Embodiment Construction

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0035] Such as figure 1 As shown, an adjustable electronic fan order noise analysis system includes an adjustable noise collection platform and an adjustable rib layout structure 5, and the adjustable noise collection platform includes a retractable microphone fixing frame 2, a sampling device 3, and a fan fixing frame 4. A microphone 1, that is, a condenser microphone, is installed on the retractable microphone holder 2, which converts sound pressure into an electrical signal. The retractable microphone holder 2 is used to adjust the height of the microphone to meet the height requirements of different test methods. The microphone 1 is electrically connected to the sampling device 3, and the sampling device 3 is us...

Abstract

The invention relates to an adjustable order noise analyzing system for an electronic fan. The system comprises an adjustable noise collecting platform and an adjustable rib arranging structure, wherein a microphone is mounted on a telescopic microphone fixing rack, the microphone is electrically connected to sampling equipment, a height adjusting device is mounted on a fan fixing rack, the electronic fan is mounted on the height adjusting device, the height adjusting device is suitable for adjusting height of the electronic fan, the electronic fan comprises the adjustable rib arranging structure, a motor is mounted on a wheel hub substrate, a connecting ring is arranged outside the wheel hub substrate in a sleeving manner, a plurality of first sub buckling parts in a circumferential arrayare arranged outside the connecting ring, a middle hole is formed in the middle of a wind ring base plate, a plurality of fixed seats are mounted on the wind ring base plate, a second sub buckling part is arranged on each fixed seat, and a plurality of free ribs are connected between the wind ring base plate and the connecting ring. The adjustable order noise analyzing system for the electronic fan is convenient to adjust and test and can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of electronic fan noise detection and analysis, in particular to an adjustable electronic fan order noise analysis system. Background technique [0002] An electronic fan is an automotive component that drives the fan blades to rotate through an electric motor to achieve heat exchange for the cooling module. Electronic fans are mainly composed of fan blades, motors, wind protection rings and other components. Electronic fans are usually accompanied by noise during use. The order noise of the electronic fan is closely related to the rib distribution of the windshield. [0003] Traditional development is based on the evaluation and optimization of the test results of mold parts. However, the modification of the mold is often difficult, the cycle is long, and the cost is high, which cannot meet the current low-cost, fast-paced development needs. Therefore, there is a need for an adjustable electronic fan or...
