Spiral heat exchanger and heat exchange device

A spiral heat exchanger, characterized by comprising:

• a core shaft with an axis left-right extending, and
• a first liquid-passing coiled tape having a spiral shape, wound around the periphery of the core shaft for at least two circles, and having a first spiral liquid flow channel therein;
• a second liquid-passing coiled tape having a spiral shape, wound around the periphery of the core shaft for at least two circles, and having a second spiral liquid flow channel therein;
• adjacent circles of the first liquid-passing coiled tape is isolated by a certain distance, thereby forming a first airflow channel through left and right with a spiral shape;
• adjacent circles of the second liquid-passing coiled tape isolated a certain distance, thereby forming a second airflow channel through left and right;
• the first liquid-passing coiled tape is respectively provided with a first inlet/outlet liquid port and a second inlet/outlet liquid port connecting with each other by means of the first spiral liquid flow channel on the inner side end and the outer side end in its spiral direction, the second liquid-passing coiled tape is respectively provided with a third inlet/outlet liquid port and a fourth inlet/outlet liquid port connecting with each other by means of the second spiral liquid flow channel on the inner side end and the outer side end in its spiral direction.

• a core shaft with an axis left-right extending, and
• a first liquid-passing coiled tape having a spiral shape, wound around the periphery of the core shaft for at least two circle;
• adjacent circles of the coiled tape are isolated by a certain distance, thereby a spiral first airflow channel through left and right between the adjacent circles of the coiled tape;
• the first liquid-passing coiled tape includes a plurality of tape bodies having a spiral shape wound around the core shaft and having spiral liquid flow channel therein, the plurality of tape bodies are separately arranged parallel to each other in the radial direction of the core shaft, thereby forming a fourth airflow channel through left and right between the adjacent tape body.

A spiral heat exchanger, comprising:

• an internal supporting body, and
• a third liquid-passing coiled tape having a spiral shape wound around the periphery of the internal supporting body and having a liquid flow space of the third liquid-passing coiled tape therein;
• the axis for winding the third liquid-passing coiled tape extends in left-right direction, adjacent circle of the third liquid-passing coiled tape are isolated by a certain distance, thereby forming a third airflow channel through left and right;
• characterized in that,
• the liquid flow space of the third liquid-passing coiled tape includes 2N+2 sub-liquid flow channels spirally extending, the 2N+2 sub-liquid flow channels are arranged along left-right direction and sequentially connected with each other, where N is a natural number;
• in the 2N+2 sub-liquid flow channels, the sub-liquid flow channel on leftmost side has a first liquid inlet/outlet, and the sub-liquid flow channel on rightmost side has a second liquid inlet/outlet;
• the internal supporting body is provided with a third liquid inlet/outlet liquidly connected with the first liquid inlet/outlet and a fourth liquid inlet/outlet liquidly connected with the second liquid inlet/outlet.
