The invention belongs to the technical field of noise reduction, and particularly relates to a train noise reduction device which comprises a machine shell, the top of the machine shell is rotationally connected with a cover plate through a rotating shaft, and sound insulation cotton is connected to the inner wall of the machine shell in an adhesive mode; through the fan and the condensation pipe, when an engine body is started, a large amount of heat is generated in the machine shell, the water pump conveys cold water in the cold water tank to the condenser through the water inlet pipe, the condenser rapidly cools the cold water and conveys the cold water into the condensation pipe, heat exchange is conducted between the condensation pipe and the fins, and heat on the fins is rapidly conducted out; due to the design of the fan, heat dissipation of the fins is facilitated under the simultaneous action of water cooling and air cooling in the condensation pipe; due to the design of the cooling fan, heat can be conveniently and rapidly taken away; sound insulation cotton is designed, so that working sound can be conveniently blocked, and the noise influence on the outside is weakened; the sound insulation plate is arranged in the fan cover to weaken the sound in the machine shell to be emitted from the dustproof net, the rapid cooling function is achieved, and the problems that the heat dissipation demand is large and noise is large are solved.
本发明属于降噪技术领域,具体的说是一种列车降噪装置,包括机壳,所述机壳的顶部通过转轴转动连接有盖板,所述机壳的内壁均粘贴连接有隔音棉;通过风机和冷凝管,当发动机体在启动时,机壳内产生大量的热量,水泵将冷水箱内的冷水通过进水管输送至冷凝器,冷凝器迅速将冷水进行降温输送至冷凝管内,冷凝管与翅片发生热量置换,将翅片上的热量迅速导出;风机的设计,为了结合冷凝管的内,水冷和风冷的同时作用下,便于翅片的散热;散热风扇的设计,便于将热量迅速带走;设计隔音棉,便于将工作声音隔挡,减弱对外界的噪声影响;风罩内部设置隔音板减弱机壳内的声音从防尘网处散发,实现了快速冷却的功能,解决了散热需求量大噪音较大的问题。
