Capillary-pumping heat-transport device
First Claim
1. A capillary-driven heat transfer device under an influence of gravity, adapted to extract heat from a heat source and to release this heat to a cold source by means of a two-phase working fluid contained in a closed general circuit, comprising:
- an evaporator, having an inlet and an outlet, and a microporous mass adapted to perform capillary pumping of fluid in the liquid phase,a condenser, having an inlet and an outlet,a reservoir having an inner chamber, and at least one inlet and/or outlet port, the inner chamber having a vapor phase portion located on top of a liquid phase portion,a first communication circuit, for fluid mainly in a vapor phase, connecting the outlet of the evaporator to the inlet of the condenser,a second communication circuit, for fluid mainly in a liquid phase, connecting the outlet of the condenser to the reservoir and to the inlet of the evaporator, wherein the reservoir includes plural separate volumes of the liquid phase, said separate volumes remaining in fluid communication, the reservoir including a plurality of inner partitions forming compartments adapted to separate said plural separate volumes of the liquid phase, andsmall cross-sectional passages, said plural separate volumes communicating through the small cross-sectional passages, in order to create hydraulic damping between the separate volumes of the liquid phase.

Abstract
A capillary-driven heat transfer device, adapted to extract heat from a heat source and to release this heat to a cold source by means of a two-phase working fluid, includes an evaporator, having a microporous mass adapted to perform capillary pumping of fluid in the liquid phase, a condenser, a reservoir having an inlet and/or outlet port, a vapor communication circuit, connecting the outlet of the evaporator to the inlet of the condenser, and a liquid communication circuit connecting the outlet of the condenser to the reservoir and to the inlet of the evaporator. The reservoir includes multiple separate volumes that remain in fluid communication.
