wherein said discharge operation is allowed in correspondence of a detection of said flow rate value at least equal to a reference threshold value and wherein said discharge operation is inhibited in correspondence of a detection of said flow rate value that is null or lower than said reference threshold value.

THERMAL ENERGY STORAGE APPARATUS

Climate Change Technologi...


1. A thermal energy storage apparatus, including:a block of a heat-absorbing material, the block defining at least one receptacle and being a contiguous block of compressed sintered graphite; and
a phase change material stored in the or each receptacle, the phase change material being one that expands as it cools,
wherein separation of side walls of the or each receptacle progressively increases as the side walls extend upwardly from a base of the or each receptacle, whereby as the phase change material solidifies and expands it is urged upwardly to reduce pressure applied to the heat-absorbing material, and wherein the side walls are formed with a progressively decreasing wall angle as the side walls extend upwardly from the base.

METHOD FOR HEAT EXCHANGE AND CONDITIONING OF A HEAT EXCHANGER

Hutchinson, Paris (FR)


1. A method for thermal exchange, wherein:a) at a first moment in time, in a thermal energy storing device, at least part of a thermal energy previously accumulated in a form of calories is discharged to an oil, to heat said oil by thermal exchange,
b) subsequently, at a second later moment in time, when said oil has, during step a), been heated to a temperature higher than a temperature of a water, said water receiving thermal energy by thermal exchange, through a first wall of the thermal energy storing device, said oil which then circulates on an other side of a first wall that prevents said oil and said water from mixing,
the thermal energy storing device comprising at least one phase-change material, which, at said first point in time, stores at least part of a thermal energy previously accumulated in the form of calories which is discharged to said oil, said thermal energy previously accumulated having been stored during a previous operation of an engine, during a previous thermal exchange with said oil which was, when the previous thermal exchange took place, at a temperature higher than the change-of-state temperature of said at least one phase-change materials, said method being implemented, on a vehicle equipped with a crankshaft and cylinders, and/or a gearbox, arranged in said engine, at an intersection a first oil circuit of the vehicle in which said oil is allowed to circulate and a second water circuit of the vehicle in which said water is allowed to circulate, the first oil circuit passing in the gearbox and/or in contact with the crankshaft and the cylinders.
