Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
Fig. 1 show one example structure schematic diagram of the utility model.As shown in Figure 1, the present embodiment includes hot water inlet pipe
(1)；Division box (2)；Filler (3)；Tank (4)；Air inlet (5)；Check valve (6)；Return pipe (7)；Water inlet branched pipe
(8)；Motor-driven valve (9)；Heat exchanger (10)；Return branch (11)；Measuring wind speed instrument (12)；Temperature sensor (13)；Wind turbine
(14)；Cooling tower ontology (15)；Motor-driven valve (16)；Temperature sensor (17).
The hot water inlet pipe 1, motor-driven valve 16, division box 2, filler 3, tank 4, check valve 16, return pipe 7, temperature
Sensor 17 constitutes open type cooling line.Hot water inlet pipe 1 is connected by more than 16 division box 2 of motor-driven valve, needs cooled water
It is entered in filler 3 from the spray of division box 2, the water being cooled in filler 3 is flowed into tank 4, and the water of tank 4 passes through
Check valve 6 enters in return branch 7；
The water inlet branched pipe 8, motor-driven valve 9, heat exchanger 10, return branch 11 constitute enclosed cooling line.Into water branch
Pipe 8 is connect by motor-driven valve 9 with heat exchanger 10, and the outlet of heat exchanger 10 is connect with return branch 11, and return branch 11 is by electronic
Valve 9 is connect with return pipe 7.
The wind turbine 14, air inlet 5 constitute forced ventilation.
Among the above, by detecting environment temperature, cooling line (open type cools down and enclosed cooling) and cooling side in cooling tower
Formula (gravity-flow ventilation and forced ventilation) can be with switchover operation.
As shown in Figure 1, when photo-thermal power generation operation on daytime, load is larger, opens motor-driven valve 16 at this time, closes motor-driven valve 9,
Cooled water is needed to be entered in division box 2 by hot water inlet pipe 1, by the spray to filler 3 of division box 2, filling out
Water comes into full contact with heat exchange with air in material 3, and cooled water is flowed into tank 4, and return pipe is being entered by check valve 6
In 7；When temperature sensor 13 detects that environment temperature exceeds design temperature and temperature sensor 17 detects that return water temperature is higher
When, wind turbine 14 is opened, and wind is entered from ventilation opening 5 in cooling tower, realizes forced ventilation.Temperature sensor 13 detects environment temperature
When degree changes to lower, the rotating speed of wind turbine 14 is lower therewith, reaches energy-efficient effect.
As shown in Figure 1, when photo-thermal power generation runs night, load is smaller, and temperature sensor 13 detects that environment temperature is low
When, motor-driven valve 16 is closed, motor-driven valve 9 is opened.Need cooled water by water inlet branched pipe 8, motor-driven valve 9, into heat exchanger
By air cooling in 10, water after cooling is entered by return branch 11, motor-driven valve 9 in return pipe 7, and check valve 16 can be with
Water is prevented to flow back into tank 4.When temperature sensor 17 detects that return water temperature is higher, wind turbine 14 is opened, and wind is from air inlet
Mouth 5 enters in cooling tower, realizes forced ventilation, the heat exchange of enhancing and heat exchanger 10.Since air is not in direct contact with water,
Therefore there is no water evaporation loss.Temperature sensor 13 detect variation of ambient temperature to it is lower when, the rotating speed of wind turbine 14 becomes therewith
It is low, reach energy-efficient effect.
