Abstract

A heat exchanger, a bent heat exchanger formed by bending the heat exchanger, and an air conditioning system having the heat exchanger or the bent heat exchanger. The heat exchanger includes: a plurality of rows of heat exchange tubes arranged in a first direction; and a plurality of fins arranged in a second direction perpendicular to the first direction. Each of the plurality of fins includes a fin body and a plurality of heat exchange tube slots formed in the fin body, one or more heat exchange tubes of each row of heat exchange tubes of the plurality of rows of heat exchange tubes being inserted into one heat exchange tube slot of the plurality of heat exchange tube slots; and a length of at least one heat exchange tube slot of the plurality of heat exchange tube slots of at least one fin of the plurality of fins in a third direction perpendicular to the first direction and the second direction is greater than a heat exchange tube size of the row of heat exchange tubes inserted into the at least one heat exchange tube slot in the third direction to form a gap for passage of water in the at least one heat exchange tube slot, thereby improving the performance of the heat exchanger, bent heat exchanger and air conditioning system.
