Special-shaped microchannel heat exchange tube type design method, computer equipment and storage medium

Abstract

Special-shaped microchannel heat exchange tube design method, computer equipment and storage medium, the heat exchange tubes arranged in the cylindrical heat exchanger are all Archimedes spiral heat exchange tubes, and the minimum air in the cross section of the heat exchanger is set Flow area ratio, given the outer diameter of the heat exchanger, the wall thickness of a single heat exchange tube, and the inner diameter of the tube; determine the arc length and heat exchange area of ​​a single heat exchange tube; select basic variables, and determine the search area for each basic variable; According to the inner diameter of the heat exchanger, the wall thickness of a single heat exchange tube and the inner diameter of the tube, determine the number of heat exchange tubes that can be arranged in the heat exchanger, and the total heat exchange area of ​​the heat exchanger is the total heat exchange area of ​​all heat exchange tubes; In the search area, search for the optimization scheme that the actual air flow area ratio meets the set conditions and can obtain the maximum total heat exchange area of ​​the heat exchanger. The present invention only needs to know several basic parameters of the heat exchanger to obtain the tube type, layout and quantity of a single heat exchange tube with the largest heat exchange area, and provides a tube type design premise for the optimal design of the heat exchanger.

Description

technical field [0001] The invention belongs to the technical field of heat exchanger design, and in particular relates to a design method of a special-shaped microchannel heat exchange tube, computer equipment and a storage medium. Background technique [0002] At present, there are few public reports on the tubular structure design of the air precooler in the field of aerospace propulsion. In the industry, regarding the structural design of special-shaped spiral tube heat exchangers, the length of the heat exchange tube and the heat exchange area of ​​the shell side are mainly designed for the heat exchange requirements. The specific design is mainly the pitch, curvature, and cross-section of the spiral tube. Shape, arrangement of heat exchange tubes (such as fork row or straight row), tube spacing, etc., lack of optimal design for heat exchange pipeline type. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention prov...
