The present disclosure relates to a heat exchanger and an air conditioner improving heat exchange ability by optimizing the number of high protrusions of a heat transfer tube and a height difference between the high protrusion and a low protrusion to increase the heat transfer performance of the heat transfer tube or reduce the pressure loss in the tube. An air conditioner includes the heat exchanger including a heat transfer tube configured to allow the refrigerant to flow, fins installed on the heat transfer tube, and fin collars forming an insertion hole through which the heat transfer tube is inserted and passes, and the fin collars is in contact with the heat transfer tube by tube expansion of the heat transfer tube. The heat transfer tube includes high protrusions disposed in a spiral shape with respect to a tube axis direction of the heat transfer tube, twenty one to twenty seven of the high protrusions being formed along a circumferential direction of the heat transfer tube, and low protrusions disposed between two of the adjacent high protrusions along the circumferential direction of the heat transfer tube and having a height lower by 0.03 mm to 0.05 mm than the high protrusions.

A heat exchanger assembly has a frame including: a plurality of legs; first and second lower transversal members extending perpendicular to and interconnecting the legs; a plurality of upstanding members extending upwardly from respective ones of the legs, a lower end of each upstanding member being connected to a corresponding leg at a junction therebetween; an upper transversal member interconnecting upper ends of the upstanding members; and an upper frame assembly. The frame components are weldlessly connected to one another. First and second heat exchanger panels exchange heat with air pulled into the heat exchanger assembly and are disposed in a V-configuration. An upper end of each heat exchanger panel is connected to upper retaining members of the upper frame assembly. A fan pulls air into the enclosed space of the heat exchanger assembly via at least one of the heat exchanger panels.
