Embodiment 1
[0090] Embodiment one, such as figure 1 Shown: a cooling type electrical cabinet, a hollow partition 1 is arranged inside the cabinet, and the interior of the hollow partition 1 is divided into four areas 1-1, 1-2, 1-3, 1-4;
[0091] The four areas 1-1, 1-2, 1-3, 1-4 are arranged in multiple U-shaped channels;
[0092] The U-shaped passages in the four regions 1-1, 1-2, 1-3, 1-4 are passed with a cooling medium, preferably, the cooling medium is air below 0°.
[0093] like figure 2 As shown, the middle part of the bottom of the hollow partition 1 is provided with a first through hole 1-5, the first through hole 1-5 is used for air intake, and the four areas 1-1, 1-2, 1-3, 1- 4 are interconnected, the first area 1-1, the second area 1-2 are mutually symmetrical, the third area 1-3, and the fourth area 1-4 are mutually symmetrical;
[0094] The air intake ducts at the connecting parts of the first area 1-1, the second area 1-2, the third area 1-3, and the fourth area 1-4 are...
Embodiment 2
[0100] In the second embodiment, a second through hole 1-6 corresponding to the first through hole 1-5 is provided on the top surface of the hollow partition 1, and a first tube 1-6 is extended above the second through hole 1-6. 7;
[0101] A second pipe 5-1 is rotatably connected above the first pipe 1-7, and four horizontal bend pipes 5-2 are arranged around the second pipe 5-1, the purpose of which is to utilize the reaction of wind force The force makes the second pipe 5-1 rotate; four inclined air pipes 5-3 are evenly distributed around the second pipe 5-1; the inclined air pipe 5-3 includes: a first inclined part 5-3 -1, the second vertical part 5-3-2.
[0102] The second pipe 5-1, the inclined air pipe 5-3 and the bent pipe 5-2 form the self-rotating air pipe.
[0103] Ventilation holes are arranged on the top of the cabinet.
[0104] The second embodiment further improves the cooling effect and cooling speed on the basis of the first embodiment; on the one hand, the p...
Embodiment 3
[0106] Embodiment 3, Embodiment 1, and Embodiment 2 are equivalent to combining the two heat dissipation methods introduced in the background art. However, the two methods have their respective applicable conditions.
[0107] The purpose of Embodiment 3 is to add a function: the schemes of Embodiment 1 and Embodiment 2 can be freely selected, that is, the following three modes are available: 1) low-temperature cooling air through the horizontal partition; 2) low-temperature cooling through the horizontal partition Air + air blowing from the upper part of the partition; 3) The upper part of the partition is upward.
[0108] The horizontal hollow partition 1 adopts such as Figure 8 In the arrangement shown, a third pipe 1-8 is arranged at the bottom of the horizontal partition 1, said third pipe 1-8 vertically corresponding to the first pipe 1-7.
[0109] The first area 1-1 and the second area 1-2 of the partition area are symmetrical to each other, the third area 1-3 and the...
