Thermal Solutions for Power Electronics Cooling

In power electronics devices even small inefficiencies can result in large amounts of waste heat due to the large electrical currents and voltages that are transformed. Power electronics devices will exceed their safe operating temperature limits if the large amount of waste heat is not effectively dissipated.

Air and liquid cooling are the two heat sinking methods commonly practiced in industry. Although these two thermal management methods are straightforward in principle, there are a multitude of material and design options that can significantly impact cost and performance.

ACT designs and manufactures a broad range of power electronics cooling products.  ACT can provide cooling solutions from the device level to chassis level to the full cabinet – even rooms and shelters.  ACT has an entire spectrum of products to meet your power systems cooling needs.  ACT designs products for a range of applications from benign environment indoor test equipment to ruggedized off-shore motor controllers.  ACT understands the specific needs of the power electronics cooling industry and will design thermally optimized, cost effective solutions.

Systems such as automated manufacturing equipment rely on high power electronics to function. Thermal management is critical for safe operation.

ACT offers custom services for all your power electronics cooling needs

ACT is much more than a component provider.  We design, qualify, and manufacture the complete system.  Many thermal suppliers provide cold plates, fans, pumps, radiators, filters, and reservoirs.  Those suppliers do not have the interest or capability to provide a well-designed fully integrated thermal system.  ACT’s team of thermal, mechanical and electrical engineers provide a complete thermal solution, sized and priced for each customer’s unique requirements.  We use high-quality well-priced COTS components whenever possible and assure all components function together to provide a robust cost-effective system-level thermal solution.

ACT has in-depth thermal expertise in both air cooled heat pipe heat sinks and liquid cooled systems for power electronics thermal management. ACT also has several product lines and solutions to meet the needs of the power electronics industry. For air cooled heat sink solutions, ACT’s HiK™  plates, Vapor Chambers, and heat pipe assemblies are the perfect choice. For high powered electronics cooling, our passive loop thermosyhpons may be the most effective solutions.  For systems that require liquid cooling, ACT has custom cold plate fabrication capabilities and system level design expertise to meet any design requirement.

Simplify your life; don’t contact multiple vendors and piece together a high-priced solution yourself.  Contact the thermal experts at ACT – the one source for all your cooling needs.

When more advanced solutions are required, we have the expertise to  design, prototype, validate, and produce high performance high technology solutions.  Focus on your electronics – let ACT be your trusted thermal partner.
