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

Abstract

The invention discloses a special-shaped micro-channel heat exchange tube type design method, computer equipment and a storage medium. Heat exchange tubes arranged in a cylindrical heat exchanger are Archimedes spiral type heat exchange tubes, the minimum air circulation area ratio in the section of the heat exchanger is set, and the outer diameter of the heat exchanger, the wall thickness of a single heat exchange tube and the inner diameter of the tube are given; the arc length and the heat exchange area of a single heat exchange tube are determined; basic variables are selected, and a search area of each basic variable is determined; according to the inner diameter of the heat exchanger and the wall thickness and the pipe inner diameter of a single heat exchange pipe, the number of heat exchange pipes capable of being arranged in the heat exchanger is determined, and the total heat exchange area of the heat exchanger is the total heat exchange area of all the heat exchange pipes; and in the search area, an optimization scheme that the actual air circulation area ratio meets the set condition and the maximum total heat exchange area of the heat exchanger can be obtained is searched. The tube type, the layout and the number of the single heat exchange tube with the largest heat exchange area can be obtained only by knowing several basic parameters of the heat exchanger, and the tube type design premise is provided for 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...
