Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger used for a heat exchange type ventilation fan or the like.

[0002]

2. Description of the Related Art In recent years, heat exchange type ventilation fans and the like, which are effective in saving energy, have become widespread, and the heat exchanger used therein has a structure as shown in FIGS. Less than,
The configuration will be described with reference to FIGS. 3 and 4.

As shown in the figure, 101 is a thin plate-shaped heat transfer plate made of paper or plastic, and a corrugated spacing plate 10.
3 is a heat exchange plate which is bonded to the heat exchange plate 10.
Mounting plate A10 in which a plurality of heat-exchange elements 104 are formed by alternately stacking 1 by 90 degrees and locking the handle 105.
6, the mounting plate B 107, and the plurality of columns 108 formed in the four corners surround the heat exchange element 104, and the plurality of screws 109 fix the heat exchange element 104 to form the heat exchanger 110. In the above configuration, the mounting plate A106 and the mounting plate B
The strength of the heat exchanger is maintained by fixing the 107 and the pillar 108 with a plurality of screws 109.

[0004]

In such a conventional heat exchanger 110, the heat transfer plate 10 is generally used for total heat exchange.
2 and the spacing plate 103 are made of paper, in this case, the heat exchange element 104 is very fragile, and the spacing plate 10 is easily cleaned during cleaning.
There is a risk that the eyes of # 3 may be crushed or damaged when dropped, and if used for a long time, the heat transfer plate 102 and the spacing plate 1
03 had a problem in durability that it contracted by repeating moisture absorption and drying.

Further, there is a problem that the number of parts for forming the heat exchanger 110 is large and the manufacturing cost is high.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a heat exchanger which has little change over time, has durability, and is inexpensive to manufacture.

[0007]

In order to achieve the above object, the present invention provides a handle for holding a heat exchanger, a notch for locking the handle and a hole for passing a resin pipe. The mounting plate provided with and a plurality of fixing holes are integrally molded on both surfaces of the heat transfer plate so that the plurality of ribs are orthogonal to each other on the both sides of the heat transfer plate, and the partition plates are bonded to form a heat exchange plate. A heat exchange element in which a plurality of layers are laminated and a resin pipe are provided, and both ends of the resin pipe are welded to fix the mounting plate and the heat exchange element.

[0008]

According to the present invention, by applying heat to both ends of the resin pipe, the both ends of the resin pipe are melted and deformed to form ring seats, and the mounting plate and the heat exchange element are fixed to each other. It can be a heat exchanger.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, 1 is formed on the front surface of a heat transfer plate 3 made of paper or resin, 2 is formed on the back surface of the heat transfer plate 3, and a plurality of them are provided so as to be orthogonal to the front surface and the back surface, respectively. The heat transfer plate 3 is sandwiched between the ribs that are provided, and the heat transfer plate 3 is integrally molded with resin. Reference numeral 4 denotes a plurality of fixing holes which are integrally formed with the rib 1 and have a slight bulge and are formed so as to penetrate therethrough. A partition plate 5 made of the same material as the heat transfer plate 3 is attached to the lower rib 2 on the lower side. The heat exchange plate 6 is formed by pasting them together to form one unit. The heat exchange element 7 is formed by stacking a plurality of the heat exchange plates 6.
8 is a mounting plate A, a notch 10 for locking the handle 9,
A plurality of holes 12 for passing the resin pipe 11 are provided. A mounting plate B 13 has a plurality of holes 14 through which the resin pipe 11 passes. The resin pipe 11 is cut longer than the total length of the heat exchange element 7, the mounting plate A8, and the mounting plate B13. Also, resin pipe 1
May be hollow or non-hollow rod-shaped.

In the above structure, the mounting plate A8 and the mounting plate B
13 and the heat exchange plates 6 as one unit are laminated to form a heat exchange element 7, and the heat exchange element 7 is sandwiched from above and below, and the resin pipe 11 is attached to the mounting plate A8 and the heat exchange element 7 , After being inserted through the holes 12, 4 and 14 of the mounting plate B13, heat is applied to both ends of the resin pipe 11 to deform the resin pipe 11 and form the ring-shaped seat 15, so that the mounting plate A8 and The mounting plate B13 is fixed to the heat exchange element 7 to form the heat exchanger 16.

As described above, the heat exchanger 16 includes the resin pipe 11
The whole can be formed and fixed simply by welding.

Further, since the ribs 1 and 2 are made of resin, the heat exchange element 7 becomes very strong, no blunting occurs during cleaning, and it is not easily deformed even when dropped, and can withstand long-term use. It will be possible.

[0014]

As is apparent from the above embodiments, according to the present invention, a plurality of ribs made of resin provided on the front surface and the back surface of the heat transfer plate are integrally formed by sandwiching the heat transfer plate. To form a heat exchange element, form a heat exchange element, and penetrate the heat exchange element and the upper and lower mounting plates with a resin pipe to heat-exchange the resin pipe. By making it a heat exchanger, the heat exchanger can be made strong, its secular change is small, and its durability can be improved.
Since the number of parts for forming the heat exchanger is small, it is possible to provide the heat exchanger which can reduce the manufacturing cost.
