Hot melt type gas-liquid two-phase heat exchanger

Abstract

The invention relates to a hot melt type gas-liquid two-phase heat exchanger. The exchanger comprises a core, a sealing wall, a drainage assembly and a baffle assembly, wherein the core comprises a first core and a second core, both the first core and the second core are provided with a plurality of gas flow channels and liquid flow channels, and the gas flow channels and liquid flow channels areboth of a 3D spiral channel structure. The drainage assembly introduces the liquid into the liquid flow channels in the first core, and draws the liquid in the liquid flow channels of the second core;and the baffle assembly turns the liquid in the liquid flow channels in the first core back into the liquid flow channels of the second core. Compared with the prior art, the heat exchanger in the invention significantly improves the heat exchange efficiency on the basis of one-time molding, can greatly reduce the utilization rate of materials, and can adjust the gas-liquid ratio according to thedemand, thereby greatly improving the heat exchange efficiency and reducing the material loss, and solving the technical bottleneck problem of the existing heat exchanger that is difficult to improvethe heat exchange capacity.

Description

technical field [0001] The invention relates to the field of heat exchangers, in particular to a hot melt type gas-liquid two-phase heat exchanger. Background technique [0002] Gas-liquid heat exchangers are widely used in industrial production processes, and their functions include gas or liquid preheating and heating, liquid or gas residual heat recovery, etc. Gas-liquid heat exchangers include double-tube, shell-and-tube, and plate frame structures. [0003] At present, although there are various types of heat exchangers commonly used in the market, most of them have similar structures. Due to the requirements of industrial production, most parts need to be produced separately, and the method of subtractive manufacturing is required, which leads to complex issues such as the difficulty of sealing and production of equipment parts. [0004] In the existing gas-liquid heat exchange, most of the gas-liquid flow channels are independently designed, that is, two independent...

AI Technical Summary

Problems solved by technology

However, the surface area of ​​the material in the gas-liquid heat exchanger is much larger than the heat exchange area, which makes it difficult to improve the utilization rate of the heat exchange material in the heat exchanger, and the heat exchange capacity cannot be further improved.
