The specific embodiment
The present invention is described further below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2, evaporation water compensating device of the present invention, comprise rotary body 2 and at least one water storage mozzle 1 that radially is arranged on the rotary body 2 and has shower nozzle 8, be connected with the intake tunnel 5 that is communicated with water storage mozzle 1 on the described rotary body 2, water storage mozzle 1 forms the surfaces of revolution 7 when rotating with rotary body 2, and the nozzle of described shower nozzle 8 is towards the side zones of the described surfaces of revolution 7.This evaporation water compensating device is when moisturizing, evaporating heat exchanger is arranged in the side zones of the surfaces of revolution 7, water storage mozzle 1 is that axis carries out circular motion with the axial line 6 of rotary body, realization is carried out periodic moisturizing to the metal surface of evaporating heat exchanger, therefore necessary time and space have been stayed for evaporation process, improved the environment of metal surface generation water evaporates effectively, made the efficient of evaporation and heat-exchange be able to tangible raising.Should be noted that, with water storage mozzle 1 radially be arranged on structure on the rotary body 2 not only comprise when water storage mozzle 1 axially with the axial perpendicular situation of rotary body 2, the situation when also comprising the certain angle of axial existence when the axial and rotary body 2 of water storage mozzle 1.Because, in both of these case, water storage mozzle 1 axially with rotary body 2 axial between projection on rotary body 2 cross sections be vertical all the time.
