Description

Technical Field

[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used.

[0003] Most of the existing calandria heat exchangers use straight heat transfer tubes. In order to increase the contact area between the heat transfer tubes and the heat exchange medium, the heat transfer tubes are usually set longer. However, due to the limited length of the heat exchanger, the contact area between the heat transfer tubes and the heat exchange medium is limited, and the heat exchange medium is usually in a static or unidirectional flow state, which makes the temperature of the heat exchange medium in the heat exchanger shell uneven, thereby causing uneven heat exchange and affecting the heat exchange effect.
