Abstract: Heat transfer device including: a first reservoir (R1) for storing a diphasic fluid (LC), equipped with first heating means (MC1) and connected to a cold source (SF) via a first thermal resistance (RTH1); a second reservoir (R2) for storing said diphasic fluid, equipped with second heating means (MC2) and connected to said cold source or to another cold source via a second thermal resistance (RTH2); and a fluidic pipe (CF) through which said diphasic fluid may pass, connecting said first and second reservoirs, said pipe including at least: an evaporator (EV) that may be thermally connected to a hot source (PC, O) at a temperature higher than that of said cold source; a first condenser (C1) and a second (C2) condenser situated on either side of said evaporator and adapted to be thermally connected to said cold source. Heat transfer system including at least one such device. Method for cooling or precooling an object by means of such a device or system.
