Description of the Related Art For example, as shown in FIG. 6, a heat exchanger 2 is arranged in an inclined posture so as to cross an air passage in a casing 1, and the heat exchanger 2 is positioned below the heat exchanger 2. A well-known air conditioner is provided with a blower 3 that blows air that passes through the device 2 from above to below, and a drain pan 4 that is arranged below the lower end of the heat exchanger 2.

場合、あるいは熱交換器２を通過する風量が大きくなる
と、熱交換器２からの水飛びが発生し、空気調和機外に
水漏れを起こすおそれがある。However, when the air conditioner having the above-described structure is in the cooling operation, the heat exchanger 2
Drain D is generated. The drain D is supposed to be made to flow down to the drain pan 4 below through the fins which have been subjected to the hydrophilic treatment. However, when the hydrophilicity of the fins is deteriorated or the amount of air passing through the heat exchanger 2 is reduced. If it becomes large, water splash from the heat exchanger 2 may occur, and water may leak outside the air conditioner.

る。On the other hand, the wind speed of the air passing through the heat exchanger 2 becomes higher as it approaches the blower 3 (that is, as the air passing through the lower portion of the heat exchanger 2) as shown by an arrow W in FIG. Then, the wind velocity distribution in the heat exchanger 2 becomes non-uniform, and the capacity of the heat exchanger 2 may not be fully utilized, and water splashes more easily in the lower part of the heat exchanger 2 and cannot be received by the drain pan 4. There is also a problem.
