Liquid Cooling Subsystems
ETM has developed a line of liquid cooling subsystems ranging in capacity from 3 kW to over 200 kW, providing coolant flow from 3 GPM to 60 GPM (10 liters per minute to 230 liters per minute). Heat removal is accomplished with liquid cooling mediums such as low conductivity deionized (DI) water, Coolanol, PAO, and Glycol mixtures. In addition to the basic job of removing heat from high-power electronics, ETM's heat exchangers are tailored to meet additional requirements driven by the customers' applications, such as:
- Closed-loop coolant temperature control
- Redundancy and on-line repair
- Nitrogen blanketing
- Active control of resistivity
- Pump speed control to set outlet pressure
- Packaging for outdoor or mobile use
- Extended operating temperature ranges
- Full-flow filtration
- Coolant preheating
- Precision temperature and flow monitoring
- Economizer coils to eliminate dependence on mechanical refrigeration in cool weather
ETM liquid cooling subsystems use the following technologies:
Liquid-to-air
Liquid-to-liquid
