Abstract
In experimental air flow conditions, the effects of inner structure on the heat transfer and flow characteristics of micro-channel parallel flow type evaporator are investigated. The results indicate when the deflector in front of the evaporator outlet is removed, the cooling capacity in different air flow is increased by 9.59% ~ 10.56% than the original evaporator, and the resistance coefficient is reduced about 12. 5%, thus the evaporator performance is improved significantly in different conditions. While the circulation area of the connections between the two flow processes is increased on the basis of the above, there is no influence on the pressure drop of evaporator, but the cooling capacity is reduced significantly. So the evaporator performance is decreased. When increasing the inner circulation area of manifold, the different position of the circulation area produces different impact on the refrigeration capacity of the evaporator. In the condition of flow distribution of refrigerant being not decreased, the increase of circulation area can decrease the pressure drop and improve cooling capacity.关键词
