翻译The vertical cooler is a type of industrial heat exchange equipment. It is mainly used for system liquid cooling by utilizing the heat exchange principle among the opposing two fluids.
The vertical cooler is composed of a casing and a heat exchange tube bundle. The heat exchange tube bundle is mainly composed of an inner cylinder and a plurality of heat exchange tubes, which are arranged in an annular ring at equal intervals. The inner cylinder has an intake manifold at the bottom and an exhaust manifold at the top. The heat exchange tubes are arranged between the two manifolds and the heat exchange gas flows through the inner cylinder, while the cooling medium flows between the inner cylinder and the outer wall of the casing.
When the cooling medium flows through the heat exchange tubes, the heat exchange is performed. The thermal energy of the heat exchange gas is absorbed by the cooling medium, and the cooled heat exchange gas is ejected from the exhaust manifold. The temperature of the cooling medium after cooling continues to rise due to the continued absorption of heat from the heat exchange tube. After the cooling medium flows from the outlet of the casing to the inlet, the temperature dropping process is repeated until the heat exchange gas temperature reaches the required value.
The vertical cooler has the advantages of simple structure, small installation area, convenient maintenance and long service life, etc. It is widely used in engineering fields such as refrigeration and air conditioning industry, chemical industry, light industry, medical and sanitation industry and food industry.
竖式冷却器是一种工业热交换设备，主要是利用两种相对的流体之间的热交换原理来进行系统液体冷却。
竖式冷却器由机壳及热交换管束组成。热交换管束主要由内筒和多个热交换管组成，热交换管呈环状排列，间隔均匀。内筒底部为进气管簇，顶部为排气管簇，热交换管排列在两个管簇之间，热交换气体流经内筒，而冷却介质流经内筒和机壳外壁之间。
冷却介质流经热交换管进行热交换时，热交换气体的热能被冷却介质吸收，降温后的热交换气体从排气管簇喷出。冷却介质经冷却后的温度继续由于不断从热交换管吸收热量而升高，当冷却介质从机壳出口流向机壳进口后，重复温度降低的过程，直至热交换气体温度达到规定要求。
竖式冷却器具有结构简单，安装占地面积小，维护简单，使用寿命长等优点，因此被广泛应用于制冷和空调行业、化工行业、轻工业、医药卫生行业、食品行业等工程领域。
