Problems solved by technology

However, when the thermal power consumption of the T / R components increases and the liquid-cooled cold plate heat dissipation technology with higher heat exchange efficiency is required, the middle partition will not have enough space for ventilation holes, and it will be separated from the middle partition. The cold plate installed vertically will cause greater resistance to the bottom air intake, which is not conducive to the successful realization of this scheme

Abstract

The invention provides a loop control system design method and a frame structure of an active phased array radar antenna, which can effectively solve the problem of thermal control of low-power components that are distributed dispersedly, such as a unit controller, a high-frequency receiver, a power distribution network and the like in an active phased array radar antenna except T / R components anda power supply thereof, and generally realizes the technical means of air cooling and liquid cooling mixed heat dissipation of an active phased array antenna. Compared with the prior art, the schemeof the invention has the following advantages: 1, the problem of heat dissipation of the low-power components such as the unit controller, the high-frequency receiver, the T components, the power distribution network and the like in the active phased array radar antenna can be solved, and the scheme can be matched with a liquid cooling cold plate aiming at the T / R components and the power supply to realize the technical means of air cooling and liquid cooling mixed heat dissipation of an active phased array radar antenna system; 2, an air supply channel and an air return channel are both basedon a middle sandwich structure of a side beam of an antenna frame, the process of specially designing a static pressure cavity is not required, the size of the antenna can be reduced, and the integration of the structure and a heat dissipation function can be achieved; and 3, the fluid flow direction is generally parallel to the installation direction of the cold plate and power consumption components, and thus the flow resistance can be reduced, and the power consumption requirements of a fan and the power supply can be reduced.

Description

technical field [0001] The invention relates to the field of antenna thermal design, in particular to an active phased array antenna-oriented environment control system design method and a frame structure, which are used to guide the heat dissipation design of the active phased array antenna. Background technique [0002] With the rapid development of electronic technology and the continuous improvement of military equipment requirements, the integration of active phased array antennas is getting higher and higher, and the heat flux density in the system is also increasing, and the heat generation of some chips has exceeded 100W / cm 2 , the U.S. Navy predicts that the heat flux density of T / R components in the future may exceed 1000W / cm 2 . If such high heat cannot be dissipated in a timely and effective manner, the working performance of the radar system will be seriously affected. The specific manifestations are: high temperature causes thermal deformation of the structure...
