ACT’s thermal engineering experts have helped guide clients in the military, telecommunications, medical equipment, manufacturing and aerospace industries to a variety of effective and cost effective thermal solutions. Using our extensive product development and manufacturing experience, we offer feasibility studies to generate and evaluate potential thermal management solutions from many important aspects including: cost, performance, manufacturability and reliability. We can help you save time and avoid costly delays at the end of your project by identifying the correct thermal solution up front. We can do a trade study to determine which of multiple potential thermal solutions offers the best performance and value.


ACT has a staff of thermal engineers who are fully competent in both CFD (Computational Fluid Dynamics) and heat transfer analysis. Our thermal engineers are fluent in commercial software packages and can also create or modify computational codes as required. ACT’s thermal engineering professionals have simulated thermal phenomenon at all lengths and scales including the atomic (Ab Initio, Molecular Dynamics), microscopic (Boltzmann Transport Equation, Phase Field Modeling) and macroscopic (CFD, FEA). ACT also develops custom codes for analyses involving multiple phases and components, including: heat pipes, heat sinks, vapor chambers two phase boiling flows, thermal storage using Phase Change Materials and chemical reaction mechanisms. Whether it’s a simple heat sink extrusion or a high heat flux pumped two phase loop, our engineers can design and specify a solution that is appropriate for your project and budget.


Along with our in-house volume manufacturing, we offer custom thermal management component and system prototyping. We offer high quality, fast turnaround on heat pipes, vapor chambers, as well as full solutions including integration with Thermoelectric coolers, power electronics laser devices, etc. Along with passive thermal solutions such as heat pipes and phase change materials, ACT also builds thermal storage devices, pumped liquid and two phase systems.


ACT has in-house volume manufacturing operations that are certified under ISO9001:2008 and AS 9100 C quality standards. We have a heat pipe manufacturing line that produces >250,000 heat pipes annually which are then integrated into a variety thermal management devices for military, aerospace, and commercial applications.
