专业cooling tower组件包括冷水盆，冷却塔结构，填充物，漂移消除器，冷却塔风扇，水配送管道，风扇甲板和风扇缸，冷却塔百叶窗，变速箱，驱动轴和机械设备支撑，阀门，喷嘴和电气和仪表系统。让我们详细了解它们。
Fills:
冷却塔填充物是可用于从热水到冷空气的热传输的主要传热区域。有两种类型的填充物可用，即飞溅填充和胶片填充物。飞溅填充了从垂直方向瓦解的热水，它使水分裂以通过下一水平的飞溅条。薄膜填充薄的垂直水膜，使空气接触以帮助传热。填充物通常由PVC，聚丙烯或木材制成。
Drift Eliminators:
The purpose of Drift eliminator is to reduce the drift loss in the cooling tower. Drift eliminators normally kept next to fills in the air flow path thereby reducing the drift loss. Drift loss is the loss of entrained water through the hot air to atmosphere. Drift eliminators normally made up of PVC. More number of passes through drift eliminator decreases the drift loss but increases the pressure drop thereby increasing fan power consumption.
Cold Water Basin:
冷水盆通常由钢筋水泥混凝土（RCC）组成。它有两个功能。一种是从塔中收集冷水并充当存储。另一个是强大的，它是冷却塔主要结构的基础。冷盆地要么位于土壤的顶部，要么位于地面以下。冷却塔的高度是从冷盆地顶部到风扇组件之间的距离确定的。
冷却塔结构：
大多数塔楼由化学处理的木材组成，而RCC和纤维增强塑料（FRP）冷却塔也根据用户的要求提供。
冷却塔Fans:
冷却塔的主要部分组件。冷却塔fans are normally made from Aluminum, Fiber Reinforced Plastic (FRP), Glass fiber and hot-dipped galvanized steel are commonly used as fan materials. FRP being light in weight, impellers made up of FRP reduces the power requirements of the fan. The cooling tower fan blades pitch angle is varied depending on seasonal requirements.Cooling tower Fan blade Pitch angle is the angle made by the fan with the plane. Normally during the summer season, the air density is low. So the fan blade pitch angle is increased to increase the capacity of the fan.
水分配管道：
冷却水将管道分配到热盆地必须被埋在地下或支撑在地面上，以避免由于管道内部的自重和水压而导致塔的挤压。单个细胞入口管道将得到独立支持。
风扇甲板和风扇缸：
风扇甲板提供了一个平台，以支持风扇缸，并作为对风扇和水分配系统的访问方式。
风扇缸的风格形状，以增强塔的正确流动。风扇叶片尖端和风扇圆柱之间的间隙应少于最大效率。
冷却塔组件 - 百叶窗：
百叶窗由石棉纸组成。它有两个目的。一种是将循环水保留在塔中，另一种是将气流平均分配到填充物中。
变速箱，驱动轴和机械设备支持：
The drive shaft transmits power from the output shaft of the motor to the input shaft of gear reduction units. Gearbox reduces the speed of the depending on the fan requirement. Torque tube unitized supports gives permanent alignment of the motor, driveshaft & gear reducer.
Distribution Valves:
分布阀用于调节热水流以均匀分布在细胞中。插座开放气氛。阀体的设计旨在承受不利的腐蚀环境。阀应构成最小压降。
喷嘴：
塑料被广泛用于喷嘴。许多喷嘴由PVC，ABS，聚丙烯和充满玻璃的尼龙制成。喷嘴用于在冷却塔的电池内提供均匀的热水分布。该设计的最新进展涉及一个非关闭类型喷嘴。
冷却塔Fan Motor:
Explosion proof motors are preferred for use in Petrochemical & Refinery cooling tower applications. As the Hot Cooling water from exchangers may have explosive gas if a heat exchanger is leaky. The motor is to be provided with Protection systems like Earth fault relay and overload relay etc.
冷却塔仪器：
Vibration Switches, Low Oil Level Switches, Level Switches for Hot & Cold Water Basin, Thermocouples for Hot & Cold Water Temperature measurement and Flow meters for Cooling water makeup & Blowdown rate are normal instrumentation system available in any cooling tower.
