Development and investigation of compact cooler using a pulsating heat pipe
Annotation
Results are given of development and investigations of a compact cooler for application in electronics, based on an open-loop oscillating heat pipe. The cooler operation is investigated, where water, methanol, and R141b Freon are used as working fluids under conditions of uniform and concentrated heat input. The effective operation of the device is demonstrated in the heat load range from $5$ to $250$ W. The “heat source-ambient air” minimal thermal resistance of $0.35$ $^\circ$C/W was reached with water under uniform heat load of $250$ W. The maximal value of heat load density is $75$ W/cm$^2$ with the heat flux concentration on the surface of $1$ cm$^2$, where methanol is used as working fluid.
