CROSS FLOW FAN FOR AIR CONDITIONER |
摘要 |
PROBLEM TO BE SOLVED: To solve problems that a conventional fan is effective for improving static pressure near a side wall as a thickness distribution of a blade of a cross flow fan, but it is difficult to improve the static pressure in a whole of an air blowing passage with the conventional fan, and the improvement of air blowing efficiency cannot be expected. SOLUTION: As the thickness distribution of the blade of the cross flow fan, the thickness is gradually increased or decreased from an outer peripheral end to the inner peripheral direction, and a step is provided in an intermediate part thereof in order to set a part wherein the thickness is steeply increased. |
