Abstract

PURPOSE:To provide a honeycomb type cylindrical heat exchanger with a high thermal efificiency and a less loss of pressure by a method wherein adjoining sheets are layered to each other to form the adhered portions and non-adhered portions, each of said sheets is expanded in such a way as they are moved away from each other and flow passages are formed between the sheets at the non-adhered portions. CONSTITUTION:Each of adhesive agents 4 and 7 is coated on the adjoining sheets 3 and 6 in such a way as a space between the non-adhered portions 5 and 8 is gradually expanded toward the axis of the honeycomb type cylindrical heat exchanger and further as the adhesive agent 7 is overlapped at the center of the non-adhered portions 5. Then, the sheets 3 and 6 are layered and adhered to each other and the upper and lower parts of the layered adhered sheets are fixed by aluminum plates 9 and 10 or the like, each of the sheets is expanded around one end edge of the sheet and the aluminum plates 9 and 10 are fixed to each other, resulting in that a honeycomb type cylindrical heat exchanger A forming a flow passage between the sheets at the non-adhesive portions is formed. As a result, different flow passages can be formed and a heat exchanger unit which is highly efficient, sutable for an automatic operation and has a less reduction in pressure.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a honeycomb type cylindrical heat exchanger used for heat exchange ventilation loading to reduce heat loss during ventilation. One type of heat exchanger used in heat recovery equipment is one that uses a rotating rotor as a heat exchanger. In the case of a rotary total heat exchanger that reduces heat loss during ventilation, etc., a corrugate-like material made by superposing a flat sheet 1 and a corrugated sheet 2 is wound into a spiral shape to form a cylinder, as shown in Fig. 12. There are tjq structures that use a heat exchanger as a heat exchanger, and structures that use scrap metal wire or hygroscopic natural fibers formed into a net-like The flow paths inside the vessel can only be simple.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a honeycomb-type cylindrical heat exchanger that is more efficient, simpler, more suitable for automation, and has less pressure loss than conventional heat exchangers.

Structure of the Invention In order to achieve the above object, the present invention includes stacking adjacent sheets so as to form a bonded part and a non-bonded part, spreading the sheets apart from each other, and forming a gap between the sheets in the non-bonded part. This is a honeycomb type cylindrical heat exchanger that forms a flow path in the sorting surface. Different flow paths can be formed by changing the adhesive application pattern on the sorting surface, and the honeycomb type cylindrical heat exchanger is highly efficient. It can be used as a heat exchanger.

In both FIG. 1 and FIG. 8, the adhesive portion 4.7 on the flat sheet,
22, 26, 30.34 are widened from the outer circumferential side to the inner circumferential side in the direction of the shafts 12, 41. This is to make the opening areas of the air flow passages on the inner circumferential side and the outer circumferential side the same, thereby making the air flow distribution uniform and improving the heat exchange efficiency. Furthermore, the distance between the bonded portion 15.18 and the non-bonded portion 16.19 in FIG. 4 is widened from the outer circumferential side to the inner circumferential side in the direction of the axis 12, and this is also for the same reason as described above.

A single honeycomb-type cylindrical heat exchanger may be constructed with 2 as the center.

In this embodiment, kraft paper is used as the material for the heat exchanger, but it may also be made of a plastic sheet or a metal foil such as aluminum foil.

Effects of the Invention As is clear from the description of the embodiments above, the sheet lamination method can be adopted and automation is therefore easy, so it is not only possible to reduce the cost of the heat exchanger, but also to reduce the cost of the heat exchanger. By changing the coating pattern, honeycomb-type cylindrical heat exchangers with various flow paths can be made. In addition, the spacing between the non-adhesive parts of the application pattern becomes wider from the outer circumferential side to the inner circumferential side in the axial direction during deployment.
The opening areas of the flow passages on the outer periphery (Ill) and the inner periphery side are equal, and the airflow distribution becomes uniform, so that the heat exchange efficiency is improved.

Furthermore, by increasing the area of the bonded portion, the peel strength between the sheets also increases.
