Fin for train heat exchanger

Technical Field

The utility model relates to a heat exchanger technical field specifically is a fin for train heat exchanger.

Background

The heat exchanger is an energy-saving device for transferring heat between materials between two or more fluids with different temperatures, and is used for transferring heat from the fluid with higher temperature to the fluid with lower temperature to make the temperature of the fluid reach the index specified by the process so as to meet the requirements of process conditions, and is also one of main devices for improving the utilization rate of energy. The heat exchanger industry relates to more than 30 industries such as heating ventilation, pressure vessels, reclaimed water treatment equipment, chemical industry, petroleum and the like, and an industrial chain is formed mutually. Heat exchangers are often used in petroleum, chemical, light industry, pharmaceutical, energy and other industrial processes to heat a low temperature fluid or to cool a high temperature fluid, to vaporize a liquid into a vapor, or to condense a vapor into a liquid. The heat exchanger can be a unit device such as a heater, a cooler, a condenser and the like; or may be an integral part of a piece of process equipment, such as a heat exchanger in an ammonia synthesis column. The heat exchanger is an important unit device in chemical production, and according to statistics, the tonnage of the heat exchanger accounts for about 20 percent of the whole process equipment and even reaches 30 percent, and the importance of the heat exchanger is conceivable.
