Heat exchanger unit and air-conditioning apparatus

A heat exchanger unit comprising:

• a heat exchanger;
• a drain pan provided below the heat exchanger;
• and
• a housing that houses the heat exchanger and the drain pan and that has an inlet side surface and an outlet side surface opposite to the inlet side surface, the heat exchanger being disposed between the inlet side surface and the outlet side surface, the inlet side surface having an open inlet from which air flows into the heat exchanger, the outlet side surface having an open outlet from which air that has undergone heat exchange flows out, wherein:
• the drain pan is a pullout drain pan capable of being pulled out sideways from the housing,
• a dew dripping space is formed between the heat exchanger and the outlet side surface of the housing, and in the dew dripping space, dew formed at the heat exchanger and blown off by an air flow drips into the drain pan due to its own weight before reaching the outlet,
• the heat exchanger unit further includes a fixing component by which the heat exchanger is fixed to the outlet side surface of the housing without interfering with lateral movement of the drain pan and that forms the dew dripping space between the heat exchanger and the outlet side surface of the housing, and
• the fixing component has:
• an attachment portion attached to the outlet side surface of the housing,
• a heat exchanger placement portion in which the heat exchanger is placed, and
• a laterally extending portion that extends laterally between the attachment portion and the heat exchanger placement portion so as to form the dew dripping space, the heat exchanger placement portion extending along a length of the heat exchanger at a 90 degree angle longitudinally from the laterally extending portion.
