The invention discloses a plate-shell type nonsaturated
evaporation condensing device comprising an upper housing body, a plate-shell type
heat exchanger, and a lower housing body. The upper housing body is connected with the lower housing body by a water pump, and the heat exchange main body is the plate-shell type
heat exchanger which is connected with the upper housing body and the lower housing body respectively. The plate-shell type
heat exchanger comprises an upper tube plate, a lower tube plate, heat exchange plate bundles, a housing, a baffle, a gas-distributing
pipe and a collector tube. The upper tube plate is provided horizontally, the lower tube plate declines in the direction of the flowing hot fluid, the plate type heat exchanger gets through holes in the upper tube plate and the lower tube plate with a in-line modus, and the baffle is disposed among the heat exchange plate bundles. The inventive device is provided with a large effective
heat transfer area, even aqueous film allocation, rapid
settling velocity, quick transfer of nonsaturated
evaporation heat and
moisture, anabatic liquid membrane fluctuation, enhanced turbulent flow, an attenuated liquid membrane laminar sublayer, decreased
heat resistance, a small condensing resisting force and a remarkable condensing effect. Deposit and
erosion are reduced, a mall floor space is provided, and the inventive device is suitable for condensing and cooling field.
