Heat exchange device based on vibration enhanced heat exchange and heat exchange device set

Abstract

The invention relates to a heat exchange device based on vibration enhanced heat exchange. The heat exchange device comprises a box body and a pipeline, a cold water pipe inlet end is arranged at thebottom of the box body, a cold water pipe outlet end is arranged at the top of the box body, a hot water pipe inlet end is arranged at the upper part of the right side wall of the box body, a hot water pipe outlet end is arranged at the lower part of the right side wall of the box body, a floating mass block is connected to the left wall surface in the box body through springs, a fixing block is arranged at the center of the inner right wall surface in the box body, slideways with dovetail grooves are symmetrically arranged on the inner front wall surface and the rear wall surface of the box body, displacement constraint blocks matched with the slideways are arranged in the slideways, the pipeline extends from the hot water inlet end into the box body from top to bottom in an S shape by atleast four layers to penetrate out of the hot water outlet end, a bent section at the left end of the pipeline is connected to the floating mass block, a bent section at the right end of the pipelineis connected to the fixing block, a plurality of resonators sleeve the whole pipeline at intervals, and the displacement constraint blocks sleeve the first layer of pipeline. According to the heat exchange device, the heat exchange efficiency is improved on the premise that the heat exchange area is not increased, the material consumption is reduced, the structure is compact, the installation isconvenient, and the heat exchange device is suitable for the aspects such as rapid cooling and waste heat recovery.

Description

technical field [0001] The invention relates to a vibration-enhanced heat exchange device, which improves the heat exchange effect of the heat exchange pipe through the vibration of the heat exchange pipe, so that it has a better heat exchange effect, and belongs to the technical field of heat exchangers. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . [0003] The volumetric heat exchanger is a heat exchanger that uses cold and hot fluids to alternately flow through the surface of the regenerator in the regenerator to exchange heat. The cold and hot fluids of the partitioned volumetric heat exchanger are separated by s...

AI Technical Summary

Problems solved by technology

The overall vibration of the pipeline can enhance the heat transfer. Although the relative movement of the pipeline is beneficial to the enhancement of heat transfer, improper handling will cause fatigue damage to the pipeline. Therefore, how can the vibration amplitude and frequency of the pipeline be adjusted more accurately and limit the pipeline to a certain extent? Pipeline fatigue damage due to excessive amplitude is worthy of further study
