1. A heat exchange device for receiving a high-pressure fluid and outputting a low-pressure fluid, the heat exchange device comprising:
a low-pressure chamber having a first wall for enabling heat exchange and having an output portion in communication with an outside of the heat exchange device to output the low-pressure fluid; and
a high-pressure chamber disposed in and enclosed by the low-pressure chamber, having an input portion in communication with the outside of the heat exchange device to admit the high-pressure fluid, and having a plurality of nozzles in communication with the low-pressure chamber and having at least one cooling wall free of said nozzles, wherein a primary cooling area is defined between each said nozzle and the first wall of the low-pressure chamber, and a secondary cooling area is defined near the at least one cooling wall, with a temperature of the primary cooling area being lower than a temperature of the secondary cooling area,
wherein a fluid discharged from the nozzles undergoes a pressure drop, enters the low-pressure chamber, and undergoes heat exchange through the first wall so as to be turned into the low-pressure fluid,
wherein the low-pressure fluid undergoes heat exchange with the high-pressure fluid in the high-pressure chamber via the at least one cooling wall in the secondary cooling area and is then discharged from the output portion of the low-pressure chamber.
