空气冷却器的通风有鼓风和引风两种方式。

（1）鼓风式：空气先流经通风机后流入管束。

（2）引风式：空气先流经管束后流入通风机。

前者操作费用较经济，产生的湍流对传热好，使用较多。后者气流分布均匀，方便温度控制，噪声小，是发展的方向。热流体出口温度主要靠调节通过管束的风量来控制，即调节叶片的倾角、通风机转速和百叶窗的开启程度等。对冬季易凝、易冻的流体，可采用热风或蒸汽加热的办法调节流体出口温度。

Air cooler ventilation has two ways: blast and induced air.

(1) Blowing type: air flows through the fan first and then into the tube bundle.

(2) Induced air type: air flows first through the tube bundle and then into the fan.

The former is more economical in operation cost, good in heat transfer and more in use. The latter has uniform air distribution, convenient temperature control and low noise, which is the direction of development. The outlet temperature of hot fluids is mainly controlled by adjusting the air flow through the tube bundles, that is, adjusting the inclination angle of the blades, the speed of the fan and the opening degree of the shutters, etc. Hot air or steam heating can be used to adjust the outlet temperature of freezable fluids in winter.
