Zusammenfassung: | PROBLEM TO BE SOLVED: To solve a disadvantage of conventional housings that they involve large flow losses.SOLUTION: A housing is for channelling the air flow of a radial fan (4) of an air-cooled scroll compressor (3). This housing (6) is formed by a volute (16) with an outlet (23) and an outlet bend (17) connected to the outlet with an included angle (25). The included angle (25) is an acute angle that extends from one side of a median plane (26) defined by the axis (X-X' ) of an inlet (13) and the centre (27) of an outlet (15) of the outlet bend (17) to the other side of the median plane (26) located on the side of the end point (22) of a transverse wall (20) and up to a distance (A) from this median plane (26).SELECTED DRAWING: Figure 9
【課題】大きな流れの損失を伴う従来のハウジングの欠点を解決する。【解決手段】空冷式スクロール圧縮機(3)のラジアルファン(4)の空気流を導くハウジングであって、このハウジング(6)は、出口(23)及び夾角(25)をなして出口に連結された出口ベンド(17)を備えたボリュート(16)によって形成され、夾角(25)は、入口(13)の軸線(X−X′)及び出口ベンド(17)の出口(15)の中心(27)によって定められた中間平面(26)の一方の側から横方向壁(20)の終了箇所(22)の側に位置する中間平面(26)の他方の側に且つこの中間平面(26)から距離(A)のところまで延びる鋭角であることを特徴とするハウジング。【選択図】図9 |
