Description
【0001】[0001]
本考案は、流路用ガスケット部と通路孔用ガスケット部とをガスケット連結部 により連結したプレート積層型熱交換器用のガスケットに関する。 The present invention relates to a gasket for a laminated plate type heat exchanger in which a gasket portion for a flow passage and a gasket portion for a passage hole are connected by a gasket connecting portion.
【0002】[0002]
従来、図4乃至図6に示すプレート積層型熱交換器用のガスケットが知られて いるが、これは流体流路1を形成する伝熱面2の四隅に流体流路孔3を設けた伝 熱プレート4に嵌着され、かつ、流体流路1と流体通路孔3を夫々シールするガ スケット本体部5と通路孔ガスケット部6との間に形成される大気開放空間シー ル部9を有すると共に上記ガスケット本体部5と通路孔ガスケット部6とを、ガ スケット本体部5および通路孔ガスケット部6の厚みと略同一厚みで、かつ、上 記開放空間シール部9の近傍位置に配設した橋架部10で一体に連結したもので あって、橋架部10がガスケット本体部5と通路孔ガスケット6の厚みと略同一 厚みであるために、大気開放空間部7内に張り出し畝(うね)状を呈してシール 部からの漏洩流体の流出を悪化するという最悪の汚染要因を有していた。 Conventionally, a gasket for a laminated plate type heat exchanger shown in FIGS. 4 to 6 has been known. This gasket has a heat transfer surface in which fluid flow holes 1 are formed at four corners of a heat transfer surface 2. An air opening space sealing portion 9 formed between a gasket main body portion 5 and a passage hole gasket portion 6 fitted to the plate 4 and sealing the fluid passage 1 and the fluid passage hole 3, respectively; A bridge in which the gasket main body 5 and the passage hole gasket 6 are substantially the same thickness as the gasket main body 5 and the passage hole gasket 6 and are disposed in the vicinity of the open space seal 9. Since the bridge 10 is substantially the same thickness as the gasket main body 5 and the passage hole gasket 6, the bridge 10 is ridge-shaped in the open-to-atmosphere space 7. Leakage flow from the seal They had the worst of the pollution factors that worsen the outflow.
【0003】 そこで、本考案者は、橋架部を約半分の厚さとすることで、上記畝状張り出し 部を無くして、上記汚染要因を解消することを試みた。 しかし乍ら、これには橋架部(本考案の連結部に相当する)が半分の厚さとな ったために捻転を起り易くなって、当該捻転が流れ妨げて汚染を惹起する原因と なる不都合があることが判明した。[0003] Therefore, the present inventors have tried to eliminate the above-mentioned pollution factor by eliminating the ridge-like overhanging portion by making the bridge portion approximately half the thickness. However, this has the disadvantage that the bridge (corresponding to the connecting portion of the present invention) has a half thickness, so that it is easy to twist, and the twist prevents flow and causes contamination. It turned out to be.
【0004】 そこで、更に本考案者は上記不都合を解消するために試行錯誤し、本考案を案 出することができたものである。Therefore, the present inventor has been able to devise the present invention by trial and error in order to solve the above inconvenience.
【0005】[0005]
