[0028] The tilt adjustment mechanism 43 is connected between the top of the folding frame mechanism 41 and the top of the frame module 1, and the tilt adjustment mechanism 43 is used to adjust the tilt angle of the folding frame mechanism 41; the tilt adjustment mechanism 43 specifically includes a worm gear 431, a worm 432 and a tilt drive assembly 433.

[0029] Implementation principle: When the fan module 3 is started, an air flow path of the air inlet area 11-accommodation space 13-air outlet area 12 can be formed, and the air takes away the heat of the heat exchange medium inside the heat exchange module 2 to reduce the temperature of the heat exchange medium. Since the air flow rate in the upper area of ​​the heat exchange module 2 is generally greater than the air flow rate in the lower area, that is, the air intake in the upper and lower areas of the heat exchange module 2 is uneven; at this time, the tilt drive assembly 433 drives the first cross bar 411 to rotate through the meshing transmission of the worm gear 431 and the worm 432, thereby driving the folding frame mechanism 41 to rotate as a whole, realizing the adjustment of the coverage angle of the folding frame mechanism 41, and then, the folding drive motor 4141 drives the corresponding two sets of movable seats 82 to move through the bidirectional screw 4142 to change the shape of the scissors assembly 413, so as to drive the first cross bar 411 and the second cross bar 412 to move closer to / away from each other, realizing the folding / unfolding of the folding frame mechanism 41 as a whole, realizing the coverage area of ​​the folding frame mechanism 41. Volume adjustment, during this process, the winding drive component 423 drives the winding shaft 421 to wind up / unwind the partition cloth 422, and the winding / unwinding action depends on the folding / unfolding of the folding frame mechanism 41 as a whole, so that the partition cloth 422 is always kept in the unfolded state on the windward side of the scissors component 413, realizing the partition function of the folding partition mechanism 42; on this basis, the coverage area and coverage angle of the guide module 4 between the air inlet area 11 and the air outlet area 12 of the partition can be adjusted according to actual needs, so that the air flow in the upper area of ​​the heat exchange module 2 is blocked, and more air is converted to pass through the lower area of ​​the heat exchange module 2, so that the air can pass through the upper and lower areas of the heat exchange module 2 more evenly to improve the overall heat exchange efficiency of the heat exchange module 2.

[0030] In the above description, the actual demand for coverage area and coverage angle is determined by electronic control. Specifically, multiple groups of wind speed sensors 6 are provided within the accommodating space 13. The multiple groups of wind speed sensors 6 are fixedly arranged on the heat exchange module 2 at intervals from top to bottom. The frame module 1 is fixedly provided with a controller 7.

The wind speed sensors 6 and the controller 7, the controller 7 and the folding drive assembly 414, the controller 7 and the winding drive assembly 423, and the controller 7 and the tilting drive assembly 433 are all electrically connected via preset wires. The wind speed signals of the corresponding areas are fed back to the controller 7 by the multiple groups of wind speed sensors 6. The controller 7 then makes an evaluation and drives the folding drive assembly 414, the winding drive assembly 423, and the tilting drive assembly 433 to perform corresponding actions, thereby adjusting the coverage area and coverage angle of the diversion module 4 according to actual needs.
