However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides an indirect cooling tower cooling device, including a triangular frame unit 100, including a triangular frame 101 arranged in a triangle, the bottom edge of the triangular frame 101 being connected by a cooling fan frame 102, and the triangular frame 101 and the cooling fan frame 102 forming a triangular frame.

[0032] The condensation circulation unit 200 includes a vertically arranged evaporation section 201, a condensation section 202 connected to the evaporation section 201, and a reflux section 203 connected to the condensation section 202;

[0033] The valve opening and closing unit 300 includes an opening and closing valve 301 that cooperates with the evaporation section 201, and an opening and closing assembly 302 that cooperates with the opening and closing valve 301.

[0034] Furthermore, the triangular frame 101 includes a first vertical frame 101a and a second vertical frame 101b arranged vertically. The first vertical frame 101a has two members, which together with the second vertical frame 101b form an isosceles triangle with a vertex angle of fifty degrees. A horizontal frame 101c is equidistantly connected between the first vertical frame 101a and the second vertical frame 101b. The first vertical frame 101a, the second vertical frame 101b, and the horizontal frame 101c together form a cooling unit, and multiple cooling units together form a cooling triangle.

[0035] Furthermore, the evaporation section 201 includes a vertical main evaporation pipe 201a and a horizontal branch evaporation pipe 201b. The horizontal branch evaporation pipe 201b is located at the lower end of each cooling unit and is connected to the vertical main evaporation pipe 201a to uniformly distribute the hot steam. Multiple condensation sections 202 are connected to the upper end of the horizontal branch evaporation pipe 201b.

[0036] Furthermore, the condensing section 202 is an inverted U-shaped pipe, with one end connected to the evaporating section 201 and the other end connected to the reflux section 203. Multiple heat dissipation plates 202a are evenly and equidistantly arranged on its outer side. The condensing section 202 is fully covered with cooling units for condensing and dissipating heat from the hot steam.

[0037] Furthermore, the on / off valve 301 is rotatably disposed inside the lower end of the condensing section 202, and a rotating rod 301a is provided at one end of the valve that extends out of the condensing section 202, which can adjust the opening and closing state of the condensing section 202.

[0038] Furthermore, the opening and closing assembly 302 includes a slide rail 302a disposed between the first longitudinal frame 101a and the second longitudinal frame 101b. An opening and closing plate 302b is disposed on the slide rail 302a, which can slide back and forth along the slide rail 302a to adjust the opening and closing valve 301. The end of the opening and closing plate 302b extending out of the second longitudinal frame 101b is also provided with a telescopic plate 302c and an opening and closing drive component 302d.

[0039] Furthermore, the opening / closing plate 302b cooperates with the rotating rod 301a, and is provided with a first opening / closing groove 302b-1, a second opening / closing groove 302b-2, a third opening / closing groove 302b-3, and a fourth opening / closing groove 302b-4 spaced apart. The first opening / closing groove 302b-1 consists of a vertical groove and three times the length of a horizontal groove; the second opening / closing groove 302b-2 consists of a single horizontal groove, a vertical groove, and two times the length of a horizontal groove; the third opening / closing groove 302b-3 consists of two times the length of a horizontal groove, a vertical groove, and a single horizontal groove; and the fourth opening / closing groove 302b-4 consists of three times the length of a horizontal groove and a vertical groove. Based on actual needs, more slots can be set on the opening and closing plate 302b to achieve more precise control of the condensation section 202. The first opening and closing slot 302b-1, the second opening and closing slot 302b-2, the third opening and closing slot 302b-3 and the fourth opening and closing slot 302b-4 are all matched with the rotating rod 301a and are equidistant along the length of the opening and closing plate 302b. A connecting shaft 302b-5 is also provided at the end of the opening and closing plate 302b. The telescopic plate 302c is symmetrically provided with connecting slots 302c-1 on the left and right, which are matched with the connecting shaft 302b-5.

