Abstract: A heat exchanger and an air conditioning system having the same. The heat exchanger includes a plurality of fins and a row of heat transfer tubes. The fin includes a fin body and a plurality of columns of heat exchange tube slots formed in the fin body. The column of heat exchange tube slots includes a plurality of heat exchange tube slots arranged in a first direction, the plurality of fins being arranged in a second direction perpendicular to the first direction, and the plurality of columns of heat exchange tube slots being arranged in a third direction perpendicular to the first direction and the second direction. The row of heat exchange tubes is provided in the heat exchange tube slot of the column of heat exchange tube slots, and the row of heat exchange tubes includes one heat exchange tube or a plurality of heat exchange tubes. A length of at least one heat exchange tube slot in the third direction is greater than a heat exchange tube size of the row of heat exchange tubes inserted in the at least one heat exchange tube slot in the third direction. Therefore, the performance of the heat exchanger and the air conditioning system can be improved.

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.
