As a further improvement on the present invention, described fan house is positioned at air draft tube bottom also partially in a side, and the top surface of fan house is the ladder inclined-plane that is reduced gradually by a side direction opposite side.
As a further improvement on the present invention, under the described vaporation-type coil pipe, be provided with filler in the space directly over the water receiving tank.
As a further improvement on the present invention, the version of described filler is honeycomb fashion.
As a further improvement on the present invention, be provided with dehydrator in the space under described spray thrower top, the dry type fin cooling coil.
As a further improvement on the present invention, described water receiving tank is provided with water supplement port, overfall and sewage draining exit.
The present invention compared with prior art, advantage is:The present invention is simple in structure, and is reasonable in design, and the dry type fin cooling coil in the coil system carries out the heat radiation first time to the hot fluid that enters coil system, and then it is interior by shower water and cold dry air cooling to enter the vaporation-type coil pipe, has improved cooling effectiveness greatly; By blower fan is arranged in the air draft tube, make that the volume of whole cooling system is very light, be convenient to install setting; By in the air draft tube, having increased filler, prolong the cooling water time of staying in addition, increased heat exchange area, increased the heat exchange amount, improved cooling effect.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the dual-cooling type closed cooling system among the embodiment mainly is made up of parts such as air draft tube 1, blower fan 2, water receiving tank 3, spray pump 4, circulation line 5, filler 6, coil system 7, spray thrower 8 and dehydrators 9.
As shown in Figure 1, described air draft tube 1 one sides are provided with air inlet, and described blower fan 2 is installed in the air inlet place, is provided with fan house in the described air draft tube 1, and described blower fan 2 is installed in the fan house, and the air inlet of blower fan 2 and air draft tube 1 external communications are used for feeding cold dry air; Air draft tube 1 top is provided with ventilation window; Described coil system 7 is arranged in the air draft tube 1, and the hot fluid import 7a of coil system 7 is last, and cold fluid outlet 7b is following; Described coil system 7 comprises dry type fin cooling coil 7.1 and vaporation-type coil pipe 7.2 two parts, described dry type fin cooling coil 7.1 is arranged on the topmost in the air draft tube 1, described spray thrower 8 is arranged under the dry type fin cooling coil 7.1, and described vaporation-type coil pipe 7.2 is arranged under the spray thrower 8; Described air draft tube 1 bottom is provided with water receiving tank 3, and described water receiving tank 3 bottoms one side is provided with discharge outlet, and discharge outlet is connected with the water inlet of circulation line 5 with spray thrower 8 by spray pump 4; Described filler 6 is arranged under the coil system 7, in the space directly over the water receiving tank 3, filler 6 can prolong the cooling water time of staying, increases heat exchange area, increases the heat exchange amount.In the embodiment of the invention, the version of described filler 6 is honeycomb fashion.
