Abstract

PURPOSE:To improve the assembly working property of the heat exchanger by a structure wherein a pair of flange-shape unit wall parts are formed at both ends of a heat exchange element and said unit wall parts are laminatedly juxtaposed leaving no space in the heat exchanger composed of tubular heat exchange elements. CONSTITUTION:The heat exchange element 1 consists of a synthetic resin moisture permeable pipe having a pair of rectangular flange-shape unit wall parts 2 equipped with a frame part 2a at its both ends made into an integral body. The heat exchanger is formed by laminatedly juxtaposing said frame parts 2a of the unit wall parts 2 so as to contact with one another leaving no space therebetween. In the structure as mentioned above, primary air is flowed within the heat exchange elements 1 as indicated with the arrows A, while secondary air is flowed between the heat exchange elements 1 in the direction as indicated with the arrows B. Consequently, the primary and the secondary airs A and B are heat- exchanged with each other. Because the heat exchanger is assembled in such a simple work as to laminatedly juxtapose the unit wall parts 2 and to hold by means of a holding frame 4, the improvement of the assembly working property of the heat exchanger is resulted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat exchanger with a plurality of heat exchange elements consisting of pipes.

Conventionally, this kind of heat exchanger has two end plates each having a large number of fitting holes, and one fitting hole of the two end plates is inserted into the fitting hole of the two end plates.
The plate holds a plurality of heat exchange elements arranged at a certain interval and maintains the arrangement state -ζ, and the wrinkles allow heat exchange between the air passing through the arrangement space and the air passing through the heat exchange element □. Shimome is served. However, with this, the work of inserting the end of the heat exchange element into the fitting hole of the end plate is troublesome, and moreover, this work has to be done many times because the heat exchange element has a force of 5 increments of 1 m. First, one end of the heat exchange element is inserted into the fitting hole of one end plate, and then the heat exchange is performed.
When inserting the other end of the element into the fitting hole of the other end plate, 1
%Align one end of the heat exchange element with the fitting hole of the other end plate, taking care not to separate it from the other end plate, and then insert it. However, the task was quite time consuming and had the drawback of being difficult to prepare in general.

The present invention has been made to eliminate the above-mentioned drawbacks, and its purpose is to provide a heat exchanger that can be easily assembled.

1 and II/IJ2 for the first embodiment of the present invention.
This will be explained with reference to the figures. A single-wire plurality of heat exchange elements is constructed from a pipe made of a moisture-permeable material made of a synthetic resin with a large amount of fibers, and a rectangular flange-shaped unit wall part with a frame part 2 a L 2 a at both ends. 2, 2 are integrally formed. Therefore, the unit wall parts 2, 2 of the ξΦ heat exchange element 1 have frame parts 2m, 2m that correspond to the single position part 2 of the other heat exchange element 1.
, 2 and the frame portions 21 . In addition, the unit walls 2, 2 of the heat exchange element 1 are laminated and juxtaposed, and each end shielding wall 3.3# (4) is formed as a whole. 4 is a holding frame 1, 1 which also serves as a case. The front and rear surfaces of ≠ are open, and vent holes 5.5 are formed on the left and right sides.The heat exchange element 1 is designed to maintain the arrangement state of the arrayed elements 1. It is held by the frame 4. In this stored state, in front of the holding frame 4.

The rear opening part is covered with the above-mentioned shield Il! 5 and 3), therefore, a ventilation passage 6 is formed in the holding frame 4 that opens to the left and right sides.

In the heat exchanger configured as described above, - Large air is passed through the heat exchange element 1 from the front end opening and passes between the rear ends as shown by the arrow mark, and - Two particles having a temperature different from that of the large air are Next air is passed through the holding frame 4 and the arrangement space of the heat exchange element 1 through the right ventilation hole 5 and through the left ventilation hole as shown by arrow B, thereby forming primary air and secondary air. Since the heat exchange element 1 has moisture permeability during this heat exchange, so-called hot air exchange between the large air and the secondary air is also performed. .

