When the blower 5 is started and a hose 66 is cooperated, cold air can be blown to the power box 2 to cool it down; a moving mechanism 6 for improving the cooling effect is arranged on the L-plate 4; by arranging the moving mechanism 6, the cold air discharged from the hose 66 can be evenly diffused on the power box 2, so that the power box 2 can be evenly cooled; a spoiler mechanism 7 for improving the cooling range is arranged on the moving mechanism 6; by arranging the spoiler mechanism 7, the coverage area of ​​the cold air can be increased, thereby further improving the heat dissipation effect of the power box 2.

[0027] The above-mentioned moving mechanism 6 includes a rotating rod 61, a slide plate 62, a toothed disc 63, an impeller 64, a gear 65, a hose 66, a limiting groove 67, a limiting rod 68, and an air pipe 69; one end of the rotating rod 61 is rotatably connected to the side wall of the L plate 4, the other end of the rotating rod 61 is fixedly installed with an impeller 64, the outer wall of the rotating rod 61 is fixedly installed with a gear 65, the inner wall of the blower 5 is fixedly installed with an air pipe 69, and the air pipe 69 runs through the blower 5, and the end of the air pipe 69 away from the blower 5 is located obliquely above the impeller 64, and part of the wind blown by the blower 5 to the inside of the hose 66 will be discharged outward through the air pipe 69, at this time, the wind discharged through the air pipe 69 will impact the impeller 64, so that the impeller 64 drives the rotating rod 61 to rotate, the slide plate 62 is slidably connected to the inner wall of the L plate 4, and the slide plate 62 runs through the L plate 4, the inner wall of the slide plate 62 is fixedly installed with a hose 66, and the end of the hose 66 away from the slide plate 62 The end is fixedly installed at the air outlet of the blower 5. When the slide plate 62 slides back and forth up and down on the inner wall of the L plate 4, it will drive the hose 66 to move back and forth synchronously. The cold air discharged by the hose 66 can be evenly blown on the power box 2 through the up and down reciprocating movement of the hose 66, so that the power box 2 can be evenly cooled. A limiting groove 67 is provided on the slide plate 62, and the toothed disc 63 is rotatably connected to the side wall of the L plate 4. The toothed disc 63 is meshed with the gear 65. When the rotating rod 61 rotates, the gear 65 can drive the toothed disc 63 to rotate. A limiting rod 68 is fixedly installed on the side wall of the toothed disc 63. When the toothed disc 63 rotates, it will drive the limiting rod 68 to rotate synchronously. The outer wall of the limiting rod 68 is attached to the inner wall of the limiting groove 67. When the limiting rod 68 rotates, it will fit the inner wall of the limiting groove 67 and move back and forth, and push and pull the slide plate 62 back and forth, so that the slide plate 62 slides back and forth on the inner wall of the L plate 4.

[0028] The above-mentioned spoiler mechanism 7 includes a swing rod 71, a spoiler 72, a rectangular groove 73, a rotating drum 74, a spiral groove 75, an eccentric rod 76, and an L rod 77; the middle position of the swing rod 71 is hinged on the inner wall of the slide plate 62, and the spoiler 72 is fixedly installed on the bottom of the swing rod 71.

An L-rod 77 is fixedly installed on the side wall of the L-plate 4. The outer wall of the L-rod 77 fits against the inner wall of the spiral groove 75. When the rotating drum 74 reciprocates up and down, the spiral groove 75 is squeezed by the L-rod 77, thereby causing the rotating drum 74 to rotate back and forth.

[0029] Working principle: Starting the blower 5 and cooperating with the hose 66 can blow cold air to the power box 2 to cool it down. At the same time, a part of the wind blown by the blower 5 to the inside of the hose 66 will be discharged outward through the air pipe 69. At this time, the wind discharged through the air pipe 69 will impact the impeller 64, causing the impeller 64 to drive the rotating rod 61 to rotate. While the rotating rod 61 rotates, the gear 65 can drive the toothed disc 63 to rotate. While the toothed disc 63 rotates, it will drive the limit rod 68 to rotate synchronously. While the limit rod 68 rotates, it will fit the inner wall of the limit groove 67 and move back and forth, and push and pull the slide plate 62 back and forth, so that the slide plate 62 slides back and forth up and down on the inner wall of the L plate 4. At the same time, the slide plate 62 will drive the hose 66 to move back and forth up and down. The reciprocating up and down movement of the hose 66 can make the cold air discharged by it blow evenly on the power box 2, so that the power box 2 can be evenly cooled, thereby improving the cooling effect on the power box 2.

[0030] When the slide plate 62 moves back and forth up and down on the inner wall of the L plate 4, it will drive the rotating drum 74 to move back and forth synchronously. When the rotating drum 74 moves back and forth, the spiral groove 75 will be squeezed by the L rod 77, thereby causing the rotating drum 74 to rotate back and forth. When the rotating drum 74 rotates, it will drive the eccentric rod 76 to move back and forth on the inner wall of the rectangular groove 73. At the same time, the eccentric rod 76 will push and pull the swing rod 71 back and forth, so that the swing rod 71 swings back and forth. When the swing rod 71 swings back and forth, it will also drive the spoiler 72 to swing back and forth synchronously. Through the reciprocating swing of the spoiler 72, the cold air blown by the hose 66 to the power box 2 can be guided to the two sides of the power box 2, so that the cold air blown by the hose 66 to the power box 2 can be diffused to the two sides of the power box 2, thereby increasing the coverage area of ​​the cold air, thereby further improving the heat dissipation effect of the power box 2, which is beneficial to the stable operation of the power box 2.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
