Spray-type Heat Exchanger Shell and Tube
Water Cooling Evaporator
Falling film refrigerant sprayed on the brass, the use of copper fins to produce Gerry Valley benefits.
Improve the heat transfer coefficient. Falling film type than the full liquid heat transfer efficiency,
refrigerant use less.
Falling film heat transfer efficiency is high. Falling film evaporation is flow boiling, because the outer
surface of the liquid film layer thickness is small, no hydrostatic pressure generated by the high heat
transfer coefficient.
And the full-liquid evaporation (that is, immersion evaporation) generated bubbles easily gathered in the
surface of the heat transfer tube, resulting in decreased heat transfer efficiency, the heat transfer effect
as falling film evaporation. In general, falling film evaporation is a small temperature difference, but to
prevent scaling, affecting heat transfer efficiency.
"Falling film" of a shell and tube evaporator. Its "shell" inside the refrigerant cycle, "pipe" to take the chilled
water cycle, from the profile point of view, as if there are half of the cylinder tube refrigerant, and the water
pipe bundle soaked in the refrigerant.
It is the opposite of the "dry evaporator", dry type is "pipe" to take the refrigerant, "shell" water, like the
refrigerant tube soaked in water.
