Casing heat exchanger with irregular-shaped inner tube

Abstract

The invention discloses a casing heat exchanger with an irregular-shaped inner tube, and relates to the technical field of heat exchangers. The exchanger comprises a heat exchanger body, a flange anda collecting mechanism, one end of the heat exchanger body is provided with a first interface, a second interface is screwed to the heat exchanger body, a cold fluid outlet is formed in one side of ahot fluid inlet, and a hot fluid inlet baffle plate is internally embedded with a hot fluid tube. According to the casing type heat exchanger, through the arrangement of spiral winding between a firstcooling tube and a second cooling tube, a hollow cooling outer tube is enclosed therebetween, the mutual cooperation between the outer tube and a third cooling tube, multi-directional heat exchangingis conducted on a heat flow fluid passing therethrough, the arrangement of the spiral winding manner can prolong the time for the cooling fluid to flow inside the heat exchanger, possibility is provided for the sufficient exchange between the cooling fluid and the heat flow fluid, and the use performance of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a casing heat exchanger with special-shaped inner tubes. 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] A jacketed heat exchanger disclosed in the Chinese invention patent application publication CN103697724B, although compared with the prior art, the jacketed heat exchanger separates the garbage from the medium through the jacketed structure of the single-tube assembly , using the indirect heating method to rapidly improve the heat exchange effect and save energy, easy to disassemble and maintain through ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a sleeve-type heat exchanger with a special-shaped inner tube, which solves the problem that the sleeve-type heat exchanger proposed in the above-mentioned background technology cannot be used for extending the flow of cold and hot fluids in the heat exchanger. The time of internal flow affects the efficiency of heat exchange between hot and cold fluids, and because it cannot reduce the amount of air bubbles attached to the pipe wall inside the fluid, it will cause a relatively serious degree of oxidation on the inner wall of the pipe, thus affecting the use of the pipe Shortcomings such as impact on lifespan
