At above-mentioned a kind of non-maintaining aerial cooler, described cooling piece is 4, and adjacent sheathed successively stack is connected with collector pipe after the described cooling piece inlet parallel, is connected with collector pipe after the outlet parallel connection.
At above-mentioned a kind of non-maintaining aerial cooler, described cooling piece is 4, adjacent sheathed successively stack, and series connection successively before and after described cooling piece import and the outlet, first cooling piece import and the outlet of last cooling piece are connected with collector pipe respectively.
At above-mentioned a kind of non-maintaining aerial cooler, described supporting bracket is arranged between the adjacent cooling piece.
At above-mentioned a kind of non-maintaining aerial cooler, described supporting bracket is arranged between the adjacent cooling piece.
At above-mentioned a kind of non-maintaining aerial cooler, described mounting panel is provided with and is used for and the fixing installing hole of electric motor end cap.
At above-mentioned a kind of non-maintaining aerial cooler, described mounting panel is a rectangle, and described end plate is a ring-type.
Therefore, the present invention has following advantage: 1. and reasonable in design, simple in structure and complete practicality; 2. non-maintaining, with the large-size machine equivalent life, and help improving the large-size machine reliability of operation.
