Abstract

The invention discloses a parallel flow channel cooling system optimization method based on a field cooperation equation. The method includes: giving an initial parallel flow channel cooling system with flow channel width distribution, solving a momentum equation and an energy equation to obtain a system velocity field and a temperature field, and recording the average temperature (Ts) of each heat source boundary; setting heat source boundaries as isothermal boundaries, setting a temperature value as the recorded average temperature Ts of the heat source boundaries, and calculating a convective heat transfer field cooperation equation to obtain a speed field of the parallel flow channel cooling system; using the obtained velocity field to recalculate the energy equation to obtain the average temperature Ts'of each heat source boundary, taking the Ts' as a heat source boundary to recalculate the field cooperation equation, and repeating the process until the component residual error of the Ts' and the Ts is smaller than the set convergence residual error; and then based on the flow channel speed distribution of the system at the moment, solving a flow resistance network reverse calculation model to obtain optimized structure parameters of the system. The method has the advantages of being free of experiences and randomness, short in optimization time, good in optimization effect, high in applicability and the like.

Description

technical field [0001] The invention relates to the field of cooling system optimization, in particular to a method for optimizing a parallel channel cooling system based on field coordination equations. Background technique [0002] With the continuous development of science and technology, the volume of various electronic equipment is getting smaller and smaller, and the heat generated by electronic equipment during work is not easy to discharge, and the heat accumulation will greatly increase the temperature, which will seriously affect the safety and security of electronic equipment. life. [0003] Therefore, it is necessary to design an efficient cooling system for electronic equipment to ensure that the heat generated by it is taken away in time, thereby prolonging the life of electronic equipment. [0004] The cooling system is generally divided into a serial channel cooling system and a parallel channel cooling system. [0005] Compared with the serial channel cool...
