<p>A capillary device (102) for use in a heat pipe in which heat is transferred from at least one evaporation region to at least one condensation region by means of evaporated working fluid is disclosed. The capillary device comprises a body portion defining chambers (108) containing powdered material (110) therein, wherein at least part of the periphery of at least one said chamber is porous to allow flow of condensed working fluid, by means of capillary action, through said powdered material in said chamber when flowing from a condensation region to an evaporation region.</p> |
