NEW SOLUTIONS

IN THERMAL MANAGEMENT THROUGH ULTRAFAST LASER SURFACE STRUCTURING

Quantum Qool is an innovative startup where its patented ultrafast laser surface structuring technology was developed by Chairman, Co-Founder  & CTO Victor A. Rivas. The World Intellectual Property Organization approved all 13 claims of the technology in 2014 as being industrially applicable, novel, and inventive.

This laser functionalized surface technology is integrated into an ultrashort pulse laser multi-beam manufacturing unit, the Q2 Laser Station, to enhance the surface area volume/ratio of materials and their effectiveness in emitting thermal radiation (i.e. emissivity), which significantly improves power and heat management by factors of 10 times or more.

Fundamentally, the technology enhances the capabilities of materials & alloys such as copper, aluminum, nickel, graphite & silicon carbide with relevant micro- and nanostructures for multiple space, defense and power electronic applications.

The Q2 provides leading edge femtosecond laser performance with industrial reliability and integrated diffractive optics, which significantly boosts production throughput never seen before commercially. Ultrashort pulse “cold processing” lasers produce negligible residual heat effects and, thereby, prove ideal for precision processes that were, until recently, unachievable.

OTHER LASER PROCESSES

When materials are laser machined, their electrons become excited and radiate the excess energy before coming back to a resting state. The time in-between can last anywhere from a few microseconds to a couple nanoseconds.

Using microsecond or nanosecond laser processing (long pulse) means broader intensity and more thermal diffusion. This leads to large, uneven valleys in the surface and the formation of heat-affected zones. The heat-affected zones typically lead to microcracks, which lend to substantial mechanical and durability failures.

QUANTUM QOOL

Using our patented femtosecond (one quadrillionth of second) laser machining process, the pulse duration is so short that the excited electrons don’t have enough time to come back to a resting state before the processing is done, which leads to high penetration depth, less thermal diffusion, and faster fabrication speed for creating nanostructures for desired functionalities. This includes greater surface areas, more energy capacity and faster heat dissipation.

A DEEPER LOOK AT OUR RESULTS

A scanning electron microscope (SEM) image of this nickel material before & after ultrafast laser surface structuring displays the substantial increase in surface area and ultimately emissivity via micro- and nanostructures.

These engineered structures can complement, augment and possibly eliminate conventional conduction & convection cooling flows with enhanced heat dissipation.

Infrared imaging shows a brighter, machined microprocessor after ULSS, where the temperature is 10 degrees hotter, as it’s emitting more thermal radiation AWAY from the microchip enclosure.

This means optimized heat transfer, so the microchip can handle more heat at higher temperatures within the enclosure consistently in extreme environments.

ULSS at Industrial Scale

  • Laser-structure matter without generating heat on novel materials and products from metals, ceramics, and complex polymers

  • Eliminate time consuming pre- & post-processing steps, reducing critical thermal surface treatment steps from weeks to hours.

  • Eliminate chemical processes that create environmental problems during the machining process and minimize your waste stream

We can provide a customized thermal management solution for your components in extreme temperature environments.
