Title: MICRO-CHANNEL HEAT EXCHANGER AND AIR-COOLED REFRIGERATOR
Abstract:
Provided are a micro-channel heat exchanger (100) and an air-cooled refrigerator. The micro-channel heat exchanger (100) comprises two collecting pipes (1), a plurality of heat exchange pipes (2) and at least one fin (3), the two collecting pipes (1) being arranged parallel to each other. Two ends of the plurality of heat exchange pipes (2) are connected to the two collecting pipes (1) respectively, the plurality of heat exchange pipes (2) bend along the lengthwise direction thereof to form a plurality of pipe layers (20), and the flow resistance of a refrigerant in some of the heat exchange pipes (2) is lower than the flow resistance of the refrigerant in the remaining heat exchange pipes (2). Each fin (3) is arranged between two adjacent pipe layers (20) or on the outside of the outermost pipe layer (20), and each fin (3) extends in a corrugated form in the extension direction of the heat exchange pipes (2). Each fin (3) extends continuously in the extension direction of the collecting pipes (1). The fin (3) is provided with a ventilation hole (33).
