What are the key points to master in the specific use of the tubular cooler?

Tube coolers are used in a wide range of applications, including heating radiators for everyday use, condensers in steam turbine installations and oil coolers on aerospace rockets. It is also widely used in the chemical, petroleum, power and atomic energy industries. Its main function is to ensure that the process requires a specific temperature for the medium, but it is also one of the main equipment to improve energy efficiency. What are the main points to be mastered in the specific use of the tubular cooler?

　　Tube coolers can be divided into three categories: hybrid, thermal storage and inter-wall according to the different heat transfer methods.

　　The hybrid tube cooler is a tube cooler in which heat is exchanged through direct contact and mixing of cold and hot fluids, also known as a contact tube cooler. As the two fluids mixed heat exchange must be separated in time, this type of tube cooler is suitable for gas, liquid heat exchange between the two fluids. For example, chemical plants and power plants used in the cool water tower, hot water from the top to the bottom of the spray, while the cold air from the bottom up inhalation, in the filling of the water film surface or droplets and droplet surface, hot water and cold air in contact with each other for heat transfer, hot water is cooled, cold air is heated, and then rely on the density difference between the two fluids themselves to be separated in time.

　　Thermal storage type tube cooler is the use of cold, hot fluid alternately flow through the thermal storage chamber in the thermal storage body (filler) surface, so that the heat exchange of the tube cooler, such as the coke oven below the pre-heating air storage chamber. This type of tubular cooler is mainly used to recover and utilise the heat from high temperature exhaust gases. The same type of equipment for the purpose of recovering cold is known as accumulator coolers and is mostly used in air separation units.

　　The cold and hot fluids are separated by solid walls and heat is exchanged through the walls in the tubular cooler.
