Liquid Cooling Systems from Laird Efficiently Cool Industrial X-Ray Scanners


Laird’s liquid cooling systems effectively and economically dissipate large amounts of heat generated by industrial x-ray systems…

February 8, 2018 – Laird Thermal Systems designs custom, self-contained liquid cooling systems that provide precise temperature control in industrial x-ray scanning equipment. Industrial x-ray scanning equipment is used in a wide variety of applications ranging from non-destructive test for materials/manufacturing defects and contaminants to scanning trucks or baggage to ensure safety and security. Liquid cooling systems offer higher efficiencies compared to air‐based heat transfer mechanisms, which translates into higher reliability, reduced field maintenance, greater system uptime and lower total cost of ownership.

X-ray inspection can be used for both process and quality control in automated assembly lines. Only a small portion of the energy generated by these systems is emitted as X-rays; the balance is released as heat. Industrial X-ray systems, which can generate several kilowatts of heat during operation, require cooling of the anode to dissipate this heat for optimized performance and a longer operating life.

Offering optimal temperature stabilization and precise temperature control, liquid cooling systems recirculate coolant to a predefined set-point temperature. Laird’s liquid cooling systems offer many advantages over conventional air-cooled systems by providing higher heat pumping capacity, better ability to direct the heat away from the X-ray tube, more rapid cool down time, and lower noise operation. In addition, liquid cooling systems are more reliable and requires less maintenance.

Depending on the industrial scanner’s application, three different types of liquid cooling systems can be utilized. Laird offers a wide range of standard and custom liquid cooling systems comprised of liquid-toair, liquid-to-liquid, or chiller-based systems. Liquid cooling systems feature precise temperature control, variable coolant flow rate, coolants with corrosion inhibitors and coolant filtration, as needed. Liquid cooling systems are available in various sizes and cooling capacities to meet most any industrial x-ray application requirement.

“Customers expect an liquid cooling system lifespan that equals that of the scanner,” said Greg Ducharme, Product Director at Laird Thermal Systems. “If an x-ray system goes down, it can shut down the entire manufacturing, inspection or security check process. This can significantly impact production and incur large manufacturing costs, or back-up security screening causing massive delays. An liquid cooling system should combine ruggedness, reliability and high performance with cost efficiency and must be easy to service in order to minimize system downtime and maintenance costs.”
