The invention relates to the technical field of engineering vehicles, in particular to a noise reduction and ventilation structure of a power van. The noise reduction and ventilation structure of the power van comprises a compartment and a plurality of ventilation and noise reduction mechanisms, the multiple ventilation and noise reduction mechanisms are all arranged on the peripheral wall of the compartment, and each ventilation and noise reduction mechanism comprises a main noise reduction ventilation plate and a plurality of heat dissipation and noise reduction assemblies. A plurality of mounting channels are formed in the main noise reduction ventilation plate, a fixing block is fixedly arranged at the lower end of each mounting channel, and a spherical adjusting cavity is formed in each fixing block. Each heat dissipation and noise reduction assembly is arranged at the corresponding installation channel and comprises a control panel, a resonator, a bimetallic strip and an adjusting unit. The invention provides a noise reduction and ventilation structure of a power van. The noise reduction and ventilation structure aims to solve the problems that an existing heat dissipation and noise reduction device is poor in ventilation effect and low in noise reduction efficiency.

    本发明涉及工程车辆技术领域,具体涉及一种电源车的降噪通风结构。一种电源车的降噪通风结构包括车厢和多个通风降噪机构,多个通风降噪机构设均置于车厢的周壁上,每个通风降噪机构包括主降噪通风板和多个散热降噪组件。主降噪通风板上开设有多个安装通道,每个安装通道的下端固定设置有一个固定块,每个固定块内开设有一个球形调节腔。每个散热降噪组件设置于一个安装通道处,每个散热降噪组件包括控制板、共振器、双金属片和调节单元。本发明提供一种电源车的降噪通风结构,以解决现有的散热降噪装置通风效果差,降噪效率低的问题。
