図に示すような空調用熱交換器コアを完成する。 FIG. 1 is a longitudinal sectional view showing the main parts of the heat exchanger core, and FIG. 2 is a plan view thereof. As is clear from FIG. 1, a large number of holes 1 are formed in the plate fins 3 constituting the heat exchanger core, and the edges of the holes are formed into concentric collar-shaped parts 2 in multiple stages by burring. ing. Note that the collar portion 2 does not necessarily need to be formed in multiple stages. Next, concave portions 4 for condensed water reservoirs are formed in a portion of the base of this collar-shaped portion 2, respectively, facing in the same direction as shown in FIGS. 1 and 2. And in this example,
The recess 4 faces downstream of the air flow 7 and is formed slightly downward (angle α) along the direction of gravity. A large number of plate fins 3 thus formed are laminated to form a structure as shown in FIG. 4. Note that the inner and outer surfaces of each plate fin 3 are coated with a brazing material in advance. Therefore, the core 8 made of these laminates is inserted into the furnace and integrally fixed by brazing.
The continuous collar portion 2 constitutes a tube. Then, the U-shaped tube 5 is connected to the collar-shaped part 2 of the plate fin 3 located at the end, and the third
Complete the air conditioning heat exchanger core as shown in the figure.

しスリツト６を介してコア８の下端から流下し、
凝縮水が円滑に排除される。 Thus, as shown in FIGS. 2 and 3, each plate fin 3 is positioned parallel to the direction of gravity, and
Air flow 7 is passed between each plate fin 3. Then, a refrigerant is made to flow within the collar-shaped portion 2.
Then, the surface of the plate fin 3 and the collar portion 2
Condensation forms on the outside surface. This condensed water flows through the air stream 7
It goes around the collar-shaped part 2 and is smoothly captured in the recess 4. The condensed water sequentially fed into the recess 4 gradually grows and finally falls downward and flows down from the lower end of the core 8 through the slit 6.
Condensed water is smoothly removed.

ことができる。 This heat exchanger core for air conditioning has a recess 4 for condensed water at a part of the base of the collar 2, so
Condensed water adhering to the surface of the plate fins 3 flows into the recesses 4.
is captured smoothly. Therefore, it is possible to prevent condensed water from staying over a wide range on the surface of the plate fins 3, and to prevent the heat dissipation effect from decreasing due to the presence of the condensed water. Then, the condensed water can grow within the recess 4 and the grown condensed water can quickly flow downstream.
