SPIRAL HEAT EXCHANGER AND HEAT EXCHANGE DEVICE

The present invention application relates to a spiral heat exchanger and a heat exchange device. The spiral heat exchanger comprises: a core shaft (1), the axis of which extends in the left-right direction, a first liquid-passing coiled tape (2) spirally wound around the periphery of the core shaft (1) by at least two circles and having a spiral liquid channel (201) therein; the first liquid-passing coiled tape (2) of adjacent layers is isolated by a certain distance, thereby forming a left-right through spiral first air flow channel (3); the first liquid-passing coiled tape (2) is provided with first liquid inlet/outlet ports (4) and second liquid inlet/outlet ports (5) which are arranged at intervals along the length direction of the liquid-passing coiled tape (2) and communicated with each other by means of the spiral liquid channel (201); the first liquid inlet/outlet ports (4) are arranged at the inner side end of the first liquid-passing coiled tape (2) in the spiral direction and extend out of the left side in a direction parallel to the axis of the core shaft (1); the second liquid inlet/outlet ports (5) extend out of the right side in a direction parallel to the axis of the core shaft (1).
