In this embodiment, by arranging the inclined plate 721 at the through hole 711, the fan is prevented from swinging to spray water drops into the air duct, and even if water drops are thrown into the air duct, the water drops can flow back to the fan cavity 3 through the inclined plate 721 under the action of gravity, so that the influence of the water spraying and the like on various electric components in the press cavity 4 is reduced.

The air guiding portion 72 further includes two connection plates 722, the two connection plates 722 are respectively connected to two sides of the inclined plate 721 opposite to each other, the two connection plates 722 are connected with the inclined plate 721 to define the air outlet channel 74, the air outlet channel 74 is communicated with the air inlet channel 73 through a through hole 711, and air flow in the air inlet channel 73 conveniently enters the air outlet channel 74 through the through hole 711, so that air guiding effect on the air flow is achieved. An air outlet 76 is formed between the end of the air guiding portion 72 and the bottom wall of the cover 71, and the air outlet 76 is arranged away from the outdoor fan 31, so that water drops thrown by the outdoor fan 31 are prevented from entering the air channel through the air outlet 76.

In the present embodiment, the connection plate 722 is formed by extending downward from the second side wall of the through hole 711 along the vertical direction, and the connection plate 722 extends downward to be connected with the inclined plate 721, where the second side wall is disposed adjacent to the first side wall, and the arrangement makes the air guiding portion 72 integrally connected with the cover 71, which is simple in structure and convenient to manufacture.

Further, in the above embodiment, the water baffle 8 is disposed on the third side wall of the through hole 711, the water baffle 8 extends from the third side wall to connect with the two connection plates 722 along the direction away from the partition plate 2, and the water baffle 8 extends to the inner side of the connection plate 722, and the third side wall is disposed opposite to the first side wall.

In the above embodiment, the air outlet 76 is formed between the end portions (the free ends of the connection plates 722 and the free ends of the inclined plates 721) of the air guide 72 and the bottom wall of the cover 71, and the connection plates 722 are formed by extending the second side wall downward in the vertical direction, so that the air outlet 76 is formed between the end portions of the air guide 72 and the third side wall of the through-hole 711 near the air inlet 75. By providing the water deflector 8 extending to the inner side of the connection plate 722, rainwater can be further stopped at the air outlet 76, and the rainwater will flow back down the inclined plate 721 to the fan chamber 3, thereby avoiding the rain water entering the air duct along with the rotation of the outdoor fan 31.

Referring to fig. 11, on a projection in the vertical direction, a distance between the free end of the water deflector 8 and the free end of the connection plate 722 is dimensioned as d1, wherein d1 is 5mm. This arrangement makes the connection size of the water deflector 8 and the connection plate 722 smaller, avoiding affecting the ventilation effect of the air duct.

The positional relationship between the air outlet 76 of the air duct and the outdoor fan 31 directly affects the air speed in the air duct, thereby affecting the heat dissipation effect of the electronic control box 5. When the outdoor fan 31 rotates anticlockwise, the wind speed at the edge position of the outdoor fan 31 is maximum, the pressure at the corresponding edge position is minimum, and when other factors are unchanged, the wind speed generated by the pressure difference is maximum. When the sectional area of the air outlet 76 is fixed, the larger the wind speed passing through the section, the more heat is taken away in unit time, and the better the heat dissipation effect is. Therefore, in the present disclosure, the air outlet 76 is disposed near the edge of the outdoor fan 31, and the negative pressure generated by the edge of the outdoor fan 31 is used to take away more heat on the radiator 54, so as to improve the heat dissipation effect.

Specifically, referring to fig. 13 and 14, in the present embodiment, the distance between the bottom wall of the air outlet duct 74 and the edge of the outdoor fan 31 is d2 on the first axis, where the first axis is the direction of the vertical line from the axis of the outdoor fan 31 to the bottom wall of the air outlet duct 74. In this embodiment, d2 is 20mm, and this arrangement makes the air outlet 76 closer to the outdoor fan 31, and the negative pressure at the air outlet 76 is low, so that the wind speed in the air duct is improved, and the heat dissipation efficiency is further improved. As shown in fig. 5, the direction of F2 is the direction of the first axis.

Further, in order to facilitate the stable placement of the wind scooper 7 on the partition plate 2, a flange 9 is provided at the opening 21 of the partition plate 2, a limiting part 77 is provided outside the wind scooper 7, and during installation, the bottom surface of the wind scooper 7 is lapped on the top surface of the flange 9 and the lap joint part is attached to the partition plate 2. In this embodiment, the opening 21 of the partition plate 2 is U-shaped, and the lap joint part is a limit rib arranged outside the wind scooper 7.

This setting makes wind scooper 7 carry out the positioning action in the installation, and turn-ups 9 form the overlap joint portion of baffle 2, form overlap joint groove 78 between the bottom surface of overlap joint portion and wind scooper 7, during the installation, can offset wind scooper 7's bottom surface and turn-ups 9 earlier for overlap joint portion is connected with overlap joint groove 78, carries out subsequent welding or screw connection again, and turn-ups 9 have the effect of location, have solved the problem of location difficulty when installing the wind channel, have convenient operation's advantage.

Referring to fig. 11, at least one reinforcing rib 91 connected to the flange 9 is provided on the partition plate 2, so that the structural strength of the flange 9 is improved. In this embodiment, the reinforcing rib 91 is triangular, and is connected between the partition board 2 and the flange 9.
