Claims

[Scope of utility model registration request]

(1) Construct a heat exchanger by spirally winding two strip-shaped heat exchanger plates parallel to each other with a gap between them, and close and seal both open ends of the heat exchanger with Kabani plates so that the heat exchanger can be placed inside the shell. In a spiral plate heat exchanger that forms two series of spiral flow paths in which a high-temperature fluid and a low-temperature fluid flow between heat exchanger plates, the inner surface of the cover plate corresponds to the heat exchanger plates. 1. A spiral plate heat exchanger characterized in that a spiral groove is formed, and seven side edges of a heat transfer plate are inserted into the groove to fix and support the heat transfer plate to a cover plate. .

(2) Utility Model Registration The heat exchanger according to claim 1 is characterized in that a gasket is provided at the bottom of the groove along the groove of the cover plate to seal between the cover plate and the heat transfer plate. Spiral plate heat exchanger.

(3) Utility Model Registration The spiral plate heat exchanger according to claim 1, characterized in that the spiral grooves are formed by cutting the inner surface of the cover plate.

(4) Utility model registration The heat exchanger according to claim 1, characterized in that a spiral groove is formed between two spiral strips welded to the inner surface of the cover plate. Spiral plate heat exchanger.
