[0002] The existing cross-flow fan blades are composed of several separate fixed cross-flow blade structures. After the fixed cross-flow blade structure is installed and fixed according to the installation angle, it is in a completely fixed state, and the fixed cross-flow blade structure cannot be adjusted. entrance and exit angle
However, in reality, cross-flow fan blades often operate in different working conditions, and under the same working condition, different blade structures have different operating efficiencies due to the asymmetric internal flow, which makes it impossible for cross-flow fan blades to operate under different operating conditions. Different working conditions, changing the inlet and outlet angles of the blade structure, it is difficult to fully exert the efficiency of each blade structure, and it is difficult to guarantee the efficiency of the cross-flow fan, which has a great impact on the performance and noise of the cross-flow fan, and its various performances need to be improved

The invention relates to a through-flow blade structure, a through-flow fan blade, a through-flow fan and an air conditioning unit, wherein the through-flow blade structure comprises a blade base frame and movable blades; mutually matched arc sliding guide structures are arranged on the blade base frame and the movable blades; and under different working conditions, through the arc sliding guide structures, the movable blades can move relative to the blade base frame along the arc direction to adjust an angle of an inlet and outlet. A fixed integral blade structure in the prior art is set to two parts able to be adjusted freely and movably, and under the different working conditions, through the arc sliding guide structures, the movable blades can move relative to the blade base frame along the arc direction, so that the angle of the inlet and outlet of the through-flow blade structure can be automatically adjusted according to the differences of loads in the practical working condition, to be adapted to a position point of the corresponding working condition, and the efficiency of each through-flow blade structure is effectively ensured.
Description
technical field [0001] The invention relates to the field of fans, in particular to a cross-flow blade structure, a cross-flow fan blade, a cross-flow fan and an air-conditioning unit. Background technique [0002] The existing cross-flow fan blades are composed of several separate fixed cross-flow blade structures. After the fixed cross-flow blade structure is installed and fixed according to the installation angle, it is in a completely fixed state, and the fixed cross-flow blade structure cannot be adjusted. Entry and exit angles. However, in reality, cross-flow fan blades often operate in different working conditions, and under the same working condition, different blade structures have different operating efficiencies due to the asymmetric internal flow, which makes it impossible for cross-flow fan blades to operate under different operating conditions. Different working conditions, changing the inlet and outlet angles of the blade structure, it is difficult to fully e...
