The invention discloses a micro-channel parallel flow evaporator, which relates to the technical field of air conditioning systems. The micro-channel parallel flow evaporator comprises an upper liquid collection tube component, a plurality of flat tubes arrayed uniformly, two end covers and a lower liquid collection tube, wherein two end surfaces of the upper liquid collection tube component are connected with the two end covers respectively, and two ends of each flat tube are connected with the bottom of the upper liquid collection tube component and the lower liquid collection tube respectively. By the invention, the uniform flowing of a refrigerant into each flat tube is guaranteed, the refrigerating capability and the air outlet temperature distribution uniformity of the evaporator are improved, the efficiency is improved, and the comfortableness is also improved.
