Problems solved by technology

However, in the heat exchanger described in Patent Document 7, since a water-based adhesive is used to fabricate a total heat exchange element by laminating a predetermined number of element constituent units, water-soluble moisture absorbing agent flows from the partition member to the heat exchanger at this time. The transfer of the spacer maintains the part, and the partition part cannot maintain the moisture permeability when the partition part is alone in the stage of assembling to the total heat exchange element, and the latent heat exchange efficiency decreases

Embodiment approach 1

[0043] figure 1 It is a perspective view which schematically shows an example of a total heat exchange element. The total heat exchange element 20 shown in this figure is a cross-flow type total heat exchange element having a laminated structure in which sheet-like partition members 1 and corrugated plate-shaped spacer members 5 are alternately laminated. In this total heat exchange element 20, the above-mentioned laminated structure is formed by laminating six element constituting units 10a to 10f, and the top plate member 15 is further laminated on the uppermost element constituting unit 10f. The corrugations of the spacer 5 in one element constituting unit are substantially perpendicular to the corrugations of the spacer 5 in the element constituting unit above or below it when viewed from a plane. In other words, the longitudinal direction of the peaks or valleys in the corrugated plate-shaped spacer 5 in a certain element constituting unit is different from the longitudi...

[0081] For the bonding of the partition member and the spacer in each element constituting unit of the total heat exchange element, or the bonding of the element constituting units, the spacer can also be formed by the base material and the thermal adhesive resin layer, and the spacer can be formed by forming the spacer. The heat-adhesive resin layer of the holding member is used as an adhesive. The overall shape of the total heat exchange element having this joint form can be formed to match the figure 1 The shown total heat exchange elements 20 have the same overall shape, so illustration thereof is omitted here.

[0082] Figure 7 It is a cross-sectional view schematically showing a joint portion of one element constituting unit and an element constituting unit above it in an example of a total heat exchange element having the above-mentioned joining form, and its vicinity. This figure shows an element constituting unit 40a and an element constituting unit 40b bonded ther...

[0090] First, as the raw material of the partition member, a specially processed paper obtained by crushing and processing cellulose fibers (slurry) with a thickness of about 300 μm and an air permeability of 5,000 seconds or more is used to impregnate a predetermined amount of lithium chloride as a water-soluble hygroscopic agent. As the raw material for the spacer, a long piece of white single-sided glossy high-quality paper with a thickness of about 80 μm is used. image 3 The apparatus 120 shown is the same apparatus for making the long dimensions of the element-constituting unit material. At this time, as an adhesive for mutually joining the corrugated plate-shaped molded product obtained by forming the raw material of the spacer member formed by a corrugator and the raw material of the above-mentioned partition member, EVA ( Ethylene-vinyl acetate copolymer resin) is a hot-melt adhesive, and the molten product obtained by heating the hot-melt adhesive to about 150°C is a...

Abstract

In the manufacturing of a total heat exchanger element of laminate structure composed of, alternately superimposed, sheet-shaped partition members having a water-soluble moisture absorbent added thereto and spacing members bonded with an adhesive to the partition members so as to provide a gas stream channel in cooperation with the partition members, water retentivity is imparted to the spacing members, and an adhesive being insoluble in the water-soluble moisture absorbent or aqueous solutions of the water-soluble moisture absorbent is used as the above adhesive. Accordingly, it can be facilitated to obtain a total heat exchanger element that facilitates buildup of, for example, a ventilator or air conditioner of high reliability realizing a high latent heat exchange efficiency.

Description

technical field [0001] The present invention relates to a heat exchanger for constituting an air conditioner or a ventilator, a total heat exchange element for performing latent heat exchange and sensible heat exchange between two air streams, and a manufacturing method thereof, and more particularly relates to a heat exchanger for a stationary type A total heat exchange element of a heat exchanger and a method of manufacturing the same. Background technique [0002] There are two types of heat exchangers that constitute air conditioners or ventilation devices, such as rotary and stationary types. In any type of heat exchanger, it is suitable to use sensible heat exchange elements that have a higher heat exchange efficiency than only sensible heat exchange. High total heat exchange element. In most cases, the total heat exchange element uses a single-layer corrugated board manufacturing machine (single-sided layer device) to make a long-sized piece with a structure of a she...
