Heat exchanger

Abstract

The invention belongs to the technical field of heat exchangers, in particular to a heat exchanger. The heat exchanger comprises a casing, a right end cover, a cold water inlet pipe, a hot water inletpipe, a cold water outlet pipe, a hot water outlet pipe, a U-shaped heat exchange partition plate, a rotating module and the rack, wherein the cold water inlet pipe is arranged at the upper right endof the casing; the cold water outlet pipe is arranged at the lower left end of the casing; the right end cover is fixedly connected to the right end of the casing; the U-shaped heat exchange partition plate is arranged in a cavity formed by the casing and the right end cover and is a corrugated plate; the hot water outlet pipe is arranged at a bend of the U-shaped heat exchange partition plate; the right end cover is provided with the hot water inlet pipe; the end face of one end of the U-shaped heat exchange partition plate is fixedly connected to the inner side of the right end cover; the other end of the U-shaped heat exchanger partition plate is fixedly connected to the rack; the rack is slidably mounted on the hot water inlet pipe; the rotating module is arranged on the right side ofthe cold water inlet pipe; the rack is controlled to slide through the rotating module so as to drive the U-shaped heat exchange partition plate to shake, cold liquid and hot liquid in the casing areoscillated during shaking, and the heat exchange effect is improved.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a heat exchanger. Background technique [0002] A heat exchanger, also known as a heat exchanger, is a device used to transfer heat from a hot fluid to a cold fluid to meet the specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Heat exchangers are common equipment in chemical industry, petroleum, power, food and many other industrial sectors, and play an important role in production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are more widely used. According to the principle and method of heat exchange between cold and hot fluids, they can basically be divided into three categories: Partitioning wall type, hybrid type and heat storage type, among the three types of heat exchangers, partitioning wall heat exchangers are the most widel...

AI Technical Summary

Problems solved by technology

[0003] The characteristic of the existing partition heat exchanger is that the cold and hot fluids are separated by a layer of solid wall (tube or plate), do not mix, and exchange heat through the partition, but the heating surface is limited by the wall of the container, and the heat transfer is limited. The coefficient is not high; in the process of heat exchange, the fluid flow is not sufficient, which restricts the efficiency of heat exchange
