It will be appreciated that a certain interval needs to be satisfied between the spraying system 2 and the surface air heater 1 to form a spraying space therebetween, so as to ensure that the atomized water droplets 4 formed by the spraying system can be fully mixed with air.
Preferably, the distance between the spraying system 2 and the surface-cooled heater 1 can be set between 10 and 50 cm.
Further, in this embodiment, the spraying system is pressurized with pure water. The pure water is used as a medium of the spraying system, so that the failure rate of the system can be reduced, and the system is more reliable.

And the micro-mist spray head arranged in the high-pressure spray section sprays high-pressure water to form micro-mist small water drops.
Alternatively, in another embodiment of the present utility model, the water atomization device 201 may also be implemented using an ultrasonic atomizer.
