Specific implementation mode
The structural principle and operation principle of the present invention are described in detail below in conjunction with the accompanying drawings：
The cooled fluid of closed cooling tower flows in heat-exchanging tube bundle, and shower water as cooling fluid follow in tower
Ring is transmitted to the shower water outside wall surface through wall surface, then heat is transmitted to air by evaporative heat loss and contact heat dissipation by shower water, from
And achieve the purpose that cooling.Shower water eventually falls into the cistern 4 of bottom of tower, is recycled next time, and has ball-cock assembly to control water
Position, moisturizing is carried out to it.The cooled water or cooled medium of closed cooling tower in Bottomhole pressure, deposit by avoidable open cooling tower
Various problems influence, thus more and more applied.Requiring cooled water cleanliness factor height or air pollution tight
The occasion of weight, closed cooling tower can be matched in the intermediate frequency of central air-conditioning, instrument and meter, metallurgy at necessary and suitable selection
Electric furnace, converter, the generating set of power plant, Steam Turbine nuclear power station, substation, chemical industry, pharmacy, welding, aluminum, copper foil are with cold
But the industry manufacture fields such as hydraulic oil of oil, large-sized hydraulic press tool use.
Wherein, with the flow direction of water at cross is intersected, i.e. flow is fallen the wind of cross flow cooling tower from tower upper vertical, empty
For gas bottom horizontal flow sheet by packing, air-flow is orthogonal with flow.Cross flow cooling tower be by outside air from cooling tower side into
Enter unit, unit is discharged upwards after flowing transversely through filler and cooler, with spray water flow to intersecting vertically, the stream in cooling coil
Body medium.Cooling water carries out caloic with the outer spray water and air of pipe by coil pipe and exchanges, and it is direct with air to avoid cooled water
Water pollution caused by contact.Due to thering is the shower water precooled by PVC fillers, heat transfer effect to be substantially better than sky outside pipe
Cooler.It is such as used for refrigerator heat dissipation of terminal, the cooling coil 3 of cooling tower and the heat exchanger of refrigerator to link together, and are formed
One closed circulatory system, it is therefore prevented that the corrosion to the circulatory system such as sulfide gas, dust, microorganism in air, and
And the heat exchange of refrigerator will not form incrustation scale, eliminate the scale removal maintenance of refrigerator, so that refrigerator is economized on electricity, service life increases
It is long.
In the relative direction, i.e., flow is vertically fallen out of tower for the wind of counterflow cooling tower and the flow direction of water, airflow direction with
Water (flow) direction is opposite.The air inlet form of adverse current closed type cooling column be bottom adverse current enter the wind, under the action of air-introduced machine with flow shape
At forced convertion, it is inversely alternatively formed saturation damp-heat air with the shower water of whereabouts, heat is discharged by top wind turbine, and moisture is by taking off
Hydrophone keeps off back catch basin recycling, and inner space is not pre-chilled the filler or a small amount of filler of setting of heat dissipation, it is remaining go out more skies
Between increase the unit heat dissipation area of cooling coil 3, it is compact-sized, take up little area.It is relatively low or the temperature difference is smaller especially suitable for temperature
Fluid cooling.
