A hot melt type gas-liquid two-phase heat exchanger

Abstract

The invention relates to a hot-melt type gas-liquid two-phase heat exchanger, which includes a core, a sealing wall, a drainage assembly and a baffle assembly, wherein the core includes a first core and a second core, and the first Both the core body and the second core body are provided with a plurality of gas flow channels and liquid flow channels, and the gas flow channels and liquid flow channels are all 3D spiral channel structures. The drainage component introduces the liquid into the liquid flow channel in the first core body, and draws out the liquid in the liquid flow channel of the second core body; the baffle component turns the liquid in the liquid flow channel in the first core body back into the second core body in the liquid flow path. Compared with the existing technology, the heat exchanger 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. It improves the heat exchange efficiency and reduces the loss of materials, and solves the technical bottleneck problem that the heat exchange capacity of existing heat exchangers is difficult to improve.

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.
