A Brief Introduction
to Liquid Cooling Systems
Thermal management of electronic components and systems is more
challenging than ever. Power densities continue to increase, while product form
factors continue to shrink. Engineers must now consider thermal management
early on in the product development cycle to make sure sufficient space
and power is available to remove heat from their system. Simple thermal
management solutions, such as a heat sink fan mechanism, are no longer viable
to keep critical systems operating at peak performance. In today’s complex
operating environment, liquid cooling systems are required to dissipate a
large amount of heat in a densely packed electronic environment. Maximum
operational life is required to keep system maintenance and repair down time
to a minimum. Temperature stabilization has especially become critical, as next
generation systems require more precise temperature control.
Liquid cooling systems (LCS) are self-contained units that recirculate a coolant
to a predefined temperature set point. There are two types of liquid cooling
solutions. The first is a liquid heat exchanger system that cools the coolant in a
liquid circuit to ambient temperature. This system consists of a pump to circulate
coolant, a liquid heat exchanger to dissipate heat, and a liquid circuit to transfer
coolant from the heat source to the LCS. The second type is a compressor-based
system, or recirculating chiller, that encompasses a compressor system instead
of a liquid heat exchanger assembly. It is used to cool the coolant to well below
ambient and dissipate heat to the outside environment. Additional features can
be included to add temperature control, variable flow control, bypass control,
coolant filtration and electronics in order to meet unique attribute requirements.
Compatibility of material selection to coolant is also critical in order to minimize
corrosion and keep loose oxidized particles from obstructing flow.
Customized Solutions
Since there are many unique attributes that need to be ascertained from each
application, often a liquid cooling solution requires a custom configuration to
optimize performance and long life operation. The type of coolant used will
depend on the desired control temperature. Laird has the know-how to design
cooling systems that are compatible with water, water-glycol, transformer oil
or various corrosion prohibitors. LCS can also be quite complex and require
temperature control of multiple liquid circuits or multiple pressure drop
settings in order to accommodate low and high pressure conditions. Laird has
experience with both and offers strong engineering design services with a
global presence that supports onsite concept generation, thermal modeling,
mechanical and electrical design and rapid prototyping. The company also
offers validation test services to meet unique compliance standards for each
industry, such as UL and MIL-STDs, or a unique standard specific to a medical,
industrial or semiconductor account.
Total Thermal Solution Provider
Due to the increasing complexities of thermal management systems, and the
constant pressure to reduce product development cycle times, companies are
relying on external, specialized thermal management expertise more often.
Laird has more than 35 years of experience in the design, manufacture and
servicing of liquid cooling systems for various high end markets. While Laird
focuses on designing the optimal liquid cooling solution, its customers are free
to focus on designing a better end instrument. All products are manufactured
in an ISO 9001 and ISO 14001 certified facility and are built to meet the
needs of strict process control requirements found in many of the medical,
industrial, and semiconductor industries. All parts are procured from strategic
suppliers with a proven track record of supplying highly reliable components,
and offer strong design support for customization. Laird also offers after sales
service support to repair or replace units that have been in the field for more
than two decades.
