Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a fluid disturbance mechanism. Background Art

[0002] Heat exchangers are often used to heat low-temperature fluids or cool high-temperature fluids, vaporize liquids into steam or condense steam into liquids in industrial production such as petroleum, chemical, light industry, pharmaceutical, and energy. Heat exchangers can be a unit device, such as a heater, cooler, and condenser, etc.; they can also be a component of a process equipment, such as a heat exchanger in an ammonia synthesis tower. Heat exchangers are important unit equipment in chemical production. According to statistics, the tonnage of heat exchangers accounts for about 20% of the entire process equipment, and some even as high as 30%. Its importance can be imagined.

[0003] The flow state of the fluid inside the existing heat exchanger is relatively stable, resulting in the failure of comprehensive contact and exchange between the cold and hot fluids during circulation, resulting in low exchange efficiency. At the same time, due to the limitation of the internal volume of the heat exchanger, the traditional circular array distributed condenser tubes have the problem of small fluid exchange area. The smaller the area of ​​fluid contact exchange, the smaller the exchange rate. In view of this, we propose a heat exchanger with a fluid disturbance mechanism. Utility Model Content
