本発明は高温多湿空気と他の気体との間の熱交換に適す
る熱交換器に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a heat exchanger suitable for heat exchange between hot and humid air and other gases.
熱交換器は温度効率が高いほど、従って同一形状ならば
熱通過率が高いほど性能がよくなるから金属材料によっ
て形成することが最も好ましい。The heat exchanger is most preferably formed of a metal material because the higher the temperature efficiency, and hence the higher the heat transfer rate if the shape is the same, the better the performance.
一方工業用熱交換器ではコストよりも性能が重視される
のに対して空調換気開用等家庭用熱交換器ではコストの
点も重要課題となる。On the other hand, for industrial heat exchangers, performance is more important than cost, whereas for household heat exchangers, such as those used for air conditioning and ventilation, cost is also an important issue.
斯る事情下にあって従来の空調換気扇用熱交換器はコス
ト高で重量が増し勝ちな金属製とすることを避は合成樹
脂、紙等の素材を用いて熱交換素子を形成しているため
素子自体が熱通過率の低いものになって性能面がコスト
低減の利点以上に低下してしまう欠点があった。Under these circumstances, conventional heat exchangers for air conditioning ventilation fans are made of metal, which tends to be expensive and heavy, and instead are made of materials such as synthetic resin or paper to form heat exchange elements. As a result, the element itself has a low heat transfer coefficient, resulting in a disadvantage that the performance is lower than the advantage of cost reduction.
本発明は上記の欠点を除去すべくなされたものであり、

できて熱交換効率の向上を図り得る一方、金属板の使用
量も極力削減できて軽量化及びコストの低減も図り得る
熱交換器を提供するにある。The present invention has been made to eliminate the above-mentioned drawbacks,
The purpose of this is to form the heat exchange element from synthetic resin and metal plate, and by making the high-temperature and humid air passages made of synthetic resin, it is possible to expect a heat transfer rate higher than the original value of the material, improving heat exchange efficiency. It is an object of the present invention to provide a heat exchanger that can reduce the amount of metal plates used and reduce weight and cost.

向上を図るようにしたものである。(Summary of the Invention) The heat exchanger of the present invention consists of a flat box element made of synthetic resin with a large number of primary air passages formed therein and a bent plate such as a corrugated plate formed of a metal plate, which are arranged alternately to form a cross-flow shape. It is designed to improve heat exchange efficiency by forming layers in a laminated manner to suppress increase in weight and cost as much as possible.

機外に排出するようにしている。An embodiment in which the present invention is applied to a dryer to obtain a dehumidifying function will be described below with reference to the drawings. 1st
The figure shows a well-known dehumidifying type dryer, and the outline of its configuration is as follows. That is, reference numeral 1 denotes a rotary drum rotatably disposed within an outer box 2, and is driven to rotate by a motor 3 together with a fan 4 via a belt transmission means (not shown). When the fan 4 is driven, the air blowing mechanism of this dryer is configured such that when the fan 4 is driven, the outside air (secondary air in this example) is transferred to the air intake passage 9, which has an external suction port 6, a heat exchanger 7, and a heater 8, and an internal suction port, as shown by an arrow 5a. The high-temperature and humid gas (-number air) that is sucked into the rotating drum 1 through the hole 1o and has taken moisture from the clothes is passed through the internal exhaust port 11, the filter 12, the internal duct 13, the fan 4, the exhaust duct 14, and It is configured to pass through the heat exchanger 7 as shown by an arrow 5b and then be discharged to the outside of the machine via an external exhaust port 15, whereby the gas in the rotating drum is dehumidified by the heat exchanger 7. It is then discharged from the machine.

照）を通す組合せ状態にて使用するものである。Next, the heat exchanger 7 that operates in this manner will be explained with reference to FIGS. 2 and 3. That is, 16 is a flat box element made of synthetic resin, for example, by extrusion molding, and has an overall rectangular shape with a large number of primary air passages 17 that are mutually divided and open at both ends. . 18 is a bent plate, for example, a corrugated plate, which is made by bending a metal plate, and the corrugated plate 18 and the flat box element 16 are alternately arranged so that the corrugated plate 18 is sandwiched between the elements 16. layered on. In this case, the secondary air passages are formed on both sides of the corrugated plate 18 by laminating the layers in such a manner that the wave-shaped traveling direction of the corrugated plate 18 matches the longitudinal direction of the primary air passage 17 of the flat box element 16. 19 is the number airway 17
and form a cross-flow heat exchange section. After the above-described lamination is completed, as shown by the two-dot chain line in FIG. 2, a retainer R20 having a single-shaped cross section is attached to each ridgeline portion of the laminated material to fix the laminated state. When such a heat exchanger 7 is used in the dryer shown in FIG.
A hot and humid gas (see arrow 5b) is passed through the corrugated plate 18.
It is used in a combination state in which outside air (see arrow 5a) is passed through the secondary air passages 19 formed on both sides.

場合に比しはるかに軽量で且つコストやすになる。In other words, compared to the case where both of the two elements laminated to form the heat exchanger are made of synthetic resin, one of the elements (the corrugated plate) is made of metal, so naturally the heat exchange efficiency is lower. will improve. In particular, since high-temperature and humid air is passed through the primary air passage 17 of the flat box element 16 made of synthetic resin with low thermal conductivity, a water film is formed on the surface of the numeral air passage by cooling and condensation. In addition, the corrugated plate 18 directly contacts the flat box element 16 to exert a fin effect and promote condensation within the flat box element 16. Higher heat exchange efficiency can be expected when one element is made of synthetic resin and the other element is a metal plate. Furthermore, since the smaller corrugated plate 18 is made of metal, it is much lighter and less expensive than the case where the large flat box element 16 is made of metal.

It can be implemented with various modifications.