1j. According to such a wood example, the brim-like single-layer wall portions 2, 2 are formed at both ends of the heat exchange element 1, and the unit wall portions 2 are stacked and arranged side by side. The heat exchange elements 1 can be assembled in a predetermined array 1111ζ by the simple operation of stacking and juxtaposition, thereby improving assembly efficiency.Also, by stacking and juxtaposing the unit walls 2 without gaps] Since the shielding wall 5 that closes both openings is formed, it is possible to construct the opening of the ventilation passage 6 by the shielding wall 3. Therefore, a wall member for forming the ventilation passage 6 is also required separately. do not.

Furthermore, according to this embodiment, in addition to the above-mentioned basic structure, the following effects can be obtained. That is, the heat exchanger 1 is made of j181 material
As a result, the heat exchange element 1, which is a single member, can perform not only heat exchange but also moisture exchange, and therefore can be multi-functionalized without complicating the structure.

In addition, since the unit wall portion 2 is integrally formed with the heat exchange element 1, the time required for attaching the unit wall portion 2 to the heat exchange element 1 is reduced (unlike when the single position portion 2 is a separate body). However, it is more effective in improving the ease of assembly.

In addition, even if the unit wall part 2 is separate from the heat exchange element 1 and the work of connecting them is added, the entire subsequent assembly work is much easier than the conventional model ζ mentioned above. Therefore, the above-mentioned basic effect of improving assembly efficiency is obtained.

Next, a second embodiment of the present invention will be described with reference to FIGS. 5 and 5, with respect to points different from the first embodiment. The holding frame 7 has a ventilation hole 6 at the front edge i of the left side wall of i and at the rear part of the right side wall.
．． 8 is formed, and the heat exchange element 9 is formed with a bulging part 10 in the shape of an octagonal cylinder, for example, which has a large flow path area in the middle part thereof. Further, the bulging portions 10 are in close contact with each other in the vertical and horizontal directions, and a small air passage 11 along the heat exchange element 9 is carved between the bulging portions 10.

In this second implementation, the large air is connected to the heat exchange element as shown by arrow C! Also, the secondary air is passed through the holding frame 7 as shown by the arrow.

When the primary air enters the bulging portion 10, its flow velocity slows down and the flow becomes turbulent. The secondary air flowing into the bulge 7 flows through the small air passage 11 facing the primary air within the bulge 10'. In the case of "C", the flow velocity of the large air becomes slow in the bulging part 10 and the flow becomes turbulent, so that the degree of contact with the wall surface of the bulging part 10 increases, and as a result, heat exchange with the secondary air increases. Exchange efficiency is improved. In addition, when the secondary air exits the small air passage 11, its flow velocity slows down and the flow becomes turbulent, so the degree of contact with the heat exchange element 9 increases, and as a result - the heat exchange efficiency with the large air decreases. Overall, according to the second embodiment, in addition to the effects achieved by the above-mentioned first embodiment, the heat exchange efficiency can be further improved.

Next, FIG. 6 shows a fifth embodiment of the present invention, which differs from the fifth embodiment in that a plurality of bulges 13 are formed on each heat exchange element 12 in the dormitory embodiment. . According to this embodiment, the number of locations where the flow velocity of large air and secondary air is relaxed and where turbulence occurs is increased, so that the heat exchange efficiency is further improved.

FIG. 7 shows a fourth embodiment of the present invention).
This is different from the second embodiment described in □ in that the shape of the ``°°'''' is square, and the corners of the bulges s15 are in contact with each other.

However, the same effects as in the fifth embodiment can be achieved in the second vs. dormitory embodiment.

Figures 8 to 10 respectively show the fifth and seventh dormitory embodiments of the present invention, and these 5j! This example differs from the actual example in the following points. That is, the 81st! ! ! ! In the fifth embodiment shown in FIG. 1, the unit wall 16 is formed within the thickness of the center, and in the sixth embodiment shown in FIG.
