Abstract
A cooling device using a capillary pumped loop (CPL), including a lower board having a looped groove formed on the upper surface, an upper board combined with the upper surface of the lower board to cover the groove, so that the flow path of a working fluid is provided, an evaporator which is provided on the flow path, and has a plurality of fine evaporating fins incorporated into the upper or lower board, and a condenser which is provided on the flow path at a predetermined distance apart from the evaporator, and has a plurality of fine condensing fins incorporated into the upper or lower board. Accordingly, a thin and small cooling device capable of performing cooling without external power can be obtained. Also, various modifications of a simple micro channel attached to an evaporator eliminate a resistance on a flow path produced by an increase in the specific volume of a working fluid due to the phase change of the working fluid, and prevent a backward flow of the working fluid due to a rapid increase in pressure. Therefore, the entire cooling system can have hydrodynamic instability.
