An Aluminum Heat Sink and Radiator for Electrophoresis Capillaries

摘要

An aluminum heat sink and radiator are used with forced air cooling of an electrophoresis capillary. Theoretical analyses of the operating limits and heat dissipation characteristics are presented. A system designed for power dissipation as high as 5W is shown to dissipate heat efficiently and to operate without arcing at voltages higher than 30 kV.
