Airborne phased array antenna phase change heat storage liquid cooling heat dissipation box

Abstract

The invention discloses an airborne phased array antenna phase change heat storage liquid cooling heat dissipation box, which aims to provide a phased array antenna box body with fast heat dissipation, good effect and high heat dissipation efficiency and combining liquid cooling heat dissipation and phase change heat storage. The heat dissipation box is realized through the following technical scheme: the bottom of a box body (1) is a heat dissipation base (3), the upper layer of the heat dissipation base (3) is a liquid cooling layer (4), and the lower layer is a phase change material layer (5); the liquid cooling layer is provided with an S-shaped liquid cooling flow channel, a liquid cooling inlet and a liquid cooling outlet; the phase change material layer is provided with a pluralityof honeycomb-shaped partition frame cavities enclosed between a liquid cooling layer partition plate and a box body bottom plate; the liquid cooling flow channel transfers heat out by theflow of the liquid cooling coolant; and the phase change material layer transfers heat generated by the phased array antenna to the phase change material stored in the phase change material layer by utilizing a metal partition frame connected between the partition frame cavities. The invention solves the problem that the antenna heat of the phased array antenna cannot be exported in time due to the interruption of the liquid supply under a short-time emergency condition.

Description

technical field [0001] The invention relates to an active phased array antenna mainly used in the fields of aerospace communication, navigation and the like, in particular to a phased array antenna box combining liquid cooling and heat dissipation with phase change heat storage. Background technique [0002] The active phased array antenna is light in weight and small in size. There are many electronic modules in the antenna, feeder, T / R, power supply, cooling and other systems installed inside the antenna. In actual work, most electronic components have strict requirements on high-temperature environments, and the ambient temperature is not allowed to exceed or approach the limit they can withstand, otherwise the proper electrical performance indicators will not be achieved, and even damage will occur. The thermal power consumption of the active phased array antenna is mainly concentrated on the T / R components, and the antenna array may have thousands of T / R components and ...
