Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] An airflow cooling and noise reduction device mainly includes an air duct for high-temperature airflow, which is connected to the air outlet of a compressor. As a preferred embodiment, in order to adapt to mainstream compressors, the air duct is arranged below the compressor. The exhaust air duct is fixedly installed on the base. The air duct can be set as a closed or semi-closed air duct according to actual needs. Such as figure 1 As shown, the air duct f...

Abstract

The embodiment of the invention discloses an airflow cooling and noise reduction device and a compressor. The airflow cooling and noise reduction device comprises an air duct, a passive acceleration section and a flow dividing section, wherein the passive acceleration section is fixed in the air duct and passively accelerates and cools airflow. At least one porous plate is arranged in the passive acceleration section; and the porous plate is provided with a plurality of airflow holes with the air inlet end sectional area larger than the exhaust end sectional area. According to the airflow cooling and noise reduction device provided by the invention, a step-by-step vibration reduction manner is adopted, and a two-stage vibration reduction and noise reduction scheme of passively accelerating energy attenuation and flow dividing is adopted for high-temperature and high-speed gas, so that the problem that noise and heat dissipation cannot be considered at the same time due to the too single vibration reduction and noise reduction manner in the prior art is effectively solved; and therefore, the service cycle of air-cooled products such as the compressor is effectively prolonged, and the safety of a user and the surrounding environment is guaranteed.

Description

technical field [0001] The invention relates to a temperature and noise reduction device, in particular to a temperature and noise reduction device for an air-cooled compressor of an air compressor. Background technique [0002] At present, the compressor of the air compressor will generate a lot of noise when it is working, and the compressor itself will also generate heat. In order to reduce the noise and heat, a soundproof cover and a fan will be added. The fan is cooled by air cooling to ensure that the compressor does not fail due to excessive temperature. Air cooling will cause wind noise, which will cause noise while the compressor dissipates heat, seriously affecting the environment and the health of users. [0003] Existing technical solutions have certain deficiencies in heat dissipation and noise reduction. When the heat dissipation efficiency is good, there will still be relatively large noise. On the contrary, after making a complex structure to reduce noise, th...
