Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, and the examples given are only for explaining the present invention, and are not intended to limit the scope of the present invention.

[0021] In phased array radar, TR components not only have a large number, but also generate a large amount of heat and are expensive. Therefore, thermal design of TR components is an important part of phased array radar antenna structure design. Currently commonly used cooling methods are: natural cooling, air cooling and liquid cooling. Liquid cooling technology is a very efficient passive thermal control technology. It uses liquid circulation to absorb the heat generated by TR components, and uses the coolant to bring the heat to an environment that is easy to dissipate heat, thereby cooling TR components and achieving extreme environmental protection. For the purpose of good temperature control of high-power ele...

Abstract

The invention relates to a liquid cooling device based on temperature uniformity design of high heat flow TR components, the liquid cooling device including two main cold plates and a plurality of branch cold plates located above the main cold plates. The main cold plates and the branch cold plates are internally provided with cavities for respectively forming main flow paths and branch flow paths. The branch flow paths are arranged in parallel and are respectively in communication with the two main flow paths. The branch flow paths are variable-diameter flow paths. A coolant enters from one main flow path, passes through each of the branch flow paths, cools TR components arranged at the surfaces on the branch flow paths and then flows out from the other main flow path. The liquid cooling device based on the temperature uniformity design of the high heat flow TR components according to the invention controls the shapes of the branch flow paths and the radial cross sectional size of each branch flow path so as to make the temperature of the liquid cooling device uniform at different positions.

Description

technical field [0001] The invention relates to a liquid cooling device, in particular to a liquid cooling device designed based on the temperature uniformity of high heat flow TR components. Background technique [0002] TR components have a high heat flux density and strict requirements on temperature uniformity. In the thermal design process, liquid cooling is generally used for high heat flux density. If the number of TR components is large, it is difficult for one channel to meet the heat dissipation requirements. Therefore, it is necessary to make full use of the coolant and connect multiple branch channels in parallel. However, the parallel multiple branches are located at different upstream and downstream of the main circuit, which may cause The problem of uneven traffic distribution. Both sides of each branch are connected to the main road, and the cooling effect is better than that of the middle part, which will also affect the temperature uniformity of different...
