〈産業上の利用分野〉
本発明は除湿機能をもつプレートフィン型熱交換器器に
関するものである。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a plate-fin type heat exchanger device having a dehumidifying function.
〈従来の技術〉

ものであり、除湿の効果が不十分である。<Prior art> A conventional heat exchanger for an air conditioner with a dehumidifying function that performs cooling and reheating has a heat exchanger vibrator a that allows refrigerant to flow in, and a heat exchanger vibrator that allows hot water to flow in, as shown in Figure 2. A cooling and dehumidifying refrigerant heat exchange section d is installed perpendicularly to a large number of fins C with the exchange pipe b in the front and rear positions, and serves as a first heat exchange section on the suction air side, and a second heat exchange section on the discharge air side. The configuration is such that the hot water heat exchange section e for reheating is used as an exchange section. In this case, the hot water flows against the direction of gravity, that is, the hot water flows in from the lower end of the hot water heat exchange section C and flows out from the upper end, and the dehumidification effect is insufficient.
〈発明が解決しようとする課題〉
即ち、このように除湿効果が不十分な理由は、吸込み空
気の上流側の冷却管（熱交換バイブａ）で凝縮した水分
がフィンＣを伝わって流下する。<Problem to be Solved by the Invention> That is, the reason why the dehumidifying effect is insufficient is that the moisture condensed in the cooling pipe (heat exchange vibe a) on the upstream side of the intake air flows down through the fins C.
一方、再熱用温水熱交換部ｅの温水コイル（熱交換バイ
ブｂ）の熱はフィンＣにより冷媒側にも一部伝導するた
め、温水人口側（下部）付近のフィンＣ側は上部ｆ付近
と比較して高温となる。従って、流下した水分は再蒸発
しやすいものとなる（第３図参照）。On the other hand, the heat of the hot water coil (heat exchange vibe b) of the hot water heat exchange section e for reheating is partially conducted to the refrigerant side by the fin C, so the fin C side near the hot water population side (lower part) is near the top f The temperature is higher than that of Therefore, the water that flows down is likely to re-evaporate (see Figure 3).
本発明は上記実情に鑑み、温水を上から下への流すこと
で、上記課題を解決するプレートフィン型熱交換器を提
供することを目的としたものである。In view of the above circumstances, the present invention aims to provide a plate-fin type heat exchanger that solves the above problems by flowing hot water from top to bottom.

本発明は、プレートフィン型熱交換器において、冷媒用
熱交換パイプと温水用熱交換パイプを同一フィンを使用

端から流出するようにしたものである。Means for Solving the Problems> The present invention provides dedicated dehumidification in which the same fins are used for the refrigerant heat exchange pipe and the hot water heat exchange pipe in a plate-fin type heat exchanger, and cooling heat is provided upstream of the intake air. An exchange pipe is provided, and a heat exchange pipe for hot water is provided on the discharge air side, and hot water flows in from the upper end in the direction of gravity and flows out from the lower end.

上記のような構成のため、再熱用温水熱交換部における
温水人口が上端にあり、流出口が下端にしてなるため、
下端部のフィンが高温とならず、フィンを伝わって滴下
する露が再蒸発しにくい。即ち、温水熱交換部の下部に
温水出口を配設しているので、この温水熱交換部の温度
は上部の温度に比較して低く露の再蒸発をみない。Due to the above configuration, the hot water population in the hot water heat exchange section for reheating is at the upper end, and the outlet is at the lower end.
The fins at the lower end do not reach high temperatures, making it difficult for dew that drips down the fins to evaporate again. That is, since the hot water outlet is disposed at the lower part of the hot water heat exchange section, the temperature of the hot water heat exchange section is lower than the temperature at the upper part, and re-evaporation of dew does not occur.
〈実施例〉
以下、本発明を実施例の図面に基づいて説明すれば、次

熱用温水熱交換部６の境目に刻設したスリットである。Reference numeral 1 denotes a plate-fin type heat exchanger provided in a hot water type air conditioner indoor unit (not shown). It is inserted through a large number of orthogonal fins 4, and the part arranged in two rows on the side of the suction air A is used as the cooling and dehumidifying refrigerant heat exchange part 5, and the part arranged in one row on the side of the blown air B is reheated. The refrigerant heat exchange pipe 2 has an upper end as a refrigerant outlet 2a, an upper end of the hot water heat exchange pipe 3 as a hot water outlet 3a, and a lower end as a hot water outlet 3b. 2b is an outlet of the refrigerant heat exchange pipe 2. Reference numeral 7 denotes a slit cut at the boundary between the refrigerant heat exchange section 5 for cooling and dehumidification and the hot water heat exchange section 6 for reheating.

である。Next, to explain this effect, first, in the refrigeration cycle that is in the cooling operation, as is well known, the refrigerant flow is directed from the compressor to the refrigerant heat exchange section 5 for cooling and dehumidification via the condenser and capillary tube (not shown). ), the indoor air is cooled by the heat of evaporation of the refrigerant in the cooling and dehumidifying refrigerant heat exchange section 5.

The refrigerant flows into the dehumidifying refrigerant heat exchange section 5, and at the same time, hot water flows into the reheat hot water heat exchange section 6, where it is heated and maintained at a predetermined temperature for dehumidification.

発しにくく、この分だけ除湿能力を高めるものとなる。In this case, the hot water population 3a of the hot water heat exchange pipe 3 is at the upper end (side), the hot water outlet 3b is at the lower end, and the lower part of the fin 4 does not reach a high temperature, which prevents the adhesion of moisture in the condensed air. The dripping dew C transmitted through the fins 4 is difficult to evaporate again, and the dehumidifying ability is increased by this amount.

By setting the hot water population of the heat exchange pipe of the heat exchanger section at the upper end and the outlet at the lower end, the lower part of the fin does not become high temperature, making it difficult for the moisture in the air that has condensed to evaporate again. This increases the dehumidification effect.
