Vacuum-based thermal management system

Abstract

A thermal management system and method are presented for cooling an entity. The system comprises: a closed loop fluid flow line for flow of a coolant while being transferred in between its liquid andgas phases; at least one cooling zone located within the flow line and comprising at least one cooling interface; a vacuum generator unit operable for creating and maintaining vacuum condition at thecooling zone to thereby reduce evaporation temperature of the coolant located in the cooling zone; and a condensation zone spaced apart from the cooling interface downstream thereof with respect to adirection of the coolant flow from the cooling zone along the closed loop path wherein the coolant is condensed to liquid phase.

Description

technical field [0001] The present disclosure relates to thermal management systems, and more particularly to vacuum-based cooling systems. Background technique [0002] One of the major problems in electronics is the increase in heat generation as computing performance increases. The ever-increasing trend to improve cooling of microprocessor and amplifier-based systems, such as those contained in telecommunications cabinets and cloud computing centers, is becoming increasingly critical to the electronics industry. Finding an effective thermal solution is therefore the three dominant factors between the success or failure of commercial electronics development and sales—reducing system cost, time-to-market, and performance as major constraints. [0003] The industry trend of system miniaturization (one of the electronics industry's main methods to meet the growing market demand for faster, smaller, lighter and cheaper electronic devices) further exacerbates the problems caus...
