斜波形状に配設することも考えられる。[Prior Art] Generally, there is a tendency for air conditioners to be made smaller and thinner, whether they are wall-mounted or floor-mounted. However, even when the air conditioner is made thinner, it is necessary to obtain the desired heat exchange performance, and for this purpose, it is necessary to effectively utilize the small space inside the air conditioner body to maximize the heat exchange rate. It is necessary to ensure that Therefore, in consideration of the discharge of condensed water, the heat exchanger is generally arranged in an inclined manner within the air flow path. In this case, the conventional heat exchanger, as shown in FIG. A structure consisting of heat exchange fins b was used. However, although a conventional heat exchanger of this kind can achieve a high heat exchange efficiency, it requires a plurality of heat exchange tubes a, so there is a limit to how thin the heat exchanger can be made. As a means to solve this problem, it is also possible to form a heat exchange tube by bending a flat tube in a serpentine shape in the vertical direction, and arranging heat exchange fins in the shape of an inclined wave between the meandering parts of the heat exchange tube. It will be done.

題もある。[Problems to be solved by the invention] However, even in this type of heat exchanger,
When used for air conditioning, condensed water adheres to the heat exchange fins b and increases air resistance, which may reduce the amount of air circulation and impede heat exchange performance. There is also the problem that the condensed water cannot ride the airflow passing through it, causing water droplets to accidentally fall into the room.

ある。[Means for solving the problem] In order to achieve the above object, the heat exchanger for an air conditioner of this invention has an air inlet and an air outlet provided at the top and bottom of the air conditioner body. Assuming that the heat exchanger is arranged in an inclined manner in the communicating air flow path, the heat exchange tube is made by bending a flat tube in a meandering manner in the vertical direction, and the inclined wave is created between the meandering portion of the heat exchange tube. Consisting of heat exchange fins arranged in the shape,
The inclined lower surface portion of the heat exchange tube and the end portion of the heat exchange fins form an edge portion for discharging condensed water.

下を防止することができる。 By forming a heat exchange tube bent in a meandering manner in the vertical direction in the air flow path as a flat tube, and arranging heat exchange fins in an inclined wave shape between the meandering portions of the heat exchange tube, Air flowing within the air flow path undergoes heat exchange evenly. In addition, the condensed water generated during cooling is smoothly guided downward without adhering to the heat exchanger through the condensed water discharge edge, so water droplets adhere to the heat exchange fins and cause air resistance. It is possible to prevent a decrease in the amount of air circulation without increasing the amount of air.

After being sucked into the flow path 4 and cleaned by the air cleaner 6, it passes through the heat exchanger 10. At this time, the air is evenly heat exchanged by the flat heat exchange tube 14 and the heat exchange fins 16, and is blown out from the air outlet 3 into the room.
Furthermore, when the heat exchanger 10 is used for cooling, condensed water generated during heat exchange flows downward through the heat exchange tubes 14 and the inclined heat exchange fins 16, and flows to the inclined lower surface of the heat exchange tubes 14. After being received by the provided edge portion 18 for discharging condensed water, it is guided to the drain receiving portion 5 by this edge portion 18 .

る。1. Since the heat exchange tube is formed by bending the flat tube in a meandering manner, and the inclined wave-shaped heat exchange fins are disposed between the meandering portions, the heat exchange area can be increased, and A high heat exchange rate can be obtained, the heat exchanger can be made thinner and more compact than a heat exchanger of the same efficiency, and the air conditioner can be made thinner and more compact.

ることができる。2 The heat exchange fins are formed in an inclined wave shape, and the condensed water discharge edge is formed by the sloped lower surface of the heat exchange tube and the end of the heat exchange fins, so that condensed water can be drained well. This prevents an increase in air resistance and a decrease in air circulation due to water droplets adhering to the heat exchange fins, and also prevents inadvertent humidification and water droplets from falling into the room.
