<p>Disclosed is a heat exchanging device which is provided with: a heat exchanger (15), which has a plurality of heat transfer tubes (24) wherein a refrigerant circulates, and which functions as an evaporator; a plurality of connecting tubes (27) which are connected to respective heat transfer tube (24) end portions on the refrigerant discharge side; and a header (28), which is connected to the connecting tube (27) end portions on the refrigerant discharge side, and which joins together the refrigerant discharged from the connecting tubes (27). At least some of the connecting tubes (27) are composed of flow channel-expanded connecting tubes (27) wherein the flow channel cross-section area on the header (28) side is formed larger than the flow channel cross-section area on the heat transfer tube (24) side.</p> |
