Description

Distributed micro-regional intelligent thermal control system Technical Field The invention relates to the technical field of phased array radars, in particular to a distributed micro-area intelligent thermal control system. Background Phased array systems of current high performance, miniaturized, integrated design are increasingly being used. The high density of integrated design brings advantages of miniaturization, light weight and low cost, and simultaneously, the high requirements on the thermal control of the system are also made. Conventional heat sinks typically treat the entire device or chamber as a uniform heat source, with the aim of reducing the overall temperature and homogenizing the heat dissipation. However, in a practical phased array system, the heat consumption is dynamically changed, and the hot spot position and intensity are also rapidly changed, which can cause higher challenge to heat control. The traditional phased array heat radiation structure mainly comprises a combination of a fan and a metal conducting surface, has wide air flow coverage range, can not concentrate cooling capacity on one or more specific hot spots like liquid cooling or micro-area heat control, and can not generate specific optimized influence on heat radiation of a high-heat element. The design can meet the daily or conventional scene application, has no solution to the scene of large-scale, miniaturized and integrated non-uniform heat source distribution, or needs huge size and power consumption to solve the problem, and does not meet the thermal control development requirements of current miniaturization, refinement and low power consumption. The traditional centralized heat control needs to cover the whole system, so that in order to meet the local high heat dissipation requirement, the whole heat dissipation power is often required to be excessively improved, for example, the rotation speed of a fan is increased, the water cooling flow is increased, and various problems of overlarge energy consumption, low heat dissipation efficiency and the like are caused.
