Abstract

The invention provides a rotating rolling device for a helical baffle. The rotating rolling technology of the rotating rolling device is practical. By the adoption of the rotating rolling device for the helical baffle, according to the enhanced heat transfer mechanism of the formed helical baffle and an efficient helical baffle tube bundle formed in a matched mode, within the range of the optimized structure parameters of the helical baffle, namely beta is 0-45 degrees, the lead angle of the helical baffle can be adjusted optionally; the diameter DN of the helical baffle and the thickness of a helical baffle generated after rotating rolling is conducted meet the machining technical requirement, for the thickness of the helical baffle, of the 'tubular heat exchanger' of the GTB151-1999 standard.

Description

technical field [0001] The invention relates to the technical field of heat transfer enhancement, fluid transportation and fluid stirring, and in particular belongs to the rolling technology of spiral baffles and spiral plates and the rolling device used to realize the technology. Background technique [0002] The efficient utilization of energy is realized through new high-efficiency energy-saving technologies and high-efficiency energy-saving equipment. Enhanced heat transfer is a research hotspot in the efficient use of energy, and efficient heat exchange equipment provides a technical basis for efficient use of energy. The spiral baffle heat exchanger is a heat exchanger with high heat transfer efficiency and low flow resistance. It is matched with various high-efficiency heat exchange tubes to form a heat exchanger. There is a significant heat transfer effect. Up to now, there has not been a device capable of rolling spiral baffles, and it is extremely necessary to cr...
