The annular water receiving trough is located below the baffle and opposite the edge of the baffle and the lower end of the outer surface of the finned heat exchanger. The upper end of the inner wall of the annular water receiving trough and the baffle form an annular negative air outlet. The air compressor pump is located inside the device chamber and is connected to the inner cavity of the annular water receiving trough through the air guide pipe. The annular air outlet blows air towards the bottom of the annular water receiving trough, and the air from the annular negative air outlet blows air towards the top of the annular water receiving trough. Water vapor is sprayed out from the lower part of the air inlet window.

[0009] The outdoor unit for physically removing water ice is characterized in that: the casing is square, and the device cavity and heat exchange cavity are square;

[0010] The annular water receiving trough is square-shaped.

[0011] This utility model discloses an outdoor unit for physically removing water and ice. The arrangement of an annular water receiving tank and an air compressor pump, along with the combined action of the air from the annular negative vent and the annular air outlet, throws water, ice, and impurities from the annular water receiving tank into the outdoor air through the air inlet window.

[0015] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1 As shown, an outdoor unit for physically removing water ice includes a casing 1, an exhaust fan 2, a finned heat exchanger 3, a baffle 4, an air compressor pump 5, an air duct 6, and an annular water receiving tank 7.

[0018] The housing 1 includes a device cavity 11, a heat exchange cavity 12, and an air outlet 13, which are arranged sequentially from top to bottom; the heat exchange cavity 12 is provided with an air inlet window 121; the device cavity 11 is used to house the compressor, the liquid storage tank, and the gas-liquid separator.

[0019] Finned heat exchanger 3 is annular;

[0020] The annular water receiving trough 7 is hollow, with its inner sidewall extending upward to form a baffle 71 and having a downward-facing annular air outlet 72.

[0021] The finned heat exchanger 3 is located inside the heat exchange chamber 12 and is opposite to the air inlet window 121. The baffle 4 is located at the bottom of the finned heat exchanger 3 and is fixed. When the baffle is set and the exhaust fan 2 is working, outdoor air enters the cavity formed by the finned heat exchanger 3 through the finned heat exchanger 3 and is finally discharged from the exhaust port 13 by the exhaust fan 2. The annular water receiving trough 7 is located below the baffle 4 and is opposite to the edge of the baffle 4 and the lower end of the outer surface of the finned heat exchanger 3. The upper end of the baffle 72 of the annular water receiving trough 7 and the baffle 4 form an annular negative air outlet 8. The air compressor pump 5 is located inside the device cavity 11 and is connected to the inner cavity of the annular water receiving trough 7 through the air guide pipe 6. The annular air outlet 72 blows the air towards the bottom of the annular water receiving trough 7, and the air from the annular negative air outlet 8 blows towards the top of the groove of the annular water receiving trough 7. Water vapor is sprayed out from the lower part of the air inlet window 121.

[0022] With this structure, the air compressor pump and the compressor work simultaneously when heating, which effectively prevents water from accumulating or freezing in the annular water receiving tank 7, and can also effectively remove debris.

[0023] The housing 1 is square, and the device cavity 11 and the heat exchange cavity 12 are square.

[0024] The annular water receiving trough 7 is square-shaped.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
