Abstract: The present disclosure provides a micro-channel heat exchanger including two collecting pipes, and a plurality of flat pipes and two side plates that are arranged between the two collecting pipes, wherein the two side plates are located on two outer sides of the flat pipes and are defined as a first side plate and a second side plate respectively; fins are respectively arranged between the first side plate and the adjacent flat pipe and between the second side plate and the adjacent flat pipe; and the outer side of the first side plate and/or the second side plate is provided with a blocking part at a position close to the collecting pipe, and the blocking part can prevent composite material on the collecting pipe from flowing to a middle part of the first side plate and/or the second side plate.

Abstract: The invention involves a micro-channel heat exchanger, which includes flat tubes (8), fins (9) and plate-type header pipes communicated with the flat tubes, (8) each plate-type header pipe comprising a flat tube groove plate, a distribution plate (2) and an outer side sealing plate (5), a plurality of flat tube groove through holes (3) are provided in the flat tube groove plate (1) along a length direction, throttling channels (4) communicated with the flat tube groove through holes (3) are provided in the distribution plate (2) along an arrangement direction of the flat tube groove through holes (3), the outer side sealing plate (5) is provided on one side, far away from the flat tube groove plate (1), of the distribution plate (2). The micro-channel heat exchanger can solve the problems of low heat exchange efficiency and small heat exchange area of the heat exchanger.
