Abstract

The invention discloses a high-pressure-resistant reinforced heat transfer element adopting a staggered channel structure and a manufacturing method of the high-pressure-resistant reinforced heat transfer element. The high-pressure-resistant reinforced heat transfer element adopting the staggered channel structure is formed by stacking and combining a plurality of first high-temperature dielectricplates, a plurality of second high-temperature dielectric plates, a plurality of first low-temperature dielectric plates, a plurality of second low-temperature dielectric plates and a plurality of end plates in the plate thickness direction, wherein the first high-temperature dielectric plates, the second high-temperature dielectric plates, the first low-temperature dielectric plates and the second low-temperature dielectric plates are all metal sheets; the end plates are metal medium plates; and the first high-temperature dielectric plates, the second high-temperature dielectric plates, thefirst low-temperature dielectric plates, the second low-temperature dielectric plates and the end plates are equal in length and width. The high-pressure-resistant reinforced heat transfer element adopting the staggered channel structure is resistant to high temperature and high pressure, high in heat transfer coefficient, high in heat transfer area density and compact in structure, and metal consumption is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of heat exchange devices, in particular to a high-pressure-resistant enhanced heat-transfer element with a staggered channel structure and a manufacturing method thereof. Background technique [0002] In a gas heat exchanger, the limitation of flow resistance forces the designer to choose a lower mass flow rate, and the low mass flow rate and low thermal conductivity of the gas result in a low heat transfer rate per unit heat transfer area. Excessive heat transfer surface area is therefore a typical feature of gas heat exchangers. Under the premise that the total heat transfer power and pump power consumption are equivalent, the heat transfer area of ​​the gas heat exchanger is more than 10 times the surface area of ​​the liquid-liquid heat exchanger, condenser, and evaporator. Gas heat transfer requires a large heat transfer area density, and such surfaces that meet the requirements are called compact heat...

AI Technical Summary

Problems solved by technology

Practice has shown that in the process of high-pressure gas-gas heat transfer, the shortcomings of shell-and-tube heat exchangers such as low thermal efficiency, small heat transfer coefficient, and poor compactness are further manifested. High heat loss, large heat transfer area, bulky volume, and metal consumption The problems of high energy consumption and large thermal inertia can no longer meet the needs of users for compact, high-efficiency, flexible layout, and rapid response of heat exchange devices.
