The invention relates to an ice
crystal evaporator and an ice
crystal water cooling device producing from the same, belonging to the technical field of
refrigeration. The ice
crystal evaporator is characterized in that a liquid
inlet channel is formed by an
evaporator tube, a liquid inlet and a liquid outlet in a tubular casing; and the outer channel of the evaporator tube of the tubular casing is divided into more than one S-shaped channel forming a water
return channel through a water inlet of a water divider and a water outlet of a water collector. The ice crystal
water cooling device is characterized in that the return air inlet of the ice crystal evaporator is communicated with a compressor, a condenser, a liquid feeding valve, a dry filter, a liquid feeding
electromagnetic valve anda thermostatic expansion valve in sequence, and then is communicated with the liquid inlet of the ice crystal evaporator; a cooling water inlet / outlet of the condenser is connected with a
cooling tower in series; and a water inlet / outlet of the ice crystal evaporator is communicated with a water
circulating pump and an ice crystal
energy storage tank in series. The invention has the advantages ofhigh
cooling efficiency, no
icing and low
cooling temperature and is suitable for production of
energy storage central air-conditioning, marine
fishing,
seafood processing, fruit, vegetable or meat
processing, and the like; the cooled medium is municipal water.
