Cooling systems configured for use in a WHR system, including an inlet header fixedly disposed on a first end of a condenser, the inlet header fluidly coupled to a heat exchanger to receive the working fluid, and a receiver fixedly disposed on a second end of the condenser opposite the first end, the receiver configured to receive the working fluid from the condenser are also disclosed.

A cooling module is coupled to an engine system and a Rankine cycle waste heat recovery system. The cooling module includes a heat exchanger for cooling a fluid of the engine system and a condenser for cooling a working fluid of the Rankine cycle waste heat recovery system, both of which extend in a width direction of the cooling module and are porous to a flow of cooling air in a depth direction of the cooling module. The condenser includes a first tubular header that extends in a height direction of the cooling module. A working fluid transfer tube fluidly couples the first tubular header to the Rankine waste heat recovery cycle system. The working fluid transfer tube has a first portion extending in the depth direction and a second portion extending in the height direction, the second portion being adjacent to the first tubular header in the width direction.

The disclosed apparatus and control system produces a single, on demand, energetic gaseous working fluid from any heat source. Working fluid in a liquid phase is released into a heat exchange tube in the form of very fine droplets or atomized mist, where it is rapidly heated to its gaseous phase. The gaseous working fluid can continue to absorb heat before exiting the heat exchange tube to perform work. The disclosed system controls the release of working fluid into the heat exchange tube and/or the heat energy to which the tube is exposed, resulting in a flow of energetic gaseous working fluid that can be quickly adjusted in response to changing conditions without a large pressure vessel.

An arrangement (37, 24) receives information about the cooling to estimates cooling for the working medium in the condenser (19) controls the adjusting arrangement (13, 16, 24, 38) such that the coolant in the condenser inlet line (17) provides the estimated suitable cooling of the working medium in the condenser (19).

A system and method for providing dry cooling of a source liquid, having a plurality of heat exchangers which depolymerize and polymerize a polymer. Specifically, the depolymerization process is endothermic and draws heat from a source liquid in a first heat exchanger, and the polymerization process is exothermic and expels heat from a second heat exchanger. Additional heat exchangers and holding tanks may be incorporated in the system and method. In some embodiments the system further provides additional cooling of the polymer prior to depolymerization using cooler night ambient air.

A second working fluid loop converts a portion of the condenser of the first working fluid loop into the boiler for the second working fluid loop in which the first and second working fluids in these respective loops are different. Thus, the energy output of the plant may be increased by the addition of a selectively operated secondary loop without an increase in fuel consumption.
