れていた。Conventionally, an aluminum fin copper tube type heat exchanger, an all aluminum type finned heat exchanger, or the like has been used as an indoor or outdoor heat exchanger for this type of heating/cooling device. The configuration will be explained below with reference to FIG. 2. As shown in the figure, a refrigerant passage tube 23 is connected between the first header 21 and the second header 22 provided in the vertical direction of the all-aluminum heat exchanger 20, and each of the refrigerant passage tubes 23
In addition, the first header 21 or the second header 22 has an inlet part 25 and an outlet part 2 made of aluminum for refrigerant, which is a working fluid, at the upper and lower ends thereof.
A copper inlet lead vibe 27 is welded to the inlet section 25 and a copper outlet lead pipe 28 is welded to the outlet section 26 with argon. Partition plates 29 are installed in the first header 21 and the second header 22 so that the refrigerant flows through the plurality of flow path tubes 23 and the passage area gradually decreases as it goes upward toward the outlet section 26. .30.31 are provided to constitute the heat exchanger 20. Then, the outside of the fin 24 is covered with a reinforcing plate 32.
33, and the connection point between the inlet part 25 and the copper inlet lead vibrator, and the connection point between the upper outlet part 26 and the outlet lead pipe are connected to the first part due to the processing jig, and the protruding dimension from the da is approximately Consisting of the same dimensions. Therefore, condensed water is generated around the outlet section 26 or the outlet lead pipe 28, and the condensed water containing copper ions drips to the inlet section 2 at the lower end.
5, there is a problem in that corrosion progresses around the inlet portion 25. Therefore, the area around the joint between the inlet section 25 and the outlet section 26 is treated with a highly weather-resistant coating, and a resin tube is installed around the area to suppress moisture penetration and prevent corrosion. A method was taken.

成するものである。Means for Solving the Problems In order to achieve the above-mentioned object, the present invention has the following objectives: the lower end of the heat exchanger is arranged so that the inlet and outlet parts of the heat exchanger and the joint points of the lead pipes connected thereto are not on the same drop line. The joint point of the part is arranged closer to the first end so that water droplets dripping from the upper end part, especially around the copper outlet lead vibrator, do not hit the part.

It does not drip around the joint, and can be expected to have a corrosion inhibiting effect, and even if it adheres to the lower end, it will flow outward rather than staying in the aluminum inlet.
実施例
以下、本発明の一実施例を第１図を参照しながら説明す

The refrigerant flow path tubes 3 are joined by fins 4. An outlet pipe 5 made of aluminum is provided in the upper part of the first ladder 1.
is provided with a longer protruding length from the first header 1, and an aluminum inlet pipe 6 is provided in the lower part of the first header 1 to be shorter than the outlet pipe 5. The outlet side lead pipe 7 made of steel pipe and having a substantially circular arc shape is connected with the outlet facing downward, and the joint part (A) is welded.

る。Then, an arc-shaped inlet lead pipe 8 made of a steel pipe is joined to the inlet pipe 6 with the inlet facing downward, and the joined part (B) is welded. Further, the first header 1 is arranged such that the refrigerant flowing from the inlet pipe 6 flows uniformly through the plurality of refrigerant flow path tubes 3 and the passage area becomes smaller sequentially toward the outlet pipe 5.
A partition plate 9, 10, 11 is provided in the second ladder 2. A reinforcing plate 12 for reinforcing the outside of the fins 4 is provided to constitute a heat exchanger 13. Also, artificial tube 6
The inlet side lead pipe 8 and the joint part (B) are covered with a thermosetting resin tube 14. Note that the inlet pipe 6
The surfaces of the inlet-side lead pipe 8, the outlet pipe 5, and the outlet-side lead pipe 7 are coated to prevent corrosion.

に落下することがなくなる。In the above configuration, the refrigerant flowing from the inlet pipe 6 undergoes heat exchange within the heat exchanger 13, and the low-temperature refrigerant is sent to the outlet pipe 5, thereby cooling the outlet pipe 5 and the outlet side reed vibe 7, and forming the joint part (A). Condensation water is generated in the surrounding area, and the condensation water containing copper ions drips downward. At this time, the joint part (B) between the inlet pipe 6 and the inlet lead vibe 8 provided in the lower part is located inside the first header l by the L dimension from the joint part (A) on the outlet side, and the condensed water is removed. Since the condensed water dripping from the joint part (A) of the outlet pipe 5 does not fall onto the inlet pipe 6, the condensed water drops from the joint part (A) of the outlet pipe 5.

が少なくなる。As described above, according to the heating/cooling heat exchanger of the embodiment of the present invention, the joint part (B) on the inlet pipe 6 side is the joint part (B) of the five outlet pipes (
Since it is located inside A), it is possible to reduce the amount of condensed water containing copper ions that falls from the joint part (A) of the five outlet pipes, and to prevent corrosion caused by the condensed water. Also,
Since both the inlet side lead vibe 8 and the outlet side lead vibe 7 are formed in a downward arc shape, the condensed water adhering to the inlet side lead vibe 8 and the outlet side lead vibe 7 is transferred to the inlet pipe 6 and the outlet pipe 5 side. There is less flow to
Corrosion of the aluminum inlet pipe 6 and outlet pipe 5 can be prevented. Further, since the tube surfaces of the inlet pipe 6 and the inlet lead vibe 8, as well as the outlet pipe 5 and the outlet lead vibe 7 are coated, the proportion of copper ions dissolved in the condensed water is reduced.

きる。Effects of the Invention As is clear from the above embodiments, the joint between the inlet pipe and the lead vibe provided in the lower part is shifted to the inner side of the joint part between the outlet pipe and the lead pipe provided in the upper part. Therefore, it is possible to reduce the contamination of the inlet pipe in the lower part by condensed water falling from the outlet pipe side in the upper part, and to provide a heat exchanger for heating and cooling in which the progress of corrosion is alleviated.
