Novel heat exchanger core and distribution structure

Abstract

The invention discloses a novel heat exchanger core and a distribution structure, and belongs to the field of the chemical industry, smelting and energy power machinery. A heat exchanger provided by the invention comprises the heat exchanger core structure and the distribution structure. The core structure comprises two basic structural forms and reinforced variant forms thereof; the core structure formed by triangular waved plates and independent thin flat plates and the core structure formed by rectangular waved plates are adopted as the basic structural forms; according to the reinforced variant forms, wall surface ripples are added, and straight flow channels are changed to S-shaped flow channels. The heat exchanger composed of the core structure has the characteristics that cold-hot fluid heat exchange surfaces are wrapped mutually, and the heat exchange area of the unit volume is larger. A center-parting plate form is adopted by the distribution structure provided by the invention, so that the distribution structure has the characteristics that processing is simple, and work is reliable. Meanwhile, three layout schemes for cold-hot flow inlet-outlet channels are provided by the invention according to the distribution structure, and good reference is provided for solving actual project problems.

Description

technical field [0001] The invention belongs to the fields of chemical industry, smelting, and energy power machinery, and relates to all equipment used in heat exchangers, and specifically relates to aspects such as waste heat recovery, nuclear energy, solar energy, geothermal energy, and ocean thermal energy utilization. Background technique [0002] The energy crisis that broke out in the world in the 1970s has effectively accelerated the development of heat transfer enhancement technology. Today, energy issues are still a major problem facing mankind. No matter what kind of power equipment or heat interaction equipment, as long as it involves the use of heat energy, it is basically inseparable. Opening heat exchangers, and heat exchangers occupy an important position in today's industrial production equipment, how to use heat energy more efficiently will be of great significance to energy saving, emission reduction and sustainable scientific development, and some equipmen...

AI Technical Summary

Problems solved by technology

[0005] However, domestic publicly available relevant information shows that the research of engineers on this kind of high-compact primary surface heat exchanger still stays on the structure of the symmetrical corrugated plate core body, and as for the shunt structure, there is no public information mentioning it yet.

[0006] The absence of a reliable and public shunt structure has also led to the slow application of this symmetrical corrugated plate high-compact primary surface heat exchanger in domestic industrial development. At present, domestic public information only shows that Shanghai Jiaotong University has related work, but there is no public shunt structure.
