Description
Technical Field
[0001] This utility model relates to the field of air coolers, and in particular to an air cooler with low noise. Background Technology
[0002] An air cooler is a device that uses ambient air as the cooling medium, flowing horizontally across the outside of finned tubes to cool or condense the high-temperature process fluid inside the tubes. Air coolers are an indispensable type of equipment among the numerous heat exchangers in oil refineries and petrochemical plants. Their applications encompass various conditions, including the condensation of overhead oil and gas into gasoline, diesel, heavy oil, and residual oil cooling. They also have wide applications in the chemical, power, and metallurgical industries.
[0003] Air coolers often generate a certain level of noise during operation. This noise mainly originates from the rotation of the internal fan and the aerodynamic noise generated when airflow passes through the radiator tube bundle. Although air coolers are widely favored for their high-efficiency heat exchange capacity and environmental friendliness, playing an irreplaceable role, especially in scenarios where water resources are scarce or water pollution must be avoided, the noise they generate during operation is a problem that cannot be ignored. To reduce the impact of noise on the working environment and surrounding residents, this application proposes a low-noise air cooler. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a low-noise air cooler includes an air cooler body 1, four connecting brackets 2 symmetrically fixedly installed on the air cooler body 1, and a sound insulation wall assembly 3 fitted onto the air cooler body 1, with the sound insulation wall assembly 3 fixedly connected to the connecting brackets 2. The sound insulation wall assembly 3 consists of an outer supporting base wall 5, inner sound-absorbing cotton 6, outer cone tubes 7, and inner cone-shaped sound-absorbing cotton 8. The inner sound-absorbing cotton 6 is installed on the inner wall of the outer supporting base wall 5. There are two outer cone tubes 7 symmetrically installed at the upper and lower ends of the outer supporting base wall 5. There are two inner cone-shaped sound-absorbing cotton 8, each installed on the inner wall of one of the two outer cone tubes 7. A sound-absorbing ventilation assembly 4 is fixedly inserted into the outer supporting base wall 5 and the inner sound-absorbing cotton 6. The sound-absorbing ventilation assembly 4 consists of a rectangular pipe 11, pipe sound-absorbing cotton 12, and sound-absorbing cotton partition 13. The rectangular pipe 11 is fitted onto the pipe sound-absorbing cotton. On the 12, there are several sound-absorbing cotton partitions 13, which are evenly installed on the inner walls of the upper and lower sides of the pipe sound-absorbing cotton 12. At the same time, the sound-absorbing cotton partitions 13 on the upper and lower sides are arranged crosswise. By setting a connecting bracket 2 on the air cooler body 1 and setting a sound insulation wall component 3 on the connecting bracket 2, the noise emitted by the air cooler body 1 can be blocked, thereby reducing the noise emitted by the air cooler body 1 and reducing the impact of the noise emitted by the air cooler body 1 on the working environment and surrounding residents. By setting a sound-absorbing ventilation component 4, the channel formed by several sound-absorbing cotton partitions 13 on the sound-absorbing ventilation component 4 can extend the sound wave propagation path. Therefore, the sound-absorbing ventilation component 4 can ensure the smooth airflow inside and outside the sound insulation wall component 3, thereby reducing the impact of the sound insulation wall component 3 on the operation of the air cooler body 1, and also playing a role in sound absorption and noise reduction.
[0021] Specifically, the inner sound-absorbing cotton 6 on the soundproof wall assembly 3 is fixedly connected to the outer supporting base wall 5, the outer cone tube 7 is fixedly connected to the outer supporting base wall 5, the inner cone-shaped sound-absorbing cotton 8 is fixedly connected to the outer cone tube 7, and the outer supporting base wall 5 is fixedly connected to the connecting bracket 2. Several first mounting holes 9 are symmetrically opened on the four side walls of the outer supporting base wall 5 on the soundproof wall assembly 3, and several second mounting holes 10 are symmetrically opened on the four side walls of the inner sound-absorbing cotton 6. When the soundproof wall assembly 3 is in use, the outer supporting base wall 5 provides stable support, the inner sound-absorbing cotton 6 absorbs sound wave energy and reduces penetration, the outer cone tube 7 installed symmetrically at both ends guides sound wave refraction and scattering, reducing propagation efficiency, and the inner cone-shaped sound-absorbing cotton 8 installed on the inner wall of the cone tube further captures and absorbs sound waves, especially escaping sound waves, to ensure all-round sound insulation effect.
[0022] Specifically, the sound-absorbing ventilation component 4 is inserted into the first mounting hole 9 on the outer supporting base wall 5 and the second mounting hole 10 on the inner sound-absorbing cotton 6. The rectangular pipe 11 on the sound-absorbing ventilation component 4 is fixedly connected to the outer supporting base wall 5 and the inner sound-absorbing cotton 6. The pipe sound-absorbing cotton 12 on the sound-absorbing ventilation component 4 is fixedly connected to the rectangular pipe 11. The sound-absorbing cotton partition 13 is fixedly connected to the pipe sound-absorbing cotton 12. The rectangular pipe 11 serves as a ventilation path, and the pipe sound-absorbing cotton 12 covers it, effectively absorbing the sound wave energy carried in the airflow and reducing noise transmission. The sound-absorbing cotton partition 13 is evenly and crosswise installed on the upper and lower inner walls of the pipe sound-absorbing cotton 12, further dividing the airflow, increasing the contact area between the sound waves and the sound-absorbing material, and improving the sound-absorbing effect.
