As shown in Figure 1, a kind of free convection cooling tower air cooling system described in the embodiment of the present invention, this system comprises free convection tower body 2, arranges multi-group heat exchanger and supporting mechanism 1 in described free convection tower body 2, and described multi-group heat exchanger comprises the tube bank case 5 of multiple connection; Wherein, each tube bank case 5 is the tube bank of many group fin tubuloses, and the tube bank of fin tubulose comprises tubulose finned tube, the lateral wall of tubulose finned tube is compounded with rolling radiating fin; The input interface of the tube bank case 5 of multiple connection is communicated with the inlet channel 7 of free convection tower body 2, and delivery port is communicated with the effluent pipe mouth of free convection tower body 2.
Preferably, this free convection cooling tower air cooling system also comprises the bracing frame 3 be arranged on below described free convection tower body 2, and be arranged in described free convection tower body 2 for supporting the pillar 4 of the tube bank case 5 of described multiple connection, this pillar 4 is connected with bracing frame 3, and bracing frame 3 supports above-mentioned water tank group.
Concrete, described radiating fin is spiral heat dissipation fin, for heat radiation, is communicated with between described tube bank case 5 by connecting water tank 6.
The cooling tower that the present embodiment provides decreases the waste of the energy by air heat-exchange, simultaneously by adopting fin to carry out heat exchange, increases heat exchange efficiency.Concrete:
The inlet channel 7 of each free convection tower body 2 and outlet pipe arrange stop valve and discharging valve.When certain free convection tower body 2 needs out of service or stoppage in transit maintenance, this section of inlet/outlet valve can be cut off, open discharging valve, the water of cooling tower be put into underground water storage tank, and does not affect the normal operation of other cooling section.
Recirculated water Inlet and outlet water house steward is radially laid in free convection tower body 2 subsurface, and every section of Inlet and outlet water vertical tube is connected with house steward respectively.To under platform on vertical tube, change into horizontal annular arm and be connected with each cooling triangle water inlet pipe and water outlet pipe.Each section of inlet/outlet valve and discharging valve are arranged in ground valve indoor.Respectively establish an expansion tank at outfall sewer two ends higher than cooling triangle top, change the use of system volume change and the micro-moisturizing caused in order to regulate circulating water temperature.
In free convection tower body 2 underground, storage cistern is set, with circulating cooling buffering and winter cooling section stop transport antifreeze and maintenance stoppage in transit emptying water storage.Establish between water storage tank between a underground type pump working, inside establish charging pump, small pump, underground water storage tank Level monitor etc.
