| 摘要 |
The invention provides a method for a thermally activated closed loop heat transfer system, and requires no other external power source other than the heat which it is transferring. The system is based on a two-phase (liquid/vapor) working fluid, with heat input through an evaporator and heat rejected through a condenser. All of the mechanical power produced by an engine, driven by the high vapor quality fluid leaving the evaporator, is consumed by the pump. The pump drives the low vapor quality fluid leaving the condenser back to the evaporator. Nearly isothermal heat transport can be achieved when using a pure or azeotropic working fluid, since the operation only requires the evaporator pressure to be marginally higher than the condensers pressure. |
