Wherein, the refrigerating machine 1, the cooling water pump 2 and the cooling tower are connected through a cooling water pipeline through which cooling circulating water flows. The refrigerator 1 continuously releases heat to the cooling circulation water, so that the temperature of the cooling circulation water increases. The cooling water pump 2 pumps the cooling circulation water with the increased temperature to the cooling tower water distribution disc 3. The cooling circulating water in the cooling tower water distribution disc 3 flows into the cooling tower filler 4 through the water distribution holes in the water distribution disc 3 under the action of gravity. And starting a fan of the cooling tower to ensure that the cooling circulating water flowing through the filler is subjected to total heat exchange with the outdoor air at the filler. The temperature of the air after heat exchange is increased, and the humidity is increased. The temperature of the cooling circulating water after heat exchange is reduced, the cooling circulating water passes through the water collecting tray 5 of the cooling tower and flows back to the refrigerator 1 again, and the refrigerator 1 is used for reducing the temperature and exchanging heat of the indoor air, so that the continuous and stable refrigeration work of the refrigeration system is realized.
The more uniform the water distribution in the water distribution tray 3 of the cooling tower is, the more sufficient the heat exchange between the cooling circulating water and the outdoor air is, the higher the temperature of the cooling circulating water is, and the more favorable the operation energy efficiency of the refrigerating machine is. In some refrigeration systems, because the cooling water pump 2 operates in a frequency conversion manner, the cooling water amount is less than the rated cooling water amount, so that only water is distributed near a water inlet in the water distribution disc 3 of the cooling tower, and water is not distributed in other areas of the water distribution disc 3, so that the heat exchange between air and the cooling water is uneven, and the energy efficiency of the refrigerator is influenced.

As shown in fig. 2 and 3, the cooling tower water distribution tray of the present embodiment includes a bottom wall having a water outlet and a side wall 31 enclosed along a circumferential direction of the bottom wall, and the bottom wall includes a bottom wall body 32 and at least one protrusion 34 protruding upward relative to the bottom wall body 32.
The bottom wall of the water distribution plate of the cooling tower of the embodiment comprises the convex part 34, so that under the flow of partial load cooling water, the cooling water is preferentially distributed on the bottom wall body 32 which is at a lower position than the convex part 34, and uniform water distribution is realized. The uniform water distribution can increase the heat exchange area of the cooling water and the filler, thereby improving the refrigeration effect of the refrigerator.
The bottom wall body 32 of the present embodiment is uniformly provided with a plurality of first water outlets 33.
The boss 34 of the present embodiment is a case that protrudes upward from the bottom wall body 32, and the outer surface of the case is a curved surface. The outer surface of the shell is provided with a curved surface, and the curved surface is convenient for cooling water to flow downwards to the filler along the curved surface when passing through the bulge part 34, so that uniform water distribution is realized. The curved surface can be a conical surface, a spherical surface and the like.
Specifically, in this embodiment, the curved surface is a hemispherical surface.
The bottom wall of this embodiment comprises at least one raised portion 34 arranged uniformly. As shown particularly in fig. 2, the at least one raised portion 34 of the present embodiment is spaced apart within the bottom wall.
The height of the protrusion 34 of this embodiment is less than the height of the water level of the water distribution tray at maximum load. That is, when the cooling tower water distribution tray of the present embodiment is at the full water level, the protruding portion 34 needs to be submerged in the cooling water.
When the flow rate of the cooling water is increased to raise the water level and partially immerse the protrusions 34, in order to enable the corresponding portions of the protrusions 34 to output the cooling water to further improve the heat exchange effect between the cooling water and the filler, a plurality of second water outlets 35 are uniformly formed on the surfaces of the protrusions 34. When the cooling water passes through the surface of the protruding portion 34, the cooling water flows to the lower packing through the second water outlet 35 under the action of gravity to exchange heat with the external air. To sum up, the water distribution plate of the cooling tower water distribution plate of the embodiment enables the water distribution plate to distribute water uniformly under the condition of different water inflow, so that the cooling tower filler can be uniformly wetted, and the cooling efficiency of the cooling tower filler is improved to enable the refrigerating unit to have higher energy efficiency.
