Title: Muffler for cooler
Inventor: SHIMOMURA NOBUO
IPC: F25D19/00
Filed: 1990-11-21
Abstract: PURPOSE:To enable an easy and precise active control which muffles noise generated with an intervention by artificial noise by forming a machine room in a rectangular in which the dimension in one direction is set longer than that in the other direction. CONSTITUTION:A machine room 12 is shaped to open in rectangular on a backside and an opposing backside, and an opening part on the backside is closed by a machine room cover 17. An opening part on the opposing backside is closed by a partition 18, and thus, the machine room 12 provides a rectangular space closed by the machine room cover 17 and the partition 18, leaving radiation openings 17a and 18a unclosed. With respect to the dimension of the machine room 12 closed in rectangular, a width (W) and a depth (D) are set larger than a height (H), so that standing wave of noise in the machine room 12 forms in one direction, whereby the noise in the machine room 12 can be regarded as a plane travelling wave of one dimension. As a result, simplification of active control of the noise generated corresponding to driving of a compressor in the unclosed machine room and improvement in control precision can be realized.
