Problems solved by technology

[0003] The present invention provides a new heat exchanger and heat exchange mechanism, which intends to solve the problem that the heat exchange temperature cannot exceed 600°C due to the limitation of the heat resistance of metal materials, so that the heat exchange carrier can operate at ≥1000°C and a wide pressure difference ( 0.05Mpa~35Mpa), it can also run stably, safely and reliably for a long time

Abstract

The invention discloses a heat exchanger suitable for high temperature and wide pressure difference as well as a heat exchange mechanism. The heat exchange mechanism comprises a cylinder body, a corecolumn and a plurality of unit layers, wherein the cylinder body has a cylindrical structure; the core column and the cylinder body are coaxially arranged, and the outline of the core column is cylindrical; each unit layer comprises a plurality of rotary cylinders which surround the core column uniformly and are parallel with the core column; a plurality of unit layers are sequentially arranged onthe core column and are clamped between the core column and the cylinder body; the rotary cylinders positioned on the same layer have the same diameter; and each layer of rotary cylinders have the same number and are arranged uniformly. The heat exchanger and the heat exchange mechanism have high heat exchange efficiency and can be applied to heat exchange scenes with high temperature and wide pressure difference.

Description

technical field [0001] The invention relates to the field of high-temperature heat exchange in the heat transfer aspect of special engineering, in particular to a heat exchanger suitable for high temperature and wide pressure difference and a heat exchange mechanism thereof. Background technique [0002] The heat exchange method of the traditional wall heat exchanger is that the cold and hot working fluid are separated by the metal tube wall, and the heat must penetrate the metal tube wall and conduct from one side of the metal tube wall to the other side to complete the heat exchange process. , but this heat transfer method and the corresponding heat transfer temperature of the heat exchanger cannot be higher than 600°C due to the heat resistance of the metal material. When the heat transfer temperature is higher than 600°C, the temperature of the metal tube wall will also be high At 600°C, creep of metal materials will occur (caused by the decrease of yield strength), and ...
