Liquid Cooling and Two Phase Cooling: A Case Study to Examine the Tradeoffs for a “Best” Solution

Electronics Cooling has published a study by Anurag Gupta, David H. Altman and Stephen J. Pereira to demonstrate the trade-offs between liquid and two-phase cooling schemes for small-channel heat sinks in high heat flux applications.

The study is a fascinating examination of the topic and has some interesting results that are worth noting. Applications for liquid cooling are growing and understand the tradeoffs in different approaches is a critical element in determining an engineers best options.

maxiFLOW™ extended linear heat sinks reduce the intensity of heat generated by high output LEDs

A series of maxiFLOW™ heat sinks are available from ATS for cooling OSRAM DRAGONstick LEDs and other linear LED lighting products. The heat sinks feature a low profile, spread fin array that maximizes surface area for more effective convection (air) cooling, particularly when airflow is limited. The sinks are fabricated from extruded aluminum which enhances their bottom to top heat transfer properties, while minimizing their weight and cost.

The Fundamentals of Magnetofluiddynamic Pumps: How Liquid Metal Can be used to cool your electronics

The use of liquid metals as a cooling method is on the peripherery of high performance electronics thermal management. The thermal conductivity of liquid metals can be orders of magnitude greater than water, glycol, or engineered dielectric fluids.

This means an equivilent amount of cooling can be performed using much less mass flow rate. The requirements for pumping and pressure heads are reduced, which can in turn increase reliability.
