Inventor: KOBAYASHI TAKAHITO
IPC: B01D39/14
Filed: 1991-09-17
Abstract: PURPOSE:To obtain a laminated filter medium for streamer type filters with low pressure loss and high removal efficiency by making at least one layer on the downstream side of electret nonwoven fabrics with the prescribed METSUKE (unit weight) and letting the measured bending resistance take the limited value. CONSTITUTION:Unwoven fabrics of 10-200g/m<2> METSUKE (unit weight) are used as base material for electret nonwoven fabrics. Nonwoven fabrics of 0.5-18 fineness and 0.03-0.15cc/cc denier fiber density are used for a dust holding layer laminated on the upstream side so that the dust holding layer may have fineness gradually smaller from the upstream to the downstream side and have multilayer structure with a fiber density gradient. Fiber layers are made to adhere to each other by lamination using needle punching treatment, spot deposition treatment, adhesion by heat fusion fiber or binders, etc., and the bending resistance of the laminated filter medium for filters is <=20mm. Fiber packing density is determined by the following formula after measuring METSUKE of fiber layer, W g/m<2> and thickness on putting no-load, T cm. Fiber packing density, cc/cc=WX10<-4>divided by (TXrho), where rho is density of fiber, g/cc. The bending resistance is measured in accordance with JIS L1096, 'Testing Methods for Woven Fabrics, Bending Resistance'.

Title: Heat exchanger
Inventor: TANAKA JUNICHIRO
IPC: F28F1/32
Filed: 1988-10-24
Abstract: PURPOSE:To improve heat transfer ratio of a fin by inclining the slit fin with respect to the fin board face, and inclining reversely the air flow upstream side and air flow downstream side with respect to the center line of the air flowing direction of the fin board. CONSTITUTION:In a crossfin type heat exchanger in which parts of a flat platelike fin board 2 are cut and erected in a bridge state to provide many slit fins 5,..., the fins 5 are inclined with respect to the face of the board 2, and the air flow upstream side and the air flow downstream side are inclined reversely with respect to the center line l of the air flowing direction of the board 2. Since the fins 5 are inclined at the board 2, the airflow collided with the front ends of the fins 5 does not affect temperature influence to the rear fins 5, and front edge effect is effectively performed. Since the inclining directions are reversely set at the air flow upstream and downstream sides, the air flow is altered in the flowing direction near the center line l while maintaining the laminar flow state to increase the heat exchanging amount due to the mixture of the air flows.