In the present embodiment, the outer surface of the convex portion 34 is a hemispherical surface. In the embodiment, some of the second water outlets 35 in the second water outlets 35 are uniformly distributed around the central axis of the hemispherical surface along the circumferential direction. In the water distribution tray of the present embodiment, the cooling water covers the bottom wall body 32 completely when the flow rate of the cooling water is the lowest. Since the second water outlet 35 is also disposed on the protruding portion 34 of this embodiment, when the water level of the cooling water in the water distribution tray gradually increases, the number of the water outlets in the working state also increases, and therefore the water distribution tray of the cooling tower of this embodiment can automatically adjust the water amount of the water outlets under the condition of different water inflow.
As shown in fig. 2, the water distribution tray body of the present embodiment has a square structure.
The structure of the cooling tower water distribution plate according to an embodiment of the present invention will be described in detail with reference to fig. 2 and 3.
As shown in fig. 2, the cooling tower water distribution tray of the present embodiment is a groove-shaped structure including a bottom wall and a side wall 31 disposed around the circumference of the bottom wall. Wherein the bottom wall includes a bottom wall body 32 and a boss 34 that is provided to project upwardly relative to the bottom wall body 32. The bottom wall body 32 of the present embodiment is a plane perpendicular to the side wall 31.
The water distribution disk of the cooling tower in the embodiment is in a groove shape. Specifically, the length of the water distribution disk of the cooling tower is 2500mm, the width of the water distribution disk is 1200mm, and the depth of the water distribution disk is 150 mm.
A plurality of bosses 34 are uniformly disposed on the bottom wall. The boss 34 of the present embodiment is a hemispherical shell. The radius of the hemispherical shell of the embodiment is required to be lower than the water level height when the cooling tower is at the maximum load, namely when the cooling tower runs at full load, the water level of the cooling water is required to cover all the hemispherical shells, and the cooling water does not overflow the water distribution plate.
In the embodiment, the radius of the hemispherical shell is 100 mm. The clearance between two adjacent protruding hemispherical shells is 100 mm. Under the numerical range, when the cooling tower of the embodiment runs at full load, the water level of the cooling water can cover all the hemispherical shells, and the cooling water does not overflow the water distribution plate.
The first water outlets 33 are uniformly arranged on the bottom wall body 32. The first water outlets 33 are uniformly arranged on the bottom wall body 32 of the water distribution tray, and the size of the first water outlets 33 is such that when the water distribution tray is at the minimum amount of cooling water, the cooling water can be distributed over all the first water outlets 33 on the bottom wall of the water distribution tray. For example, at a cooling water flow rate of one third of the full load, the first water outlets 33 of the water distribution tray of the cooling tower can be completely filled with cooling water and the water distribution is uniform.
Specifically, in this embodiment, the diameter of the first water outlet 33 is 5mm, and the distance between two adjacent first water outlets 33 is 50 mm.
The hemispherical shell of this embodiment has the second water outlets 35 uniformly arranged thereon. The second water outlets 35 on the hemispherical shell are approximately uniformly arranged on the whole hemispherical surface, and the density of the arrangement of the second water outlets 35 on the bottom wall body 32 and the size of the first water outlets 33 are approximately the same.
Specifically, the diameter of the second water outlet 35 is 5mm, and the height difference between the two second water outlets 35 is 10 mm.
At the time of full load cooling water flow, the cooling water in the water distribution tray of the cooling tower can flow over all the first water outlets 33 on the bottom wall 32 of the water distribution tray and all the second water outlets 35 on the hemispherical shell, and the water flow is ensured not to overflow the water distribution tray.
Between the minimum and full cooling water flows, the cooling water is distributed uniformly over the bottom wall 32 and the convex hemispherical shell portion.
The area of the boss 34 of the present embodiment is larger than that of the bottom wall body 32.
Specifically, the area of the bottom wall body 32 of the water distribution tray of the present embodiment is about 1/3 of the total area of the bottom wall. The total spherical area of the plurality of convex hemispherical shells is about 2/3 times the total area of the bottom wall.
As shown in fig. 2, a plurality of first water outlets 33 are disposed at a connection portion of the bottom wall body 32 and the convex hemispherical shell. The plurality of first water outlets 33 are circumferentially distributed along the edge of the hemispherical shell. Specifically, the interval between the adjacent first water outlets 33 is about 50 mm. The first water outlet 33 has a diameter of about 5 mm.
The water distribution plate of this embodiment adopts mould processing, one shot forming. The water distribution plate can be made of glass fiber reinforced plastic.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
