High-efficiency passive cooling solutions for power electronics
Power electronics applications in sectors such as energy and electric mobility demand ever-increasing power concentrations, which translates into higher thermal demands and the need for more efficient cooling systems.
In many cases, companies opt for active (liquid) cooling solutions too early, increasing power consumption and reducing system reliability.
At ALAZ ARIMA, we are committed to a different approach: the development of high-performance passive cooling solutions.
Passive cooling without pumping: Efficiency, Reliability and Sustainability
At ALAZ ARIMA, we design highly efficient passive (pump-free) cooling systems for power electronics (IGBTs, thyristors, converters, inverters, etc.).
Our solutions are based on the phase change of a fluid, which allows for optimal heat transfer without the need for active components, electricity consumption, or maintenance.
This technology enables us to offer efficient, reliable, and sustainable cooling systems, ideal for environments where thermal stability and durability are critical.
Advantages of our passive cooling solutions
The passive cooling systems developed by ALAZ ARIMA provide key benefits to equipment such as photovoltaic inverters, traction converters, converters or electric vehicle chargers:
Greater reliability
Unlike water-cooling solutions, our systems don’t require pumps, expansion tanks, or valves, eliminating components prone to failure.
Fewer moving parts = Greater reliability and system lifespan.
Lower consumption and carbon footprint
Since no energy is required for pumping, electricity consumption is significantly reduced, improving energy efficiency and decreasing the system’s carbon footprint.
Higher operating temperature
Passive systems allow operation at higher temperatures without degrading performance, reducing or eliminating deratings and decreasing the number of inverters needed per plant to comply with current grid codes.
High dynamics in cooling
The dynamic thermal behavior of our solutions prevents temperature spikes that could fatigue semiconductors in the long-term, improving thermal stability.
Elimination of condensation
Our systems behave like thermal diodes, preventing undesirables condensations and protecting electronic components in changing environments.
