Abstract
The present application relates to a spiral heat exchanger and a heat exchange device. The spiral heat exchanger comprises: a core shaft with an axis extending in the left-right direction; a first liquid-passing coiled tape with a spiral liquid flow channel therein wound around the axis of the core shaft at least two circles to form a spiral shape; and seal strips sealed between the sides of two heat conduction thin tapes and the spiral liquid flow channel formed between the seal strips and between the two heat conduction thin tapes, wherein adjacent circles of the first liquid-passing coiled tape is isolated by a certain distance maintained by a duct support to prevent the adjacent circles from sticking to each other to create a blockage in the spiral airflow channel.
