[0001] The utility model relates to a cooling tower technical field, concretely relates to a kind of anti-icing cooling towers. BACKGROUND

[0002] Large cooling and heating system needs cooling water to maintain each unit to work at appropriate temperature when operating, and the cooling of cooling water is realized by small cooling tower, so the timely filling of cold air has great influence on the working efficiency of cooling tower.

[0003] In the vast northern region of China, due to the relatively low outdoor temperature in winter, when water droplets are splashed on the louvers of the cooling tower, ice source is easily formed, resulting in icing on the louvers. After the louvers freeze, the air duct will be blocked, reducing the air entering the cooling tower, thereby reducing the efficiency of the cooling tower.

[0004] In view of the problem that the louvers of the cooling tower are easy to freeze in winter, the utility model provides an anti-icing cooling tower. SUMMARY

[0008] Compared with the prior art, the utility model has the following beneficial effects: since the thickness of the tank body of the static pressure tank is greater than 200 mm, the water splashed from the filler in the tower generally falls only a few centimeters away, and it is difficult to fall on the louver assembly 200 mm away, thereby avoiding the freezing of the louver assembly. Of course, the thickness of the tank body of the static pressure tank can be adjusted according to the size of the cooling tower. If the cooling tower is higher, the splashed water falls farther, and the thickness of the tank body of the static pressure tank can be appropriately increased to ensure that the water does not fall on the louver assembly.

[0009] Further, the static pressure tank includes a top plate, a bottom plate, a left side plate and a right side plate, the top plate is inclined downward away from the cooling tower body, and the bottom plate is inclined downward towards the cooling tower body.

[0010] The beneficial effect of adopting the further technical scheme is that the top plate is outwardly inclined to guide the external rainwater away from the cooling tower, avoiding the external rainwater from entering the tower to cause temperature fluctuation in the cooling tower; and the bottom plate is inwardly inclined to recover the splashed water in the tower and reduce water loss in the tower.

[0011] Further, the louvre assembly comprises louvre columns and louvre blades, and the louvre columns are arranged in parallel.

[0012] Further, the louvre assembly is provided with a guard plate on both sides and the lower part.

[0013] The beneficial effect of adopting the further technical scheme is that the guard plate improves the firmness of the louvre assembly.

[0014] Further, the louvre assembly is provided with a column cross bracing plate, which is perpendicular to the louvre columns.

[0015] The beneficial effect of adopting the further technical scheme is that the column cross bracing plate improves the strength of the louvre columns, avoiding insufficient strength due to too high column height.

[0016] Further, the bottom plate of the static pressure tank is provided with a support plate.

[0017] The beneficial effect of adopting the further technical scheme is that the support plate improves the structural strength, avoiding deformation of the static pressure tank due to gravity.

[0018] Further, the louvre blades are inclined downward away from the cooling tower body.

[0019] The beneficial effect of adopting the further technical scheme is that the external facade of the cooling tower is beautiful, the wind guiding effect is achieved, and the intrusion of external rainwater and fallen leaves and other impurities into the tower body is effectively blocked, avoiding interference with the operation of the tower body.

[0020] Further, the side of the static pressure tank away from the louvre assembly is provided with a honeycomb water collector.

[0021] The beneficial effect of adopting the further technical scheme is that the external air is once guided by the louvre assembly, enters the static pressure tank, and then is twice distributed by the honeycomb water collector to enter the cooling tower, so that uniform and stable air flow is obtained, the heat exchange efficiency of the cooling tower is improved, the dynamic pressure loss is reduced, and the effect of reducing and weakening the ventilation noise is achieved.

[0022] Further, the top plate, the bottom plate, the left side plate and the right side plate of the static pressure tank are provided with sealing materials at the connection ends with the cooling tower body.

[0023] The beneficial effects of the further technical scheme are: ensuring the sealing of the box body, avoiding the internal water flow out, and avoiding the external water flow in. BRIEF DESCRIPTION OF DRAWINGS
