By the discharge slowly of draining aperture, the cold water in water storage box can be supplemented to filling for water after absorbing heat in water-filling layer
In water layer, keeps the water temperature of water in water-filling layer will not be too high, enable water-filling layer constant absorption shell heat.
Further, the water outlet edge is equipped with the recess being embedded in for switchboard, and the switchboard, which is equipped with, to be used to be embedded in out
Protrusion in the mouth of a river.
Switchboard and water outlet can be made to fit together by setting recess and protrusion, enhance switchboard to water outlet
Leakproofness.
Further, the shell is bilayer, and the water-filling layer is the interlayer of shell.
Water-filling layer is the interlayer of shell, and water can be made directly to contact shell, enhances endothermic effect.
Further, the water-filling layer is the water pocket being placed on shell.
Water-filling layer is the independent water pocket with shell, can need to adjust position or the change water pocket of water pocket according to actual installation
Shape, be conveniently replaceable.
