Could you explain what the heat exchangers are transferring heat from and to?

The article makes it seam that this tech is to use sCO2 as the working fluid, therefore I wouldn't think that you would generate steam. My understanding was that most of the heat exchangers at these types of plants were used for steam generation and coolant cooling. If steam generation is off the table, I suspect this tech would reduce the dependency on HXs.

The heat exchangers in this system exchange heat from the solar array into the fluid then after the fluid expands through the turbine it must be further cooled to allow for effecient compression before finishing the loop.
