    • The invention refers to a resonator arrangement for the cabinet of a refrigeration appliance, said cabinet (3) defining a housing (1) and carrying, in the latter, a compressor (2) presenting a hermetic casing (2a) and a defrost water evaporating tray (10) comprising: a bottom wall (11), to be seated onto an upper portion of the casing (2a) of the compressor (2); and a peripheral wall (12) superiorly projecting from the bottom wall (11), at least one of the peripheral wall (12) and bottom wall (11) of the evaporating tray (10) carrying a noise absorbing means turned to a noise generation region in said housing (1) and being dimensioned to define a certain reactive impedance and a certain dissipative impedance in the medium of the housing (1) for a determined frequency band.
    • 本发明涉及一种用于制冷设备的机壳的谐振器装置,所述机柜(3)限定一个壳体(1),并在其中承载一个呈现密封壳体(2a)的压缩机(2)和蒸发的除霜水 托盘(10)包括:底壁(11),其被安置在压缩机(2)的壳体(2a)的上部上; 和从底壁(11)上突出的周壁(12),带有噪声吸收装置的蒸发托盘(10)的周壁(12)和底壁(11)中的至少一个转向噪声产生 所述壳体(1)中的区域的尺寸设计成在所述壳体(1)的介质中限定一定的无功阻抗和一定的耗散阻抗,用于确定的频带。
