Space-Based Distributed Cooling System

ABSTRACT: Due to the high cost and long lead time of space based thermal management systems, there is an increased need for a space qualified thermal network system which can maintain critical components within an acceptable range during operation. SA Photonics has developed the baseline design of their Intelligent Thermal Stabilizing System, which is a compact, modular system which can efficiently network thermal energy within an electronic sub-assembly. Our ITSS configuration allows for low power networking of the thermal energy as well as zone maintained temperature control. The ITSS system uses solid state thermal devices in a unique configuration and control system for improved system performance. Our microvalve design operates in parallel with the solid state devices for low power pseudopassive thermal networking. The SA Photonics ITSS system combines complimentary thermal control systems in a compact package for efficient package level thermal networking high power density hotspot temperature control BENEFIT: The main benefit of the SA Photonics ITSS system is the ability to monitor and control critical components within acceptable temperature ranges by the control of heat flow (thermal networking). The compact ITSS design will thermally network components and heat sinks together within electronic sub-assemblies maintaining temperature control through the directing of heat flow into and out of components and heat sinks using our microvalve (pseudopassive) and solid state thermal control components. The combination of our microvalve design and unique configuration of active thermal control components efficiently manages high density power and significantly reduces thermal hot spots
