For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Example 1

[0022] like Figure 1 and Figure 2 As shown, the adjustable top air inlet cooling device described in this embodiment includes an air inlet chamber 1 and two heat exchange chambers 2 arranged on the left and right sides of the air inlet chamber 1. The air inlet chamber 1 is open on the upper side and an induced draft fan is arranged on the inner side near the opening, which is responsible for guiding the air flow upward out of the air inlet chamber 1. The heat exchange chamber 2 is connected to the air inlet chamber 1 and the heat exchange chamber 2 has a top air inlet 3 and a side air inlet 4. The top air inlet 3 is cooperated with a closed mechanism with an angle adjustment. The closed mechanism is a movable shutter 5. The user can adjust the angle of the movable shutter 5 as needed to control the air inlet volume of the top air inlet 3; a spray pipe 6 and a heat exchanger 7 are arranged in the heat exchange chamber 2, and the spray pipe 6 is located above the heat exchanger 7. The circulating water to be cooled is sprayed down from the spray pipe 6 and falls after passing through the heat exchanger 7. Preferably, a water receiving pool 8 is arranged below the heat exchange chamber 2, and the water flow cooled by the heat exchanger 7 falls into the water receiving pool 8 and is then sent out uniformly;

[0023] The heat exchanger 7 includes a plurality of staggered first channels 9 and second channels 10. Specifically, the heat exchanger 7 includes a plurality of mutually parallel heat exchange fins 11. The first channel 9 or the second channel 10 is formed between adjacent heat exchange fins 11. The first channel 9 is completely or partially closed on the side facing the side air inlet 4 to achieve the purpose of reducing or preventing the air flow from entering the first channel 9, thereby restricting the direct contact heat exchange process between air and water. The specific closing form is to provide a convex and a groove on one side of the heat exchange fin 11. When the convex and the groove are continuous, the heat exchange fin 11 is closed. And when it is at the same height as the heat exchange plate 11, the cooperation of the protrusion and the slot will completely close the side of the first channel 9 facing the side air inlet 4; when the protrusion and the slot are arranged in multiple groups corresponding to each other in the vertical direction and there is a gap between the protrusions and the slots of adjacent groups, the cooperation of the protrusion and the slot can partially close the side of the first channel 9 facing the side air inlet 4; the top surface, bottom surface and side facing the air inlet chamber 1 of the first channel 9 are open; the top surface of the second channel 10 is closed, and the bottom surface of the second channel 10 and the side facing the air inlet chamber 1 and the side air inlet 4 are open.

[0024] The working principle of this embodiment is:

[0025] In summer mode, the movable shutter 5 is opened at a certain angle, and the induced draft fan is running, and the outside air enters the heat exchange chamber 2 from the side air inlet 4 and the top air inlet 3 at the same time. The airflow entering from the side air inlet 4 can penetrate into the second channel 10 horizontally, and the airflow entering from the top air inlet 3 can penetrate into the first channel 9 vertically. Direct air-water contact heat exchange occurs in the first channel 9. No water enters the second channel 10 because the top surface is closed. Therefore, the airflow in the second channel 10 and the air-water in the first channel 9 undergo inter-wall heat exchange. This mode includes direct air-water contact heat exchange, with high heat exchange efficiency, which is conducive to completing the water cooling task;

[0026] In winter mode, the movable shutter 5 is closed and the induced draft fan is running, so that the outside air can only enter from the side air inlet 4 and penetrate into the second channel 10 laterally. Since the top surface of the second channel 10 is closed, no water enters. Therefore, the air flow in the second channel 10 and the water flow in the first channel 9 undergo inter-wall heat exchange without direct contact between air and water. Water cooling is achieved without generating a large amount of dripping loss and white smoke, which is conducive to the realization of environmental protection and water saving goals.

[0027] Example 2

[0028] like Figure 3As shown, the difference between this embodiment and embodiment one is that a water baffle 12 is provided on the top of the heat exchanger 7, and the spray water of the spray pipe 6 cannot pass over the water baffle 12. The water baffle 12 is perpendicular to the first channel 9 and the second channel 10. The application of the water baffle 12 increases the space for the air-water non-direct contact heat exchange process to occur, and compresses the space for the air-water direct contact heat exchange process to occur, so that the water-saving effect is better in both winter mode and summer mode, and is suitable for use in scenarios with small circulating water cooling load. The other parts of this embodiment are the same as embodiment one and will not be repeated here.

[0029] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
