摘要： A power pack for converting waste heat from exhaust gases of an internal combustion engine to electrical energy includes a working fluid loop fluidly connecting an evaporator, an expander, a condenser and a pump. The power pack also includes a working fluid tank fluidly connected to the working fluid loop between an outlet of the condenser and an inlet of the pump. The working fluid tank has a single working fluid port operable to receive working fluid from the outlet of the condenser and to supply working fluid to the inlet of the pump. The power pack also includes a power pack control unit in communication with the working fluid tank. The power pack control unit is operable to change a pressure of the working fluid in the working fluid loop at the inlet of the pump by changing the pressure of the working fluid in the working fluid tank.

摘要： In an exhaust heat recovery device provided with a Rankine cycle device, a clutch for transmitting and interrupting power between an engine and the Rankine cycle device is released appropriately to prevent the Rankine cycle from becoming a load on the engine. An exhaust heat recovery device 1A includes a Rankine cycle device 2A, a power transmission mechanism 3A, and a control unit 4. The power transmission mechanism 3A has a clutch 31 and is capable of transmitting power between an engine 10 and the Rankine cycle device 2A when the clutch 31 is engaged. The control unit 4A controls the engagement and disengagement of the clutch 31 based on a first correlation value correlated with consumed power when the Rankine cycle device 2A is started, and a second correlation value correlated with consumed power of the Rankine cycle device 2A when the output of the Rankine cycle device 2A is negative during the operation of the Rankine cycle device 2A after the start-up.

摘要： A two-phase thermodynamic power system includes a capillary device, an inline turbine, and a condenser for generating output power as a generator or receiving input power as a refrigerator. The capillary device, such as a heat loop pipe or a capillary pumped loop, is coupled to the inline turbine for generating output power for power generation or for receiving input power for powered refrigeration. The capillary device receives input heat that is used to change phase of liquid received from the condenser into vapor for driving the turbine. The power system is well suited for space applications using a radioisotope heat source, using waste heat from a radioisotope power system as a heat source, waste heat from spacecraft components such as electronics as a heat source or solar energy as a heat source. The heat source is useful for driving the capillary wick as well as a superheater for increased power efficiency and lifetime operation. The power system is well suited for space receiving heat from a heat source to produce useful mechanical energy. The refrigeration system is well suited for receiving input mechanical power to the turbine for removing waste heat from a spacecraft at a low temperature and rejecting that heat into space at a higher temperature.
