Description

A cooling device for cooling towers

technical field

The utility model relates to a heat dissipation device for a cooling tower, and is particularly suitable for being installed in a sprinkler tray of a cooling tower for heat dissipation.

Background technique

There is no heat dissipation device in the sprinkler pan of the traditional cooling tower. The hot water discharged from the air conditioner is passed through the pipeline into the sprinkler pan of the cooling tower, and then distributed by the sprinkler pan and falls into the packing sheet layer for cooling and heat dissipation. During this process, the hot water basically does not have any opportunity to dissipate heat in the sprinkler pan, so the temperature of the hot water directly falling into the packing layer is relatively high, so that the heat dissipation efficiency of the cooling tower cannot be further improved.

Contents of the invention

The purpose of the utility model is to provide a heat dissipation device suitable for the sprinkler tray of a cooling tower, which can perform preliminary heat dissipation on the hot water entering the sprinkler tray, so as to improve the heat dissipation efficiency of the cooling tower.

The technical solution adopted by the utility model: a heat dissipation device for a cooling tower, including an impeller driven by water flow, and heat dissipation fans installed on both sides of the impeller, and the heat dissipation fan is connected with the impeller through a linkage mechanism.

At least one heat dissipation fan is respectively installed on both sides of the impeller.

A heat dissipation fan is respectively installed on both sides of the impeller, and the heat dissipation fan is coaxially linked with the impeller.

Two heat dissipation fans are respectively installed on both sides of the impeller, and driving gears are installed on both sides of the central axis of the impeller, and the driving gear drives the heat dissipation fan through the driven gear. The driven gear meshes with the driving gear. The cooling fan is coaxially linked with the driven gear.

The heat dissipation device is installed in the sprinkler pan of the cooling tower.

The utility model has the following salient features:

(1) The impeller of the cooling device is driven by the water flow output from the water inlet pipe, and then drives the cooling fans on both sides to rotate, so as to speed up the air circulation in the sprinkler pan and make the hot water in it dissipate heat initially. The temperature of the hot water in the filler sheet layer is relatively low, which is convenient for further improving the heat dissipation efficiency of the cooling tower.

(2) During the rotation of the impeller of the cooling device, the water flow output from the water inlet pipe is scattered (in the shape of water droplets), so that the contact area between the hot water and the flowing air is increased, which is convenient for heat dissipation and cooling.

(3) During the rotation of the impeller of the cooling device, the effect of slowing down the water flow speed can be achieved, so that the water flow output from the water inlet pipe can fall into the sprinkler pan slowly and steadily, avoiding the strong fluctuation of the water flow in the sprinkler pan, which is beneficial The sprinkler pan distributes hot water more evenly across the fill sheets.

(4) The kinetic energy of the water flow is used to drive the impeller to rotate, and then to drive the fan to rotate, so that the kinetic energy can be recycled without any cost.

(5) The number of fans of the utility model depends on the size of the cooling tower, and the larger the cooling tower with water output, the number of fans will increase accordingly.

As shown in Figure 1, the heat dissipation device of the cooling tower in this embodiment includes an impeller 1 driven by water flow, and a heat dissipation fan 2 is respectively installed on both sides of the impeller 1, and the heat dissipation fan 2 is coaxially linked with the impeller 1 . The above-mentioned cooling device is installed in the sprinkler pan 3 of the cooling tower, and is fixed on the bottom of the sprinkler pan 3 through the installation frame, and the impeller 1 is placed at the water outlet of the water inlet pipe 4 . When the cooling tower is working, the water flow output by the water inlet pipe 4 can drive the impeller 1 to rotate, and the central shaft 13 of the impeller 1 then drives the cooling fans 2 on both sides to rotate, so as to speed up the air circulation in the sprinkler plate 3 and make the heat therein The water initially dissipates heat. As shown in the figure, during the rotation process of the impeller 1, the water flow output by the water inlet pipe 4 is broken up into a drop shape, so that the contact area between the hot water and the flowing air is increased, which is convenient for heat dissipation and cooling. In addition, during the rotation of the impeller 1, it can also slow down the water flow speed, so that the water flow output by the water inlet pipe 4 falls into the sprinkler pan 3 slowly and steadily, so as to avoid the strong fluctuation of the water flow in the sprinkler pan, which is conducive to sprinkling water. The pan distributes hot water more evenly across the fill sheets.

Embodiment two:

When the cooling tower is working, the water flow output by the water inlet pipe 4 can drive the impeller 1 to rotate, and the central axis of the impeller 1 drives the driving gear 11 on both sides to rotate, and the driving gear 11 drives the driven gear 12 to rotate, and the cooling fan 2 follows The moving gear 12 rotates together. Since the radius of the driving gear 11 is larger than that of the driven gear 12, the heat dissipation fan 2 (linked with the driven gear 12) can be driven to rotate rapidly by using the gear transmission principle, further accelerating the air circulation in the sprinkler tray 3, so that the The hot water initially dissipates heat. As shown in the figure, during the rotation process of the impeller 1, the water flow output by the water inlet pipe 4 is broken up into a drop shape, so that the contact area between the hot water and the flowing air is increased, which is convenient for heat dissipation and cooling. In addition, during the rotation of the impeller 1, it can also slow down the water flow speed, so that the water flow output by the water inlet pipe 4 falls into the sprinkler pan 3 slowly and steadily, so as to avoid the strong fluctuation of the water flow in the sprinkler pan, which is conducive to sprinkling water.
