Title: HEAT EXCHANGER AND AIR CONDITIONER
Abstract:
A heat exchanger and air conditioner are provided which, while sufficiently guiding a refrigerant even to flat tubes positioned above, and while avoiding increased size and decreased performance, can minimize drift of refrigerant between the multiple flat tubes. This heat exchanger is provided with multiple flat, multi-hole tubes (63) provided one above the other, a second header collector (90) to which the multiple flat multi-hole tubes (63) are connected, a first connection piping (24) connected to the second header collector (90), and a nozzle (71a) through which refrigerant is fed upwards from the inlet space (97) when used as an evaporator, wherein the nozzle (71a) is positioned towards the flat multi-hole tube (63) with respect to the first connection piping (24), and the inlet space (97) is configured such that the space below the nozzle (71a) is narrower in the vertical direction than the space where the first connection piping (24) is connected.
