Spiral baffling winding type copper pipe heat exchange device

Abstract

The invention belongs to the technical field of heat transfer, and provides a spiral baffling winding type copper pipe heat exchange device. According to the heat exchange device, the spiral structures of baffling plates are used for guiding flow of shell pass fluid in the heat exchange device, heat exchange fluid is in full contact with a heat exchange tube bundle, and the heat transfer performance of a heat exchanger is improved; the heat exchange tube bundle is excited to vibrate through fluid impact to achieve enhanced heat transfer, a copper tube is not prone to deformation, the service life can be prolonged, and the effect of automatically removing scale can be achieved while noise harm is reduced; by designing a brand-new structure, shell pass fluid is fully utilized to induce vibration to strengthen heat transfer, and the heat exchange device has the characteristic of large heat exchange area per unit volume; and in addition, through flanges and connecting pipes arranged at inlets and outlets, multi-permutation combined installation of a plurality of heat exchange devices can be achieved, and the heat exchange devices can be flexibly assembled and disassembled according to requirements of actual conditions.

Description

technical field [0001] The invention relates to the related field of heat exchange technology, in particular to a spiral baffle winding copper tube heat exchange device. Background technique [0002] The heat exchange device is a device that transfers heat between media of different temperatures. It can transfer heat from a medium with a higher temperature to a medium with a lower temperature, so that the temperature of the medium can reach the set index and improve the utilization rate of energy. With the development of science and technology, heat exchangers, as special equipment for medium heat exchange, are widely used in petroleum, chemical, pharmaceutical, nuclear power and other industries. [0003] The heat transfer elements in the heat exchange device are replaced by traditional steel pipes with copper pipes, making the heat transfer tube bundles elastic. The heat exchange device adopts fluid-induced vibration enhanced heat exchange technology, that is, the fluid i...

Problems solved by technology

[0005] However, due to the limitations of its internal structure, this elastic tube bundle heat exchange device cannot realize the diversion of the shell-side fluid, so that the shell-side fluid cannot fully absorb heat, so its effect of enhancing heat transfer is not obvious, and multiple heat exchange devices Low flexibility and single combination method when used in combination
