A capillary-driven heat transfer device is adapted to extract heat from a heat source and release this heat to a cold source using a two-phase working fluid. The device includes an evaporator having a microporous mass performing capillary pumping of fluid in the liquid phase, a condenser, a reservoir having an inner chamber and an inlet and/or outlet port, a vapor communication circuit, connecting the outlet of the evaporator to the inlet of the condenser, a liquid communication circuit, and a non-return device arranged between the inner chamber of the reservoir and the microporous mass of the evaporator, and arranged to prevent liquid present in the evaporator from moving to the inner chamber of the reservoir. |

1. 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 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, a first communication circuit for fluid mainly in the vapor phase, connecting the outlet of the evaporator to the inlet of the condenser, a second communication circuit for fluid mainly in the liquid phase, connecting the outlet of the condenser to the reservoir and to the inlet of the evaporator, a non-return device arranged between the inner chamber of the reservoir and the microporous mass of the evaporator, and arranged to prevent liquid present in the evaporator from moving back to the inner chamber of the reservoir, the device being mainly under the influence of gravity, the non-return device including a float returned by buoyancy thrust to a seat in the closed state. |
