COLD/COOL/WARM HEAT DIFFUSION PREVENTIVE BELLOWS-SHAPED TUNNEL TYPE BLOWER

摘要

PROBLEM TO BE SOLVED: To provide a cold/cool/warm heat diffusion preventive bellows-shaped tunnel type blower, preventing diffusion of cold/cool/warm heat air of an inside heating/cooling instrument by easily changing a supply air direction according to an expanding/contracting and bending installation angle of a bellows-shaped folding tunnel having a large bore, and improving heat efficiency of a large capacity.;SOLUTION: A bellows-shaped folding tunnel side wall having a structure superimposed in a plurality of stages is provided on a set provided with a two-stage structure capable of adjusting high and low positions, and forming an arc shape, thereby facilitating expanding/contracting and bending angle change.;COPYRIGHT: (C)2003,JPO
