Technical Field
[0001] The utility model belongs to the technical field of refrigeration equipment, and particularly relates to a low-noise and high-strength air cooler. Background Art
[0002] An air cooler is a machine that passes air through a cooling medium within a chassis, generating a cooling effect through air ducts. Due to their low price, air coolers are widely used for cooling homes and factories. Existing air flow primarily relies on the rotation of an impeller driven by a motor to drive the air out. This process often produces considerable noise due to the interference of air within the chassis, and reducing this noise is a topic of research for those skilled in the art. Furthermore, motor installation and improving the structural strength of the impeller under high wind forces are also areas of research for those skilled in the art.
[0003] Chinese utility model patent No. 202320169984.0 discloses a multi-speed speed-adjustable air-cooling fan, which belongs to the technical field of air-cooling fans; it includes a drive assembly, a fan assembly, and a synchronous belt, the drive assembly includes a drive motor and a drive wheel, the fan assembly includes an impeller body and a blade assembly, the impeller body includes a shell, a drive hole is provided at the axis of the shell, a drive shaft of the blade assembly is inserted into the drive hole of the shell, the drive shaft and the drive hole are connected by a key, the shell is evenly provided with four fan-shaped grooves around the drive hole, the fan-shaped impeller petals are slidably connected inside the fan-shaped grooves, the outer arc surface of the impeller petals extends to the outside of the fan-shaped grooves, the synchronous belt is sleeved on the impeller body and the outside of the drive wheel, two adjustment gears are rotatably connected inside the fan-shaped grooves, an adjustment rack is fixedly provided on the inner arc surface of the impeller petals, the adjustment rack is located between the two adjustment gears and meshes with the two adjustment gears; it solves the problem that the speed adjustment cost of the current air-cooling fan is high and the adjustment is difficult, but it does not provide technical advice on reducing the noise of the air cooler. Utility Model Content
[0004] The utility model provides a low-noise and high-strength air cooler with a simple structure and convenient installation.
[0005] A low-noise, high-strength air cooler includes a chassis for the air cooler, with an impeller driven by a motor installed inside the chassis. The center of the impeller is vertically connected to the drive shaft at one end of the motor, and the other end of the motor is connected to a motor mounting base. The motor mounting base is a one-piece horizontal frame. A motor mounting ring is provided at the center of the horizontal frame. The motor mounting ring is divided into an inner mounting ring and an outer mounting ring. The outer mounting ring is connected to the outer frame of the horizontal frame via an integrated mounting plate. The outer mounting ring is connected to the inner mounting ring via fixed blades. The inner side of the inner mounting ring is connected to the motor. This low-noise, high-strength air cooler uses the one-piece horizontal frame as the motor mounting base, which not only facilitates the connection of the motor but also forms two air flow paths through the impeller and fixed blades of the upper and lower structures. The air flow path formed by the rotation of the impeller is adjusted in direction by the fixed blades, changing the traditional air flow direction and reducing the impact of irregular wind direction on the chassis and air duct, thereby reducing the operating noise of the entire air cooler. The one-piece horizontal frame also increases the overall structural strength of the air cooler.
[0006] An air inlet is provided on the side of the chassis, a base is installed at the bottom of the chassis, the top of the chassis is connected to the air duct base through a motor mounting seat, and the air duct base is connected to the air outlet through the air duct to facilitate adjustment of the air outlet direction of the air cooler.
[0007] The impeller is formed by integrally injecting two or more blades through an impeller ring. The impeller ring is connected to the shaft sleeve through reinforcing ribs, and the shaft sleeve is sleeved with the drive shaft to form an impeller structure with good overall structural strength. Arc-shaped blade reinforcement ribs are provided on one side of the blade to prevent the blade from
[0008] One side of the fixed blade is provided with a fixed blade reinforcement rib. The fixed blade is connected to both the outer and inner mounting rings with an integral arc-shaped connecting rib. The inner side of the inner mounting ring is provided with an integral, inwardly protruding mounting rib that securely connects to the motor, facilitating secure installation of the motor.
[0009] The utility model installs the motor in mid-air through a horizontal frame of an integrated structure. The fixed blades above the motor cooperate with the impeller below the motor to form an impeller air passage that is balanced up and down, and the fixed blades with flow direction adjustment form an air passage, which reduces the air flow noise of the air cooler and improves the overall structural strength.
