1. A micro-channel heat exchanger, comprising two collecting pipes, a plurality of flat pipes and two side plates,
wherein the plurality of flat pipes and the two side plates are provided between the two collecting pipes, the two side plates are located at two outer sides of the plurality of flat pipes and defined as a first side plate and a second side plate, respectively; and
a plurality of fins are provided between the first side plate and one of the plurality of flat pipes adjacent to the first side plate, and between the second side plate and one flat pipe of the plurality of flat pipes adjacent to the second side plate, respectively,
a blocking part is further provided at an outer side of the first side plate and/or the second side plate and at a position close to one of the two collecting pipes, and the blocking part is capable of preventing a composite material on the collecting pipe from flowing towards a middle part of the first side plate and/or the second side plate,
the blocking part is spaced from the collecting pipe, and the blocking part and the corresponding first side plate and/or the second side plate are an integral structure,
wherein a complementary structure is defined by the blocking part at an inner side of the corresponding first side plate and/or the second side plate, and an end portion of one of the plurality of fins abuts against the complementary structure of the corresponding first side plate and/or the second side plate.
