Description
【考案の詳細な説明】
本考案は熱交換器−のガス吸込装置、特に自動車の放熱
器に冷却空気を強制的に流過させる場合に好適な装置に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas suction device for a heat exchanger, particularly to a device suitable for forcing cooling air to flow through a radiator of an automobile.
従来のこの種装置は第１図に示され、図において１は放
熱器、２は軸流ファンの羽根車、３はエンジン、４はカ
ウリング、５はボンネツ）・を示す。A conventional device of this kind is shown in FIG. 1, in which 1 is a radiator, 2 is an axial fan impeller, 3 is an engine, 4 is a cowling, and 5 is a bonnet.
しかし７て、空気流線Ｓ１とＳ２の間の空気が放熱器１
に入る。However, the air between the air streamlines S1 and S2 is
to go into.
なお、流線間の間隔の狭い部分程流速が大きい。Note that the flow velocity is higher in a portion where the interval between the streamlines is narrower.
空気流線Ｓ１とＳ２は放熱器１を通過した後カウリング
４によって強制的に内側へ向けられるのでこの付近の流
線は密になり、流速が増大する。After passing through the radiator 1, the air streamlines S1 and S2 are forcibly directed inward by the cowling 4, so the streamlines in this vicinity become dense and the flow velocity increases.
この結果放熱器１への風速分布が悪化して放熱効率が低
下する。As a result, the wind speed distribution to the radiator 1 deteriorates, and the heat radiation efficiency decreases.
又羽根車２への風も均一に入らずファン効率を低下させ
騒音上昇の間接的原因にもなっている。Moreover, the air does not enter the impeller 2 uniformly, which reduces fan efficiency and becomes an indirect cause of increased noise.
本考案は上記に鑑み、放熱器を通過した空気を無理なく
ファンへ導入するため、放熱器からファンに到るカウリ
ング形状を空気流線を阻害しないような形状にして放熱
効率、ファン効率の向上、ファン騒音の低減を図るよう
にしたものである。In view of the above, this invention improves heat dissipation efficiency and fan efficiency by making the cowling shape from the radiator to the fan a shape that does not obstruct the air flow lines, in order to introduce the air that has passed through the radiator to the fan without any force. , which aims to reduce fan noise.
第２図には本考案の１実施例が示され、カウリング４は
熱交換器１の近傍において、熱交換器１の外周より外方
に膨出せしめられている。FIG. 2 shows an embodiment of the present invention, in which the cowling 4 is bulged outward from the outer periphery of the heat exchanger 1 in the vicinity of the heat exchanger 1.
他は第１図に示す従来のものと同様で同一部材には同一
の符号が付されている。The rest is similar to the conventional one shown in FIG. 1, and the same members are given the same reference numerals.
しかして、熱交換器１に入る最外端の空気流線Ｓ１とＳ
２は熱交換器１を流過した後カウリング４の膨出部によ
って一旦外方に向かい無理に絞られることなく流れるの
で空気速度の急激な上昇がなく流線も等ピッチとなる。Therefore, the outermost air flow lines S1 and S entering the heat exchanger 1
After flowing through the heat exchanger 1, air 2 flows outward by the bulging portion of the cowling 4 without being forced to be constricted, so there is no sudden increase in air velocity and the streamlines have a constant pitch.
従って熱交換器１の風速分布も改良されると同時にファ
ン２への風の流れも無理がないためファン効率が上昇す
る。Therefore, the wind speed distribution in the heat exchanger 1 is improved, and at the same time, the flow of air to the fan 2 is also reasonable, so that the fan efficiency is increased.
ファンへの流入空気がスムーズになるので乱れに起因す
るファン騒音も低下できる。Since the air flowing into the fan becomes smoother, fan noise caused by turbulence can also be reduced.
