The invention relates to a bidirectional thermal siphon-valve operating by natural convection. It further relates to an installation for the production and storage of heat or cold comprising such a thermal siphon-valve, preferably with a continuously operating pump. The thermal siphon-valve functions to direct a heat-transfer fluid toward one of two hydraulic circuits, or to divide it between the two circuits, on the basis of its temperature. It is distinguished by the fact that it comprises an entirely internally open tubular body (14) with a vertical axis which is provided with at least one inlet orifice (10a) for the heat-transfer fluid, located substantially in its middle portion, and two outlet orifices (10b, 10c) for the heat-transfer fluid, located in its lower and upper portions, respectively.

Installation for the production and storage of heat recovered at an outlet of a heat-producing source that produces heat intermittently comprising a thermal siphon-valve, for directing the flow of a heat transfer liquid, formed of a tubular hollow body having a vertically oriented axis, at least one inlet orifice located along the axial length of said body, and upper and lower outlet orifices located respectively in upper and lower end portions of said tubular body with said inlet orifice therebetween and with all of said orifices being in continuous physically open communication with one another; a storage tank located to have a hydrostatic head at a higher elevation than said thermal siphon-valve; a source circuit including an inward-flow conduit coupled from said source to the inlet orifice of said tubular body and a return-flow conduit coupled from said source to the lower outlet orifice of said tubular body; a tank circuit comprising an inlet conduit coupled to said storage tank from the upper outlet orifice of said tubular body, and an outlet conduit coupled from said storage tank to the return-flow conduit of said source conduit; and pumping means in said source circuit for pumping the heat transfer liquid in said source circuit between said source and said thermal siphon-valve.
