とされている。(Prior Art) Fig. 5 shows a conventional heat transfer plate for a plate exchanger, and this heat transfer plate has circulation holes 1 at the four corners of the square shaped plate. A heat transfer portion 3 surrounded by a casket 2 is formed on the surface other than the surface Av. This heat transfer plate has the same shape as seen from the front side in FIG. 5, that is, when viewed from the front side, the back side has the opposite shape to the front side.

For example, the heat transfer plate shown in FIG.
On the second plate, the heat transfer brake I and the concave plate shown in Fig. 5 are assembled by rotating the plate 1801 times in one plane using the method shown in Fig. 5. In this order j'f-, the heat transfer plates are alternately folded together and sandwiched between one of the two side plates 6, 6 to form a flow passage between the opposing conductive portions 3, 3. In this case, C Nishikojiji is 614th, with the flow of 1 population H, the temperature is 11i, and the soul of arrow C is the low temperature fluid. configured to be traced.

Therefore, conventionally, the heat transfer plate has been made of a 1-4" curved lumber such as stainless steel, nickel alloy steel, or titanium alloy steel, which has excellent corrosion resistance.
しかしなから こうした材料を用いると耐食性番こつい
てはI]的を達成するか、伝熱プレート屯品としてかな

こうしたことに鑑み 本出願人は安価な伝熱プレートを

鋼板の表裏全体に耐食性確保のためにホーローをコーテ
ィングすることを試みた。In view of this, in order to provide an inexpensive heat transfer plate, the present applicant attempted to use a mild steel plate as the heat transfer plate itself and coat the entire front and back of the mild steel plate with enamel to ensure corrosion resistance.

問題がある。However, with the conventional heat transfer plate, as shown in Figure US7, an enlarged cross-sectional view of the vicinity of the LTC through hole l.
In order to ensure that all parts including the inner peripheral edge of the west through hole 1 are made of mild steel, if this mild steel plate is coated with enamel, the straight hole marked in white on either the through hole 1 or the heat transfer plate 11 will be removed. If this is the case, the boundary between the plate surface and the Jk through hole l will be in a shape that is straight (11). Although such a shape is cheap to manufacture, there is a problem in the following gap.
つまり 上記角ばった部分か存在すると、ホーローをコ

たままになることである。In other words, if the above-mentioned angular parts exist, even if the enamel is coated, the enamel layer will be attached to the inner peripheral surface of the flow hole 1 (the surface of the mild steel base material will remain exposed). be.
このように流通通孔1にホーロー層11が付きにくいと
、硫酸のような#食性のある流体を熱交換のために流通

ない。If the enamel layer 11 is difficult to adhere to the flow hole 1 in this way, when a fluid with corrosive properties such as sulfuric acid is passed through for heat exchange, the enamel layer 11 will not be present and the flow hole will have an exposed surface. This is not preferable because corrosion begins through the through hole 1.

In this way.

耐えられる。On the other hand, as shown in Figure A3, the enamel qtt is applied to the entire front and back of the heat transfer plate, and the enamel layer 11 is formed even on the front and back of the corrosion-resistant ring 1O. However, the inner peripheral wall of the flow hole 1 itself is a corrosion-resistant stainless steel surface as in the above embodiment, so the flow fluid may not be as corrosive as sulfuric acid. Even so, it is tolerable.
