Under the condition that snowflakes float in the sky in winter, a part of the floating snowflakes enter the outer shell 1 from the air outlet 11, after the snowflakes enter the outer shell 1, a part of the snowflakes can float into the first heat dissipation structure (the first heat dissipation structure A21 or the first heat dissipation structure B22) on the first shell 2 along with the wind, certain resistance is generated to the flowing of the air flow by arranging the snow prevention baffle (the first snow prevention baffle 41 and the second snow prevention baffle 42) on the first heat dissipation structure, so that the air quantity blown into the first shell 2 from the first heat dissipation structure is reduced, the probability that the snowflakes float into the first shell 2 from the first heat dissipation structure and then float into the second shell 3 from the second heat dissipation structure 31 is reduced, and the phenomenon that a large amount of snowflakes enter the second shell 3 to be melted into water to cause short circuit of an electric control element to be damaged is avoided. After entering the cavity through the first heat dissipation structure a21 and the first heat dissipation structure B22, the snow flakes entering the outer shell 1 are trapped in the snow melting cavity due to the blocking effect of the first snow guard 41 and the second snow guard 42, and a small amount of snow flakes are melted by themselves at a relatively high temperature. Under the condition that a plurality of snowflakes exist in the cavity, when the outdoor unit works, the snowflakes in the cavity can be melted by the heat emitted by the electric reactor in the first shell 2 and the electric control element in the second shell 3.

The area of the circular micro hole (the third through hole a4111) is smaller than that of the first through hole a211 and the projection of the circular micro hole on the side plate on the left side of the first housing 2 completely falls in the area where the first through hole a211 is located, so that the difficulty of passing snowflakes through the first through hole a211 and the third through hole a4111 can be further increased. The strip-shaped hole in the horizontal direction (the third through hole B4211) is not overlapped with the strip-shaped hole in the vertical direction (the first through hole B221), so that the difficulty of passing snowflakes through the first through hole B221 and the third through hole B4211 is increased. In addition, the first heat dissipation structure a21 and the first heat dissipation structure B22 are respectively disposed on opposite sidewalls of the first housing 2, so that the airflow can flow from one of the first heat dissipation structure a21 and the first heat dissipation structure B22 through the other, thereby allowing part of the snow to drift toward the other of the first housing 2 after entering the first housing 2 from one of the first heat dissipation structure a21 and the first heat dissipation structure B22, and even drift out of the first housing 2 from the other, thereby preventing the snow entering from the first heat dissipation structure on the first housing 2 from directly drifting toward the second heat dissipation structure 31 and entering the second housing 3.

Moreover, the arrangement of the first heat dissipation structure and the third heat dissipation structure on the first housing 2 and the snow guard is not limited to the above form, and the areas of the snow guard corresponding to the third heat dissipation structure and the areas of the first housing 2 corresponding to the first heat dissipation structure may be arranged in other staggered distribution manners, for example, the first through hole B221 may be a horizontal strip-shaped hole, a horizontal triangle-shaped hole, or a vertical opposite-shaped hole, the third through hole B4211 may be a vertical strip-shaped hole, a vertical circular hole, or a vertical opposite-shaped hole, and a portion of the first through hole B221 coincides with a portion of the third through hole B4211.

In addition, the "first snow guard 41 is disposed on the inner side of the first housing 2, and the second snow guard 42 is disposed on the outer side of the first housing 2" is only a specific embodiment, and those skilled in the art can adjust the first snow guard as required to adapt to specific applications, for example, the first snow guard 41 and the second snow guard 42 are both disposed on the outer side of the first housing 2, so that the space in the first housing 2 can be increased, and heat dissipation is facilitated; of course, both the first snow guard 41 and the second snow guard 42 may be disposed inside the first housing 2, but this occupies a space inside the first housing 2 and has a certain influence on heat dissipation.

In an alternative embodiment, the number of snow guards is one, which are provided on the second housing 3 and correspond to the second heat dissipating structure 31, and the engagement of the snow guards with the second heat dissipating structure 31 reduces the probability that snow entering the first housing 2 will enter the second housing 3 from the second heat dissipating structure 31 and reach the electrical control element. Those skilled in the art can understand that the number of the snow-proof baffles can be multiple, and the snow-proof baffles are respectively arranged on the first shell 2 and the second shell 3 and respectively correspond to the first heat dissipation structure and the second heat dissipation structure 31, so that the difficulty of entering the snowflakes entering the outer shell 1 into the first shell 2 from the second heat dissipation structure is increased, the difficulty of entering the snowflakes entering the first shell 2 into the second shell 3 from the second heat dissipation structure 31 is also increased, and the probability of entering the snowflakes into the second shell 3 is further reduced. In the case where the number of the snow guard plates is one or more than three, the specific form, the relative positional relationship, and the like of the snow guard plates and the corresponding heat dissipation structures are applicable.

In an alternative embodiment, the snow guard may not form a cavity with the first housing 2, for example, the snow guard may be disposed only at a position opposite to the first heat dissipation structure and/or the second heat dissipation structure, and the snow guard may not have an opening structure thereon, so that the airflow passes through the first heat dissipation structure or the second heat dissipation structure, flows around the snow guard in a plane parallel to the snow guard to the edge of the snow guard, and then enters the first housing or the second housing, thereby changing the path of the airflow, increasing the difficulty of entering the snowflakes with the wind, and further reducing the probability of entering the snowflakes.

In the case where the snow guard is disposed at a position corresponding to the second heat dissipation structure 31 and the second heat dissipation structure 31 includes the plurality of second through holes 311, the sum of the areas of the plurality of third through holes is not less than the sum of the areas of the plurality of second through holes 311. Through the arrangement, the airflow circulation area of the heat dissipation structure is ensured, so that the heat dissipation effect inside the first shell 2 and the second shell 3 is ensured, and the normal work of the outdoor unit of the air conditioner is facilitated.

Preferably, as shown in fig. 3, the air inlet direction of the first through hole B221 is along the horizontal direction, and the air inlet direction of the third through hole B4211 is inclined from top to bottom. Through the arrangement, the snowflakes enter the cavity between the second snow-proof baffle 42 and the first shell 2 along with wind from the third through hole B4211 and cannot directly blow towards the first through hole B221, so that the difficulty of entering the first shell 2 from the first through hole B221 is further increased, and the probability that the snowflakes enter the second shell 3 and reach the electric control element is reduced. Those skilled in the art can understand that the air inlet direction of the first through hole B221 is along the horizontal direction, and the air inlet direction of the third through hole B4211 is inclined from top to bottom is only a specific embodiment, and those skilled in the art can adjust the air inlet direction as required to adapt to specific application occasions, for example, the air inlet direction of the first through hole B221 is inclined from top to bottom, the air inlet direction of the third through hole B4211 is along the horizontal direction, or the air inlet direction of the first through hole B221 and the air inlet direction of the third through hole B4211 are both inclined, but the inclined directions are different, or other suitable arrangement modes make the air inlet direction of the third through hole B4211 and the air inlet direction of the first through hole B221 different, and the like. It can be understood that the air inlet direction of the first through hole a211 and the air inlet direction of the third through hole a4111 may also be different. In addition, under the condition that the snow-proof baffle is arranged on the second shell 3 and corresponds to the second heat dissipation structure, the air inlet direction of the second heat dissipation structure and the air inlet direction of the third heat dissipation structure can be different.
