A full -type evaporator

The utility model relates to a full -type evaporator, including the end plate, the barrel, evaporator tube bank, outlet duct and feed liquor device, the constitution enclosure space is connected to end plate and barrel, evaporator tube bank and end plate connect or welded fastening through rising, it separates into first evaporation district and second evaporation district with evaporator tube bank still to be equipped with first panel beating in the barrel, the barrel top is arranged in to the outlet duct level, the side board of intaking digs the hole, the outlet duct digs from the side board of intaking that stretch out in the hole and welded fastening in by the barrel, the feed liquor device is close to inside and outside the one end intercommunication barrel of the side board of intaking at the barrel, and the part of feed liquor device in the barrel is in first evaporation district top. After adopting such design, first panel beating carries out the subregion to evaporator tube bank, guarantees that there is higher heat exchange coefficient in the first evaporation district under the low heat transfer difference in temperature, and the refrigerant carries out the countercurrent flow with rivers are reverse, makes water temperature field and refrigerant concentration field reverse, and the temperature flows to low from the height, and oily concentration is from low mobile to the height, the heat exchange efficiency height, and energy -conservation, economy are reliable again.
