Liquid cooling systems using cylinder actuator for high-performance computing systems

Abstract

Embodiments presented herein include systems and methods for cooling a device, such as a computing system for an autonomous vehicle. In one or more embodiments, a linear drive actuator may be employed to circulate cooling fluid (or coolant) to the computing system. Unlike typical hydraulic or linear actuators, embodiments herein are capable of consistent directional circulation of the fluid while the actuator is moving in both forward and backward directions. Using a linear actuator not only uses fewer parts as compared to current cooling systems, but such embodiments have additional benefits. A linear actuator cooling system can use a smaller motor than traditional pump cooling systems, has more control relative to rate and pressure, produces less noise, produces fewer vibrations, and has a longer lifespan. Embodiments may also be configured to facilitate circulation of the coolant even in the event of a controller or motor actuator malfunction.
