The circuit comprises an evaporator device (10) adapted to receive heat from a hot body (CC), a condenser device (12) adapted to transmit heat to a cold body (CF), a first conduit (14) through which a working fluid, in vapour phase, flows from the evaporator device (10) to the condenser device (12), and a second conduit (16) through which the working fluid, in liquid phase, flows from the condenser device (12) to the evaporator device (10). The evaporator device (10) comprises a first evaporator portion (18), which is in fluid communication with the second conduit (16) and acts as a compensation chamber containing the working fluid in liquid phase, a second evaporator portion (22), which is in fluid communication with the first conduit (14) and contains the working fluid in vapour phase, and a porous wick (20) arranged between the first and second evaporator portions (18, 22) in such a way that the working fluid moves by capillarity from the first evaporator portion (18) to the second evaporator portion (22) through the porous wick (20). The circuit further comprises first temperature-sensitive flow control means (30, 32) configured to interrupt or allow the flow of the working fluid along the circuit when the temperature of the working fluid passing through the evaporator device (10) is respectively lower or higher than a first threshold value, and second temperature-sensitive flow control means (34, 36) configured to interrupt or allow the flow of the fluid along the circuit when the temperature of the working fluid passing through the condenser device (12) is respectively higher or lower than a second threshold value less than the first one. |
