Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, the fan blades of the cooling fan in the prior art are fixedly connected. When the motor is started, the air resistance of the fan blades is large, the rotation acceleration is slow and the motor load is large. At the same time, the honeycomb is wetted by drip irrigation. When using a curtain, the dispersion of water is poor, and the contact area between water and air is small, so the gasification effect of water is limited, and the cooling effect on air is poor. The present invention proposes a precision air cooler fan blade and its Casting process

Embodiment approach

[0029] As an embodiment of the present invention, a groove is provided on the arc surface of the rotating hole; an O-ring 33 is provided inside the groove, and the O-ring 33 is rotatably connected to the output shaft of the motor 15; During work, when the air flow cavity is full of atomized water, the atomized water will easily enter the inside of the sleeve 13 through the rotating hole and the output shaft of the motor 15, and then the motor 15 will be soaked, which will affect the normal use of the motor 15, and even make the motor 15 15 is short-circuited and burned, so by setting an O-ring 33 in the rotating hole, the output shaft of the motor 15 is connected to the O-ring 33 in rotation, and the inside of the sleeve 13 can be isolated from the air flow chamber, effectively preventing water from entering The inside of the sleeve 13 realizes the protection of the motor 15 .

Abstract

The invention belongs to the technical field of air cooler accessories, and particularly relates to a precise air cooler fan blade and a casting process thereof. The precise air cooler fan blade comprises a housing, a rotating ring and fan blades, wherein a cavity is formed in the housing; the rear end face of the housing is fixedly connected with a sleeve in the cavity; a motor is arranged in thesleeve; an output shaft of the motor is fixedly connected with the rotating ring through a rotating column, and the arc-shaped surface of the rotating ring is slidably connected with the fan blades which are uniformly arranged in the radial direction; and a honeycomb wet curtain and an atomizing nozzle are arranged in the housing. According to the precise air cooler fan blade and the casting process thereof, the problems that when the motor is started, the air resistance of the fan blades is large, the rotating acceleration is slow, and the load of the motor is large are effectively solved, meanwhile, after water is atomized, the contact area between the water and the air is greatly increased, so that the gasification of the water is faster, then the cooling effect on the air is stronger,the atomized water can automatically clean the fan blades, and the labor cost for cleaning the fan blades is saved.

Description

technical field [0001] The invention belongs to the technical field of air cooler accessories, in particular to a precision air cooler fan blade and its casting process. Background technique [0002] Air coolers are divided into refrigeration industrial air coolers and household air coolers. Industrial air coolers are generally used in cold storage and cold chain logistics refrigeration environments. Household air coolers are also called water-cooled air conditioners. In addition to the evaporative cooling and ventilation unit, the air cooler can not only bring fresh air and lower the temperature in corporate workshops, public places, commercial and entertainment places, but also has an important feature of energy saving and environmental protection. It is a brand new wireless Compressor, no refrigerant, no copper pipe environmental protection products, the core of the main component is the evaporative cooling pad, the evaporative cooling pad is a composite of multi-layer co...
