refrigerant capacity by 12.81%.The downward movement reduces the pressure drop of baffle A by 55.56% and baffle B by 130% and increases the refrigerant capacity of baffle A by 13.

42% and baffle B by 4.84%.When used as a condenser, the increase in the inlet and outlet positions reduces the pressure drop of baffle A by 16.67% and baffle B by 27.03% and increases the refrigerant capacity of baffle A by sheepshead bay boats 4.

72% and baffle B by 3.9%.
