The invention relates to a cooling water tower, in particular to a fog-eliminating cooling water tower for a cross-flow air conditioner.

The operating principle of the cross-flow air-conditioning cooling water tower in the prior art is that the circulating water passes through the heat source device and then enters the cooling water tower. The cooling system uses evaporation to dissipate heat, and the evaporated water vapor is drawn away by the fan located above to take away the heat, and the cooled water drops into the water pan and is re-transmitted to the heat source device for cooling.

However, when the hot and humid water vapor is extracted from the cooling water tower to the outside, a large amount of white smoke will be produced. The physical phenomenon caused by condensation, although the generation of white smoke has no effect on the use of the cooling tower itself, it has a great impact on the surrounding factory area, working environment, road traffic sight and the loss of circulating water; Therefore, the cross-flow air-conditioning cooling water tower of the prior art has the aforementioned problems and shortcomings in its overall structure, and it really needs to be improved.

Please refer to Figures 1 to 3, the sprinkler assembly 40 includes a water tank 41, a plurality of low-level sprinklers 42, a plurality of high-level sprinklers 43 and a rotating shaft 44, and the water tank 41 is arranged in the body 10 and located in the heat sink assembly. 20, the water tank 41 is connected to the aforementioned cooling water circulation device 50, and each low sprinkler 42 has a low water inlet 421 and is assembled at the bottom of the water tank 41, and the low water inlet 421 and the water tank 41 Connected and flush with the tank bottom of the water tank 41, the lower sprinkler 42 is a standard component of the prior art, and its detailed structure will not be repeated. Location.

Each high-level sprinkler 43 includes a lower pipe 431, an upper pipe 432 and an eccentric rod 433. The lower pipe 431 is a hollow pipe body and is fixed on the bottom of the water tank 41. One end of the upper pipe 432 is a middle The empty pipe body is provided with a seal 434, and the other end of the seal 434 has a high water inlet 435. The high water inlet 435 communicates with the water tank 41 and keeps a distance from the bottom of the water tank 41. The upper pipe 432 is adjacent to the high-level water inlet 435, and a connecting portion 436 is protrudingly provided. The connecting portion 436 runs through a connecting hole. The upper pipe 432 is installed in the lower pipe 431 and the sealing member 434 is attached to the inner pipe wall of the lower pipe 431. The upper pipe 432 can move axially relative to the lower pipe 431. One end of the eccentric rod 433 is a connecting rod 437, and the connecting rod 437 runs through a connecting hole. The connecting hole is aligned with the connecting hole of the connecting part 436 and connected by a bolt. The other end of the eccentric rod 433 is an eccentric wheel 438 , and an eccentric hole runs through the eccentric wheel 438 , and the high-level sprinklers 43 are arranged at intervals and aligned with the position of the heat sink 21 in the first zone.

The rotating shaft 44 is a rod body and is bent to form a plurality of eccentric shafts 441. The axes of each eccentric shaft 441 are parallel to the axis of the rotating shaft 44. The structure of the eccentric shaft 441 is a prior art, so it will not be described in detail. The rotating shaft 44 can rotate The ground is assembled on the body 10 and each eccentric shaft 441 passes through each eccentric hole of each high-level sprinkler 43. In this embodiment, the rotating shaft 44 is connected with a driving device (not shown in the drawing), and the driving device is used to drive the rotating shaft. 44 rotations, the driving device is a motor, but not limited thereto, any mechanism that can drive the upper section pipe 432 to produce up and down displacement relative to the lower section pipe 431 to change the height of the high water inlet 435 is all right.

When the present invention is in use, it has a summer operation mode and a winter operation mode, as shown in Fig. 4 and Fig. 5. In the summer operation mode, due to the high demand for heat dissipation, the cooling water circulation device 50 will automatically increase the cooling cycle. The amount of water in the circle, the liquid level in the water tank 41 will rise and cover the high-level water inlet 435 so that the upper pipe 432 will enter the water, and the heat sink 21 in the first zone will be sprayed by the water from the high-level sprinkler 43. The heat sink 22 will be sprayed by the water from the lower sprinkler 42, and the cold air flowing in from the side opening 12 will cool down the water sprayed on the heat sink 21 in the first area and the heat sink 22 in the second area, and will be cooled by the fan 30. It is drawn out of the main body 10. Although the hot and humid air extracted has high absolute humidity, the hot and humid air will not reach the dew point because of the high temperature of the external environment, so the phenomenon of fogging can be avoided. During the aforementioned process, the driving device ( (not shown in the drawings) rotate the rotating shaft 44 to make the upper pipe 432 move in the lower pipe 431, adjust the high water inlet 435 to an appropriate height to control the amount of watering, and achieve the effect of accurately controlling the air humidity after mixing, and The cooled water that falls into the lower sump 13 then flows to the external device (not shown in the drawings) to dissipate heat.

Please refer to Fig. 1 and Fig. 2, during the winter operation mode, since the cooling water circulation device 50 will automatically reduce the water volume of the cooling water circulation, the liquid level in the water tank 41 will be reduced and lower than that of the high water inlet 435. At this time, the high-level sprinkler 43 has no water entering from the high-level water inlet 435, so there is no water to spray the heat sink 21 in the first zone, so the moisture content of the cold air flowing in from the outside does not increase after passing through the heat sink 21 in the first zone, only The air in the heat sink 21 of the first area conducts heat transfer with the water adjacent to the heat sink 22 in the second area to increase the temperature of the air. Since water enters the low-level water inlet 421, water will be normally sprinkled on the heat sink 22 in the second area. The cold air flowing in exchanges heat with the water on the cooling fins 22 of the second zone to form hot air with higher humidity, and the hot air with higher humidity mixes with the air passing through the cooling fins 21 of the first zone and is pumped by the fan 30 to Externally, due to the low relative humidity of the mixed air, the water vapor that does not exceed the saturation line of the humid air cannot condense into liquid droplets, so the phenomenon of fogging can be avoided.

In the aforementioned process, the overall relative humidity of the air after mixing with the hot and humid air of the cooling fins 22 in the second area is reduced by controlling the amount of water sprayed by the cooling fins 21 in the first area and increasing an appropriate amount of dry and cold air with low relative humidity. After the mixed air is extracted from the fan 30 to the outside and mixed with the outside air, although its temperature is lowered, due to the low relative humidity of the air, the mixed air will not reach saturation in this state, so the phenomenon of fogging can be avoided the goal of.
