An Adaptive Growth Design Method for Heat Dissipation Network of Phased Array Radar T/R Components

Abstract

The invention relates to a self-adaptive growth design method for a phased array radar T / R assembly heat radiating flow passage network. The self-adaptive growth design method comprises the following steps of firstly, according to the heat radiation condition of assemblies, extracting a design domain of a heat radiation problem and a heat load boundary condition, and converting into the problem of plant root system growth relying on nutrition matter concentration in the design domain; enabling initial roots to grow, simulating growth iteration on the basis, and finally obtaining a design layout of a cold plate heat radiating flow passage network. The self-adaptive growth design method has the advantages that during design, the repeated design, simulation and improvement are not needed, the process of structural design of the conventional heat radiating network is broken through, and the design efficiency and quality are improved; because the layout optimizing design of the heat radiating flow passage network is performed by simulating the plant root growth relying on the nutrition matter concentration in soil, the nature of the flow passage network is more approximate in design principle, and a design result is more reasonable.

Description

technical field [0001] The invention relates to a liquid flow channel layout design method, in particular to an adaptive growth design method for a phased array radar T / R component cooling flow channel network. [0002] technical background [0003] The T / R component of the phased array radar sub-array is a large heat source with a high heat flux density. At the same time, it has high requirements on the environment. The temperature balance of the array element is better; the heat dissipation of high power density and high-power devices is usually realized by forced liquid cooling through forced liquid cooling cold plate and liquid cooling unit; The cooling effect directly affects the working temperature of the heating device; when the dimensions and installation position of the cold plate are determined, the structural design of the cooling channel network of the cold plate becomes the key. [0004] With the development of computer technology, the combination of cold plate ...

Problems solved by technology

Compared with the previous thermal experiment design method, this design method combined with thermal simulation saves a lot of cost and time, and can optimize the design more easily, but both require repeated design and simulation in the design process. , improved work, and the energy is mainly concentrated on the size optimization of the cooling channel network structure; and the layout configuration of the cooling channel network is usually linear, S-shaped or spiral, although the form is simple and easy to process manufacturing, but lacks the necessary theoretical basis, and does not necessarily match the actual heat generation situation, it is difficult to ensure the optimality of the heat dissipation network layout design
