The utility model relates to the technical field of air conditioners, and discloses a micro-channel heat exchanger which comprises micro-channel flat pipes, fins and drainage grooves, and the leeward sides of the micro-channel flat pipes are obliquely arranged downwards in an arc shape so that condensate water can flow down along the leeward sides; the fins are provided with windows, and the ends of the windows face the micro-channel flat pipes so that condensate water of the fins can be guided to the micro-channel flat pipes. The drainage groove is formed in the leeward side of the micro-channel flat pipe and used for receiving condensate water flowing out of the micro-channel flat pipe and draining the condensate water. By the adoption of the micro-channel heat exchanger, when air flows through the micro-channel heat exchanger, heat exchange is conducted on the fin part, and condensate water is generated. In the windward section, condensate water flows to the arc-shaped section of the leeward side of the mi
