Abstract

PURPOSE:To obtain a heat exchanger easy to manufacture by providing tape-like materials at the overlapped portions between end portions of the heat exchange elements and the overlapped portions between the heat exchange elements and spacers to increase the bonding effect at the time of applying pressure or heating, in a pi-flow type or counterflow type heat exchanger. CONSTITUTION:Each of square or rectangular heat exchange elements 13 has a plurality of parallel flowpaths 13a. Each of spacers 14 has a function to guide an air stream and a function to hold interval. Tape like materials 15 are bonded on both ends of the heat exchange element 13 in the direction of the parallel flowpath and on the spaces 14. The tape-like material 15 increases the bonding effect at the time of applying pressure or heating. Upon constituting the heat exchanger, when one-ends of the heat exchange elements 13 which are overlapped alternately, spacers 14 and other ends of the heat exchange elements are overlapped on each other and the contact portions are applied with pressure or heated, respective contact portions are immediately bonded, and the manufacture of the heat exchanger is extremely facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to heat exchangers such as π70-type and opposed C-type heat exchangers.

[Conventional technology]

Conventionally, as a counter-flow type heat exchanger, Utility Model Publication No. 52-5653
This is what was shown in Publication No. 1. This is shown in Figure 2.
Shown below. In the figure, l is a cardboard-shaped heat exchange element, and this heat exchanger! IiLfg terminals near one end 5 are stacked alternately, and the other end 2' is supplied with the closing plate 3 shown in Fig. 2 (J3).
The adjacent heat exchange elements 1 in the stacking direction
Seal the space. M indicates the flow of the primary airflow, and N indicates the flow of the secondary airflow. In this heat exchanger, after each airflow passes through the heat exchange elements 1, it passes through the central part 6 formed between the heat exchange elements 1, hits the closed substrate 3, and changes direction in the right angle direction.

In addition, Fig. 3 and Fig. 4 were filed by the present applicant in the trf application filed in 1983-
94101, a π70-type heat exchanger with a trapezoidal cross section is proposed, and 7 shows a plurality of parallel flows INr7 a 1f! for controlling the flow. : Formed plate-like fins,
A plate 81gr is formed on the upper and lower sides of the fin 7 to partition two air flows into a heat exchanger. Next, in order to give a distribution of static pressure loss in the fin 7, one end is connected to the parallel flow #67a.
The thermal conductor 9 is formed by cutting perpendicularly to the other end and diagonally cutting the other end. Finally, at the other end of the diagonally cut spacer 1, which serves both the airflow guide function and the spacing maintenance function.
0 to form a unit member 11. Then, the unit members 11 are stacked alternately so that the part with the fins 7 and the completely white part 12 without the fins 7 alternate in the stacking direction,
A π70-shaped heat exchanger having a trapezoidal cross section as shown in FIG. 4 is formed. a, &' indicate the inlet and outlet of the primary air flow M, and b, b' indicate the inlet and outlet of the two-air flow N. Of course, any unnecessary openings should be sealed with a sealing agent. Heat exchange is performed between the primary air flow M and the secondary air flow N via the plate 8. Since the airflows M and N have long opposing flow paths, good heat exchange efficiency can be obtained. In addition, the heat exchange element 9
There are two types: one with a parallelogram cross section in which one side is stacked in the opposite direction, and the other with a rectangular cross section in which square or rectangular heat exchange elements are stacked.

[Intermediate point that the invention attempts to solve]

However, in the case shown in FIG. 2 described above, the overlapped ends 5 of the heat exchange element 1 are glued together using an adhesive, and the other end 2 of the heat exchange element 1 and the closed substrate 3 are bonded together. It was necessary to attach the layers with adhesive, making it difficult to manufacture. In addition, what is shown in FIGS. 3 and 4 is a heat exchange cord 9 and a spacer 10.
During this process, the ends of the heat exchange element 9 had to be bonded together with adhesive, which made the manufacturing process troublesome.

The present invention has been made in order to solve the above-mentioned problems of the conventional technology, and it is an object of the present invention to provide a heat exchanger that is easy to manufacture.

[Means for solving inter-group points]

In the present invention, a tape-like material that exhibits an adhesive effect when pressurized or heated is provided at the overlapped portion between the ends of the heat exchange element and the overlapped portion between the heat exchange element and the spacer.

[Effect]

The overlapping portions are bonded by applying pressure or heating.

〔Example〕

Hereinafter, embodiments of the present invention will be explained with reference to the drawings.

In FIG. 5, 13 is a square or rectangular heat exchange rod, which has a plurality of parallel flows 513a. 14 is a spacer having an airflow guiding function and a spacing maintaining function.

Further, in FIG. 1, reference numeral 15 denotes a tape-shaped material adhered to both ends of the heat exchange cord 13 in the parallel flow path direction and onto the spacer 14, and the tape-shaped material 15 exhibits an adhesive effect when pressurized or heated. It is something. .

In the above configuration, when constructing a heat exchanger similar to that shown in FIG. When the contact parts are pressurized or heated, each contact part is instantly bonded, making it very easy to assemble the heat exchanger.

〔Effect of the invention〕

As described above, in the present invention, the tape-shaped pieces of wood are bonded by applying pressure or heat to the overlapping parts of the heat exchanger cables and the mating parts of the heat exchanger cable spacers, which are alternately laid down. After providing the heat exchanger, the above-mentioned joint portion can be immediately corrugated by applying pressure or heating, which facilitates the manufacture of the heat exchanger.
