The invention belongs to the technical field of structural design of automobile air conditioner assembly parts, and relates to a mute type automobile air conditioning box structure and an automobile air conditioner, the mute type automobile air conditioning box structure comprises an air blower, a volute and a distribution box assembly, an air inlet and an air outlet of the volute are connected with the air blower and the distribution box assembly respectively, and the mute type automobile air conditioning box structure further comprises a resonant cavity, and the resonant cavity is arranged between the distribution box assembly and the volute and is connected with the volute through the neck of the resonant cavity, so that the low-frequency aerodynamic noise of a volute basin is reduced. The space between the outer surface of the volute and the outer surface of the distribution box is sealed to form an independent cavity, a resonant cavity structure is formed, and low-frequency noise in aerodynamic noise of a volute drainage basin is effectively reduced; meanwhile, grids are placed on the edge of the volute, sound absorption materials are laid to reduce medium-high frequency noise, and the purpose of integrally reducing the noise of the air handling unit is achieved.

    本发明属于汽车空调总成零部件结构设计技术领域,涉及一种静音型汽车空调箱结构及汽车空调,包括鼓风机、蜗壳以及分配箱总成,且所述蜗壳的进风口和出风口分别连接鼓风机和分配箱总成,还包括谐振腔,且所述谐振腔布置在分配箱总成与蜗壳之间,并通过谐振腔颈部与蜗壳连接,以降低蜗壳流域的低频气动噪声。本发明利用蜗壳外表面与分配箱外表面之间的空间封闭成一个独立腔体,形成谐振腔结构,有效降低了蜗壳流域气动噪声中的低频噪声;同时在蜗壳边缘放置格栅并铺设吸声材料以降低中高频噪声,实现整体降低空调箱噪声的目的。
