率が増大する。In the evaporator (A) according to the illustrated embodiment, the refrigerant inlet pipe (
The refrigerant flowing into the left header (3) from 5) flows through the refrigerant passage made up of all the tubes (1) to the right header (4), and flows out of the vessel from the outlet pipe (6). While flowing through the tube (1), air and heat flow in from the direction shown by the arrow W and cross the evaporator (A) due to the suction force of the fan (20), as shown in Figure 1. Make an exchange. Since the heat exchange section (10) has a relatively small fin pitch on the windward side and a relatively large fin pitch on the leeward side with respect to the circulating air, generally, the heat exchanger (10) has a relatively large fin pitch on the windward side. A part of the circulating air that tends to concentrate is guided to the leeward side where air flow resistance is small. As a result, air circulates evenly throughout the heat exchange section (10), increasing the overall heat exchange efficiency.

Fourth
In the figure, the same components as in FIGS. 1 to 3 are designated by the same reference numerals, and the explanation thereof will be omitted. Further, the tube pitch and fin pitch need not be changed in two stages as in the illustrated embodiment, but may be changed in three or more stages, or the change in the tube pitch or fin pitch may be performed in three or more stages. It may be changed continuously from the upper side to the leeward side. In addition, the type of heat exchanger is not limited to the multi-flow type, as long as the heat exchange section consisting of tubes and fins is arranged at an angle with respect to the air flow direction. .

換器となしうる。Effects of the Invention As described above, the present invention has a heat exchange section in which tubes and fins are alternately arranged, and the heat exchange section is inclined with respect to the flow direction of circulating air for heat exchange. In the arranged heat exchanger, the air flow resistance of the heat exchange section is set to be relatively large on the windward side and relatively small on the leeward side. Therefore,
Since the local passage of air toward the windward side, which generally tends to occur when the heat exchange section is arranged at an angle with respect to the air flow direction, can be suppressed, and a part of the air can flow toward the leeward side, the heat exchanger can be suppressed. Sufficient heat exchange can also be performed in the leeward region of the exchange section. As a result, the heat exchange capacity of the heat exchange section can be effectively utilized, and a heat exchanger with excellent heat exchange efficiency can be obtained.