[0040] In use, the device is turned on to dissipate heat. When excessive heat dissipation occurs due to external temperature or other reasons, the opening and closing drive 302d is activated, pushing the telescopic plate 302c forward. Under the action of the connecting groove 302c-1, the opening and closing plate 302b slides accordingly. At this time, the vertical groove of the first opening and closing groove 302b-1 drives the rotating rod 301a to rotate. After the opening and closing plate 302b slides forward by a distance equal to one horizontal groove, the opening and closing valve 301, which cooperates with the first opening and closing groove 302b-1, is completely closed, and the heat dissipation area is reduced accordingly. If the temperature continues to drop, the opening and closing drive 302d is activated again, causing the opening and closing plate 302b to slide forward again by a distance equal to one horizontal groove. This time, the opening and closing valve 301, which cooperates with the second opening and closing groove 302b-2, is completely closed. Therefore, the heat dissipation area can be adjusted accordingly by adjusting the opening and closing plate 302b based on external conditions such as temperature.

[0041] In summary, by using the valve opening and closing unit 300 to uniformly adjust the heat dissipation area of ​​the device, the heat dissipation efficiency of the device is kept at a level that meets the working requirements of the upstream and downstream equipment, thus avoiding excessive heat dissipation that could lead to icing.

[0042] Example 2

[0043] Reference Figures 1-5 This is the second embodiment of the present invention. Based on the previous embodiment, this embodiment provides an indirect cooling tower cooling device, which further includes: a cooling adjustment unit 400, including a cooling fan 401 rotatably disposed on a cooling fan frame 102, and an adjustment component 402 cooperating with the cooling fan 401. The adjustment component 402 also cooperates with the opening and closing component 302.

[0044] Furthermore, multiple cooling fans 401 are equidistantly arranged along the cooling fan frame 102, and an adjustment rod 401a is connected to one side of each fan to adjust the opening degree of the cooling fan 401.

[0045] Furthermore, the adjustment assembly 402 includes an adjustment slider 402a that is vertically slidably disposed on the cooling fan frame 102, an adjustment sleeve 402b that is connected and cooperates with the adjustment slider 402a, and an adjustment drive member 402c that cooperates with the adjustment sleeve 402b.

[0046] Furthermore, multiple adjustment slots 402a-1 are evenly spaced on the adjusting slider 402a. The adjustment slots 402a-1 are transverse grooves. The adjusting rod 401a cooperates with the adjustment slots 402a-1. Depending on the height of the adjustment slots 402a-1, the adjusting rod 401a can change the opening degree of the cooling fan 401 accordingly. One of the opening and closing plates 302b has a follower slot 302b-6 at its end. The width of the follower slot is the same as the diameter of the adjusting sleeve 402b. A follower rod 402a-2 extends out from the rear side of the adjusting slider 402a. The follower rod 402a-2 cooperates with the adjusting sleeve 402b. The adjusting sleeve 402b can slide and extend along the follower rod 402a-2. The adjusting sleeve 402b cooperates with the follower slot 302b-6.

[0047] There are two modes available for use. Mode 1: When the external wind force is relatively stable, extend the adjusting sleeve 402b to engage with the follower groove 302b-6. In this mode, the opening and closing plate 302b slides back and forth to adjust the opening and closing of the opening and closing valve 301. At the same time, the follower groove 302b-6 at the rear end of the opening and closing plate 302b will drive the adjusting sleeve 402b to move up and down. The adjusting sleeve 402b drives the adjusting slider 402a to move up and down, thereby realizing that the opening degree of the cooling fan 401 changes in accordance with the change of the condensation area. Mode 2: When the external wind force is relatively turbulent, retract the adjusting sleeve 402b to disengage it from the follower groove 302b-6. In this mode, activate the adjusting drive component 402c. According to the device's wind force requirements, push the adjusting slider 402a up and down to adjust the opening degree of the cooling fan 401 to adapt to the device's heat dissipation requirements.

[0048] In summary, the cooling adjustment unit 400 can adjust the opening and closing angle of the cooling fan 401 in accordance with the valve opening and closing unit 300 to adapt it to the cooling needs of the device. It can also adjust the opening and closing angle of the cooling fan 401 independently to meet the wind force requirements of different parts on the windward and leeward sides or under turbulent external wind conditions.
