Countercurrent flow heat exchange fan coil device

The utility model relates to a fan coil device for countercurrent flow heat exchange, which comprises a condensation water disc, a countercurrent fin coiled pipe heat exchanger, a fan and a ventilation volume channel, and the countercurrent fin coiled pipe heat exchanger is integrally nested by a group of fins after at least two groups of coiled pipes are horizontally arranged and overlapped at intervals up and down; the end, close to the air outlet, of each set of coiled pipes is a coiled pipe medium f inflow port, the end, close to the air inlet, of each set of coiled pipes is a coiled pipe medium f outflow port, each set of coiled pipe medium f inflow port is communicated with the flow dividing header pipe, each set of coiled pipe medium f outflow port is communicated with the flow converging header pipe, and an exhaust valve is arranged at the top of the flow converging header pipe. The reverse-flow fin coiled pipe heat exchanger is integrally placed in a ventilation volume channel, and an air inlet of th
