[0041] Below, refer to Figure 1 to Figure 8 , the heat exchanger according to the first embodiment of the present invention will be described. The heat exchange laminated body 11 is formed by laminating a plurality of heat transfer sheets 16 such as aluminum sheets. In addition, the heat exchange laminated body 11 is assembled to a casing by bolts, rivets, etc., and the casing is composed of a metal corner member 12 , a top plate 13 , and a bottom plate 14 . In addition, as the heat transfer sheet 16, in addition to using an aluminum sheet, especially when the air for heat exchange contains corrosive substances, an aluminum sheet or a stainless steel sheet with a corrosion-resistant coating can also be used. Corrosive sheet metal.

[0042] figure 2 A schematic diagram of the heat exchange stack 11 is shown. The airflow A of the return air and the airflow B of the external air are completely isolated by the heat transfer fins, and no gas transfer occurs. In addition, if ...

[0053] Figure 9 Heat exchangers of other embodiments are shown. This heat exchanger is a cross-type heat exchanger in which flat heat transfer fins and corrugated heat transfer fins as spacers are alternately laminated so as to be perpendicular to each other. Also in this heat exchanger, as in the above-mentioned first embodiment, the unvulcanized rubber 18 provided between the heat exchange laminate 11 and the corner member 12 is heated to ensure an airtight state.

[0054] In addition, although in the above-mentioned first embodiment, the notch of the joint portion between the corner member 12 and the corner portion of the heat exchange stacked body 11 is formed as Figure 10 The shape shown in (a), but not limited thereto, can be formed as Figure 10 Various shapes shown in (b) to (f) in the figure. In addition, shapes other than the above-mentioned shapes may be appropriately employed.

[0055] The heat exchanger of the present invention is produced by the above metho...

Abstract

The invention provides a heat exchanger which can perform heat exchange too in occasions where silicon-containing materials cannot be used. A corner member (12), a top plate (13) and a bottom plate (14) fix a heat exchange laminating body (11). Unvulcanized rubber mixed with a vulcanizing agent is inserted into a joint part between the corner member (12) and the corner portion of the heat exchange laminating body (11). The unvulcanized rubber is heated, so that the unvulcanized rubber is vulcanized to form, so that the rubber is expanded. Therefore, the airtightness keeping effect of the heat exchanger can be improved within a short time, and the heat exchanger can be easily manufactured, namely, the heat exchanger can be used too in a coating plant where silicon-containing materials cannot be used.

Description

technical field [0001] The present invention relates to static heat exchangers and methods for their manufacture. Background technique [0002] When ventilating a drying furnace, etc. in a factory, if the heat of the exhaust gas discharged from the drying furnace, etc. is recovered by a heat exchanger, energy loss can be reduced, and the energy-saving effect can be improved. That is, heat exchange is performed between high-temperature exhaust gas such as a drying furnace in a factory and normal-temperature air such as outside air, and the temperature-raised outside air is supplied to the drying furnace, thereby saving energy for heating the outside air. . [0003] As such heat exchangers used in factories or machines, it is preferable to use a cross-type heat exchanger in which aluminum heat transfer sheets are laminated in consideration of heat recovery efficiency. As such a heat exchanger, a heat exchanger in which rectangular heat transfer sheets are stacked is known, a...
