- Liquid Cooling
When convection / air cooling isn’t able to remove the heat load required to keep electronics under their safe maximum operating temperature, single-phase liquid cooling solutions offer a high level of performance. Liquid-cooled, cold plates are commonly used for high-heat flux or high-power electronics cooling applications.
System Level Approach
Liquid cooling can be very advantageous when done properly. Much of the challenge is the lack of single-source expertise to develop complete solutions. In many cases, prime integrators work with chiller suppliers, pump suppliers, accumulator suppliers and handle packaging and balance of plant on their own. This method has shown strong results but will often times lead companies with a more complex design than is necessary as each component is adding margin and contingency to the design parameters. ACT is a leader in system level liquid cooling design, with expertise in all aspects. With dedicated specialists that discretely handle detailed liquid loop thermal analysis, chiller design, cold plate or liquid heat exchange design and balance of plant engineering all working together, optimized designs can be achieved in a fraction of the time. ACT has also developed a large supply chain and expertise in integrating and ruggedizing systems for specific requirements.
Sub-System / Component Level Engineering
ACT offers a variety of custom thermal solutions to optimize the performance of existing liquid cooling loops. Whether you need to improve cold plate performance, require pump selection, or need support with the fluid control aspects we are here to help.
Liquid Cooled Chassis
When power requirements reach a certain level, liquid-cooled chassis become a thermal management option. This method pumps liquid directly through cold plates that are in contact with the electronics boards. Direct liquid cooling provides the highest performance due to its high heat transfer coefficient but adds system-level risk.
Accumulators
Accumulators in spacecraft thermal control systems play a crucial role in managing and regulating the temperature of various components on the spacecraft. These systems are designed to handle the extreme temperature variations that spacecraft may experience in space, where they can be exposed to both intense solar radiation and cold darkness.
