GEA制造厂生产的增压空气冷却器,结构紧凑,压力损失小,而且应用又方便。下图为440马力柴油机上安装的冷却器元件。在这种冷却器上,靠着采用椭圆型(椭圆轴的比例为1:3)肋管的方式,以达其紧凑性。这种椭圆型冷却管与横断面面积相同的圆型冷却管相比较,其优点是:冷却管的表面面积增大了15%,而气流的阻力却减少了4/5～9/10。由于采用了矩形肋片,因而保证了冷却器容积
The charge air cooler manufactured by GEA is compact, has low pressure loss, and is easy to use. The picture below shows the cooler components installed on a 440 horsepower diesel engine. In this cooler, relying on the use of oval (elliptical shaft ratio of 1: 3) rib tube approach to its compactness. This type of oval tube has the advantage of increasing the surface area of the cooling tube by 15% and reducing the flow resistance by 4/5 to 9/10 as compared to a circular tube with the same cross-sectional area. As a result of the rectangular fins, thus ensuring the cooler volume
