Problems solved by technology

However, due to the limitations of its internal structure, the elastic tube bundle heat exchanger cannot guide the shell-side fluid so that the shell-side fluid can fully absorb heat, so its effect of enhancing heat transfer is not obvious, and it is difficult for the heat exchanger to work in practice. Realize uniform vibration of each row of tube bundles, prone to fatigue damage
Due to the rapid development of society, a large number of heat exchangers are large in size and mass, which limits their use in many high-tech fields

Abstract

The invention belongs to the technical field of heat transfer, and provides a space double-vortex-tube elastic tube bundle heat exchanger. The heat exchanger utilizes vibration to achieve enhanced heat transfer, the tube bundle is made of red copper materials instead of traditional stainless steel materials, the flexible materials are not prone to damage, the service life is prolonged, and meanwhile the tube bundle vibration can achieve the effect of automatically removing scale. A plurality of groups of double-elbow pipes are adopted in the space double-vortex pipe, so that the flowing path of shell pass fluid is increased, the shell pass fluid fully absorbs heat, and the heat transfer effect is further improved; a mass block is adopted, so that fluid is easier to vibrate at a lower speed, and enhanced heat transfer is realized; pulsating flow generated by the pulsating flow generating device impacts the mass block, so that secondary flow is generated in the vortex tube, heat transfer enhancement is further achieved, and the vibration excitation and control over the space double-vortex-tube elastic tube bundle can be achieved; the combined installation of the heat exchanger can be achieved through flanges arranged on tube pass and shell pass inlets and outlets and connecting pipes, and the heat transfer effect is enhanced.

Description

technical field [0001] The invention relates to the related field of heat exchange technology, in particular, it relates to a small double-scroll elastic tube bundle heat exchanger based on a low-velocity fluid state. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the temperature of the fluid reaches the target specified in the process. , to meet the needs of process conditions, and is also one of the main equipment to improve energy utilization, widely used in petroleum, chemical, electric power, refrigeration and other industrial fields. [0003] The internal heat transfer element of the traditional casing heat exchanger adopts a single stainless steel straight tube, which has a simple structure and low heat exchange efficiency. The heat transfer elements of the elastic tu...
