Problems solved by technology
When the motor 10 and the cooler 20 are running at the same time, the noise generated by the motor 10, especially the high-speed motor, will be transmitted to the environment through the cooler 20, and the cooler 20 itself will also generate noise, resulting in the total noise of the entire motor. High, does not meet the requirements of environmental noise

Embodiment Construction
[0019] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] Figure 1 ~ Figure 4 Including housing 1, perforated circular plate 2, ultra-fine glass wool 3, glass cloth 4, perforated conical plate 5, mesh plate 6, flange 7, air inlet 8, motor 10, inner air path 11, motor fan 12. Cooler 20, air outlet 21, external air path 22, cooler fan 23, air inlet 24, muffler cover 30, etc.
[0021] Such as image 3 , Figure 4 As shown, the present invention is a motor cooler air inlet muffler cover 30, which includes a cylindrical shell 1 with one end open and the other end closed. The shell 1 is preferably cylindrical.
[0022] The side wall of the housing 1 is provided with an air inlet 8, and there are multiple air inlets 8, which are evenly distributed on the side wall of the housing 1, and the size and quantity of the holes depend on the size of the outer diameter of the housing 1. A net plate 6 i...

The invention relates to a noise reducing cover for an air intake of a motor cooler. The noise reducing cover comprises a cylindrical shell with one end opened and the other end closed, wherein an air intake is formed on the sidewall of the shell; a perforated circular plate and a perforated tapered plate are fixed inside the closed end of the shell; the perforated tapered plate is located at the middle part of the perforated circular plate and the vertex of the perforated tapered plate faces the open end of the shell; and a sound absorption material is arranged between each of the perforated circular plate and the perforated tapered plate and the closed end of the shell. The noise reducing cover of the motor cooler air intake is added without changing the previous structure of the cooler air intake; the perforated plates and the sound absorption material are arranged inside the noise reducing cover so that the air intake noise of the cooler can be reduced in multiple ways; as a result, the running noise of the motor is reduced.
Description
technical field [0001] The invention relates to a cooler of a motor, in particular to a sound-absorbing cover for the air inlet of the air-to-air cooler of the motor. Background technique [0002] The motor cooler is the main heat exchange part of the motor and an important product to maintain the operation of the motor, which directly affects the temperature rise, output and life of the motor. Among them, the air-to-air cooler is a commonly used cooler with air as the cooling medium. [0003] The cooling principle of air-to-air cooler is as follows: figure 1 As shown, the cooler 20 is installed above the motor 10, and a cooler fan 23 is installed at the air inlet 24 of the cooler 20, and an external air passage 22 is formed between the air inlet 24 and the air outlet 21 of the cooler 20; the motor 10 A motor fan 12 is installed inside, and an internal air passage 11 is formed between the motor 10 and the cooler 20 . The inner air passage 11 brings the heat generated insi...
