A Liquid-cooled Pipe Network Layout Structure for Active Phased Array Antennas

Abstract

The invention relates to a liquid cooling pipe network arrangement structure of an active phased array antenna. The structure comprises a main inlet pipeline, the main inlet pipeline is divided into two paths which are horizontally symmetrical to each other, each path comprises an inlet detection component, an air heat exchanger, n TR module sets, antenna power supplies and an outlet detection component which are sequentially connected with one another, cooling liquid enters the main inlet pipeline and is divided into two paths horizontally symmetrical to each other, the cooling liquid of eachpath enters the air heat exchanger after subjected to the temperature, pressure and flow detection of the inlet detection component, and liquid-gas heat exchange is conducted once in the air heat exchanger; the cooling liquid heated by the TR module sets in a circulating mode is collected by a water collecting pipeline and enters the antenna power supplies, after the cooling liquid flows throughthe antenna power supplies of the left and right paths, the cooling liquid is collected to a main outlet pipeline after subjected to the temperature and pressure detection of the outlet detection component, and therefore the liquid cooling circulation of the cooling liquid is completed once in an antenna system; the liquid cooling pipe network arrangement structure can well achieve the good effects of uniform flow distribution and low pressure loss.

Description

Technical field [0001] The invention relates to the technical field of phased array radar antennas, in particular to an active phased array antenna liquid cooling pipe network arrangement structure. Background technique [0002] Liquid cooling pipelines have two connection modes: series and parallel. Usually, the series pipelines are used when the system or equipment requires large pressure, small flow and low temperature rise requirements; when the system or equipment requires large coolant flow , Use parallel pipelines when the pressure is small and the temperature rise requirements are strict. [0003] The active phased array antenna has a large number of TR components and antenna power modules, a compact space layout, and a large heat flow density. In the design of liquid-cooled pipelines, there is a prominent contradiction between pipeline flow distribution and pipeline pressure loss. If the parallel mode is adopted, the flow demand is large and the uniformity of the flow dis...

AI Technical Summary

Problems solved by technology

In the design of liquid cooling pipelines, there are prominent contradictions in pipeline flow distribution and pipeline pressure loss. If parallel connection is adopted, the flow demand will be large and flow distribution uniformity will be poor; if series connection is adopted, pressure loss will be superimposed, and the total system pressure will The demand is large and the cumulative temperature rise of the coolant is large; therefore, it is difficult to take into account the heat dissipation requirements of the system by using a single parallel or a single series pipeline
