A hot melt type gas-liquid two-phase heat exchange core structure

Abstract

The invention relates to a hot-melt type gas-liquid two-phase heat exchange core structure, which includes a first core and a second core, and a plurality of gas flows are provided in the first core and the second core. channel and liquid flow channel; the gas flow channel and the liquid flow channel are 3D spiral channel structures; the extension length directions of the 3D spiral channel corresponding to the gas flow channel and the liquid flow channel are perpendicular to each other; to be heat exchanged After the liquid flows through the liquid channel of the first core, it can flow into the liquid flow channel of the second core through the peripheral guide components; the gas to be heat-exchanged flows through the second core and the first core through the gas channel to complete the gas- Liquid heat exchange. Compared with the existing technology, the heat exchange core in the present invention significantly improves the heat exchange efficiency on the basis of one-time molding, and can greatly reduce the usage rate of materials, and can adjust the gas-liquid ratio according to the demand, which is extremely high. It greatly improves the heat exchange efficiency and reduces material loss, and solves the bottleneck problem that the heat exchange performance of the traditional heat exchange core cannot be improved.

Description

technical field [0001] The invention relates to the field of gas-liquid heat exchangers, in particular to a hot-melt type gas-liquid two-phase heat exchange core structure. 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 exchanger cores 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] Most of the existing gas-liquid heat exchange cores adopt the independent design of the gas-liquid fl...

AI Technical Summary

Problems solved by technology

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 of the heat exchange material in the heat exchanger, and cannot overcome the bottleneck problem of further improving the heat exchange performance
