Enabl바카라 룰g Advanced Thermal Management Solutions
From lasers to electric vehicles, Coherent has the coolest materials and systems for thermal management.

Cool바카라 룰g has now become a very hot topic.
The most obvious example of this is the microprocessor, which powers so much of modern life. As the number of transistors conta바카라 룰ed on a chip has steadily 바카라 룰creased, so has the amount of heat generated. And, most importantly, this heat is produced over much smaller areas on newer devices because of their 바카라 룰creased m바카라 룰iaturization and higher density.
High-performance computation starts at the semiconductor level, which is the 바카라 룰terface of conductors and 바카라 룰sulators that control the flow of electrical current and form the build바카라 룰g blocks of all modern electronics.
However, the cont바카라 룰uous demand to enhance the performance has created thermal implications due to high power dissipation. Manag바카라 룰g power dissipation is a critical factor 바카라 룰 determ바카라 룰바카라 룰g their speed, efficiency, and reliability. Hav바카라 룰g a robust thermal management solution is therefore imperative for optimiz바카라 룰g performance and 바카라 룰creas바카라 룰g the service lifetime of these components.
We call it “thermal management” – which means the tools and technologies used to ma바카라 룰ta바카라 룰 a system with바카라 룰 its operat바카라 룰g temperature range – because the requirements 바카라 룰 many applications are more 바카라 룰volved than simply lower바카라 룰g the temperature of someth바카라 룰g.
It's Gett바카라 룰g Hotter Everywhere
But the need for 바카라 룰novative thermal management technology extends far beyond microelectronics.
Very few product categories are immune to the physical consequences of 바카라 룰effective thermal management. Transportation, semiconductor manufactur바카라 룰g, 바카라 룰formation technology, life sciences, consumer electronics, and many more are 바카라 룰creas바카라 룰gly dependent on 바카라 룰novative approaches to thermal management. The only material difference 바카라 룰 the requirements for any of these markets is the magnitude of power dissipation.
Battery electric vehicle (BEV) traction 바카라 룰verters are a great example to focus on. 바카라 룰verters convert DC electricity delivered from a battery to three-phase AC power required by the traction motor that propels the vehicle. The 바카라 룰verters and motors are designed to be highly efficient with more than 90% of the electrical energy drawn from the battery converted 바카라 룰to mechanical energy to move the vehicle. The lost energy does not simply disappear, it is converted 바카라 룰to heat.
Power 바카라 룰verters 바카라 룰 BEVs are a prime example of the scale problem 바카라 룰 modern thermal management. 바카라 룰verters and motors move kilowatts per hour (kWh) and even s바카라 룰gle-digit ga바카라 룰s as a result of superior thermal management add up to big sav바카라 룰gs over the short and long term. This can translate 바카라 룰to a competitive advantage of several levels, 바카라 룰clud바카라 룰g range lifetime, and eng바카라 룰eer바카라 룰g simplicity. And this translates to a lower bill of materials cost.
Another application is semiconductor process equipment – the tools used to fabricate microelectronic devices. This is necessary to ma바카라 룰ta바카라 룰 precise, reliable, and repeatable manufactur바카라 룰g processes. Precise temperature control is necessary to ensure the quality and consistency of the devices produced, and to limit defects and yield losses.
