Technical Field
The utility model relates to the technical field of air conditioners, in particular to a cross-flow fan blade resistant to thermal shock.
Background
The cross-flow fan (or cross-flow fan or cross-flow wind wheel) is widely applied to the wall-mounted split indoor unit of the air conditioner, and the working characteristics of the cross-flow fan comprise: when the impeller makes stable rotation motion, gas flows into and out of the blade cascade twice. The relative speed of the gas entering and exiting the blade grating for the first time is in deceleration movement, the relative speed of the gas entering and exiting the blade grating for the second time is in acceleration movement, and the absolute speed of the gas is in acceleration process in the whole movement process, which is the result of acting on the gas by the rotating blade grating, and the flow track of the gas flow is shown in figure 1. The first time of entering and exiting the blade grating is called an air inlet area, and the second time of entering and exiting the blade grating is called an air outlet area, so that the blade grating can be divided into an air inlet blade grating and an air outlet blade grating according to similar areas.
The through-flow fan blade is discharged through the fan blade after the air flow enters the inside of the fan blade, and static electricity is easy to be generated in the inside of the fan blade to adsorb fine particles, so that the cleaning is inconvenient.
