[0048] Specifically, the heat exchange part 2 includes a sealed shell 21, and expansion plates 22 are arranged on both sides of the interior of the sealed shell 21. Several expansion plates 22 are staggered stacked structures. The expansion plates 22 are at least used to increase the contact time between the water inside the upper cover 3 and the rising air when the water falls.

[0049] In this embodiment, both sides of the heat exchange part 2 are provided with inlet and outlet liquid pipes 9, and the inlet and outlet liquid pipes 9 are two interfaces, one interface is connected to the water pipe that needs cooling medium, and the other interface is connected to the water pipe of the cooling medium that has been cooled down, so that the cooling medium circulates inside the heat exchange part 2. The inlet and outlet liquid pipes 9 are connected to the coil 91 located above the heat exchange part 2, and the cooling medium circulates inside the coil 91 through the inlet and outlet liquid pipes 9;

[0050] In this embodiment, an upper cover 3 is provided on the top of the heat exchange part 2, and fans 8 are provided on both sides of the top of the upper cover 3. The fans 8 are at least used to draw air from bottom to top to make the air flow in a directional manner;

[0051] In this embodiment, independent water circulation components 7 are provided on both sides of the water tank 1, the heat exchange part 2 and the upper cover 3. The water circulation components 7 are at least used to circulate and pump the water inside the water tank 1 to the inside of the upper cover 3;

[0052] The water circulation assembly 7 includes a pump seat 71 installed on the outer wall of the water tank 1, and a water pump 72 is arranged on the outer wall of the top of the pump seat 71, and an upper water pipe 73 is connected to the water pump 72. The top of the upper water pipe 73 is provided with a spray pipe located inside the upper cover 3, and a plurality of spray heads 74 are arranged at the bottom of the spray pipe;

[0053] By starting the water pump 72, the cooling water in the water tank 1 can be pumped into the spray pipe through the upper water pipe 73, and then evenly sprayed downward by the spray head 74 below the spray pipe.

[0054] In the present embodiment, a plurality of connecting ear seats 14 are arranged between the water tank 1 and the heat exchange part 2, and between the heat exchange part 2 and the upper cover 3, and sealing rings are arranged between the water tank 1 and the heat exchange part 2, and between the heat exchange part 2 and the upper cover 3, thereby improving the connection strength and sealing between the water tank 1 and the heat exchange part 2, and between the heat exchange part 2 and the upper cover 3, ensuring that the space inside the water tank 1, the heat exchange part 2 and the upper cover 3 is isolated from the outside, thereby achieving a closed cooling effect.

[0055] In this embodiment, a partition 23 fixed on the inner wall of the sealed shell 21 is provided in the middle of the water tank 1, the heat exchange part 2 and the upper cover 3. The partition 23 divides the water tank 1, the heat exchange part 2 and the upper cover 3 into two independent cooling cavities.

[0056] Working principle: (1) The medium to be cooled is connected to the inlet and outlet liquid pipes 9, and the cooling medium is allowed to circulate in the inlet and outlet liquid pipes 9;

[0057] (2) Start the water circulation assembly 7 so that the cooling water in the water tank 1 is pumped to the interior of the upper cover 3 through the water circulation assembly 7, and the cooling water enters the spray head 74, allowing the cooling water to fall freely from top to bottom;

[0058] (3) The falling cooling water falls on the coil 91 inside the heat exchange part 2, realizing the cooling exchange and achieving the cooling effect on the medium;

[0059] (4) The cooling water continues to fall inside the heat exchange unit 2, and the heated cooling water is dispersed and falls on the expansion plate 22;

[0060] (5) If the cooling effect needs to be increased, the fan 8 can be started so that air enters through the air inlet 4 and circulates from bottom to top inside the water tank 1, the heat exchange part 2 and the upper cover 3. When the air circulates, it exchanges heat with the cooling water inside the expansion board 22, lowers the temperature of the cooling water, and collects the cooling water inside the water tank 1 again;

[0061] (6) By circulating in the above manner, a circulating cooling effect of the cooling medium is achieved. At the same time, the interior of the water tank 1, the heat exchange part 2 and the upper cover 3 are two independent cavities, and one of them can be used according to the cooling needs, thereby improving the utilization rate and high performance of the cooling tower.

[0062] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
