Heat exchanger headers with buffer and damping materials

A heat exchanger comprising:

• a heat exchanger body which includes
• a tubular upper header and a tubular lower header which are provided with a gap therebetween in an upward-downward direction,
• a plurality of tubes which are arranged between the upper header and the lower header and are connected to the upper header and the lower header, and through which a refrigerant flows,
• fins which are provided between the tubes provided at positions adjacent to each other,
• a pair of lower buffer materials, each lower buffer material covering one end of a lower outer peripheral surface of the lower header, and
• an adhesive lower damping material which is provided on the lower outer peripheral surface of the lower header and is formed such that each of both end portions of the lower damping material is extended between the lower header and the lower buffer material;
• and
• a casing which includes a first abutment portion against which one of the lower buffer materials provided in both end portions of the lower header abuts, a second abutment portion against which the other thereof abuts, and a condensate water discharger which is provided below the first and second abutment portions,
• wherein the condensate water discharger, the first and second abutment portions, and the lower damping material define a condensate water discharge space, and
• the casing includes a discharge port through which condensate water is discharged to an outside from the condensate water discharge space.
