Computer Cooling Pumps
Barber-Nichols, Inc. (BNI) has extensive experience designing pumps for a wide variety of applications.
Recent applications have been developed for liquid and two-phase cooling of high heat flux semi-conductor
devices. Microprocessor advancements have led to extremely high heat concentrations on the semi-conductor
material. Traditional forced air coolers and heat pipes can not provide satisfactory cooling for
next generation microprocessors without increased fan noise and large, cumbersome heat sinks.
BNI has developed several metal and plastic Computer Cooling Pumps that provide circulation for
advanced liquid cooling applications.
BNI has incorporated
design features into the pump which allow for the low-cost production of highly reliable pumps.
These pumps utilize brushless DC motors incorporated into the pump rotors which provide high-performance
and eliminate rotating seals which can wear and leak. Pumps have been designed to operate
in hermetic loops using water, ethylene glycol, propylene glycol, refrigerants, and even liquid
metal. Barber-Nichols has the abiltiy to design the pumping mechanism, electric motor, and control
circuitry for Computer Cooling Pumps which operate at sub-Watt power levels. These pumps and heat
exchangers can also be utilized by microwave transmitter/receiver components that require high
heat flux cooling solutions.
Barber-Nichols has the ability to provide high volume manufacturing of Computer Cooling Pumps and electric motors through our manufacturing partner based in Taiwan. With factories in Taiwan and China, our partner provides products for industry leading original equipment manufacturers such as Compaq, Dell, Hitachi, Samsung, and Siemens. Complete cooling solutions including the pump, heat-exchangers and fans can be engineered and supplied by Barber-Nichols.
